Portable Air Conditioners Ensure Economy And Convenience

Small is beautiful and convenient and so is the portable air conditioner as it can be shifted from one place to the other very easily. Read on to find out all the other advantages.

With the onset of the damp weather, it becomes difficult to survive without constant central air conditioning but that can prove to be quite expensive. The answer to this problem is a portable air conditioner as it has many advantages. It is easy to shift from one place in the home to another and that makes a portable air conditioner the ideal cooling system solution for your home, office or industrial site.

The portable air conditioners are easy and quick to install, as they do not involve any lifting or tearing up of windowsills. Moreover it can be shifted very easily from one place in the home to the other. For taking care of the hot spots in the central air conditioning, the portable air conditioners are far more convenient than window air conditioners. It is also ideal for window shapes, which present problems for installation. There is nothing like portable air conditioners for use as a spot cooler in the home.

A portable air conditioner is an excellent choice for saving money as just one unit needs to be purchased and it can be shifted easily to where you need it as it is mounted on castors and some can weigh only about 36 pounds. Moreover, as only one room is cooled at a time instead of the whole house, the total energy consumption is very low as compared to other air conditioning systems.

Another advantage of portable air conditioners is the energy efficiency that they provide. The average efficiency is in the 8 to 10 range although some are as high as 15, which is 50 percent better than most older central air conditioners. The small size of the portable air conditioners is very advantageous and as such it can fit in a corner or against a wall. It functions like an effective dehumidifier if you do not vent the warm exhaust air out through a window and its size is also the same as that of a room dehumidifier.

In order to reduce humidity and allergies, even the small ones remove 35 pints of moisture per day from the room air. The portable air conditioners also use the heat-exchange principle as the other air conditioners to cool and dehumidify the air. The operating principle is also similar to a window air conditioner as the room air circulates over cold evaporator coils to cool and dehumidify it inside the unit. The room air is exhausted outdoor after flowing over the hot condenser. There is no chance of already-cooled indoor air escaping outside as two ducts are now used.

Nowadays, you have electronic controls in most models and you can set the desired room temperature, blower speed, start and stop timer, and operation mode (cool, dehumidify, heat). The portable air conditioners also have hand-held remote control with which you can conveniently change all the settings as per your need.

The other features of portable air conditioners include a built-in air cleaner with an optional charcoal filter and oscillating louvers to distribute the cool air throughout the room. You can also switch off the louvers to direct the flow of air towards yourself, if you so desire.

How To Clean Your Air Conditioner Like A Pro

Very little is required to clean a window air conditioner, except lots of patience. If patience is something you lack then it is a job you should turn over to the local appliance serviceman. But for those who want to give it a try - read on.

Very little is required to clean a window air conditioner, except lots of patience. If patience is something you lack then it is a job you should turn over to the local appliance serviceman. But for those who want to give it a try - read on.

Tools --------------------

Tin can or container (old muffin tin works well also)
Vacuum cleaner
Long handled brush (an old toilet brush works well)
Oil can
Rags
De-greaser or spray detergent
Selection of screwdrivers (Philips, Flat bladed, 1/4" socket head)
Fin tool (optional)
New filter (if disposable type)

Lets get started ---------

1. Start by removing the filter from the front grille. If it is a disposable type simply replace it with a new one. Other types are made in a plastic frame and can be cleaned and reused. To clean a reusable type lay it flat in the sink and sprinkle surface with laundry detergent. Then cover with about one inch of hot water. Just enough so the filter is submerged. Soak for 15 minutes. Remove from water and rinse with warm water. Hang up to dry while proceeding to next step.

2. Next, remove the front grille from the main body of the air conditioner. They usually pivot on 2 spring clips at the bottom. It is usually removed by pulling the grille gently forward while pushing it down at the same time. If there is resistance then look for hidden screws. Look near the top edge of the grille or behind the control knob door. Once removed place the grille aside until later.

3. Carefully remove metal cover of air conditioner to expose inner workings. Once all the screws are removed lift the cover straight up. Do not let it hit the other parts as it can have sharp edges. This is where the old can comes in handy (ice cube container or muffin tin works well also). Use it to keep track of all the screws you will be removing. An air conditioner will often use a number of different types and sizes of screws. Segregate them from each other or confusion will result when we start reassembly.

4. Check the fan motor for any oil holes or oil plugs. If the motor has oil plugs they are usually rubber. Use caution when removing because the rubber may have become brittle. Often they will break off in the oil holes resulting in a blockage. If this occurs try to remove the broken plug by using a pin of the tip of a small screwdriver.

Once the fan motor oil holes are exposed add a few drops of oil to each end of the motor body. Use a general purpose (3in1) oil or clean motor oil. A #30 oil is sufficient.
The natural tendency is to over-oil. Too much lubrication is as bad as not enough. Therefore only 3 or 4 drops on both ends of the motor body is sufficient. Add the oil slowly, pausing a few seconds between each drop. If you add it too quickly over-lubrication will result.

5. Use the brush to remove surface dust and dirt from the evaporator (front fins). Use only an up and down motion. Do not go side to side or allow the fins to be bent over. The fins are very soft aluminum and can be damaged easily.

Once surface dirt is removed, spray with de-greaser or cleaner. There is a good product on the market called HVAC cleaner. As the name implies it is meant for Heating, Ventilation, and Air Conditioner coil cleaning. If this is not available the Fantastic Spray cleaner used in kitchens and bathrooms works quite well.

Let stand about 15 minutes or as per instructions on de-greaser can. This will allow cleaner to loosen any hidden dirt. Remove dirt and excess cleaner by slowly pouring warm water into fins. Do not allow the water to enter any electrical connections or components that may be near the coil. As an added precaution cover the motor with one of the cloth rags. to protect it from the water.

Do not use any form of high pressure air or water because this can drive dirt farther into fins. Also, use extreme caution as these coils are filled with high pressure refrigerant.

6. Straighten any bent fins. Use a fin comb if available. If no fin comb then use something soft such as a Popsicle stick. Straightening the fins will increase the efficiency of the air flow through the coils. This adds to the overall cooling effect produced by the air conditioner.

7. Repeat steps 5 and 6 for the condenser (rear fins) coil. A plastic cowling usually surrounds the condenser fins. If so, check the top edge to see if it will lift or open. If it opens this will allow easier access to the condenser fins. Again use caution because the condenser coil is also filled with high pressure refrigerant.

8. Wipe any dirt buildup from both fan blades using a soft rag. Do not bend blades. This would cause a vibration that would harm the motor.

9. Vacuum all surfaces including front and back of grille assembly. Do not forget to vacuum underside of metal air conditioner cover. If the cover contains air holes clean them thoroughly. If necessary use a damp rag.

10. Drain any water left in the base and allow it to dry for few hours.

When completely dry plug in air conditioner and test operation. If everything appears okay unplug and reassemble.

Once reassembly is complete, retest operation to ensure replacing the cover has not affected anything. Adding the cover will tend to twist the frame and can cause interior parts to move out of alignment. This can cause the fan to become noisy. To correct for this problem remove the cover and realign to the main body of the air conditioner. Reinstall the cover and test for noises every time 2 or 3 additional screws are added to the cover.

Finally, cover air conditioner with plastic wrap or an old blanket. Store in a warm dry area. Raise it from floor slightly by placing onto a couple of pieces of wood. This will protect the floor from the metal edges of the air conditioner, and also protect the air conditioner from moisture.

Youre Finished

Repeat this simple procedure every year. If you do, the machine will be ready for many more years of dependable service.

The filter inside the front grille should be removed and cleaned (as in step 1) every month throughout the cooling season. If you are a smoker it should be cleaned every week.In the trade over 30 years as a technician, business owner, and technical trainer.

Automotive Air Conditioner Basic Troubleshooting Tips

If your automotive air conditioner isnt working quite right, here are a few ideas to begin. First of all start with the control panel on your dashboard. Most automobiles have an A/C button that actually turns the compressor on and allows cold air to be circulated. You might have accidentally hit the recirculation button instead of the A/C button. (Dont laugh, I had a friend that spent a week in a hot car and all he needed to do was press the right button.) The second thing to check is the actual function of the controls. Do they move at all? Are they loose and giggle around? The big question is do they feel different from the last time your air conditioner worked? This could tell if the controls are messed up and need replacing. Your air conditioner system may be fine but the controls could be frozen or broken. If your controls seem to be functioning, lets move to the blower fan. Turn on your car and start youre air conditioner as you normally would. Then turn your blower to its highest setting. Can you here your fan blowing? If you can hear it, does it sound weak or whining. This could signal that your blower motor is malfunctioning or needs to be replaced. If it doesnt work at all, check the fuse for the blower motor. The fuse for your blower motor should be located in the fuse box under the dash. Most automobiles have the fuses clearly labeled. First take out the blower fan fuse with the removal tool provided in the fuse box. A blown fuse should be easy to identify. However if you are unsure, replace it with a similar rated fuse and try your blower again. If that fuse blows you may have a bad blower motor or a short in the circuit. In this case, you will need an authorized mechanic to fix it.

If the blower fan is working properly and you can only get cold air out of the defroster vents, you may have vacuum-system supply line problem. To check for this, look for a small black plastic tube going from the engine area through the dash. It is usually right by the refrigerant lines. Check this tube and see if it has holes or is not connected. If all of these little tips are not helping and youre A/C doesnt blow cold air no matter how many switches you turn on or off, you will probably need an certified mechanic. Good luck and stay cool!

For a Healthy Greenhouse Supply Good Air Ventilation

For optimal functioning of your greenhouse, supply sufficient air ventilation at all times.

The air inside a greenhouse is heated by re-radiation of solar energy by objects inside the greenhouse, or, sometimes, by means of artificial heating.

It may reach a point where the temperature inside the greenhouse grows uncomfortably high for the plants. If this happens, you need to implement a good greenhouse ventilation system to exchange some of the warm air inside for cooler air from outside.

Because warm air rises, it is convenient to allow it to escape through vents at the highest point of the greenhouse. Cool air can gain access through natural means - for instance, leaks where glass overlaps - or through side vents set lower down in the sides of the greenhouse. It's especially important to provide lean-to or circular greenhouses, or greenhouses used to grow alpine plants, with an adequate fresh air supply.

A rule of thumb for small greenhouses is that the vents should be equal to 25 - 30 percent of the floor area.

It's best to have an automated system to control the opening and closing of vents. This can be achieved by thermostatically controlled electric motors, or, on a smaller scale, by expansion vent units. Roof vents are best positioned alternately on both sides of the roof, with side vents set to match. Don't forget - if side vents are placed at ground level, you need to cover them with wire netting to prevent unwanted guests like mice or cats from gaining access to the greenhouse.

To prevent cold or wet spots, circulating fans can be used to mix the air inside the greenhouse. Extractor fans will pull air out of the greenhouse, and you obviously need a means of allowing fresh air in to replace the lost air. It's possible to use fans to pull air into a greenhouse, but, in practice, extractor fans work more reliably. Air vents are the normally preferred means of allowing air in.

Extractor fans are controlled by an air thermostat - and they must be large enough to move sufficient quantities of air. A good greenhouse supply retailer should be able to recommend the best type of fan for your requirements. Normal domestic extractor fans are not suitable - those used in greenhouses have larger blades which turn more slowly.

Moisture jets or absorbent pads can be used alongside fans to add or remove moisture from the incoming air to help maintain the correct humidity level in the greenhouse atmosphere. With a little planning and forethought it's quite easy to maintain a good greenhouse supply of fresh air to keep your plants happy!

HVAC Air Filters Amongst The Best Air Filters For Air-Conditioning

Most of the time people are not aware about the dangers of air pollution inside our rooms. Our rooms are most polluted places in the cities we live. A number of small particles of dust, dirt, and pollen circulated within our living rooms and we continue breath such airs for long hours. The particles in air can increase our allergy symptoms or even can trigger some of the diseases. We only care about pollution in the cities and HVAC air filters help us in controlling air pollution especially inside our homes. HVAC air filters are widely used in various applications such as air conditioning, heating and other ventilating applications. These are designed in such a way so that the HVAC air filters provide us the best air.

Although we might use one or other equipment fitted with HVAC filter so that we inhale pure air, but we hardly realize the damage a room air can cause to our health. We live more than 50 percent time in our room, which is many times more polluted than the air outside the room, and we ignore it always. HVAC filters are highly efficient filter papers used in our ventilation systems and are able to absorb this smaller number of particles from our room air.

If we look of the indoor pollutants, we will find a number of hazardous pollutants that are dealt by us daily in our houses. These are sometimes man made pollutants and we should try to avoid them and if it is not possible to avoid them, what we can do is best we can use HVAC air filters in our ventilation systems so that the pollutant created by them do not remain prolong in the air.

A large number of companies are producing HVAC air filters and some of the company?s products are excellent in the performance. There are huge positive feedbacks have been received for polyester based HVAC air filters and now these are widely been used for various applications. These are not only useful for residential buildings but these HVAC air filters also suit best requirements of commercial buildings.

HVAC air filters are the best choice for today as many routes that probably we might not know are creating more and more indoor pollution. The air pollution level in some of our houses is continuously rising and smoking is one of the reasons for it. More and more people smoke and that too inside the living rooms and fine particles produced by smoke are deadly enough to create hundreds of times more pollution than the pollution created by a diesel vehicle on the road. We must understand the needs to control this harmful nature of indoor pollution and therefore we should use an HVAC air filter especially in our ventilators.

Are Hybrid Cars Hazardous?

With all of the talk of hybrid vehicles many people are singing their praises about these lightweight, fuel-efficient cars. But are there hazards to driving a hybrid? Is there really anything to worry about? Let's take a closer look at potential hybrid hazards.

One of the biggest concerns often talked about when it comes to hybrid vehicles has to do with those personnel responding to accidents involving a hybrid. Many traditional looking cars such as the Honda Accord and Ford Escape are being built with hybrid engines and rescuers might experience some difficulty at the scene of an accident identifying one as such. The reason the identification is crucial is that as compared to conventional gas powered cars, hybrid vehicles have a tremendous amount of electricity coursing through them and thus could cause injury to rescuers and further injury to drivers already hurt by the crash. Many people believe that the solution to this problem is for automakers to affix a label on the driver's side visor stating that it is a hybrid vehicle, equip with all the features that this kind of car entails.

New hybrids are bursting onto the market at an increasing rate and therefore all first responders need to be taught about ways in which hybrid cars differ from more traditional non-hybrid models. Lack of education could result in safety measures being compromised and injuries taking place. To use the battery in a hybrid to illustrate the point, in some hybrid models the battery carries with it a charge of up to 500 volts and is powered both by gasoline and electricity. Compare this with the voltage of a typical non-hybrid car, which is in the area of 12 volts. First responders need to be taught where the battery is located in a hybrid car and how to cut the cables without risking being electrocuted by the high voltage that the battery puts out. This is particularly important when machinery such as the Jaws of Life is required to physically remove a passenger in imminent danger from a car. It cannot be emphasized enough, without proper training, more serious injury, and even death, could result.

This problem is being addressed by manufacturers of hybrids with Honda and Toyota going to the front of the line on safety procedures. Hybrid cars are being suited with color codes so first responders can easily comprehend the flow of electricity in the car. Honda hybrids use the color bright orange to designate the high-voltage power line which helps reduce safety risks for rescuers responding to calls.

Concerns about hybrid hazards have led Honda and Toyota to create their own individual safety guides for rescue personnel. Every fire department in the United States received a copy of these guides to be made available for their staff to educate themselves. Toyota has just completed new guides for its latest hybrid vehicles, the Highlander and Lexus. These guides can easily be read online by any member of the public, whether they are emergency workers or not.

In South Florida, with its many canals, many people have expressed concerns about the hybrid hazards involved in water submersion, as these kinds of accidents are common in this area of the state. Manufacturers of hybrid vehicles say that the only thing emergency personnel need to keep in mind in regard to safety issues is to remember to make sure the car's ignition is turned off once it is out of the water.

Speaking of the car being turned off, that is another issue for hot debate when it comes to talk of hybrid hazards. Hybrid cars are made differently than traditional gas powered vehicles in that it is not always easy to tell if they are off or still running. Most traditional cars one need only feel the hood of the car to make a correct determination but hybrids can be tricky- a hybrid can appear to be turned off when in actual fact it is in silent electric mode and very able to plow over an unsuspecting person if any movement or pressure is applied to the accelerator. One possible solution to this serious hazard put forth by the fire department in Texas is to place chocks under the wheels if it is not known whether the car's ignition is still on or not.

HVAC Named One of the Top 50 Most Promising Job Fields in America

What makes the list of the top 50 fastest growing career fields in the Unites States and have annual earnings above the US median income of $28,770? According to Career Builder.Com coming in at number 40 is Heating, air conditioning, and refrigeration (HVAC) mechanics and installers with a median pay of $36,260.

Part of the reason for this growth is concern for the environment has prompted the development of new energy-saving heating and air-conditioning systems. An emphasis on better energy management will lead to the replacement of older systems and the installation of newer, more efficient systems in existing homes and buildings. Also, demand for maintenance and service work will be increased as businesses and homeowners strive to keep increasingly complex systems operating at peak efficiency. Regulations prohibiting the discharge and production of CFC and HCFC refrigerants should continue to result in the need to replace many existing air conditioning systems or modify them to use new environmentally safe refrigerants.

Job prospects for heating, air-conditioning, and refrigeration mechanics and installers are expected to be excellent, particularly for those with training from an accredited technical school or with formal apprenticeship training, and especially in the fastest growing areas of the country. A growing number of retirements of highly skilled technicians are expected to generate many job openings. In addition, employment of heating, air-conditioning, and refrigeration mechanics and installers is projected to increase faster than average for all occupations through the year 2014 by the US Department of Labor. People and businesses depend on their climate-control systems and must keep them in good working order, regardless of economic conditions.

If you are entering the HVAC job field, it is recommended that you first enroll in technical training from a quality technical or trade school. Many options exist, so it is in your best interest to find a school that offers quality, cutting edge training. One example school on the forefront of HVAC training is The Refrigeration School, Inc (RSI) of Phoenix, Arizona. An accredited technical school that offers courses in Refrigeration, Air Conditioning & Heating Technologies, Electrical Technologies, Electro-Mechanical Technologies and Associate of Occupational Studies in Mechanical Maintenance Engineering. Implementing their new STAR system, instructors can emulate scenarios that would be found in real world situations, directly in the classroom. This new technology utilizes a computer interface to "break" HVAC systems and allows students to diagnose and repair the systems in real time. To learn more about the STAR system, visit The Refrigeration School Inc.'s HVAC school resource.

HVAC Maintenance

Does HVAC Maintenance Pay For Itself?

Most people would not even consider not changing the oil in their vehicle. Maintaining your HVAC system is no different. By getting involved in a quality maintenance program you will reduce energy costs, extend equipment life, optimize comfort conditions and increase system reliability. Just knowing your equipment is operating safely is a peace of mind in itself.

Many businesses use what I call ?the breakdown maintenance program.? In other words ?I?ll worry about it when it breaks.? We all know this almost always happens at a inconvenient time like when it?s 20 below zero or 95 degrees in the shade. This way of handling things is also very hard on your equipment and may decrease the life of it by as much a half. Maintaining is much cheaper than replacing.

Here are some of the savings you can expect from a quality maintenance program:

Adjusting operating sequence of equipment 25-35%

Cleaning Coils 5-15%

Changing dirty air filters 10-15%

Removing scale from condenser coils 25-30%

Adjusting air/fuel ratio of burner 15%

Cleaning burner assembly 15%

Removing soot from fire side of burner 9%

Eliminating V-belt slippage and pulley alignment 15-20%

Not to mention the money saved in break down service calls.

So if your not already set up with some type of HVAC maintenance program you may want to seriously consider talking to your local HVAC contractor about getting set up with a program to meet your needs.

The Need for Heating and Air Conditioning Technicians - HVAC

Regardless of where you live, people need heating or air conditioning HVAC (Heating, Ventilation, & Air Conditioning) job opportunities are dramatically increasing all over the United States. While the need for Air Conditioning and Heating Technicians steadily rises, the amount of trained graduates to fulfill the positions has not. Because of this, HVAC technicians are finding themselves with great job security as well as increasing salaries. Here are just a few reasons why more people are turning towards a career in the HVAC field everyday:

1. HVACR certification requires quick and easy training that often lasts as little as nine months. According to Jon Cline of RSIAZ, a heating and air conditioning training school in Phoenix, Arizona, ?Of the approximately 7,000 technicians trained in 2004, very few graduated from other than a career school such as ours. Traditionally, career school programs for HVACR are from 6 to 15 months. Graduates of accelerated training programs find a high employment demand and starting salaries in the range of $32,000 to $35,000 with as little as six months of training.?

CASE STUDY:

Typical Program breakdown:

Day Program Night Program

Electrical Technologies 3 months 4 months

Refrigeration Air Conditioning and Heating Technologies 6 months 9 months

Electro-Mechanical Technologies 8 months 12 months

Mechanical Maintenance 12 months 24 months

Graduates from the Electro-Mechanical course have completed the Air Conditioning, Refrigeration Heating AND Electrical portion of our course. Therefore when they graduate they are an Air Conditioning, Refrigeration, and Heating Technician AND an Electrician. This is important to employers because they only need to hire one person to perform both functions.

Graduates of the Associate of Occupational Studies in of Mechanical Maintenance Engineering add an additional 5 months of training to the Electro-Mechanical Course to prepare a graduate to work in the large commercial industry.

2. The demand for HVAC technicians and engineers is high and steadily increasing, thus the wages are much higher than similar jobs in the labor industry.

3. Because most unions and employers only require less than 2 years of training, a career in HVAC costs much less then a four year school.

It is no wonder why heating and air conditioning technician jobs are one of the fastest growing employment opportunities in the world, and they offer involvement in business ownership. In fact the U.S Department of Labor estimates that there will be a 17% increase of jobs in this field over the next 2 years.

Why are heating and air conditioning technician jobs at a premium?

Heating ventilation and air conditioning is a very important factor in residential homes as well as businesses, this is because being comfortable is something every aspects whether it?s in their cubicle or bedroom. Heat ventilation installment only requires two semesters of training.

Little known facts about HVAC ( Heating, Ventilation, & Air Conditioning) jobs:

- An average hourly wage for a certified worker can be as much as $10-15 higher when compared to a non-union worker in the HVAC industry.

- Due to the overwhelming demand for heating and air conditioning technicians many technicians clear $200.00 a day without a college degree.

- Because of the extensive training in the HVAC industry business ownership is highly implicated in these fields

HVAC Noise: Solving a Common Noise Problem

Noise pollution caused by rooftop and ground-level HVAC equipment including chillers, boilers, and air handlers has become one of the most annoying as well as dangerous environmental problems in cities worldwide. As urban noise increases and residential growth multiplies, residents and communities are demanding better noise reduction solutions for heating, ventilation and air conditioning equipment. Outdoor community noise problems caused by commercial and industrial HVAC systems may require an acoustically engineered Sound Barrier Wall.

Sound barrier walls have been used extensively for years in the transportation and industrial fields. A sound barrier wall is an exterior structure, normally made of masonry or earth, designed to protect sensitive land uses, such as residential areas from noise pollution. These noise pollution abatement products are now being used to help eliminate unwanted noise from HVAC systems as well.

Traditional material for noise barrier walls for HVAC systems has been reflective products. Reflective products, like concrete or brick, simply redirect the unwanted sound waves in other directions, and can actually increase noise by unintentionally reflecting sound waves. There is a better solution. Absorptive sound enclosures and architectural screens actually absorb the unwanted sound waves, minimizing the risk of unintentional reflected noise. Absorptive sound walls reduce reflections and are able to maintain the effectiveness of the barrier. Therefore, the overall noise level is reduced. The advanced materials found in absorptive barrier walls present a much more effective noise barrier solution. There are different solutions for this problem such as the LSE System, an absorptive sound barrier created by Sound Fighter Systems, that actually absorbs the sound waves that hit it, thereby eliminating unwanted noise.

So, if you are facing problems with noisy HVAC equipment an absorptive sound barrier wall is obviously the most effective noise mitigation solution available for this very demanding application. Absorptive walls outperform and outlast all other noise reduction products. Plus, many systems such as the LSE System are an aesthetically pleasing HVAC sound wall with the added benefit of noise pollution reduction.

Murray Stacy is Vice President of Sound Fighter Systems, LLC, which has been researching, designing and manufacturing highly efficient absorptive noise barrier walls since 1973, making it the oldest established manufacturer of such products in America. Sound Fighter walls have been produced for unique noise mitigation applications around the world, and several of the company's walls are in their 30th year of effective service. http://www.soundfighter.com
