Benefits Of A Portable Air Conditioner

There are mostly three kinds of air conditioners which are used for commercial and domestic purposes. These are:

- The central air conditioners,
- The window air conditioners, and
- The portable air conditioners.

While the central air conditioners are meant for entire houses or offices, the window and portable air conditioners are meant for a smaller area, generally a room. The central air conditioners require a healthy investment and also your house needs to have the provisions to have it installed. Window air conditioners also need to be fitted to the window or a wall and requires installation facilities.

Portable air conditioners are much better on that count as there is no installation hassle and you can just put the plug in the socket and enjoy the nice cooling effects of an air conditioner.

Of course, being portable also allows it to be carried anywhere we want them to. For commercial purposes, the portable air purifiers are generally used in conjunction with the central air conditioners. Even with the best laid out duct network and proper outlets in a large factory floor there remains a few hot spots where air form the central air conditioner do not reach. For such areas placing a portable air conditioner can solve the problem. So, portable air conditioners can be of great benefit to many a business and warehouse owners. A comfortable environment ensures that their workers can focus on their work and not worry about other basic things.

Portable air conditioners are great for domestic purposes also. If you have a small family and most of the rooms in your house are not occupied at one given time, then you can go for portable air conditioners. That way you don?t have to invest separately on air conditioners for each room but carry your portable air conditioner where you are. When you are watching a movie on your television, place it in the living room. When it s time for bed you can just move it to your bedroom.

Portable air conditioners are also generally very durable. They are also equipped to deal with the most severe environments.

The portable air conditioners these days available in the market are based on two kinds of technologies ? they use either the Freon technology or the evaporation technology. Though the latter is a bit expensive, it is the most effective and popular version these days.

Air Conditioner Rental Advice

Air conditioners (AC) are essential in many countries. However, temporary or short-term businesses, business meetings, wedding receptions, and high school or college functions are events that might require renting air conditioners. There are a lot of rental companies that lease air conditioners for a short or long period of time and charge a monthly rental fee.

There are numerous companies that offer air conditioners to rent at discounted prices, especially during the hot summer months. It is advisable to order an air conditioner well in advance, as the demand rockets during summer. When someone contacts a rental company for cooling necessities, the rental company usually sends one of their experts to examine the room. They will then recommend the right kind of air conditioner that will cool the room. The rental company provides this service for free. The company will quote a rental fee that is usually negotiable. An official contract is signed and the air conditioner is installed

Air conditioner rental companies deal in a variety of units, such as window, split, central, portable, industrial and many more. Usually, the type of AC is determined based on the venue that needs cooling. Prices differ in accordance with the type of AC installed. Central AC costs the most, while windows units are the least expensive. Some companies charge a deposit before installation. Any damage during usage is recompensed from the deposit money.

Choosing The Right Air Conditioner For Your Home

During the hot summer afternoons and warm muggy nights, an air conditioner can help to keep us cool and improve our ability to deal with extreme heat. Just as a heating unit provides a customized temperature, an air conditioner can be controlled to maintain a comfortable temperature of our choosing.

If you have a small home or find that one room is particularly hot, then a single room air conditioner may be the answer for you. These units are portable, meaning they can be moved from one room to another and are much less expensive than a large air conditioner that heats an entire home.

If you have a large home or simply do not wish to purchase multiple single room air conditioner units, then a larger model will be ideal for cooling every room in the house. Large air conditioner units usually begin at $2,000.00 and go up, depending on the manufacturer or company that you purchase from. These units require professional installation, which is usually done by the company who sells air conditioner units. Upon delivery, they will install the air conditioner and provide the customer with any warranty information that accompanies the unit.

As with most large purchases, including home appliances and accessories, a warranty is provided by the manufacturer. This is typically only available on brand new models and will cover certain repairs or replacements at not cost to the buyer. For example, if a defect relating to materials or workmanship is discovered during the warranty period, the air conditioner will be repaired free of charge. Most warranties do not cover improper care or negligence that results in damage or the products inability to function.

If a customer chooses to handle the installation themselves, they will need to be familiar with the process. Otherwise, they may end up calling a technician later and spending more than if they allowed the retailer to install their air conditioner initially. Once an air conditioner is properly installed, a temperature box will be placed inside the home that will allow residents to adjust the temperature inside. Even on the warmest day, an air conditioner can make your home a comfortable haven away from the heat and humidity that often accompanies the summer months.

Extreme heat can result in headaches, profuse sweating, dehydration and even more serious complications for the elderly or those with weakened immune systems. An air conditioner can help to ease the discomfort of heat while reducing the danger associated with over exposure to extreme temperatures.

Effective Air conditioners - 9 Ways to Cut Your Energy Bill by Half

Do you know that, in summer, the average American family pays about 40% of their energy bill for air conditioning of the house? But it doesn't have to be this way, Use these simple tips to help you keep your house cool and significantly reduce your energy bills during the hot months. 1. If you need to cool only one room, don't use your central air conditioning. Invest in a portable air conditioner, instead. Modern portable units have a very high energy efficiency rating, so it will cool your room effectively and save you a lot. 2. Install mini-blinds or white window shades. Mini-blinds can be very effective and can reduce heat gain from direct sunlight by 40-50 percent. You can also hang bamboo shades or tightly woven screens outside your windows. This will stop up to 80 percent of the sun's heat from getting through your windows. 3. Keep all windows closed during the day. At night you can open them for ventilation and switch on a fan instead of an air conditioner. 4. If you are using a mini split air conditioner, make sure that the outside compressor is well shaded. However, trees and shrubs shouldn't be planted right next to it; it needs some room for air flow.

5. It is best to clean your air conditioner filter at least once a month. Dust build-ups can significantly reduce air flow.

6. When buying an air conditioner unit, make sure that it is the right size for your room. A unit that is too small will not cool your room effectively, and an A/C that is too large will consume much more energy than necessary. See recommendations for proper air conditioner sizes for your room.

7. If you use central air conditioning, seal all A/C ducts. Insulate ducts that run through rooms that don't need cooling, like the basement or the attic.

8. If your air conditioner is old, consider replacing it with a modern high efficiency unit. Older A/C systems have a SEER (seasonal energy efficiency ratio) of only 6 or 7, while the best air conditioners on the market today offer SEER as high as 13. That means that it will consume almost 50% less energy.

9. Cooking, drying cloth or dishwashing generates a lot of heat. Try to delay these activities until the evening, when it gets cooler.

Most people just switch their air conditioners on and set the desired temperature. This will cool your room, of course, but it will cost you, too. Furthermore, excessive energy consumption is not environmentally friendly, so by following our simple advice you could not only save on your bills, but you could also help to reduce pollution in your area.

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
