Air Conditioners: Increase Efficiency And Reduce Electricity Bills

The SEER Rating

An abbreviation for Seasonal Energy Efficiency Ratio it is unit which helps you understand how efficient your air conditioning unit will be. What the SEER actually provides is a ratio of the cooling output and the power required for that. Of course other variables like climate are also factored in while measuring the SEER ratings for a particular model.

The higher the SEER rating for you air conditioner the better it is for you. O f course, if you want a unit with higher SEER rating you will have to pay extra, but in the long run it is you who stand to gain. And this is because you will be saving much more on your electricity bills than you had been previously. In fact it takes about three to four years for you to appreciate the extra dollars you had paid. Since investing in an air conditioner is a long term thing, you can give yourself three to four years.

So, if you are planning to repair your old air conditioner, our advice would be to get a new one, one with a SEER rating of 12 or more. There is just no point in wasting time and money on an air conditioner with a SEER rating of 7 or 8 in today?s time.

Installation of the Central Air Conditioning System

If you plan to install a central air conditioning system, make sure that the outdoor compressor is installed under a shelter where the compressor will have enough shade. Believe it or not, this alone can reduce the energy consumption of the unit by 10 percent. Also ensure that there is a one-foot airflow all around the unit.

Get a Programmable Thermostat

This is another thing that can cut your energy bills significantly. This would allow you to have the temperature in the room to rise steadily, thus helping the air conditioner to consume less power. And since the temperature change will be gradual, you will also hardly sense it.

Maintenance

Of course, you have to maintain your air conditioner to see that it can perform at its best. Regularly clean the filters and see that the air flow is maintained. It is best to clean the filter once every month. Since it is not much of a hassle, all you got to do is just make a habit of it. It would hardly take any time.

Also clean the coils inside the air conditioner once every year. This will also go a long way in ensuring that the energy efficiency of your air conditioner is maintained at its prime level.

Adjust The Thermostat Levels To Increase The Efficiency Of The Air Conditioner

Be it the hot and scorching summer months or the cold and chilly winter months, it is hard to imagine life without an air conditioner. There are several issues that we need to consider before buying an air conditioner. This would include the make of the air conditioner, the capacity of the air conditioner, the room you would be installing it in, etc. There is also the issue of efficiency of an air conditioner linked to the choice you make.

The efficiency of an air conditioner is important to many people as the running costs of an air conditioner is generally pretty high. With a lower efficiency air conditioner, these costs could sky rocket. However, there are a number of things we can actually do to increase the efficiency of the air conditioner.

The first thing that we need to do is take proper care of the device. Maintaining the air conditioner and its different parts in prime working condition ensures that the unit will work at its optimal level and be more efficient.

Similarly, if we keep the room from heating up too much from the rays of the sun by drawing the curtains, we can further increase the efficiency of the air conditioner.

Another very effective way to increase the efficiency of an air conditioner is by adjusting the thermostat levels of it. By setting it at proper levels you can save significant amount of power consumption. During the summer months try and adjust the thermostat levels at 78 degree Fahrenheit or higher. If you adjust at any lower temperature, you will be spending about 7% extra on your electricity bills for every additional drop of Fahrenheit degree temperature.

Similarly during the winter months adjust your air conditioner?s thermostat level at 68 degree Fahrenheit or below it. This will again save you a lot of power consumption and hence cooling costs.

If you are not used to such temperature in either of the seasons, then it will take time for you and your family to adjust. Don?t just rush into it. First let your family know why you are adjusting the thermostat levels. Then reach the level gradually by changing the thermostat temperature every day by a degree. This would help you and your family to acclimatize better. And in no time you will be saving a lot of extra bucks on your electricity bills. You can even plan for something with those extra dollars to reward yourselves for sticking to the plan.

Benefits Of A Freestanding Air Conditioner

It is a tough job surviving the summer months without proper air conditioning. Generally it is hot, and it is humid too. With an air conditioner installed not only will it cool your surroundings cool but you will also have a less humid place to work or relax in.

There are mainly four kinds of air conditioners available in the market. They are:

1. Central Air Conditioners
2. Window Air Conditioners
3. Freestanding Air Conditioners
4. Ductless Air Conditioners

Of these, the most convenient and economical would be the freestanding air conditioners. There are a number of benefits that the freestanding ones have over the other types. We will list a few below.

First of all, the freestanding air conditioner is the easiest to install. In fact there is hardly anything to install. You only have to plug it in and it is ready to start working. But with window air conditioners, and more so with central air conditioners, you need to go through a lot of installation work. This does not only mean that you have to put up with a considerable amount of hassle, but you also got to spend a significant sum of money to get the units installed. There are no such costs with a freestanding air conditioner.

The other great advantage is that with a freestanding air conditioner you can have it wherever you want to have it. So when you are in your living room with your friends you can have it over there, and when you are back for to sleep after an evening of fun you can have it in your bedroom. The freestanding air conditioners are light enough to be moved around. This means that you can further save on your expenses. If you had window air conditioners you needed to install separate ones for each of the rooms. With freestanding air conditioners you can do with a single unit. Although central air conditioners cool the air of all the rooms together, but they also consume much more power than the freestanding air conditioners. Power is being expended for rooms which are not occupied. With freestanding air conditioners you can reduce your electricity bills.

Since there are no installation issues it can be used anywhere. While window air conditioners require a window or an open stretch of wall and the central air conditioner requires the provisions for ducts, you can place the freestanding air conditioners anywhere.

Business Data Security: A Guide To Server Room Cooling With Portable Air Conditioners

Most buildings aren't designed specifically for the unique needs of a server room, so it's no wonder that many server rooms aren't properly designed in terms of cooling. The solution for most has been to bring in portable air conditioners or spot coolers to take the unique needs of the server room.

Computers and server room equipment need to be kept cool-even in the winter months when heat is being pumped into the building to keep the staff warm. Because there normally isn't a way for the hot air to be diverted from the server room and even less likely that a building's HVAC system allows for controlled temperatures on a room-to-room basis, the problem is a serious one.

Choosing a portable air conditioner: There are several different features to look for when comparing portable air conditioners for use in a server room. The first is the number of BTU's that the spot cooler produces. BTU's, or British Thermal Units are the metric that determines how much heat a particular portable air conditioner can displace.

In order to arrive at the number of BTU's necessary for a portable air conditioner to cool your server room, you'll need to take measurements of the room and any windows in the room, add up the total wattage for the equipment in the room, count the number of lights in the room, and document the number of regular occupants. A portable air conditioning expert can then use this data to recommend a spot cooler with the right number of BTU's to do the job. It's a good idea to get more BTU's than you need currently to handle future growth.

Monitoring the temperature: The ideal temperature for a server room is between 68 and 71 degrees. An acceptable range is between 50 and 82 degrees. Any hotter and you're risking damage to your server chips. When getting a temperature read on the room, keep in mind the number of occupants that spend most of their day in the data center or server room. A person working in the room can add a good deal of body heat, enough to displace about 400 BTU's of cooling power. Also, the current temperature outside will affect the room, as will the air conditioning or heat filling the remainder of the building.

What you'll need is a way to consistently monitor the temperature of the room to ensure that your portable air conditioner is maintaining the temperature properly. There are motoring devices that generate an alert when data center temperatures get out of range and can even point out any hotspots in the data center. Even if your portable air conditioner is doing its job on the overall temperature of the room, it's important to identify hot spots where small fans may be necessary.

The potential cost of not addressing the issue is disastrous. Imagine what your company would do tomorrow if suddenly all of your critical data was gone or inaccessible for several days. The process of brining in adequate cooling for your data center isn't a difficult one. Portable air conditioners can be rolled in and used immediately with about 20 minutes of set up time by a portable air conditioning specialist. Once your server room cooling system is set up, you can rest easy knowing that you've taken precautions to preserve your company's data.

High Velocity Air Conditioners

High velocity air conditioners work by delivering air into a room at a high velocity (roughly two feet per second). This creates air currents that circulate cooler air throughout the room or entire house.

The high velocity systems have certain advantages and disadvantages over the conventional forced air system. For example, the conventional systems moves air slowly. You really don't feel the circulation and there can be dead spaces in rooms if vents were not placed properly. High velocity systems places vents in more locations; thus, there is a more consistent airflow and temperature throughout the house. However, since conventional systems use larger ducts, more air passes through and they are silent. The high velocity systems use much smaller tubes to circulate air and are nosier. Conventional systems are also easier on your pocket, as tend to last longer because of the metal ductwork, etc. High velocity tubing deteriorates more often than metal ducts and tubing causes stress on the mechanical components of the unit.

On the plus side, conventional systems are more visible in the home than the high velocity. Conventional systems require more space because of the larger vents, and every room needs a supply and return. The high velocity unit requires much less space and can be set up in one area for the supply and return requirements. Also, the high velocity system is less expensive than the conventional one.

Finally, keep in mind that central cooling systems are not easy to install. There is generally a problem with any installation. Any errors in installation can cause major problems and a major impact on your electric bill. Make sure you get plenty of bids and pick a contractor that you have faith in. The contractor should be experienced and offer you references to check out the work that has been done.

Air Conditioner Thermostats

A thermostat is an apparatus for maintaining the temperature of a system within a particular range by directly or indirectly controlling the flow of heat energy into or out of the system. All air conditioners have thermostats that can be manually operated or automatically preprogrammed to work at regulating the room temperature. There are many ways in which you can use an air conditioner thermostat effectively.

One of the most successful yet economical ways to reduce your air conditioning costs is to adjust the thermostat setting on the air conditioner. The savings are more noteworthy when you set your thermostat at 78 degrees Fahrenheit or higher. For each degree you raise the thermostat setting, you reduce seasonal cooling costs by 7 percent to 10 percent. In doing so, you can use ceiling fans in addition to the air conditioner and thus, save a lot of money.

Most centrally located air conditioner thermostats are equipped with two fan settings, 'on' and 'auto'. When the thermostat setting is set to 'on' the fan runs constantly and when it is set to 'auto' the fan runs only during cooling cycles when the air conditioner compressor is in use. When the air conditioner is in use all day, the cooling compressor only operates about 50 percent of the time, that is, for about 12 hours. The extra fan operating time that occurs when the thermostat is set to 'on' can add roughly $25 to monthly air conditioning bills. Using the 'auto' setting, alternatively, saves energy and money because the fan operates fewer hours. Besides achieving energy and cost savings, the 'auto' setting also promotes more comfort by offering better humidity control as moisture removed during the cooling cycle is re-circulated back into the home while the compressor is off.

Thus, thermostats play an important role in the cost and function of an AC.

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.

A Cars HVAC System

Not only do we depend on our cars to get us where we want to go, we also depend on them to get us there without discomfort. We expect the heater to keep us warm when it's cold outside, and the air conditioning system to keep us cool when it's hot.
We get heat from the heater core, sort of a secondary radiator, which is part of the car's cooling system. We get air conditioning from the car's elaborate air conditioning system.
Despite its relatively small size, the cooling system has to deal with an enormous amount of heat to protect the engine from friction and the heat of combustion. The cooling system has to remove about 6,000 BTU of heat per minute. This is a lot more heat than we need to heat a large home in cold weather. It's good to know that some of this heat can be put to the useful purpose of keeping us warm.
Air conditioning makes driving much more comfortable in hot weather. Your car's air conditioner cleans and dehumidifies (removes excess moisture), the outside air entering your car. It also has the task of keeping the air at the temperature you select. These are all big jobs. How do our cars keep our "riding environment" the way we like it?
Most people think the air conditioning system's job is to add "cold" air to the interior of the car. Actually, there is no such thing as "cold," just an absence of heat, or less heat than our bodies are comfortable with. The job of the air conditioning system is really to remove the heat that makes us uncomfortable, and returns the air to the car's interior in a "un-heated" condition. Air conditioning, or cooling, is really a process of removing heat from an object (like air).
A compressor circulates a liquid refrigerant called Refrigerant-12 (we tend to call it "Freon," a trade name, the way we call copy machines "Xerox" machines). The compressor moves the Refrigerant-12 from an evaporator, through a condenser and expansion valve, right back to the evaporator. The evaporator is right in front of a fan that pulls the hot, humid air out of the car's interior. The refrigerant makes the hot air's moisture condense into drops of water, removing the heat from the air. Once the water is removed, the "cool" air is sent back into the car's interior. Aaaaaah! Much better. Newer cars have R-134 as the refrigerant, but work in the same way as R-12.
Sometimes we worry when we catch our car making a water puddle on the ground, but are relieved to discover that it's only water dripping from the air conditioning system's condenser (no color, no smell, and it dries!).
Note: Refrigerant is extremely dangerous. Many special precautions must be taken when it is present. It can freeze whatever it contacts (including your eyes), it is heavier than air and can suffocate you, and it produces a poisonous gas when it comes in contact with an open flame.

Common Problems:

From time to time the A/C system needs to be recharged to bring it back up to maximum efficiency. Sometimes a leak may cause loss of refrigerant and will need to be fixed before refilling. It's difficult to tell if a leak is present without specific test equipment so let it up to a professional.
Corrosion will cause the heater core (secondary radiator) to leak. This will manifest itself by leaving steam into the passenger compartment and fogging your windows. You will know there is a leak by the sweet smell coming from your vents. Unfortunately changing the heater core is usually not the easier job in the world, as engineers tend to squeeze them into some pretty tight spaces under the dash.
