The American standard air conditioner is one of the leading brands of air conditioners that are available in the market. The American brand air conditioner is well known for its top notch quality and service.

The air conditioner from the American standard company is very reliable and comfortable to the customers. There are several advantages in buying an American standard air conditioner. One of the major advantages is the fact that it lets the customer stay cool and it also helps in saving a lot of money with his efficient usage of current.

There are several American standard models available on the market. These models vary with respect to the SEER value. SEER is nothing but the Seasonal Energy Efficiency Ratio.

It is the ratio or the rating that is used to measure the efficiency of cooling factor of a specific heat pump or an air conditioner.

If the seasonal energy efficiency ratio is higher then the efficiency of the air conditioner is also higher and vice versa. So it is always better to buy an air conditioner with a higher SEER value.

The American standard air conditioner ranges in the efficiency factor from the SEER value of 13 to the SEER value of more than 18. This SEER value for the American brand air conditioner is among the best that is available in the market. The American standard air conditioner has the highest rating for efficiency in the air conditioner industry.

Because of this factor a lot of customers usually buy the American standard. There are several choices to choose from. One of the best models is the allegiance American standard air conditioners. If you want the best, I recommend getting the Allergiance 18 which has maximum efficiency and cooling.

There are so many choices are comfort that is available to the customer to choose from. There are several technological factors also that come in to consideration while buying the air conditioning unit.

The American standard air conditioner gives you the comfort of cooling that the customer always looks for in his home. It is thus a very effective air conditioner unit with the latest technologies.

From:http://www.apparatus-instrument.com/

Air conditioners and refrigerators work the same way. Instead of cooling just the small, insulated space inside of a refrigerator, an air conditioner cools a room, a whole house, or an entire business.

Air conditioners use chemicals that easily convert from a gas to a liquid and back again. This chemical is used to transfer heat from the air inside of a home to the outside air.

The machine has three main parts. They are a compressor, a condenser and an evaporator. The compressor and condenser are usually located on the outside air portion of the air conditioner. The evaporator is located on the inside the house, sometimes as part of a furnace. That’s the part that heats your house.

The working fluid arrives at the compressor as a cool, low-pressure gas. The compressor squeezes the fluid. This packs the molecule of the fluid closer together. The closer the molecules are together, the higher its energy and its temperature.

The working fluid leaves the compressor as a hot, high pressure gas and flows into the condenser. If you looked at the air conditioner part outside a house, look for the part that has metal fins all around. The fins act just like a radiator in a car and helps the heat go away, or dissipate, more quickly.

When the working fluid leaves the condenser, its temperature is much cooler and it has changed from a gas to a liquid under high pressure. The liquid goes into the evaporator through a very tiny, narrow hole. On the other side, the liquid’s pressure drops. When it does it begins to evaporate into a gas.

As the liquid changes to gas and evaporates, it extracts heat from the air around it. The heat in the air is needed to separate the molecules of the fluid from a liquid to a gas.

The evaporator also has metal fins to help in exchange the thermal energy with the surrounding air.

By the time the working fluid leaves the evaporator, it is a cool, low pressure gas. It then returns to the compressor to begin its trip all over again.

Connected to the evaporator is a fan that circulates the air inside the house to blow across the evaporator fins. Hot air is lighter than cold air, so the hot air in the room rises to the top of a room.

There is a vent there where air is sucked into the air conditioner and goes down ducts. The hot air is used to cool the gas in the evaporator. As the heat is removed from the air, the air is cooled. It is then blown into the house through other ducts usually at the floor level.

This continues over and over and over until the room reaches the temperature you want the room cooled to. The thermostat senses that the temperature has reached the right setting and turns off the air conditioner. As the room warms up, the thermostat turns the air conditioner back on until the room reaches the temperature.

jveryrad asked:


I have a new central air conditioner. Normally, it cools down the house 5 min per degree, so it takes around 25 min to lower the temperature from 80 to 75 degrees upstairs. I have 2 floors. Today, I went out to run errands and didn’t get back until 1pm, when it became 91 degrees outside and 85 degrees inside. I kept the AC on for several hours, and it didn’t cool the house below 78 degrees until 9pm.

Does the AC work less effectively when it’s really hot outside, and the coils don’t cool off very fast in 90 degree heat? Is that why it didn’t go below 78 degrees inside till night time?

Is there such as thing as a super-hot day when even a 3.5 ton AC gets overwhelmed? Is there any point to “staying ahead” by turning the AC on at 11am if we think a hot one is coming in order to start cooling earlier before the house gets really hot?

schneiderbs asked:


I have water in my basement. I am trying to determine the source. Two possibilites: my foundation or my piping coming from my air conditioner. I have a theory that there may be a leak in the piping coming from the air conditioning unit causing water in the basement. I do not have a lot, probably about two gallons every day. Is it possible it is coming from my air conditioner?

Whats the best way to winterize a window air conditioner?
Also what is the purpose of winterizing? Is it to keep cold air out? Or does it protect the air conditioner itself?
Thanks for the info.

I live in Japan, and my air conditioner hasn’t been heating very well recently. Sometimes it shuts off by itself, but today, it just hasn’t been giving warm air. I have a feeling that the filter needs to be replaced. It’s a rather standard wall mounted air conditioner made by Mitsubishi that is common in Japanese apartments. Any ideas?

Since the days Willis Carrier introduced us to the device of air conditioners to the present, the device has pervaded almost all aspects of our life. They can be found in almost all facets of our life. From our bedroom, to our office, from the schools our children go to, to the malls we go for our shopping. It is everywhere we look at. This would make us wonder how wide ranging would be the applications of air conditioners.

The indoor and outdoor units of a ductless air conditioner are linked with a conduit. Within the conduit is the power cable, refrigerant tubing, suction tubing, and condensate drain. While the compressor which creates a whole lot of noise is in the outdoor unit, the quieter parts of the air conditioner – the fan and the evaporator are in the indoor unit.

If you ask an expert like an air conditioner engineer as to what are the applications of the device he would answer that it can be divided into two broad categories: – Comfort and – Process

When an air conditioner is meant for comfort applications its main job would be to provide a constant temperature indoors whatever may be the fluctuations of weather outside. It would also be able to deal with any change of temperature due to internal heat loads. The temperature maintained by these air conditioners is in the range where humans feel comfortable as these air conditioners are manufactured to provide comfort to humans.

Comfort air conditioners have allowed humans to build deep buildings where otherwise you wouldn’t have fresh air flowing in. The only way out was by building light wells. But with a central air conditioner in place you can actually cover as much horizontal floor space as you want and need not worry about ventilation. Air conditioners have also allowed humans to build extremely tall buildings. With air turbulence unpredictable at extreme heights, ventilating high rises would not have been feasible. With air conditioners one can do away with that problem.

Comfort air conditioners are again of two types – for residential buildings and for commercial buildings.

Process air conditioning is meant to maintain a constant temperature irrespective of the weather outside or the internal heat loads. However, even under process air conditioning the temperature is generally within the comfort range. But it must be understood that in process air conditioning it is the process and not what you and I prefer that would determine the temperature that is maintained.

When an open heart surgery is performed the temperature maintained is about 18 degree Celsius or 64 degree Fahrenheit. For a neonatal operation again the temperature maintained is pretty higher – something around 28 degree Celsius or 82 degree Fahrenheit.

So the applications are pretty wide ranging.

No matter what kind of car or how old, it will start to stink if you use the air conditioner. What causes this? How do you prevent it or get rid of it?

Stephen Haworth asked:


Did you know that an air conditioning unit can omit 1.34lbs of carbon dioxide for every kilowatt hour used? By replacing older air conditioning units you could save several hundreds of pounds of carbon dioxide being released into the atmosphere each summer season. This will not only save the environment but also save you some green as well. You can save as much as $65 using a newer air conditioning unit verses an older air conditioning unit.

When you are looking for a new air conditioning unit you will need to first look for the proper size unit for your living space. The amount of space an air conditioning unit cools is measured in BTU’s. BTU’s stands for British Thermal Units. When you are looking for an air conditioning unit you will first need to decide the number of BTU’s that the air conditioner will need to cool your living space. You can calculate the required BTU’s by multiplying the square footage of the space by 10. You will then need to add 4,000 to that number. By choosing the proper size air conditioner for the space it will allow you to conserve energy. If you choose an air conditioner too large for the area or too small for the area then you will be causing unneeded drain on your electricity.

When looking for a new air conditioner unit you will also want to shop for one with an energy star approval on it. Energy Star approval is a label given to a product by the Environmental Protection Agency. This insures that the product is 10 percent more efficient than what is required by the minimum federal standards.

You will also want to look for a unit that can dehumidify the air as well if you live in a humid climate. By using an air conditioner that dehumidifies the air you will be able to make the environment more comfortable by reducing the humidity. This will allow you to keep the air conditioner at a lower setting and still feel comfortable.

You can also be eco friendly when using your new air conditioner as well. Use your air conditioner wisely to reduce electric bills as well as reducing the CO2 emissions caused by the use of electricity. By setting your air conditioner to a lower setting making it comparable to the temperatures outdoors rather than what you want it to feel like. This will make going outdoors during the summer months more enjoyable as well. Use the fan only option on the air conditioner at night to reduce the amount of electricity you use.

Many air conditioners also come with a recirculation option. This allows the air that has already been cooled to be recirculated around your home. You should have your air conditioning unit properly installed and sealed around the area to ensure you do not have cool air leaking outside. Finally be sure to clean and check the filters on your air conditioning unit regularly. Many air conditioners only need to be cleaned every 3 months but depending on the area you live in you may need to clean it as often as every month. This will help keep your air conditioning running more efficiently as well as keep you and your family more healthy.

Keeping you home cool during the summer can be a life safer but can also be dangerous on the environment. By keeping energy cost low and using the most efficient units possible you can not only save money on energy cost but also save the environment while keeping cool. Be sure to recycle your old air conditioning units. There are even some governments that will give rebates for old air conditioning units that are turned in.This program can save you as much as $75 per unit you replace.

If you live in an area of the country where it gets extraordinarily hot during the summer months, you know that air conditioning is crucial to your comfort. Air conditioning can also prove very useful in rooms that contain computer equipment, such as servers, in order to keep all of the electrical equipment cooled off so that it continues to function properly. It can be costly to install and then run a permanently mounted air conditioner, yet a portable room air conditioner provides an efficient solution for your seasonal cooling needs.

One benefit you will receive from using a portable room air conditioner is that you can position it exactly where you need it. Because it moves on smooth-rolling casters, it is a simple matter to change its position to the best advantage around your home or office. For example, a portable air conditioner can help you start your day with pleasant cool air in your kitchen along with your first cup of coffee. Kitchens typically get rather hot with stoves and dishwashers going, and can be unpleasant to work in. Bring the pleasure back with a portable room air conditioner that cools your kitchen off so you can cook in comfort.

It can be costly using a permanent air conditioner because it tends to work on an entire floor of a house or building, so you have to cool the entire area whether you are using particular rooms or not in order to get the benefit where you need it. Not so with a portable room air conditioner. Because it can be positioned exactly where you need the cool air, you will save money by not cooling other areas that will not benefit from the cooling. A computer room, holding your all-important server, requires fans and air conditioners that will be on and working when the servers and computers are working, in order to keep everything performing at optimal levels without melting down electrical components. A portable air conditioner can be focused where the cool air will be most useful, and thus will save you money by not expanding the cooling effect to where it is not needed.

You simply pay for what you use when it comes to portable room air conditioners. Because when the weather warms up we often spread our living spaces to the outdoors, a portable room air conditioner can be used to great effect in covered outdoor situations as well. Your screened porch just got a new lease on life, because you can keep it enjoyable at just the right temperature level. A portable room air conditioner is your efficient way to cool just the areas you need, when you need it.
