How Air Conditioning works
How air conditioning works
On a warm summer day you want your home to be cool and comfortable and this of course requires an air conditioning system. Whether it’s central air conditioning or simply an air conditioner installed in the window or the wall, they both work very similarly.
Generally what is happening with an air conditioner is that warm air is being pulled into an air conditioning unit, cooled and returned to the room. Much like refrigerator, a compressor cools gas or refrigerant and compresses it, which in turn causes it to become warm. The warm gas then runs through some coils and during this process the gas turns into a liquid. As the liquid is forced through a valve called an expansion valve, the liquid evaporates and becomes a very cold gas which absorbs heat. This process is a continuous process and then the air in your home is made cooler as the warm air is absorbed.
Whether you have a central air system located outside or another type of air conditioner, the process works the same. The gas is often referred to as “freon” and some forms of it have been known to harm the environment, soto much care is taken by technicians when a leak is found, so that it minimizes the amount of gas that escapes.
