Air Conditioning – How it gets cold
May 15, 2015
The hot weather is coming – we hope you have your air conditioner ready!
These units generally sit in our side yards where we don’t worry about them. We leave them to chug away, keeping us in comfort; but have you ever wondered how they do that?
Our planet has been using air conditioning in one form or another since the time of the ancient Egyptians, using palm fronds to regulate temperature. The modern air conditioning unit came into existence around the turn of the 20th Century. The first home-based unit came around in the 1930s and we have been tweaking and perfecting it ever since.
The working concept has always been essentially the same – expel heated air and circulate cooled air in its place. This is done by pulling air through the intake register and running it over coils that are filled with cooled refrigerant. The coils cool the air through heat transfer, warming the refrigerant and cooling the air. The cool air is recirculated back into the house while the refrigerant run through the compressor and subsequently cooled by the unit so that it can be used again. Any air that is heated through the process is released outside of you home, keeping the inside nice and comfortable.
We have made it our job to make sure that your air conditioner does what it’s supposed to do. One of the best ways to keep your HVAC equipment chugging is to have it serviced regularly.
