What is an Air Source Air Conditioner?

You’ve probably heard that an air conditioner works on the same principle as a refrigerator, using the warm air outside to keep the air inside nice and cool. And while this is correct, it assumes you know how a refrigerator actually works. Without getting too technical, there’s one thing to understand about thermodynamics: Heat wants to share its warmth. When there are two different materials, the heat from the warmer element will transfer to the cooler item. This is the magic that makes air conditioners an essential part of living in the tropical paradise of the Cayman Islands.

Air Conditioning 101

1. When you turn on your air conditioner, a pump starts to circulate a refrigerant (the gas enclosed in your close-looped system)
2. The refrigerant is forced through a tiny nozzle to release pressure. This rapid expansion causes the temperature of the refrigerant to drop quickly. If you’ve ever used an aerosol spray, you probably noticed the can gets colder as you spray the contents. This happens within your AC system as well.
3. This liquid is pumped through a radiator to extract the heat from your home for transfer elsewhere.
4. The refrigerant then passes through a compressor, where intense pressure is used to convert it to a liquid – a very hot liquid – that passes through another radiator that allows the heat energy to escape outside(to the air for an air source system or to the ground in a geothermal setup)
5. The refrigerant is then pumped back through the system, and the cycle repeats until your home is at the desired temperature
Your AC system may also have ducts to transport the cooled air to the rooms you want to cool; a blower to move the air in the right direction; and a thermostat to act as the brains for the system so you don’t get too cold or too hot.
