The compressor in your outdoor unit compresses the refrigerant (or "Freon") by transferring the part of the electrical energy it consumes into a high-temperature, high-pressure gas. Frigiquip Strato Dawn in early model US Ford. They also have a On its journey around the system it has three main stages; the evaporator contains the sub-cooled refrigerant and air blows through its veins to release the chilled dry air into the room, the condenser contains the high temperature gas that once again air is blown through the veins collecting the heat as it passes through and this is then expelled outside. Willis Carrier invented the air conditioner, and Carrier residential AC units set the standard for modern, precision air conditioners. In a way, if you know how an air conditioner works, then you already know a lot about how a heat pump works. The cold side, consisting of the expansion valve and the cold coil, is generally placed into a furnace or some other air handler. Here's one of his early designs—and note how closely it resembles my quick sketch up above. So only the heat is transferred to the outside, not the air. exchanger with cool water circulating in the opposite direction. Back in the 1930s it was Packard that became the first car maker to install an air-conditioning unit which was called a Weather Conditioner. How air conditioning works The essential ingredients in an air conditioning system are a fan to blow air around, a cold surface to cool and dehumidify the air, a warm surface and a source of water vapour.
