How Does an Air Conditioner Work?

The temperatures are hitting record highs throughout the U.S. and the majority of homes are running some type of air conditioner to beat the summer heat. Although we are all grateful that your air conditioner works, the experts at Kyzar Air Conditioning Inc in West Palm Beach would like to tell you how it works.

The Basics

There’s plenty of science regarding keeping your living space cooler. Your air conditioner runs in a similar way to your refrigerator, of course your cooling system has a bigger task to manage. Both your fridge and AC cool with a reoccurring loop of refrigerant, with your AC this refrigerant loops from inside to to the external part of your home. This refrigerant effortlessly changes from a liquid to gas and back to a liquid again. It flows into your residence as a sub-cooled liquid and as it evaporates it absorbs heat from inside the home and reverts back into vapor. This vapor then moves back to the unit located outdoors where the heat is freed and is then condensed back into a sub-cooled liquid.

Four Components

There are 4 core components to your AC system: a compressor, an evaporator coil, the condensing coil and an expansion valve.

The evaporator coil is the place your refrigerant evaporates from a sub-cooled liquid into a super-heated vapor. This component can be located in the home, in your garage or even in your attic. Warm air passes through the cold evaporator coil and the heat is taken from the air. This cooled air is then transferred throughout your home.

Your compressor is located in your outdoor condensing unit. The super-heated vapor from your evaporator coil goes into the compressor which raises the pressure of the vapor until it is transformed into hot, high pressure vapor. The hot vapor then moves back into the condenser coil where less hot outdoor air moves across the coil, heat is released outdoors and the refrigerant is changed back into a sub-cooled liquid. This sub-cooled liquid is then returned to the indoor evaporator coil by an expansion valve or metering device. This continues repeatedly throughout the process.

That accomplishes your physics lesson for now…your air conditioner operates on an never-ending loop of science. We realize that it’s not as crucial to you how it works, but just the fact it’s running. If you’d like to discuss staying cool and comfortable in West Palm Beach give us a call at 561-612-0242.
