Air Conditioning FAQ: What Is the Compressor?

There are many different types of air conditioners on the market today, from high-efficiency heat pumps to ductless units to the traditional split-system AC. What’s interesting is that although units vary greatly in size, efficiency, and performance, most use the same components to operate. A condenser coil, expansion valve, and condenser coil are all necessary for the refrigeration process, as are a chemical blend called refrigerant, a couple of fans, and one of the most important components—the compressor.

Learn about the compressor’s role in refrigeration in today’s guide. And call the experts at Envirotech Air Quality Services if you notice trouble with your air conditioning in Lake Worth.

The goal of refrigeration is to remove heat from a space. Refrigerant is a chemical blend that can easily convert from a liquid to a gas and back again under the right conditions. During the evaporation process, refrigerant can absorb heat, and during condensation, refrigerant gives off heat to the outdoors. This occurs in the inside evaporator and outside condenser coils, respectively, and it also undergoes pressure changes in the process.

The component that gives refrigerant enough pressure that it can pump through the entire system and properly carry through with the process is the compressor. The compressor is a motorized component that pumps refrigerant throughout both portions of the system. This part is located outside and pressurizes refrigerant as it leaves the evaporator coil, and before it reaches the condenser coil.

Refrigerant enters the compressor as a relatively cool gas at a low pressure. It adds pressure by compressing the gas, essentially squeezing it—in a sense—to reduce the volume. This adds temperature as well, so that refrigerant can give off its heat at the condenser coil.

There are a few problems that may occur with a compressor. This is one of the most important components, and when it fails you may need to replace your outdoor unit entirely. Refrigerant leaks, dirty components, and electrical trouble can all have an impact on the compressor, so call a technician for regular maintenance visits to check on the condition of your unit.

Call Envirotech Air Quality Services today and schedule an appointment for our air conditioning services in Lake Worth or to learn more about how to care for your compressor.
