The A/C: How It Works, Some Terms to Know

The hot and humid summers of Broken Arrow put quite a demand on your A/C. You can keep your air conditioning operating at its best with some basic knowledge and a plan for regular maintenance. Understanding how your air conditioning works and knowing some of the terms will help you get the most from your system.How it worksYour A/C removes heat from the air inside your home and releases it to the outside. Cool air is then circulated throughout your home. It does this by using a refrigerant that changes from liquid to gas and back to liquid. It absorbs heat as it evaporates and releases heat when it condenses.Basic components

  • Compressor: The A/C compressor is typically located outside and driven by an electric motor. It compresses the refrigerant. The high pressure packs the molecules of the refrigerant together, thereby raising its temperature and energy. This hot, high pressure vapor then goes to the condenser.

  • Condenser: The condenser is also located outside along with the compressor in what is called the condensing unit. Air blows across the condensing coils and releases heat from the gas to the outside air. As the temperature of the refrigerant lowers it becomes a liquid and is moved to the expansion valve.

  • Expansion valve: The hot liquid refrigerant becomes a mist as it passes through the tiny opening of the expansion valve. The molecules have room to expand and cool. The refrigerant is now a low pressure cool liquid and moves to the evaporator coil inside your home.

  • Evaporator coil: Warm air is cooled as it blows across the evaporator coil. The refrigerant heats up as it absorbs heat energy from the air and returns to a gaseous state. It then returns to the compressor to repeat the heat exchange process.
