The Essentials

Your air conditioner is made up of four main elements:

Refrigerant: a chemical that collects & absorbs heat.
Compressor: powerful pump that circulates & compresses refrigerant.
Condenser: cools down/condenses hot vapors coming from compressor.
Evaporator: converts refrigerant liquid into gas.

These basic parts work together to absorb and expel heat in a systematic fashion; extracting hot air through a series of steps that eventually loop back cooler air temperatures. Let’s delve further…

Time to Cool Down

The cooling down process begins when your thermostat, a sensor that detects the temperature in your home, calls for cool.

  • Sending Signals: Your thermostat signals the compressor to start circulating the refrigerant throughout the system.
  • Motor Activate: Simultaneously, the blower motor (located inside your furnace) is activated; pushing the air within your house through the evaporator.
  • Chemical Absorption: As air passes through the evaporator, the refrigerant absorbs and extracts its heat.
  • Heat Be-Gone: At this phase, your condenser expels the collected heat from inside your home, and releases it outdoors. Your A/C continues to expel heat until the thermostat detects the desired temperature has been reached. It then cuts off power to the blower motor and compressor.
  • Cycling Process: As the temperature gradually begins to rise, the thermostat will once again call for the process to repeat. This cycling ensures that your home always stays cool and comfortable.

Final Thoughts

In recent years, air conditioners have become an essential appliance to beat the heat during summertime months. Fitted for both home and vehicular use, air cons are the answer to keeping cool when you’re stationary, or on-the-go. Now that you know just how your A/C works, be appreciative of its power to offer respite, even in spite of the summer swelter!
