How Does an Air Conditioner Work?  

Many of us often take our air conditioning for granted. We don’t appreciate the mechanics of it and what exactly life would be like if Willis Carrier did not invent the modern air conditioner at the turn of the 20th century. Understanding how air conditioners work is helpful for troubleshooting any issues that may arise during operation.

Refrigerators and Air Conditioners: Different but Alike

Air conditioners work in the same way as refrigerators, just on a larger scale. Fridges are responsible for cooling a small, compact space while air conditioners can cool down large, multi-room buildings. The types of refrigerants used in the majority of air conditioning systems are R-22 and R-410A. These chemicals convert from a gas to liquid in order to remove the heat from the home.

Three Part System

Air conditioners consist of a condenser, an evaporator and a compressor. Air from the house is absorbed into the evaporator while the refrigerant located inside the system’s coils measures the amount of heat in the air and transforms the liquid into a gas. The process causes the hot air to cool down rapidly. The vapor goes into the compressor and compresses the gas to a highly pressurized state. The condenser is then responsible for returning the gas back to a liquid state with the cooled off liquid getting returned into the building. After getting pumped back into the house, the process will begin again to maintain your comfort level. A fan is attached to the evaporator to circulate the air throughout the home. Air conditioners also act as dehumidifiers since they remove moisture from the air.

Even though this may be confusing, the experts at Westberry Heating and Air can help you maintain your air conditioner for optimum comfort. Contact us today!
