How Is Heat Being Removed Through Air Conditioning?


Air conditioning is the process of removing heat from a room or space. The cooling process occurs when a refrigerant is compressed, which causes it to boil and turn into a gas. The gaseous refrigerant then passes through an evaporator coil that absorbs the heat in the air. Afterward, the cool gas flows through an expansion valve, releasing it into the atmosphere.

Some Distinct Functions Performed by Your AC to Remove Heat:

  • Absorption of heat by Evaporator Coil: The evaporator is responsible for absorbing and removing the heat from the air. Turning on your unit cools the evaporator coil by compressing a liquid refrigerant into a vapor. This creates a cold liquid that absorbs heat from your home’s interior. Once this liquid reaches its boiling point, it turns back into a liquid and releases its absorbed heat outside your home.
  • Rise in the Refrigerant Temperature by Compressor: The refrigerant absorbs heat from the indoor air and gets heated up. This process is called “compression,” It happens in a compressor. The compressor converts the gas into liquid form and vice versa. Furthermore, the refrigerant gas is compressed into liquid form to move more quickly through the system. The more this process takes place, the more efficient it becomes for your AC to remove excess heat from your home or office.
  • Removing Moisture: Most homes have constant humidity due to evaporation from showers, cooking, and laundry. When warm, dry air enters an AC system with humid outside air, condensation occurs on all surfaces, including pipes and equipment. This condensed water can cause damage to equipment if left unchecked and is usually removed using a drain pan located behind the evaporator coil, which collects water from inside your home during the summer months.
  • Removing Excess Heat: Your AC uses refrigerant to remove heat inside your home. This refrigerant passes through coils connected to a compressor in the outdoor unit. The compressor squeezes the refrigerant so that it becomes freezing. The cold refrigerant is then sent to the indoor unit, which circulates through the air handler or blower assembly. The air handler blows out cool air throughout your home, removing heat from your home as it passes over the coil in the outdoor unit.
