Condenser coils in air conditioning units and heat pumps (continued)

As I mentioned in my last blog, condenser coils are found in air conditioning and heat pump condensers. The condenser unit contains a compressor, a condenser coil, a fan, and assorted controls. To transfer heat rapidly, the condenser coil is typically copper tubing with aluminum fins or aluminum tubing and fins.

We’ll focus on heat pump condensers in this blog. In terms of controls, a reversing valve directs the flow of compressed gas to the condenser coil for air conditioning or to the evaporator coil for heating. Depending on the outside temperature, the condenser coil can become very cold and develop frost. If too much frost accumulates, it restricts airflow and reduces the condenser coil's efficiency. A defrost control can switch from heating to air conditioning mode automatically, melting the ice when hot gas runs through the condenser coil. The system then switches back to heating mode. To make sure the heat transfer runs smoothly, condenser coils should be kept clear of debris and dirt.
