Condenser coils in air conditioning units and heat pumps
Condenser coils are found in air conditioning and heat pump condensers. The condenser unit holds a compressor, a condenser coil, a fan, and assorted controls. The condenser coil is usually made of copper tubing with aluminum fins or aluminum tubing and fins to rapidly transfer heat.In a central cooling system, the condenser unit and condenser coil are usually located outside of the building. For condensers in cooling only units, the controls are more limited than in heat pump condensers. A commonly found control is a brownout time delay that temporarily shuts the system off if the voltage drops.In heat pump condensers, 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. Too much frost restricts airflow, reducing the condenser coil's efficiency. A defrost control can automatically switch from heating to air conditioning mode, and the ice melts when hot gas runs through the condenser coil. The system then switches back to heating mode.Condenser coils can withstand a pressure of over 400 psi during hot weather. To make sure the heat transfer runs smoothly, condenser coils should be kept free of debris and dirt.When it comes time to replace your condenser coils, contact Emergent Coils for standard and custom condenser coils.
