An AC condenser, or simply a condenser, is the outdoor component of an air conditioner or heat pump that either releases or collects heat, depending on the time of the year. It is a vital component of all AC units and is designed to help with the process of efficient heat transfer. The condenser coil is a critical part of the condenser unit and can be made of copper tubing with aluminum fins or all-aluminum tubing so heat can be rapidly transferred. The compressor is another essential part of the condenser unit, and it pumps refrigerant into the condenser coil in the form of hot gas. The condenser fan is responsible for circulating the air across the coil to facilitate heat transfer. The primary function of the condenser is to assist with heat transfer, which is accomplished by condensing a gaseous refrigerant until it is super-heated and then passing it through a system of coils to cool. The AC condenser unit is filled with refrigerant gas, a chemical that traps and moves heat throughout an air conditioner system. The condenser is responsible for the condensation process in an AC unit, which helps efficiently disperse latent heat through the phase shift of refrigerants inside of the condenser coils.
