How a Dirty or Blocked Condenser Effects System Efficiency
One of the main components of any refrigeration or air conditioning system is the condenser. It is larger than the evaporator is because it not only has to reject the evaporator’s heat load, but also any superheat absorbed at the tail end of the evaporator and/or suction line. The condenser also has to reject the thermal energy the compressor puts into compressing the suction vapors to discharge vapors. This is often referred to as the heat of compression or work of compression.
As its name states, one of the main functions of the condenser is to condense the refrigerant sent to it from the compressor. However, the condenser also has other functions. Desuperheating and subcooling are other important functions of the condenser.
