Refrigerant Condensers
Vahterus heat exchangers are often installed on the high pressure side of a refrigeration or heat-pump system. The main reason for this is to reject the condensation heat as waste for refrigeration and/or to further use the rejected heat energy in heat pump systems delivering much warmer water.
In almost all applications, compressor discharge gas flows into the condenser. The NH3 discharge gas from the compressor is normally superheated 30–100°C above the condensing temperature. In condensers for refrigeration systems and heat pumps, a part of the surface is needed for the rejection of the superheat if no desuperheater is installed prior to the condensing.
