Operating principles

The fluid refrigerant at the outlet of a condenser is usually collected in a liquid receiving tank, in which the liquid and vapour phases coexist. The temperature of the condensate at the outlet of the liquid receiving tank is therefore at a temperature which coincides with the condensation temperature, excluding the effects induced by the pressure drop which the refrigerant undergoes while passing through the condenser.

Advantages of subcooling

Subcooling the liquid condensate before expanding it and running it to the evaporator enables increased refrigerating power and increased energy efficiency to be achieved. All the heat given up to the environment during the subcooling phase is reintroduced into the refrigeration cycle as useful work (free, from the point of view of energy consumption) in the evaporation phase. An additional advantage of subcooling is the possibility of permitting pressure drops in the line which takes the refrigerant from the condenser to the expansion valve without the formation of vapours.
