A compression refrigeration system having means to pass the low pressure gas from the evaporator in heat exchange relationship with the high pressure liquid passing from the condenser to the expansion valve. The low pressure gas is passed in heat exchange relationship around the external casing of the receiver/drier, to maintain the receiver/drier at a lower temperature, assist in ensuring that the low pressure gas does not contain any unvaporized liquid, and to cool the high pressure liquid before passage to the expansion valve.
