Malnar, D

In a refrigeration apparatus comprising a circuit for a refrigerant fluid having an evaporator, a compressor for compressing the evaporated refrigerant fluid and a condenser for causing condensation of the compressed fluid, the condenser is described comprising a pipe having an inlet end and an outlet end, means on the inlet end for injecting fluid in gaseous phase under pressure into the pipe for condensation within the pipe to form a liquid phase, and means at the outlet end for receiving the condensed liquid phase. An outer surface of the pipe is arranged to engage a coolant fluid for cooling the outer surface and the fluid within the pipe. The pipe extends continuously from the inlet end to the outlet end and has a substantially constant cross-section area therealong and is shaped by bending to form pipe portions. Junction portions connect respective ends of one of the pipe portions to a next adjacent pipe portion. Each of the junction portions define a path which extends solely between the respective one of the pipe portions and the adjacent pipe portion and which includes a part thereof which extends to a height above both the respective one of the pipe portions and adjacent pipe portion so as to form a liquid trap.
