REGENERATIVE REFRIGERATION SYSTEM WITH MIXED REFRIGERANTS

摘要

A regenerative type of refrigeration system recirculates a mixture of R-134a, R-32 and R-125 through first and second series condensers (14A, 14B). A first vortex tube (50) is connected to the inlet of the first condenser (14A) and a second vortex tube (51) is connected at the outlet of the first condenser (14A) to provide a vapor path (19) from a compressor through the condensers to an expansion device and evaporator. The liquid inlet of a first vortex tube (50) and a liquid outlet of a second vortex tube (51) are connected together to define a closed recirculation path (55) around the first condenser (14A) for liquified R-134a.
