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