APPARATUS FOR EXPANDING THE TEMPERATURE GLIDE OF A NON-AZEOTROPIC WORKING FLUID MIXTURE IN A VAPOR COMPRESSION CYCLE

摘要

vapor compression refrigeration device using a mixture of working fluids with non-azeotropic separation of the liquid mixture and the vapor mixture. The separation can take place at an elevated pressure during the condensation to increase the temperature glide, at low pressure for the condensation, or both during evaporation and condensation. When separation occurs during the condensation, the number of stages in the evaporator (41) and condenser (20) should be equal.
