Combined vapor absorption and mechanical compression cycle design
Abstract:
A refrigeration system is provided including a vapor compression cycle (20) having a condenser (22), and expansion valve (24), and evaporator (26) and a compressor (28). A refrigerant is configured to circulate through the vapor compression cycle. The refrigeration system also includes an absorption refrigeration cycle (30) having an absorber (32) and a desorbed (34) arranged in a generally closed loop configuration. An absorption solution is configured to circulate through the absorption refrigeration cycle. The vapor compression cycle and the absorption refrigeration cycle are substantially integrated. The absorber is fluidly coupled to the compressor and is configured to generate a mixture of refrigerant and absorption solution. The desorber is fluidly coupled to the condenser and is configured to separate the refrigerant from the mixture and increase a pressure of the refrigerant vapor.
