Refrigeration System With Dual Refrigerants and Liquid Working Fluids

A refrigeration system comprising a refrigerant composition and a compression refrigeration apparatus, wherein the refrigerant composition comprises at least one gas refrigerant and a working liquid selected from the group consisting of water, alcohol, ionic liquids and mixtures thereof;

• wherein the compression refrigeration apparatus comprises:
• (a) an absorption/reaction chamber configured to receive the gas refrigerant that is passed from a compressor into the absorption/reaction chamber;
• wherein the compressor is optionally an oil-lubricated compressor or an oil-free compressor;
• (b) an evaporator/desorber chamber configured to pass an unsaturated working liquid to the absorption/reaction chamber;
• wherein the one or more gas refrigerants reversibly react in the absorption/reaction chamber under high pressure and absorbed by the unsaturated working liquid to form a saturated working liquid;
• (c) a hot side heat exchanger configured to be connected to the absorption/reaction chamber, where heat is removed from the refrigeration composition;
• (d) a pressure reduction device configured to receive the saturated working liquid from the absorption/reaction chamber and to pass the saturated working liquid to the evaporator/desorption chamber;
• wherein the pressure reduction device comprise a valve or a capillary tube;
• wherein the gas refrigerant vaporizes from the saturated working liquid under low pressure in the evaporator/desorption chamber to form the unsaturated working liquid;
• (e) a cold side heat exchanger configured to be connected to the evaporator/desorption chamber, where heat is absorbed by the refrigeration composition;
• and
• (f) a conduit configured to receive the gas refrigerant from the evaporator/desorption chamber and to return the gas refrigerant to the compressor.
