Abstract:
1. An apparatus for temperature adjustment comprising (a) an absorber that forms a mixture of a mixture of a refrigerant and an absorbent; (b) a generator that receives the mixture from the absorber and heats the mixture to separate refrigerant, in vapor form, from the absorbent, and increases the pressure of the refrigerant vapor; (c) a condenser that receives the vapor from the generator and condenses the vapor under pressure to a liquid; (d) a pressure reduction device through which the liquid refrigerant leaving the condenser passes to reduce the pressure of the liquid to form a mixture of liquid and vapor refrigerant; (e) an evaporator that receives the mixture of liquid and vapor refrigerant that passes through the pressure reduction device to evaporate the remaining liquid to form first and second portions of refrigerant vapor; (f) a compressor that receives the first portion of the refrigerant vapor, increases the pressure thereof, and passes the first portion of the refrigerant vapor to the condenser; and (g) a conduit that passes the second portion of the refrigerant vapor leaving the evaporator to the absorber; wherein the absorbent comprises one or more ionic liquids; and wherein the refrigerant is selected from one or more members of the group consisting of hydrofluorocarbons, N
