Refrigeration, heating and air conditioning system for vehicles

Claim 1

A system structured and dimensioned for incorporation into a motorized vehicle for air conditioning a passenger compartment of said vehicle comprising: (a) a generator heated by heat of waste gases passing through an exhaust conduit, said generator contains a mixture of two intermiscible components consisting essentially of a first more volatile component selected from the group consisting of methyl alcohol, ethyl alcohol, ammonia, acetone, ethyl acetate, methyl acetate, methyl acetate-water azeotrope, tetrahydrofuran and mixtures thereof, and a second less volatile component selected from the group consisting of NaSCN, ZnCl 2 , LiBr, LiNO 3 and mixtures thereof, said more volatile first component producing vapor when heated in said generator, said vapor serving as a refrigerant, and a concentrated solution of said less volatile second component in said more volatile first component serving as an absorbent for said vapor; (b) means for transporting said refrigerant vapor from said generator to a condenser, wherein said refrigerant vapor condenses to provide a heating effect; (c) means for transporting said condensed refrigerant from said condenser via a pressure reducing means to an evaporator, wherein said refrigerant expands to a vapor to provide a cooling effect; (d) means for transporting said refrigerant vapor from said evaporator to an absorber, and means for transporting said absorbent from said generator to said absorber, wherein said absorbent absorbs said refrigerant vapor to produce an absorbent-refrigerant mixture and provide a heating effect; (e) means for transporting said absorbent-refrigerant mixture from said absorber back to said generator; (f) means for subjecting air to the heating effect provided by said absorber and said condenser to cool said absorber and said condenser and to obtain heated air; (g) means for subjecting air to the cooling effect provided by said evaporator to obtain cooled air; (h) means for mixing proportions of said cooled air and said heated air to obtain a conditioned air of a desired temperature and supplying said conditioned air to the passenger compartment; (i) at least one heat pipe structured and dimensioned for interconnection between said generator and said exhaust conduit, said heat pipe having an evaporator section and a condenser section; (j) said evaporator section being structured and dimensioned for insertion into an internal receiving portion of said exhaust conduit to contact and extract heat from said waste gases flowing through said receiving portion; (k) a transfer medium for transferring heat from said evaporator section to said condenser section; and (l) said condenser section being structured and dimensioned for insertion into said generator to contact and distribute heat to the absorbent-refrigerant mixture.

Claim 2

A system structured and dimensioned for incorporation into a motorized vehicle for air conditioning a passenger compartment of said vehicle comprising: (a) a generator heated by heat of waste gases passing through an exhaust conduit, said generator contains a mixture of two intermiscible components consisting essentially of a first more volatile component selected from the group consisting of methyl alcohol, ethyl alcohol, ammonia, acetone, ethyl acetate, methyl acetate, methyl acetate-water azeotrope, tetrahydrofuran and mixtures thereof, and a second less volatile component selected from the group consisting of NaSCN, ZnCl 2 , LiBr, LiNO 3 and mixtures thereof, said more volatile first component producing vapor when heated in said generator, said vapor serving as a refrigerant, and a concentrated solution of said less volatile second component in said more volatile first component serving as an absorbent for said vapor; (b) means for transporting said refrigerant vapor from said generator to a condenser, wherein said refrigerant vapor condenses to provide a heating effect; (c) means for transporting said condensed refrigerant from said condenser via a pressure reducing means to an evaporator, wherein said refrigerant expands to a vapor to provide a cooling effect; (d) means for transporting said refrigerant vapor from said evaporator to an absorber, and means for transporting said absorbent from said generator to said absorber, wherein said absorbent absorbs said refrigerant vapor to produce an absorbent-refrigerant mixture and provide a heating effect; (e) means for transporting said absorbent-refrigerant mixture from said absorber back to said generator; (f) means for subjecting air to the heating effect provided by said absorber and said condenser to cool said absorber and said condenser and to obtain heated air; (g) means for subjecting air to the cooling effect provided by said evaporator to obtain cooled air; (h) means for mixing proportions of said cooled air and said heated air to obtain a conditioned air of a desired temperature and supplying said conditioned air to the passenger compartment; (i) at least one heat pipe structured and dimensioned for interconnection between said generator and said exhaust conduit, said heat pipe having an evaporator section and a condenser section; (j) said evaporator section being structured and dimensioned for insertion into an internal receiving portion of said exhaust conduit to contact and extract heat from said waste gases flowing through said receiving portion; (k) a transfer medium for transferring heat from said evaporator section to said condenser section; and (l) said condenser section being structured and dimensioned for insertion into said generator to contact and distribute heat to the absorbent-refrigerant mixture.
