Patent ID: 8643202

Claim:
An air conditioning system comprising: an air conditioning unit including an expansion valve, an evaporator coupled to said expansion valve, a compressor coupled to said evaporator, and a condenser coupled between said compressor and said expansion valve, wherein said expansion valve, said evaporator, said compressor and said condenser cooperate to form a first coolant circulating loop for circulation of a first coolant; and an electricity generating unit including a heat radiator disposed adjacent to said evaporator, a heat absorber coupled to said heat radiator and disposed adjacent to said condenser, a turbine coupled between said heat radiator and said heat absorber, and an electricity generator coupled to said turbine, wherein said heat radiator, said heat absorber and said turbine cooperate to form a second coolant circulating loop for circulation of a second coolant, said turbine generating mechanical energy from flow of the second coolant through said turbine, said electricity generator converting the mechanical energy from said turbine into electricity.
