Abstract:
1. An air conditioning system comprising: a primary circuit including a compressor, a first heat exchanger for heat transmission from a refrigerant to the environment, a first throttling element, and a second heat exchanger for heat transmission to the refrigerant from air to be supplied to a passenger compartment, wherein the primary circuit includes a first segment extending from an outlet end of the compressor to the first heat exchanger, a second segment extending from the first heat exchanger to the second heat exchanger, and a third segment extending from the second heat exchanger to an inlet end of the compressor, wherein the first segment, the second segment, and the third segment are all separate and distinct from each other; a first secondary circuit portion extending from the primary circuit at a first branch point and reentering the primary circuit at a first entering point, wherein the first branch point is disposed on the first segment of the primary circuit and the first entering point is disposed on the third segment of the primary circuit, wherein the first secondary circuit portion includes a third heat exchanger for heat transmission from the refrigerant to air to be conditioned in the passenger compartment and a second throttling element; and a second secondary circuit portion extending from the primary circuit at a second branch point and reentering the primary circuit at a second entering point, wherein the second branch point is disposed on the first segment of the primary circuit between the first branch point and the first heat exchanger and wherein the second entering point is disposed on the third segment of the primary circuit between the first entering point and the inlet end of the compressor.
