Abstract
A climate-control system includes a first working-fluid circuit, a second working-fluid circuit and a first heat exchanger. The first working-fluid circuit includes a first compressor, a second heat exchanger and a first pump. The second heat exchanger is in fluid communication with the first compressor. The first pump receives a first working fluid from the second heat exchanger and circulates the first working fluid through the first working-fluid circuit. The second working-fluid circuit is fluidly isolated from the first working-fluid circuit and includes a second pump and a fourth heat exchanger. The second pump is in fluid communication with the fourth heat exchanger. The first heat exchanger is thermally coupled with the first working-fluid circuit and the second working-fluid circuit.
