Abstract
A heat pump system is provided. The heat pump system includes a first compressor and a second compressor and a first heat exchanger, a second heat exchanger, and a third heat exchanger. The system further includes a first expansion device, a second expansion device, and a third expansion device. When the system operates in a cascade heating mode, the third heat exchanger is configured to: receive a first portion of refrigerant from the first compressor and a second portion of refrigerant from the second compressor, and provide a first consistent flow of refrigerant to the first compressor and a second consistent flow of refrigerant to the second compressor so as to improve an efficiency of the system.
