Abstract
A heat pump system may be operable to circulate fluid between first and second heat exchangers in a first direction in a heating mode and in a second direction in a cooling mode. The heat pump system may include a suction conduit, a low-side compressor and a high-side compressor. The low-side and high-side compressors may both be in fluid communication with the suction conduit.
Claims13
A heat pump system operable in a first heating mode and in a first cooling mode, the heat pump system comprising:
- a high-side compressor including a first suction inlet and a first discharge outlet;
- a low-side compressor including a second suction inlet and a second discharge outlet;
- a discharge conduit having a first end fluidly coupled with said first discharge outlet and a second end fluidly coupled with said second discharge outlet such that said discharge conduit receives compressed working fluid from said low-side compressor in said first heating mode and receives compressed working fluid from said high-side compressor in said first cooling mode;
- a suction conduit in fluid communication with said first and second suction inlets in said first heating mode and in said first cooling mode;
- and
- a high-side bypass conduit having a first control valve and a low-side bypass conduit having a second control valve, wherein working fluid flows through said low-side bypass conduit in said first heating mode and is restricted from flowing through said low-side bypass conduit in said first cooling mode, and wherein working fluid flows through said high-side bypass conduit in said first cooling mode and is restricted from flowing through said high-side bypass conduit in said first heating mode.
