ABSTRACT:
A heat pump system includes a first heat exchanger, a second heat exchanger in fluid communication with the first heat exchanger, a scroll compressor in fluid communication with each of the first and second heat exchangers, and a flash tank in fluid communication with each of the first and second heat exchangers and the scroll compressor. The flash tank includes an inlet fluidly coupled to the first and second heat exchangers and receives liquid refrigerant from the first and second heat exchangers. The flash tank also includes a first outlet fluidly coupled to the first and second heat exchangers that delivers sub-cooled-liquid refrigerant to the second heat exchanger and a second outlet fluidly coupled to the scroll compressor that delivers vaporized refrigerant to the scroll compressor in a heating mode.
