摘要： 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.

摘要： A heat pump includes a first and second heat exchanger, a scroll compressor and a flash tank in fluid communication. The flash tank includes an inlet fluidly coupled to the heat exchangers to receive liquid refrigerant. Furthermore, the flash tank includes a first outlet fluidly coupled to the first and second heat exchangers and a second outlet fluidly coupled to the scroll compressor. The first outlet is operable to deliver sub-cooled-liquid refrigerant to the heat exchangers while the second outlet is operable to deliver vaporized refrigerant to the scroll compressor. An expansion valve is further provided and is operable to selectively open and close the inlet by a float device. The float device is operable to control an amount of liquid refrigerant disposed within the flash tank by regulating an amount of liquid refrigerant entering the flash tank via the inlet.

摘要： A system including an evaporator, a variable capacity compressor coupled in fluid communication with the evaporator, a condenser coupled in fluid communication between the compressor and the evaporator, an expansion valve disposed intermediate the condenser and the evaporator, and an isolation valve disposed intermediate the condenser and the expansion valve is provided. The isolation valve is in communication with the compressor to respectively synchronize opening and closing thereof with on- and off-cycles of the compressor to prohibit migration of liquid refrigerant. In an alternative embodiment, first and second check valves are respectively associated with the compressor and the condensor for prohibiting reverse migration of refrigerant during off-cycle.
