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. A first capillary tube is disposed between the first heat exchanger and an inlet of the flash tank and a first valve is disposed between the first heat exchanger and the first capillary tube to control refrigerant to the first capillary tube.
Claims16
A heat pump system comprising:
- a scroll compressor in a fluid circuit with a flash tank, a first heat exchanger and a second heat exchanger;
- a first capillary tube disposed between first heat exchanger and an inlet of said flash tank;
- a second capillary tube disposed between said first heat exchanger and said inlet of said flash tank;
- and
- a first valve disposed between said first heat exchanger and said first capillary tube and operable between an open state and a closed state, said valve allowing refrigerant to flow through said first capillary tube in said open state and preventing said refrigerant from flowing through said first capillary tube in said closed state.
In a heat pump system circulating refrigerant between a first heat exchanger and a second heat exchanger in a fluid circuit including a scroll compressor, a vapor injection system comprising:
- a flash tank in fluid communication with each of the first and second heat exchangers and the scroll compressor;
- a first capillary tube disposed between the first heat exchanger and an inlet of said flash tank;
- a second capillary tube disposed between the first heat exchanger and said inlet of said flash tank;
- and
- a first valve disposed between the first heat exchanger and said first capillary tube and operable between an open state and a closed state, said valve allowing refrigerant to flow through said first capillary tube in said open state and preventing said refrigerant from flowing through said first capillary tube in said closed state.
