Abstract
A heat pump system for supplying a heated process fluid to a heated process and a chilled process fluid to a chilled process, including a compressor to compress a refrigerant, a hot heat exchanger to receive the heated process fluid, a cold heat exchanger to receive the chilled process fluid and an expansion device (22), wherein the compressor, hot heat exchanger, cold heat exchanger, and expansion device circulate the refrigerant in a serial loop such that the hot heat exchanger can impart heat energy into the heated process fluid and concurrently the cold heat exchanger can absorb heat energy from the chilled process fluid.
Claims20
A heat pump system (10) for supplying a heated process fluid (26,36) to a heated process (2) and for supplying a chilled process fluid (28,38) to a chilled process (4), comprising:
- a compressor (16) to compress a refrigerant (24,34,44,50,54,62,70,84,98,114, 132);
- a hot heat exchanger (18) to receive the heated process fluid (26,36);
- a cold heat exchanger (20) to receive the chilled process fluid (28,38);
- an expansion device (22);
- and
- a heat exchanger (48b) able to receive a circulating fluid and a portion (44j) of said refrigerant (44) exiting said cold heat exchanger (20) and exchange energy therebetween before said refrigerant (44) enters said compressor (16);
- wherein said compressor (16), said hot heat exchanger (18), said cold heat exchanger (20), and said expansion device (22) circulate said refrigerant (24,34,44,50,54,62,70,84,98,114,132) in a first serial loop such that said hot heat exchanger (18) can impart heat energy into the heated process fluid (26,36) and concurrently said cold heat exchanger (20) can absorb heat energy from the chilled process fluid (28,38).
A heat pump system (10) for supplying a heated process fluid (26,36) to a heated process (2) and for supplying a chilled process fluid (28,38) to a chilled process (4), comprising:
- a compressor (16) to compress a refrigerant (24,34,44,50,54,62,70,84,98,114, 132);
- a hot heat exchanger (18) to receive the heated process fluid (26,36);
- a cold heat exchanger (20) to receive the chilled process fluid (28,38);
- an expansion device (22);
- a sub-cooling heat exchanger (52) to receive a first portion (50b) of said refrigerant (50) exiting said hot heat exchanger (18) before it enters said expansion device (20), to receive a second portion (50e) of said refrigerant (50) exiting said cold heat exchanger (20) before it enters said compressor (16), and to exchange energy between said first portion (50b) and said second portion (50e);
- and
- a heat exchanger (60) able to receive a circulating fluid (46) and a third portion (54h) of said refrigerant (54) exiting said sub-cooling heat exchanger (52) and exchange energy therebetween before said refrigerant (54) enters said compressor (16);
- wherein said compressor (16), said hot heat exchanger (18), said cold heat exchanger (20), and said expansion device (22) circulate said refrigerant (24,34,44,50,54,62,70,84,98,114,132) in a first serial loop such that said hot heat exchanger (18) can impart heat energy into the heated process fluid (26,36) and concurrently said cold heat exchanger (20) can absorb heat energy from the chilled process fluid (28,38).
