Abstract
An apparatus includes a compressor, a first heat exchanger, a reheater, a first valve, a second heat exchanger, a four-way valve, a cap tube, and a blower. The compressor compresses a refrigerant. The blower moves air proximate the second heat exchanger to the reheater. During a heating mode of operation, the four-way valve is configured to direct refrigerant from the compressor to the second heat exchanger; the second heat exchanger is configured to use the refrigerant from the compressor to heat air proximate the second heat exchanger; and the cap tube is configured to allow refrigerant to bypass the reheater.
Claims20
An apparatus comprising:
- a compressor configured to compress a refrigerant;
- a first heat exchanger;
- a reheater;
- a first valve;
- a second heat exchanger;
- a four-way valve;
- a cap tube;
- and
- a blower configured to move air proximate the second heat exchanger to the reheater;
- wherein during a heating mode of operation:
- the four-way valve is configured to direct refrigerant from the compressor to the second heat exchanger;
- the second heat exchanger is configured to use the refrigerant from the compressor to heat air proximate the second heat exchanger;
- and
- the cap tube is configured to allow refrigerant to bypass the reheater.
A method comprising:
- compressing, by a compressor, a refrigerant;
- and
- during a heating mode of operation:
- adjusting a four-way valve to direct refrigerant from the compressor to the second heat exchanger;
- using, by a second heat exchanger, the refrigerant from the compressor to heat air proximate the second heat exchanger;
- and
- allowing, by a cap tube, refrigerant to bypass a reheater.
