Abstract
A heat pump includes an indoor heat exchanger; an outdoor heat exchanger that is connected to the indoor heat exchanger; an accumulator that is connected to the outdoor heat exchanger; an evaporative heat exchanger that is provided between the outdoor heat exchanger and the accumulator; and a bypass circuit that that is configured to enable a refrigerant that has flowed out of the indoor heat exchanger to flow into the evaporative heat exchanger.
Claims9
A heat pump configured to circulate a refrigerant for cooling and heating that includes an indoor heat exchanger, an outdoor heat exchanger connected to the indoor heat exchanger, and an accumulator connected to the outdoor heat exchanger, the heat pump comprising:
- a first heat exchanger provided between the outdoor heat exchanger and the accumulator;
- and
- a bypass circuit configured to cause the refrigerant that flows out of the indoor heat exchanger to flow into the first heat exchanger thereby bypassing the outdoor heat exchanger;
- wherein the bypass circuit includes a valve configured to have a degree of opening that is controlled in an opening direction thereof when an outside air temperature is within a range of a predetermined temperature, wherein the degree of opening comprises partially opening the valve in the opening direction.
A heat pump configured to circulate a refrigerant for cooling and heating, the heat pump comprising:
- an indoor heat exchanger;
- an outdoor heat exchanger connected to the indoor heat exchanger;
- an accumulator connected to the outdoor heat exchanger;
- a first heat exchanger provided between the outdoor heat exchanger and the accumulator;
- a second heat exchanger provided between the outdoor heat exchanger and the indoor heat exchanger;
- and
- a bypass circuit configured to cause the refrigerant that flows out of the indoor heat exchanger to flow into the first heat exchanger,
- wherein the bypass circuit includes a valve that is configured to control a flow rate of the refrigerant flowing into the bypass circuit, and
- wherein the valve is located above the first and second heat exchangers in a vertical direction.
