Abstract
In an embodiment a system includes a compressor, an indoor heat exchanger, an outdoor heat exchanger, a switch vale, an integrated heat exchanger a first expander and a second expander connected to the refrigerant line, wherein the switch valve is configured to selectively circulate a refrigerant from the compressor either first to the indoor heat exchanger or first to the outdoor heat exchanger, wherein the integrated heat exchanger is configured to receive the refrigerant from the indoor heat exchanger or the outdoor heat exchanger, wherein the integrated heat exchanger is configured to act as a heat pump exchanging heat between the refrigerant and a heat exchange medium, wherein the first expander is configured to selectively expand the refrigerant related to the indoor heat exchanger, wherein the second expander is configured to selectively expand the refrigerant related to the integrated heat exchanger, and a controller configured to control refrigerant circulation directions through the switching valve according to a cooling mode, a heating mode, or a dehumidification mode such that the indoor heat exchanger is able to generate air-conditioning air based on each mode.
