うにしたことを特徴とする冷暖房給湯システム。[Scope of Claims] 1. A heating, cooling, and hot water supply system that is installed in a house and performs heating and cooling using a heat medium, which includes a first heat collecting section for absorbing heat from outside air and a first heat collecting section for absorbing heat from underground. a first heat exchanger connected to a second heat collecting section for opening and closing the flow passages through opening/closing means for opening and closing the flow paths, a second heat exchanger installed outdoors; a switching means connected to the first heat exchanger and the second heat exchanger for switching the flow path of the heat medium; a compressor connected to the switching means; and a compressor connected to the switching means indoors. and a hot water storage tank connected to the switching means via a fourth heat exchanger, and the switching means connects the compressor to the first heat exchanger. a first mode for connecting at least one of the third heat exchanger and the fourth heat exchanger via the compressor; and a first mode for connecting the third heat exchanger to the second heat exchanger via the compressor. a second mode for connecting at least one of a heat exchanger and a fourth heat exchanger; and a second mode for connecting at least one of a heat exchanger and a fourth heat exchanger; a third mode in which at least one of a third heat exchanger and a fourth heat exchanger is connected to the connected first and second heat exchangers; and a third mode in which the compressor is connected to the third heat exchanger. through the fourth
An air conditioning, heating, and hot water supply system comprising a fourth mode in which a heat exchanger is connected, and configured to be able to selectively switch between the modes. 2. The air conditioning/heating/hot water system according to claim 1, wherein the first heat collecting section collects heat from attic air of a house. 3. The air-conditioning/heating/hot-water supply system according to claim 1, wherein the second heat exchanger exchanges heat with underfloor air of a house.
