The first heat exchanger 12 is disposed in the housing 11, and air from the gas inlet flows out from the gas outlet after heat exchange by the first heat exchanger 12. Temperature regulation and humidity regulation can be performed using the first heat exchanger 12. The air conditioning unit 1 may also perform a purification treatment or the like on the flowing air. The air conditioning unit water supply pipe interface 14 is used for receiving cold water or hot water in the external water storage device, and the air conditioning unit water return pipe interface 15 is used for discharging the cold water or hot water after the air conditioning unit 1 is used into the water storage device. The cold water or the hot water in the water storage device can be subjected to temperature control through the heat pump unit. The fan coil water supply pipe connection 16 and the fan coil return pipe connection 17 are used for being connected with an inlet and an outlet of the fan coil device respectively. In order to drive the incoming fresh and/or return air through the first heat exchanger 12 and thus out of the gas outlet, a fan may be provided in the housing 11. An air conditioning unit water supply pipe interface 14, an air conditioning unit return pipe interface 15, a fan coil water supply pipe interface 16, and a fan coil return pipe interface 17 may be provided on the housing 11.
