Specifically, as shown in fig. 1, the first refrigerant channel 201 is provided with a stop valve 280, and is connected to an indoor heat exchanger 300 of an indoor unit of an air conditioner via the stop valve 280, so that the refrigerant provided by the outdoor refrigerant module 200 can exchange heat through the indoor heat exchanger 300, and heating or cooling of the indoor environment can be achieved. The air-conditioning indoor unit of the embodiment may be a vertical cabinet unit, a wall-mounted indoor unit, an air duct unit, or the like, and is not particularly limited. Referring to fig. 2, in the embodiment of the present invention, the hydraulic module 100 is integrally installed in the outdoor unit 1000, and both the hydraulic module 100 and the outdoor refrigerant module 200 are installed in a casing (not shown) of the outdoor unit 1000. The second refrigerant flow path 202 is directly connected to the heat exchange pipeline 122, so that the refrigerant provided by the outdoor refrigerant module 200 can exchange heat through the water-side heat exchanger 120.
Referring to fig. 1 and 2, it can be understood that the outdoor refrigerant module 200 can provide refrigerant to the hydraulic module 100 and the indoor heat exchanger 300 for heat exchange, that is, the hydraulic module 100 and the indoor unit of the air conditioner share the same outdoor refrigerant module 200, and only the outdoor unit 1000 of the air conditioner needs to be installed outdoors, and the water inlet interface 131 and the water outlet interface 141 are disposed on the casing, so as to be conveniently connected to the water-consuming equipment. Therefore, the hydraulic module 100 does not need to be arranged outdoors or indoors separately, the installation space and the cost are saved, and the noise problem caused by the fact that the hydraulic module 100 is placed indoors can be avoided; and the heat exchange pipeline 122 of the hydraulic module 100 can be directly connected with the outdoor refrigerant module 200, so that the use of refrigerant connecting pipes is effectively reduced, the installation is simple and convenient, the cost is lower, the problems of leakage and maintenance caused by the installation of the connecting pipes are also avoided, the capacity loss is effectively reduced, the heat exchange efficiency can be improved, and the design is more reasonable and practical.
It should be noted that the air conditioning indoor unit and the hydraulic module 100 may operate simultaneously, and at this time, the outdoor refrigerant module 200 may be capable of simultaneously delivering the refrigerant to the hydraulic module 100 and the indoor heat exchanger 300. To explain by taking heating as an example, referring to fig. 1, a first valve port D of a four-way valve 240 is communicated with a fourth valve port E, a second valve port S is communicated with a third valve port C, a high-temperature refrigerant discharged from an exhaust port of a compressor 210 sequentially passes through the first valve port D and the fourth valve port E, and a part of the refrigerant flows to an indoor heat exchanger 300 through a first refrigerant flow path 201 to exchange heat, thereby heating an indoor environment; another part of the refrigerant flows to the water side heat exchanger 120 through the second refrigerant flow path 202, so that the refrigerant exchanges heat with water, and the water flow path 101 generates hot water and delivers the hot water to the water consumption equipment through the water outlet pipe 140. The heat-exchanged refrigerant sequentially passes through the throttling part 230, the outdoor heat exchanger 220, and the four-way valve 240 and then flows back to the compressor 210.
Referring to fig. 1, it can be understood that, in some embodiments, the outdoor refrigerant module 200 further includes a switch valve (not shown in the drawings), the switch valve is disposed in the second refrigerant flow path 202, the second refrigerant flow path 202 can be opened or closed by the switch valve, when the switch valve is opened, the heat exchange pipeline 122 is conducted, and at this time, the refrigerant can exchange heat through the water-side heat exchanger 120; when the switch valve is closed, the heat exchange pipeline 122 is disconnected, and the refrigerant does not flow through the water-side heat exchanger 120. It can be understood that, considering that the hydraulic module 100 is mainly used for providing hot water to water consuming devices such as an air energy water heater or a floor heating device, when the indoor unit of the air conditioner needs to refrigerate, a low-temperature refrigerant can flow through the first refrigerant flow path 201, and at this time, the water side heat exchanger 120 does not need to exchange heat with the refrigerant to produce cold water, so that the second refrigerant flow path 202 can be closed through the switch valve, and the water pump 110 stops working, that is, the hydraulic module 100 does not work, so that the water temperature of the water consuming devices is not affected when the indoor unit of the air conditioner refrigerates.
Referring to fig. 1, it can be understood that the throttling part 230 of the embodiment includes a first electronic expansion valve 231 and a capillary tube 232, one end of the first electronic expansion valve 231 is connected to the first refrigerant channel 201, the other end is connected to one end of the capillary tube 232, and the other end of the capillary tube 232 is connected to the outdoor heat exchanger 220. During heating, the refrigerant exchanges heat through the first refrigerant flow path 201 and the second refrigerant flow path 202, and then sequentially passes through the first electronic expansion valve 231 and the capillary tube 232 for throttling. The first electronic expansion valve 231 and the capillary tube 232 both have the functions of throttling and depressurizing, that is, the refrigerant is throttled in two stages. It should be noted that, compared with a throttling structure using only one electronic expansion valve or capillary tube, the embodiment performs two-stage throttling on the refrigerant, so that the pressure of the refrigerant can be further reduced, the liquid refrigerant is increased, the refrigerant flow can be increased, and the heat exchange efficiency can be improved.
Referring to fig. 1, it can be understood that in the embodiment, a second electronic expansion valve 250 is further disposed on the second refrigerant flow path 202, and a refrigerant heat dissipation pipe 260 is disposed between the second electronic expansion valve 250 and the first electronic expansion valve 231.

The refrigerant heat dissipation pipe 260 is disposed at an electric control board (not shown in the drawings) of the outdoor unit 1000, and is used for dissipating heat from the electric control board. It can be understood that, during heating, the refrigerant in the second refrigerant flow path 202 passes through the water side heat exchanger 120 and then is throttled by the second electronic expansion valve 250, and the throttled refrigerant which generates low-temperature and low-pressure flows through the refrigerant radiating pipe 260 to exchange heat, so that the refrigerant radiating effect on the electronic control board can be achieved, the refrigerant utilization rate is improved, and the operation stability of the electronic control board is favorably maintained.
