[0045] In some embodiments, the support structure 3 is disposed on the chassis 11, extending from the chassis 11 to the cavity 10, and supports the water tank module 21 and the outdoor heat exchanger module 22, so as to define a receiving space 30 in the area below the water tank module 21 and the outdoor heat exchanger module 22. Specifically, the receiving space 30 is located in the lower area of ​​the cavity 10.

[0046] In some embodiments, there may be at least two supporting structures 3 . Of course, it can be understood that in some other embodiments, there may be more than two supporting structures 3 .

[0055] In some embodiments, the water pump 24 can be arranged in the first accommodating space 30a, and the compressor 26, the air-conditioning side heat exchanger 25, the reversing valve and / or the expansion water tank can be arranged in the second accommodating space 30b, so as to make full use of the space at the bottom of the water tank module 21, save the connecting pipes between the components, reduce the loss, and help improve the system stability and reduce the operating noise and vibration.

[0056] In some embodiments, the outdoor unit can complete heating, cooling, and preparation of domestic hot water without the need for additional matching equipment such as hydraulic modules and domestic hot water modules, thereby improving product integration, reducing the complexity of installing multiple devices during the engineering installation process, and improving user experience.

[0057] like Figure 6 As shown, the outdoor unit of the present application can operate in cooling + domestic hot water mode, cooling + partial heat recovery mode, heating + domestic hot water mode, pure hot water mode, heating mode alone and cooling mode alone.

[0058] 1. When in cooling + domestic hot water mode, full heat recovery can be used at the beginning. The B port and C port of the first three-way valve 281 are connected, and the B port and C port of the second three-way valve 282 are connected. All the heat of the high-temperature refrigerant is exchanged at the domestic hot water heat exchanger 27, so that when cooling in summer, the condensation heat originally used for heat exchange with the air is all used to prepare hot water, and the condenser does not need to start heat dissipation. It is equivalent to the refrigerant undergoing a phase change at the domestic hot water heat exchanger 27, condensing from gas to liquid, releasing latent heat, and then directly entering the liquid storage tank 23, and then passing through the first expansion valve 201 to the evaporator (air conditioning side heat exchanger 25) for evaporation to achieve the cooling effect, and finally the refrigerant returns to the gas-liquid separator 20 and then returns to the compressor 26 for a new cycle.

[0059] 2. When the domestic hot water reaches a certain temperature, it can be switched to the refrigeration + partial heat recovery mode. The B port and C port of the first three-way valve 281 are connected, and the A port and C port of the second three-way valve 282 are connected. Part of the heat of the high-temperature refrigerant is exchanged at the domestic hot water heat exchanger 27, and the other part of the heat is released through the condenser (outdoor heat exchanger module 22). It is equivalent to the refrigerant releasing sensible heat at the domestic hot water heat exchanger 27, and then passing through the four-way valve 29, the condenser (finned heat exchanger 222), the liquid storage tank 23, and the first expansion valve 201 in sequence to reach the evaporator (air conditioning side heat exchanger 25) for evaporation to achieve the refrigeration effect. Finally, the refrigerant returns to the gas-liquid separator 20 and then returns to the compressor 26 for a new cycle.

[0060] 3. When in heating + domestic hot water mode, the B port and C port of the first three-way valve 281 are connected, and the A port and C port of the second three-way valve 282 are connected. Part of the heat of the high-temperature refrigerant is exchanged at the domestic hot water heat exchanger 27, and the other part of the heat is released through the condenser (air conditioning side heat exchanger 25) to achieve the indoor heating effect. Then the refrigerant passes through the liquid storage tank 23, the second expansion valve 202, and the evaporator (outdoor heat exchanger module 22) in sequence to evaporate and absorb the heat of the outdoor air, and finally returns to the gas-liquid separator 20 and then to the compressor 26 for a new cycle.

[0061] 4. During transitional seasons or other special times, the system can be used as a water heater heat pump to operate in pure hot water mode. The B and C ports of the first three-way valve 281 are connected, and the B and C ports of the second three-way valve 282 are connected. All the heat of the high-temperature refrigerant is exchanged at the domestic hot water heat exchanger 27 to produce hot water, and then passes through the liquid storage tank 23 and the second expansion valve 202 to the evaporator (outdoor heat exchanger module 22) to evaporate and absorb the heat of the outdoor air, and finally returns to the gas-liquid separator 20 and then to the compressor 26 for a new cycle.

[0062] 5. In the single heating mode, the A port and the C port of the first three-way valve 281 are connected, and the B port and the C port of the second three-way valve 282 are connected. After the high-temperature refrigerant comes out of the compressor 26, it passes through the first three-way valve 281 and the four-way valve 29 in sequence and then directly reaches the condenser (air conditioning side heat exchanger 25) for release to achieve the indoor heating effect. Then the refrigerant passes through the liquid storage tank 23, the second expansion valve 202, and the evaporator (fin heat exchanger 222) in sequence to evaporate and absorb the heat of the outdoor air, and finally returns to the gas-liquid separator 20 and then returns to the compressor 26 for a new cycle.

[0063] 6. In the single cooling mode, the A port and the C port of the first three-way valve 281 are connected, and the B port and the C port of the second three-way valve 282 are connected. After the high-temperature refrigerant comes out of the compressor 26, it passes through the first three-way valve 281 and the four-way valve 29 in sequence and then directly reaches the condenser (outdoor heat exchanger module 22) to release heat, and then passes through the liquid storage tank 23 and the first expansion valve 201 in sequence to reach the evaporator (air conditioning side heat exchanger 25) for evaporation to achieve the cooling effect. Finally, the refrigerant returns to the gas-liquid separator 20 and then enters the compressor 26 for a new cycle.

[0064] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model.
