[0044] In some embodiments, the host may further include an outdoor heat exchanger 3, which may be disposed in the second cavity 10b and may include a fan and a fin heat exchanger. The fan may be disposed in a one-to-one correspondence with the air guide port 1321. When the HVAC equipment is heating, the fan is used to extract the external air and the fin heat exchanger for heat exchange, so that the refrigerant inside the fin heat exchanger absorbs the heat of the external air. When cooling, the fan is used to blow the refrigerant heat released by the fin heat exchanger into the outdoor air.

[0045] like Figures 2 to 4 As shown, in some embodiments, the host may further include a shell and tube heat exchanger 4, which may be disposed on the periphery of the water storage device 2 and located between the water storage device 2 and the first panel 131.

The shell and tube heat exchanger 4 may be wound along the axial direction of the water storage device 2, and may be connected to the water storage device 2 to transport hot water generated by heat exchange to the water storage device 2.

[0046] In some embodiments, the shell and tube heat exchanger 4 is at least partially installed in at least one gap 102, and includes at least one heat exchange tube 41. The heat exchange tube 41 may first extend from the bottom end 2a to the top end 2b, then bend and extend along the circumference of the water storage device 2 and then extend from the top end 2b to the bottom end 2a, and may be wound back and forth multiple times, and the specific number of windings may be selected according to actual conditions. In some embodiments, the heat exchange tube 41 may include at least two straight portions 411 and at least one bent portion 412. Each straight portion 411 may extend between the bottom end 2a and the top end 2b, and the bent portion 412 may be formed at the top end of the water storage device 2 and connected to the straight portion 411. Specifically, in some embodiments, there may be two straight portions 411, and there may also be two bent portions 412. Both bent portions 12 are arranged at the top end 2b, and each straight portion 411 corresponds to a gap 102. One of the straight portions 411 extends from the bottom end 2a to the top end 2b and is connected to the bent portion 412. The bent portion 412 is connected to another bent portion 412 by providing a connecting portion 413. Another bent portion 412 can be connected to another straight portion 411. Another straight portion 411 can extend from the top end 2b to the bottom end 2a. The connecting portion 413 is arranged higher than the top end 2a of the water storage device 2, and is located between two adjacent bent portions 412 and connected to the two adjacent bent portions 412.

[0047] In some other embodiments, the straight portion 411 is not limited to two, but may be four, and the four straight portions 411 may be formed on the front and rear sides of the water storage device 2, wherein two straight portions 411 may be located between the water storage device 2 and the first panel 131, and the other two straight portions 411 may be disposed between the water storage device 2 and the back plate 15. In some embodiments, the straight portion 411 may be at least partially disposed in at least one gap 102. Specifically, there may be four straight portions 411, which may be disposed one by one in each gap 102 of the first cavity 10a, thereby making full use of the space of the four gaps 102, thereby avoiding an additional increase in the volume of the host.

[0048] In some other embodiments, the shell and tube heat exchanger 4 is not limited to the above shape, and the shell and tube heat exchanger 4 as a whole can be spiral-shaped and can be wound around the outer circumference of the water storage device 2.

[0049] In some embodiments, the host may further include a water pump 5, which is disposed in the installation space 101 and connected between the shell and tube heat exchanger 4 and the water storage device 2. Specifically, the water pump 5 may be connected to the water inlet of the shell and tube heat exchanger 4 and to the water return port of the water storage device 2, and may be used to transport the water in the water storage device 2 to the shell and tube heat exchanger 4 for heat exchange. In some other embodiments, the water pump 5 may also be connected to the water outlet of the shell and tube heat exchanger 4 and to the hot water inlet and outlet of the water storage device 2, and may be used to pump the hot water in the shell and tube heat exchanger 4 to the water storage device 2. By arranging the water pump 5 in the installation space 101, the bottom space of the water storage device 2 is effectively utilized.

[0050] In some embodiments, the host may further include a compressor (not shown), which may be installed in the installation space 101 and separated from the second cavity 10b by the water receiving tray 17, and may be located on the same side as the second cavity 10b. The compressor (not shown) may be connected to the shell and tube heat exchanger 4. When the HVAC equipment operates in a partial heat recovery or full heat recovery mode, the refrigerant from the compressor (not shown) may exchange heat with water in the shell and tube heat exchanger 4 to prepare hot water. The prepared hot water may enter the water storage device 2. When the user needs hot water, the hot water in the water storage device 2 may be delivered to the corresponding equipment.

[0051] In some embodiments, the host may further include a liquid storage tank 6, which may be installed in the installation space 101 and separated from the second cavity 10b by a water receiving tray 17, and the liquid storage tank 6 and the second cavity 10b may be located on the same side.

[0052] In some embodiments, the host may further include a plate heat exchanger 7, which may be a fluorine-water plate heat exchanger. The plate heat exchanger 7 may be installed in the installation space 101, and the plate heat exchanger 7 and the second cavity 10b may be located on the same side. In some embodiments, the host may further include a plate heat exchanger water pump, and / or an expansion tank. Of course, it is understandable that in some other embodiments, the plate heat exchanger 7, the plate heat exchanger water pump, and / or the expansion tank may also be external.

[0053] In some embodiments, the host further includes an electric control box 8, which is disposed in the first cavity 10a and can be located on the same side as the second cavity 10b. The electric control box 8 is provided with a main control board, relays, reactance and other electrical components. The electric control box 8 is fixed to the inner side of the side plate 14 and is fixed to the two columns of the side plate 14. The electric control box 8 is separated from the second cavity 10b by a water receiving tray 17. Such a configuration increases the stability of the electric control box.
