They will not be elaborated here, and all should fall within the protection scope of this application.

[0025] This valve island assembly possesses all the advantages of the integrated oil circuit valve island provided in any of the above embodiments, and will not be repeated here.

[0026] In some examples, such as Figure 4 , Figure 5 and Figure 7 As shown, the valve island assembly also includes a liquid storage tank 400, the connection port of which is connected to the fourteenth interface 134 of the main body 100.

[0027] This valve island assembly integrates the liquid storage tank 400, the electronic expansion valve for refrigeration, the economizer 300, the electronic expansion valve for heating, and the electronic expansion valve for gas replenishment in the heat pump equipment. It also integrates the function of the copper pipe between the liquid storage tank 400, the electronic expansion valve for refrigeration, the economizer 300, the electronic expansion valve for heating, and the electronic expansion valve for gas replenishment through the integrated oil circuit valve island. It has a simple structure and occupies little space.

[0028] In some examples, such as Figure 4 and Figure 5As shown, the economizer 300 is located on the first side of the body 100. The fourth interface 124, fifth interface 125, eleventh interface 131, and twelfth interface 132 are also located on the first side of the body 100. The first port of the first flow channel 310, the second port of the first flow channel 310, the first port of the second flow channel 320, and the second port of the second flow channel 320 are all located on the side of the economizer 300 facing the body 100, facilitating quick assembly of the economizer 300 with the body 100. The second interface 122... The third interface 123, the sixth interface 126, the seventh interface 127, the eighth interface 128, the ninth interface 129, the tenth interface 130, and the thirteenth interface 133 are located on the second side of the main body 100, so as to facilitate connection with the first throttling component 210, the second throttling component 220, the third throttling component 230, the end of the refrigerant flow channel 920 away from the C port of the four-way valve 910, the end of the second heat exchanger 930 away from the E port of the four-way valve 910, and the enthalpy injection port of the compressor (such as through copper pipe).

[0029] In some examples, such as Figure 5 and Figure 6 As shown, the valve island assembly also includes: a mounting bracket 500, an economizer 300 mounted on the mounting bracket 500, and a body 100 mounted on the economizer 300 and spaced apart from the mounting bracket 500; and a vibration damping component 600, which is located between the mounting bracket 500 and the economizer 300, and separates them. The economizer 300 vibrates during refrigerant flow, and the vibration damping component 600 absorbs this vibration energy, thus reducing the vibration of the economizer 300. Furthermore, the vibration damping component 600 separates the mounting bracket 500 and the economizer 300, and the body 100 is spaced apart from the mounting bracket 500, effectively preventing vibrations from the economizer 300 and the body 100 from being transmitted to the mounting bracket 500.

[0030] In some embodiments, such as Figures 4 to 6 As shown, the mounting bracket 500 is a mounting cover. The economizer 300 and the vibration damper 600 are located inside the mounting cover. The main body 100 is located outside the mounting cover and is spaced apart from the mounting cover. The mounting cover is provided with a clearance hole 510 for avoiding the connection structure between the main body 100 and the economizer 300. The connection structure passes through the clearance hole 510 and is spaced apart from the hole wall of the clearance hole 510, so as to prevent the vibration generated by the economizer 300 and the main body 100 from being transmitted to the mounting cover through the hole wall of the clearance hole 510 via the connection structure between the economizer 300 and the main body 100.

[0031] The heat pump equipment provided in the embodiments of this application, such as Figure 2 and Figure 3 As shown, it includes the valve island assembly described in any of the above embodiments.

[0032] This heat pump device possesses all the advantages of the valve island assembly provided in any of the above embodiments, which will not be elaborated further here.

[0033] In some examples, such as Figure 2 and Figure 3 As shown, the heat pump equipment also includes: a housing 700; a partition 800, which is erected inside the housing 700 and separates the interior of the housing 700 into a heat exchange chamber and an installation chamber; a valve island assembly located in the installation chamber; an installation cover fixed to the partition 800, with the opening of the installation cover facing the partition 800; an economizer 300 spaced apart from the partition 800; a main body 100 located on the side of the installation cover facing away from the partition 800; a three-way pipe 140 of the main body 100 located at the upper end of the main body 100; and a liquid storage tank 400 located above the installation cover, facilitating the connection of the liquid storage tank 400 to the fourteenth interface 134 of the three-way pipe 140. The lower end is fixedly connected to the main body 100, and the upper end of the liquid storage tank 400 is fixedly connected to the middle partition 800 and isolated by vibration damping pads. In this scheme, the lower end of the liquid storage tank 400 and the mounting cover together position the economizer 300 and the main body 100, preventing the economizer 300 and the main body 100 from contacting the mounting cover and preventing vibrations on the economizer 300 and the main body 100 from being transmitted to the mounting cover. The vibration damping pads prevent the vibrations of the liquid storage tank 400 from being transmitted to the middle partition 800. Therefore, this scheme can effectively prevent the vibrations of the liquid storage tank 400, the economizer 300 and the main body 100 from being transmitted to the middle partition 800. A second heat exchanger 930 is also present, located within the heat exchange chamber. Reference numeral 940 indicates a gas-liquid separator, reference numeral 950 indicates a compressor, reference numeral 960 indicates a first heat exchanger, and reference numeral 970 indicates a water flow channel.

[0034] The integrated oil circuit valve island of this heat pump equipment simplifies the copper pipe structure in the installation chamber, thus requiring less space for the various components in the installation chamber. Therefore, the volume of the installation chamber can be made smaller, enabling the overall machine to be miniaturized (i.e., the heat pump equipment of this application can be designed to be smaller for the same capacity). Moreover, the simplified copper pipe structure in the installation chamber also results in higher production efficiency.

[0035] In summary, the technical solution provided in this application embodiment fixes the valve island assembly to the partition plate, thereby strengthening and fixing the valve island assembly and preventing leakage at its welding position due to vibration of the valve island assembly.
