[0052] In related technologies, in order to improve the heat exchange efficiency of the air conditioner outdoor unit in low or high temperature environments, a water-cooled heat exchanger is used to perform water-cooled heat exchange on the refrigerant based on the use of an outdoor heat exchanger for air cooling.

[0053] However, the outdoor unit of the air conditioner includes not only the outdoor heat exchanger and the water-cooled heat exchanger, but also a variety of equipment such as a compressor and a liquid storage tank. So many devices are distributed in the outdoor unit of the air conditioner, resulting in a large volume of the outdoor unit of the air conditioner and a large space occupied.

[0054] In order to solve the above technical problems, the embodiment of the present application provides an air-conditioning outdoor unit and an air conditioner. The air-conditioning outdoor unit and the air conditioner provided by the embodiment of the present application are described in detail below with reference to the accompanying drawings.

[0055] See also Figures 1 to 3 An embodiment of the present application provides an air conditioner, including an air conditioner outdoor unit 100 and an air conditioner indoor unit 200, wherein the air conditioner indoor unit 200 is connected to the air conditioner outdoor unit 100.

[0056] See also Figure 1 and Figure 2 The air conditioner outdoor unit 100 includes a base 110, an outdoor heat exchanger 105, a compressor 101, a shell and tube heat exchanger 103 and a liquid storage tank 102. The base 110 is provided with a middle partition 111; the outdoor heat exchanger 105 is arranged on one side of the middle partition 111; the compressor 101, the shell and tube heat exchanger 103 and the liquid storage tank 102 are arranged on the other side of the middle partition 111, the shell and tube heat exchanger 103 is fixedly arranged on the base 110, the liquid storage tank 102 is passed through the shell and tube heat exchanger 103, and the compressor 101 is fixedly arranged on the upper side of the liquid storage tank 102 and the shell and tube heat exchanger 103 through a bracket assembly.

[0057] See also Figure 3 The inlet of the double-tube heat exchanger 103 is connected to a four-way valve 107, and the outlet of the double-tube heat exchanger 103 is connected to the inlet of the outdoor heat exchanger 105. The outlet of the outdoor heat exchanger 105 is connected to the liquid-side shut-off valve 1010 of the air conditioner outdoor unit 100. The air conditioner outdoor unit 100 also includes a water pump 104, which supplies water to the double-tube heat exchanger 103. The four-way valve 107 is used to switch the air conditioner's operating mode. In cooling mode, the double-tube heat exchanger 103 and the outdoor heat exchanger 105 of the air conditioner outdoor unit 100 release heat to the external environment. The outdoor heat exchanger 105 dissipates heat to the external environment via a fan. The water pump 104 supplies water at a temperature lower than the external ambient temperature to the double-tube heat exchanger 103, so that the high-temperature, high-pressure gaseous refrigerant exchanges heat with the double-tube heat exchanger 103 and condenses into a high-temperature, high-pressure liquid refrigerant. In the heating mode, the shell and tube heat exchanger 103 and the outdoor heat exchanger 105 of the air-conditioning outdoor unit 100 absorb heat from the external environment, and the water pump 104 provides water with a temperature higher than the external environment temperature to the shell and tube heat exchanger 103, so that the low-temperature and low-pressure liquid refrigerant evaporates into a low-temperature and low-pressure gaseous refrigerant after heat exchange with the shell and tube heat exchanger 103.

[0058] The inlet and outlet ends of the liquid storage tank 102 are respectively connected to the four-way valve 107 and the compressor 101. In cooling mode or heating mode, the liquid storage tank 102 can separate the refrigerant returning to the compressor 101 into gaseous refrigerant and liquid refrigerant, preventing the liquid refrigerant from entering the compressor 101 and causing liquid refrigerant accumulation, which could damage the compressor 101.

[0059] In the embodiment of the present application, a shell-and-tube heat exchanger 103 is used as a water-cooled heat exchanger, and the compressor 101 is arranged on the upper side of the shell-and-tube heat exchanger 103 and the liquid storage tank 102, forming an overall layout with upper and lower layers. Moreover, the hollow structure of the shell-and-tube heat exchanger 103 is utilized to fit the liquid storage tank 102 inside the shell-and-tube heat exchanger 103. Therefore, the upper space of the air conditioner outdoor unit 100 and the internal space of the shell-and-tube heat exchanger 103 can be fully utilized, effectively reducing the space occupied, thereby reducing the volume and space occupied by the air conditioner outdoor unit. It can be seen that this solution can solve the problem of large volume and large space occupied by the air conditioner outdoor unit.

[0060] Since the outdoor air conditioner 100 uses both the outdoor heat exchanger 105 and the water-cooled heat exchanger, i.e., the shell-and-tube heat exchanger 103, to dissipate heat from the refrigerant, it has a high heat exchange efficiency. Therefore, the air conditioner with the outdoor air conditioner 100 can be used as a central air conditioner, that is, equipped with multiple indoor air conditioners 200. In other words, the number of indoor air conditioners 200 in the air conditioner can be multiple, and multiple indoor air conditioners 200 can be arranged in parallel. Different indoor air conditioners 200 can be installed in different rooms. Figure 3 Each air conditioner indoor unit 200 can include an indoor electronic expansion valve 201 and an indoor heat exchanger 202 connected in series. One end of the indoor heat exchanger 202 is connected to the gas-side shutoff valve 1011 of the air conditioner outdoor unit 100, and the other end is connected to the liquid-side shutoff valve 1010 of the air conditioner outdoor unit 100 through the indoor electronic expansion valve 201. In this way, when the air conditioner is heating or cooling, heat can be released or absorbed into the indoor environment through the indoor heat exchanger 202.

[0061] In some embodiments, see Figure 2 The bracket assembly may include a vertical plate 121, a first horizontal plate 122, a second horizontal plate 123 and a support seat 124; the vertical plate 121 is inserted into the shell and tube heat exchanger 103, one end of the vertical plate 121 is fixedly connected to the base 110, the other end of the vertical plate 121 extends out of the shell and tube heat exchanger 103, and the liquid storage tank 102 is fixedly connected to the side of the vertical plate 121; the first horizontal plate 122 is fixedly arranged at the other end of the vertical plate 121, the second horizontal plate 123 is fixedly connected to the middle partition 111 and is located at the same horizontal plane as the first horizontal plate 122; the support seat 124 is fixedly arranged on the upper side of the first horizontal plate 122 and the second horizontal plate 123, and the compressor 101 is fixedly connected to the support seat 124.

[0062] The vertical plate 121 extends through the inner tube heat exchanger 103 and is fixedly connected to the base 110. It serves as a fixed foundation for the inner tube heat exchanger 103 and the liquid storage tank 102. The inner tube heat exchanger 103 and the liquid storage tank 102 can be connected to the vertical plate 121 by welding or bolting. The vertical plate 121 can be made of steel plate. A first horizontal plate 122 can be installed on the top of the vertical plate 121 by bending or welding. The first horizontal plate 122 on the top of the vertical plate 121 and the second horizontal plate 123 on the middle partition 111 support the support base 124. The compressor 101 can be fixed to the support base 124, achieving an overall layout of the compressor 101, the inner tube heat exchanger 103, and the liquid storage tank 102 in an upper and lower layer. The compressor 101 can be fixed to the support base 124 by bolts. To reduce vibration, multiple elastic gaskets or elastic cushions, such as plastic washers, can be installed on the bolts.

[0063] See also Figure 2 In some embodiments, the middle partition 111 includes a first partition 112 and a second partition 113, which are arranged at an angle. There are two second transverse plates 123, which are fixedly mounted on the sides of the first partition 112 and the second partition 113, respectively. The angle between the first partition 112 and the second partition 113 can be acute, right, or obtuse.

[0064] The embodiment of the present application sets a first partition 112 and a second partition 113, and two second transverse plates 123 can be set accordingly. By increasing the number of second transverse plates 123, the supporting area of the support seat 124 can be increased, thereby effectively enhancing the supporting strength of the support seat 124, and further improving the stability of the compressor 101 set on the upper side of the shell and tube heat exchanger 103 and the liquid storage tank 102.

[0065] See also Figure 2 In some embodiments, a bending portion 1231 is provided at each end of the second horizontal plate 123, and a first notch is provided on the side of the bending portion 1231 close to the middle partition 111; the bracket assembly also includes a support plate 125, and the side of the support plate 125 is fixedly connected to the middle partition 111, and a second notch is provided on the end of the support plate 125 close to the second horizontal plate 123 to match the first notch, and the second notch abuts the first notch.

[0066] Each second transverse plate 123 can be provided with a support plate 125 at each end, extending downward along the height of the air conditioner outdoor unit 100. The first notched corner of the second transverse plate 123 and the second notched corner of the support plate 125 can both be formed by shearing or other material removal methods. The first notched corner matches the second notched corner, and the size of the notched corners can be flexibly adjusted.

[0067] In the embodiment of the present application, the second notch of the support plate 125 on the middle partition 111 abuts against the first notch of the end of the second transverse plate 123, thereby increasing the contact area between the support plate 125 and the end of the second transverse plate 123 and providing stable support for the second transverse plate 123.

[0068] See also Figure 2 In some embodiments, the first partition 112 is located between the outdoor heat exchanger 105 and the shell and tube heat exchanger 103, and the second partition 113 extends in a direction away from the outdoor heat exchanger 105; a recessed portion 1121 is formed on the first partition 112 corresponding to the shell and tube heat exchanger 103, and the second transverse plate 123 and the support plate 125 on the first partition 112 are arranged in the recessed portion 1121. The outer contour area of the recessed portion 1121 can be equal to or slightly larger than the projected area of the side of the shell and tube heat exchanger 103 on the first partition 112. By providing the recessed portion 1121, the embodiment of the present application can increase the rigidity of the first partition 112 and leave more space for the other side of the middle partition 111, which is convenient for the installation of the shell and tube heat exchanger 103 and the compressor 101.

[0069] See also Figure 2 In some embodiments, the bracket assembly further includes an extension plate 126, which is disposed on an end of the second transverse plate 123 on the second partition plate 113 away from the outdoor heat exchanger 105, and extends toward the base 110; the air conditioner outdoor unit 100 further includes an economizer 106, which is fixedly connected to the extension plate 126. The economizer 106 can be a plate heat exchanger. Figure 1 and Figure 3 Economizer 106 is installed in the pipeline between outdoor heat exchanger 105 and liquid-side shutoff valve 1010 of air conditioner outdoor unit 100. A bypass is also provided between compressor 101 and liquid-side shutoff valve 1010 of air conditioner outdoor unit 100, passing through economizer 106 and connecting to compressor 101. A first outdoor electronic expansion valve 108 is installed in the pipeline between economizer 106 and outdoor heat exchanger 105, and a second outdoor electronic expansion valve 109 is installed in the bypass between economizer 106 and liquid-side shutoff valve 1010. Economizer 106 can divide high-pressure liquid refrigerant into two parts. One part is throttled by the first outdoor electronic expansion valve 108 and further cooled by thermal expansion before entering indoor heat exchanger 202 for refrigeration. The other uncooled gaseous refrigerant passes through the bypass and again through economizer 106 to enter compressor 101 for further compression, absorbing the heat of expansion in economizer 106 and becoming medium-pressure gaseous refrigerant. In this way, the compression work of the compressor 101 can be reduced, thereby improving the capacity and efficiency of the air conditioner.

[0070] In the embodiment of the present application, by providing the extension plate 126, the economizer 106 can be conveniently fixedly arranged next to the compressor 101, which not only facilitates the layout of the pipeline between the economizer 106 and the compressor 101, but also effectively reduces the length of the pipeline between the economizer 106 and the compressor 101, saving materials and costs.

[0071] See also Figure 1 and Figure 2 In some embodiments, the air conditioner outdoor unit 100 further includes a mounting plate 127, one end of which is fixedly connected to the base 110. The mounting plate 127 has a first mounting hole and a second mounting hole defined along the height of the air conditioner outdoor unit 100. The double-tube heat exchanger 103 includes an inlet pipe 1031 and an outlet pipe 1032, with the ends of the outlet pipe 1032 and the inlet pipe 1031 respectively extending through the first mounting hole and the second mounting hole. This ensures that the ends of the outlet pipe 1032 and the inlet pipe 1031 of the double-tube heat exchanger 103 are stably fixed, preventing them from swinging due to external forces. The diameters of the first and second mounting holes on the mounting plate 127 correspond to the outer diameters of the outlet pipe 1032 and the inlet pipe 1031, respectively. Furthermore, the inner walls of the mounting holes may be provided with a cushioning and shock-absorbing material, such as sponge, to reduce the likelihood of vibration of the outlet pipe 1032 and the inlet pipe 1031.

[0072] The water pump 104 is positioned adjacent to the double-tube heat exchanger 103, and can be installed on the water inlet pipe 1031 of the double-tube heat exchanger 103, above the water inlet end of the water inlet pipe 1031. This makes the internal structure of the air conditioner outdoor unit 100 more compact, and the mounting plate 127 not only supports the water inlet pipe 1031, but also supports the water pump 104. To facilitate maintenance and repair of the water pump 104, the housing of the air conditioner outdoor unit 100 can also be provided with an inspection window that can be opened and closed by sliding, pulling, or flipping.
