[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] Please see Figure 1The present invention provides an air conditioning unit 10, which can be a computer room air conditioner, such as a high-density back panel air conditioner. The air conditioning unit 10 can cool, heat, and humidify to meet the usage needs of the cabinet in different environments, thus helping to ensure that the cabinet is maintained in a suitable temperature environment.

[0024] The air conditioning unit 10 includes a housing 11, a refrigeration module 12, a humidification module 13, a heating module 14, and a liquid control module 15. The refrigeration module 12, the humidification module 13, the heating module 14, and the liquid control module 15 are all installed inside the housing 11. The housing 11 can provide a certain degree of protection for the components inside the housing 11, which helps to prevent the components inside the housing 11 from being exposed and damaged.

[0025] The refrigeration module 12 can meet the refrigeration needs of the air conditioning unit 10, the humidification module 13 can meet the humidification needs of the air conditioning unit 10, and the heating module 14 can meet the heating needs of the air conditioning unit 10. Thus, the refrigeration module 12 and the humidification module 13 can work together to meet the refrigeration and humidity needs of the air conditioning unit 10. The refrigeration module 12 can also work together with the humidification module 13 and the heating module 14 to meet the constant temperature and humidity needs of the air conditioning unit 10. This helps to meet the usage needs of the air conditioning unit 10 in different environments.

[0026] The refrigeration module 12 includes a piping assembly 121 and a heat exchanger 122. The piping assembly 121 is connected to the heat exchanger 122. The heat exchanger 122 can meet the heat exchange of high-temperature air in the air conditioning unit 10. The refrigerant can circulate through the piping assembly 121 to the heat exchanger 122 to maintain the normal operation of the heat exchanger 122.

[0027] For example, the refrigeration module can be connected to a unit such as a condenser outside the housing 11. The refrigerant can enter the heat exchanger 122 from the piping assembly 121, and after being cooled and depressurized in the heat exchanger 122, it flows to the unit through the piping assembly 121. After being heated and depressurized in the unit, it re-enters the heat exchanger 122 through the piping assembly 121, thereby maintaining the refrigeration cycle of the air conditioning unit 10.

[0028] In some embodiments, the heat exchanger 122 includes an air inlet side 1221 and an air outlet side 1222 facing away from each other. The high-temperature air in the air conditioning unit 10 can flow from the air inlet side 1221 to the heat exchanger 122, and after exchanging heat with the heat exchanger 122, it is converted into low-temperature air and flows out through the air outlet side 1222, which helps to maintain the cooling operation of the air conditioning unit 10 and ensure the heat dissipation effect of the air conditioning unit 10 on the cabinet.

[0029] The humidification module 13 is located on the air inlet side 1221. When the humidity of the air inside the air conditioning unit 10 is insufficient, the humidification module 13 can work to increase the humidity of the air. In this way, the humidity of the air flowing through the heat exchanger 122 is increased, which helps to ensure that the air after heat exchange through the heat exchanger 122 has a certain humidity. This helps to meet the usage requirements of the air conditioning unit 10 to adapt to the low humidity environment of the cabinet.

[0030] For example, the humidification module 13 may include a humidifier 131, a humidification switch valve 132, and a humidification pipeline 133. The humidification switch valve 132 is located on the humidification pipeline 133, and the humidifier 131 may be a wet film humidifier 131, which helps to improve the humidification efficiency of the air conditioning unit 10. The air conditioning unit 10 may also include an electrical control 19, which is electrically connected to the humidification switch valve 132. When the humidity of the air inside the air conditioning unit 10 is insufficient, the electrical control 19 can control the opening of the humidification switch valve 132. At this time, the humidification pipeline 133 is open, and liquid can enter the humidifier 131 through the humidification pipeline 133. The humidifier 131 works to humidify the air, so the low humidity air inside the air conditioning unit 10 can have its humidity increased under the action of the humidifier 131, and then enter the heat exchanger 122 through the air inlet side 1221 for heat exchange.

[0031] When the humidity of the air inside the air conditioning unit 10 is sufficient, the electrical control 19 can control the humidification switch valve 132 to close. At this time, the humidification pipeline 133 is cut off, the humidifier 131 stops working, and the air inside the air conditioning unit 10 can directly enter the heat exchanger 122 through the humidifier 131 for heat exchange.

[0032] It should be noted that the air conditioning unit 10 also dehumidifies during the cooling process. Therefore, when the humidification module 13 is working, the humidification rate of the humidification module 13 should be greater than the dehumidification rate of the air conditioning unit 10. This helps to ensure that the air conditioning unit 10 can adapt to the low humidity environment of the cabinet.

[0033] The heating module 14 is located on the air outlet side 1222. When the air temperature inside the air conditioning unit 10 is too low, the heating module 14 can work to raise the air temperature. In this way, the air after heat exchange through the heat exchanger 122 can flow to the heating module 14 through the air outlet side 1222. The air after heat exchange can be appropriately heated in the heating module 14 before being delivered to the cabinet. This helps to ensure that the air output by the air conditioning unit 10 has a suitable temperature, thus helping to meet the requirements of the air conditioning unit 10 to adapt to the constant temperature of the cabinet.

[0034] For example, the heating module 14 may include a heater 141, and the electrical control 19 is electrically connected to the heater 141. When the temperature of the air inside the air conditioning unit 10 is too low, the electrical control 19 can control the heater 141 to turn on and work. The heater 141 heats the air, so the low-temperature air inside the air conditioning unit 10 can be heated by the heater 141 and delivered to the cabinet. When the temperature of the air inside the air conditioning unit 10 is appropriate, the electrical control 19 can control the heater 141 to stop working. At this time, the air in the air conditioning unit 10 after heat exchange can directly enter the cabinet through the heater 141.

[0035] In some embodiments, the liquid control module 15 is connected to the refrigeration module 12 and is located on the air inlet side 1221. The liquid control module 15 can control the flow rate of refrigerant entering the refrigeration module 12, which helps to ensure the normal operation of the air conditioning unit 10 in low-temperature environments.

[0036] The liquid control module 15 includes a first switching valve 151, a liquid storage tank 152, and a second switching valve 153. Both the first switching valve 151 and the second switching valve 153 are located in the pipeline assembly 121. The first switching valve 151 can selectively open or close the pipeline assembly 121 connected to the liquid inlet end of the liquid storage tank 152. The second switching valve 153 can selectively open or close the pipeline assembly 121 connected between the liquid outlet end of the liquid storage tank 152 and the heat exchanger 122. The flow rate of refrigerant in the pipeline assembly 121 can be controlled by opening and closing the first switching valve 151 and the second switching valve 153.

[0037] For example, the electrical control 19 is electrically connected to the first switching valve 151 and the second switching valve 153. When the air conditioning unit 10 is in a low-temperature environment, such as when the air conditioning unit 10 is at -10 degrees, -20 degrees, -30 degrees, -35 degrees or other low temperatures, the electrical control 19 can control the opening of the first switching valve 151 and the second switching valve 153. At this time, the pipeline assembly 121 is open, and the refrigerant can enter the heat exchanger 122 through the pipeline assembly 121.

[0038] When the air conditioning unit 10 is in a high-temperature environment, such as in a hot summer environment, the air temperature inside the air conditioning unit 10 is high. In order to ensure that the heat exchanger 122 has sufficient heat exchange effect, the amount of refrigerant required for heat exchange needs to be appropriately increased. When the air conditioning unit 10 is in a cold winter environment, the air temperature inside the air conditioning unit 10 is low. Therefore, the amount of refrigerant required for heat exchanger 122 is relatively less than that in the summer environment. At this time, the liquid receiver 152 can store the excess refrigerant in the heat exchanger 122, which helps to prevent excessive refrigerant from accumulating in the heat exchanger 122 and causing the heat exchanger 122 to malfunction.

[0039] In some embodiments, the housing 11 may be provided with a heat exchange chamber 111 and an air supply chamber 112. The cooling module 12, the humidifying module 13 and the liquid control module 15 are all located in the heat exchange chamber 111. The air conditioning unit 10 includes an air supply module 16, which is used to guide the air in the heat exchange chamber 111 to the air supply chamber 112, thereby helping to improve the air flow efficiency in the air conditioning unit 10.

[0040] For example, the air supply module 16 may include a fan 161 and an air guide ring 162, with the air guide ring 162 connected to the fan 161. The air guide ring 162 helps improve the air supply efficiency of the fan 161. In this way, the air inside the air conditioning unit 10 can be cooled by the cooling action of the refrigeration module 12 and delivered to the air supply cavity 112 by the action of the air supply module 16, which helps to ensure the normal operation of the air conditioning unit 10.

[0041] The heating module 14 is connected to the air supply module 16. The heating module 14 can be connected to the side of the air guide ring 162 away from the fan 161, that is, the heater 141 can be connected to the side of the air guide ring 162 away from the fan 161. In this way, when the air conditioning unit 10 needs to output constant temperature air, the electrical control 19 can control the heater 141 to work. The air entering the air supply cavity 112 needs to be heated by the heater 141 before entering the air supply cavity 112, which helps to ensure the uniformity of the air temperature in the air supply cavity 112.

[0042] Air in the heat exchange chamber 111 can enter the air supply chamber 112 under the action of the air supply module 16. At this time, the heater 141 can heat up the air entering the heater 141. When the temperature is raised to an appropriate temperature, the air supply module 16 introduces the heated air into the air supply chamber 112.

[0043] In this way, the cooling module 12 can work together with the heating module 14 to meet the cooling and constant temperature requirements of the air conditioning unit 10, which helps the air conditioning unit 10 adapt to the use requirements of the cabinet in a constant temperature environment.

[0044] The heating module 14 can be installed in the heat exchange chamber 111 or in the air supply chamber 112, as long as the heating module 14 is connected to the air supply module 16.

[0045] Please refer to the following: Figure 2 and Figure 3In some embodiments, the housing 11 may include an air inlet cover 113 and an air outlet cover 114. The air inlet cover 113 has an air inlet portion 1131 that connects to the heat exchange chamber 111, and the air outlet cover 114 has an air outlet portion 1141 that connects to the air supply chamber 112. Thus, air from outside the air conditioning unit 10 can enter the heat exchange chamber 111 through the air inlet portion 1131 for heat exchange, and the heat-exchanged air can enter the air supply chamber 112 and be discharged from the air conditioning unit 10 through the air outlet portion 1141, thereby helping to maintain the normal operation of the air conditioning unit 10.

[0046] The housing 11 may also include a first air outlet side cover 115, a second air outlet side cover 116, and a mounting cover 117. The first air outlet side cover 115 and the second air outlet side cover 116 are connected to opposite sides of the air outlet top cover 114, and the mounting cover 117 is connected to the first air outlet side cover 115, the second air outlet side cover 116, and the air outlet top cover 114. This helps to ensure the compactness of the housing 11 structure.

[0047] For example, the first air outlet side cover 115 can be the front cover of the housing 11, the second air outlet side cover 116 can be the rear cover of the housing 11, and the mounting cover 117 can be the right cover of the housing 11. The first air outlet side cover 115 and the second air outlet side cover 116 are respectively connected to the front and rear sides of the air outlet top cover 114, and the mounting cover 117 is connected to the right side of the air outlet top cover 114 and connects to the first air outlet side cover 115 and the second air outlet side cover 116. Thus, when a component in the air supply cavity 112 malfunctions, the user can access the air supply cavity 112 by removing the mounting cover 117 to repair or replace the faulty component, facilitating user operation.

[0048] Both the first air outlet side cover 115 and the second air outlet side cover 116 are provided with air supply sections 118. The air in the air supply cavity 112 can be discharged from the air conditioning unit 10 through the air supply sections 118 of the first air outlet side cover 115 and the second air outlet side cover 116. The air in the air supply cavity 112 can also be discharged from the air conditioning unit 10 through the air outlet section 1141, which helps to improve the air supply efficiency of the air conditioning unit 10.

[0049] The distance between the air outlet 1141 and the mounting cover 117 along the length of the housing 11 is equal to the distance between the air supply part 118 and the mounting cover 117 along the length of the housing 11. For example, the distance between the air supply part 118 of the first air outlet side cover 115 and the mounting cover 117 along the length of the housing 11 is the first distance; the distance between the air supply part 118 of the second air outlet side cover 116 and the mounting cover 117 along the length of the housing 11 is the second distance; and the distance between the air outlet part 1141 of the air outlet top cover 114 and the mounting cover 117 along the length of the housing 11 is the third distance. The first distance, the second distance, and the third distance are all equal. At this time, the air supply part 118 of the first air outlet side cover 115 and the air outlet part 1141 are aligned, and the air supply part 118 of the second air outlet side cover 116 and the air outlet part 1141 are aligned. Then, the air in the air supply cavity 112 can be discharged from the air supply part 118 of the first air outlet side cover 115, the air supply part 118 of the second air outlet side cover 116, and the air outlet part 1141 at the same time, which helps to ensure the uniformity of the air outlet temperature of the air conditioning unit 10.

[0050] Please refer to the previous document. Figure 1 In some embodiments, the piping assembly 121 may include a first heat exchange tube 1211, a second heat exchange tube 1212, and a third heat exchange tube 1213. A liquid control module 15 is connected to the first heat exchange tube 1211 and the second heat exchange tube 1212. The first heat exchange tube 1211 is connected to the inlet end of the liquid storage tank 152, the second heat exchange tube 1212 is connected to the outlet end of the liquid storage tank 152 and the inlet end of the heat exchanger 122, and the third heat exchange tube 1213 is connected to the outlet end of the heat exchanger 122. The refrigerant can then circulate through the first heat exchange tube 1211, the second heat exchange tube 1212, and the third heat exchange tube 1213 within the heat exchanger 122 to maintain its normal operation.

[0051] The first switching valve 151 can be a one-way valve, and the second switching valve 153 can be a solenoid valve. The first switching valve 151 is located on the first heat exchange tube 1211, and the second switching valve 153 is located on the second heat exchange tube 1212. The first switching valve 151 is configured to open the first heat exchange tube 1211 from the liquid inlet end to the liquid outlet end. The one-way valve can restrict the flow of refrigerant, which helps to prevent refrigerant from flowing back from the liquid inlet end to the first heat exchange tube 1211 and affecting the normal operation of the liquid control module 15. The second switching valve 153 can selectively open or close the second heat exchange tube 1212, so the electronic control unit 19 can control the opening or closing of the solenoid valve to maintain the normal operation of the air conditioning unit 10.

[0052] In some embodiments, the refrigeration module 12 may further include a first pressure sensor 123 and a second pressure sensor 124. The first pressure sensor 123 is disposed on the first heat exchange tube 1211, and the first switching valve 151 is disposed relative to the first pressure sensor 123 near the liquid inlet end of the liquid storage tank 152. The second pressure sensor 124 is disposed on the third heat exchange tube 1213.

[0053] The first pressure sensor 123 can detect the pressure of the refrigerant entering the first heat exchange tube 1211, and the second pressure sensor 124 can detect the pressure of the refrigerant entering the second heat exchange tube 1212. The electronic control unit 19 can control the opening of the second switching valve 153 according to the pressure detected by the first pressure sensor 123 and the second pressure sensor 124. For example, when the pressure detected by the first pressure sensor 123 and the second pressure sensor 124 is too high, the electronic control unit 19 can reduce the opening of the second switching valve 153. When the pressure detected by the first pressure sensor 123 and the second pressure sensor 124 is too low, the electronic control unit 19 can increase the opening of the second switching valve 153, which helps to ensure that the pressure in the pipeline assembly 121 is maintained in a suitable pressure environment.

[0054] Furthermore, the electronic control unit 19 can also control the opening of the second switching valve 153 based on the pressure detected by the first pressure sensor 123 and the second pressure sensor 124, and based on the ambient temperature required by the air conditioning unit 10. For example, when the cooling capacity of the heat exchanger 122 is insufficient, the electronic control unit 19 can increase the opening of the second switching valve 153, thereby increasing the flow rate of refrigerant through the heat exchanger 122, which helps to increase the cooling capacity of the heat exchanger 122; when the cooling capacity of the heat exchanger 122 is too large, the electronic control unit 19 can decrease the opening of the second switching valve 153, thereby reducing the flow rate of refrigerant through the heat exchanger 122, which helps to reduce the cooling capacity of the heat exchanger 122.

[0055] Thus, the first pressure sensor 123 and the second pressure sensor 124 help ensure that the refrigeration module 12 is in a suitable pressure environment, and also help improve the working efficiency of the air conditioning unit 10.

[0056] In some embodiments, the air conditioning unit 10 may further include a water receiving component 171 and a drain component 172, with the drain component 172 connected to the water receiving component 171. Both the refrigeration module 12 and the humidification module 13 are located within the water receiving component 171. Since condensate will condense on the surface of the heat exchanger 122 during the cooling, dehumidification, and humidification processes of the air conditioning unit 10, the water receiving component 171 can collect the condensate on the surface of the heat exchanger 122. When the condensate in the water receiving component 171 accumulates to a certain level, the drain component 172 operates and discharges the condensate outside the air conditioning unit 10. For example, a drain pump (not shown in the figure) may be provided on the drain component 172, which can discharge the condensate outside the air conditioning unit 10 through the drain pump. This helps to prevent condensate from accumulating in the heat exchange chamber 111 and affecting the normal operation of the air conditioning unit 10.

[0057] In some embodiments, the water receiving element 171 can be a water receiving tray.

[0058] In some embodiments, the air conditioning unit 10 may also include a water immersion sensor 18, which is installed in the heat exchange chamber 111 and spaced apart from the water inlet 171. The water immersion sensor 18 may be located between the air outlet side 1222 and the heater 141. The water immersion sensor 18 can detect whether there is liquid inside the housing 11. An electrical control 19 is installed in the heat exchange chamber 111 and electrically connected to the water immersion sensor 18. The electrical control 19 can control the air conditioning unit 10 to stop working when the water immersion sensor 18 detects liquid inside the housing 11, which helps to reduce the risk of damage to the components inside the air conditioning unit 10.

[0059] For example, when the drain 172 fails, the condensate in the water inlet 171 cannot be discharged from the air conditioning unit 10. When the condensate in the water inlet 171 accumulates to a certain level, the condensate will overflow into the housing 11. At this time, the water immersion sensor 18 detects that there is liquid in the housing 11 and sends a signal to the electrical control 19. The electrical control 19 can receive the signal sent by the water immersion sensor 18 and control the humidification switch valve 132 and the second switch valve 153 and other devices to close. The heat exchanger 122, humidifier 131, heater 141 and other devices stop working. This helps to prevent the condensate overflowing into the housing 11 from damaging the operating devices and helps to reduce the risk of device damage.

[0060] In summary, the air conditioning unit 10 provided in this embodiment of the invention has its refrigeration module 12, humidification module 13, and heating module 14 all installed within the housing 11. The housing 11 provides a certain degree of protection for these components, helping to prevent damage to exposed parts. The refrigeration module 12 meets the cooling requirements of the air conditioning unit 10, the humidification module 13 meets the humidification requirements, and the heating module 14 meets the heating requirements.
