Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration, and in particular to a heat dissipation system for a heat pump air conditioner controller and a working method thereof. Background Art

[0002] As an energy-efficient air conditioning device, the heat pump variable-frequency air conditioner has been widely used in modern buildings. However, as the "brain" of the system, the heat pump variable-frequency air conditioner controller will generate a large amount of heat when continuously working in a high-temperature environment. If the heat cannot be dissipated in time and effectively, the temperature of the core components of the controller will rise sharply, affecting its operation speed and accuracy, and even causing system failures, resulting in the abnormal operation of the air conditioner. Usually, the variable-frequency air conditioner will reduce the compressor frequency in a high-temperature environment to avoid the temperature rise of the core components of the controller, but this will greatly reduce the refrigeration effect and seriously affect the comfort of users.

[0003] During the refrigeration process of traditional air conditioners, condensate will be generated on the surface of the evaporator. These condensates are usually collected and discharged. However, the condensate has a certain amount of cold energy before being discharged. If this part of the cold energy can be effectively utilized to dissipate heat from the controller, it will help improve the energy efficiency of the air conditioner. The publication number is CN108731246A, which provides a radiator, a controller and an air conditioner, relating to the technical field of air conditioners, and solving the technical problems of the unchangeable direction of the radiator, poor heat dissipation effect and inability to meet the design requirements. The radiator is connected to the component to be cooled through a commutation structure, and there is a wind source for heat exchange with the radiator beside the radiator; the wind source is a fan, and when there is an included angle between the direction of the cold air provided by the wind source and the direction of the air flow passage in the radiator, the included angle is reduced to zero through the commutation structure. This air conditioner uses air-cooled heat dissipation and requires an additional heat dissipation wind source, and the air-cooled heat dissipation effect is not good in an external high-temperature environment. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a heat dissipation system for a heat pump air conditioner controller with good heat dissipation effect and a working method thereof, to ensure that the variable-frequency air conditioner can operate normally under high-temperature conditions and provide sufficient refrigeration capacity for users.

[0005] To achieve the above purpose, the solution provided by the present invention is: a heat dissipation system for a heat pump air conditioner controller, including an indoor unit, a water storage tank, a water pump, a radiator, and a controller. The controller is arranged on the radiator, and the radiator is used to absorb the heat generated by the controller. The indoor unit includes an evaporator, and the water storage tank is arranged directly below the evaporator. The water storage tank is used to collect the condensate generated by the evaporator. The water storage tank is respectively connected with a water outlet pipe and a diversion pipe. The water outlet pipe is connected to the water pump, the water pump is connected with a water inlet pipe, the water inlet pipe is connected to the radiator, and the radiator is connected to the diversion pipe.

[0006] The beneficial effects of the present invention are: effective heat dissipation of the controller is achieved. The heat dissipation system is provided with a water tank, a water pump, a radiator, and a controller. The water tank collects condensed water generated by the indoor unit, and then the condensed water is transported to the radiator through the water pump. The radiator uses the condensed water to dissipate heat from the controller, and the condensed water after absorbing heat can flow back to the water tank for reuse. In this way, accurate heat dissipation of the controller is achieved, ensuring that the heat pump variable frequency air conditioner can obtain better heat dissipation effect under a higher temperature environment. Under the premise that the controller does not generate condensed water and short-circuit, the supply of condensed water to the radiator can be accurately adjusted to avoid high-temperature burning of the controller module, so as to ensure that the heat pump air conditioner can operate normally under high temperature conditions and can still provide users with sufficient cooling comfort effects. It is of great significance to improve the performance reliability of the heat pump variable frequency air conditioner.

[0007] Furthermore, a first return pipe is connected between the water pump and the water tank. After the present invention adopts the above structure, when the water level in the water tank is lower than the set height, the water delivered to the water pump can be returned to the water tank through the first return pipe to avoid insufficient water in the water tank and no load on the water pump.

[0008] Furthermore, a sensor is arranged between the water storage tank and the first return pipe. After the present invention adopts the above structure, the water level in the water storage tank and the water flow in the first return pipe can be detected.

[0009] Furthermore, a second return pipe is connected between the water pump and the radiator. After the present invention adopts the above structure, the amount of condensed water delivered to the radiator can be increased or reduced.

[0010] Furthermore, filters are respectively arranged between the drainage end of the evaporator, the water storage tank and the water outlet pipe. After the present invention adopts the above structure, impurities in the condensed water when entering the water storage tank and the water pump can be effectively filtered.

[0011] Furthermore, the water storage tank is connected to a drain pipe. After the present invention adopts the above structure, when the water in the water storage tank is too high, the excess condensed water can be discharged.

[0012] Furthermore, the radiator is provided with a plurality of flow channels, the water inlet pipes are respectively connected to the plurality of flow channels, and the plurality of flow channels are respectively connected to the flow guide pipes. The present invention improves the heat dissipation effect by adopting the above structure.

[0013] Furthermore, a temperature sensor is provided on the controller. The present invention can detect the temperature of the controller by adopting the above structure.

[0014] The present invention also includes a working method of the heat dissipation system, comprising the following steps: S1. Execute Order 1; S2. When 0 < Tm - 95 ≤ 15, execute Command Two until stable operation, then execute Command Three. If Tm1 is less than the dew point temperature of the air Td + 5, immediately execute Command Four and then continue to execute Command One; if Tm1 is greater than or equal to the dew point temperature of the air Td + 5, execute Command Five; S3. When 15 < Tm - 95 ≤ 30, it is necessary to execute Command Six and execute Command Three during operation. If Tm1 is less than the dew point temperature of the air Td + 5, execute Command Two; if Tm1 is greater than or equal to the dew point temperature of the air Td + 5, execute Command Five; S4. When 30 < Tm - 95, execute Command Seven and execute Command Three during operation. If Tm1 is less than the dew point temperature of the air Td + 5, execute Command Six; if Tm1 is greater than or equal to the dew point temperature of the air Td + 5, execute Command Five; S5. When Tm - 95 < 0, execute Command Eight and then continue to execute Command One.

[0015] Among them, Command One: After stable operation for 30 minutes, monitor the temperature Tm of the controller; Command Two: Adjust the water pump to the low speed gear; Command Three: Monitor whether the temperature Tm1 of the controller is less than the dew point temperature of the air Td + 5; Command Four: Turn off the water pump; Command Five: Continue to operate and monitor the temperature Tm2 of the controller; Command Six: Adjust the water pump to the medium speed gear; Command Three: Monitor whether the temperature Tm1 of the controller is less than the dew point temperature of the air Td + 5; Command Seven: Adjust the water pump speed to the high speed gear; Command Eight: Do not start the liquid cooling system and keep the water pump off. Through the above working method, the present invention can automatically adjust the gear of the water pump according to factors such as the temperature of the controller and the operating state of the air conditioner, so as to accurately adjust the supply amount of condensed water to the radiator on the premise of ensuring that the controller does not generate condensed water and short - circuit, effectively reduce the temperature of the controller, and achieve the best heat dissipation effect and energy efficiency ratio.

[0016] Further, in step S2, when Tm1 > Tm2 and Tm1 - Tm2 < 15, continue to execute Command Three; when 15 ≤ Tm1 - Tm2, execute Command Four and then continue to execute Command One; when 0 < Tm2 - 95 ≤ 15, execute Command Six; when 15 < Tm2 - 95, execute Command Seven.

Detailed Embodiments

[0023] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] See attached Figure 1 to attached Figure 3As shown in the figure, a heat dissipation air-conditioning control system using condensed water includes an indoor unit 1, a water storage tank 2, a water pump 3, a radiator 4, and a controller 5. The controller 5 is disposed on the radiator 4, and the radiator 4 is used to absorb the heat generated by the controller 5. The indoor unit 1 includes an evaporator. The water storage tank 2 is disposed directly below the evaporator, and the water storage tank 2 is used to collect the condensed water generated by the evaporator. The water storage tank 2 is respectively connected with a water outlet pipe 21 and a diversion pipe 22. The water outlet pipe 21 is connected to the water pump 3, the water pump 3 is connected with a water inlet pipe 31, the water inlet pipe 31 is connected to the radiator 4, and the radiator 4 is connected to the diversion pipe 22.

[0026] In this embodiment, a first return pipe 23 is connected between the water pump 3 and the water storage tank 2, an inductor 24 is disposed between the water storage tank 2 and the first return pipe 23, and the water storage tank 2 is connected with a drain pipe 25. In this embodiment, a plurality of flow channels 41 are formed on the radiator 4. The water inlet pipe 31 is respectively connected to a plurality of flow channels 41, and the plurality of flow channels 41 are respectively connected to the diversion pipe 22.

[0027] In this embodiment, a second return pipe 32 is connected between the water pump 3 and the radiator 4. Specifically, the second return pipe 32 is connected to a plurality of flow channels 41.

[0028] In this embodiment, filters 26 are respectively disposed between the drainage end of the evaporator, the water storage tank 2 and the water outlet pipe 21.

[0029] In this embodiment, a temperature sensor is disposed on the controller 5. The temperature sensor is installed on the controller 5. When the detected temperature of the controller 5 reaches a preset value, the water pump 3 is started to pump the condensed water into the radiator 4. In addition, the controller 5 can also control the gear of the water pump 3 according to factors such as the temperature of its modules and the operating state of the air conditioner to dynamically adjust the utilization amount of the condensed water, so as to achieve the best heat dissipation effect and energy efficiency ratio.

[0030] When the external environmental temperature is relatively high, after the indoor unit 1 of this embodiment enters the refrigeration mode, the temperatures of the modules of the controller 5 increase. Only relying on air cooling may not be able to meet the heat dissipation requirements. Therefore, it is necessary to combine water cooling for heat dissipation at the same time. The gear of the water pump 3 is reasonably adjusted mainly by monitoring the temperature of the controller 5. Although the temperature requirement of each component module is lower than 125 °C, the average temperature of each component is relatively high and cannot be used as the requirement for long-term operation. Therefore, it is necessary to keep the temperature of each component module not higher than 95 °C.

[0031] The water storage tank 2, the water pump 3, the radiator 4, the water outlet pipe 21, the diversion pipe 22, the first return pipe 23, the drain pipe 25, the water inlet pipe 31, the second return pipe 32, and the controller 5 form a complete liquid cooling loop. The water storage tank 2 collects the condensed water filtered by the filter 26 from the indoor unit 1.

[0032] To prevent excessive condensate in the water storage tank 2 from causing excessive load on the water storage tank 2, a drain pipe 25 is provided on one side of the water storage tank 2. When the water level in the water storage tank 2 reaches a certain height, the drain pipe 25 automatically discharges the excess condensate. A filter 26 is provided at the bottom of the water storage tank 2 to filter the condensate entering the water pump 3 again and prevent impurities from entering the cooling circuit.

[0033] The radiator 4 is closely attached to the heat-generating part of the controller 5 to absorb heat. The water pump 3 drives the condensate in the water storage tank 2 to circulate and flow, taking away the heat from the radiator 4.

[0034] At the same time, a sensor 24 is provided on the water storage tank 2 to monitor the water level of the water storage tank 2. Only when the water level reaches a certain height, the first return pipe 23 is closed and the water pump 3 is controlled to start; when the water level in the water storage tank 2 is lower than the set height, the water pump 3 is closed, and the water output from the water outlet pipe 21 to the water pump 3 flows back to the water storage tank 2 through the first return pipe 23 to prevent insufficient water volume in the water storage tank 2 and the water pump from being idling.

[0035] By monitoring the temperature of relevant modules on the controller 5, the gear of the water pump 3 is controlled through the second return pipe 32 to dynamically adjust the utilization amount of the condensate. The second return pipe 32 can output or suck back the condensate according to the water pump 3 to increase or decrease the flow rate of the condensate entering the flow channel 41. At a high gear, the flow rate of the condensate entering the flow channel 41 is increased, and so on for medium and low gears. The higher the gear, the greater the flow rate of the condensate entering the flow channel 41.

[0036] In this regard, this embodiment further includes a working method for the heat dissipation system of the heat pump air conditioner controller, including the following steps: S1. In the cooling mode, the water pump 3 is started. The water pump 3 sucks the condensate in the water storage tank 2. The condensate enters the water pump 3 through the water outlet pipe 21, and then enters multiple flow channels 41 of the radiator 4 through the water inlet pipe 31 respectively. The condensate absorbs the heat generated by the controller 5 in the multiple flow channels 41 respectively, and then flows back to the water storage tank 2 through the diversion pipe 22. Finally, command one is executed. After stable operation for 30 minutes, the temperature Tm of the controller 5 is monitored.

[0037] S2. When 0 < Tm - 95 ≤ 15, execute Command 2, and adjust the water pump 3 to the low speed gear. To avoid short - circuit faults caused by condensation water on the module due to the temperature of the controller 5 after water cooling being lower than the dew point temperature of the air, therefore, after stable operation, execute Command 3 to monitor whether the temperature Tm1 of the controller 5 is less than the dew point temperature of the air Td + 5. If Tm1 is less than the dew point temperature of the air Td + 5, immediately execute Command 4 to turn off the water pump 3, and then continue to execute Command 1. After stable operation for 30 minutes, monitor the temperature Tm of the controller 5. If Tm1 is greater than or equal to the dew point temperature of the air Td + 5, during operation, the temperature of the controller 5 will change with the environment and the operation of the system, then execute Command 5 to continue running and monitor the temperature Tm2 of the controller 5.

[0038] When Tm1 > Tm2 and Tm1 - Tm2 < 15, it indicates that during the low - speed operation of the water pump, the ambient temperature has decreased or other factors have caused a small decrease in the temperature of the controller 5, but the water pump 3 still needs to run at low speed for cooling. Continue to execute Command 3 to monitor whether the temperature Tm1 of the controller 5 is less than the dew point temperature of the air Td + 5. When 15 ≤ Tm1 - Tm2, it indicates that during the low - speed operation of the water pump, the ambient temperature has decreased significantly or other factors have caused a large decrease in the temperature of the controller 5, and liquid cooling is not required. Execute Command 4 to turn off the water pump 3, and then continue to execute Command 1. After stable operation for 30 minutes, monitor the temperature Tm of the controller 5. When 0 < Tm2 - 95 ≤ 15, it indicates that during the low - speed operation of the water pump, the ambient temperature has increased or other factors have caused an increase in the temperature of the controller 5, and the low - speed gear of the water pump 3 cannot meet the heat dissipation requirements. Execute Command 6 to adjust the water pump 3 to the medium - speed gear. When 15 < Tm2 - 95, it indicates that during the low - speed operation of the water pump 3, the ambient temperature has increased significantly or other factors have caused a large increase in the temperature of the controller 5. Execute Command 7 to adjust the speed of the water pump 3 to the high - speed gear.

[0039] S3. When 15 < Tm - 95 ≤ 30, it indicates that the module temperature is relatively high. Execute Command 6 to adjust the water pump 3 to the medium - speed gear. During operation, execute Command 3 to monitor whether the temperature Tm1 of the controller 5 is less than the dew point temperature of the air Td + 5. If Tm1 is less than the dew point temperature of the air Td + 5, the high gear of the water pump 3 causes a large decrease in the temperature of the controller 5, which is likely to cause condensation and short - circuit of the controller 5, and Command 2 needs to be executed. If Tm1 is greater than or equal to the dew point temperature of the air Td + 5, then execute Command 5 to continue running and monitor the temperature Tm2 of the controller 5.

[0040] If Tm1 > Tm2 and Tm1 - Tm2 < 15, during the operation of the water pump 3 in the medium speed gear, the ambient temperature decreases or other factors cause a slight decrease in the temperature of the controller 5. However, the water pump 3 still needs to operate at medium speed for cooling. Execute Command Three to monitor whether the temperature Tm1 of the controller 5 is less than the air dew point temperature Td + 5. If 15 ≤ Tm1 - Tm2 < 30, it indicates that during the operation of the water pump 3 in the medium speed gear, the ambient temperature decreases or other factors cause a relatively large decrease in the temperature of the controller 5. The water pump 3 does not need to be adjusted to the medium speed gear, so execute Command Two to adjust the water pump 3 to the low speed gear. If 30 ≤ Tm1 - Tm2, during the operation of the water pump 3 in the medium speed gear, the ambient temperature decreases significantly or other factors cause a relatively large decrease in the temperature of the controller 5, and liquid cooling is not required. Execute Command Four to turn off the water pump 3, and then continue to execute Command One. After stable operation for 30 minutes, monitor the temperature Tm of the controller 5. If 0 < Tm2 - 95, it indicates that during the operation of the water pump 3 in the medium speed gear, the ambient temperature rises significantly or other factors cause a significant increase in the temperature of the controller 5, so execute Command Seven to adjust the speed of the water pump 3 to the high speed gear.

[0041] S4. When 30 < Tm - 95, it indicates that the module temperature is too high. Then execute Command Seven to adjust the speed of the water pump 3 to the high speed gear. During the operation, execute Command Three to monitor whether the temperature Tm1 of the controller 5 is less than the air dew point temperature Td + 5. If Tm1 is less than the air dew point temperature Td + 5, the high gear of the water pump 3 causes a relatively large decrease in the temperature of the controller 5, which is likely to cause condensation and short circuit of the controller 5. Execute Command Six to adjust the water pump 3 to the medium speed gear. If Tm1 is greater than or equal to the air dew point temperature Td + 5, execute Command Five to continue the operation and monitor the temperature Tm2 of the controller 5.

[0042] If Tm1 > Tm2 and Tm1 - Tm2 < 15, during the medium-speed operation of the water pump 3, the ambient temperature decreases or other factors cause a slight decrease in the temperature of the controller 5. However, the water pump 3 still needs to operate at high speed for cooling. Execute Command 3 to monitor whether the temperature Tm1 of the controller 5 is less than the air dew point temperature Td + 5. If 15 ≤ Tm1 - Tm2 < 30, it indicates that during the high-speed operation of the water pump 3, the ambient temperature decreases or other factors cause a large decrease in the temperature of the controller 5. The water pump 3 does not need to be adjusted to the high-speed gear, so execute Command 6 to adjust the water pump 3 to the medium-speed gear. If 30 ≤ Tm1 - Tm2 < 45, during the high-speed operation of the water pump 3, the ambient temperature decreases significantly or other factors cause a large decrease in the temperature of the controller 5. The water pump 3 does not need to be adjusted to the high-speed gear. Execute Command 2 to adjust the water pump 3 to the low-speed gear. If 45 ≤ Tm1 - Tm2, during the high-speed operation of the water pump 3, the ambient temperature decreases significantly or other factors cause a large decrease in the temperature of the controller 5. Liquid cooling is not required. Execute Command 4 to turn off the water pump 3, and then continue to execute Command 1. After stable operation for 30 min, monitor the temperature Tm of the controller 5.

[0043] S5. When Tm - 95 < 0, it indicates that the module temperature is relatively low. Execute Command 8 to not start the liquid cooling system and keep the water pump 3 closed. However, the environment or other factors may change and cause the temperature of the controller 5 to rise. Therefore, it is necessary to continue to execute Command 1. After stable operation for 30 min, monitor the temperature Tm of the controller 5.

[0044] Among them, Command 1: After stable operation for 30 min, monitor the temperature Tm of the controller 5. Command 2: Adjust the water pump 3 to the low-speed gear. Command 3: Monitor whether the temperature Tm1 of the controller 5 is less than the air dew point temperature Td + 5. Command 4: Turn off the water pump 3. Command 5: Continue to operate and monitor the temperature Tm2 of the controller 5. Command 6: Adjust the water pump 3 to the medium-speed gear. Command 7: Adjust the speed of the water pump 3 to the high-speed gear. Command 8: Do not start the liquid cooling system and keep the water pump 3 closed.

[0045] In this embodiment, by monitoring the temperature of the controller 5, on the premise of ensuring that the controller 5 does not short-circuit due to condensed water, the gear of the water pump 3 can be automatically adjusted to accurately control the supply amount of condensed water to the radiator 4.

[0046] In this embodiment, the condensed water used has a relatively high thermal conductivity coefficient, which can quickly absorb and transfer the heat generated by the controller 5, improving the heat dissipation efficiency.

[0047] The condensed water can be evenly distributed in the flow channels 41 of the radiator 4, reducing local overheating of the radiator 4 and thus reducing local overheating of the components in the controller 5, improving the working stability of the controller 5. Through heat dissipation by the condensed water, the working temperature of the controller 5 drops significantly, extending its service life.

[0048] Utilizing the condensed water for heat dissipation can reduce the dependence on traditional cooling systems, and precisely controlling the gear of the water pump 3 effectively reduces energy consumption.

[0049] As a natural cooling medium, the condensed water reduces the dependence on chemical coolants and decreases environmental pollution.

[0050] The heat dissipation system of this embodiment has a simple structure. It only optimizes the structure of the traditional air-cooled radiator, facilitating integration into a compact controller design. Moreover, the system of this embodiment is relatively easy to maintain, reducing the long-term operation cost.

[0051] The heat dissipation system of this embodiment has a relatively low cost, which helps to reduce the overall manufacturing cost. The heat dissipation system of this embodiment is energy-saving and easy to maintain, further reducing the long-term operation cost.

[0052] The above-described embodiments are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make more possible changes and modifications to the technical solution of the present invention by using the disclosed technical content above, or modify it into equivalent embodiments with equivalent changes. Therefore, all equivalent changes made according to the idea of the present invention without departing from the content of the technical solution of the present invention shall be covered by the protection scope of the present invention.
