Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the numbers used in this way can be interchanged where appropriate so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0044] Figure 1 This is a schematic diagram of the structure of a temperature compensation system provided by an embodiment of the present invention. Figure 1The temperature compensation system 100 includes a waste heat output module 10, a detection module 20, a reversing module 30, a control module 40, and a heat dissipation module 50. The detection module 20 is used to detect temperature information inside the electrical box. The control module 40 is electrically connected to the detection module 20 and the reversing module 30, respectively, and is used to control the working state of the reversing module 30 according to the temperature information, so as to control the flow path of the output fluid of the waste heat output module 10. The heat dissipation module 50 is connected to the reversing module 30, and is used to heat the interior of the electrical box when the output fluid flows through the heat dissipation module 50.

[0045] Specifically, in some special environmental conditions, air conditioning equipment must operate in extremely low temperatures. In these conditions, the electrical box of the air conditioning equipment, especially the outdoor unit electrical box, can fail due to low temperatures. For example, when the ambient temperature drops below -25°C, the components inside the electrical box will fail due to low temperatures, causing various malfunctions of the air conditioning equipment.

[0046] The temperature compensation system 100 of the present invention can utilize the output fluid generated by the waste heat output module 10 to heat the electrical box 60. The temperature compensation system 100 may include a detection module 20, a reversing module 30, a control module 40, and a heat dissipation module 50. The detection module 20 is used to detect the ambient temperature inside the electrical box 60. The control module 40 is electrically connected to the reversing module 30 and the detection module 20, respectively, and controls the working state of the reversing module 30 based on the temperature information detected by the detection module 20. The detection module 20 may include a temperature sensor, which is disposed inside the electrical box 60 and is used to collect temperature information inside the electrical box 60 in real time. The control module 40 is connected to the detection module 20 and can obtain temperature information inside the electrical box 60 from the detection module 20. The control module 40 includes, but is not limited to, a single-chip microcomputer.

[0047] The heat dissipation module 50 is connected to the reversing module 30, and the control module 40 controls the flow path of the output fluid by controlling the operating state of the reversing module 30. The output fluid generated by the waste heat output module 10 can flow through the reversing module 30 to the heat dissipation module 50, where the heat of the output fluid itself is used to heat the interior of the electrical box. When the detection module 20 detects that temperature information will cause the electrical box to fail due to low temperature, the control module 40 controls the operating state of the reversing module 30 so that the output fluid generated by the waste heat output module 10 is input to the heat dissipation module 50, where heat is dissipated, thereby heating the interior of the electrical box 60 and preventing the components within the electrical box 60 from failing due to low temperature. The electrical box 60 can be an electrical box for an air conditioning unit, which can be a modular unit or a direct expansion unit. For example, when the detection module 20 detects that the temperature inside the electrical box 60 is below a preset threshold, the control module 40 controls the operating state of the reversing module 30, directing the output fluid from the waste heat output module 10 through the reversing module 30 and into the heat dissipation module 50. The heat dissipation module 50 dissipates heat to heat the electrical box 60, thereby preventing components inside the electrical box 60 from failing due to low temperatures. For example, the preset threshold may be -25°C.

[0048] The temperature compensation system provided by the embodiment of the present invention uses a detection module to detect the temperature information inside the electrical box in real time. The control module controls the working state of the reversing module based on the temperature information. When the electrical box needs to be heated, the working state of the reversing module is controlled so that the output fluid generated by the waste heat output module is input into the heat dissipation module through the reversing module, and the heat dissipation module heats the electrical box. The technical solution of the embodiment of the present invention can provide a relatively stable temperature environment for the electrical box, so that it is not affected by the external low temperature environment, prevent the electrical box from failing due to low temperature, and ensure the normal operation of the air conditioner. At the same time, it can also reduce the probability of damage to the electrical components inside the electrical box, enhance the reliability and safety of the air conditioning equipment, and increase the service life of the air conditioning equipment.

[0049] Optional, Figure 2 This is a schematic diagram of the structure of another temperature compensation system provided by an embodiment of the present invention. Figure 2 The waste heat output module 10 includes a compressor 11 and a heat exchange unit 12. The compressor 11 is connected to the heat exchange unit 12 for outputting waste heat gas. The heat exchange unit 12 is connected to the reversing module 30 and is used to convert the waste heat gas into liquid, which serves as the output fluid.

[0050] Specifically, the waste heat output module 10 in the temperature compensation system 100 may include a compressor 11 and a heat exchange unit 12 of the air conditioning equipment. The compressor 11 generates high-temperature waste heat gas during normal cooling and heating processes. The output end of the compressor 11 is connected to the input end of the heat exchange unit 12, and the high-temperature waste heat gas generated by the compressor 11 is transported to the heat exchange unit 12. In the heat exchange unit 12, the high-temperature waste heat gas undergoes heat exchange, and the heat exchange unit 12 converts the high-temperature waste heat gas into a high-temperature liquid. The control module 40 then controls the operating state of the reversing module 30, so that the high-temperature liquid is transported to the heat dissipation module 50 through the reversing module 30. The high-temperature liquid dissipates heat under the action of the heat dissipation module 50, thereby increasing the ambient temperature inside the electrical box and heating the electrical components inside the electrical box 60. This prevents the electronic components inside the electrical box 60 from failing due to low temperatures and affecting the normal operation of the air conditioning equipment.

[0051] The heat dissipation module 50 and the detection module 20 are both located inside the electrical box 60. The detection module 20 is used to detect the temperature inside the electrical box 60 and transmit the temperature information to the control module 40. After receiving the temperature information, the control module 40 controls the operating state of the reversing module 30 based on the temperature information. When the electrical box 60 needs to be heated, the reversing module 30 transfers the high-temperature liquid converted by the heat exchange unit 12 to the heat dissipation module 50 inside the electrical box 60 to heat the electronic components inside the electrical box 60. The internal devices of the electrical box 60 include electronic components, such as relays, contactors, and transformers.

[0052] Optional, Figure 3 This is a schematic diagram of the structure of another temperature compensation system provided by an embodiment of the present invention. Figure 3 The heat exchange unit 12 includes a heat exchanger 121 and a fan 122 ; the heat exchanger 121 is connected to the compressor 11 and is used to convert the waste heat gas output by the compressor 11 into liquid; the fan 122 is connected to the control module 40 and is used to adjust the conversion efficiency of the waste heat gas into liquid under the control of the control module 40 .

[0053] Specifically, the main function of the heat exchange unit 12 is to convert the high-temperature waste heat gas generated by the compressor 11 into a high-temperature liquid. The high-temperature waste heat gas generated by the compressor 11 is transported to the heat exchanger 121, where it undergoes heat exchange. The fan 122 converts the high-temperature waste heat gas into a high-temperature liquid. The fan 122 accelerates air flow, lowers the surface temperature of the heat exchanger 121, and thereby improves the efficiency of heat exchange, thereby accelerating the conversion of the waste heat gas into the high-temperature liquid. Driven by the fan 122, the high-temperature waste heat gas undergoes heat exchange within the heat exchanger 121, converting it into a high-temperature liquid. This high-temperature liquid is then transported to the reversing module 30. For example, the heat exchanger 121 may be a condenser. Under the control of the control module 40, the reversing module 30 transports the high-temperature liquid generated by the heat exchanger 121 to the heat dissipation module 50 for heating the electrical box 60 when heating is required. When heating is not required, the high-temperature liquid generated by the heat exchanger 121 is output to the liquid pipe 70.

[0054] Optionally, based on the above embodiment, continue to refer to Figure 3 The reversing module 30 includes an input terminal a, a first output terminal b, and a second output terminal c. The input terminal a is connected to the heat exchange unit 12, the first output terminal b is connected to the heat dissipation module 50, and the second output terminal c is connected to the liquid pipe 70. The control module 40 is further configured to control the first output terminal b to be conductive when the temperature information is less than a preset threshold, and to control the second output terminal c to be conductive when the temperature information is greater than or equal to the preset threshold.

[0055] Specifically, the control module 40 controls the working state of the reversing module 30 according to the temperature information so as to control the flow path of the high-temperature liquid. The reversing module 30 includes an input terminal a, a first output terminal b, and a second output terminal c. The input terminal a is connected to the output terminal of the heat exchange unit 12, and the high-temperature liquid generated by the heat exchange unit 12 is transported to the reversing module 30 through the input terminal a. After the high-temperature liquid is transported to the reversing module 30, the control module 40 controls the working state of the reversing module 30 according to the temperature information to control the flow path of the high-temperature liquid. When the temperature information detected by the detection module 20 is lower than the preset threshold, it means that the temperature inside the electrical box 60 is low at this time, and the electrical box is at risk of low-temperature failure at any time. Then, the control module 40 controls the first output terminal b of the reversing module 30 to be turned on. The high-temperature liquid is transported to the heat dissipation module 50 through the first output terminal b, and the electronic components inside the electrical box 60 are heated by the heat dissipation module 50. When the temperature detected by the detection module 20 is greater than or equal to a preset threshold, indicating that the temperature inside the electrical box 60 will not affect the electronic components and the normal operation of the air conditioner, the control module 40 controls the second output terminal c of the reversing module 30 to be conductive. The second output terminal c is connected to the liquid pipe 70, through which the high-temperature liquid is supplied to the normal operation of the air conditioner. The preset threshold can be set according to actual needs and is not specifically limited in this invention. For example, the preset threshold may be -25°C. When the detection module 20 detects that the temperature inside the electrical box is -30°C, the control module 40 controls the first output terminal b of the reversing module 30 to be conductive. The high-temperature liquid is transported through the first output terminal b to the heat dissipation module 50, where it heats the electronic components inside the electrical box 60. When the detection module 20 detects that the temperature inside the electrical box is -20°C, the control module 40 controls the second output terminal c of the reversing module 30 to be conductive. The high-temperature liquid is then output to the liquid pipe 70 and continues to circulate in the fluorine system.

[0056] Optional, Figure 4 This is a schematic diagram of the structure of another temperature compensation system provided by an embodiment of the present invention. Figure 4 The temperature compensation system 100 also includes a one-way conducting module 80; a first end of the one-way conducting module 80 is connected to the heat dissipation module 50, a second end of the one-way conducting module 80 is connected to the liquid pipe 70, and a control end of the one-way conducting module 80 is electrically connected to the control module 40. The control module 40 is further configured to control the one-way conducting module 80 to conduct when the temperature information is less than a preset threshold, and to control the one-way conducting module 80 to shut down when the temperature information is greater than or equal to the preset threshold.

[0057] Specifically, the temperature compensation system 100 also includes a unidirectional conduction module 80. A first end of the unidirectional conduction module 80 is connected to the heat dissipation module 50, a second end is connected to the liquid pipe 70, and a control end is connected to the control module 40. When the temperature information is less than a preset threshold, the control module 40 controls the reversing module 30 to transport the high-temperature liquid to the heat dissipation module 50. After the heat dissipation in the heat dissipation module 50, the high-temperature liquid is transported to the liquid pipe 70 through the unidirectional conduction module 80. When the temperature information is greater than or equal to the preset threshold, the control module 40 directly controls the reversing module 30 to output the high-temperature liquid to the liquid pipe 70. At this time, the control module 40 controls the guide conduction module 50 to shut down, preventing the high-temperature liquid from flowing into the heat dissipation module 50 through the unidirectional conduction module 80. When the high-temperature liquid is directly output from the reversing module 30 to the liquid pipe 70, the guide conduction module 80 prevents the high-temperature liquid from flowing from the liquid pipe 70 into the heat dissipation module 50. This prevents the high-temperature liquid from entering the heat dissipation module 50 inside the electrical box 60 when heating is not required, thereby wasting energy.

[0058] Optional, Figure 5 This is a schematic diagram of the structure of another temperature compensation system provided by an embodiment of the present invention. Figure 5 . The reversing module 30 may include a three-way valve, and the control module 40 controls the flow route of the high-temperature liquid by controlling the working state of the three-way valve. When the temperature information is less than a preset threshold, the high-temperature liquid is transported to the heat dissipation module 50 through the three-way valve to achieve heating of the electrical box 60. When the temperature information is lower than the preset threshold, the three-way valve is controlled to output the high-temperature liquid to the liquid pipe 70. The heat dissipation module 70 may include a plate-type radiator, the input end of the plate-type radiator is connected to the first output end b of the reversing module 30, and the output end of the plate-type radiator is connected to the first end of the one-way conduction module 80. The plate-type radiator is arranged inside the electrical box 60 and can quickly release the heat of the high-temperature liquid into the interior of the electrical box 60, heating the electronic components inside the electrical box 60 and avoiding low-temperature failure. The one-way conduction module 80 may include a one-way valve. The one-way conduction function of the one-way valve can prevent the high-temperature liquid from entering the heat dissipation module 50 inside the electrical box 60 when the electrical box 60 does not need to be heated, thereby wasting energy.

[0059] The temperature compensation system provided by the embodiment of the present invention utilizes a detection module to detect the temperature information inside the electrical box in real time. When the temperature is low, the heat exchanger converts the waste heat gas generated by the compressor into a high-temperature liquid, which is transported to the heat dissipation module inside the electrical box through the reversing module to heat the electrical box, thereby providing the electrical box with a relatively stable temperature environment so that it is not affected by the external low-temperature environment, thereby preventing the electronic components inside the electrical box from failing due to low temperature and ensuring the normal operation of the air conditioner.

[0060] The embodiment of the present invention also provides a temperature compensation method. Figure 6This is a flow chart of a temperature compensation method provided by an embodiment of the present invention. This method can be applied to the temperature compensation system of any of the above embodiments of the present invention, that is, the temperature compensation method can be executed by a temperature compensation system provided by any of the above embodiments.

[0061] like Figure 6 As shown, the temperature compensation method provided by the embodiment of the present invention includes:

[0062] S110: Obtain temperature information inside the electrical box.

[0063] Specifically, before performing temperature compensation on the electrical box of an air conditioner, it is necessary to first obtain the temperature information inside the electrical box. A temperature sensor can be installed inside the electrical box to collect the temperature information inside the electrical box in real time, so that the temperature compensation can be performed based on the temperature information.

[0064] S120 , controlling the working state of the reversing module according to the temperature information to control the flow route of the output fluid of the waste heat output module; when the output fluid flows through the heat dissipation module, heating the interior of the electrical box.

[0065] Specifically, after obtaining temperature information from the air conditioning unit's electrical box, temperature compensation can be performed on the electrical box based on this temperature information. The temperature information can be used to control the operating state of the reversing module. Depending on the reversing module's operating state, the output fluid generated by the waste heat output module flows through different routes. When the electrical box needs to be heated, the control module controls the operating state of the reversing module, which then transfers the output fluid to the heat dissipation module, where it dissipates heat to heat the interior of the electrical box. When heating is no longer necessary, the control module controls the reversing module to direct the output fluid to the liquid pipe, allowing the output fluid to participate in the air conditioning system's circulation.

[0066] Optional, Figure 7 This is a flow chart of another temperature compensation method provided by an embodiment of the present invention. Figure 7 , a flow chart of the temperature compensation method provided by an embodiment of the present invention further includes:

[0067] S210: Obtain temperature information inside the electrical box.

[0068] S220: If the temperature information is less than a preset threshold, the input end of the reversing module is controlled to be connected to the first output end, and the output fluid is sent to the heat dissipation module through the first output end to heat the inside of the electrical box.

[0069] Specifically, after obtaining the temperature information inside the electrical box, a determination is made as to whether to heat the interior of the electrical box based on the relationship between the temperature information and a preset threshold. If the temperature information inside the electrical box is lower than the preset threshold, it indicates that the temperature inside the electrical box is low, and the electronic components inside the electrical box may fail due to low temperatures, necessitating heating of the interior of the electrical box. The operating state of the reversing module is then controlled so that the input and first output terminals of the reversing module are conductive, and the waste heat gas generated by the waste heat output module is transported to the heat dissipation module through the input and first output terminals of the reversing module. The output fluid dissipates heat through the heat dissipation module, thereby heating the interior of the electrical box, raising the temperature inside the electrical box, and preventing the electronic components inside the electrical box from failing due to low temperatures.

[0070] S230: If the temperature information is greater than or equal to the preset threshold, the input end of the reversing module is controlled to be connected to the second output end, and the output fluid is output through the second output end.

[0071] Specifically, after obtaining temperature information from the electrical box, if the temperature is greater than or equal to a preset threshold, indicating that the temperature inside the box will not cause low-temperature failure of electronic components and that heating is temporarily unnecessary, the control module then connects the input and second output terminals of the reversing module, allowing the output fluid generated by the waste heat output module to be directly delivered to the liquid pipe through the input and second output terminals of the reversing module. When heating of the electrical box is not required, the reversing module delivers the output fluid directly to the liquid pipe, bypassing the heat dissipation module for heat dissipation, allowing it to directly participate in the system circulation process of the air conditioning system.

[0072] An embodiment of the present invention provides a temperature compensation method, which first obtains temperature information inside the electrical box, and controls the working state of the reversing module based on the temperature information to control the flow route of the output fluid. When the electrical box needs to be heated, the reversing module transports the output fluid to the heat dissipation module to heat the interior of the electrical box, so that the electrical box is in a relatively stable temperature environment, so that it is not disturbed by the external low temperature environment, prevents the electronic components inside the electrical box from failing due to low temperature, and ensures the normal operation of the air conditioner.
