It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0023] like Figure 1 As shown, in one aspect, the embodiments of this application provide a refrigeration system 1, including a compressor 10, a condenser 20, an evaporator 30, a first four-way valve 40, a second four-way valve 50, and an electronically controlled radiator 60. The electronically controlled radiator 60 can be switched on and off according to actual needs, thereby effectively preventing heat dissipation objects such as the control devices of the electronic control module from being damaged by moisture or overheating.
[0024] The refrigeration system 1 can be used in refrigeration equipment such as air conditioners and refrigerators, and this application embodiment does not limit this. The compressor 10 has an exhaust port and an intake port, and the type of compressor 10 can be determined according to actual needs, and this application embodiment does not limit this.
[0025] The first four-way valve 40 has a first valve port 41, a second valve port 42, a third valve port 43, and a fourth valve port 44. The first valve port 41 is connected to the exhaust port, the second valve port 42 is connected to the suction port, and the third valve port 43 is connected to the condenser 20. The second four-way valve 50 has a fifth valve port 51, a sixth valve port, a seventh valve port, and an eighth valve port 54. The fifth valve port 51 is connected to the fourth valve port 44, the sixth valve port is connected to the evaporator 30, and the seventh valve port is connected to the connecting pipe between the third valve port 43 and the condenser 20.
[0026] The electronically controlled radiator 60 is used to dissipate heat from heat-dissipating objects such as control devices of an electronically controlled module, and has a first heat dissipation channel 61 and a second heat dissipation channel 62 that are isolated from each other. One end of the first heat dissipation channel 61 is connected to the connecting pipe between the condenser 20 and the evaporator 30, and the other end is connected to the eighth valve port 54. One end of the second heat dissipation channel 62 is connected to the connecting pipe between the condenser 20 and the first heat dissipation channel 61 and the evaporator 30, and the other end is connected to the third valve port 43.
[0027] like Figure 2 As shown, during the operation of the refrigeration system 1, if there is no risk of overheating in heat dissipation objects such as the control devices of the electronic control module, the first four-way valve 40 and the second four-way valve 50 can be controlled to be in normal refrigeration operation. This allows the refrigerant discharged from the compressor 10 to flow sequentially through the first valve port 41, the third valve port 43, the condenser 20, the evaporator 30, the sixth valve port, the fifth valve port 51, the fourth valve port 44, and the second valve port 42, utilizing refrigerant circulation for refrigeration to meet indoor cooling needs. At this time, the refrigerant does not flow through the electronically controlled radiator 60, preventing condensation from forming when the refrigerant flows through it. This avoids damage to heat dissipation objects such as the control devices of the electronic control module due to moisture and effectively ensures refrigeration comfort.
[0028] like Figure 3 As shown, if there is a risk of overheating in heat-dissipating objects such as the controllers of the electronic control module, the first four-way valve 40 and the second four-way valve 50 can be controlled to operate in a cooling and heat dissipation state. This allows part of the refrigerant discharged from the compressor 10 to flow through the first heat dissipation channel 61 and the second heat dissipation channel 62 of the electronic control radiator 60, thereby cooling the heat-dissipating objects such as the controllers of the electronic control module as the refrigerant flows through the electronic control radiator 60. Part of the refrigerant still flows through the evaporator 30 to meet the indoor cooling requirements. At this time, because the heat-dissipating objects such as the controllers of the electronic control module have a high temperature and generate a large amount of heat, the refrigerant can fully evaporate without producing condensate when flowing through the electronic control radiator 60, and can efficiently cool the heat-dissipating objects such as the controllers of the electronic control module, effectively preventing damage from moisture or overheating.
[0029] Compared with related technologies, the refrigeration system 1 provided in this application embodiment can, according to the actual heat dissipation needs of heat dissipation objects such as the controller of the electronic control module, prevent the refrigerant from flowing through the first heat dissipation channel 61 and the second heat dissipation channel 62 of the electronic control radiator 60 when there is no risk of overheating of the heat dissipation object, thus avoiding damage to the heat dissipation object due to moisture. When there is a risk of overheating of the heat dissipation object, the refrigerant is controlled to flow through the first heat dissipation channel 61 and the second heat dissipation channel 62 of the electronic control radiator 60, so as to efficiently cool and dissipate heat dissipation objects without causing condensation and moisture, effectively avoiding damage to heat dissipation objects such as the controller of the electronic control module due to moisture or overheating.
[0030] like Figure 2 As shown, in some embodiments, when the refrigeration system 1 is in normal refrigeration mode, the first valve port 41 and the third valve port 43 are connected, the second valve port 42 and the fourth valve port 44 are connected, the fifth valve port 51 and the sixth valve port are connected, and the seventh valve port and the eighth valve port 54 are connected. In this way, the refrigerant discharged from the compressor 10 flows sequentially through the first valve port 41, the third valve port 43, the condenser 20, the evaporator 30, the sixth valve port, the fifth valve port 51, the fourth valve port 44, and the second valve port 42, utilizing refrigerant circulation for refrigeration to meet the indoor cooling requirements.
[0031] like Figure 3 As shown, when the refrigeration system 1 is in the refrigeration and heat dissipation state, the first valve port 41 and the fourth valve port 44 are connected, the second valve port 42 and the third valve port 43 are connected, the fifth valve port 51 and the seventh valve port are connected, and the sixth valve port and the eighth valve port 54 are connected. In this way, the refrigerant discharged from the compressor 10 flows sequentially through the first valve port 41, the fourth valve port 44, the fifth valve port 51, and the seventh valve port before flowing through the condenser 20. After flowing through the condenser 20, it splits into two refrigerant streams, namely the first refrigerant stream and the second refrigerant stream. The first refrigerant stream flows sequentially through the first refrigerant channel, the sixth valve port, the seventh valve port, and the evaporator 30, thereby cooling heat dissipation on heat-generating objects such as the control devices of the electronic control module while flowing through the first refrigerant channel. After flowing out of the evaporator 30, it merges with the second refrigerant stream. The merged refrigerant stream flows through the second refrigerant channel, passes through the third valve port 43 and the second valve port 42, and returns to the suction port of the compressor 10 to complete the refrigerant cycle. While flowing through the second refrigerant channel, it again cools heat dissipation on heat-generating objects such as the control devices of the electronic control module, thereby enhancing the cooling effect.
[0032] In some examples, the refrigeration system 1 may include a main throttle valve 70, which is disposed on the connecting pipe between the condenser 20 and the evaporator 30 to throttle the refrigerant before it enters the evaporator 30.
[0033] For example, the main throttle valve 70 can be installed on the connecting pipe between the condenser 20 and the first heat dissipation channel 61 and the evaporator 30. The refrigeration system 1 includes a bypass throttle valve 80, which is installed on the connecting pipe between the first heat dissipation channel 61 and the eighth valve port 54, for throttling the refrigerant flowing out of the first heat dissipation channel 61.
[0034] For example, the electronically controlled radiator 60 can be used to dissipate heat from the electronically controlled module, which in turn controls the refrigeration system 1. For example, when the refrigeration system 1 is in a cooling state, the opening of the main throttle valve 70 can be negatively correlated with the temperature of the electronically controlled module. For instance, when the temperature of the electronically controlled module is high, the opening of the main throttle valve 70 can be set smaller to increase the cooling capacity of the refrigerant flowing through the electronically controlled radiator 60, thereby improving the heat dissipation effect of the radiator 60 on the electronically controlled module and quickly reducing the temperature of the electronically controlled module. When the temperature of the electronically controlled module is low, the opening of the main throttle valve 70 can be set larger to control the cooling capacity of the refrigerant flowing through the radiator 60 at a more suitable level, ensuring both the heat dissipation effect of the radiator 60 on the electronically controlled module and the cooling effect of the refrigeration system 1.
[0035] For example, the electronic control heat sink 60 may be provided with heat dissipation fins (not shown in the figure). Here, the heat dissipation fins can be connected to the electronic control module to absorb the heat generated when the electronic control module is working, and the heat dissipation fins can exchange heat with the air to dissipate the absorbed heat into the air, so as to dissipate heat from the electronic control module through air cooling heat exchange.
[0036] In some embodiments, at least one of the first heat dissipation channel 61 and the second heat dissipation channel 62 may have a curved channel structure. Utilizing a curved channel structure can increase the heat exchange area of the heat dissipation channel, thereby increasing the heat dissipation effect of the electronically controlled heat sink 60 on the electronically controlled module. In some examples, the first heat dissipation channel 61 may have a curved channel structure, and the second heat dissipation channel 62 may have a straight channel structure; in other examples, the first heat dissipation channel 61 may have a straight channel structure, and the second heat dissipation channel 62 may have a curved channel structure; in still other examples, both the first heat dissipation channel 61 and the second heat dissipation channel 62 may have a curved channel structure. The shape of the curved channel structure can be determined according to actual needs and may be, for example, serpentine, arc-shaped, or other curved shapes; this embodiment does not limit this.
[0037] In some embodiments, the refrigeration system 1 may include a gas-liquid separator 90, which is disposed between the suction port and the second valve port 42 of the compressor 10. By providing the gas-liquid separator 90, gaseous refrigerant and liquid refrigerant can be separated, preventing liquid refrigerant from entering the compressor 10 and avoiding the risk of liquid slugging.
[0038] On the other hand, this application provides an air conditioner that includes a refrigeration system 1 and an electronic control module, as described in any of the above embodiments. The electronic control module is used to control the refrigeration system 1. The type of air conditioner can be determined according to actual needs, and may be, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling-mounted air conditioner, etc. This application does not limit this type. The air conditioner provided in this application has the aforementioned refrigeration system 1, and can control the on / off switching of the electronically controlled radiator 60 according to actual needs, thereby effectively preventing damage to heat-dissipating objects such as the control components of the electronic control module from moisture or overheating.
[0039] The refrigeration system and air conditioner provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
