[0045] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0047] The refrigeration system 10 for refrigeration equipment provided in the embodiment of the present disclosure is as follows: Figures 1 to 6 As shown, the refrigeration system 10 for refrigeration equipment includes: a first air duct 100, a first fan 200, an evaporator 300 and a defrost module 400. The first air duct 100 is connected to the compartment of the refrigeration equipment 700. The first fan 200 is arranged in the first air duct 100, and is used to send the air in the first air duct 100 to the air outlet of the first air duct 100. The evaporator 300 is arranged in the first air duct 100. The defrost module 400 is arranged close to the evaporator 300. In the defrosting stage, the inner side of the defrost module 400 close to the evaporator 300 is used to generate heat, and the outer side of the defrost module 400 away from the evaporator 300 is used to generate cold.

[0048] Specifically, the refrigeration device is a refrigerator, a freezer or other equipment used to keep items fresh.

[0049] It is understandable that the refrigeration system 10 for the refrigeration device 700 also includes a compressor and a condenser, the outlet of the compressor is connected to the inlet of the condenser, the outlet of the condenser is connected to the inlet of the evaporator 300, and the outlet of the evaporator 300 is connected to the inlet of the compressor.

[0050] Specifically, by arranging the first fan 200 and the evaporator 300 in the first air duct 100 connected to the compartment, the cold energy generated by the evaporator 300 can be blown into the compartment through the first air duct 100 by controlling the operation of the first fan 200, so that the compartment can realize the refrigeration function or the freezing function.

[0051] Specifically, the defrost module 400 is arranged close to the evaporator 300, and the inner side of the defrost module 400 that can generate heat is arranged close to the evaporator 300, and the outer side of the defrost module 400 that can generate cold is arranged away from the evaporator 300. It is achieved that the evaporator 300 is defrosted through the inner side of the defrost module 400, and the cold in the room is supplemented through the outer side of the defrost module 400 during the defrosting stage.

[0052] In the disclosed embodiment, during the defrosting stage, the evaporator 300 can be defrosted by the heat generated by the inner side of the defrosting module 400. And because the outer side of the defrosting module 400 can generate cold energy, the first fan 200 can still keep running to send the cold energy generated by the outer side of the defrosting module 400 into the compartment. In this way, the temperature fluctuation in the compartment during the defrosting stage is reduced, so that the temperature in the compartment is always stable within a certain range, and the storage effect of the items stored in the compartment is improved.

[0053] like Figure 2 As shown, in some embodiments, the defrost module 400 includes: a semiconductor cooling sheet 410 and a heat insulation board (not shown in the figure). The hot end of the semiconductor cooling sheet 410 is arranged close to the evaporator 300, and the cold end of the semiconductor cooling sheet 410 is arranged away from the evaporator 300. The heat insulation board is arranged between the hot end and the cold end of the semiconductor cooling sheet 410.

[0054] Specifically, the semiconductor cooling sheet 410 is a component made of two different semiconductor materials that can form a Peltier effect. When direct current passes through a galvanic couple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the galvanic couple respectively. During the defrosting stage of the evaporator 300, the outer side of the defrost module 400 needs to generate cold, and the inner side of the defrost module 400 needs to generate heat. Therefore, semiconductor refrigeration can be used as the defrost module 400. And it is necessary to set the hot end of the semiconductor cooling sheet 410 close to the evaporator 300, and set the cold end of the semiconductor cooling sheet 410 away from the evaporator 300.

[0055] Specifically, by providing a heat insulation board between the hot end and the cold end of the semiconductor cooling plate 410, the cold end and the hot end of the semiconductor cooling plate 410 can be physically partitioned, reducing the consumption of cold and heat offsetting each other. In this way, the defrosting effect of the defrosting module 400 on the evaporator 300 is improved, and the effect of maintaining the compartment temperature by cold is improved.

[0056] In the embodiment of the present disclosure, the semiconductor cooling sheet 410 is used as the defrosting module 400, so when the direct current passes through the thermocouple of the semiconductor cooling sheet 410, heat can be absorbed and released at both ends of the thermocouple respectively. In this way, the defrosting of the evaporator 300 is achieved, and the temperature inside the room is maintained.

[0057] In the embodiment of the present disclosure, a heat insulation plate is provided between the hot end and the cold end of the semiconductor cooling plate 410 to reduce the consumption of cold and heat offsetting each other.

[0058] like Figure 2As shown, the defrost module 400 further includes a hot end radiator 420, a cooling fan and a cold end radiator 440. The hot end radiator 420 is arranged at the hot end side of the semiconductor cooling sheet 410, and is used to accelerate the heat dissipation to the evaporator 300. The cooling fan is arranged at the hot end radiator 420 and faces the evaporator 300. The cold end radiator 440 is arranged at the cold end side of the semiconductor cooling sheet 410, and is used to accelerate the dissipation of cold.

[0059] Specifically, by arranging the hot end heat sink 420 at the hot end side of the semiconductor cooling sheet 410, the speed of heat dissipation to the evaporator 300 can be accelerated. In this way, the time required for the evaporator 300 to defrost is shortened.

[0060] Specifically, by arranging a heat dissipation fan 430 on the hot end heat sink 420 and on a side facing the evaporator 300, when the heat dissipation fan 430 is running, heat can be evenly blown to the surface of the evaporator 300. In this way, the time required for defrosting the evaporator 300 is further shortened, and the effect of defrosting the evaporator 300 is improved.

[0061] Specifically, by arranging a cold end radiator 440 on the cold end side of the semiconductor cooling sheet 410, the speed of dissipating cold energy into the air duct can be accelerated. In this way, during the defrosting stage of the evaporator 300, more cold energy can flow into the room of the refrigeration device 700, thereby improving the effect of maintaining the temperature in the room during the defrosting stage and improving the preservation effect of the items stored in the room during the defrosting stage.

[0062] In the embodiment of the present disclosure, by providing the hot end radiator 420 and the heat dissipation fan 430, the heat is quickly convected and evenly distributed on the evaporator 300, thereby accelerating the defrosting speed of the evaporator 300. By providing the cold end radiator 440, the cold energy can be dissipated to the air duct more quickly, thereby ensuring the stability of the indoor temperature during the defrosting stage.

[0063] In some embodiments, the number of the defrost modules 400 is two, and the two defrost modules 400 are disposed oppositely on two sides of the evaporator 300 .

[0064] Specifically, by arranging the defrosting modules 400 on both sides of the evaporator 300, when the evaporator 300 is defrosted, both sides of the evaporator 300 receive heat. In this way, the heat is more evenly distributed on the surface of the evaporator 300, the defrosting effect of the evaporator 300 is improved, the defrosting speed of the evaporator 300 is accelerated, and the time required for the evaporator 300 to defrost is shortened.

[0065] Specifically, by arranging the defrost modules 400 on both sides of the evaporator 300, when the evaporator 300 is defrosted, the cold amount dissipated into the air duct by arranging two defrost modules 400 is greater than the cold amount dissipated into the air duct by arranging one defrost module 400. This allows more cold amount to flow into the compartment, ensuring the stability of the indoor temperature during the defrosting stage.

[0066] like Figure 2 As shown, in some embodiments, the refrigeration system 10 for the refrigeration device 700 further includes a first water receiving tray 450 and a first heater 460. The first water receiving tray 450 is disposed at the bottom of the evaporator 300 and the defrost module 400, and is used to receive defrosted water or defrosted ice cubes. The first heater 460 is disposed in the first water receiving tray 450.

[0067] It is understandable that during the defrosting process of the evaporator 300, defrosting water or defrosting ice cubes will appear at the bottom of the evaporator 300. Therefore, in the embodiment of the present disclosure, a first water receiving tray 450 for receiving defrosting water and defrosting ice cubes is provided at the bottom of the evaporator 300 and the defrosting module 400. In this way, it is possible to prevent the defrosting water or defrosting ice cubes from falling into the air duct, causing the humidity of the air circulating in the air duct to increase, thereby causing the humidity in the room to increase.

[0068] Specifically, by arranging the first heater 460 in the first water receiving tray 450, the defrosted water or defrosted ice cubes in the first water receiving tray 450 can be evaporated under the action of the first heater 460. In this way, the user does not need to manually process the defrosted water or defrosted ice cubes in the first water receiving tray 450.

[0069] It is understandable that an evaporation dish is usually provided in the refrigeration device 700, and therefore, the first water receiving tray 450 can be connected to the evaporation dish of the refrigeration device 700 through a drain pipe. In this way, the defrost water collected in the first water receiving tray 450 can flow into the evaporation dish, so that the user does not need to manually process the defrost water in the first water receiving tray 450.

[0070] Specifically, when the first water receiving tray 450 is connected to the evaporation dish of the refrigeration device 700 through the drain pipe, the defrosted ice cubes generated by defrosting may cause the drain outlet of the first water receiving tray 450 to be blocked. In this case, the first heater 460 can be started to heat the defrosted ice cubes in the first water receiving tray 450. In this way, the risk of the defrosted ice cubes blocking the drain outlet of the first water receiving tray 450, resulting in the inability to discharge the defrosted water, is reduced.

[0071] In the embodiment of the present disclosure, by providing the first water receiving tray 450, defrosted water or defrosted ice cubes are prevented from flowing into the air duct, thereby reducing the risk of humidity increase in the room. By providing the first heater 460, the defrosted water and defrosted ice cubes are evaporated, or the risk of clogging the drain outlet of the first water receiving tray 450 is reduced.

[0072] like Figure 3 As shown, in some embodiments, the refrigeration system 10 for the refrigeration device 700 further includes an auxiliary humidification module 500. The auxiliary humidification module 500 is disposed in the first air duct 100, and the auxiliary humidification module 500 is closer to the air outlet of the first air duct 100 than the evaporator 300. When the humidity in the compartment is lower than the set humidity, the auxiliary humidification module 500 is used to humidify the compartment.

[0073] Specifically, by arranging the auxiliary humidification module 500 in the first air duct 100, when the humidity in the compartment is lower than the set humidity, the air in the air duct can be humidified by the auxiliary humidification module 500. The humidification process in the compartment is realized, the stability of the humidity in the compartment is ensured, and the storage effect of the refrigeration device 700 on the items is improved.

[0074] Specifically, by arranging the auxiliary humidification module 500 closer to the air outlet of the first air duct 100 than the evaporator 300, it is possible to prevent the air humidified by the auxiliary humidification module 500 from flowing toward the evaporator 300. Since the humid air flowing toward the evaporator 300 in the cooling state is likely to cause frost on the surface of the evaporator 300, the risk of frost on the evaporator 300 can be reduced through the above arrangement.

[0075] In the embodiment of the present disclosure, by arranging the auxiliary humidification module 500 at a position closer to the air outlet of the first air duct 100 than the evaporator 300, the stability of the humidity in the compartment is ensured and the risk of frosting of the evaporator 300 when humidifying the compartment is reduced.

[0076] like Figure 3 As shown, the auxiliary humidification module 500 includes a wet film assembly 510, a blowing assembly and a second water receiving tray 530. The wet film assembly 510 is used to humidify the air flowing through; the blowing assembly is arranged on the side of the wet film assembly 510 away from the air outlet, and is used to blow the humidified air along the air outlet of the first air duct 100 to the compartment. The second water receiving tray 530 is arranged at the lower part of the wet film assembly 510.

[0077] Specifically, the air in the air duct is humidified by providing the wet film assembly 510. By providing a blowing assembly on the side of the wet film assembly 510 away from the air outlet, the air in the air duct can be evenly blown toward the wet film assembly 510, thereby accelerating the evaporation rate of water in the wet film of the wet film assembly 510 and improving the humidification effect of the wet film assembly 510 on the air.

[0078] It is understandable that, in the process of starting the auxiliary humidification module 500 to perform humidification treatment in the compartment, water may drip from the bottom of the wet membrane assembly 510. Therefore, in the embodiment of the present disclosure, a second water receiving tray 530 is provided at the bottom of the wet membrane assembly 510. In this way, water dripping from the humidity assembly is prevented from falling into the first air duct 100.

[0079] In the embodiment of the present disclosure, by providing the wet film assembly 510 and the blowing assembly, the air in the first air duct 100 can be humidified by the wet film assembly 510 and then blown into the compartment along the air outlet of the first air duct 100, thereby adjusting the humidity in the compartment, so that the humidity in the compartment can always be maintained at a humidity suitable for storing items, thereby improving the storage effect of the compartment on items.

[0080] like Figure 4 As shown, the wet membrane assembly 510 includes a honeycomb wet membrane 511, a water outlet pipe 512 and a guide plate 513. The water outlet pipe 512 is arranged on the upper part of the honeycomb wet membrane 511, and a plurality of water outlets are evenly arranged along the length direction of the water outlet pipe 512. The guide plate 513 is arranged on the upper part of the water outlet pipe 512, and is used to guide the water flowing out of the plurality of water outlets to the wet membrane.

[0081] Specifically, by arranging the water outlet pipe 512 on the upper part of the honeycomb wet membrane 511, a plurality of water outlets are evenly opened along the length direction of the water outlet pipe 512, and a guide plate 513 is arranged above the water outlet. The water flowing out of the water outlet pipe 512 can flow evenly onto the honeycomb wet membrane 511 under the action of the guide plate 513, and can flow downward along the honeycomb wet membrane 511. In this way, the uniformity of water distribution on the honeycomb wet membrane 511 is ensured, and the humidification effect of the wet membrane assembly 510 on the air is improved.

[0082] Optionally, the guide plate 513 is an arc-shaped groove structure.

[0083] Specifically, the guide plate 513 is configured as an arc-shaped groove structure, which can further improve the uniformity of water flowing onto the honeycomb wet membrane 511 .

[0084] In the embodiment of the present disclosure, by setting the water outlet pipe 512 on the upper part of the honeycomb wet membrane 511 and setting the guide plate 513 above the water outlet of the water outlet pipe 512, the uniformity of water distribution in the honeycomb wet membrane 511 is improved, and the humidification effect of the wet membrane assembly 510 on the air is improved.

[0085] like Figure 5 As shown, in some embodiments, the blowing assembly includes a second air duct 521 and a second fan 522. The second air duct 521 includes a main air duct 5211 and a plurality of sub-air ducts 5212, the plurality of sub-air ducts 5212 are connected to the main air duct 5211, the plurality of sub-air ducts 5212 are arranged in a matrix, and a plurality of air outlets are evenly arranged on each sub-air duct 5212. The second fan 522 is arranged in the main air duct 5211, and is used to make the wind blow evenly toward the wet film assembly 510 through the plurality of air outlets.

[0086] Specifically, by arranging the second fan 522 in the main air duct 5211 of the second air duct 521, connecting the plurality of sub-air ducts 5212 of the second air duct 521 with the main air duct 5211, and arranging the plurality of sub-air ducts 5212 in a matrix, the wind blown out by the second fan 522 can be evenly blown toward the wet film assembly 510 through the air outlets on the plurality of sub-air ducts 5212. In this way, the contact area between the air and the wet film assembly 510 is increased, and the humidification effect and efficiency of the wet film assembly 510 on the air is improved.

[0087] Optionally, there are multiple second fans 522 .

[0088] Specifically, by arranging a plurality of second fans 522 in the main air duct 5211, the uniformity and strength of the wind from the air supply assembly 520 to the wet membrane assembly 510 can be further improved, which is conducive to improving the humidification effect of the wet membrane assembly 510 on the air.

[0089] like Figure 6 As shown, in some embodiments, the refrigeration system 10 for the refrigeration device 700 further includes a second heater 600. The second heater 600 is disposed between the evaporator 300 and the auxiliary humidification module 500.

[0090] Specifically, by arranging the second heater 600 between the evaporator 300 and the auxiliary humidification module 500, when the auxiliary humidification module 500 is used to humidify the interior of the compartment, the second heater 600 can be started to prevent the humid air from flowing to the evaporator 300. In this way, the risk of frosting of the evaporator 300 is reduced when the compartment is humidified.

[0091] Combination Figure 7 As shown, the refrigeration device 700 provided in the embodiment of the present disclosure includes a device body 710 and the refrigeration system 10 for the refrigeration device as described above.
