The water vapor is directed to the second evaporator through the heat dissipation fan, and is liquefied through the semiconductor refrigeration plate to form water droplets that flow out from the water outlet pipe. Due to the heat release of liquefaction, the heat is dissipated at the hot end through the radiator, and the cold end continues to liquefy the water vapor. At the same time, the heat dissipation fan can also achieve the purpose of heat dissipation. The hot air is discharged from the air outlet slot, reducing the humidity of the refrigerator.

[0005] The method of sucking the humid air flow inside the refrigeration room through the dehumidification device and using the cold end of the semiconductor refrigeration plate for condensation and dehumidification can reduce the humidity inside the refrigeration room. However, while the humid air flow flows to the dehumidification device, part of the humid air flow will also flow to the heat exchange air duct, causing frost on the evaporator, affecting the heat exchange of the evaporator, resulting in a poor cooling effect inside the refrigeration room, and affecting the storage effect of the refrigeration room.

[0036] Combination Figure 1-5As shown, in some embodiments, the refrigeration equipment includes: a refrigeration compartment 100, a refrigeration air duct 200 and a dehumidification air duct 300. The refrigeration air duct 200 is arranged at one side of the refrigeration compartment 100, and the air outlet 210 of the refrigeration air duct 200 is connected to the refrigeration compartment 100; the dehumidification air duct 300 is arranged at the return air side of the refrigeration air duct 200, the air inlet 310 of the dehumidification air duct 300 is connected to the refrigeration compartment 100, and the air outlet end of the dehumidification air duct 300 is connected to the return air end of the refrigeration air duct 200.

[0037] By using the refrigeration equipment provided by the embodiment of the present disclosure, the refrigeration compartment 100 is used to store food and other items that need to be refrigerated. The airflow in the refrigeration compartment 100 enters the refrigeration air duct 200 for heat exchange and then is blown into the refrigeration compartment 100 again from the air outlet 210, so as to maintain the low temperature environment inside the refrigeration compartment 100. A dehumidification air duct 300 is arranged on the return air side of the refrigeration air duct 200. The airflow in the refrigeration compartment 100 first enters the dehumidification air duct 300 through the air inlet 310 of the dehumidification air duct 300 for dehumidification. The dehumidified airflow then flows into the refrigeration air duct 200 for heat exchange and then is blown into the refrigeration compartment 100, thereby reducing the risk of frost inside the refrigeration air duct 200, ensuring the heat exchange performance of the refrigeration air duct 200, and improving the storage effect of the refrigeration compartment 100.

[0038] Optionally, the refrigeration device further includes a housing 400 and a door 500. The refrigeration compartment 100 is defined by the housing 400. The door 500 is disposed at an open side of the refrigeration compartment 100, and one side of the door 500 is rotatably connected to one side of the housing 400. In this way, the refrigeration compartment 100 can be closed or opened by the door 500. When taking in or placing food or other items, the door 500 can be rotated to open the refrigeration compartment 100. After the food is taken in or placed, the door 500 can be rotated again to close the refrigeration compartment 100, thereby improving the sealing performance of the refrigeration compartment 100 and reducing the leakage of the cooling capacity in the refrigeration compartment 100.

[0039] Optionally, the refrigeration duct 200 is arranged on the rear side wall of the refrigeration chamber 100 and is located inside the shell 400. In this way, the refrigeration duct 200 is arranged on the rear side wall of the refrigeration chamber 100, so that the refrigeration duct 200 can be hidden, and the arrangement of the refrigeration duct 200 does not affect the thickness of the left and right sides of the shell 400, which facilitates the foaming of the shell 400, so that the heat preservation performance of the shell 400 is better.

[0040] Optionally, the dehumidification air duct 300 is arranged on the rear side wall of the refrigeration compartment 100 and is located inside the housing 400. In this way, the dehumidification air duct 300 is also arranged on the rear side wall of the refrigeration compartment 100, and while the dehumidification air duct 300 is hidden, the arrangement of the dehumidification air duct 300 and the refrigeration air duct 200 is made more reasonable, and the dehumidification airflow in the dehumidification air duct 300 can flow into the refrigeration air duct 200 more smoothly.

[0041] Optionally, a plurality of air outlets 210 are provided, and the plurality of air outlets 210 are opened along the vertical side wall of the refrigeration air duct 200, respectively connecting to areas at different heights inside the refrigeration compartment 100. In this way, the cold air flow inside the refrigeration air duct 200 can be blown into the refrigeration compartment 100 through the plurality of air outlets 210 at the same time, and the air can be discharged at different heights inside the refrigeration compartment 100, and the temperature uniformity inside the refrigeration compartment 100 is better.

[0042] Optionally, the refrigeration equipment comprises a refrigerator. Like this, a refrigerator is a common equipment for storing food.

[0043] Optionally, the dehumidification air duct 300 is located below the refrigeration air duct 200, and the air inlet 310 of the dehumidification air duct 300 is located in the bottom area of ​​the refrigeration compartment 100. In this way, due to the natural sinking characteristics of the humid air flow, the air inlet 310 of the dehumidification air duct 300 is set in the bottom area of ​​the refrigeration compartment 100, and the humid air flow deposited in the bottom area of ​​the refrigeration compartment 100 can be sucked by the air inlet 310 of the dehumidification air duct 300, thereby reducing the humidity in the refrigeration compartment 100 and keeping the refrigeration compartment 100 dry. The dehumidification air duct 300 is arranged below the refrigeration air duct 200, so that the air outlet end of the dehumidification air duct 300 is connected with the return air end of the refrigeration air duct 200, so that the dehumidified air flow in the dehumidification air duct 300 can flow into the refrigeration air duct 200 more smoothly.

[0044] Optionally, the dehumidification air duct 300 and the refrigeration air duct 200 are both rectangular cavities, the thickness of the dehumidification air duct 300 is the same as the thickness of the refrigeration air duct 200 in the horizontal direction, and the dehumidification air duct 300 and the refrigeration air duct 200 are located in the same vertical plane. In this way, the refrigeration air duct 200 and the dehumidification air duct 300 occupy the same space in the horizontal direction, and the refrigeration air duct 200 and the dehumidification air duct 300 after installation can better cooperate, which facilitates the communication between the refrigeration air duct 200 and the dehumidification air duct 300.

[0045] Optionally, in the vertical direction, the sum of the lengths of the dehumidification air duct 300 and the refrigeration air duct 200 is equal to the length of the refrigeration compartment 100, and the air inlet 310 is located at the lower end area of ​​the vertical side wall of the dehumidification air duct 300. In this way, the air inlet 310 can better inhale the humid air flow at the bottom of the refrigeration compartment 100.

[0046] Optionally, the air outlet of the dehumidification air duct 300 is located at the upper end of the dehumidification air duct 300, and the air return end of the refrigeration air duct 200 is located at the lower end of the refrigeration air duct 200. In this way, the dehumidification air duct 300 inhales the humid air flow at the bottom of the refrigeration compartment 100 through the air inlet 310, and the humid air flow is dehumidified in the dehumidification air duct 300 and flows along the air outlet of the dehumidification air duct 300 to the air return end of the refrigeration air duct 200, thereby entering the refrigeration air duct 200 for heat exchange and then being blown out.

[0047] Optionally, an evaporation tube 320 is provided inside the dehumidification air duct 300, and the evaporation tube 320 is laid between the air inlet 310 and the air outlet of the dehumidification air duct 300. In this way, the dehumidification air duct 300 inhales the humid air flow in the refrigeration compartment 100 through the air inlet 310, and the moisture of the humid air flow is condensed by the evaporation tube 320 when it flows through the evaporation tube 320, thereby achieving a dehumidification effect, and the dehumidified air flow flows to the refrigeration air duct 200 through the air outlet for heat exchange.

[0048] Optionally, a dew point temperature sensor 380 is provided inside the air inlet 310. In this way, the dew point temperature at the air inlet 310 of the dehumidification air duct 300 can be detected by the dew point sensor, and then the temperature of the evaporation tube 320 is controlled to be lower than the dew point temperature according to the dew point temperature, so that the humid air flow passing through the evaporation tube 320 can be efficiently condensed and dehumidified.

[0049] Optionally, the heat exchange area formed by the evaporation tube 320 covers the flow surface of the dehumidification air duct 300. In this way, the heat exchange area formed by the evaporation tube 320 can block the flow surface of the dehumidification air duct 300, so that the humid air flow from the air inlet 310 to the air outlet in the dehumidification air duct 300 can all flow through the evaporation tube 320 for condensation and dehumidification, further improving the dehumidification effect, thereby reducing the humidity of the air flow flowing into the refrigeration air duct 200 and reducing the risk of frost in the refrigeration air duct 200.

[0050] Optionally, the evaporation tube 320 is composed of four rows of tube groups arranged front and back, each row of tube groups has four heat exchange tubes, the four heat exchange tubes are arranged from top to bottom and connected in sequence, and a flow gap is formed between adjacent heat exchange tubes, and the four rows of tube groups are connected in sequence from front to back, and a flow gap is also formed between adjacent tube groups. In this way, the heat exchange area of ​​the evaporation tube 320 is increased, so that the humid air flow passing through can be condensed and dehumidified more efficiently.

[0051] Optionally, an evaporator 220 is provided inside the refrigeration duct 200, and the evaporator 220 is a part of the refrigeration system of the refrigeration device. In this way, the evaporator 220 exchanges heat with the airflow in the refrigeration duct 200, so that the airflow is cooled to form a cold airflow, and the cold airflow is blown out from the air outlet 210 to the refrigeration room 100 to maintain a low temperature environment of the refrigeration room 100.

[0052] It can be understood that reducing the risk of frost formation on the refrigeration air duct 200 mentioned in the above embodiment actually refers to reducing the risk of frost formation on the evaporator 220 in the refrigeration air duct 200 .

[0053] It can be understood that the refrigeration system of the refrigeration equipment is composed of an evaporator 220, a first condenser 230, a first compressor 240, a throttling element and other equipment. The evaporator 220, the first compressor 240, the first condenser 230 and the throttling element are connected in sequence to form a circulation loop, thereby constituting the refrigeration system of the refrigeration equipment.

[0054] Optionally, a heat dissipation chamber 600 is further defined inside the housing 400, and the heat dissipation chamber 600 is provided with a heat dissipation port, and the first condenser 230 and the first compressor 240 are disposed in the heat dissipation chamber 600. In this way, the heat generated by the first condenser 230 and the first compressor 240 during operation is dissipated to the outside of the housing 400 through the heat dissipation port of the heat dissipation chamber 600, thereby maintaining the heat exchange balance of the refrigeration system.

[0055] Combination Figure 3 As shown, in one embodiment, the evaporation pipe 320 is connected to the refrigeration system of the refrigeration equipment. In this way, the evaporation pipe 320 of the dehumidification user is connected to the refrigeration system of the refrigeration equipment, and the evaporator 220 and the evaporator 220 share a refrigeration system, which reduces the cost.

[0056] Optionally, the evaporation tube 320 and the evaporator 220 are connected in parallel between the first condenser 230 and the first compressor 240. The refrigerant flowing out of the first condenser 230 can flow into the evaporator 220 and the evaporation tube 320 respectively to evaporate and absorb heat after throttling and reducing pressure. The refrigerant after evaporation and absorption of heat in the evaporator 220 and the evaporation tube 320 is gathered and flows into the first compressor 240 for compression. In this way, heat exchange refrigeration of the refrigeration duct 200 and condensation dehumidification of the dehumidification duct 300 can be achieved through one refrigeration system, reducing costs.

[0057] Optionally, a solenoid valve 250 is provided on the pipeline connecting the evaporation pipe 320 and the first condenser 230. In this way, the flow rate of the refrigerant from the first condenser 230 to the evaporation pipe 320 can be controlled by controlling the opening of the solenoid valve 250, so as to achieve reasonable distribution of the refrigerant and ensure the refrigeration effect of the refrigeration equipment while dehumidifying.

[0058] For example, by controlling the opening of the solenoid valve 250, the flow of the refrigerant from the first condenser 230 to the evaporation tube 320 can be controlled, thereby controlling the temperature of the evaporation tube 320. When the humidity inside the refrigeration room 100 is high, the risk of frost on the evaporator 220 is high, and the opening of the solenoid valve 250 can be controlled to increase, reduce the temperature of the evaporation tube 320, and increase the dehumidification amount. When the humidity inside the refrigeration room 100 is low, the risk of frost on the evaporator 220 is low, and the opening of the solenoid valve 250 can be controlled to decrease, or directly closed, to ensure the heat exchange effect of the evaporator 220, thereby ensuring the storage and preservation effect of the refrigeration equipment.

[0059] Combination Figure 4As shown, in another embodiment, the evaporator tube 320 has an independent dehumidification refrigeration system, and the evaporator tube 320 is connected to the dehumidification refrigeration system, and the dehumidification refrigeration system is independent of the refrigeration system of the refrigeration equipment. In this way, the evaporator tube 320 is connected to the independent dehumidification refrigeration system, and the dehumidification of the evaporator tube 320 does not need to allocate the refrigerant of the evaporator 220, and the amount of refrigerant in the evaporator tube 320 is more sufficient, which improves the dehumidification effect while ensuring the refrigeration effect of the refrigeration equipment and improving the storage and preservation effect of the refrigeration equipment.

[0060] It can be understood that the dehumidification refrigeration system is composed of the evaporator tube 320, the second condenser 330, the second compressor 340 and the throttling element, etc. The evaporator tube 320, the second compressor 340, the second condenser 330 and the throttling element are connected in sequence to form the dehumidification refrigeration system.

[0061] Optionally, the interior of the heat dissipation chamber 600 is divided into a first installation area and a second installation area, the first condenser 230 and the first compressor 240 are arranged in the first installation area, and the second condenser 330 and the second compressor 340 are arranged in the second installation area. In this way, the interior of the heat dissipation chamber 600 is divided into two installation areas, the first condenser 230 and the first compressor 240 in the refrigeration system of the refrigeration equipment are installed in the first installation area, and the second condenser 330 and the second compressor 340 in the dehumidification refrigeration system are installed in the second installation area, so as to reduce the heat dissipation interference between the refrigeration system and the dehumidification refrigeration system.

[0062] Optionally, a partition is provided between the first installation area and the second installation area. In this way, the heat dissipation interference between the two installation areas is further reduced by providing the partition, thereby ensuring the refrigeration effect of the refrigeration equipment and the dehumidification efficiency.

[0063] Combination Figure 2 As shown, in one embodiment, a first circulation fan 260 is provided inside the refrigeration air duct 200. Under the action of the first circulation fan 260, the air flow sucked into the refrigeration compartment 100 by the air inlet 310 of the dehumidification air duct 300 flows to the refrigeration air duct 200. In this way, the first circulation fan 260 inside the refrigeration air duct 200 is used to provide negative pressure for suction. Since the dehumidification air duct 300 is connected with the refrigeration air duct 200, the negative pressure in the refrigeration air duct 200 can act on the dehumidification air duct 300, so that the dehumidification air duct 300 can smoothly suck in the humid air flow for dehumidification, and the dehumidified air flow can smoothly flow into the refrigeration air duct 200 for heat exchange, thereby reducing the cost.

[0064] Optionally, a second circulation fan 350 is provided inside the dehumidification air duct 300. In this way, the second circulation fan 350 will also provide negative suction pressure when in operation, so that the dehumidification air duct 300 can better inhale the moist air flow for dehumidification. Under the action of the first circulation fan 260 and the second circulation fan 350, the air suction volume of the dehumidification air duct 300 is increased, the dehumidification efficiency is improved, and the air flow circulation efficiency is also improved, so that the refrigeration effect of the refrigeration air duct 200 is also improved.

[0065] Optionally, the second circulation fan 350 is disposed on the leeward side of the evaporation tube 320. In this way, the airflow passing through the second circulation fan 350 is dehumidified airflow, which reduces the risk of the second circulation fan 350 being corroded by the wet airflow and prolongs the service life of the second circulation fan 350.

[0066] Combination Figure 5 As shown, in one embodiment, a water receiving groove 360 ​​is provided at the bottom of the dehumidification air duct 300. In this way, the water receiving groove 360 ​​can receive the condensed water generated inside the dehumidification air duct 300, reducing the risk of condensed water leaking out and contaminating the refrigeration compartment 100.

[0067] Optionally, a drain pipe 370 is provided at the bottom of the water receiving tank 360, and the water outlet end of the drain pipe 370 extends to the top of the first condenser 230 of the refrigeration device. In this way, the condensed water in the water receiving tank 360 is guided to the first condenser 230 of the refrigeration device by providing the drain pipe 370, and the condensed water is sprayed on the first condenser 230, so that the dust on the first condenser 230 can be washed away, and the heat exchange efficiency of the first condenser 230 is improved, thereby improving the refrigeration effect of the refrigeration device.

[0068] Optionally, a water receiving tray 610 is provided at the bottom of the heat dissipation chamber 600, and the water receiving tray 610 is located below the first condenser 230. In this way, the condensed water sprayed onto the first condenser 230 can be received by the water receiving tray 610, thereby reducing the risk of leakage of the condensed water that flushes the first condenser 230. At the same time, the evaporation of the condensed water in the water receiving tray 610 can cool the heat dissipation chamber 600, thereby improving the heat dissipation effect.
