Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration, in particular to refrigeration equipment and control methods. Background Art

[0002] At present, with the improvement of people's living standards, the demand for red wine and cigars has increased. Red wine and cigars have strict requirements for storage temperature and humidity. Temperatures and humidity outside the standard range will directly affect their taste and texture. Currently, the wine cabinets or cigar cabinets on the market adopt direct refrigeration methods and cannot accurately control the evaporation temperature. Due to the start and stop of the compressor, the temperature fluctuates greatly, which in turn leads to large fluctuations in the humidity inside the cabinet. When the humidity is too low, the cork of the red wine is prone to cracking, and air enters the wine bottle, resulting in the oxidation and deterioration of the stored wine. When the humidity is too high, the cork is prone to mildew, causing damage to the wine. For cigars, too low humidity will cause the wrapper to crack, and too high humidity will cause the cigars to mildew. To solve this problem, the common method in the prior art is to reduce the temperature difference between the on and off points of the temperature sensor, but this will cause the compressor to start and stop frequently, resulting in relatively increased energy consumption. In addition, it has a greater impact on the reliability of the compressor and shortens its service life. In addition, when the compressor is working for refrigeration, due to the condensation of moisture in the cabinet on the evaporator, the humidity in the storage compartment drops rapidly, and the humidity controllability is poor. Therefore, it is necessary to study a refrigeration device and a control method to solve the above problems. Summary of the Invention

[0051] The following elaborates on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0052] The terms "including" and "having" and any variations thereof in the present invention are intended to cover non-exclusive inclusion. Mentioning "embodiment" in this article means that the specific features, structures or characteristics described in conjunction with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0053] Combined with Figure 1As shown, the present invention mainly relates to: a refrigeration device, which includes a box body 1. The box body 1 includes an inner liner 11, and the inner liner 11 defines a storage compartment 12. The inner liner 11 includes an inner liner rear wall 13. The refrigeration device in this embodiment is explained by taking a refrigerator as an example. The inner liner 11 also includes an inner liner opening, and the inner liner opening is disposed opposite to the inner liner rear wall 13.

[0054] Preferably, the refrigeration device is configured as a refrigerator for storing red wine and / or cigars.

[0055] Combined with Figure 2 and Figure 3 As shown, in this embodiment, the refrigeration device further includes a heat-conducting partition 2 disposed in the inner liner 11. One side of the heat-conducting partition 2 forms the storage compartment 12. The other side of the heat-conducting partition 2 includes a cooling chamber 35.

[0056] Furthermore, the refrigeration device further includes a plate evaporator 3 disposed between the heat-conducting partition 2 and the inner liner rear wall 13. The plate evaporator 3 and the heat-conducting partition 2 are sequentially spaced apart in the direction from back to front.

[0057] A cooling chamber 35 is defined between the plate evaporator 3 and the inner liner rear wall 13, and a cold air circulation chamber 25 communicating with the cooling chamber 35 is defined between the plate evaporator 3 and the heat-conducting partition 2. A fan 4 is disposed in the cooling chamber 35 or the cold air circulation chamber 25. The other side of the heat-conducting partition 2 includes the cooling chamber 35 and the cold air circulation chamber 25. The cold quantity generated by the plate evaporator 3 enters the cold air circulation chamber 25 in the form of cold air under the promotion of the fan 4 and conducts the cold quantity to the heat-conducting partition 2. After the cold air exchanges heat with the heat-conducting partition 2, it becomes hot air and then enters the cooling chamber 35 to exchange heat with the plate evaporator 3 to become cold air, thereby completing the refrigeration cycle.

[0058] Wherein, at least a part of the heat-conducting partition 2 is exposed in the storage compartment 12, so that the cold quantity of the plate evaporator 3 is radiated into the storage compartment 12 through the heat-conducting partition 2. The cold quantity on the heat-conducting partition 2 exchanges heat with the heat load in the storage compartment 12, thereby achieving the purpose of cooling the storage compartment 12.

[0059] In this embodiment, the refrigeration equipment provided divides the space between the heat conduction partition plate 2 and the inner container 11 into a cooling chamber 35 and a cold air circulation chamber 25 through the plate evaporator 3. The plate evaporator 3 serves as a heat exchange component to provide cold air for the storage room 12, and at the same time serves as the partition wall between the cooling chamber 35 and the cold air circulation chamber 25, enhancing the heat exchange efficiency while improving the space utilization rate and reducing the cost. A blower 4 is provided in the cooling chamber 35 or the cold air circulation chamber 25. The cold air generated by the plate evaporator 3 enters the cold air circulation chamber 25 in the form of cold air under the promotion of the blower 4 and conducts the cold air to the heat conduction partition plate 2. The heat conduction partition plate 2 radiates and transfers the cold air to the air in the storage room 12 to complete the refrigeration of the storage room 12. After the cold air exchanges heat with the heat conduction partition plate 2, it becomes hot air and then enters the cooling chamber 35 to exchange heat with the plate evaporator 3 to become cold air, thus completing the refrigeration cycle. Since the dry cold air in the cooling chamber 35 does not enter the storage room 12 and the storage room 12 is no longer refrigerated by the forced circulation of low-temperature cold air, the moisture in the storage room 12 will not be taken away, which is beneficial to controlling the humidity in the storage room 12, and has the advantages of high refrigeration efficiency, controllable humidity, high space utilization rate, and compact structure.

[0060] Combined with Figure 4 As shown, in this embodiment, the plate evaporator 3 includes an evaporation plate 31 arranged parallel to the rear wall 13 of the inner container and a refrigeration pipeline 32 arranged on the evaporation plate 31. The cooling chamber 35 and the cold air circulation chamber 25 are respectively communicated at the upper and lower ends of the evaporation plate 31. Specifically, intervals are respectively provided between the upper and lower ends of the evaporation plate 31 and the inner wall of the inner container 11, so that there are preset intervals between the upper and lower ends of the evaporation plate 31 and the inner wall of the inner container 11. Or, through holes communicating the cooling chamber 35 and the cold air circulation chamber 25 are respectively provided at the upper and lower ends of the evaporation plate 31.

[0061] Preferably, the plate evaporator 3 is set as a blown evaporator.

[0062] Furthermore, an air return port 33 flowing from the cold air circulation chamber 25 to the cooling chamber 35 is formed above the evaporation plate 31, and an air inlet 34 flowing from the cooling chamber 35 to the cold air circulation chamber 25 is formed below the evaporation plate 31. Among them, the cold air in the cooling chamber 35 enters the cold air circulation chamber 25 from the air inlet 34 and flows upward, and then enters the cooling chamber 35 through the air return port 33 and flows downward to the air inlet 34. Thus, the cold air circulation between the cold air circulation chamber 25 and the cooling chamber 35 is completed.

[0063] The blower 4 is arranged at the position of the air inlet 34. The blower 4 sucks the cold air in the cooling chamber 35 through the air inlet 34 and discharges it upward.

[0064] Combined with Figure 3 、 Figure 4As shown, further, the refrigeration device further includes an air duct plate 36 cooperatively arranged with the evaporation plate 31. The air duct plate 36 extends downward from a position near the lower end of the evaporation plate 31, and together with the evaporation plate 31, separates the cooling chamber 35 and the cold air circulation chamber 25. An air inlet 34 is formed on the air duct plate 36. The air duct plate 36 includes a vertical portion extending upward from the bottom to a position near the lower end of the evaporation plate 31 and a horizontal portion formed by bending the vertical plate backward.

[0065] The shape of the air inlet 34 is adapted to the shape of the fan 4 and is set as a circle.

[0066] Further, the fan 4 is fixedly mounted forward on the heat conduction partition plate 2. The fan 4 includes a fan and a fan housing for mounting the fan. The fan housing is fixed to the heat conduction partition plate 2 through fasteners.

[0067] The fan 4 has a suction port 41 opposite to the air inlet 34 and an air outlet 42 opening toward the cold air circulation chamber 25. The suction port 41 of the fan 4 sucks the cold air in the cooling chamber 35 through the air inlet 34 and discharges it upward through the air outlet 42.

[0068] Further, the heat conduction partition plate 2 includes a partition body 21 and a plurality of flow dividing guide plates 22 extending backward from the partition body 21. The fan 4 is fixed to the rear wall of the partition body 21 and is arranged at the bottom of the flow dividing guide plates 22.

[0069] Combined Figure 5 As shown, in this embodiment, further, the heat conduction partition plate 2 further includes an arc-shaped air guide plate 24 extending backward from the partition body 21 for mounting the fan 4. The arc-shaped air guide plate 24 defines an arc space for mounting the fan 4. Preferably, the air outlet 42 is arranged upward.

[0070] Wherein, the lower end surfaces of the plurality of flow dividing guide plates 22 are arranged at the upper end opening of the arc space.

[0071] A flow dividing air duct 23 extending upward from the air outlet 42 of the fan 4 is defined between two adjacent flow dividing guide plates 22. The fan 4 sucks the cold air in the cooling chamber 35 through the air inlet 34 and discharges it upward through the plurality of flow dividing air ducts 23, so as to ensure that the cold quantity distribution of the heat conduction partition plate 2 is relatively uniform, increase the contact area between the cold air and the heat conduction partition plate 2, enhance the radiation quantity and radiation efficiency of the cold quantity of the heat conduction partition plate 2, and avoid waste of cold air. It has the advantages of energy saving, high efficiency and high refrigeration efficiency.

[0072] Further, a gap is preset between the evaporation plate 31 and the flow dividing guide plates 22 and the air duct plate 36 respectively, so that the defrosting water generated when the plate evaporator 3 defrosts flows downward along the evaporation plate 31 and is discharged.

[0073] Preferably, the size range of the gap is below 5 mm, minimizing the occupied space as much as possible to improve the space utilization rate.

[0074] Furthermore, the evaporation plate 31 is fixed to the inner container 11 through fasteners.

[0075] Furthermore, the refrigeration device further includes a turbulent flow air duct 51 disposed at least partially adjacent to the heat conduction partition 2, a turbulent flow fan 4 disposed in the turbulent flow air duct 51, a turbulent flow air outlet 52, and a turbulent flow air return port 53.

[0076] Among them, the turbulent flow air outlet 52 and the turbulent flow air return port 53 are respectively communicated with the turbulent flow air duct 51 and the storage compartment 12. The turbulent flow air duct 51 enables the cold air in the storage compartment 12 to circulate, which is beneficial to ensuring the temperature uniformity in the storage compartment 12.

[0077] Furthermore, the heat conduction partition 2 includes a heat conduction partition body 21 and a fixing portion formed by the backward extension of the heat conduction partition body 21 and clamped with the rear wall in a limiting manner;

[0078] The fixing portion includes a limiting abutting plate and a hook disposed at the rear side of the limiting abutting plate.

[0079] The rear wall includes an abutting and cooperating portion cooperating with the limiting abutting plate and a clamping groove cooperating with the hook.

[0080] Furthermore, the turbulent flow air duct 51 includes a first air duct 511 disposed at the bottom of the inner container 11 and used for accommodating the turbulent flow fan 4, and a second air duct 512 extending upward from the first air duct 511 and disposed adjacent to the heat conduction partition 2. The first air duct 511 and the second air duct 512 are communicated with each other.

[0081] Among them, the turbulent flow air outlet 52 is communicated with the second air duct 512, and the turbulent flow air return port 53 is communicated with the first air duct 511. The turbulent flow air return port 53 is disposed at the bottom of the storage compartment 12, and the air returns through the turbulent flow air return port 53 at the bottom of the storage compartment 12. A turbulent flow air path with upper air outlet and bottom air return is formed. The hot air entering the turbulent flow air duct 51 from the turbulent flow air return port 53 at the bottom of the storage compartment 12 fully contacts and exchanges heat with the heat conduction partition 2 from bottom to top, becomes cold air and then enters the storage compartment 12 through the turbulent flow air outlet 52. The cold air naturally sinks and then passes through the turbulent flow air return port 53, having the advantages of reasonable turbulent flow path setting and high refrigeration efficiency.

[0082] Furthermore, the refrigeration device further includes a turbulent flow guide plate 55 disposed on the side of the heat conduction partition 2 close to the storage compartment 12.

[0083] A second air duct 512 is defined between the spoiler guide plate 55 and the heat-conducting partition plate 2, and a spoiler air outlet 52 is arranged at the upper part of the second air duct 512. Thus, a spoiler air duct 51 with bottom air return and upper air outlet is formed. The cold quantity received by the heat-conducting partition plate 2 is guided to the storage compartment 12 through the spoiler air duct 51, thereby improving the refrigeration efficiency of the storage compartment 12.

[0084] Among them, the spoiler plate is fixed relative to the heat-conducting partition plate 2.

[0085] Furthermore, the heat-conducting partition plate 2 is provided with a dehumidification port 26 communicating the cooling chamber 35 and the storage compartment 12. A dehumidification air door 27 for opening or closing the dehumidification port 26 is arranged at the dehumidification port 26.

[0086] Combined Figure 5 、 Figure 6 As shown in

[0087] The inner container 11 defines a storage compartment 12 and a cooling chamber 35, and a partition wall is arranged in the inner container 11 between the storage compartment 12 and the cooling chamber 35.

[0088] The partition wall is provided with a dehumidification port 26 communicating the storage compartment 12 and the cooling chamber 35, and a dehumidification air door 27 for opening or closing the dehumidification port 26 is arranged at the dehumidification port 26. The dehumidification component includes the dehumidification port 26 and the dehumidification air door 27. When dehumidification is not required, there is no air flow exchange between the storage compartment 12 and the cooling chamber 35, so as to reduce the temperature and humidity fluctuations in the storage compartment 12. Fixed-point humidity control can be realized to ensure that the humidity fluctuation in the storage compartment 12 is ±2%.

[0089] Specifically, after the dehumidification air door 27 is opened, the storage compartment 12 and the cooling chamber 35 are communicated. Due to the large temperature difference between the cooling chamber 35 and the storage compartment 12, there is a pressure difference. When the dehumidification air door 27 is opened, under the action of the pressure difference, the air in the storage compartment 12 and the refrigeration cavity forms natural convection, and the cold air in the cooling chamber 35 is used to dehumidify the storage compartment 12. Compared with multiple air doors and air outlets, a single air outlet can better control the air exchange rate and frequency between the two chambers, further reducing the temperature and humidity fluctuations while ensuring the reliability of the dehumidification air door 27.

[0090] The refrigeration device further includes a humidification component 6 respectively arranged in the inner container 11 and adjacent to the storage compartment 12.

[0091] Further, the humidifying component 6 includes a water storage box 61 having a water storage cavity 611, a humidifying air duct 62 communicating the water storage cavity 611 with the storage chamber 12, and a humidifying fan 63 located in the humidifying air duct 62. The humidifying fan 63 is configured to blow the humidified air in the water storage cavity 611 into the storage chamber 12. The humidifying fan 63 is disposed in the humidifying air duct 62 so that air circulates between the water storage cavity 611 and the storage chamber 12, thereby humidifying the storage chamber 12 through the humidified air.

[0092] Further, the humidifying component 6 is disposed at the bottom of the inner container 11. The humidifying component 6 further includes a housing 64 disposed on the top of the water storage box 61, a humidifying air inlet 65 and a humidifying air outlet 66 respectively formed on the housing 64. Among them, the storage chamber 12 is formed on the upper side of the housing 64. The housing 64 is disposed between the water storage box 61 and the storage chamber 12.

[0093] The humidifying air inlet 65 and the humidifying air outlet 66 are disposed at both ends of the humidifying air duct 62 and communicate with the water storage cavity 611 and the storage chamber 12 respectively. The humidifying air inlet 65 communicates the water storage cavity 611 with the storage chamber 12, and the humidifying air outlet 66 communicates the water storage cavity 611 with the storage chamber 12.

[0094] Further, the housing 64 includes a housing body 641 and a cover body 642 covering the top of the housing body 641, and the storage chamber 12 is formed on the upper side of the cover body 642.

[0095] The humidifying air inlet 65 includes a through air inlet hole 651 formed by the housing body 641, an air inlet channel 652 formed by the housing body 641 and communicating with the through air inlet hole 651, and an air inlet opening 653 formed by the cover body 642 and communicating the storage chamber 12 with the air inlet channel 652. The air inlet opening 653 is arranged facing the storage chamber 12. The through air inlet hole 651 penetrates the housing body 641 in the up and down direction to communicate the water storage cavity 611 with the air inlet channel 652. The air inlet channel 652 communicates the through air inlet hole 651 with the air inlet opening 653. The air in the storage chamber 12 sequentially passes through the air inlet opening 653, the air inlet channel 652, the humidifying fan 63, the through air inlet hole 651, and the water storage cavity 611 under the promotion of the humidifying fan 63, fully contacts with the water storage cavity 611 to become wet air, and then enters the storage chamber 12 through the humidifying air outlet 66 to humidify the storage chamber 12, so as to complete the humidifying process.

[0096] Among them, the humidifying fan 63 is disposed at the air inlet channel 652.

[0097] Further, the first air duct 511 of the turbulent flow air duct 51 and the turbulent flow air return opening 53 are formed on the housing 64. The humidifying air inlet 65 and the humidifying air outlet 66 are disposed on opposite sides of the first air duct 511, so as to improve the integration degree of the overall structure of the refrigeration device, and has the advantages of compact structure and strong integrity.

[0098] Furthermore, the humidification component 6 also includes a water-absorbing sponge, a sterilization module and a water level sensor respectively arranged in the water storage chamber 611. Preferably, the water-absorbing sponge is configured as a wavy water-absorbing and antibacterial sponge.

[0099] Furthermore, 2 / 3 of the height of the water-absorbing sponge is placed in water, and 1 / 3 of the height of the water-absorbing sponge is placed in the air above the water surface, which serves to increase the contact area between water and air. Under the action of the humidifying fan 63, the storage compartment can be quickly humidified.

[0100] Further, the humidification component 6 also includes baffles 68 rotatably arranged at the humidification air inlet 65 and the humidification air outlet 66. The humidification component 6 also includes a rotating shaft arranged in cooperation with the baffle 68, and the baffle 68 rotates around the rotating shaft. Preferably, the baffle 68 is set as a lightweight baffle 68 with a relatively light mass.

[0101] When the humidifying fan 63 is started, the baffle 68 rotates to open the humidifying air inlet 65 and the humidifying air outlet 66. Specifically, when the humidifying fan 63 is started, the baffle 68 rotates around the rotation axis under the action of wind force, so that the humidifying air inlet 65 and the humidifying air outlet 66 are opened to a certain extent, and the humidifying air duct 62 is connected so that the water storage chamber 611 is connected to the storage compartment 12.

[0102] When the humidification fan 63 is turned off, the baffle 68 rotates to close the humidification air inlet 65 and the humidification air outlet 66. Specifically, in the non-humidification state, the baffle 68 cooperates closely with the humidification air inlet 65 and the humidification air outlet under the action of gravity, switches the connection between the water storage chamber 611 and the storage compartment 12, and prevents the humidification component 6 from affecting the humidity of the storage compartment 12.

[0103] Combination Figure 7 , Figure 8 As shown, further, the internal air path of the water storage box 61 can be designed as a "I" shape, a "U" shape, an "M" shape or other internal air paths. The "I"-shaped internal air path means that there is no partition plate between the water storage boxes 61 to separate the humidification air inlet space and the humidification air outlet space.

[0104] Furthermore, the internal air path of the "U"-shaped water storage box 61 is specifically that the humidification component 6 also includes a partition plate 69 with one end connected to the inner wall of the water storage box 61, and the humidification air inlet 65 and the humidification air outlet 66 are respectively arranged on opposite sides of the partition plate 69.

[0105] The humidification air duct 62 includes an air inlet path extending from the humidification air inlet 65 to the other end of the partition plate 69, and an air outlet path extending from the air inlet path to the humidification air outlet 66. This prolongs the passage path of air in the water storage chamber 611, making the air contact with water longer, thereby improving the humidification amount and humidification efficiency.

[0106] Further, the humidifying component 6 further includes a plurality of partition plates 69 respectively connected to the inner wall of the water storage box 61. The plurality of partition plates 69 are disposed between the humidifying air inlet 65 and the humidifying air outlet 66.

[0107] Wherein, one of the adjacent two partition plates 69 is connected to one inner wall side of the water storage box 61, and the other is connected to the other inner wall side of the water storage box 61. The humidifying air duct 62 extends from the humidifying air inlet 65 along the partition plate 69 to the humidifying air outlet 66. Further extending the passing path of the air in the water storage cavity 611, so that the air contacts with water for a longer time, improving the humidifying amount and the humidifying efficiency.

[0108] Further, the refrigeration device further includes a plate evaporator 3 disposed in the inner tank 11, and the partition wall is a heat conduction partition plate 2 on the side of the rear wall of the plate evaporator 3 facing away from the inner tank 11. The description of the heat conduction partition plate 2 has been detailed in the foregoing, and will not be elaborated herein.

[0109] The plate evaporator 3 divides the space between the heat conduction partition plate 2 and the rear wall of the inner tank 11 into a cooling chamber 35 and a cold air circulation chamber 25. The heat conduction partition plate 2 is at least partially exposed in the storage room 12, and a fan 4 is disposed in the cooling chamber 35 or the cold air circulation chamber 25; wherein, the dehumidifying port 26 is disposed on the part of the heat conduction partition plate 2 exposed in the storage room 12.

[0110] Wherein, the cold quantity of the plate evaporator 3 is radiated into the storage room 12 through the heat conduction partition plate 2.

[0111] Further, an air return port 33 flowing from the cold air circulation chamber 25 to the cooling chamber 35 is formed above the evaporation plate 31, and an air inlet 34 flowing from the cooling chamber 35 to the cold air circulation chamber 25 is formed below the evaporation plate 31. The fan 4 is disposed at the position of the air inlet 34. The description of the circulation path between the cooling chamber 35 and the cold air circulation chamber 25 has been detailed in the foregoing, and will not be elaborated herein.

[0112] Further, the dehumidifying port 26 is disposed opposite to the air return port 33. The cold air in the cooling chamber 35 enters the cold air circulation chamber 25 from the air inlet 34 and flows upward, and then enters the cooling chamber 35 through the air return port 33 and flows downward to the air inlet 34. Thus, the cold air circulation between the cold air circulation chamber 25 and the cooling chamber 35 is completed. The dehumidifying port 26 adds the cold air in the cooling chamber 35, thereby improving the convection between the air in the storage room 12 and the refrigeration cavity, and dehumidifying the storage room 12 by using the cold air in the cooling chamber 35, improving the dehumidifying efficiency. The dehumidifying port 26 is a grid-shaped opening structure. The size of the dehumidifying port 26 is smaller than the size of the air return port 33.

[0113] To solve the above problems, the present invention also provides a control method.

[0114] A control method for a refrigeration device as described above, including,

[0115] Obtain the actual humidity RH in the storage room 12 respectively 实际 and the set humidity RH 设定 , and adjust the opening degree of the dehumidification air door 27 for opening and closing the dehumidification port 26 according to the difference between RH 实际 and RH 设定 .

[0116] Specifically, the difference between RH 实际 and RH 设定 reflects whether the storage room 12 needs dehumidification.

[0117] In the case of no need for dehumidification, there is no air flow exchange between the storage room 12 and the cooling room 35 to reduce the temperature and humidity fluctuations in the storage room 12. After the dehumidification air door 27 is opened, the storage room 12 and the cooling room 35 are connected. Due to the large temperature difference between the cooling room 35 and the storage room 12, there is a pressure difference. When the dehumidification air door 27 is opened, under the action of the pressure difference, the air in the storage room 12 and the refrigeration cavity forms natural convection, and the cold air in the cooling room 35 is used to dehumidify the storage room 12. Compared with multiple air doors and air vents, a single air vent can better control the air exchange rate and frequency between the two rooms, further reducing the temperature and humidity fluctuations while ensuring the reliability of the dehumidification air door 27.

[0118] Furthermore

[0119] After obtaining the actual humidity RH 实际 and the set humidity RH 设定 , calculate the difference RH 实际 between RH 设定 and RH 实际 , that is, RH 设定 -RH 实际 , and judge whether RH 设定 -RH 实际 -RH 设定 > 0;

[0120] When RH 实际 -RH 设定 > 0, set the dehumidification air door 27 to open the dehumidification port 26;

[0121] When RH 实际 -RH 设定 ≤ 0, set the dehumidification air door 27 to close the dehumidification port 26.

[0122] Specifically, RH 实际 -RH 设定 > 0 indicates that the humidity in the storage room 12 is high, and the dehumidification port 26 is opened through the dehumidification air door 27 to dehumidify the inside of the storage room 12.

[0123] RH 实际 -RH设定 < 0 indicates that the storage room 12 does not require dehumidification.

[0124] Further,

[0125] When RH 实际 - RH 设定 > 0, it is judged whether RH 实际 - RH 设定 satisfies RH 实际 - RH 设定 > RH 预设1 ;

[0126] When RH 实际 - RH 设定 satisfies RH 实际 - RH 设定 > RH 预设1 , the dehumidification damper 27 is set to fully open the dehumidification port 26;

[0127] When RH 实际 - RH 设定 satisfies RH 实际 - RH 设定 ≤ RH 预设1 , it is judged whether RH 实际 - RH 设定 satisfies RH 实际 - RH 设定 > RH 预设2 , where 0 < RH 预设2 < RH 预设1 ;

[0128] When RH 实际 - RH 设定 satisfies RH 预设2 < RH 实际 - RH 设定 ≤ RH 预设1 , the dehumidification damper 27 is set to open 2 / 3 of the dehumidification port 26;

[0129] When RH 实际 - RH 设定 satisfies 0 < RH 实际 - RH 设定 ≤ RH 预设2 , the dehumidification damper 27 is set to open 1 / 3 of the dehumidification port 26.

[0130] Specifically, the opening degree of the dehumidification damper 27 is related to the actual humidity RH 实际 , the set humidity RH 设定 . The greater the difference between RH 实际 - RH 设定 , the greater the opening degree of the dehumidification damper 27 and the greater the opening of the dehumidification port 26, thereby improving the dehumidification amount and the dehumidification efficiency.

[0131] Preferably, the aforementioned RH 预设1 is 10%. The aforementioned RH 预设2 is 5%.

[0132] Specifically, when the actual humidity RH 实际 is more than 10% greater than the set humidity RH 设定 the damper is fully open; when the actual humidity RH 实际 is between 5 - 10% greater than the set humidity RH 设定 the dehumidification damper 27 is opened 2 / 3; when the actual humidity RH 实际 is between 0 - 5% greater than the set humidity RH 设定 the dehumidification damper 27 is opened 1 / 3; in other states, the dehumidification damper 27 is closed, which has the advantage of finely adjusting the opening degree of the dehumidification damper 27.

[0133] Compared with the prior art, for the refrigeration equipment and control method provided by the present invention, a dehumidification port 26 communicating the storage room 12 and the cooling chamber 35 is provided on the partition wall between the storage room 12 and the cooling chamber 35, and a dehumidification damper 27 for opening or closing the dehumidification port 26 is provided at the dehumidification port 26. When dehumidification is not required, there is no air flow exchange between the storage room 12 and the cooling chamber 35 to reduce the temperature and humidity fluctuations in the storage room 12. When dehumidification is required, the dehumidification damper 27 is opened to connect the storage room 12 and the cooling chamber 35, and natural convection is formed in the air in the storage room and the refrigeration cavity. The cold air in the cooling chamber 35 is used to dehumidify the storage room 12. Compared with multiple damper air inlets, a single air inlet can better control the air exchange rate and frequency between the two chambers, further reducing the temperature and humidity fluctuations while ensuring the reliability of the dehumidification damper 27. And through a water storage box 61 having a water storage cavity 611, a humidification air duct 62 connecting the water storage cavity 611 and the storage room 12, and a humidification fan 63 located in the humidification air duct 62, the humidification fan 63 is arranged in the humidification air duct 62 so that air circulates between the water storage cavity 611 and the storage room 12, thereby humidifying the storage room 12 with humidified air. Through the combined action of humidification and dehumidification, the humidity requirement of the storage room 12 can be met as soon as possible, enhancing the convenience of humidity regulation, and having the advantages of diverse humidity regulation, easy regulation, compact structure, and high space utilization rate.

[0134] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
