Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a humidity control method for refrigeration equipment. Background Technology

[0002] Some existing refrigeration equipment, such as wine cabinets and cigar cabinets, has specific requirements for the temperature and humidity range inside the cabinet to ensure that the stored items are kept under relatively constant temperature and humidity conditions to achieve optimal performance. To address this, some refrigeration equipment uses a partition between the refrigeration chamber where the stored items are stored and the evaporator chamber where the evaporator exchanges heat, in order to avoid the evaporator affecting the humidity inside the refrigeration chamber. The partition transfers cooling capacity, and dehumidification vents are provided on the partitions for dehumidification by the evaporator when the humidity in the refrigeration chamber is too high. However, since there is a humidity difference between the isolated refrigeration chamber and the evaporator chamber, the humidity inside the refrigeration chamber will fluctuate significantly in a short period of time after the dehumidification vents are opened, which is detrimental to the storage of the items. Summary of the Invention

[0003] The purpose of this application is to provide a humidity control method for refrigeration equipment. When the humidity inside the refrigeration equipment is higher than the humidity when the dehumidification damper is open, the humidity inside the refrigeration room is compared with the humidity inside the cooling room to determine the timing of opening the dehumidification damper. This avoids the temporary impact of opening the dehumidification damper on the humidity inside the refrigeration room and solves the problem of the impact of opening the dehumidification damper on the humidity inside the refrigeration room in the prior art.

[0004] In order to achieve one of the above-mentioned objectives, one embodiment of this application provides a method for controlling humidity in a refrigeration device. The refrigeration device includes a refrigeration chamber, a cooling chamber located behind the refrigeration chamber, a heat-conducting partition separating the refrigeration chamber and the cooling chamber, and a plate evaporator disposed in the cooling chamber. The heat-conducting partition is provided with a dehumidification port and a dehumidification damper.

[0006] Obtain the humidity (RH) inside the cooling room 制冷 and the humidity (RH) in the cooling room 供冷 and RH 制冷 With the dehumidification damper, the opening humidity (RH) 风门ON Compare;

[0007] If RH 制冷 ≥RH 风门ON Then compare RH 制冷 and RH 供冷 ;

[0008] If RH 制冷 >RH 供冷 If the RH is positive, the dehumidification damper will open; otherwise, the compressor will start until the RH is restored. 供冷 <RH风门ON Then open the dehumidifier damper; after opening the dehumidifier damper, wait for the RH to rise. 制冷 ≤ Humidity (RH) of the dehumidifying damper when closed 风门OFF Then the dehumidification damper will be closed.

[0009] As a further improvement of one embodiment of this application, it also includes a humidification component disposed in the cooling room, the humidification component including a water box and a humidification fan;

[0010] If RH 制冷 ≤ Humidification level (RH) when the humidifier is turned on 风机ON Then control the humidifier fan to turn on; if RH 制冷 ≥ Humidity (RH) when the humidifier is turned off 风机OFF If the humidifier fan is turned off, then the humidifier fan will be shut down.

[0011] As a further improvement of one embodiment of this application, the humidity control method further includes a low-temperature compensation mode, and the refrigeration equipment further includes a heating wire disposed in the cooling room. The humidity control method further includes:

[0012] Obtain ambient temperature T 环 Temperature T in the refrigeration room 制冷 Preset temperature T 预 and T 预 The corresponding compressor shutdown point T 关 ;

[0013] If T 环 <T 预 And T 制冷 ≤T 关 If the temperature is low, the refrigeration equipment will be controlled to enter the low-temperature compensation mode. Once in the low-temperature compensation mode, the heating wire will be energized to start heating.

[0014] As a further improvement of one embodiment of this application, the refrigeration equipment also includes an evaporator fan disposed in the cooling room and a turbulence fan disposed in the refrigeration room. After the heating wire is turned on, the evaporator fan and the turbulence fan are controlled to turn on.

[0016] Obtain the temperature T inside the cooling room 制冷 and T 预 The corresponding compressor start-up point T 开 and T 制冷 and T 开 Compare;

[0017] If T 制冷 ≥T 开If the heating element is de-energized and stops heating, the compressor will start. After the compressor starts for the first preset time t1, the dehumidifying damper and humidifying fan will open or close according to the cooling mode.

[0018] As a further improvement of one embodiment of this application, after a second preset time t2 when the compressor is turned on, the compressor is controlled to shut down, where t2 > t1.

[0019] As a further improvement to one embodiment of this application, after the compressor is turned off, T is obtained again. 制冷 and T 制冷 With T 关 Comparison, if T 制冷 ≤T 关 Then, the heating wire is energized again to start heating.

[0020] As a further improvement to one embodiment of this application, when T 制冷 >T 开 When the duration is greater than or equal to the third preset time t3, the low temperature compensation mode will be exited and the cooling mode will be entered.

[0021] As a further improvement to one embodiment of this application, if information indicating a continuous opening of the dehumidification damper is received, then when RH 制冷 -RH 风门ON When the concentration is ≥10%, the compressor will be turned on.

[0022] As a further improvement of one embodiment of this application, when the dehumidifying damper malfunctions and remains open, the closing of the dehumidifying damper and the opening and closing of the humidifying fan remain unchanged.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] The terms used in this document, such as “center,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” indicating spatial relative positions, are used for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative positions” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0039] For example, if the device in the figure is flipped, a unit described as being "below" or "under" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise) and the spatially related descriptive terms used herein will be interpreted accordingly.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] Furthermore, it should be understood that although the terms "first," "second," etc., may be used herein to describe various elements or structures, the objects being described should not be limited by these terms. These terms are only used to distinguish these objects from one another. For example, a first air duct may be referred to as a second air duct, and similarly, a second air duct may be referred to as a first air duct, without departing from the scope of protection of this application.

[0042] This application provides a humidity control method for a refrigeration device, such as... Figures 1-10 As shown, the refrigeration equipment includes a refrigeration chamber 101, a cooling chamber located behind the refrigeration chamber 101, a heat-conducting partition 5 separating the refrigeration chamber 101 and the cooling chamber, and a plate evaporator 4 installed in the cooling chamber. The heat-conducting partition 5 is provided with a dehumidification port 51 and a dehumidification damper 52.

[0043] Humidity control methods include cooling mode, which includes the following steps:

[0044] Obtain the humidity (RH) inside the cooling room 101 制冷 and the humidity (RH) in the cooling room 供冷 and RH 制冷 The opening humidity RH of the dehumidifying damper 52 风门ON Compare;

[0045] If RH 制冷 ≥RH 风门ON Then compare RH 制冷 and RH 供冷 ;

[0046] If RH 制冷 >RH 供冷 If the dehumidification damper 52 is activated, the compressor will open; otherwise, the compressor will start until the RH level is reached. 供冷 <RH 风门ON Then open the dehumidification damper 52; after opening the dehumidification damper 52, wait for the RH 制冷 ≤Dehumidification damper 52 closing humidity RH 风门OFF Then the dehumidification damper 52 will be closed.

[0047] like Figure 8 In this configuration, the plate evaporator 4 divides the cooling room into an interconnected cooling chamber 102 and a cold air circulation chamber 103. The cold air circulation chamber 103 is located between the heat-conducting baffle 5 and the plate evaporator 4, while the cooling chamber 102 is located on the side of the plate evaporator 4 facing away from the cold air circulation chamber 103. The cooling energy generated by the plate evaporator 4, promoted by the evaporation fan 6 in the cooling room, enters the cold air circulation chamber 103 in the form of cold air and is transferred to the heat-conducting baffle 5. The heat-conducting baffle 5 radiates the cooling energy to the air in the cooling room 101 to complete the cooling of the cooling room 101. After exchanging heat with the heat-conducting baffle 5, the cold air becomes hot air and then enters the cooling chamber 102 to exchange heat with the plate evaporator 4 to become cold air, thus completing the refrigeration cycle.

[0048] The refrigeration equipment in this application separates the refrigeration chamber 101 for storing items from the cooling chamber equipped with an evaporator through a heat-conducting partition 5. Since the dry cold air from the cooling chamber does not enter the refrigeration chamber 101, and the refrigeration chamber 101 is no longer cooled by forced circulation of low-temperature cold air, the moisture in the refrigeration chamber 101 will not be carried away, which is beneficial to controlling the humidity in the refrigeration chamber 101. It has the advantages of high refrigeration efficiency, controllable humidity, high space utilization, and compact structure.

[0049] like Figure 8 , 9 In this design, a dehumidification port 51, located on the heat-conducting partition 5, connects the cooling chamber 102 and the refrigeration chamber 101. The dehumidification damper 52 opens or closes the dehumidification port 51, ensuring no airflow exchange between the refrigeration chamber 101 and the cooling chamber 102 when dehumidification is not required, thus reducing humidity fluctuations within the refrigeration chamber 101. This allows for targeted humidity control, maintaining humidity fluctuations in the refrigeration chamber 101 within ±2%. The dehumidification port 51 is located at the top of the heat-conducting partition 5, although it can also be located at other positions on the heat-conducting partition 5.

[0050] When the humidity RH in the cooling room 101制冷 The opening humidity (RH) is higher than 52 RH of the dehumidifying damper. 风门ON First, determine the humidity (RH) inside the cooling room 101. 制冷 and the humidity (RH) in the cooling room 供冷 The size, if the humidity RH in the cooling room 101 制冷 If the humidity is too high, the dehumidification damper 52 can be opened directly. After the dehumidification damper 52 is opened, the cooling room 101 and the cooling supply room are connected. Because the temperature difference between the cooling supply room and the cooling room 101 is large, there is a pressure difference. When the dehumidification damper 52 is opened, the air in the cooling room 101 and the cooling supply room forms a natural convection under the action of the pressure difference, and the cold air in the cooling supply room is used to dehumidify the cooling room 101.

[0051] If the humidity RH in the cooling room 供冷 The humidity is too high, because the RH in the cooling room 101 is too high at this time. 制冷 The humidity level (RH) at which the dehumidifier damper is open is already greater than 52. 风门ON That is, the humidity RH in the cooling room 101 制冷 The humidity level is already too high. To prevent water vapor from entering the cooling room 101 and increasing the humidity (RH) inside the cooling room 101, further measures should be taken. 制冷 First, turn on the compressor to raise the RH level in the cooling room. 供冷 Lower the humidity, then open the dehumidification damper 52 to dehumidify the refrigeration room 101.

[0052] When the humidity RH of the cooling room 101 制冷 ≤Dehumidification damper 52 closing humidity RH 风门OFF At that time, it indicates the RH of the refrigeration room 101. 制冷 The requirements are met; closing the dehumidifying damper 52 will prevent the humidity (RH) level in the refrigerated room 101 from rising. 制冷 Continue to decrease.

[0053] In some embodiments, the refrigeration equipment in this application further includes a humidification component disposed in the refrigeration chamber 101, the humidification component including a water box and a humidification fan 23;

[0054] If RH 制冷 ≤ Humidifier fan 23 RH 风机ON Then control the humidifier fan 23 to turn on. If RH 制冷 ≥Humidifier fan 23 Humidity (RH) when turned off 风机OFF If the humidifier fan 23 is turned off, then the humidifier fan 23 will be shut off.

[0055] A humidification unit is installed in the cooling chamber 101 to maintain the humidity (RH) within the cooling chamber 101. 制冷 When the humidity is too low, the humidifier fan 23 can be turned on to humidify. When the humidity RH in the cooling room 101... 制冷≤ Humidifier fan 23 RH 风机ON When, it indicates the humidity (RH) inside the cooling room 101 at this time. 制冷 The humidity is too low and needs to be increased. Furthermore, the RH level in cooling room 101... 制冷 ≥Humidifier fan 23 Humidity (RH) when turned off 风机OFF This indicates that the humidity (RH) inside the cooling room 101 is... 制冷 The humidification level has been raised to the required standard and no further humidification is needed, even if the fan is turned off.

[0056] In some embodiments, the humidity control method further includes a low-temperature compensation mode, and the refrigeration equipment further includes a heating wire disposed in the cooling room. The humidity control method further includes:

[0057] Obtain ambient temperature T 环 The temperature T inside the refrigeration room 101 制冷 Preset temperature T 预 and T 预 The corresponding compressor shutdown point T 关 ;

[0058] If T 环 <T 预 And T 制冷 ≤T 关 If the temperature is low, the refrigeration equipment will be controlled to enter the low-temperature compensation mode. Once in the low-temperature compensation mode, the heating wire will be energized to start heating.

[0059] When the refrigeration equipment is at an ambient temperature T 环 Below the preset temperature T 预 In an environment where the temperature T inside the cooling room 101 is... 制冷 It may be affected by the ambient temperature T 环 The effect is that the temperature is lower than or equal to the preset temperature T. 预 Corresponding compressor shutdown point T 关 At this time, the temperature T inside the cooling room 101 is 制冷 The temperature is too low and needs to be compensated by heating with heating wires to raise the temperature T inside the cooling chamber 101. 制冷 Temperature rises.

[0060] In some embodiments, the refrigeration equipment further includes an evaporator fan 6 disposed in the cooling room and a turbulence fan 73 disposed in the refrigeration chamber 101. After the heating wire is turned on, the evaporator fan 6 and the turbulence fan 73 are activated. When the heating wire is turned on, the evaporator fan 6 in the cooling room circulates the heat generated by the heating wire within the cooling room, and simultaneously transfers the heat to the refrigeration chamber 101 through the heat-conducting baffle 5. The turbulence fan 73 in the refrigeration chamber 101 circulates the heat on the heat-conducting baffle 5 within the refrigeration chamber 101, thereby increasing the temperature T within the refrigeration chamber 101. 制冷 A uniform increase.

[0061] In some embodiments, the low-temperature compensation mode further includes:

[0062] Obtain the temperature T inside the cooling room 101 制冷 and T 预 The corresponding compressor start-up point T 开 and T 制冷 and T 开 Compare;

[0063] If T 制冷 ≥T 开 If the heating element is de-energized and stops heating, the compressor will start. After the compressor starts for the first preset time t1, the dehumidifying damper 52 and the humidifying fan 23 will open or close according to the cooling mode.

[0064] After entering the low-temperature compensation mode, the heating wire heats up the temperature T inside the refrigeration chamber 101. 制冷 To prevent the temperature T inside the refrigeration room 101 from rising, 制冷 Temperatures higher than the allowable temperature (i.e., the preset temperature T) 预 The corresponding compressor start-up point T 开 Therefore, the temperature T inside the cooling room 101 needs to be adjusted. 制冷 With T 预 The corresponding compressor start-up point T 开 For comparison, when the temperature T inside the cooling room 101... 制冷 Reaching or even exceeding T 预 The corresponding compressor start-up point T 开 At that time, it was proven that the temperature T inside the cooling room 101 was... 制冷 The temperature is too high. The heating element needs to be stopped, and the compressor needs to be turned on to start cooling.

[0065] After the compressor has been running for a certain period of time, the temperature T inside the refrigeration chamber 101 will rise. 制冷 Fluctuations will cause the humidity (RH) in the cooling room 101 to fluctuate. 制冷 Humidity fluctuations also occur, requiring humidity control. Humidity control refers to the logic control of the dehumidifying damper 52 and the humidifying fan 23 in cooling mode to open or close or stop them.

[0066] In some embodiments, the first preset time t1 is 2 minutes.

[0067] In some embodiments, after a second preset time t2 during compressor startup, the compressor is controlled to shut down, where t2 > t1. At this time, the compressor is only started to reduce the temperature rise caused by the heating element; therefore, the compressor cannot be started and stopped as in cooling mode, but needs to be turned off after a certain period of time to prevent the temperature T inside the cooling chamber 101 from rising. 制冷 Too low.

[0068] In some embodiments, the second preset time t2 is 10 minutes.

[0069] In some embodiments, after the compressor is turned off, T is obtained again. 制冷 and T 制冷 With T 关 Comparison, if T 制冷 ≤T 关 Then, the heating element is energized again to start heating. After the compressor is turned off, the refrigeration equipment stops cooling, but because the ambient temperature T is still high... 环 Too low, below the preset temperature T 预 The temperature T inside the refrigeration room 101 制冷 It will still be affected by the ambient temperature T 环 The temperature T inside the refrigeration room 101 is reduced due to the influence of the temperature. 制冷 Reduce again to the compressor shutdown point T 关 When the temperature is above or below, it is necessary to control the heating wire to power on again to raise the temperature of the cooling chamber 101.

[0070] In some embodiments, when T 制冷 >T 开 And when the duration is ≥ the third preset time t3, exit the low temperature compensation mode and enter the cooling mode. When the temperature T in the cooling chamber 101 is... 制冷 Able to continuously exceed the compressor start-up point T 开 This proves that the ambient temperature T at this time is... 环 The temperature has risen, and the refrigeration equipment is no longer in a low-temperature environment. It can exit the low-temperature compensation mode and enter the refrigeration mode.

[0071] In some embodiments, the third preset time t3 is 2h.

[0072] In some embodiments, if information indicating a persistent open fault is received regarding the dehumidification damper 52, then when RH 制冷 -RH 风门ON When the concentration is ≥10%, the compressor will be turned on.

[0073] If the dehumidification damper 52 malfunctions and cannot close, remaining open, then the refrigeration equipment is essentially no different from a traditional air-cooled refrigerator. Compared to when the dehumidification damper 52 is working normally, when the dehumidification damper 52 is constantly open, the compressor's cooling process affects the humidity (RH) inside the refrigeration compartment 101. 制冷 The impact is significant, leading to a substantial decrease in humidity. Therefore, for humidity control, the humidity RH in the cooling room 101 is crucial. 制冷 The opening humidity (RH) is higher than 52 RH of the dehumidifying damper. 风门ON Only when the humidity reaches 10% above the limit will the compressor be turned on, reserving a certain range of humidity for the compressor to dehumidify.

[0074] In some embodiments, when the dehumidifying damper 52 remains open due to a malfunction, the closing of the dehumidifying damper 52 and the opening and closing of the humidifying fan 23 remain unchanged.

[0075] Regarding the refrigeration equipment in this invention, the humidification component is disposed at the bottom of the refrigeration chamber 101, such as... Figure 6 In the humidification assembly, the water box 1 has an upward-opening water storage cavity 11. The humidification assembly also includes a volute plate 2 covering the opening of the water box 1, a humidification cover plate 3 connected to the volute plate 2, and a humidification fan 23. The volute plate 2 has an upward-opening return air cavity 21 and an air outlet 22. The humidification cover plate 3 has a humidification air outlet 31 and a humidification return air outlet 32. The humidification air outlet 31 communicates with the air outlet 22, and the humidification cover plate 3 covers the upward-opening return air cavity 21. The return air cavity 21 includes: a first return air cavity 211 communicating with the cooling chamber 101 through the humidification return air outlet 32, a second return air cavity 212 communicating with the water storage cavity 11, and a third return air cavity 213 equipped with the humidification fan 23. The third return air cavity 213 communicates with the first return air cavity 211 and the second return air cavity 212.

[0076] When the cooling room 101 needs humidification, the humidifying fan 23 is turned on. Under the action of the humidifying fan 23, the air in the cooling room 101 is drawn into the first return air chamber 211, passes through the third return air chamber 213 and the second return air chamber 212 in sequence, and enters the water storage chamber 11. The water in the water storage chamber 11 humidifies the flowing air, and finally the humidified air is blown out from the humidifying air outlet 31 through the air outlet 22. Preferably, a wet film or other material can be installed in the water storage chamber 11 to enhance the humidification effect.

[0077] In some embodiments, a humidifying damper 24 is provided between the second return air chamber 212 and the third return air chamber 213. When the humidifying fan 23 is turned off, the humidifying damper 24 disconnects the connection between the second return air chamber 212 and the third return air chamber 213, preventing the air in the refrigeration chamber 101 and the water storage chamber 11 from circulating, so that the humidity in the refrigeration chamber 101 increases when humidification is not required. When the humidifying fan 23 is turned on, the air force blows the humidifying damper 24 open, connecting the second return air chamber 212 and the third return air chamber 213, and the air in the refrigeration chamber 101 and the water storage chamber 11 circulates to humidify the refrigeration chamber 101.

[0078] In some embodiments, the refrigeration equipment further includes a turbulence duct 7 at least partially adjacent to the heat-conducting partition 5, a turbulence fan 73 disposed within the turbulence duct 7, a turbulence outlet 721, and a turbulence return air outlet 33; wherein the turbulence outlet 721 and the turbulence return air outlet 33 connect the turbulence duct 7 and the refrigeration chamber 101. Under the action of the turbulence fan 73, air circulates between the turbulence duct 7 and the refrigeration chamber 101, which helps to ensure the uniformity of temperature within the refrigeration chamber 101.

[0079] In some embodiments, the turbulence duct 7 includes a first duct 71 disposed at the bottom of the cooling room 101 and used to accommodate the turbulence fan 73, and a second duct 72 extending upward from the first duct 71 and disposed adjacent to the heat-conducting baffle 5. The first duct 71 and the second duct 72 are interconnected. The turbulence outlet 721 is connected to the second duct 72, and the turbulence return air outlet 33 is connected to the first duct 71.

[0080] Specifically, the volute plate 2 also forms an upward-opening turbulence cavity, in which a turbulence fan 73 is disposed. A humidifying cover plate 3 is placed over the turbulence cavity, ultimately forming the aforementioned first air duct 71. That is, the turbulence fan 73 is disposed within the first air duct 71, and the humidifying cover plate 3 is also provided with the aforementioned turbulence return air inlet 33. The turbulence return air inlet 33 is disposed at the bottom of the refrigeration chamber 101. Air returns through the turbulence return air inlet 33 at the bottom of the refrigeration chamber 101, forming a turbulence air path with air outlet at the top and return air at the bottom. The hot air entering the turbulence air duct 7 from the turbulence return air inlet 33 at the bottom of the refrigeration chamber 101 fully contacts and exchanges heat with the heat-conducting partition 5 from bottom to top, becoming cold air, and then enters the refrigeration chamber 101 through the turbulence outlet 721. The cold air naturally sinks and then passes through the turbulence return air inlet 33, which has the advantages of reasonable turbulence path setting and high cooling efficiency.

[0081] In some embodiments, the refrigeration equipment further includes a baffle plate 8 disposed on the side of the heat-conducting partition 5 near the refrigeration chamber 101; a second air duct 72 is formed between the baffle plate 8 and the heat-conducting partition 5, and a baffle outlet 721 is disposed at the upper part of the second air duct 72. This forms a baffle air duct 7 with bottom return air and top air outlet. The cooling energy received by the heat-conducting partition 5 is guided into the refrigeration chamber 101 through the baffle air duct 7, thereby improving the refrigeration efficiency of the refrigeration chamber 101.

[0082] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0083] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
