[0042] This invention provides a method for controlling humidity in a refrigeration device. The refrigeration device includes a refrigeration chamber 101 and a humidification component disposed in the refrigeration chamber 101. The humidification component includes a water box 1 and a humidification fan 23.
[0043] like Figure 1 As shown, humidity control methods include:
[0044] Obtain ambient temperature T环 Preset temperature T 设 and preset humidity RH 设 According to the ambient temperature T 环 Preset temperature T 设 and preset humidity RH 设 Confirm the RH (reverse humidity) setting when the humidifier fan 23 is turned on. 风机ON and the humidity (RH) when the machine is off 风机OFF ;
[0045] Obtain the humidity RH of the cooling room 101. If RH ≤ RH 风机ON If RH ≥ RH, then control the humidifier fan 23 to turn on; 风机OFF Then control the humidifier fan 23 to shut down;
[0046] Among them, T 设 The preset temperature and preset humidity (RH) are set for the cooling room 101. 设 The humidity is preset in the refrigeration room 101.
[0047] The refrigeration equipment provided by the present invention is equipped with a humidification component in the refrigeration chamber 101 so that the humidification fan 23 can be turned on to humidify when the humidity in the refrigeration chamber 101 is low.
[0048] The preset temperature T in the refrigeration room 101 设 and the preset humidity RH in the cooling room 101 设 Users typically don't adjust this, but the ambient temperature T 环 It will affect the temperature inside the cooling room 101, but the RH of the humidifier fan 23 when it is turned on will be affected. 风机ON and the humidity (RH) when the machine is off 风机OFF It is also related to the temperature and humidity inside the refrigeration room 101. Therefore, based on the preset temperature T inside the refrigeration room 101... 设 and the preset humidity RH in the cooling room 101 设 And the ambient temperature T, which may change at any time. 环 To confirm the RH of the humidifier fan 23 when it is turned on. 风机ON and the humidity (RH) when the machine is off 风机OFF Then, obtain the humidity RH inside the cooling room 101 and the RH when the humidifier fan 23 is turned on. 风机ON and the humidity (RH) when the machine is off 风机OFF Determine whether to turn the humidifier fan on or off 23.
[0049] In some embodiments, the refrigeration equipment further includes a cooling room located behind the refrigeration room 101, a heat-conducting partition 5 separating the refrigeration room 101 and the cooling room, a plate evaporator 4 and an evaporation fan 6 disposed in the cooling room, the heat-conducting partition 5 being provided with a dehumidification port 51 and a dehumidification damper 52, and the plate evaporator 4 dividing the cooling room into a cooling room 102 and a cold air circulation room 103 that are interconnected.
[0050] Humidity control methods also include those based on T 环 T 设 and RH 设 Confirm the RH of the dehumidifying damper 52 when it is open. 风门ON and humidity (RH) when the door is closed 风门OFF ;
[0051] If RH≥RH 风门ON If RH≤RH 风门OFF Then control the dehumidification damper 52 to close.
[0052] like Figure 6 In this design, 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 as 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 chamber 101, thus completing the cooling of the cooling chamber 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 again, becoming cold air, thereby completing the refrigeration cycle. Since the dry cold air in the cooling chamber 102 does not enter the cooling chamber 101, and the cooling chamber 101 is no longer cooled by forced circulation of low-temperature cold air, the moisture in the cooling chamber 101 is not carried away, which is beneficial for controlling the humidity in the cooling chamber 101. This design has the advantages of high cooling efficiency, controllable humidity, high space utilization, and compact structure.
[0053] 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. When dehumidification is not required, there is no airflow exchange between the refrigeration chamber 101 and the cooling chamber 102, thus reducing humidity fluctuations within the refrigeration chamber 101. This allows for targeted humidity control, ensuring humidity fluctuations in the refrigeration chamber 101 remain within ±2%. Figure 6 , 7 In the middle, the dehumidification port 51 is located at the top of the heat-conducting partition 5. Of course, the dehumidification port 51 can also be located at other positions of the heat-conducting partition 5.
[0054] The humidification unit can humidify when the humidity (RH) of the cooling room 101 is low, while the dehumidification port 51 and dehumidification damper 52 on the heat-conducting partition 5 can dehumidify when the humidity (RH) of the cooling room 101 is high. The dehumidification occurs when the humidity (RH) of the cooling room 101 is greater than or equal to the opening humidity (RH) of the dehumidification damper 52. 风门ON At this time, open the dehumidification damper 52.
[0055] After the dehumidifying damper 52 is opened, the refrigeration chamber 101 and the cooling chamber 102 are connected. Because the temperature difference between the cooling chamber 102 and the refrigeration chamber 101 is large, there is a pressure difference. When the dehumidifying damper 52 is opened, the air in the refrigeration chamber 101 and the cooling chamber 102 forms a natural convection under the action of the pressure difference, and the cold air in the cooling chamber 102 is used to dehumidify the refrigeration chamber.
[0056] When the humidity (RH) of the cooling room 101 is less than the humidity (RH) of the dehumidifying damper 52 when it is closed... 风门OFF When the humidity level of the cooling room 101 is within acceptable limits, closing the dehumidification damper 52 will prevent the humidity level of the cooling room 101 from decreasing further.
[0057] In some embodiments, the refrigeration equipment further includes a heating wire (not shown) disposed in the cooling chamber; after confirming RH 风机ON RH 风机OFF RH 风门ON and RH 风门OFF Beforehand, obtain the cumulative running time of the compressor or the heating wire off time; if the cumulative running time of the compressor is greater than or equal to the first preset time T1 or the heating wire off time is greater than or equal to the second preset time T2, then control the heating wire to be turned on to defrost.
[0058] After continuous cooling, the plate evaporator 4 in the cooling room is prone to frost buildup, requiring defrosting via a heating wire. During the repeated cycles of compressor start-up and shutdown, frost accumulates on the plate evaporator 4 with each compressor start-up. As the compressor's operating time increases, the frost on the plate evaporator 4 gradually accumulates. Therefore, after the compressor has run for a first preset time T1, defrosting of the plate evaporator 4 is necessary. Alternatively, if the heating wire is not turned on for a long time after the previous shutdown, frost will also gradually accumulate on the plate evaporator 4. Therefore, after the heating wire has been off for a second preset time T2, it can be controlled to reopen for defrosting. Preferably, the first preset time T1 is 12 hours, and the second preset time T2 is 96 hours.
[0059] In some embodiments, the RH when the heating wire is turned on 风机ON RH 风机OFF RH 风门ON and RH 风门OFF The value is higher than when the heating wire is not turned on.
[0060] When the heating wire in the cooling room is turned on, heat is transferred to the cooling room 101. Since humidity is calculated as actual moisture content / saturated moisture content, and saturated moisture content is temperature-dependent (higher temperature, higher saturated moisture content), then with the same actual moisture content, a higher temperature will result in a lower humidity value measured in the cooling room 101. Therefore, when the heating wire is turned on, the humidity value is determined based on the ambient temperature T. 环 Preset temperature T 设 and preset humidity RH 设 The confirmed humidification fan 23's operating humidity (RH) 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFF The value is higher than the RH value of the humidifier fan 23 when the heating element is not turned on. 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFF The value is high to eliminate the impact of the heating wire on the humidity (RH) of the cooling room 101 when it is turned on. Preferably, the starting humidity (RH) of the humidifying fan 23 when the heating wire is turned on is high. 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFF The value is 3% higher than when the heating wire is not turned on.
[0061] In some embodiments, with T 环 The increase in RH 风机ON RH 风机OFF RH 风门ON and RH 风门OFF The value of has a decreasing trend.
[0062] Ambient temperature T 环 The higher the temperature, the more the temperature inside the refrigeration room 101 will be compared with the ambient temperature T. 环 The greater the temperature difference, the lower the heat exchange efficiency of the condenser. This necessitates increasing the compressor's operating frequency to maintain the temperature within the cooling chamber 101. However, this increased compressor frequency may cause the cooling capacity to exceed the cooling capacity required by the cooling chamber 101, resulting in a lower temperature within the cooling chamber 101 and consequently, a higher humidity (RH) within the cooling chamber 101. Therefore, as the ambient temperature T... 环 The humidity level (RH) of the humidifier fan 23 when it is turned on increases. 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFFThe value needs to be appropriately reduced.
[0063] In some embodiments, when T is determined 设 Afterwards, with T 环 The increase in RH 风机ON RH 风机OFF RH 风门ON and RH 风门OFF The decrease was 1%.
[0064] The preset temperature T of the refrigeration room 101 设 Once confirmed, set the starting humidity (RH) of humidifier fan 23. 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFF The value of T is related to the ambient temperature. 环 Related, the RH (Return Humidity) setting when the humidifier fan is turned on (23). 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFF A single 1% decrease in the humidity value can prevent the humidity value from dropping too much and causing it to deviate from the preset RH humidity of the cooling room 101. 设 Too large a deviation can also prevent the adjustment value from being too small to eliminate the ambient temperature T. 环 The impact on humidity in cooling room 101.
[0065] In some embodiments, T 环 The interval division includes: T 环 <14℃, 14℃≤T 环 <18℃, 18℃≤T 环 <26℃, 26℃≤T 环 <30℃, T 环 ≥30℃; when T is determined 设 After that, T 环 In the two adjacent intervals mentioned above, the RH in the high-temperature interval 风机ON RH 风机OFF RH 风门ON and RH 风门OFF The value is 1% lower than that in the low-temperature range.
[0066] ambient temperature T 环 Divide the temperature range into zones, based on the ambient temperature T. 环 The aforementioned temperature range affects the starting humidity (RH) of the humidifier fan 23. 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFFThe value can be adjusted and lowered. Alternatively, the ambient temperature T can be adjusted. 环 The temperature range is divided into smaller intervals, and the humidifier fan has an operating humidity (RH) of 23. 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFF The reduction value can also be adjusted to be smaller over a smaller temperature range.
[0067] In some embodiments, with T 设 The increase in RH 风机ON RH 风机OFF RH 风门ON and RH 风门OFF The value shows an increasing trend.
[0068] The preset temperature T of the refrigeration room 101 设 The higher the humidity level, the lower the measured RH value of the refrigeration chamber 101, assuming the moisture content inside the refrigeration chamber 101 remains constant. Therefore, it is necessary to adjust the RH value of the humidifier fan 23 during startup. 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFF The value increases.
[0069] In some embodiments, when T is determined 环 Afterwards, with T 设 The increase in RH 风机ON RH 风机OFF RH 风门ON and RH 风门OFF The increase was 1%.
[0070] Ambient temperature T 环 Once confirmed, set the starting humidity (RH) of humidifier fan 23. 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFF The value is related to the preset temperature T of the cooling room 101. 设 Related, the RH (Return Humidity) setting when the humidifier fan is turned on (23). 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFF The humidity value is increased by 1% at a time, which can prevent the humidity value from rising too much and causing it to deviate from the preset humidity RH of the cooling room 101. 设 If the deviation is too large, it can also prevent the adjustment value from being too small to eliminate the preset temperature T of the refrigeration chamber 101. 设The impact on humidity in cooling room 101.
[0071] In some embodiments, the refrigeration device is a cigar cabinet, T 设 The interval division includes: T 设 ≤16℃, 16℃<T 设 ≤19℃, 19℃<T 设 ≤22℃; when T is determined 环 After that, T 设 In the two adjacent intervals mentioned above, the RH in the high-temperature interval 风机ON RH 风机OFF RH 风门ON and RH 风门OFF The value was 1% higher than in the low-temperature range.
[0072] To ensure the quality of the cigars, the temperature of the refrigeration compartment 101 in the cigar cabinet is usually controlled between 16 and 22°C. The preset temperature T of the refrigeration compartment 101 is set... 设 The temperature range is divided into 16-22℃, based on the preset temperature T of the refrigeration room 101. 设 The aforementioned temperature range affects the starting humidity (RH) of the humidifier fan 23. 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFF The value can be adjusted and increased. Alternatively, the preset temperature T of the cooling room 101 can be set. 设 The temperature range is divided into smaller intervals, and the humidifier fan has an operating humidity (RH) of 23. 风机ON and the humidity (RH) when the machine is off 风机OFF The opening humidity (RH) of the dehumidifying damper 52 风门ON and humidity (RH) when the door is closed 风门OFF The increase can also be adjusted to be smaller over a smaller temperature range.
[0073] Regarding the refrigeration equipment in this invention, the humidification component is disposed at the bottom of the refrigeration chamber 101, such as... Figure 4 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.
[0074] 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.
[0075] 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.
[0076] 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.
[0077] 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.
[0078] 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.
[0079] 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.
