Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a method, device, refrigeration equipment and storage medium for controlling humidification. Background Art

[0002] At present, refrigeration equipment such as freezers usually have a need for humidification to better preserve the items in the refrigeration equipment. In the design of precise humidity control, humidification is required at low humidity, but it may lead to excessive humidification.

[0003] The related technology provides a method for humidification control, which discloses that when the difference between the set humidity RHset and the integrated humidity value RH during the time period from the last shutdown of the aforementioned compressor to the current shutdown is greater than 10%, the direction of the evaporator fan is maintained. If RHN-RH≥5%, that is, within the N compressor working cycles, the humidity increase value in the aging room is not less than 5%, and the aging conditions can be met, then the duty cycle of the evaporator fan remains unchanged; if RHN-RH<5%, that is, within the N compressor working cycles, the humidity increase value in the aging room is less than 5%, and the humidity increase rate is relatively low. Controlling the duty cycle of the evaporator fan to increase can speed up the flow rate of cold air. The faster the speed of the cold air, the more it can promote the evaporation of defrost water in the water tray, thereby making the humidity increase value greater.

[0004] Although the related technology can accelerate humidification, it cannot reduce the problem of excessive humidification.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] Embodiments of the present disclosure provide a method, an apparatus, a refrigeration device, and a storage medium for controlling humidification to reduce the problem of excessive humidification.

[0008] In some embodiments, a method for controlling humidification is provided, comprising:

[0009] Periodically obtain the current humidity of the humidification space;

[0010] When it is determined that humidification is started, a difference ΔRH between the current humidity and the set humidity in the humidification space is determined;

[0011] Determine the duty cycle of the humidification fan according to ΔRH;

[0012] The humidification fan is operated according to the duty cycle to perform humidification.

[0013] By determining the duty cycle of the humidification fan according to the difference ΔRH between the current humidity and the set humidity in the humidification space, and operating the humidification fan for humidification according to the duty cycle, the duty cycle of the humidification fan can be flexibly adjusted according to the difference between the current humidity and the set humidity, thereby effectively reducing the situation of excessive humidification.

[0014] In some embodiments, determining the duty cycle of the humidification fan according to ΔRH comprises:

[0015] In the case of ΔRH ≥ rh1, the duty cycle of the humidification fan is determined to be D1; and / or

[0016] In the case of rh1>ΔRH≥rh2, the duty cycle of the humidification fan is determined to be D2; and / or

[0018] Among them, rh1 is the first humidity range, rh2 is the second humidity range, rh3 is the third humidity range, rh1>rh2>rh3, D1 is the first duty cycle value, D2 is the second duty cycle value, D3 is the third duty cycle value, D1>D2>D3.

[0019] The greater the difference between the current humidity and the set humidity in the humidification space, the greater the duty cycle of the humidification fan. The smaller the difference between the current humidity and the set humidity in the humidification space, the smaller the duty cycle of the humidification fan. When the difference is large, the humidification can be accelerated, and when the difference is small, the humidification can be slowed down to reduce insufficient or excessive humidification.

[0020] In some embodiments, when the difference ΔRH satisfies rh2>ΔRH≥rh3, after determining that the duty cycle of the humidification fan is D3, the method further includes:

[0022] The duty cycle of the humidification fan is determined according to ΔRHt.

[0023] When the difference between the current humidity and the set humidity in the humidification space meets the set range, the duty cycle of the humidification fan is more accurately controlled by starting the humidity difference according to the set time. When the difference between the current humidity and the set humidity in the humidification space is small, the humidification amount can be controlled more accurately, further reducing the situation of over-humidification or under-humidification.

[0024] In some embodiments, determining the duty cycle of the humidifying fan according to ΔRHt includes:

[0025] When rh4 < ΔRHt < rh5, determining that the duty cycle of the humidifying fan is D4; and / or

[0030] By making the duty cycle of the humidifying fan larger when the humidification amount is smaller within the set time, and making the duty cycle of the humidifying fan smaller when the humidification amount is larger within the set time, the humidification can be precisely controlled, reducing the situations of excessive humidification or insufficient humidification.

[0031] In some embodiments, D4 = D3.

[0032] In some embodiments, the method further includes:

[0033] When it is determined that the current humidity of the humidifying space is less than the set humidity plus Δrh, determining to start humidification, where Δrh is the set humidity threshold.

[0034] By setting the start condition of humidification to that the current humidity is less than the set humidity plus Δrh, starting humidification when the difference between the current humidity and the set humidity is small is reduced.

[0038] A second determination module, configured to determine the duty cycle of the humidifying fan according to ΔRH;

[0039] An operation module is used to operate the humidification fan according to the duty cycle to perform humidification.

[0040] By determining the duty cycle of the humidification fan according to the difference ΔRH between the current humidity and the set humidity in the humidification space, and operating the humidification fan for humidification according to the duty cycle, the duty cycle of the humidification fan can be flexibly adjusted according to the difference between the current humidity and the set humidity, thereby effectively reducing the situation of excessive humidification.

[0041] In some embodiments, the second determination module determines the duty cycle of the humidification fan according to ΔRH, for:

[0042] In the case of ΔRH ≥ rh1, the duty cycle of the humidification fan is determined to be D1; and / or

[0043] In the case of rh1>ΔRH≥rh2, the duty cycle of the humidification fan is determined to be D2; and / or

[0044] In the case of rh2>ΔRH≥rh3, the duty cycle of the humidification fan is determined to be D3;

[0046] The greater the difference between the current humidity and the set humidity in the humidification space, the greater the duty cycle of the humidification fan. The smaller the difference between the current humidity and the set humidity in the humidification space, the smaller the duty cycle of the humidification fan. When the difference is large, the humidification can be accelerated, and when the difference is small, the humidification can be slowed down to reduce insufficient or excessive humidification.

[0047] In some embodiments, the device for controlling humidification further comprises:

[0048] A calculation module, for periodically calculating the difference ΔRHt between the current humidity and the humidity before the set time after determining that the duty cycle of the humidification fan is D3 when the difference ΔRH satisfies rh2>ΔRH≥rh3;

[0049] The third determination module is used to determine the duty cycle of the humidification fan according to ΔRHt.

[0050] When the difference between the current humidity and the set humidity in the humidification space meets the set range, the duty cycle of the humidification fan is more accurately controlled by starting the humidity difference according to the set time. When the difference between the current humidity and the set humidity in the humidification space is small, the humidification amount can be controlled more accurately, further reducing the situation of over-humidification or under-humidification.

[0051] In some embodiments, the third determination module is configured to:

[0052] When rh4 < ΔRHt < rh5, determine that the duty ratio of the humidifying fan is D4; and / or

[0216] S1812. When ΔRHt≤rh4, the duty cycle of the humidification fan is determined to be D7.

[0217] S1813: The refrigeration equipment operates the humidification fan according to the duty cycle to perform humidification.

[0218] like Fig.19 As shown, the embodiment of the present disclosure also provides a device for controlling humidification, comprising:

[0219] The acquisition module 1901 is used to periodically acquire the current humidity of the humidification space.

[0220] The first determination module 1902 is used to determine the difference ΔRH between the current humidity and the set humidity in the humidification space when it is determined to start humidification.

[0221] The second determining module 1903 is used to determine the duty cycle of the humidifying fan according to ΔRH.

[0222] The operation module 1904 is used to operate the humidification fan according to the duty cycle to perform humidification.

[0223] By determining the duty cycle of the humidification fan according to the difference ΔRH between the current humidity and the set humidity in the humidification space, and operating the humidification fan for humidification according to the duty cycle, the duty cycle of the humidification fan can be flexibly adjusted according to the difference between the current humidity and the set humidity, thereby effectively reducing the situation of excessive humidification.

[0224] In some embodiments, the second determination module 1903 determines the duty cycle of the humidification fan according to ΔRH, for:

[0225] In the case of ΔRH ≥ rh1, the duty cycle of the humidification fan is determined to be D1. And / or

[0226] In the case of rh1>ΔRH≥rh2, the duty cycle of the humidification fan is determined to be D2. And / or in the case of rh2>ΔRH≥rh3, the duty cycle of the humidification fan is determined to be D3.

[0227] Among them, rh1 is the first humidity range, rh2 is the second humidity range, rh3 is the third humidity range, rh1>rh2>rh3, D1 is the first duty cycle value, D2 is the second duty cycle value, D3 is the third duty cycle value, D1>D2>D3.

[0228] The greater the difference between the current humidity and the set humidity in the humidification space, the greater the duty cycle of the humidification fan. The smaller the difference between the current humidity and the set humidity in the humidification space, the smaller the duty cycle of the humidification fan. When the difference is large, the humidification can be accelerated, and when the difference is small, the humidification can be slowed down to reduce insufficient or excessive humidification.

[0229] In some embodiments, Fig.19 As shown, the device for controlling humidification also includes:

[0230] The calculation module 1905 is used to periodically calculate the difference ΔRHt between the current humidity and the humidity before the set time after the set time after determining that the duty cycle of the humidification fan is D3 when the difference ΔRH satisfies rh2>ΔRH≥rh3.

[0231] The third determination module 1906 is configured to determine the duty cycle of the humidification fan according to ΔRHt.

[0232] When the difference between the current humidity and the set humidity in the humidification space meets the set range, the duty cycle of the humidification fan is more accurately controlled by starting the humidity difference according to the set time. When the difference between the current humidity and the set humidity in the humidification space is small, the humidification amount can be controlled more accurately, further reducing the situation of over-humidification or under-humidification.

[0233] In some implementations, the third determining module 1906 is configured to:

[0234] In the case of rh4<ΔRHt<rh5, the duty cycle of the humidification fan is determined to be D4. And / or

[0235] In the case of rh6>ΔRHt≥rh5, the duty cycle of the humidification fan is determined to be D5. And / or in the case of ΔRHt≥rh6, the duty cycle of the humidification fan is determined to be D6. And / or

[0236] When ΔRHt≤rh4, the duty cycle of the humidification fan is determined to be D7;

[0237] Among them, rh4 is the fourth humidity range, rh5 is the fifth humidity range, rh6 is the sixth humidity range, rh4 < rh5 < rh6, D4 is the fourth duty ratio, D5 is the fifth duty ratio, D6 is the sixth duty ratio, D7 is the seventh duty ratio, and D6 < D5 < D4 < D7.

[0238] By making the humidification amount smaller within a set time, the duty ratio of the humidification fan is made larger. By making the humidification amount larger within a set time, the duty ratio of the humidification fan is made smaller. Humidification can be precisely controlled, reducing the situations of excessive humidification or insufficient humidification.

[0239] In some embodiments, D4 = D3.

[0240] In some embodiments, the device for controlling humidification further includes:

[0241] A fourth determination module 1907, configured to determine to start humidification when it is determined that the current humidity in the humidification space is less than the set humidity plus Δrh, where Δrh is a set humidity threshold.

[0242] By setting the start condition of humidification to that the current humidity is less than the set humidity plus Δrh, starting humidification when the difference between the current humidity and the set humidity is small is reduced. The situation of excessive humidification is further reduced.
