Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an adaptive dehumidification method for a cigar cabinet and a cigar cabinet. Background Technology

[0002] Currently, constant temperature and humidity air conditioning systems are being used in more and more fields, such as electronics, hospitals, metrology, textiles and optical instruments, food, and especially in fields with stringent environmental requirements, such as cigars and wine. Generally, a device is installed to ensure that the above products are in a constant temperature and humidity environment. For example, a cigar cabinet is a constant temperature and humidity refrigeration appliance used to preserve cigars.

[0003] Cigar cabinets typically require a constant temperature and humidity environment of 16–22℃ and 65–75%RH to ensure the quality and flavor of cigars. Most cigar cabinets in the industry consist of a fixed-frequency compressor refrigeration (dehumidification) system, a humidification system, an air circulation system, and a control system.

[0004] Currently, when a cigar cabinet starts dehumidifying, the compressor runs at a fixed speed, the evaporator's cooling capacity is fixed, and therefore the dehumidification capacity is also fixed. However, in reality, the required dehumidification capacity varies depending on different operating conditions (external environment, the dryness and humidity of the cigars inside). Fixed-frequency compressors and semiconductor refrigeration systems cannot adapt to all operating conditions. For example, when the door is closed for a long time and the ambient temperature is constant, the cigar cabinet needs to operate for a short time with a small dehumidification capacity; when a large number of damp cigars are placed inside, the cigar cabinet needs to operate for a long time with a large dehumidification capacity; and when the door is opened in a high-temperature and high-humidity environment, the cigar cabinet needs to operate for a short time with a large dehumidification capacity. For these operating conditions, semiconductor refrigeration systems and fixed-frequency compressors cannot adaptively adjust. Summary of the Invention

[0005] This application provides an adaptive dehumidification method and cigar cabinet to solve the technical problem that existing cigar cabinets cannot adaptively adjust the semiconductor refrigeration system and fixed-frequency compressor for different operating conditions when starting dehumidification.

[0006] The first aspect of this application provides an adaptive dehumidification method for a cigar cabinet, comprising:

[0007] Obtain the first real-time humidity level of the cigar cabinet;

[0008] If the first real-time humidity is greater than the humidity activation preset threshold, then the difference between the first real-time humidity and the humidity activation preset threshold is calculated; if the difference is greater than the first humidity setting difference and less than the second humidity setting difference, then the compressor is controlled to run at the first speed and the heater at the first power simultaneously.

[0009] The compressor and heater are obtained after a preset operating time period. If the second real-time humidity does not reach the preset humidity shut-off threshold, the compressor is controlled to run at the second speed input by the speed model and the heater is controlled to run at the second power input by the power model until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold, at which point the compressor and heater stop running simultaneously.

[0010] In some embodiments, the first rotational speed is: n i =n1*(1+△H / A), where n1 is the minimum speed of the compressor required for dehumidification operation in the cigar cabinet; △H is the difference between the real-time humidity and the preset humidity threshold; A is the first humidity setting difference; and the first power is: W i =W1*(1+△H / A), where W1 is the minimum power required for the dehumidification heater in the cigar cabinet.

[0011] In some embodiments, the rotational speed model is: N j =n i +N, where N j For the second rotational speed, n i As the first rotational speed, N increases by 30 r / min every preset operating time interval until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold, at which point the compressor stops operating; the power model is: W j =W i +M, where W j For the second power, W i The initial power is M, which increases by 10W every preset operating time period until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold, at which point the heater stops operating.

[0012] In some embodiments, the step of stopping the compressor and heater simultaneously after the real-time humidity of the cigar cabinet reaches a preset humidity shut-off threshold includes:

[0013] Obtain the running time of the compressor from the first speed to the point of stopping;

[0014] The running time of the storage compressor from the first speed to the stop, and the difference between the real-time humidity and the preset humidity threshold;

[0015] If the real-time humidity of the cigar cabinet does not reach the preset humidity shut-off threshold after the compressor and heater have been running for a preset period of time, it is determined whether there is a common value between the real-time humidity and the preset humidity opening threshold. If so, the running time of the compressor at the first speed until it stops running is obtained, corresponding to the difference between the real-time humidity and the preset humidity opening threshold.

[0016] Based on the operating time of the compressor from its first speed to its stop, the compressor is controlled to operate at a third speed and the heater at a third power until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold, at which point both the compressor and heater stop operating simultaneously; the third speed is: N i+1 =n1+n1*[(t' / t)-1]; where t' is the running time of the compressor from the first speed to the stop, and t is a preset time period; the third power is: W i+1 =W1+W1*[(t' / t)-1].

[0017] In some embodiments, the method further includes:

[0018] Get the real-time humidity of the cigar cabinet;

[0019] If the real-time humidity is less than the preset threshold for humidifying the system to start, the humidifying system will start until the real-time humidity is greater than the preset threshold for shutting down the humidifying system, at which point the humidifying system will stop operating.

[0020] In some embodiments, the step of calculating the difference between the first real-time humidity and the preset humidity activation threshold if the first real-time humidity is greater than the preset humidity activation threshold includes:

[0021] If the difference is greater than 0 and less than the first humidity setting difference, the compressor is controlled to run at the minimum speed required for dehumidification of the cigar cabinet, and the heater is simultaneously operated at the minimum power required for dehumidification of the cigar cabinet, until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold, at which point the compressor and heater stop operating.

[0022] In some embodiments, after obtaining the first real-time humidity of the cigar cabinet, the process includes:

[0023] If the first real-time humidity is less than the preset threshold for humidity activation, then the compressor and heater will be stopped.

[0024] In some embodiments, after the compressor is controlled to operate at a first speed and the heater is simultaneously operated at a first power, the following steps are included:

[0025] If the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold within the preset operating time period, the compressor and heater will be controlled to stop operating.

[0026] The second aspect of this application provides a cigar cabinet that implements the adaptive dehumidification method for a cigar cabinet as described in any one of the first aspects above, comprising:

[0027] Cigar cabinet body;

[0028] Cigar cabinet door, which is rotatably connected to the cigar cabinet body;

[0040] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in 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 in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0041] In some technologies, when a cigar cabinet begins dehumidification, the semiconductor refrigeration system and the fixed-frequency compressor cannot adaptively adjust to different operating conditions. To solve this technical problem, this application provides an adaptive dehumidification method for a cigar cabinet and a cigar cabinet itself. The adaptive dehumidification method and the cigar cabinet are described below:

[0042] Depend on Figure 1 As can be seen, the adaptive dehumidification method for a cigar cabinet provided in this application includes: obtaining a first real-time humidity H1 of the cigar cabinet; obtaining the current humidity parameter of the cigar cabinet, i.e., the first real-time humidity H1, using a temperature and humidity sensor; after obtaining the first real-time humidity H1 of the cigar cabinet, the method includes: if the first real-time humidity H1 is less than a preset humidity activation threshold H... on The humidity activation preset threshold H on If a manually set relative humidity value is less than the required range for the cigar cabinet, the compressor and heater will stop operating, indicating that the humidity inside the cigar cabinet meets the relative humidity requirement. The preset humidity threshold H... on The minimum relative humidity requirement for a cigar cabinet is as follows: the temperature inside a cigar cabinet should generally be within the range of 16 to 22°C, with a temperature fluctuation of ±1°C; the relative humidity should be within the range of 65 to 75%, with a humidity fluctuation of ±5%. The smaller the fluctuation in temperature and humidity, the better for the storage of cigars.

[0043] If the first real-time humidity H1 is greater than the humidity activation preset threshold H on Then calculate the first real-time humidity H1 and the humidity activation preset threshold H. on The difference ΔH, ΔH = H1 - H on If the first real-time humidity H1 is greater than the humidity activation preset threshold H, then... on Then calculate the first real-time humidity H1 and the humidity activation preset threshold H. onAfter the difference ΔH, the following steps are taken: If the difference is greater than 0 and less than the first humidity setting difference, i.e., 0 < ΔH < A, where the first humidity setting difference is a manually set value, determined according to the required humidity for the type of cigars in the cigar cabinet, then the compressor is controlled to operate at the minimum speed n1 required for dehumidification of the cigar cabinet, and the heater operates simultaneously at the minimum power W1 required for dehumidification of the cigar cabinet, until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold H. off The humidity shut-off preset threshold H off The system sets a value based on the relative humidity requirement of the cigar cabinet, and the compressor and heater stop operating. It can be understood that when 0 < ΔH < A, the humidity inside the cigar cabinet is close to the minimum relative humidity requirement. In this case, the compressor operates at its minimum dehumidification speed n1, and the heater operates at its minimum dehumidification power W1, until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold H. off That's it. If the difference is greater than the first humidity setting difference and less than the second humidity setting difference, i.e., A < ΔH < B, where the second humidity setting difference is a manually set value, and generally the difference will not exceed the second humidity setting difference, then control the compressor to operate at the first speed n. i The heater operates at a first power of W. i Simultaneous operation; the control compressor operates at a first speed n i The heater operates at its first power W. i After simultaneous operation, including: if the compressor and heater reach the preset humidity shut-off threshold H within the preset operating time period t, the cigar cabinet's real-time humidity will be within this threshold. off Then, the compressor and heater will stop running, and the humidity inside the cigar cabinet will reach the required relative humidity. The first rotational speed is: n i =n1*(1+△H / A), where n1 is the minimum speed of the compressor required for dehumidification operation in the cigar cabinet; △H is the difference between the real-time humidity and the preset humidity threshold; A is the first humidity setting difference; and the first power is: W i =W1*(1+△H / A), where W1 is the minimum power required for the dehumidification heater in the cigar cabinet.

[0044] Obtain the second real-time humidity H2 after the compressor and heater have been running for a preset period of time. If the second real-time humidity H2 has not reached the humidity shutdown preset threshold H... off Then the compressor is controlled according to the second speed N input by the speed model. j The heater receives the second power W according to the power model. jSimultaneously, the speed model is used to generate speed parameter values, which are input to the compressor to control its operation; the power model is used to generate power parameter values, which are input to the heater to control its operation, until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold, at which point the compressor and heater simultaneously stop operating. The speed model is: N j =n i +N, where N j For the second rotational speed, n i For the first rotational speed, N increases by 30 r / min every preset operating time period t until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold H. off The compressor stops running; the power model is: W j =W i +M, where W j For the second power, W i As the initial power, M increases by 10W every preset operating time period t until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold H. off The heater stops operating. Understandably, the speed model increases the compressor's minimum speed n1 required for dehumidification in the cigar cabinet by 30 r / min every preset operating time period t. That is, after the first preset operating time period t, the second speed increases by 30 r / min based on n1; after the second preset operating time period t, the second speed increases by 60 r / min based on n1. Simultaneously, the power model increases the heater's minimum power W1 required for dehumidification in the cigar cabinet by 10 W every preset operating time period t. That is, after the first preset operating time period t, the second power increases by 10 W based on W1; after the second preset operating time period t, the second power increases by 20 W based on W1; until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold H. off The heater stops operating. This indicates that the cigar cabinet experiences a high humidity load within a short period, requiring rapid dehumidification. Therefore, the compressor and heater power needs to be adjusted according to the dehumidification time. Increasing the compressor speed proportionally lowers the evaporator temperature and improves its dehumidification capacity; simultaneously increasing the heater power compensates for temperature fluctuations caused by the evaporator temperature reduction.

[0045] The process continues until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold, at which point the compressor and heater simultaneously stop operating, including: obtaining the compressor speed n. iThe running time t' from start to stop; that is, the running time t' from the start of the compressor to the stop of the humidification process; the running time t' of the storage compressor running at the first speed to stop, and the corresponding difference ΔH between the real-time humidity and the preset humidity threshold; when the compressor and heater have been running for the preset time period t, the real-time humidity of the cigar cabinet has not reached the preset humidity threshold H. off Determine if there is a value that is the same as the difference between the real-time humidity and the preset humidity threshold. If so, obtain the compressor corresponding to the difference ΔH between the real-time humidity and the preset humidity threshold at a first speed n. i The running time t' from start to finish; based on the compressor operating at a first speed n i During the running time t' from start to finish, the compressor is controlled to run at the third speed N. i+1 Operation, heater at third power W i+1 Run until the real-time humidity of the cigar cabinet reaches the preset humidity shut-off threshold H. off The compressor and heater stop operating simultaneously; the third rotational speed is: N i+1 =n1+n1*[(t' / t)-1]; where t' is the running time of the compressor from the first speed to the stop, and t is a preset time period; the third power is: W i+1 =W1 + W1*[(t' / t) - 1]. It is understandable that if the stored real-time humidity and the difference between the humidity activation preset threshold are the same, then the compressor and heater will directly operate at the third speed N. i+1 and the third power W i+1 Simply run it; there's no need to input the second speed N using the speed model and power model. j Second power W j This improves the dehumidification efficiency of the cigar cabinet.

[0046] The method further includes: acquiring the real-time humidity of the cigar cabinet; if the real-time humidity is less than a preset threshold for activating the humidification system, then activating the humidification system until the real-time humidity exceeds a preset threshold for deactivating the humidification system, at which point the humidification system stops operating. The preset thresholds for activating and deactivating the humidification system are manually set values, determined based on the type of cigar and the required humidity. It can be understood that when the real-time humidity of the cigar cabinet is less than the required relative humidity, humidification is needed; when the real-time humidity is less than the preset threshold for activating the humidification system, it indicates that the humidity inside the cigar cabinet needs to be increased, so the humidification system is activated until the real-time humidity exceeds the preset threshold for deactivating the humidification system, at which point the humidification system stops operating, completing the humidification operation of the cigar cabinet.
