Description

Technical Field

[0001] This invention relates to the field of cigarette storage technology, and in particular to an operation control method for a temperature-controlled dehumidifier and a temperature-controlled dehumidifier. Background Technology

[0002] According to the requirements of cigarette production processes, tobacco leaves for cigarettes need to be aged in tobacco warehouses for 1-3 years. As the storage location for tobacco leaves, the temperature and humidity of the storage environment in tobacco warehouses must be controlled to provide suitable environmental conditions for tobacco storage. If the temperature and humidity of the storage environment are too high, the tobacco leaves are prone to blackening and mold growth. Therefore, temperature and humidity control units are usually used in tobacco warehouses to control the temperature and humidity to meet the storage environment requirements of the tobacco leaves.

[0003] In the existing technology, once the temperature and humidity control dehumidifier is started, it will continue to run unless manually turned off. When the temperature and humidity in the tobacco warehouse need to be adjusted or meet the requirements, it cannot automatically start or stop, resulting in high energy consumption and shortening the service life of the device. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of high energy consumption and short service life of existing cooling and dehumidifying machines. This invention provides an operation control method and a temperature-controlled dehumidifying machine that can automatically select the appropriate operating mode according to the temperature and humidity in the tobacco warehouse, and can automatically enter standby mode when temperature and humidity adjustment is not required, thereby reducing energy consumption and increasing the service life of the device.

[0005] To address the aforementioned technical problems, embodiments of the present invention disclose an operation control method for a temperature-regulating dehumidifier. The temperature-regulating dehumidifier includes an evaporator and a dehumidifier. The evaporator is used to lower the temperature of the air in the workshop, and the dehumidifier is used to lower the humidity of the air in the workshop. The operation control method includes:

[0006] Collect the return air temperature and humidity at the return air vent of the temperature-controlled dehumidifier;

[0007] Determine if the return air temperature is greater than or equal to the first preset temperature;

[0008] If so, the temperature-controlled dehumidifier will enter cooling mode. In cooling mode, the evaporator will start and the dehumidifier will turn off.

[0009] If not, determine whether the return air humidity is greater than or equal to the first preset humidity;

[0010] When the return air humidity is lower than the first preset humidity, the temperature-controlled dehumidifier enters standby mode and stops working in standby mode.

[0011] When the return air humidity is greater than or equal to the first preset humidity, determine whether the return air temperature is within the preset temperature range;

[0012] If the return air temperature is within the preset temperature range, the temperature-controlled dehumidifier enters the temperature-controlled dehumidification mode. In the temperature-controlled dehumidification mode, both the dehumidifier and the evaporator are started, and the evaporator operates at the first power.

[0013] If the return air temperature is greater than the maximum value within the preset temperature range, the temperature-regulating dehumidifier enters the cooling and dehumidification mode. In the cooling and dehumidification mode, both the dehumidifier and the evaporator are started, and the evaporator operates at the second power, which is greater than the first power.

[0014] If the return air temperature is lower than the minimum value within the preset temperature range, the temperature-regulating dehumidifier will enter standby mode.

[0015] According to another specific embodiment of the present invention, when the temperature-controlled dehumidifier enters the cooling dehumidification mode or the temperature-controlled dehumidification mode, it is determined whether the return air humidity is less than or equal to the second preset humidity. If so, the temperature-controlled dehumidifier enters the standby mode; wherein, the second preset humidity is less than the first preset humidity.

[0016] According to another specific embodiment of the present invention, before determining whether the return air temperature is greater than or equal to the first preset temperature, the method further includes: the temperature-controlled dehumidifier entering the ventilation mode, in which the air outlet of the temperature-controlled dehumidifier begins to introduce air into the workshop, and when the ventilation mode continues for the first preset time, the temperature-controlled dehumidifier exits the ventilation mode.

[0017] According to another specific embodiment of the present invention, it further includes:

[0018] When the temperature-controlled dehumidifier enters standby mode, the timer starts.

[0019] Determine whether the temperature-controlled dehumidifier remains in standby mode for the second preset time;

[0020] If so, the temperature-controlled dehumidifier will exit standby mode and enter ventilation mode;

[0021] If not, the temperature-controlled dehumidifier will continue to operate in standby mode.

[0022] According to another specific embodiment of the present invention, the maximum value of the preset temperature range is a second preset temperature, and the minimum value of the preset temperature range is a third preset temperature; wherein, the second preset temperature is less than the first preset temperature.

[0023] According to another specific embodiment of the present invention, the second preset humidity is the first preset humidity minus the preset humidity error.

[0024] Embodiments of the present invention also provide a temperature-regulating dehumidifier for implementing the operation control method described in any of the foregoing claims, comprising:

[0025] The airflow channel has an air supply outlet and a return air outlet at each end. The air supply outlet is used to supply air into the workshop, and the return air outlet is used to draw air from the workshop into the airflow channel.

[0026] An evaporator, located within an airflow channel, is used to reduce the temperature of the air within the airflow channel.

[0027] A dehumidifier, located within an airflow channel, is used to reduce the humidity of the air within that channel.

[0028] The detection unit is used to detect return air temperature and return air humidity;

[0029] The control unit is electrically connected to the detection unit, evaporator, and dehumidifier respectively. The control unit can control the start and stop of the evaporator and dehumidifier according to the return air temperature and return air humidity values.

[0030] According to another specific embodiment of the present invention, it further includes:

[0031] The compressor is located outside the airflow passage;

[0032] The condenser is located outside the airflow channel;

[0033] The compressor, condenser, and evaporator are connected end to end through refrigerant pipelines to form a refrigerant circulation path.

[0034] According to another specific embodiment of the present invention, the detection unit includes:

[0035] A temperature sensor is located at the return air vent and is used to detect the return air temperature.

[0036] A humidity sensor is located at the return air vent and is used to detect the humidity of the return air.

[0037] Both the temperature sensor and the humidity sensor are electrically connected to the control unit, and the temperature sensor and humidity sensor can output the values ​​of return air temperature and return air humidity to the control unit.

[0038] According to another specific embodiment of the present invention, a fan is also included, which is disposed in the airflow channel on the side near the air outlet. The fan is used to deliver the air in the airflow channel to the workshop through the air outlet.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] This invention determines whether a temperature-controlled dehumidifier should enter standby mode by collecting return air temperature and humidity data. When the return air temperature is lower than a first preset temperature, and the return air humidity is also lower than the first preset humidity, the temperature-controlled dehumidifier enters standby mode. If the return air humidity is greater than or equal to the first preset humidity, but the return air temperature is lower than the minimum value within the preset temperature range, the temperature-controlled dehumidifier also enters standby mode. The implementation method provided by this invention allows the temperature-controlled dehumidifier to automatically enter standby mode, saving energy, reducing energy consumption, and extending the device's lifespan. Furthermore, this invention sets temperature-controlled dehumidification mode and cooling dehumidification mode. If the return air temperature is within the preset temperature range, the temperature-controlled dehumidifier enters temperature-controlled dehumidification mode, in which the evaporator operates at low power. If the return air temperature is greater than the maximum value within the preset temperature range, the temperature-controlled dehumidifier enters cooling dehumidification mode, in which the evaporator operates at high power. This invention further saves energy by allowing the evaporator to operate at different power levels in different operating modes. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0051] Embodiments of the present invention provide an operation control method for a temperature-controlled dehumidifier, such as... Figure 2 As shown, the temperature-regulating dehumidifier includes an evaporator 2 and a dehumidifier 3. The evaporator 2 is used to lower the temperature of the air in the workshop, and the dehumidifier 3 is used to lower the humidity of the air in the workshop. The temperature-regulating dehumidifier also has an air supply outlet 11 and an air return outlet 12. The operation control method for the temperature-regulating dehumidifier provided in this embodiment (such as...) Figure 1 (As shown) includes:

[0052] The return air temperature and humidity were collected at 12 return air inlets of the temperature-controlled dehumidifier;

[0053] Determine whether the return air temperature is greater than or equal to the first preset temperature T1;

[0054] If so, the temperature-regulating dehumidifier enters the cooling mode. In the cooling mode, the evaporator 2 starts and the dehumidifier 3 turns off. The cooling mode is used to reduce the temperature of the air in the workshop, thereby reducing the return air temperature.

[0055] If not, determine whether the return air humidity is greater than or equal to the first preset humidity RH;

[0056] When the return air humidity is less than the first preset humidity RH, the temperature-controlled dehumidifier enters the standby mode. In the standby mode, the temperature-controlled dehumidifier stops working;

[0057] When the return air humidity is greater than or equal to the first preset humidity RH, determine whether the return air temperature is within the preset temperature range;

[0058] If the return air temperature is within the preset temperature range, the temperature-controlled dehumidifier enters the temperature-controlled dehumidification mode. In the temperature-controlled dehumidification mode, both the dehumidifier 3 and the evaporator 2 are started, and the evaporator 2 operates at the first power;

[0059] If the return air temperature is greater than the maximum value within the preset temperature range, the temperature-controlled dehumidifier enters the cooling dehumidification mode. In the cooling dehumidification mode, both the dehumidifier 3 and the evaporator 2 are started, and the evaporator 2 operates at the second power, where the second power is greater than the first power;

[0060] If the return air temperature is less than the minimum value within the preset temperature range, the temperature-controlled dehumidifier is made to enter the standby mode.

[0061] Specifically, the maximum value of the preset temperature range is the second preset temperature T2, and the minimum value of the preset temperature range is the third preset temperature T3, where T1 > T2 > T3. In the present invention, the return air temperature is divided into four temperature ranges by the first preset temperature T1, the second preset temperature T2, and the third preset temperature T3, which are: high temperature range, medium-high temperature range, medium-low temperature range, and low temperature range. Among them, the medium-low temperature range is the preset temperature range mentioned above. When the return air temperature is greater than or equal to T1, the return air temperature is in the high temperature range, and at this time, the temperature in the workshop is close to the high temperature critical value. When T2 < return air temperature < T1, the return air temperature is in the medium-high temperature range, and at this time, the temperature in the workshop is relatively high. When T3 ≤ return air temperature ≤ T2, the return air temperature is in the medium-low temperature range, and at this time, the temperature in the workshop is within the preset temperature range. When the return air temperature is less than T3, the return air temperature is in the low temperature range, and at this time, the temperature in the workshop is close to the low temperature critical value. Specifically, the first preset humidity RH is the qualified value of the humidity in the workshop.

[0062] Since the influence of humidity on the quality of tobacco leaves is much greater than that of temperature, when the humidity in the workshop meets the requirements, as long as the temperature in the workshop is not too high or too low, that is, the temperature is not close to the high temperature critical value or the low temperature critical value, the temperature can be not adjusted.

[0063] Using the above technical solution, the system collects return air temperature and humidity data to determine whether the temperature-regulating dehumidifier should enter standby mode. When the return air temperature is lower than the first preset temperature T1 and the return air humidity is lower than the first preset humidity RH, it indicates that the temperature in the workshop is not too high and the humidity meets the requirements, so dehumidification is not necessary. In this case, the temperature-regulating dehumidifier enters standby mode. If the return air humidity is greater than or equal to the first preset humidity RH, but the return air temperature is lower than the minimum value within the preset temperature range (i.e., the return air temperature is lower than the third preset temperature T3), it indicates that the temperature in the workshop is approaching the low-temperature critical value, and further cooling is not possible. In this case, the temperature-regulating dehumidifier also enters standby mode. The implementation method provided by this invention allows the temperature-regulating dehumidifier to automatically enter standby mode, thereby saving energy, reducing energy consumption, and extending the service life of the device.

[0064] Furthermore, this invention sets up a temperature-regulating dehumidification mode and a cooling dehumidification mode. If the return air humidity is greater than or equal to the first preset humidity RH and the return air temperature is within the preset temperature range, it indicates that the temperature inside the workshop is within the preset temperature range, but the humidity does not meet the requirements. In this mode, the temperature-regulating dehumidifier enters the temperature-regulating dehumidification mode, where the evaporator 2 operates at low power to fine-tune the temperature, thereby saving energy. If the return air humidity is greater than or equal to the first preset humidity RH and the return air temperature is greater than the maximum value within the preset temperature range (i.e., the return air temperature is greater than the second preset temperature T2), it indicates that the temperature inside the workshop is high and the humidity does not meet the requirements. In this mode, the temperature-regulating dehumidifier enters the cooling dehumidification mode, where the evaporator 2 operates at high power to quickly reduce the temperature inside the workshop. This invention further saves energy by allowing the evaporator 2 to operate at different power levels in different working modes.

[0065] Furthermore, after the temperature-controlled dehumidifier enters the cooling mode, it continuously monitors the return air temperature and determines whether the return air temperature is lower than the second preset temperature T2. If not, it continues in the cooling mode; if so, it exits the cooling mode.

[0066] Furthermore, when the temperature-controlled dehumidifier enters either cooling / dehumidification mode or temperature-controlled dehumidification mode, it checks whether the return air humidity is less than or equal to the second preset humidity. If so, the temperature-controlled dehumidifier enters standby mode. The second preset humidity is less than the first preset humidity (RH). Specifically, the second preset humidity is the first preset humidity (RH) minus the preset humidity error ΔRH.

[0067] Using the above technical solution, it is possible to determine whether a temperature-controlled dehumidifier should switch from cooling dehumidification mode or temperature-controlled dehumidification mode to standby mode. When the temperature-controlled dehumidifier enters cooling dehumidification mode or temperature-controlled dehumidification mode, if the return air humidity is less than or equal to the second preset humidity RH-ΔRH, it indicates that the humidity in the workshop is approaching the critical value and dehumidification can no longer continue. At this time, the temperature-controlled dehumidifier enters standby mode.

[0068] Optionally, refer to Figure 1 Before determining whether the return air temperature is greater than or equal to the first preset temperature T1, the process further includes: the temperature-regulating dehumidifier entering a ventilation mode. In the ventilation mode, the air outlet 11 of the temperature-regulating dehumidifier begins to introduce air into the workshop. When the ventilation mode continues for the first preset time, the temperature-regulating dehumidifier exits the ventilation mode. This invention, by setting a ventilation mode, facilitates the introduction of air into the workshop to adjust the temperature and humidity within the workshop, ensuring that the temperature and humidity meet the requirements.

[0069] Optionally, the operation control method for a temperature-regulating dehumidifier provided by the present invention further includes:

[0070] When the temperature-controlled dehumidifier enters standby mode, the timer starts.

[0071] Determine whether the temperature-controlled dehumidifier remains in standby mode for the second preset time;

[0072] If so, the temperature-controlled dehumidifier will exit standby mode and enter ventilation mode;

[0073] If not, the temperature-controlled dehumidifier will continue to run in standby mode.

[0074] refer to Figure 2 The present invention also provides a temperature-controlled dehumidifier for implementing the operation control method for a temperature-controlled dehumidifier described in any of the preceding claims. The temperature-controlled dehumidifier includes an airflow channel 1, an evaporator 2, a dehumidifier 3, a detection unit 4, and a control unit (not shown in the figure). An air supply port 11 and a return air port 12 are respectively provided at both ends of the airflow channel 1. The air supply port 11 is used to supply air into the workshop, and the return air port 12 is used to draw air from the workshop into the airflow channel 1. The evaporator 2 is disposed within the airflow channel 1 and is used to reduce the temperature of the air within the airflow channel 1. The dehumidifier 3 is disposed within the airflow channel 1 and is used to reduce the humidity of the air within the airflow channel 1. The detection unit 4 is used to detect the return air temperature and return air humidity. For example, refer to... Figure 2The detection unit 4 includes a temperature sensor 41 and a humidity sensor 42 located at the return air vent 12. The temperature sensor 41 detects the return air temperature, and the humidity sensor 42 detects the return air humidity. Both the temperature sensor 41 and the humidity sensor 42 are electrically connected to the control unit, and can output the values ​​of the return air temperature and humidity to the control unit. The control unit is electrically connected to the detection unit 4, the evaporator 2, and the dehumidifier 3, respectively, and can control the start and stop of the evaporator 2 and the dehumidifier 3 based on the values ​​of the return air temperature and humidity.

[0075] When the return air temperature and humidity values ​​detected by the detection unit indicate that the temperature-regulating dehumidifier should enter standby mode, the control unit stops both evaporator 2 and dehumidifier 3. When the temperature-regulating dehumidifier should enter cooling dehumidification mode or temperature-regulating dehumidification mode, the control unit starts both evaporator 2 and dehumidifier 3. When the temperature-regulating dehumidifier should enter cooling mode, the control unit starts evaporator 2 and stops dehumidifier 3.

[0076] Optionally, refer to Figure 2 The temperature-regulating dehumidifier provided in the embodiments of the present invention further includes a compressor 5 and a condenser 6. Both the compressor 5 and the condenser 6 are located outside the airflow channel 1, and the compressor 5, the condenser 6, and the evaporator 2 are connected end to end through a refrigerant pipeline 7 to form a refrigerant circulation path. Refrigerant flows through the refrigerant pipeline 7; for example, the refrigerant may be a refrigerant.

[0077] The present invention sets up a refrigerant circulation path consisting of a compressor 5, a condenser 6 and an evaporator 2, so that the evaporator 2 located in the airflow channel 1 can absorb the heat in the airflow channel 1, thereby reducing the temperature of the gas in the airflow channel 1 and thus achieving the purpose of reducing the temperature in the workshop.

[0078] Optionally, refer to Figure 2 It also includes a fan 8, located within the airflow channel 1 near the air outlet 11. The fan 8 is used to deliver air from the airflow channel 1 to the workshop through the air outlet 11. When the temperature-regulating dehumidifier is in ventilation mode, the fan 8 starts, beginning to introduce air into the workshop. This invention, by installing the fan 8 at the air outlet 11, facilitates the delivery of gas from the airflow channel 1 to the workshop, thereby adjusting the temperature and humidity within the workshop.

[0079] While the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the invention to these descriptions. Various changes in form and detail can be made by those skilled in the art, including several simple deductions or substitutions, without departing from the spirit and scope of the invention.
