Detailed Description
Referring to fig. 1 to 2 in combination, according to an embodiment of the present invention, a dehumidification control method includes
Acquiring a humidity value and a temperature value of a target environment;
determining the optimal air supply quantity of the dehumidification equipment according to the humidity value and the temperature value;
the dehumidification equipment is regulated and controlled to operate at the optimal air supply quantity.
According to the embodiment of the invention, the humidity and the temperature of the target environment are detected, the optimal air supply quantity corresponding to the dehumidifying equipment is determined according to the detected temperature and humidity, and the dehumidifying equipment is controlled to operate in the mode of the optimal air supply quantity, so that the dehumidifying equipment can effectively dehumidify.
For the temperature and humidity of the environment where the specific dehumidification equipment is combined, when the air supply quantity is zero, the dehumidification quantity is zero, and when the air supply quantity is gradually increased, the dehumidification quantity is increased, but the higher the air supply quantity is, the better the air supply quantity is, the optimal air supply quantity exists, and the dehumidification quantity is the maximum at the moment. When the air supply amount is higher than the optimal air supply amount, the dehumidification amount starts to decrease, namely, the dehumidification amount changes in a parabola shape along with the change process of the air supply amount from small to large.
The invention aims at the shaped dehumidification equipment, the corresponding optimal air supply quantity can be determined only by detecting the humidity and the temperature of the environment by utilizing the characteristics of the dehumidification equipment such as condensation efficiency, if the optimal air supply quantity is exceeded, the dehumidification equipment possibly cannot reach the condensed humid air, but can cause the reduction of the dehumidification quantity, and the dehumidification equipment can play the optimal operation level by adopting the optimal air supply quantity, thereby improving the dehumidification capability.
As for each formed dehumidifier, the structure and the size of all parts are fixed, such as the blade shape size of the fan 8 and the like, at the moment, the air supply quantity only has a positive corresponding relation with the rotating speed of the fan 8, as shown in figure 2, the functional relation between the air supply quantity and the rotating speed of the motor is obtained by fitting calculation when the air supply quantity condition of a dehumidifier with a specific structure is measured at different rotating speeds: v-0.3396 ω -63.544; where V is the air output and ω is the rotational speed.
For the dehumidifier with a similar specific structure, the adjustment of the air supply quantity can be realized only by controlling the rotating speed of the motor, and the corresponding function relation is set in the controller 5, so that the corresponding air supply quantity state can be obtained by adjusting the rotating speed of the motor.
The specific way of adjusting the optimum rotation speed is,in the formula: omega is the optimal rotating speed, and the rotating speed is controlled by the controller,is an ambient humidity value; t is an ambient temperature value; a. b, c and d are constants and are related to the characteristics of the dehumidification equipment; after the structure of the dehumidification equipment is set, the four constants are determined values.
Using detected ambient temperature (T), relative humidityThe corresponding optimal rotating speed of the fan 8 can be calculated by substituting the function into a proposed function, and the dehumidification amount of the dehumidifier is kept at a better level by adjusting the rotating speed of the motor. In the practical use of the dehumidifier, the environmental humidity and the environmental temperature gradually change along with the operation of the dehumidifier, and the rotating speed of the motor of the dehumidifier gradually adapts to the change, so that the dehumidification amount is always at a higher level, and the practical dehumidification effect can be greatly improved.
The ambient humidity and the ambient temperature may change either one of them or both of them, and at this time, it is necessary to determine the optimum air supply amount or the optimum rotation speed of the dehumidification equipment again, and regulate and control the dehumidification equipment to operate at the determined optimum air supply amount or optimum rotation speed.
For example, under the condition of constant ambient temperature and high humidity, a large amount of air supply or fan rotation speed is needed, a large amount of air is dehumidified rapidly through an evaporator, and the humidity can be reduced rapidly; when the humidity is gradually reduced, the dew point of the air is low, the air needs lower air quantity, the air is slowly blown out after being fully condensed by ensuring full contact with the evaporator, and the humidity can be further reduced.
The dehumidification process is only operated in relation to the excess of the ambient humidity, so that the operation of the dehumidification device is stopped when the ambient humidity reaches the preset humidity value threshold range.
By adopting the dehumidification control method, the dehumidification operation is carried out, in one example, under the working condition of 18 ℃/60% environment, the dehumidification amount is higher at high rotating speed, and under the working condition of 27/35%, a higher dehumidification effect is obtained by adopting a low wind level, and the rotating speeds required under different working conditions are different.
According to the embodiment of the invention, the dehumidification assembly comprises a temperature sensor, a humidity sensor, a controller 5 and a fan 8, wherein the temperature sensor and the humidity sensor are both connected with the controller 5, and the controller 5 determines the optimal rotating speed of the fan according to a temperature value transmitted by the temperature sensor and a humidity value transmitted by the humidity sensor so as to regulate and control the fan 8 to operate at the optimal rotating speed.
The environment temperature is detected through the environment temperature sensing bulb 3, the humidity is detected through the humidity sensor, the environment temperature and the humidity are fed back to the controller 5 to be calculated, and the controller 5 returns a signal to the motor in the fan 8 to control the rotating speed after calculation.
The rotating speed of the motor can be regulated by a direct current motor in a mode of pulse width modulation variable frequency speed regulation, tap motor speed regulation or capacitance speed regulation and the like.
According to a further aspect of the present invention, there is provided a dehumidifier comprising a dehumidifying module as described above. As shown in fig. 3 and 4, the dehumidifier has a specific structure including a condenser 1, an evaporator 2, an environmental temperature sensing bulb 3, a humidity sensor detection plate 4, a controller 5, a capillary tube 6, a compressor 7, and a fan 8, and the environmental temperature sensing bulb 3 and the humidity sensor detection plate 4 are disposed on the outer side of the evaporator 2.
The operating principle of the dehumidifier is shown in fig. 4, the condenser 1, the compressor 7, the evaporator 2 and the capillary tube 6 are circularly connected, and the refrigerant circularly flows in the circulating channel. The fan 8 causes the air flow to pass through the environmental temperature sensing bulb 3, the humidity sensor detection plate 4, the evaporator 2, and the condenser 1 in this order.
The controller 5 may be a control device of a conventional dehumidifier, and a function relationship of an optimal rotation speed is preset in the controller, wherein the function relationship of the optimal rotation speed includes an established function relationship between the optimal rotation speed and the temperature value and the humidity value.
In the development stage of the dehumidifier, the optimal rotating speed under the temperature and humidity can be recorded by testing the dehumidification amount of different rotating speeds under different temperatures and humidities, the optimal rotating speed is fitted into a function, and the function is preset into the controller. When the dehumidifier is used, the controller reads the current ambient temperature and humidity and adjusts the rotating speed to the optimal rotating speed, so as to achieve the aim of improving the dehumidification capacity. Generally, there is a one-to-one correspondence relationship between the optimum rotation speed and the ambient temperature and humidity, and the function is not limited to the above function examples, and other function forms are all within the scope of the present patent.
It is easily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
