Example 1
The embodiment provides a dehumidification control method, which is applied to a dehumidifier, and fig. 1 is a structural diagram of the dehumidifier according to an embodiment of the invention, as shown in fig. 1, the dehumidifier includes an evaporator 1, a compressor 2, a condenser 3 and a fan 4, air firstly emits heat through the evaporator, and the evaporation temperature of a compression refrigeration system is determined by assuming that the emitted heat is Q Cold water ,Q Cold water , and the evaporation temperature needs to be at a proper design value (for example, greater than 0 ℃ and less than 15 ℃) and is not suitable to be too low; the air takes away heat through the condenser, and the heat to be taken away is Q Cold water +W Compressor with a compressor body having a rotor with a rotor shaft ,W Compressor with a compressor body having a rotor with a rotor shaft which is the heat emitted by the compressor. Q Cold water +W Compressor with a compressor body having a rotor with a rotor shaft determines the condensing temperature of the compressor refrigeration system, which also needs to be at a suitable design value (e.g., greater than 25 ℃ and less than 65 ℃). Under the condition that the temperature and the humidity of the inlet air are fixed, the air quantity influences the parameters, so that the parameters can be adjusted by adjusting the air quantity of the dehumidifier.
Fig. 2 is a flowchart of a dehumidification control method according to an embodiment of the present disclosure, as shown in fig. 2, the method includes:
s101, acquiring the air inlet temperature of the dehumidifier, and judging whether the air inlet temperature is in a preset interval.
S102, if so, controlling a fan of the dehumidifier to operate according to a preset wind gear.
The air inlet temperature is in a preset interval, for example, the air inlet temperature is more than or equal to 25 ℃ and less than or equal to 36 ℃, which indicates that the current air inlet temperature is moderate, and is not too high or too low, and in order to ensure the dehumidification effect, the air inlet temperature is operated with small air quantity, for example, the fan is switched to 1 gear and then is started to operate, and the air can quickly reach the dew point temperature, so that the dehumidification effect of the unit is ensured.
And S103, if not, adjusting the air quantity of a fan of the dehumidifier according to the evaporation temperature of the evaporator or the condensation temperature of the condenser.
For example, if the inlet air temperature is higher than 36 ℃ or lower than 25 ℃, the evaporation temperature is too low or the condensation temperature is too high, and the air quantity of a fan of the dehumidifier is adjusted according to the evaporation temperature of the evaporator or the condensation temperature of the condenser.
According to the dehumidification control method, when the air inlet temperature is in the preset interval, the fan of the dehumidifier is controlled to operate according to the preset air level, and when the air inlet temperature is not in the preset interval, the air quantity of the fan of the dehumidifier is adjusted according to the evaporation temperature of the evaporator or the condensation temperature of the condenser, so that the air quantity can be adaptively adjusted according to the actual operation condition of the dehumidifier, and the problems that the dehumidifier is frozen or protected under high pressure due to too low air quantity, the operation temperature range is too narrow, and continuous operation cannot be realized are solved; or the air quantity is too high, so that the air can not reach the dew point temperature, and the dehumidifying effect is greatly reduced or even the dehumidifying can not be realized.
When the air inlet temperature is in a preset interval, controlling a fan of the dehumidifier to operate according to a preset wind gear (for example, 1 gear), and comprising: judging the size relation between a preset wind gear and a wind gear set by a user; if the preset wind level is smaller than the wind level set by a user of the dehumidifier, controlling a fan of the dehumidifier to operate according to the preset wind level; and if the preset wind level is greater than or equal to the user-set wind level of the dehumidifier, adjusting the preset wind level to be equal to the user-set wind level. I.e. the fans are preferentially controlled to operate according to the lower wind level.
When the air inlet temperature is lower than the lower limit value of the preset interval, the evaporation temperature may be lower than the lower limit value (for example, 0 ℃) of the evaporation temperature, and the air baffle of the fan needs to be increased, so that the air inlet quantity is increased to increase the evaporation temperature; when the air inlet temperature is higher than the upper limit value of the preset interval, the condensing temperature is possibly higher than the upper limit of the condensing temperature, the fan wind shield is required to be increased, the air inlet quantity is increased, so as to reduce the condensing temperature, therefore, the air quantity of the fan of the dehumidifier is adjusted according to the evaporating temperature of the evaporator or the condensing temperature of the condenser, and the method comprises the following steps: if the intake air temperature is lower than the lower limit value of the preset interval, the air quantity of the fan of the dehumidifier is adjusted according to the evaporation temperature of the evaporator, specifically, the air quantity of the fan of the dehumidifier is adjusted according to the evaporation temperature of the evaporator, and the method comprises the following steps: judging whether the evaporation temperature is smaller than a first preset threshold value or not; if so, controlling the fan gear of the dehumidifier to be gradually increased until the evaporation temperature is greater than or equal to a first preset threshold value.
In the case that the dehumidifier includes a plurality of compressors, the evaporation temperature may be further increased by reducing the number of compressors operated, and thus, controlling the fan gear of the dehumidifier to be gradually increased until the evaporation temperature is greater than or equal to the first preset threshold, the method further includes: judging whether the dehumidifier comprises more than two compressors; if the dehumidifier comprises more than two compressors, gradually reducing the number of the compressors to be operated until the evaporation temperature is greater than or equal to a first preset threshold value, or reducing the number of the compressors to be operated to one; and triggering to adjust the air quantity of a fan of the dehumidifier according to the evaporation temperature of the evaporator after the number of the running compressors is reduced to one.
If the air inlet temperature is higher than the upper limit value of the preset interval, the air quantity of the fan of the dehumidifier is adjusted according to the condensation temperature of the condenser, specifically, the air quantity of the fan of the dehumidifier is adjusted according to the condensation temperature of the condenser, and the method comprises the following steps: judging whether the condensing temperature is larger than a second preset threshold value or not; if yes, the fan gear of the dehumidifier is controlled to be gradually increased until the condensation temperature is smaller than or equal to a second preset threshold value.
The following describes the present invention in detail with reference to a specific example, and the fan of the present invention may be divided into a plurality of gears, such as four gears: gear 1, gear 2, gear 3 and automatic gear. Wherein 3 gear is the highest gear, the rotating speed is the highest, and the air quantity is the largest; the 1 st gear is the lowest gear, the rotation speed is the lowest, and the air quantity is the smallest. The automatic wind gear is automatically selected from 1 gear, 2 gear and 3 gear according to the air inlet temperature.
The air inlet temperature is detected by an air inlet temperature sensing bag.
1. Before the unit is started, the fan operates according to an initial gear.
If the user sets the wind gear to be one of the 1 gear, the 2 gear and the 3 gear, the user sets the wind gear to be the initial wind gear operation.
2. After the initial gear is determined, the automatic gear is adjusted to be an automatic gear, and the gear is adjusted according to the air inlet temperature.
If the air inlet temperature is more than 36 ℃, judging whether the condensing temperature is higher than the condensing temperature upper limit, if so, gradually increasing the gear on the basis of the initial gear until the condensing temperature is less than or equal to the condensing temperature upper limit (namely the second preset threshold).
The condensing temperature sensing bulb is arranged on the condenser heat exchange tube and is used for detecting the corresponding condensing temperature after the condensing temperature fan is started and the system compressor runs for 1 minute. If the inlet air temperature is continuously increased at the moment, when the condensing temperature is detected to be more than the upper limit of the condensing temperature (for example, 65 ℃ C., the unit approaches to a high-pressure protection limiting point and the high-pressure protection is stopped soon), the fan is increased by one gear until the fan is increased to 3 gears. Wherein: the upper limit of the condensing temperature is the highest condensing temperature at which the refrigerating system is allowed to operate, and corresponds to the highest condensing pressure, namely the protection value of the high-voltage switch. For example, the maximum condensing temperature in this example is 65 ℃.
Calculation of condensation temperature: condensing temperature to start the temperature value detected by the condenser bulb of the system when only one compressor of the system is started; when multiple system compressors are all operating, the condensing temperature is the greater of them.
If the temperature of the air inlet is more than or equal to 25 ℃ and less than or equal to 36 ℃, the fan is started to operate after being regulated to 1 gear.
The temperature of the air inlet is more than or equal to 25 ℃ and less than or equal to 36 ℃, which indicates that the current air inlet temperature is moderate, and is not too high or too low, and in order to ensure the dehumidification effect, the air inlet is operated with small air quantity, for example, the fan is switched to 1 gear and then is started to operate, and the air can quickly reach the dew point temperature, so that the dehumidification effect of the unit is ensured. If the user sets the wind level to select a higher wind level, the wind level is also operated according to the 1 level. This control priority is highest.
Because the evaporator temperature is too low and can cause the condensation water to freeze, block the fin air inlet gap, cause the fin air inlet to reduce sharply, further cause the evaporator temperature to reduce, cause vicious circle to aggravate the fin to freeze, cause the unit protection, therefore, if the air inlet temperature is less than 25 ℃, judge whether the evaporator temperature is lower than the evaporation temperature lower limit value (for example, 0 ℃), if yes, step up the gear on the basis of the initial gear until the evaporator temperature is more than or equal to the evaporation temperature lower limit value (namely, the first preset threshold value).
For example, after the fan is started, the corresponding system compressor is operated for 1 minute, and then the evaporation temperature of the corresponding evaporation temperature sensing bulb is continuously detected. If the intake air temperature is continuously reduced at this time, when the evaporating temperature is detected to be less than the lower limit of the evaporating temperature (for example, 0 ℃ C., the condensed water of the evaporator of the unit is easy to freeze, so that the evaporating temperature is quickly reduced and the protection is stopped soon), if a plurality of compressors are all started at this time, a system is immediately closed and operated to increase the evaporating temperature. And continuing to detect until the evaporation temperature is more than or equal to the lower limit of the evaporation temperature. If only one system compressor is left to be turned off, the evaporating temperature is still detected to be less than the lower evaporating temperature limit for 30 seconds continuously; the fan is raised by one gear until it is raised to 3 gear. If the user sets that the wind gear selects 1 gear or 2 gear, the wind gear is also increased to run.
Calculation of the evaporation temperature: when only one system compressor is started, evaporating the temperature to start the temperature value detected by the evaporator temperature sensing bag of the system; when multiple system compressors are all operating, the evaporating temperature is the smaller of them.
FIG. 3 is a schematic diagram of a fan gear corresponding to different air inlet temperatures according to an embodiment of the present invention, as shown in FIG. 3, if the air inlet temperature is 25 ℃ or less and 36 ℃, the fan gear is the lowest, and if the air inlet temperature is > 36 ℃ or less than 25 ℃, the fan gear is correspondingly adjusted.
