Example 1
This embodiment provides a dehumidification control method applied to a dehumidifier, and fig. 1 is a structural diagram of a dehumidifier according to an embodiment of the present invention, and as shown in fig. 1, the dehumidifier includes an evaporator 1, a compressor 2, a condenser 3, and a fan 4, where air first passes through the evaporator to release heat, and the released heat is assumed to be Q Cold ,Q Cold The evaporation temperature of the compression refrigeration system is determined, and needs to be a proper design value (for example, more than 0 ℃ and less than 15 ℃), and is not suitable to be too low; the air is then passed through a condenser to remove heat, and the heat to be removed is Q Cold +W Compressor ,W Compressor Heat given off by the compressor. Q Cold +W Compressor The condensing temperature of the compressor refrigeration system is determined and also needs to be at a suitable design value (e.g., greater than 25 c, less than 65 c). Under the condition that the temperature and the humidity of the inlet air are constant, the air volume influences the parameters, so that the parameters can be adjusted by adjusting the air volume of the dehumidifier.
Fig. 2 is a flowchart of a dehumidification control method according to an embodiment of the present invention, as shown in fig. 2, the method including:
s101, obtaining the air inlet temperature of the dehumidifier, and judging whether the air inlet temperature is in a preset interval.
And S102, if so, controlling the 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 ℃, the air inlet temperature shows that the current air inlet temperature is moderate, and is not too high or too low, in order to ensure the dehumidification effect, the air inlet temperature is operated with small air volume, for example, the fan is switched to 1 gear and then started to operate, the air can quickly reach the dew point temperature, and the dehumidification effect of the unit is ensured.
S103, if not, adjusting the air volume 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 volume of the 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 inlet air temperature is within a preset interval, the fan of the dehumidifier is controlled to operate according to a preset wind gear, and when the inlet air temperature is not within the preset interval, the air volume 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 volume can be adaptively adjusted according to the actual operation condition of the dehumidifier, and the problems that the dehumidifier is frozen or protected at high pressure due to too low air volume, the operation temperature range is too narrow, and the dehumidifier cannot operate continuously are solved; or the air quantity is too high, so that the air can not reach the dew point temperature, and the dehumidification effect is greatly reduced, even the dehumidification can not be carried out.
When the inlet air temperature is in the preset interval, the fan of the dehumidifier is controlled to operate according to the preset wind gear (for example, 1 gear), including: judging the size relationship between a preset wind shield and a user-set wind shield; if the preset wind gear is smaller than the user set wind gear of the dehumidifier, controlling the fan of the dehumidifier to operate according to the preset wind gear; and if the preset wind gear is larger than or equal to the user set wind gear of the dehumidifier, adjusting the preset wind gear to be equal to the user set wind gear. Namely, the fan is preferentially controlled to operate according to a lower wind gear.
When the inlet air temperature is lower than the lower limit value of the preset interval, the evaporation temperature may be lower than the lower limit value of the evaporation temperature (for example, 0 ℃), and the air level of the fan needs to be increased to increase the inlet air volume so as to increase the evaporation temperature; when the inlet air temperature is higher than the upper limit value of the preset interval, the condensing temperature may be higher than the upper limit value of the condensing temperature, the air level of the fan needs to be increased, and the inlet air volume is increased to reduce the condensing temperature, so that the air volume 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 inlet air temperature is lower than the lower limit value of the preset interval, adjusting the air volume of a fan of the dehumidifier according to the evaporation temperature of an evaporator, specifically, adjusting the air volume of the fan of the dehumidifier according to the evaporation temperature of the evaporator, and the method comprises the following steps: judging whether the evaporation temperature is less than a first preset threshold value or not; if so, controlling the fan gear of the dehumidifier to gradually rise until the evaporation temperature is greater than or equal to a first preset threshold.
Under the condition that the dehumidifier comprises a plurality of compressors, the evaporation temperature can be increased by reducing the number of the running compressors, so that the gear of a fan of the dehumidifier is controlled to be increased step by step until the evaporation temperature is greater than or equal to the first preset threshold, and the method further comprises the following steps: judging whether the dehumidifier comprises more than two compressors or not; if the dehumidifier comprises more than two compressors, gradually reducing the number of the running compressors until the evaporation temperature is greater than or equal to a first preset threshold value or the number of the running compressors is reduced to one; and after the number of the running compressors is reduced to one, triggering to adjust the air volume of a fan of the dehumidifier according to the evaporation temperature of the evaporator.
If the inlet air temperature is higher than the upper limit value of the preset interval, the air volume of a fan of the dehumidifier is adjusted according to the condensation temperature of the condenser, specifically, the air volume 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 condensation temperature is greater than a second preset threshold value or not; if so, controlling the fan gear of the dehumidifier to gradually rise until the evaporation temperature is less than or equal to a second preset threshold.
The present invention is described in detail below with reference to a specific example, and the fan of the present invention can be divided into a plurality of gears, for example, four gears: 1 st, 2 nd, 3 rd and automatic gears. Wherein, the 3 gear is the highest gear, the rotating speed is highest, and the air volume is largest; the 1 gear is the lowest gear, the rotating speed is lowest, and the air volume is minimum. The automatic wind gear is automatically selected from 1 gear, 2 gears and 3 gears according to the temperature of the inlet wind.
The temperature of the inlet air is detected by the inlet air temperature sensing bulb.
1. Before the unit starts, the fan operates according to an initial gear.
And if the user-set gear is selected to be one of the gears 1, 2 and 3, the user sets the gear to be the initial gear for operation.
2. And after the initial gear is determined, adjusting the gear to be an automatic gear according to the air inlet temperature.
If the inlet air temperature is higher than 36 ℃, judging whether the condensation temperature is higher than the upper limit of the condensation temperature, if so, gradually increasing the gear on the basis of the initial gear until the condensation temperature is less than or equal to the upper limit of the condensation temperature (namely the second preset threshold).
The condensation temperature thermal bulb is installed on a heat exchange tube of the condenser and used for continuously detecting the corresponding condensation temperature after a system compressor runs for 1 minute after a fan for detecting the condensation temperature is started. If the inlet air temperature is continuously increased, when the condensation temperature is detected to be higher than the upper limit of the condensation temperature (for example, 65 ℃ C.) for 30s continuously, the unit approaches a high-voltage protection limiting point, and the high-voltage protection is stopped quickly), the fan is increased by one gear until the gear is increased to 3. Wherein: the upper limit of the condensing temperature is the highest condensing temperature 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 of this embodiment is 65 ℃.
Calculation of the condensation temperature: when only one system compressor is started, the condensing temperature is the temperature value detected by a condenser temperature sensing bulb of the starting system; when a plurality of system compressors are all operated, the condensing temperature is the greater of them.
If the air inlet temperature is more than or equal to 25 ℃ and less than or equal to 36 ℃, the fan is started to operate after being adjusted to 1 gear.
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, in order to ensure the dehumidification effect, the low air volume operation is adopted, for example, the fan is switched to 1 gear and then is started, the air can quickly reach the dew point temperature, and the dehumidification effect of the unit is ensured. If the user sets the gear and selects a higher gear, the system also operates according to the gear 1. This control has the highest priority.
Because the evaporator temperature is too low, condensed water may be frozen, and air inlet gaps of fins are blocked, so that the air inlet quantity of the fins is rapidly reduced, the temperature of the evaporator is further reduced, vicious circle is caused, the freezing of the fins is aggravated, and the unit is protected, therefore, if the air inlet temperature is stopped to be less than 25 ℃, whether the temperature of the evaporator is lower than the lower limit value of the evaporation temperature (for example, 0 ℃) is judged, and if the temperature of the evaporator is lower than 25 ℃, the gear is gradually increased on the basis of the initial gear until the temperature of the evaporator is greater than or equal to the lower limit value of the evaporation temperature (namely, the first preset threshold).
For example, after the fan is started and the corresponding system compressor runs for 1 minute, the evaporation temperature of the corresponding evaporation temperature bulb is continuously detected. If the inlet air temperature is continuously reduced at the moment, when the evaporation temperature is detected to be less than the lower limit of the evaporation temperature (for example, 0 ℃ is detected for 30s continuously, condensed water of the evaporator of the unit is easy to freeze, so that the evaporation temperature is rapidly reduced, and the protection machine is shut down quickly), and if a plurality of compressors are all started at the moment, one system is immediately shut down to improve the evaporation temperature. And continuously detecting until the evaporation temperature is more than or equal to the lower limit of the evaporation temperature. If only one system compressor is closed, the evaporation temperature is continuously detected to be less than the lower limit of the evaporation temperature for 30 s; the fan is raised to first gear until the fan is raised to 3 gears. If the user sets the gear to select 1 gear or 2 gears, the gear is also raised to operate.
Calculation of evaporation temperature: when only one system compressor is started, evaporating the temperature according to the temperature value detected by an evaporator temperature sensing bulb of the starting system; when a plurality of system compressors are all operated, the evaporation temperature is the smaller of them.
FIG. 3 is a schematic diagram of corresponding fan gears at different inlet air temperatures according to an embodiment of the present invention, as shown in FIG. 3, if the inlet air temperature is greater than or equal to 25 ℃ and less than or equal to 36 ℃, the fan gear is the lowest, and if the inlet air temperature is greater than 36 ℃ or the inlet air temperature is less than 25 ℃, the fan gear is correspondingly increased.
