As shown in FIG. 1, a method for controlling a unit is provided, which may include the following steps 101-102:

Step 101: Obtain temperature and humidity parameters during the operation of the unit;

The temperature and humidity parameters may include but are not limited to: indoor target temperature, indoor target humidity, indoor actual temperature, indoor actual humidity, and indoor actual wind speed.

Step 102: Adjust the operating parameters of the unit according to the temperature and humidity parameters to control the unit to enter the comfort control mode.

That is, during the operation of the unit, the unit is adjusted through the temperature and humidity parameters, so that the unit can enter the comfort mode. The above methods solve the problems of the long operation time of the existing unit and the poor user experience. The technical effect of effectively improving the comfort and user experience of the unit has been achieved.

In the above step 102, adjusting the operating parameters of the unit according to the temperature and humidity parameters to control the unit to enter the comfort control mode may include:

S1: During the unit process, adjust the load output of the unit according to the temperature and humidity parameters;

S2: When the load output of the unit remains unchanged for a preset time threshold, control the unit to enter the comfort control mode;

S3: After entering the comfort control mode, the operating parameters of the unit are adjusted according to the temperature and humidity parameter values.

That is, you can first control the unit to enter the comfort control mode by controlling the load output of the unit, and then adjust the operating parameters based on the comfort control mode.

The end of the main unit connection of the multi-unit cold and hot water unit is water heat exchange. There is a problem of control delay, which leads to insufficient user comfort. This problem can be improved by S11-S14.

In some embodiments, adjusting the load output of the unit according to the temperature and humidity parameters includes:

S11: Obtain the indoor temperature deviation according to the indoor target temperature and the indoor actual temperature;

S12: Obtain the indoor humidity deviation according to the indoor target humidity and the indoor actual humidity;

S13: Obtain the indoor temperature and humidity deviation according to the indoor actual temperature and the indoor actual humidity;

S14: Adjust the load output of the unit according to the comparison result of the cumulative sum of the indoor temperature deviation, the indoor humidity deviation, and the indoor temperature and humidity deviation with a preset threshold. Therefore, it is beneficial to reach the indoor target temperature and indoor target humidity faster.

For example, the indoor target temperature Tb, the indoor target humidity Ta, the indoor actual temperature Th, the indoor actual humidity Ts, and the indoor actual wind speed V are detected in real time. Real-time calculation of indoor temperature deviation ΔT1 = Th-Tb, indoor humidity deviation ΔT2 = Ts-Ta, indoor temperature and humidity deviation ΔT3 = Th-Ts; in the present disclosure, the temperature is, for example, dry bulb temperature, and the humidity is, for example, wet bulb temperature, etc. Information reflecting humidity.

Run after booting:

When ΔT1 + ΔT2 + ΔT3≥2 ℃ is detected every 5s, the unit load F1 increases by ΔF, that is, F = F1 + ΔF;

The unit load F1 will not change when -2≤ΔT1 + ΔT2 + ΔT3≤2 ℃ is monitored every 5s;

When ΔT1 + ΔT2 + ΔT3≤-2 ℃ is monitored every 5s, the unit load F1 decreases by ΔF, that is, F = F1-ΔF;

In some embodiments, ΔF = | ΔT1 * α + ΔT2 * β + ΔT3 * γ |, where α is the temperature difference correction coefficient, β is the temperature difference correction coefficient, and γ is the temperature change rate correction coefficient.

When the unit load remains unchanged for 60s, you can enter the comfort control mode, and the interactive display panel prompts the user to indicate this information, indicating that the comfort mode can be used.

In some embodiments, adjusting the operating parameters of the unit according to the temperature and humidity parameter values may include:

S31: Obtain an indoor temperature deviation according to the indoor target temperature and the indoor actual temperature;

S34: Adjust the load output of the unit according to the cumulative sum of the indoor temperature deviation and the indoor humidity deviation;

S35: Adjust the fan frequency according to the indoor humidity deviation;

S36: Adjust the water valve opening according to the indoor temperature and humidity deviation. Therefore, on the basis of step S14, through steps S34 to S36, fine adjustment is performed near the indoor target temperature and indoor target humidity.

For example: when ΔT1 + ΔT2≥0 ℃ is detected every 5s, the unit load F1 increases by ΔF1, that is, F = F1 + ΔF1;

When ΔT1 + ΔT2 <0 ℃ is detected every 5s, the unit load F1 decreases by ΔF1, that is, F = F1-ΔF1;

Among them, ΔF1 = | Tc * γ |, where γ is the temperature change rate correction coefficient.

When ΔT2≥1 ℃ is detected every 5s, the fan frequency F2 increases by ΔF2, that is, F = F2 + ΔF2;

When -1 <ΔT2 <1 ℃ is detected every 5s, the fan frequency F2 decreases by ΔF2, that is, F = F2-ΔF2;

When ΔT2≤-1 ℃ is detected every 5s, the fan frequency F2 decreases by ΔF2, that is, F = F2-ΔF2;

Among them, ΔF2 = | ΔT2 * β |, where β is the temperature change rate correction coefficient.

When ΔT3 ≥ 0 ℃ is detected every 5s, the water valve opening F3 increases by ΔF3 opening, that is, F = F3 + ΔF3;

When ΔT3 <0 ℃ is detected every 5s, the water valve opening degree F3 decreases by ΔF3 opening degree, namely F = F3-ΔF3;

Among them, note: ΔF3 = | ΔT3 * δ |, where δ is the temperature change rate correction coefficient.

The unit load F1 will not change when -2≤ΔT1 + ΔT2 + ΔT3≤2 ℃ is monitored every 5s;

When ΔT1 + ΔT2 + ΔT3≤-2 ℃ is monitored every 5s, the unit load F1 decreases by ΔF, that is, F = F-ΔF;

Where ΔF1 = | ΔT1 * α + ΔT2 * β + ΔT3 * γ |, where α is the temperature difference correction coefficient, β is the temperature difference correction coefficient, and γ is the temperature change rate correction coefficient.

When the unit load remains unchanged for 60s, you can enter the comfort control mode, and the interactive display panel prompts the user to indicate this information, indicating that the comfort mode can be used.

Specifically, the comfort adjustment can be:

When ΔT1 + ΔT2≥0 ℃ is detected every 5s, the unit load F1 increases by ΔF1, namely F = F1 + ΔF1;

When ΔT1 + ΔT2 <0 ℃ is detected every 5s, the unit load F1 decreases by ΔF1, that is, F = F1-ΔF1;

Among them, ΔF1 = | Tc * γ |, where γ is the temperature change rate correction coefficient.

When ΔT2≥1 ℃ is detected every 5s, the fan frequency F2 increases by ΔF2, that is, F = F2 + ΔF2;

When -1 <ΔT2 <1 ℃ is detected every 5s, the fan frequency F2 decreases by ΔF2, that is, F = F2-ΔF2;

When ΔT2≤-1 ℃ is detected every 5s, the fan frequency F2 decreases by ΔF2, that is, F = F2-ΔF2;

Among them, ΔF2 = | ΔT2 * β |, where β is the temperature change rate correction coefficient.

When ΔT3 ≥ 0 ℃ is detected every 5s, the water valve opening F3 increases by ΔF3 opening, that is, F = F3 + ΔF3;

When ΔT3 <0 ℃ is detected every 5s, the water valve opening degree F3 decreases by ΔF3 opening degree, namely F = F3-ΔF3;

Among them, note: ΔF3 = | ΔT3 * δ |, where δ is the temperature change rate correction coefficient.
