The present embodiment further provides a control method of an environmental regulation system, as shown in the control flowchart shown in fig. 4, the control method of the present embodiment includes steps S1 to S4, where:
s1, acquiring indoor environment temperature and indoor environment humidity;
in this embodiment, the obtained indoor environment temperature and the indoor environment humidity may be selected as a temperature value and a humidity value at a certain time, and may also be selected as an average dimension value and an average humidity value in a certain time period. And considering the improvement of sampling accuracy and the smoothing of sampling errors, setting a sampling period C1, setting a timer S1 by the control unit for timing, and taking the average value of samples in the period of the temperature sensor and the humidity sensor as control feedback input.
S2, comparing the indoor environment humidity with the optimal humidity value corresponding to the indoor environment temperature, and determining whether humidity regulation is needed according to the comparison result;
in the embodiment, an optimal comfort matching array of temperature and humidity is established in advance in a control system of an air conditioner, any temperature value corresponds to an optimal comfort humidity value, an environment temperature-optimal environment humidity corresponding relation table is formed, and the array in the corresponding relation table supports basic setting and user-defined setting. After the optimal humidity value of the current indoor environment temperature is determined, the optimal humidity value is compared with the current indoor environment humidity value, whether dehumidification is needed or not is determined according to a comparison result, and therefore the problems that due to temperature fluctuation caused by humidification and dehumidification actions, the optimal environment humidity corresponding to the real-time temperature is not in a matching range when the humidity is adjusted to the target humidity value, and the human body feeling comfort is poor are solved.
S3, when it is determined that humidity regulation is needed, correcting the current indoor environment temperature, and taking the optimal environment humidity value corresponding to the corrected environment temperature as the target environment humidity;
in this embodiment, in order to ensure the optimal comfort matching between the load humidity control target and the real-time temperature in consideration of the temperature fluctuation caused by humidity change, as shown in the control flow chart of fig. 4, a temperature compensation parameter Δ T under humidity control is set, and the temperature compensation parameter Δ T is corrected with the current real-time temperature to obtain the final control temperature TControl. Using corrected TControlInquiring and judging in a temperature/humidity comfort array of the self-adaptive control unit, and outputting a final optimal comfort humidity control target value HControlThe target of control of the operation of the humidifying unit and the dehumidifying unit.
And S4, controlling the humidifying unit or the dehumidifying unit to start to regulate and control the indoor environment humidity to the target environment humidity.
The control unit automatically judges and adjusts the output of the load control instruction according to the periodic sampling average value of the humidity and the temperature, sends a real-time control instruction to each load unit of the air conditioning system, correspondingly performs actions such as humidification, dehumidification, maintenance and the like, and achieves the aim of dynamic adjustment.
Further optionally, the step S2 includes S21 to S22, where:
s22, comparing the current indoor environment humidity with the optimal environment humidity;
s21, if the current indoor environment humidity is larger than the optimal environment humidity plus the first set value, judging that the current environment needs to be dehumidified; if the current indoor environment humidity is less than the optimal environment humidity value, namely a first set value, judging that the current environment needs to be humidified; and if the optimal environment humidity value-the first set value is less than or equal to the current indoor environment humidity value and less than or equal to the optimal environment humidity value + the first set value, judging that the humidity regulation and control of the current environment are not needed.
The present embodiment takes into consideration the rationality of the humidity control sensitivity, avoiding repeated start-stop of the load unit. As shown in the control flow chart of fig. 4, humidity adjustment accuracy Δ H is set, and whether humidity fluctuation is within the range of [ - [ Δ H ], + [ Δ H ] is determined for confirming the load unit operation direction (dehumidifying unit operation, humidifying unit operation, current operation maintenance).
Further optionally, the step S3 includes S31 to S33, where:
s31, correcting the current indoor environment temperature, and correcting the indoor environment temperature TCorrectionSatisfies the following conditions: t isCorrectionT1 +/Δ T, where T1 is the current indoor ambient temperature and Δ T is the compensation temperature;
s32, determining the optimal environment humidity corresponding to the corrected indoor environment temperature according to the corresponding relation table of the environment temperature and the optimal environment humidity, and taking the optimal environment humidity as the target environment humidity for humidity regulation and control;
s33, when humidification is needed, controlling the humidification unit to start to humidify the indoor environment, and enabling the humidity value of the indoor environment to reach the set range of the target environment humidity; when dehumidification is needed, the dehumidification unit is controlled to start to dehumidify the indoor environment, so that the humidity value of the indoor environment reaches the set range of the target environment humidity.
In this embodiment, since the change of the indoor humidity may cause temperature fluctuation, if the current room temperature is directly used as the control target, the indoor temperature may be decreased in a certain proportion after humidification. After the humidity adjustment, the humidity of the indoor environment is not optimally matched with the indoor environment temperature due to the change of the indoor environment temperature, but is optimally matched with the indoor environment temperature before the humidity adjustment, so that the humidity overshoot condition occurs, and therefore, the temperature control target is corrected, and the corrected T is usedControlInquiring and judging in a temperature/humidity comfort array of the self-adaptive control unit, and outputting a final optimal comfort humidity control target value HControlThe humidity value of the humidity sensor is used as a control target of the actions of the humidifying unit and the dehumidifying unit, so that the humidity value after adjustment is ensured to be in the optimal humidity range of the current temperature, and the comfort of a user is ensured.
