average temperature of chicken coop center (sigma)i＝24Actual temperature of the temperature sensor)/24. (1)

The plurality of humidity sensors 112 are used to detect actual humidity at different locations. The group control device 120 is configured to obtain an average value of the actual humidity according to the actual humidity at different locations, and send the average value of the actual humidity to the air conditioning unit 130.
Taking an example of 24 humidity sensors arranged at the center of a coop in a farm, the average humidity (i.e. the average value of the actual humidity) at the center of the coop is calculated as follows:
average humidity (sigma) of coop centeri＝24Actual wetness of the wetness sensorDegree)/24. (2)
As another example, the sensor group 110 may include multiple COs2Concentration sensor 113 of the plurality of CO2The concentration sensors 113 are respectively located at different positions in the farm. The multiple CO2The concentration sensor 113 is used to detect actual CO at different locations2And (4) concentration.

average concentration (∑) of coop CO2i＝6Actual concentration of CO2 sensor)/6. (3)
For another example, the sensor group 110 includes a plurality of air volume sensors 114, and the plurality of air volume sensors 114 are located at different positions in the farm. The plurality of air volume sensors 114 are used to detect actual air volumes at different positions. The cluster control device 120 is configured to calculate an average value of actual air volumes according to actual air volumes at different positions, and send the average value of the actual air volumes to the air conditioning unit 130.

Of course, the scope of the present disclosure is not limited thereto.
In the above embodiment, under the condition that the temperature cannot be reduced to the target temperature through the combined action of the fresh air and the humidification, the temperature is further reduced in a mode of executing a refrigeration mode by the air conditioning unit, so that the purpose of reducing the temperature to the target temperature is achieved.
In the above embodiment, the controller may exercise the temperature priority control.

In some embodiments, this step S406 may include: controlling the inner fan to output fresh air under the condition that the actual temperature is higher than the target temperature; after outputting the fresh air for the first preset time, judging whether the actual temperature is reduced to the target temperature; and if the actual temperature is reduced to the target temperature, controlling the inner fan to keep outputting fresh air, and if the actual temperature is not reduced to the target temperature, controlling the wet film humidifying device to be started.

To this end, a control method for an air conditioning system according to some embodiments of the present disclosure is provided.

Thus, the air in the farm is adjusted, and the actual environmental conditions in the farm can meet the growth conditions of the breeding targets.
Fig. 5 is a flowchart illustrating a control method for an air conditioning system according to further embodiments of the present disclosure. As shown in fig. 5, the control method may include steps S502 to S516.
In step S502, actual environmental data within the farm is received.
For example, the group control device collects the actual temperature, the actual humidity and the actual CO in the farm through the sensor group2And actual environment data such as concentration and actual air volume are sent to a controller of the air conditioning unit, and the controller receives the actual environment data.
In step S504, the actual environmental data and the target environmental data for the growth conditions of the breeding target are compared. For example, the target environment data may include: a group of demand parameters for controlling the growth temperature and fresh air volume of the chickens in the chicken farm day by day according to the design data.
In step S506, the indoor unit fan is controlled to output fresh air when the actual temperature is higher than the target temperature. Namely, the controller controls the inner fan to supply fresh air and cool.
In step S508, after the fresh air is output for the first predetermined time, it is determined whether the actual temperature is reduced to the target temperature. If so, the process returns to the step S506, namely the fresh air output by the inner fan is kept; otherwise the process proceeds to step S510.
In step S510, the wet film humidifying device is controlled to be turned on. At this time, the controller controls to start only the inner fan and not the outer fan, and adopts the wet film humidifying device to cool down, and the fresh air is processed to the designed air supply state point (for example, the dry bulb temperature is 23.5 ℃, and the relative humidity RH is 80%).
In step S512, after the wet film humidifying device is turned on for a second predetermined time, it is determined whether the actual temperature is decreased to the target temperature. If so, the process returns to step S510, i.e., the on state of the wet film humidifying device is maintained; otherwise the process proceeds to step S514.
In step S514, the outdoor heat exchanger, the outdoor unit fan, and the indoor heat exchanger are controlled to be turned on to perform the cooling mode. Namely, the controller controls the refrigeration mode of the unit to be started to cool.

In the heating condition, fresh air and indoor return air are directly mixed and then cooled or heated in the circulating unit, and the cooling is realized by carrying out equal enthalpy humidification and temperature reduction (but the temperature cannot be reduced) through a wet film humidifying device until the temperature and the humidity meet the standards set by the automatic controller. The air conditioning unit can be of a heat pump type, can switch a refrigerating mode and a heating mode, and heats mixed air through an indoor heat exchanger during heating. Because the plant (for example chicken coop) requires constant temperature and humidity, the temperature is promoted through the operation of unit, but probably can not change humidity, consequently, humidity can be through the equal enthalpy humidification cooling of wet film humidification device (but the temperature can not drop very low). The two are regulated and controlled in a balanced manner to reach a balanced target value.
To this end, there are provided control methods for an air conditioning system according to other embodiments of the present disclosure. By the control method, the actual temperature in the farm can be regulated, so that the temperature in the farm meets the requirement, the periodical independent control of the temperature and the humidity is realized, and the power saving effect can be realized by the control strategy.
