For example, the target environment data may include: target temperature, target humidity, target CO for growth conditions of a breeding target₂At least one of the concentration and the target air volume.

In step S406, an air conditioning operation is performed to adjust the actual environmental data to be consistent with the target environmental data according to the comparison result and a predetermined control strategy.

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.

In some embodiments, the step S406 may further include: after the wet film humidifying device is started for the second preset time, judging whether the actual temperature is reduced to the target temperature; and if the actual temperature is reduced to the target temperature, maintaining the on state of the wet film humidifying device, and if the actual temperature is not reduced to the target temperature, controlling the outdoor heat exchanger, the outdoor fan and the indoor heat exchanger to be turned on to perform the cooling mode.

In some embodiments, this step S406 may include: under the condition that the actual air volume is larger than the target air volume, controlling the operation of an internal machine fan to reduce the output fresh air; and under the condition that the actual air volume is smaller than the target air volume, controlling the operation of the internal machine fan to increase the output fresh air.

To this end, a control method for an air conditioning system according to some embodiments of the present disclosure is provided. The control method comprises the following steps: receiving actual environmental data within the farm; comparing the actual environmental data with target environmental data for growth conditions of the breeding target; and performing an air conditioning operation to adjust the actual environmental data to be consistent with the target environmental data according to the comparison result and a predetermined control strategy. 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 step S516, the indoor unit blower and the wet film humidifier are controlled to be turned on in the heating mode so that the fresh air and the indoor return air are mixed and then pass through the indoor heat exchanger, and the outdoor heat exchanger, the outdoor unit blower and the indoor heat exchanger are controlled to be turned on to execute the heating mode.

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 isenthalpic humidification and temperature reduction 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.

Fig. 6 is a schematic diagram illustrating a structure of a controller according to some embodiments of the present disclosure. As shown in fig. 6, the controller may receive a unit 610, a comparison unit 620, and an adjustment control unit 630. The controller is located in an air conditioning unit of an air conditioning system.

The receiving unit 610 is used for receiving actual environmental data in the farm.

The comparison unit 620 is used for comparing the actual environmental data with the target environmental data for the growth conditions of the breeding target.
