When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Example 1
The present embodiment provides a method for controlling a start-up of an air conditioner, and fig. 2 is a flowchart of the method, and as shown in fig. 2, the method includes:

wherein, the environmental parameter that relates in this application can include ambient temperature, the refrigerated water leaving water temperature and the ambient humidity of cooling water set.
Step 202: and if the change rate of the environmental parameters is not less than the preset value, controlling the load device to keep in a closed state, and if the change rate of the environmental parameters is less than the preset value, controlling the load device to keep in an open state.
The load device in the present application includes a fan, a water pump, an electromagnetic valve, and the like in an air conditioner. The air conditioner satisfying the turn-on condition means that the turn-on condition for turning on the load device is satisfied under environmental factors such as temperature.
Under the condition that the change rate of the monitored environmental parameters is not less than a preset value, the current environmental temperature is large in change and unstable, and at the moment, even if the monitored temperature value meets the starting condition of the load device, the load device needs to be controlled to be kept in a closed state to prevent the load device from being started and stopped frequently; and under the condition that the change rate of the monitored environmental parameters is smaller than a preset value, the environment is stable at the moment, and the load device can be started, so that the load device is controlled to keep a starting state.
After step 201 is executed, if the load device has been turned on according to the control logic of the air conditioner, in step 202, the turned-on load device is controlled to be turned off if the change rate of the environmental parameter is not less than the preset value, and the turned-on state of the load device is maintained if the change rate of the environmental parameter is less than the preset value; after step 201 is executed, if the load device is not yet turned on according to the control logic of the air conditioner, the load device is kept in a turned-off state under the condition that the change rate of the environmental parameter is not less than the preset value, and the load device is turned on under the condition that the change rate of the environmental parameter is less than the preset value, and is not turned off after being turned on until the turning-on time of the load device is continued to the turning-on delay time of the compressor, the compressor is controlled to be turned on, and then whether the load device is turned off or not is determined according to the monitored environmental temperature.
The operation of controlling the load device to be turned on may specifically include: and controlling the load device to keep the opening state at least for a preset time.
Since the different load devices have different turn-on times, in this embodiment, different minimum turn-on durations may be set for the load devices in advance, so as to avoid the problem that the time parameters need to be modified many times due to the different turn-on times of the load devices. Based on this, controlling the load device to be turned on for the preset time period further may include: determining the minimum starting time corresponding to the load device according to the type of the load device; the load device is controlled to remain on for at least a minimum on-time.
Furthermore, the minimum opening time in the application is not less than the delayed starting time of the compressor, so that the situation that the opening time of the load device reaches the minimum opening time but the compressor is not opened completely can be avoided.
Fig. 3 is a flowchart illustrating another air conditioner on-control method according to the present embodiment, and as shown in fig. 3, the method includes the following processes:
step 305: and judging whether the opening time T of the load device reaches the starting delay time T2 of the compressor, if so, executing step 306, controlling the compressor to be opened, and if not, returning to step 303.
According to the method provided by the embodiment, the on and off of the load device in the air conditioner are controlled based on the change rate of the environmental parameters, so that the problem that the load device is frequently started and stopped due to rapid environmental change is solved, the problem that the compressor cannot be started due to frequent start and stop of the load device is further solved, and the starting efficiency of the air conditioner is improved.
Example 2

the monitoring module 41 is used for monitoring the change rate of the environmental parameters after the air conditioner meets the starting condition;
in this embodiment, the environmental parameters may include an ambient temperature and an ambient humidity.
And a control module 42, configured to control the load device to maintain the off state if the change rate of the environmental parameter monitored by the monitoring module 41 is not less than a preset value, and to control the load device to maintain the on state if the change rate of the environmental parameter is less than the preset value.
Optionally, the control module 42 may further include: the first control unit is used for controlling the load device to keep the opening state at least for a preset time. The first control unit may specifically include: the determining subunit is used for determining the minimum starting duration corresponding to the load device according to the type of the load device; a control subunit for controlling the load device to remain on for at least a minimum on-time. Wherein, the minimum starting time is not less than the delayed starting time of the compressor.
