The air conditioner control method provided by the invention comprises the following steps:
human detection device detects indoor personnel condition, and when detecting indoor someone, it is indoor for someone state promptly, timing device begins the timing, and simultaneously, air conditioning system opens to improve the operation of target load, in order to reach the purpose of quick adjustment room temperature. And after the air conditioning system increases the target load and operates for the first preset time, reducing the operation load, and entering a conventional operation mode, namely, adjusting the operation load according to the indoor temperature change by the air conditioning system and keeping the indoor temperature. Avoid the discomfort of indoor personnel caused by long-time high-load operation. Further, the first predetermined time is 5 to 10 minutes.
Or after the indoor temperature reaches the set temperature, the operation load is reduced, the excessive regulation of the indoor temperature is avoided, and the indoor personnel feel uncomfortable. Or after the human body detection device detects that the indoor state is the manned state for a certain time, the air conditioning system is started again, and frequent starting and stopping of the air conditioning system caused by temporary personnel entering the room are prevented. The human body detection device detects that a person is in a room, the timing device starts timing, when the timing of the timing device reaches a second preset time, the air conditioning system is started, the target load operation is improved, meanwhile, the timing device starts timing the operation time of the air conditioning system, when the operation time of the air conditioning system reaches a first preset time, the operation load is reduced, the normal operation mode is entered, namely, the air conditioning system adjusts the operation load according to the indoor temperature change, and the phenomenon that the person in the room feels uncomfortable due to long-time high-load operation is avoided. Or after the indoor temperature reaches the set temperature, the operation load is reduced, the excessive regulation of the indoor temperature is avoided, and the indoor personnel feel uncomfortable. Further, the second predetermined time is 3 to 5 minutes.
Further, increasing the target load means: for example, when the load when the target indoor temperature is set to 25 degrees is set as the target load when the air conditioning system is cooling, and the indoor temperature is high immediately after a person enters the room, the air conditioning system is first operated at a target temperature lower than 25 degrees in order to quickly bring the room to 25 degrees, and the load of the air conditioning system is higher than the load when the target temperature is 25 degrees. When the indoor temperature reaches or approaches 25 degrees, the target temperature is adjusted to 25 degrees again, and the operation load of the air conditioner is reduced. When the air conditioning system is a central air conditioner, the target load is increased by increasing the air supply amount; when the air conditioning system is a household air conditioner, the target load is increased by increasing the power of the compressor and the air supply amount. Similarly, when the air conditioning system heats, the target load is provided by increasing the target temperature, and the control principle is the same as that of the air conditioning system during cooling.
After the air conditioning system is started, the human body detection device continues to detect the indoor personnel distribution area and the quantity of personnel in each area. And then controlling the air outlet of the air conditioning system in the region with the persons to be opened, and controlling the air outlet of the region without the persons to be closed, so as to supply air to the regions with the persons. And the air supply amount is controlled according to the number of personnel in each area, namely the opening of the air outlet is controlled. The opening degree of the air outlet of the area with fewer people is smaller, air is supplied by smaller air supply amount, and the opening degree of the air outlet of the area with more people is larger, and air is supplied by larger air supply amount. When the personnel distribution area changes or the quantity of personnel in any area changes, the air outlet direction or the air outlet quantity is controlled to be adjusted by controlling the opening and closing state or the opening degree of the air outlet of the air conditioning system. So as to ensure that the comfort of personnel in each area is better.
When the human body detection device detects that all indoor people leave, namely the indoor space is in an unmanned state, the timing device starts timing, and when the timing reaches a third preset time, the controller controls to reduce the target load of the air conditioning system, preferably controls the air conditioning system to operate at the minimum load, so that the indoor space is kept at a certain temperature. When the air conditioning system runs at the minimum load but the running time does not reach the fourth preset time, a person enters the room, and after the indoor time of the person reaches the second preset time, the air conditioning system increases the running load and enters a conventional running mode. And when the indoor unmanned state time reaches the fourth preset time, the air conditioning system is closed. Further, the third preset time is 10-15 minutes, and the fourth preset time is 15-20 minutes.
Preferably, when the air conditioning system is a central air conditioner, the blower of the central air conditioning system is turned off after the indoor unmanned state reaches the fourth predetermined time. And when the air conditioning system is a household air conditioner and the indoor unmanned state reaches the fourth preset state, closing the indoor unit and the outdoor unit.
Furthermore, the air conditioning system also comprises a manual operation panel, and when the regulation of the control method of the air conditioning system cannot meet the requirements of indoor personnel, the air conditioning system can be operated through the manual operation panel. Temperature adjusting parameters are input into the manual control panel to control the working state of the air conditioning system so as to meet the requirements of indoor personnel.
Further, the air conditioning system includes an automatic mode and a manual mode, when the air conditioning system is in the automatic mode, the air conditioning system operates according to the aforementioned control method, and automatically adjusts the operating parameters (such as the target temperature, the air supply amount, and the like) of the air conditioning system, and when the air conditioning system is in the manual mode, the air conditioning system operates according to default operating parameters when being powered on, and when the operating parameters need to be adjusted, the air conditioning system needs to be manually operated by a user.
The air conditioning system control method and the air conditioning system control system can realize intelligent regulation and control of the air conditioning operation condition by different numbers of people, room entering time and the current room temperature, detect the number of people in indoor personnel distribution areas and all areas through the human body detection device, increase the air supply volume in areas with more people, reduce the air supply volume in areas with less people and regulate the temperature comfort level to the maximum extent; when the air conditioner enters a room, the air conditioner operates at a large load, the intelligent control operation state is carried out and kept after a certain time, the minimum load operation is carried out after a certain time after people leave, and the air conditioner is closed after the time is exceeded; the customer can also start a manual operation mode to select a mode required by the customer for regulation and control.
