The invention relates to the field of air conditioners, in particular to an air conditioner control method.

【Background technique】

With the improvement of living standards, people have higher and higher functional requirements for air conditioners, and higher expectations for the comfort brought by their use. Existing household air conditioners or commercial air conditioners generally can only achieve simple temperature adjustment. , and the temperature control often requires manual regulation, which is prone to overcooling or insufficient cooling, and because the humidity of the environment is different, the comfort perceived by the human body is different. Adjust to the comfort zone of the human body. In addition, when the air conditioner reaches the comfort zone, the existing air conditioner still operates for cooling, resulting in waste of resources and overcooling, and cannot meet environmental protection requirements.

Therefore, it is necessary to provide an intelligent, environment-friendly and energy-saving air-conditioning control method based on thermal comfort zone.

【Content of invention】

The object of the present invention is to provide an environment-friendly and energy-saving air-conditioning control method that automatically controls the air-conditioning operation mode based on the thermal comfort zone.

In order to realize the object of the present invention, the following technical solutions are provided:

The air-conditioning control method based on the thermal comfort zone of the present invention adopts a data acquisition module, a judgment module and a control module to control the process, temperature and humidity sensors are installed in the control system, and an indoor temperature and humidity data comparison table is stored in the judgment module. The air-conditioning control method includes: Follow the steps below:

(1) The air conditioner is running, and the data acquisition module automatically collects indoor temperature and humidity data;

(2) The judgment module compares the collected temperature and humidity data with the indoor temperature and humidity data comparison table: judge whether the temperature data belongs to the comfort zone according to the humidity data, if so, go to step (3), otherwise go to step (4);

(3) After performing the air supply or fresh air operation for t1 time, if the shutdown command is received, the program will end the shutdown, otherwise return to step (1);

The system sets the temperature and humidity comfort zone range according to the thermal resistance conditions of different clothes. According to the thermal comfort zone, the relative humidity is divided into grades, and each grade corresponds to a comfortable temperature. In this range of temperature and humidity, most people are satisfied and can reduce the use of air conditioners.

When the temperature and humidity are within the comfort zone, the air conditioner only sends air without cooling; when the temperature and humidity are not within the comfort zone, the humidity is archived first, and if the humidity is too high, the dehumidification operation is performed first; after a period of operation, Then judge whether the temperature and humidity are within the comfort zone.

Divide the temperature and humidity corresponding to the comparison table into three levels. When the air-conditioning control method enters step (4), if it is not within the comfort zone, then judge whether the humidity is in the third level. If so, perform dehumidification operation. After a period of dehumidification operation , and then return to step (1); otherwise, perform cooling operation.

The system sets the temperature and humidity comfort zone range in the comparison table according to the thermal resistance conditions of different clothes.

When the thermal resistance of clothes is 0.5clo, the temperature corresponding to the first gear in the comfort zone is 25-28.5°C, and the relative air humidity is 10-30%; the temperature corresponding to the second gear is 24-28°C, and the relative air humidity is 30-70%; the temperature corresponding to the third gear is 23.5-25.5°C, and the relative air humidity is 70-90%.

When the thermal resistance of clothes is 1.0clo, the temperature corresponding to the first gear in the comfort zone is 20.5-26.5°C, and the relative air humidity is 10-30%; the temperature corresponding to the second gear is 19.5-25.5°C, and the relative air humidity is 30-70%; the temperature corresponding to the third gear is 19-24°C, and the relative air humidity is 70-90%.

When the air conditioner is in cooling operation, it can be carried out according to the set time of the air conditioner, or it can stop cooling after running to the upper limit of the temperature in the comfort zone.

At the end of the program running, you can manually shut down through the remote control, or you can set it according to the system. When the detected indoor temperature and humidity data falls within the range of the comfort zone, it will automatically shut down.

Compared with the prior art, the present invention has the following advantages:

The air conditioner control method of the present invention adopts different control modes for different humidity, and stops the cooling function of the air conditioner within the comfort zone, and only uses air supply or ventilation, thereby achieving the purpose of comfort and energy saving.

The control module controls the operation mode of the air conditioner according to the judgment result of the judgment module.

The system sets the temperature and humidity comfort zone range according to the thermal resistance conditions of different clothes. According to the thermal comfort zone, the relative humidity is divided into grades, and each grade corresponds to a comfortable temperature. In this range of temperature and humidity, most people are satisfied and can reduce the use of air conditioners.

Please refer to Figure 2. The corresponding schematic diagram of the indoor temperature and humidity data comparison table is shown in Figure 2, where the range of the comfort zone is two shaded quadrilaterals: quadrilateral abcd and quadrilateral efgh. The range, the quadrilateral efgh is the comfort zone range corresponding to the thermal resistance of the clothes is 0.5clo, and the small grid shadow ebch in the middle is the overlapping part of the two. The system divides the comfort zones corresponding to the thermal resistance of the two clothes in the comparison table into three levels. The corresponding temperature and humidity comparison table for the comfort zone when the thermal resistance of the clothes is 0.5Clo is divided into three levels as follows:

Table 1 Comfort zone corresponds to temperature and humidity (clothing thermal resistance = 0.5Clo)

Binning Relative humidity(%) Temperature (°C) 1 10～30 25～28.5 2 30～70 24～28 3 70～90 23.5～25.5

The corresponding temperature and humidity comparison table for the comfort zone when the thermal resistance of the clothes is 1.0Clo is as follows:

Table 2 Temperature and humidity corresponding to the comfort zone (clothing thermal resistance = 1.0Clo)

Binning Relative humidity(%) Temperature (°C) 1 10～30 20.5～26.5 2 30～70 19.5～25.5 3 70～90 19～24

As shown in Figure 3, the air conditioning control method based on the thermal comfort zone of the present invention includes the following steps:
