The storage unit 101c has a device selected from ROM, RAM, EEPROM, or the like.

The storage unit 101c stores a set temperature and humidity set for each space E1, a floor area table, and an air volume table.

The storage unit 101c further includes a power consumption table showing the relationship between the temperature difference and the predicted power consumption when the air conditioning is controlled by taking in the outside air and the predicted power consumption when the air conditioning is controlled without taking in the outside air. (see Table 4) are stored for each space E1. Here, the temperature difference is the difference value between the room temperature and the outside air temperature of the corresponding space E1. Also, the power consumption when the outside air is taken in and the power consumption when the outside air is not taken in are the sums of the power consumption of the corresponding space E1 and the power consumption of the air conditioner 20 .

For example, when the temperature difference T is 2° C. or more and less than 5° C., and air conditioning is controlled by taking in outside air, the predicted power consumption is “a1” kWh. When the temperature difference T is 2° C. or more and less than 5° C. and air conditioning is controlled without taking in the outside air, the predicted power consumption is “a2” kWh. When the temperature difference T is 5° C. or more and air conditioning is controlled by taking in the outside air, the predicted power consumption is “a3” kWh. When the temperature difference T is 5° C. or more and air conditioning control is performed without taking outside air, the predicted power consumption is “a4” kWh.

Calculate the power consumption and the power consumption when outside air is not taken in.

For example, the storage processing unit 107 classifies the corresponding history data of the space E11 into cases in which outside air is taken in and cases in which outside air is not taken in, based on the temperature difference and the control information associated with each. The storage processing unit 107 calculates the average value of the power consumption represented by the history data of the space E11 for each of the four classified groups.

The storage processing unit 107 further classifies the history data of the air conditioning equipment 20 into cases in which outside air is taken in and cases in which outside air is not taken in, based on the control information associated with each.

The power consumption "a1" is calculated by adding the average value of the power consumption. The storage processing unit 107 adds the power consumption of the air conditioner 20 calculated when the outside air is taken in to the average value of the power consumption of the space E11 calculated when the temperature difference T is 5° C. or more and the outside air is taken. is added to calculate the power consumption "a3". The storage processing unit 107 determines that the temperature difference T is 2° C. or more and less than 5° C., and the average value of the power consumption of the space E11 calculated assuming that the outside air is not taken in is added to the air conditioner calculated assuming that the outside air is not taken in. 20 is added to calculate the power consumption "a2". The storage processing unit 107 adds the power consumption of the air conditioner 20 calculated when outside air is not taken in to the average value of the power consumption of the space E11 calculated when the temperature difference T is 5° C. or more and no outside air is taken in. The power consumption "a4" is calculated by adding the average value of the power consumption.

Note that the storage processing unit 107 may obtain the power consumption amounts “a1”, “a2”, “a3”, and “a4” by a test operation when the history data does not exist. For example, the storage processing unit 107 causes the air-conditioning control system 2C to perform a test operation for a certain period of time, and uses the obtained power consumption amount for each space E1 and the power consumption amount of the air conditioner 20 to obtain data similar to the case of using history data. The power consumption amounts a1 to a4 may be obtained by a calculation method.

The control method includes an external environment acquisition step, an internal environment acquisition step, a comparison step, and a device control step. The external environment step acquires the outdoor temperature, which is the outdoor temperature of the facility (5). The internal environment acquisition step acquires the room temperature, which is the temperature of each of the spaces (E1), for each of the spaces (E1). In the comparison step, for each of a plurality of set temperatures set for each of the plurality of spaces (E1), the set temperature and the outside air temperature are compared. In the device control step, for a control target space for which a comparison result satisfies a predetermined condition among the plurality of spaces (E1), based on space information related to the control target space, the outside temperature, and the indoor temperature in the control target space A ventilation device provided in the control target space among the plurality of ventilation devices is operated to take outside air into the control target space.

According to this control method, it is possible to improve the air conditioning efficiency of the controlled space.

A program of the fifteenth aspect is a program for causing a computer to execute the control method of the fourteenth aspect.

According to this program, the air conditioning efficiency of the controlled space can be improved.
