Abstract

An air-conditioning control system configured to control air conditioning in a building that includes an air-conditioning room in which an air conditioner is provided and a first air-inflow room into which air flows from the air-conditioning room. The air-conditioning control system includes: a temperature obtaining unit configured to obtain a temperature of the first air-inflow room; and a controller configured to control the air conditioner, based on the temperature obtained by the temperature obtaining unit.

First claim

The invention claimed is:

1. An air-conditioning control system configured to control air conditioning in a building that includes an air-conditioning room in which an air conditioner is provided and a first air-inflow room into which air flows from the air-conditioning room, the air-conditioning control system comprising:
a temperature obtaining unit configured to obtain a temperature of the first air-inflow room; and
a controller which controls the air conditioner, based on a difference between a set temperature that is set for the air-conditioning room and the temperature obtained by the temperature obtaining unit, the set temperature being set in the air conditioner.

2. The air-conditioning control system according to claim 1 , wherein
the air conditioner is settable to a standard set temperature, and a power-saving set temperature in which power consumption of the air conditioner is less than power consumption of the air conditioner in the standard set temperature, and
when the air conditioner is set to the power-saving set temperature, a difference between the standard set temperature and the temperature obtained is greater than a difference between the power-saving set temperature and the temperature obtained, and the difference between the standard set temperature and the temperature obtained exceeds a first temperature difference, the first temperature difference being greater than a difference between the standard set temperature and the power-saving set temperature, the controller is configured to control the air conditioner to change the set temperature from the power-saving set temperature to the standard set temperature.

3. The air-conditioning control system according to claim 2 , wherein
when the air conditioner is set to the standard set temperature, the difference between the standard set temperature and the temperature obtained is greater than the difference between the power-saving set temperature and the temperature obtained, and the difference between the standard set temperature and the temperature obtained falls below a second temperature difference, the second temperature difference being smaller than the first temperature difference, the controller is configured to control the air conditioner to change the set temperature from the standard set temperature to the power-saving set temperature.

4. The air-conditioning control system according to claim 2 , further comprising:
the information obtaining unit configured to obtain information indicating whether a person is present in the air-conditioning room, wherein
only when the information is negative, the controller is configured to further control the air conditioner to set the set temperature to be set to the power-saving set temperature.

5. The air-conditioning control system according to claim 2 , further comprising:
the information obtaining unit configured to obtain information indicating whether present time is within a predetermined period, wherein
only when the information is positive, the controller is configured to further control the air conditioner to set the set temperature to be set to the power-saving set temperature.

6. The air-conditioning control system according to claim 1 , wherein
a first air-discharge fan is provided in the first air-inflow room, the first air-discharge fan being configured to discharge air in the first air-inflow room to outside of the building to cause air from the air-conditioning room to flow into the first air-inflow room, and
the controller is configured to further control a first air-discharge volume, based on the temperature obtained, the first air-discharge volume being a volume of air discharged by the first air-discharge fan per unit time.

7. The air-conditioning control system according to claim 6 , wherein
the building further includes a second air-inflow room into which air flows from the air-conditioning room,
a second air-discharge fan is provided in the second air-inflow room, the second air-discharge fan being configured to discharge air in the second air-inflow room to outside of the building to cause air from the air-conditioning room to flow into the second air-inflow room, and
when the controller controls the first air-discharge volume, the controller is configured to control the first air-discharge volume and a second air-discharge volume to cause a sum of the first air-discharge volume and the second air-discharge volume to remain invariable, the second air-discharge volume being a volume of air discharged by the second air-discharge fan per unit time.

8. An air-conditioning control method performed by an air-conditioning control system configured to control air conditioning in a building that includes an air-conditioning room in which an air conditioner is provided and a first air-inflow room into which air flows from the air-conditioning room, the air-conditioning control method comprising:
obtaining a temperature of the first air-inflow room; and
controlling the air conditioner based on a difference between a set temperature that is set for the air-conditioning room and the temperature obtained, the set temperature being set in the air conditioner.
