Abstract

An air conditioning control device controls an air conditioning apparatus capable of changing an air environment of a target space. The air conditioning control device includes a first information grasping unit and a control unit. The first information grasping unit grasps a predetermined comfort-related value relating to comfort of a subject. The control unit controls the air conditioning apparatus so as to satisfy a predetermined discomfort condition based on the comfort-related value grasped by the first information grasping unit. An air conditioning apparatus includes the air conditioning control device.

First claim

What is claimed is:

1. An air conditioning control device for controlling an air conditioning apparatus capable of changing an air environment of a target space, the air conditioning control device comprising:
a first sensor sensing a value used for calculating a PMV, the PMV being a thermal environment evaluation index;
a second sensor sending a value used for calculating an arousal level of the subject; and
an electronic controller including a CPU,
the CPU being configured to calculate the PMV of a subject based on the value sensed by the first sensor,
the CPU being further configured to calculate the arousal level of the subject based on the value sensed by the second sensor,
the CPU being further configured to execute a normal control mode in which the air conditioning apparatus is controlled so that a set temperature condition of the target space is satisfied,
the CPU being further configured to start an arousal control mode in a case in which the arousal level of the subject is below a predetermined value while the normal control mode is being executed, and
the CPU being further configured to execute the arousal control mode in which the air conditioning apparatus is controlled, so that an absolute value of the PMV of the subject increases by more than 1 from a current absolute value of a current PMV by changing the PMV of the subject from the current PMV in a direction away from 0.

2. The air conditioning control device according to claim 1 , wherein
the PMV is grasped from at least a temperature and a humidity in the target space.

3. The air conditioning control device according to claim 1 , wherein
the CPU is further configured to continue control of the air conditioning apparatus for 4 minutes or more to increase the absolute value of the MEV of the subject so that the absolute value of the PMV of the subject is larger than the current value by 2 or more.

4. The air conditioning control device according to claim 1 , wherein
the CPU is further configured to continue control for at least 1 minute or more, the control being based on the PMV.

5. The air conditioning control device according to claim 4 , wherein
the CPU is further configured to set a duration of control to 30 minutes or less, the control being based on the MIN.

6. The air conditioning control device according to claim 1 , wherein
the CPU is further configured to set a duration of control to 30 minutes or less, the control being based on the PMV.

7. An air conditioning apparatus including the air conditioning control device according to claim 1 .
