DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on embodiments.

(First Embodiment) First, the facts and research results that are the basis of the present embodiment will be described.
At present, the thermal conditions of our living environment are defined based on PMV. PMV (Predicted Mean Vote)
Is based on the thermal equilibrium equation between the human body and the environment, and is based on the thermal factors of the human body, such as the amount of clothing and heat production, and the environmental thermal factors, such as temperature, radiation temperature, air velocity, and water vapor partial pressure. It relates the balance between the required heat production and heat dissipation of the human body to the thermal subjectivity such as "cold" or "hot", and is also called the comfort equation (Reference: ISO7730 Thermal confort by
POFanger McGraw-Hill Book Company 1972). Thermally defined comfort is defined as a state in which heat production and heat radiation of the human body are in equilibrium, and it is assumed that heat production and heat radiation of the human body are stationary.

However, in real life, the balance between heat production and heat radiation of the human body changes due to environmental changes due to movement from the outdoors to the indoors, and the activities of one's own, and the human body usually adapts gradually. For example, during a winter life scene, there is a case where a person moves from a cold outdoor to a heated room. In such a case, the human body adapts to the cold outdoors in the cold. Therefore, in the process of adapting to room temperature after entering the room, the human body is produced against the indoor thermal environment set based on the conventional comfort index PMV. There is a time zone when heat is more than heat dissipation. In such situations, subjectively PM
It feels warmer than the V estimate. At this time, there is room for lowering the set temperature of the environment so as to increase the heat radiation from the human body without impairing the feeling of comfort, leading to reducing the load on the heating equipment in winter and saving energy.

Conversely, in a summer life scene, there is a case where a person moves from a hot outdoors to a room with effective cooling. In such a case, since the human body adapts to the heat in the hot outdoors, in the process of adapting to room temperature after entering the room, the human body is compared with the indoor thermal environment set based on the conventional comfort index PMV. There is a time zone when the heat release exceeds the heat production. In such a situation, it is subjectively felt cooler than the value estimated by PMV. At this time, there is room for raising the set temperature of the environment so as to reduce the heat radiation from the human body without impairing the feeling of comfort, leading to reducing the load on the cooling equipment in summer and saving energy.

That is, it is considered that by detecting that the human body is in the process of thermal adaptation, the load on the cooling and heating equipment can be reduced and energy saving can be realized.
