The temperature distribution of a vertical plane wall that is in contact with a fluid such as air will be explained. As shown in the figure, the room temperature is tl, the outside temperature is t2, and the surface temperature of the inner wall on the indoor side is θ.
Assuming that the surface temperature of the wall on the outdoor side is 62, the wall is divided into three regions, and the thickness and thermal conductivity of the first wall region from the left in the figure are δ1 and λ1, respectively, and the second wall region is The thickness and thermal conductivity of the wall region of δ2 and λ2., respectively. The thickness and thermal conductivity of the third wall region are δ3 and λ3, respectively, and the heat transfer resistances due to indoor and outdoor free convection are rsl and rs2, respectively.
and the thermal conduction resistances of the first, second and third regions of the wall are rcl rC2 and rC3, respectively.
Let R be the overall heat flow resistance between the indoor and outdoor areas, θ′ be the temperature at the interface between the first and second regions of the wall, and let θ′ be the temperature at the interface between the first and second regions of the wall. The temperature of the boundary surface is θ

Detection of the indoor temperature in a double-type air conditioner has conventionally been carried out by detecting the temperature of the air sucked into the indoor unit. Since the air is sucked in before it reaches the room, it is not possible to accurately detect the room temperature. Therefore, by providing a wall temperature detection section capable of detecting the surface temperature of the wall and the temperature of the boundary surface, as used in the above-mentioned duct type air conditioner, it becomes possible to accurately detect the room temperature.
