Fluororesins such as ethylene resin (PTFE) and titanium oxide (Tf)
It is formed from pigments such as Oz). The radiant heat transfer coefficient of the paint layer (4) is made to substantially match the radiant heat transfer coefficient of the human body, etc., so that the radiant temperature of the human body can be detected with high accuracy. That is, the spectral reflectance of skin and clothing is high in the visible light and near-infrared light regions, and close to zero in the infrared light region, so the paint layer (4) is made to correspond to this spectral reflectance, for example. We aim to obtain spectral radiation characteristics similar to those of the actual human body, such as skin color or cream color. what if,
If the paint layer (4) is black paint, the reflectance in the visible light and near-infrared light regions will be close to zero, and it will absorb more heat from high-temperature heat sources such as sunlight than the actual human body, resulting in overestimation. I will do it. Therefore, a paint layer (4) of one color or the like as described above is applied.

なるように構成されている。On the other hand, the front air heat insulating layer (9) has a radiant heat absorption plate (3).
) is insulated from the outside with an air layer, the thickness of which is set to a thickness that prevents natural convection. In other words, as shown in Figure 5, when two flat plates are installed in parallel, the vertical axis is the distance between the plates, and the horizontal axis is the temperature difference between the plates, and natural convection occurs due to the temperature difference. The distance between the plates is as shown in the solid line. When the distance between the plates becomes larger than this solid line Δ, natural convection occurs and heat transfer due to this convection increases. Therefore, if the thickness of the front air insulation layer (9) in this embodiment is increased, the insulation effect will be greater (although if it is made larger than the actual mA, natural convection will occur within the insulation layer (9) and the convection will increase). Since convective heat transfer occurs in addition to heat, the structure is such that most of the heat transferred to the absorption plate (3) of 5 nV to 1 Qmm becomes radiant heat transmitted through the transmission film (8).

が制御されることになる。First, this radiant temperature detector (1) is installed in an indoor unit of an air conditioner, and radiant heat emitted from walls, floors, etc. is transmitted to the radiant heat transmission film (8) as heat rays. Since the permeable membrane (8) is made of polyethylene, a silicon substrate, etc., the radiant heat is reliably transmitted and transmitted to the paint layer (4) via the air insulation layer (9). After radiant heat is absorbed in this paint layer (4) in almost the same way as human skin or clothing, this radiant heat is absorbed by the radiant heat absorbing plate (4).
3). And temperature sensing element (2)
The radiant temperature is detected by the radiant heat transmitted from the radiant heat absorbing plate (3), and the indoor unit is controlled by this temperature signal.

, which ensures that radiant heat passes through and is transmitted, and also reliably prevents the influence of external convective heat transfer caused by air blowing, etc. Furthermore, since the sides and rear of the radiant heat absorbing plate (3) are covered with a heat insulating case (5), external heat is not transferred to the absorbing plate (3). ) is formed to a thickness that does not cause natural convection, so heat will not be transferred to the absorption plate (3) due to this convection, and the temperature sensing element (2) will accurately detect radiant heat.

This results in detection of radiant temperature with a good degree. Furthermore, it can be understood that by making the case (5) thicker (see d), external heat is reliably blocked. Based on these experimental results, the radiant temperature detector (1) is configured by taking into consideration the external dimensions and setting the thickness of the air insulation H (9).

よく行うことができる。(Effects of the Invention) As described above, according to the radiant temperature detector of the present invention, the temperature detection element detects the temperature of the radiant heat absorption plate, and the radiant heat is emitted from the front of the radiant heat absorption plate through the air insulation layer. Because it is covered with a transparent film, the radiant heat absorbing plate receives radiant heat on the front side and the temperature detection element detects the radiant temperature, so the radiant heat receiving area is widened, the amount of heat received is large, and the radiant temperature is accurate. Since it is detected, air conditioning control etc. can be performed with high precision.

The radiant heat will surely pass through and be transmitted to the absorption plate. Furthermore, since the air insulation layer is formed to a predetermined thickness such as 5II11 to 10 mm, natural convection does not occur, heat transfer due to convection can be reduced, and the accuracy of convergence 1>11ff1 degree can be improved. can.
