≪Experiment outline≫
As shown in FIGS. 1 and 2, by arranging four heat insulating materials 1 having a length and width of 1 m and a thickness of 25 mm in a square planar shape, a hollow square cylinder having a square upper end opening 2 and a lower end opening 3 has a square flat cross section. A shaped chamber 4 was manufactured. For convenience, each of the four side walls of the chamber 4 is designated as the A side, the B side, the C side, and the D side in a counterclockwise direction.

The chamber 4 was installed so as to float from the floor surface 6 in the test chamber 5 so that the lower end opening 3 was not blocked. A gap is provided between the lower end opening 3 of the chamber 4 and the floor surface 6 from the lower end opening 3 so as not to block the lower end opening 3, and the thickness of the external dimension is 50 mm so as to uniformly protrude around the chamber 4. A bottom heat insulating material 7 was provided. The lower end opening 3 of the chamber 4 communicated with the indoor space of the test chamber 5 over the entire circumference of the chamber 4 through a gap with the bottom surface insulating material 7.

The upper end opening 2 of the chamber 4 was opened to the test chamber 5 and communicated with the indoor space of the test chamber 5. Then, the air flow F naturally moves back and forth between the inside of the chamber 4 and the test chamber 5 by the upper end opening 2 of the chamber 4 and the gap between the lower end opening 3 of the chamber 4 and the bottom surface insulating material 7. Ventilation in the chamber 4 was ensured.

The radiant heat source was provided so as to face any one of the four surfaces of the chamber 4. The radiant heat source was composed of four 800 watt heaters 8 installed on two upper and lower shelves of the rack 9. The radiant heat of the radiant heat source (heater 8) is applied to one surface (plane A) facing the radiant heat source.

A support bar 10 is provided in the upper end opening 2 of the chamber 4 so as to pass through the center of the upper end opening 2 between a pair of heat insulating materials 1 facing each other. The experimental module 11 was suspended from the support bar 10 into the space inside the chamber 4, and was installed at the center position in the height direction of the chamber 4 and at a position equidistant from the four surfaces.

As shown in FIG. 3, the experimental module 11 has a hanging rod 12 rotatably suspended around the length axis and a black sphere temperature having a radius of 20 mm attached to the lower end of the hanging rod 12. Two hemispherical black sphere thermometers with a radius of 20 mm (of the hanging rod) provided so as to form a pair on the left and right at the same height position above the black sphere thermometer 13 with respect to the total 13 (glb) and the hanging rod 12. The size of the sphere-shaped black sphere thermometer at the lower end is evenly divided into two: the divided spherical black sphere thermometer) 14 (hGx1, hGx2) and the same height position as these hemispherical black sphere thermometers 14. It was composed of an air thermometer 15 (temp) provided on the hanging rod 12 so as to be located between these hemispherical black sphere thermometers 14.

The black globe thermometer 13 and the hemispherical black globe thermometer 14 are arranged at different heights so as not to interfere with each other when receiving radiant heat. The air thermometer 15 was attached to the suspension rod 12 after being covered with an aluminum cylindrical membrane 15a in order to avoid the influence of radiant heat.

Each of the two hemispherical black globe thermometers 14 was attached with a heat insulating material 14a having a thickness of 30 mm and having an aluminum coating on the flat surface side of the hemisphere. Since the two hemispherical black globe thermometers 14 avoid the air thermometer 15, the heat insulating materials 14a face each other so as to sandwich the air thermometer 15 and are equidistant from the hanging rod 12. Installed apart. As shown in the figure, the two hemispherical black globe thermometers 14 are oriented 180 ° in the left-right direction so that the hemispheres face opposite to each other.

The suspension rod 12 allows the support bar 10 to rotate manually or automatically around the axis of the rod, and the angle of each hemispherical black globe thermometer 14 is changed so that the orientation thereof in the chamber 4 is changed. I changed it so that it can be directed to any of the four faces (A, B, C, D). For convenience, the first thermometer 14 and the second thermometer 14 are used for each of the hemispherical black globe thermometers 14 paired on the left and right. The inside of the test room 5 was kept at 18 to 24 ° C. by air conditioning control.

In the experiment, in order to change the directions of the first and second thermometers 14 and 14 for about 6 hours, the experiment module 13 is rotated by a predetermined angle in one direction every time a predetermined time elapses, and the black ball thermometer 13 The measured value glb, the measured value temp by the air thermometer 15, the measured value hGx1 by the first thermometer 14, and the measured value hGx2 by the second thermometer 14 were obtained.

FIG. 4 shows a graph of the measurement results. The horizontal axis of the graph shows the measurement time, and the vertical axis shows the temperature. In the graph, the chain line is the measured value temp of the air thermometer, the dotted line is the measured value gbl of the black globe thermometer, the thick solid line is the measured value hGx1 of the first thermometer, and the thin solid line is the measured value hGx2 of the second thermometer.

Further, with PT1, as shown in FIG. 5, the first thermometer 14 (hGx1) faces the A surface (the surface on which radiant heat is emitted; hereinafter referred to as the thermal surface), and the second thermometer 14 (hGx2) ) Is the position facing the C surface on the opposite side of 180 °. Similarly, PT3 is a position in which the second thermometer 14 (hGx2) faces the A surface and the first thermometer 14 (hGx1) faces the C surface on the opposite side by 180 °. Further, PT4 is a position in which the first thermometer 14 (hGx1) faces the D surface and the second thermometer 14 (hGx2) faces the B surface on the opposite side by 180 °. The position is such that the first thermometer 14 (hGx1) faces the B surface and the second thermometer 14 (hGx2) faces the D surface 180 ° opposite.

When the first thermometer 14 is PT1 near the A surface (heat surface), the measured values glb and hGx1 of the black globe thermometer 13 and the first thermometer 14 approach each other, and the measured values hGx2 of the second thermometer 14 move away from each other. .. Further, when the second thermometer 14 is PT3 near the A plane, the measured values glb and hGx2 of the black bulb thermometer 13 and the second thermometer 14 approach each other, and the temperature changes similarly with time. , The measured value hGx1 of the first thermometer 14 is separated. From these facts, it was found that the maximum values of the measured values hGx1 and hGx2 of the first thermometer 14 and the second thermometer 14 are closely related to the measured value glb of the black globe thermometer 13, respectively. ..

The graph of FIG. 6 applies the following equation (1) expressing the above relationship as a predicted value (Predicted Gx; pGx) with respect to the measured value glb of the black globe thermometer 13. The horizontal axis of the graph shows the measurement time, and the vertical axis shows the temperature. In the graph, the chain line is the measured value temp of the air thermometer 15, the dotted line is the measured value glb of the black globe thermometer 13, and the solid line is the predicted value.

pGx = Max (hGx1, hGx2) …… (1)

Even after 19:00 when the rotation pattern was changed, the predicted value pGx was almost the same as the measured value glb of the black globe thermometer 13, and it was confirmed that the predicted value pGx was appropriate.

Next, the case where the first and second thermometers 14 have an unequal positional relationship with respect to the A surface (heat surface) and the case where both have an equal positional relationship are referred to as "anisotropic / non-anisotropic". The anisotropy to be observed was examined.

In the rotation pattern shown in FIG. 7, as shown in FIG. 5, one of the two first and second thermometers 14 faces the A surface (thermal surface), and the other does not face the A surface at all. It can be divided into two types: the case of PT3 and the case of PT2 and PT4, both of which have two thermometers 14 equidistant from the A plane and can be affected by radiation from the A plane. The measured value obtained by the former is defined as a data group having radiant heat anisotropy, and the measured value obtained by the latter is defined as a data group having no radiant heat anisotropy.

If the anisotropy of thermal radiation can be detected from the measured values hGx1 and hGx2 of the two first and second thermometers 14, the direction of arrival of radiant heat can be grasped. This makes it possible to grasp the thermal environment and also utilize it for air conditioning control.

A method of detecting anisotropy was examined from the measured values temp of the air thermometer 15 and the measured values hGx1 and hGx2 of the two first and second thermometers 14. FIG. 8 is created by arranging the measurement results of the above experiment by the following formulas (3) to (5). The horizontal axis of the graph shows the measurement time, and the vertical axis shows the temperature.

X1 = Max (hGx1, hGx2) …… (3)

X2 = Min (hGx1, hGx2) …… (4)

X3 = temper …… (5)

Equation (3) is the maximum value of the measured values hGx1 and hGx2 of the first and second thermometers 14, which are indicated by Δ in the graph, and equation (4) is the measurement of the first and second thermometers 14. The minimum values of the values hGx1 and hGx2 are indicated by ■ in the graph, and equation (5) is the measured value temp of the air thermometer 15 and is indicated by ○ in the graph.

Further, in the graph, as can be understood from the relationship with FIGS. 4 and 6 above, the case of PT1 and PT3 is regarded as having anisotropy (C = 1), and the case of PT2 and PT4 is regarded as having no anisotropy. (C = 0). Further, 8 minutes after the direction change is considered as an unsteady state in which the temperatures in the first and second thermometers 14 change, and is excluded as data for which anisotropy cannot be determined.

Based on the experimental results, the data group having anisotropy, the data group having no anisotropy, and the data group having neither anisotropy are classified by X1 to X3 of the above formulas (3) to (5). did.

FIG. 9 shows the relative relationship between the values of X1 to X3, and as can be seen from this figure, the value of X2 is always located between the value of X1 and the value of X3. In the data group with anisotropy as can be seen from the graph of FIG. 8, the value of X2 is located on the lower side (low temperature) relatively closer to the value of X3, while the data group without anisotropy is present. Then, since the value of X2 is located on the upper side (higher temperature) toward the value of X1, the average value (weighted averaging method) obtained by weighting (w) the value of X1 and the value of X3. Is applied), and by comparing the weighted average value with the value of X2, it depends on whether it is above (higher temperature) or lower (lower temperature) than the average value. , It was found that it is possible to judge the anisotropy. The weighting is a value appropriately set according to the size of the spherical cover (described later) of the split spherical black globe thermometer 14, the sensitivity of the first and second thermometers 14, and the like.

X2 ≤ wX1 + (1-w) X3 with anisotropy

X2> wX1 + (1-w) X3 No anisotropy

Here, X1 = Max (hGx1, hGx2)
X2 = Min (hGx1, hGx2)

<< Embodiment >>
Based on the findings obtained from the above experiment, as shown in FIG. 10, the center J in any plane Q in the space S including the center J is centered on the radiant heat measurement point of the space S for measuring the radiant heat. A divided spherical black globe thermometer 14 is installed on each of the plurality of radiations R from the above, respectively, at equal distances from the center J and formed into a size obtained by equally dividing the spherical black globe thermometer into at least two. , For each black sphere temperature hGx1, hGx2, ..., HGxn measured by each of these divided spherical black sphere thermometers 14.

pGx = Max (hGx1, hGx2, ..., hGxn) (1)

Is applied, and pGx is used as a predicted value with respect to the value measured by the black globe thermometer at the radiant heat measurement point, and the radiant heat in the space S for measuring the radiant heat is estimated.

In the illustrated example, two hemispherical split spherical black globe thermometers 14 are installed on each of the two radiations R along the X direction from the center (radiant heat measurement point) J of the XY coordinate system, and the center J. The case where four hemispherical split spherical black globe thermometers 14 are installed on each of the four radiation Rs along the XY2 direction is shown. In the latter case, the distances from the center J to each divided spherical black globe thermometer 14 may be equidistant in each of the X and Y directions.

The divided spherical black globe thermometer 14 may be formed by forming a spherical black globe thermometer (corresponding to the black globe thermometer 13 in the experiment) into a size evenly divided by the number of radiations R. That is, the four divided spherical black globe thermometers 14 provided along the XY2 direction may be in the form of dividing the sphere into four.

Here, conventionally, the function of converting the black globe temperature of a so-called regular size black globe thermometer to the average radiation temperature (MRT) and the inverse function of converting the average radiation temperature to the black globe temperature of the black globe thermometer are known. Along with that, a function that converts the black globe temperature of a small size black globe thermometer into an average radiation temperature is known, and the black bulb temperature of a small size black globe thermometer is converted to that of a regular size black globe thermometer. It is known to convert to black globe temperature and vice versa.

On the other hand, in the present embodiment, in the configuration in which the spherical black globe thermometer in which the above experiment is performed is divided into a plurality of parts, the size of the divided plurality of divided spherical black globe thermometers 14 can be reduced from the whole. When converting to the black bulb temperature of a regular size black globe thermometer, the above formula (1) is applied, which makes it possible to make the conventional black globe thermometer compact in a divided manner. At the same time, a method for estimating radiant heat by at least two or more divided spherical black globe thermometers 14 obtained by dividing the black globe thermometer has been established.

On the other hand, the conventional sphere-shaped black sphere thermometer can measure the average radiant temperature of heat radiation coming from the surroundings, but determines the direction of arrival of heat radiation, for example, from which direction the heat radiation is strong. I couldn't. On the other hand, from the knowledge obtained from the above experiment, it was found that the direction of arrival of radiant heat can be specified.

That is, the air temperature T of the space S (FIGS. 7 and 7 and FIG. 7) is within the installation range of the divided spherical black sphere thermometer 14 and at or near the radiant heat measurement point (center J) of the space S for measuring the radiant heat. An air thermometer for measuring the measured value temp = X3) of the air thermometer 15 described in 8 is installed, and the divided spherical black sphere thermometer 14 of any two of the plurality of divided spherical black sphere thermometers 14 is installed. For black ball temperature hGx1, hGx2 and air temperature T of the air thermometer

X2 ≤ wX1 + (1-w) T with anisotropy
(2)
X2> wX1 + (1-w) T No anisotropy

Here, X1 = Max (hGx1, hGx2)
X2 = Min (hGx1, hGx2)

By applying, the direction of arrival of radiant heat in the space S for measuring radiant heat is estimated.

This makes it possible to specify the direction of arrival of thermal radiation, which was not possible with a conventional black globe thermometer, and enhances its availability.

Further, the receiver 20 controls various control devices by using the radiant heat, the arrival direction of the radiant heat, the humidity value, and the illuminance value.

According to the radiant heat estimation method and the radiant heat measuring device by the divided spherical black sphere thermometer according to the present embodiment described above, the radiant heat measuring point of the space S for measuring the radiant heat is set as the center J, and the space S including the center J is included. On each of the plurality of radiations R from the center J in any of the planes Q, the sphere-shaped black sphere thermometers were formed at equal distances from the center J so as to be evenly divided into at least two sizes. Alternatively, a divided spherical black sphere thermometer 14 formed by uniformly dividing a spherical black sphere thermometer by the number of radiation R is installed, and each of these divided spherical black sphere thermometers 14 measures.
