≪Experiment outline≫
As shown in FIGS. 1 and 2, by arranging four heat insulating materials 1 of 1 m in length and width and 25 mm in thickness in a plane square shape, a hollow rectangular tube having a square cross section having an upper end opening 2 and a lower end opening 3 is provided. Shaped chamber 4 was produced. For convenience, each of the four surfaces as the side walls of the chamber 4 is defined as an A surface, a B surface, a C surface, and a D surface 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. Between the lower end opening 3 of the chamber 4 and the floor surface 6, a gap is formed from the lower end opening 3 so as not to block the lower end opening 3, and the thickness of the outer dimension of 50 mm that protrudes uniformly around the chamber 4 is A bottom heat insulating material 7 was provided. The lower end opening 3 of the chamber 4 was communicated with the indoor space of the test chamber 5 through a gap with the bottom heat insulating material 7 over the entire circumference of the chamber 4.

  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 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 heat insulating material 7. Ventilation in the chamber 4 was ensured.

  A radiant heat source was provided so as to face any one of the four surfaces of the chamber 4. The radiant heat source was configured by installing two 800 watt heaters 2 on the two upper and lower shelf plates of the rack 9. The radiant heat of the radiant heat source (heater 8) was applied to one surface (A surface) 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 experiment module 11 was installed at the center position in the height direction of the chamber 4 and equidistant from the four surfaces by being suspended from the support bar 10 in the space inside the chamber 4.

  As shown in FIG. 3, the experimental module 11 has a suspension bar 12 suspended from a support bar 10 so as to be rotatable around a longitudinal axis, and a black sphere temperature in the form of a sphere having a radius of 20 mm attached to the lower end of the suspension bar 12. Two hemispherical black sphere thermometers with a radius of 20 mm (pairs of suspension rods) provided in pairs on the left and right at the same height above the black bulb thermometer 13 with respect to the total 13 (glb) and the suspension rod 12 The bottom sphere-shaped black sphere thermometer is equally divided into two: divided sphere-shaped black sphere thermometer) 14 (hGx1, hGx2) and the same height position as these hemispherical black sphere thermometers 14 And an air thermometer 15 (temp) provided on the suspension rod 12 so as to be positioned between these hemispherical black sphere thermometers 14.

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

  Each of the two hemispherical black sphere thermometers 14 was provided with a heat insulating material 14a having a thickness of 30 mm with an aluminum coating on the flat surface side of the hemisphere. In order to avoid the air thermometer 15, the two hemispherical black sphere thermometers 14 are arranged at an equal distance from the suspension rod 12 so that the heat insulating materials 14 a face each other with the air thermometer 15 interposed therebetween. Installed away. As shown in the figure, the two hemispherical black sphere thermometers 14 are made to have different directions of 180 ° in the left-right direction so that the hemispherical surfaces face each other.

  The suspension rod 12 can be rotated around the axis of the support bar 10 manually or automatically, and the angle of each hemispherical black sphere thermometer 14 is changed so that their orientation in the chamber 4 Changed so that it can be directed to any of the four surfaces (A, B, C, D). The hemispherical black sphere thermometers 14 paired on the left and right are referred to as a first thermometer 14 and a second thermometer 14 for convenience. The inside of the test chamber 5 was kept at 18 to 24 ° C. by air conditioning control.

  In the experiment, in order to change the direction 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. Measured value glb, measured value temp by air thermometer 15, measured value hGx1 by first thermometer 14, and measured value hGx2 by second thermometer 14.

  FIG. 4 shows a graph of measurement results. The horizontal axis of the graph indicates the measurement time, and the vertical axis indicates 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 sphere 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.

  In addition, as shown in FIG. 5, the first thermometer 14 (hGx1) faces the A surface (the surface from which radiant heat is released; hereinafter referred to as the hot surface), and the second thermometer 14 (hGx2) ) Is a position in a state of facing the C surface on the opposite side of 180 °. Similarly, PT3 is a position in a state 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 of 180 °. Furthermore, 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 of 180 °. In this position, the first thermometer 14 (hGx1) faces the B surface and the second thermometer 14 (hGx2) faces the D surface on the opposite side of 180 °.

  When the first thermometer 14 is PT1 near the A surface (hot surface), the measured values glb, hGx1 of the black bulb thermometer 13 and the first thermometer 14 approach, and the measured value hGx2 of the second thermometer 14 separates. . When the second thermometer 14 is PT3 in the vicinity of the A plane, the measured values glb and hGx2 of the black bulb thermometer 13 and the second thermometer 14 approach and the temperature similarly changes with time. The measured value hGx1 of the first thermometer 14 is separated. From these, 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 close to the measured value glb of the black bulb thermometer 13, respectively. .

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

pGx = Max (hGx1, hGx2) (1)

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

  Next, when the first and second thermometers 14 are in an uneven positional relationship with respect to the A surface (hot surface), and when both are in an equal positional relationship, “is anisotropic” or not. The anisotropy was investigated.

  As shown in FIG. 5, the rotation pattern shown in FIG. 7 is such that one of the two first and second thermometers 14 faces the A surface (hot surface) and the other does not face the A surface at all. The case of PT3 and the case of PT2 and PT4 in which the two thermometers 14 are both equidistant from the A plane and can be affected by radiation from the A plane are classified. The measurement value obtained by the former is a data group having radiant heat anisotropy, and the measurement value obtained by the latter is a data group having no radiant heat anisotropy.

  If the anisotropy of heat radiation can be detected from the measured values hGx1 and hGx2 of the two first and second thermometers 14, the arrival direction of the radiant heat can be grasped. As a result, the thermal environment can be grasped and used for air conditioning control.

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

X1 = Max (hGx1, hGx2) (3)

X2 = Min (hGx1, hGx2) (4)

X3 = temp (5)

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

  In addition, as understood from the relationship with FIGS. 4 and 6 in the graph, PT1 and PT3 have anisotropy (C = 1), and PT2 and PT4 have no anisotropy. (C = 0). Furthermore, 8 minutes after the direction change is considered as an unsteady state in which the temperature in the first and second thermometers 14 changes, and is excluded as data that cannot be determined for anisotropy.

  Based on the experimental results, classifying the data group having anisotropy, the data group having no anisotropy, and the data group that is not any according to X1 to X3 in the above formulas (3) to (5); did.

FIG. 9 shows the relative relationship between the values of X1 to X3. As can be understood from this figure, the value of X2 is always located between the value of X1 and the value of X3. In the data group having anisotropy that can be seen from the graph of FIG. 8, the value of X2 is relatively lower toward the value of X3 (lower temperature), and on the other hand, the data group having no anisotropy. Then, since the value of X2 is closer to the value of X1 and is located on the upper side (temperature is higher), the average value (weighted average method) weighted (w) to the value of X1 and the value of X3 By using the following formula (2) representing the above) and comparing the weighted average value with the value of X2, depending on whether the average value is higher (temperature is higher) or lower (temperature is lower) It was found that anisotropy can be determined. The weighting is a value that is appropriately set depending on the size of a spherical cover (described later) of the divided spherical black sphere thermometer 14, the sensitivity of the first and second thermometers 14, and the like.

X2 ≦ wX1 + (1-w) X3 with anisotropy
(2)
X2> wX1 + (1-w) X3 No anisotropy

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

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

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