Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiant heat air conditioner for cooling and heating by radiant heat.

[0002]

2. Description of the Related Art When air conditioning is performed using radiant heat from a radiant panel, there is one that detects the room temperature and compares the detected value with a set temperature to control the radiant heat of the radiant panel. For example, it is the invention described in Japanese Patent Publication No. 62-62265. The radiant heat control of the radiant panel in the present invention is performed by the temperature sensor detecting the surface temperature on the ceiling surface where the radiant panel is installed or the wall surface where the radiant panel is not installed, or the air temperature in the immediate vicinity from these surfaces. It has been implemented.

[0003]

However, in the radiant cooling and heating apparatus described in the above publication, the temperature sensor is installed on the ceiling surface where the radiant panel is installed or in the vicinity thereof, and the air temperature thereof is detected and used as the room temperature. In this case, it means that the temperature close to the surface temperature of the radiation panel is detected rather than the room temperature. Therefore, the detected temperature cannot be said to be a temperature representative of the indoor temperature, and there is a possibility that the radiant cooling / heating device described in the publication cannot provide a comfortable indoor environment. If the temperature sensor is installed too far from the radiation panel surface,
Although it is possible to detect the typical temperature in the room, it is not aesthetically pleasing.

Further, since a wall, floor, etc. on which the radiation panel is not installed has a larger heat capacity than air, a temperature sensor is installed on the wall surface on which the radiation panel is not installed or in the vicinity thereof, and these walls and When the air temperature near the floor is detected as a typical indoor temperature, the detection becomes slower than the actual indoor temperature change. For example, if the radiant cooling / heating device cools the room when the initial temperature is high, the specific heat of the wall or floor becomes larger than the air in the room, and the decrease in the detected temperature becomes extremely small. Surface temperature is higher than indoor air temperature. Therefore, also in this case, the detected temperature cannot be said to be a typical temperature in the room, as in the case where the temperature sensor is installed on or near the surface of the radiation panel.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a radiant cooling / heating apparatus capable of providing a comfortable indoor environment without impairing the aesthetics of the room.

FIG. 1 is an internal perspective view of a room to which a first embodiment of a radiant cooling / heating apparatus according to the present invention is applied. FIG. 2 is a block diagram showing a control system of the radiant cooling / heating apparatus of FIG.
FIG. 3 is a flowchart showing the operation of the control system of FIG. FIG. 4 is an enlarged front view showing the temperature sensor module of FIG. FIG. 5 is a vertical cross-sectional view of the room shown in FIG. 1 in which the temperature distribution is displayed, taken along a plane including a human. FIG. 6 is a temperature change graph during cooling in the vicinity of the radiation panel surface. FIG. 7 is a temperature change graph at the time of heating near the surface of the direct sunlight panel.

A room 1 shown in FIG. 1 has a radiant cooling / heating device 2
As shown in FIG. 2, this is a room to be cooled and heated, and in this embodiment, a radiation panel 4 is installed on the ceiling 3.
The radiant cooling / heating device 2 controls the radiant heat radiation amount of the radiant panel 4, and as shown in FIG. 2, a surface temperature sensor 5 as a surface temperature detecting means, an air temperature sensor 6 as an air temperature detecting means, The inference unit 7 and the control unit 8 are included.

Surface temperature sensor 5 and air temperature sensor 6
As shown in FIGS. 1 and 4, is installed in the temperature sensor module 9 that is installed so as to project from the radiation panel 4. The surface temperature sensor 5 is arranged in a portion of the temperature sensor module 9 which is embedded in the radiation panel 4, and detects the surface temperature of the radiation panel 4. Further, the temperature sensor module 9 projects from the radiation panel 4 by the projecting amount L, and the air temperature sensor 6 is arranged at one or more, for example three, at the projecting direction of the temperature sensor module 9 at appropriate intervals. . The protrusion amount L is set to several cm to several tens of cm. Therefore, the three air temperature sensors 6 detect the air temperatures near the surface of the radiation panel 4 at the respective arrangement positions.

Here, in the room 1 at 24 ° C.,
FIG. 5 shows the air temperature distribution in a steady state when the surface temperature of the radiant panel 4 is cooled to, for example, 18 ° C. From the isotherm 15 of FIG. 5, the air temperature distribution in the room 1 is in the steady state except for the vicinity of the surface of the radiation panel 4 installed on the ceiling surface 3 and the surroundings of the person 10 in the center of the room 1 and above. It can be seen that the temperature is almost constant (22.5-23 ° C). Particularly, the temperature rises above the human 10 due to heat radiation from the human 10, but the temperature at the radiation panel 4 outside the human 10 is several degrees from the surface of the radiation panel 4.
It is equal to the above constant temperature at a position below cm. This constant temperature is a representative suitable temperature for closing most of the room 1 (indoor representative temperature), and therefore the air temperature sensor 6 can also detect this indoor representative temperature.

The inference section 7 includes a neural network (neural network) as a neural network means. This neural network includes a surface temperature sensor 5 and an air temperature sensor 6.
In order to estimate the indoor temperature distribution near the surface of the radiation panel 4 in advance from the surface temperature of the radiation panel 4 and the air temperature near the surface of the radiation panel 4 (which may also include the indoor representative temperature) that are detected respectively in Have been learned. This room temperature distribution is typically shown in FIG. 6 when cooling the room 1 as described above, and when heating the surface temperature of the radiant panel 4 to 30 ° C. in the room 1 at 24 ° C. 7 is a typical example. The neural network further estimates the indoor representative temperature of the room 1 from the indoor temperature distribution.

The control unit 8 controls the radiation heat radiation amount of the radiation panel 4 based on the indoor representative temperature Tr. That is, as shown in FIG. 3, the control unit 8 compares the indoor representative temperature Tr estimated by the inference unit 7 with the set temperature Ta, and when the indoor representative temperature Tr is higher than the set temperature Ta, the radiation is performed. When the indoor representative temperature Tr is lower than the set temperature Ta, the radiation heat radiation amount of the panel 4 is reduced, and the radiation heat radiation amount of the radiation panel 4 is increased.

Next, the operation will be described. As shown in FIG. 3, the user first sets the room temperature to the set temperature Ta.
Here, even if the set temperature Ta is not set in advance by the user, it may be automatically set based on the heat index from the measured values of other heat elements (humidity, airflow, radiant temperature, etc.). Good.

Next, the surface temperature sensor 5 is used to radiate the panel 4.

At the time of cooling the room 1, the air temperature is detected by the three air temperature sensors 6, and is input to the inference unit 7 together with the surface temperature of the radiation panel 4 from the surface temperature line sensor 5, and this inference unit 7 Estimates the indoor temperature distribution shown in FIG. Further, at the time of heating the room 1, the air temperature is detected by at least two air temperature sensors 6 and is input to the inference unit 7 together with the surface temperature of the radiation panel 4 from the surface temperature sensor 5, and the inference unit 7 The room temperature distribution shown in FIG. 7 is estimated.

Thereafter, the control unit 8 compares the indoor representative temperature Tr estimated by the inference unit 7 with the set temperature Ta to control the radiant heat radiation amount of the radiant panel 4 to maintain the room 1 at the set temperature Ta. .

According to the above embodiment, the inference unit 7 uses the temperatures detected by the surface temperature sensor 5 and the air temperature sensor 6.
The neural network of 1 estimates the indoor temperature distribution near the surface of the radiation panel 4 when the room 1 is cooled and heated, and uses this indoor temperature distribution to estimate the temperature at the center of the room as the indoor representative temperature Tr. For this reason, since the indoor representative temperature Tr of the room 1 can be accurately detected, the control unit 8 can optimally control the radiant heat radiation amount of the radiant panel 4, and a comfortable indoor environment can be provided. Moreover, since the air temperature sensor 6 is not arranged at a position far from the surface of the radiation panel 4, the aesthetics of the room 1 is not spoiled.

Infer. This room temperature distribution is typically shown in FIG. 9 when the surface temperature of the radiation panel 4 is set to 18 ° C. to cool the room 1, and the surface temperature of the radiation panel 4 is set to 30 ° C. In the case of heating the room 1, the one shown in FIG. 10 is a typical example. 9 and 10, the distance Y from the front surface of the wall 12 is on the horizontal axis and the temperature T is on the vertical axis.

Further, the inference unit 13 estimates the indoor representative temperature Tr from the estimated indoor temperature distribution. Control unit 8
Controls the heat radiation amount of the radiation panel 4 based on the estimated indoor representative temperature Tr.

According to the above-described embodiment, the inference unit 1 uses the temperatures detected by the surface temperature sensor 5 and the air temperature sensor 6.

An indoor temperature distribution near the surface of the wall 12 in which is not installed is estimated, and the indoor central temperature as the indoor representative temperature Tr is estimated using this indoor temperature distribution. For this reason,
Since the representative temperature Tr can be accurately detected, the control unit 8 can optimally control the radiation heat radiation amount of the radiation panel 4, and a comfortable indoor environment can be provided. Moreover, since the air temperature sensor 6 is not arranged at a position far from the radiation panel 4, the aesthetics of the room 1 is not spoiled.
