Abstract

PURPOSE:To permit to control the indoor temperature by controlling air force, air direction and radiating heat amount by a method wherein a temperature measuring device, capable of measuring temperature distribution in the whole of a room by measuring a time from the radiation of infrared-ray to the reception of the same as well as a time from the transmission of sound wave to the reception of the same, is provided in the device. CONSTITUTION:An infrared-ray radiating and receiving device 11 radiates the infrared-ray to an arbitrary direction in the room and receives the infrared-ray reflected from the wall surface of the room. A sound wave transmitting and receiving device 12 transmits the sound wave to the same direction as the direction of the radiated infrared-ray and receives the sound wave reflected from the wall surface existing in the direction. A distance to the wall is determined by the time from the radiation to the reception of the infrared-ray and the velocity of sound at that time is determined by the time from the transmission to the reception of the sound wave. According to this method, the temperature distribution in the direction, into which the sound wave is transmitted, may be determined. The radiating directions of the infrared- ray and the sound wave are changed sequentially to measure the distributing condition of the temperature. A control unit 15 corrects the air force, air direction and the heat amount of warm-air or cool air of a warm-air and cool air generating device 1 in accordance with the temperature distribution in respective directions.

g) calculates the temperature in each direction area of the room from the sound wave transmitting/receiving device (2) from the measured values from the measuring device (131), and calculates the temperature in each direction area of the room from the sound wave transmitting/receiving device (2), This is a control device that controls wind power, wind direction, and amount of heat.

FIG. 3 is an explanatory diagram showing the operation of an embodiment of the present invention, and in the figure, α armor, and θ→ indicate the same parts as the same reference numerals in FIG.

Next, the operation will be explained. Hot air/cold air generator (1)
generates hot or cold air with the wind force, wind direction, and heat amount set by the control device 4. As shown in FIG. 3, the old infrared radiation/reception device emits infrared rays in any direction within a room and receives the infrared rays reflected from a wall surface existing in the direction of the radiation. In addition, the sound wave transmitting and receiving device 0 also transmits sound waves in the same direction as the emitted infrared rays, as shown in Figure 3.
Receives sound waves reflected from walls in that direction.

The time from the time the infrared rays are emitted by the infrared radiation/receiving device Uυ to the time the emitted infrared rays are received
2) The measuring device 131 measures the time from the time of transmitting the sound wave to the time of receiving the transmitted sound wave, and detects a change in temperature in the area in the same direction. The distance from the installation position of the device to the wall where the infrared rays were reflected can be determined by the time from when the infrared rays are emitted to the time they are received, and the speed of sound at that time can be determined from the time from when the sound waves are transmitted to the time they are received. Since the speed of sound is a linear function of temperature, the temperature of the area through which the sound wave has passed, that is, the direction in which the sound wave was transmitted, can be determined from the speed of sound.

By sequentially changing the direction in which the sound waves are emitted and determining the speed of sound in each predetermined direction, the state of temperature distribution can be determined.

The control device αυ adjusts the temperature in each direction to
To correct the wind force, wind direction, and heat amount of hot air or cold air generated by the cold air device (1). In the above manner, the indoor temperature is controlled.

The temperature measuring device (IL4) is integrated with the hot/cold air generator (1) and the control device (2), making the entire device compact, easy to handle, and low cost.

In the above, we have only explained the case where it is used to control the temperature of indoor air conditioning, but since it can detect the temperature rise in the event of a fire, it can also be used as a fire detector to detect unevenness in the indoor temperature distribution. It can also be used as a detector to control the opening of doors.

〔Effect of the invention〕

As described above, according to the present invention, the entire device is integrated, can be made smaller, easier to handle, and can be manufactured at a lower cost. In addition, since it is corrected according to the temperature distribution in the room, it can be controlled with high precision. There is.
