Abstract

PURPOSE:To regulate an indoor temperature and to rapidly cope with a change in an indoor temperature by a method wherein indoor noise is detected by a detecting means arranged in a room, and based on a change in detecting noise, air conditioning equipment is controlled. CONSTITUTION:Since when devices 46, 46, and 46 are started to operate, fans mounted on the devices 46, 46, and 46 are run, the generation of indoor noise is increased. The increased noise is detected by a microphone 12, and detecting noise is converted into an electric signal by means of an electric system 42. The converted electric signal is transmitted to a sonic analyzing device 30 through a control device 34. In which case, an inputted sound wave is analyzed to confirm working of the devices 46, 46, and 46, and it is considered that a thermal load is increased. Based on a signal transmitted from the sonic analyzing device 30 to the control device 34, a signal is transmitted to a regulating valve 26. In which case, the opening of the regulating valve 26 is increased, and an amount of refrigerant fed in an air conditioning unit 14 is increased. Thus, cooling capacity of a coil in the air conditioning unit 14 is increased and low temperature air is discharged through a discharge port 15.

[Effect]

According to the present invention, a detection means is installed indoors, the detection means detects the sound in the room, the detected sound is converted into an electrical signal, and the control unit of the air conditioning equipment is sent based on the change before detection. It sends signals to control air conditioning equipment and can regulate indoor temperature.

Furthermore, the detection means for detecting indoor sounds can be provided in conjunction with existing broadcasting equipment that is normally installed in each room of an office building. That is, by connecting the electrical system of the existing speaker installed in each room and the microphone according to the present invention with the same wiring, the wiring equipment of the speaker can be used for detecting indoor sounds.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the air conditioning equipment control method and control device according to the present invention will be described in detail below with reference to the accompanying drawings.

Figure 1 shows air conditioning equipment 1 installed in room 10 in an office.
2 is shown.

The air conditioning unit 14 of the air conditioning equipment 12 is connected to the ceiling 16 of the room 10.
It is set in. An air outlet 17 is provided at the bottom of the air conditioning unit 14, and a fan and a coil (not shown) are provided inside.

A heat medium pipe 18.20 is connected to this coil, and the pipe 18.20 is connected to a heating/cooling device 22.

The heating and cooling device 22 is a control unit! 24 to adjust the heating and cooling of the heat medium. This control unit W24 is a heating and cooling device! In addition to adjusting f22, the opening degree of the valve 26 of the pipe 18 is adjusted. The control device 24 operates based on instructions from the temperature sensor 28 and the acoustic wave analyzer 30. Temperature sensor 28 is on ceiling 1
It is provided near the suction port 32 disposed at 6.

The sound wave analysis device 30 receives a signal from a broadcasting device 34, which will be described later, and the broadcasting device 34 has a microphone 40 and an electrical system 42.
receive a signal from. In this case, the microphone 40 and the electrical system 42 are installed on a wall 44 near the ceiling 16 using the wiring of the speaker devices existing in the room 10, including the speaker 36, the electrical system 38, and the broadcasting device 34. In addition, 46, 46, 46 on Fig. 1 are the equipment that becomes the heat load source,
48 is a temperature setting device.

The operation of the air conditioning equipment control method and control device according to the present invention configured as described above will be explained.

First, the air conditioning unit 14 and the control device 24 are operated so that the indoor temperature is maintained at a constant temperature by the setting device 48, so that the room is in a cooling state. At this time, equipment 46. which becomes a heat load source.
46. 46 is in a stopped state, and heat is only transferred from load windows, walls, etc.

When equipment 46.46.46 starts operating from this situation,
As the fans and the like (not shown) provided in the devices 46, 46, 46 rotate, the indoor sound increases. The microphone 12 detects this elevated sound, and the electrical system 42 converts the detected sound into an electrical signal. The converted electrical signal is sent to the acoustic wave analyzer 30 via the broadcasting device.

Here, the input sound waves are analyzed and the device 46.46.4
6 is confirmed to be operating, and it is considered that the heat load has increased.

A signal is then sent from the sound wave analyzer 30 to the control device 34, and the control device 34 uses the control pulp 26 based on this signal.
