いる。2. Description of the Related Art Normally, during air conditioning in a room, an optimum temperature distribution is required each time in accordance with a change in the indoor / outdoor environment of the room, a sunshine, installation of 0A equipment, population density, and the like. Of course. In view of such a purpose, recently, an air volume adjusting device, a so-called VAV mechanism, is installed near the cool and warm air outlet in the room, and an inverter installed on the air conditioner side is operated together with the air volume adjustment by opening and closing a damper in the VAV mechanism. The adjustment is being made. That is, as described above, the air volume is adjusted by opening and closing the damper mechanism in the air volume adjusting device (VAV) in accordance with the change in the room temperature. However, when the tamper is closed, the air pressure of the air flowing through the duct is reduced. Naturally, the control operation of the conventional inverter device was performed using the pressure difference of the air. In addition to the above, the operation of the inverter is performed using the change of the anemometer.

In addition to the time required, the time difference may cause an uneven phenomenon or the like, and it is extremely difficult to expect and assure a complete operation. In particular, when several air volume adjusting devices (VAV) are installed, the air volume of each air volume adjusting device is naturally different according to the indoor temperature. It was also said to be very uneconomical, requiring a lot of power.

The damper mechanism in the VAV device is opened and closed by communicating with V3 to adjust the amount of air blown from the air outlet. On the other hand, on the air conditioner side, a blower F and a blower inverter 2 that commands the water supply valves P of the cold and hot water coils C and H are installed.
The transmission to the inverter 2 is performed by each VAV according to the blown air volume.
The signals in 1, VAV2 and VAV3 are replaced with certain numerical values, and the control operation of each mechanism device is performed based on the total numerical value. For example, if eight air volume adjusting devices (VAVs) are installed according to the control values of the air volume point integration table in the separate table, the air volume of each of VAV1 to VAV is set to a strong wind (100%) =
4. Medium wind (75%) = 3. Low wind (50%) = 2. Stop (0
%) Replaced with the set numerical value of 0, and installing this in the air conditioning system circuit.-The arithmetic unit 3 performs the integral calculation of the numerical value, and the total value 560 of the integrated values of the numerical values is 560:
The control operation of the blower inverter 2 and the control mechanisms such as the damper mechanism in the air conditioner and the water supply valves P1 and P2 of the cold and hot water coils C and H are controlled by the number of 360 points. Depending on the number of points, the blower inverter 2 and other control mechanisms can be controlled to operate at that rate. Incidentally, based on the above integration table, for example, VAV1-
When the total total air volume of 8 is 140 m 3 / h, the number of points of each air volume corresponds to the above-mentioned air volume value × 4th power, and the maximum number of points is 560 points in total. Therefore, even if the numerical values of the air flow rates in the respective VAVs are different, the control operation is performed at a numerical value of 360, which is far lower than the numerical value of the cumulative value of the point, assuming that the point 560 is 100%. It is energy saving. It should be noted that the total count value based on the number of points described in the above table changes each time due to a change in room temperature or the like, and is not limited to the above numerical values.

As a mechanism on the blower side, air volume adjustment is performed in respective blower passages near air outlets 1a, 1b and 1c formed at appropriate places in a room. The devices (VAV) V1, V2, V3 are installed integrally, and one or several thermoswitches S1, 2, 3 are short-circuited in each of the V1, V2, V3 mechanisms, and the above-mentioned outlets 1a, b, c are short-circuited. A damper (not shown) is installed to be freely openable and closable in order to adjust the amount of air flow. Inside the air conditioner A, the outside air inlet, the return air inlet from the room, and the air inlet are connected to each other through an air passage, and the air blower F, the cold and hot water coils C, H, and the filter are provided in the air passage. , A humidifier, a drain pan, a ventilation passage switching damper mechanism, a silencing mechanism, and other necessary mechanical devices are arranged. In addition, the air volume adjusting device (VAV) and the air conditioner A are connected to the control 4 and the point
The air-conditioning circuit having the arithmetic unit 3 is connected to each other. The air-conditioning control mechanisms, such as the blower F inverter 2 and the water supply valves P1 and P2 of the hot water coils C and H, are controlled based on a command from the control 4. It is configured to open and close to set the air volume and temperature in the room. Note that
As means for short-circuiting, not only a circuit using wiring, but also any means using a wireless circuit such as an optical sensor is possible. Further, the return air port and the air supply port are connected to each of the air outlets 1a, b, and c on the indoor side from the branch chamber B via a duct D provided in the ceiling. The feature of the present invention is that the air volume is strong / medium / weak by VAV1, 2, 3 above.
The stop adjustment result is immediately replaced with the number of points shown in the following table, the number of points is integrated by the arithmetic unit 3, and the total numerical value of the changed air volume is controlled and operated by the control unit 4 at the same time as the air conditioner side. It is possible to open and close each damper mechanism installed at the outside air intake port, the exhaust port, and the return air port, and control all the mechanical devices such as the water supply valves P1 and P2 of the hot water coils C and H. For example, when eight air volume controllers VAV1,2,3 are installed, strong winds, medium winds, weak winds, and the state when stopped, strong winds (100%) 4, medium winds (75%) 3, light winds (50%) 2.
The numerical values in the case where the numerical values of the operation points at the stop (0%) 0 are replaced with the numerical values are as shown in the following table.

However, it is possible to control the inverter 2 and operate the blower with the total value 560 = 360 calculated by integrating and calculating the numerical values in the point / calculation unit 3 and simultaneously perform the control operation of each mechanism device in the air conditioner. You can do it.

Each is replaced with a predetermined numerical value according to the degree of air flow adjustment, such as light breeze (40%) 2, stop (0%) 0, and the like. Therefore, it is natural that the total count value based on the number of points also changes each time with the above change. It should be noted that, even in the constant air flow operation in which the air flow is constant, the water supply valves P1 and P2 can be directly controlled to easily obtain the predetermined room temperature depending on the above numerical command.
