ずしも有効ではなかった。2. Description of the Related Art One of the important factors that determine the product quality of polyester filament, which is an excellent fashion material, is the atmosphere in a spinning and drawing room. To keep this atmosphere constant, the synthetic fiber factory controls temperature, humidity, and internal pressure with large-scale air conditioning equipment. Conventionally, in the method used for controlling the atmosphere, the control of temperature and humidity is performed solely by PID control, and the control of the mixture ratio is performed by computer control. However, although this method can stabilize the atmosphere, it consumes a large amount of energy for heating and cooling air, and thus is not always effective from the viewpoint of energy saving.

In other words, the load of chilled water production by a refrigerator can be reduced in summer, and the amount of steam used can be reduced by taking in an appropriate amount of outside air in winter.
A significant energy saving effect can be expected. However,
Conventionally, computer control is a one-input, one-output control method in which the temperature of mixed air is used as an input parameter, and the mixing ratio of outside air and return air is used as an output parameter. And a sufficient control effect was not obtained.

The temperature of the mixed air in which the outside air and the return air are mixed is calculated from the temperature of the outside air taken in from the outside air duct, the temperature of the return air returning from the room, the amount of the outside air taken in, and the amount of the return air. Comparing the calculated temperature of the mixed air with a preset target temperature, and controlling the intake amount of outside air so that the temperature of the mixed air approaches the target temperature. Based on the temperature of the water flowing through the nearby river ,
The method of HVAC, characterized by further determining a fuzzy inference according to the rules. IF TK = LL THEN TA = HI F TK = L THEN TA = O IF TK = O THEN TA = L IF TK = H THEN TA = LL where TK is the water temperature of the river, TA is the target temperature, and LL
Is "very low", L is "low", O is "medium"
And H represents “high”.
