Abstract

近年,空調システムの最適制御,最適運転,コミッショニングが注目されているが,その検討には空調システムで使用される機器それぞれの動特性把握が不可欠である.特に室温を計測するセンサは,その出力信号で空調システムの最も主要な制御対象である室温が制御され,また間接的には熱源システムの制御動作にも影響が及ぶので非常に重要である.しかし,センサの動特性を究明した既往の研究例はほとんどない.そこで本研究では,種々の条件のもと実験室実験と現実の室内での実測を実施し,室温センサの時定数を見いだし検討を加えた.

The main object of HVAC system is to control room air temperature accurately. Because the signal transmitted from a room air temperature sensor governs the behavior of the overall HVAC system, it is important to obtain the precise dynamic behavior of indoor air temperature sensors. In our report time constant, which is fundamentaly used to express the dinamic response of the sensors, is considered as the value expressing the dynamic behavior. However, time constants of common indoor air temperature sensors used for HVAC control systems are unclear and not much research works were done. Therefore, in this report, time constants were cleared from the experimental reserach at a laboratory, and in an actual room. As a result, the time constants were recommend for the automatic control design. The non-liner heat transfer models were used to identify time constants which were discussed by comparing to ones obtained by experiment.
