PI 제어 VAV 시스템에 대한 공조공간의 응답 특성

The present study concerns supply-air control in variable air volume (VAV) system with PI control logic. The previously suggested stratified thermal model (multi-zone model can predict local thermal response of an air-conditioned space. A thermal chamber with a PI control logic is built to verify the multi-zone model. The stratified thermal model is used to control supply-air for thermal chamber cooling test. The effects of thermal parameter and control parameter such as supply air temperature and PI control factor are investigated by the thermal chamber cooling test. The results obtained show that the experimental transient temperature behaviors of the space arein good agreement with the simulation results from the multi-zone model.
