AN AIR-CONDITIONING CONTROL METHOD FOR BUILDING PERIMETER ZONE USING MEASURED SKIN-LOAD

Abstract

This paper describes the principle of a new control method, called skin-load control, for perimeter zone air-conditioning of a large area office, and examines the characteristics and the installation methods of a radiation temperature sensor, which is a key component of the system. The paper underlines the importance of the convective heat transfer coefficient in skin-load control and explains how to identify it. The paper also shows that skin-load control is excellent for both control and energy conservation by examining the perimeter zone's thermal environment. The experiment results showed that it was not possible to adequately control perimeter air temperature using the conventional control method, because since it involved an open control loop.
