Abstract
The purpose of this study is to develop a supply air dew point temperature control of a desiccant air-conditioning system for low-humidity environments. To develop the control, we need to know the basic characteristics of the desiccant air conditioning system, which is a controlled system. In this paper, we construct a mathematical model and analyze systematically the basic characteristics of the controlled system. Specifically, we investigate the static and dynamic characteristics of the controlled system with respect to manipulated variables such as desiccant-wheel rotary speed and regeneration outside air flow rate. For static characteristics, we investigate the relation between controlled and manipulated variables and examine the influence of manipulated variables on controlled variables. For dynamic characteristics, we investigate the step response of controlled variables and examine the responsivity or overshoot of controlled variables.
