Abstract

Thermal comfort is the condition of mind that expresses satisfaction with complex thermal factors. Mostly, human thermal comfort depends on four environmental parameters and two personal parameters. This paper proposes an example, especially in typical summer clothing during sedentary and moderate activity at mean air velocity, that the slope of the effective temperature line as thermal comfort level, which is composed of air temperature and relative humidity, is defined. Not only were we interested in thermal comfort of room, but also energy saving. This paper also proposes a least enthalpy estimator (LEE) that combines the definition of thermal comfort level and the theory of enthalpy into a load predicting way to search suitable a temperature and relative humidity setting. Due to the change of humidity in the space, the temperature will be revised reversely toward a new setting. It is helpful to keep on the thermal comfort level and to determine the proper settings opportunely for HVAC control system with LEE.
