Abstract

In this study, a comparison was conducted regarding the comfort range and energy consumption when the indoor set temperature was controlled by WLDC-integrated RCP in two different cases (case 1 and case 2). The objective of this study is to evaluate the feasibility of utilizing this approach by comparing the control performance and energy consumption patterns when the indoor set temperature is increased with the conventional control method. The results showed that the control performance was good in both cases, and there was a significant reduction in electrical energy consumption. However, when operating with the conventional control method, the PMV range was satisfied (-0.5∼+0.5), but when the indoor set temperature was increased, PMV values were slightly higher (0∼+1), indicating the need for a PMV-based control strategy. Furthermore, it was observed that the sensitivity of energy consumption to changes in the indoor setpoint temperature is high, highlighting the necessity for a reevaluation of electrical energy consumption through PMV-based control.
