EXPERIMENTAL STUDY ON THE PMV CONTROL OF CEILING RADIATION COOLING/HEATING SYSTEM USING GROUNDWATER

Thermal environment and system energy consumption under radiation and convection air-conditioning, and continuation and intermittent operation conditions

Abstract

PMV control system was applied for a ceiling radiation cooling/heating system utilizing groundwater as heat source/sink. The purpose of this study is to clarify that the power consumption of this radiation air-conditioning system is small as compared with convection air-conditioning system. Through the experiments of summer and winter seasons, the power consumption of the radiation system dropped to 50% of the convection system in summer and dropped to 65% in winter without power consumption of a makeup air unit.
