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

Cooling effects at perimeter zone in autumn fine days

Abstract

PMV control system was applied for a ceiling radiation cooling/heating system utilizing groundwater as heat source/sink. One of our main aims in studying a groundwater-based radiant air-conditioning system is to develop an equipment system and control method that make it possible to maintain a comfortable indoor thermal environment by circulating cold water cooled by heat exchange with groundwater without the need to use a heat pump. This paper describes the effects of the indoor thermal environment and system energy consumption by cooling perimeter zone in autumn fine days.
