STUDIES ON WINTER OPERATION EFFICIENCY OF TABS AND FLOOR BLOW AIR CONDITIONING SYSTEM USING GROUNDWATER AS A HEAT SOURCE/SINK

With the promotion of zero energy in buildings,the use of TABS (Thermo Active Building System), a form of radiant air-conditioning systems, is increasing. A survey on the actual conditions of operation in winter was conducted for the TABS adopted in the S Company’s Hokuriku Branch Office. Data on temperature and flow rate of hot water, as well as power consumption of heat pumps and pumps were obtained every one minute. The purpose of this study is to clarify the application effect to buildings by analyzing the energy consumption efficiency of TABS and floor blow air conditioning system.
