Indoor Temperature Control System of Accumulation Electric Ondol Using Fluid Control

摘要

PURPOSE: An indoor temperature control system is provided to prevent excessive heat radiation during an early stage and maintain indoor temperature constant, while improving utilization of accumulated heat. CONSTITUTION: An indoor temperature control system comprises a heat radiation layer(2), an upper heat insulating layer(3a), a heat accumulating material(5) equipped with an electric heater(4); a lower heat insulating layer(3b); a damp course(7); a bottom layer(8); a supply pipe(9) interposed between the heat radiation layer and the upper heat insulating layer, and branched off into a heat accumulating pipe(10) passing through the heat accumulating material and a bypass pipe(11) passing underneath the bottom layer; and a three-way automatic control valve(13) arranged at the confluence of the heat accumulating pipe and the bypass pipe, and connected to a temperature sensor(12).
