PURPOSE: A Korean floor heating panel for cooling and heating is provided to respectively install couplers at the inlet and the outlet of a heat transfer pipe, and to block a flow groove using a ball with spring pressure generated by removing an external force, thereby preventing the leakage of a fluid. CONSTITUTION: A Korean floor heating panel for cooling and heating comprises boards having unit sizes, and the board is formed by sequentially laminating an outer sheet layer (310), a space layer (320), and a heat transfer layer (330). A heat transfer pipe (331) is placed in the heat transfer layer in zigzags, and auxiliary pipes (331c) are respectively connected to one side of an inlet (331a) and an outlet (331b) thereof. Three-way valves (335) are respectively installed at the inlet and the outlet, and are connected to an adjusting bolts (337) exposed to outside the board. The heat transfer pipe has couplers (339) at the inlet and the outlet thereof, and the couplers respectively have flow grooves in which a fluid flows when balls elastically supported by springs move. |
