Abstract

The purpose of this paper is to improve the performance of the HOT WATER FLOOR-HEATING SYSTEM WITH HEAT PIPE by solving the problems suggested in the previous paper. The problems were uneven temperature of the floor surface and slow temperature rising. THERMO-UNIFORMITY PLATE were developed to solve the problems. Effect of this member was verified in the artificial climate room. The results are as follows; Because of improvement of THERMO-UNIFORMITY PLATE from plywood covered with aluminum foil to Aluminum extrusion panel, 1) The heat transfer from pipe to THERMO-UNIFORMITY PLATE was promoted extremely. 2) Heating performance can be improved by about 30 %. 3) Accordingly uneven temperature and rising speed of temperature of floor surface were improved.
