In order to study the factors influencing low temperature radiant floor heating in hot summer and cold winter locales,the impacts of five variables-water supply temperature,inter-tube flow rate,tube diameter,tube spacing,and filler layer thickness-on the average temperature and uniformity of the floor surface were examined using the orthogonal test technique of L25(56).The research demonstrates:water supply temperature＞tube spacing＞tube diameter＞filler layer thickness＞inter-tube flow rate has the most influence on the floor surface's average temperature,while tube spacing＞water supply temperature＞filler layer thickness＞tube diameter＞inter-tube flow rate has the most influence on the floor surface's uniformity.The ideal level combination is water supply temperature is taken as 35 ℃,inter-tube flow rate is taken as 0.4 m/s,tube diameter is taken as 16 mm,tube spacing is taken as the test's findings serve as a guide for designing radiant heating systems for use in hot summer and cold winter climates.They also offer suggestions on how to combine statistics and numerical analytic tools.
