Orthogonal Experimental of the Factors Influencing Low Temperature Radiant Floor Heating in Hot Summer and Cold Winter Regions
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.
