干式地板辐射供暖系统特性的试验研究
Experimental Study on Performance of Lightweight Radiant Floor Heating System
摘要
Abstract
In order to get a better knowledge of Lightweight radiant floor heating ( LRFH) system,thermal performance and thermal comfort are analyzed.The study results indicate that LRFH system shows fine thermal stability and thermal comfort with u-niform indoor air temperature distribution both in horizontal and vertical directions.When the system reaches stable condition,ra-diant heat transfer accounts for 65.6%of total and the total heat transfer can meet heating demand of most buildings.The indoor air temperature of the LRFH system is obviously changed when the supply water temperature is changed in the range of 35 ~40℃,while the water flow has little influence on it.Compared with heavy radiant floor heating (HRFH) system,it has shorter preheating time,lower temperature requirement of supply water and stronger heating capability,but the heat storage capacity is poor.Results will provide technological foundation for design and application of LRFH system.关键词
