Abstract

Abstract: Suspended kang and landed kang are two types of heating device used popularly in northern China in winter currently. Their structure and sealing performance have an obvious influence on the indoor thermal environment and indoor air quality. Referring to relevant National Standards, a continuous comparative experimental investigation of indoor thermal environment and air quality of heating with those two kinds of kangs was conducted in county Lintao, Gansu. The result showed that the indoor daily mean temperature of heating with suspended kang would be 12.6 ℃, being 1.8 ℃ higher than that of heating with landed kang (10.8 ℃). It was found by employing PMV-PPD index evaluation that the comprehensive evaluation grade of indoor thermal comfortableness would be class-Ⅱ for the suspended kang, and that of landed kang would be class-Ⅲ. Indoor air quality PM_2.5, PM₁₀ and CO index of heating with suspended kang would be superior to that of landed kang, the indoor primary pollutant of heating with both types of kang would be PM₁₀. The indoor air quality grade of heating with suspended kang would be pollution, the indoor air quality grade of heating with landed kang would be heavy pollution.

Key words: landed kang, suspended kang, indoor thermal environment, indoor air quality, indoor comfortableness
