    • Abstract
  • Although it is cold in winter and hot in summer, the south Jiangxi region is classified as non-heating zone, where indoor thermal comfort is poor in winter.Due to various reasons, the demands for comfort living environment are growing, which leads to an urgent need to improve the indoor environment.Given the features of climate and geography in south Jiangxi area, the effect of low temperature floor radiant heating was researched and compared with that of heating of the air conditioning.Numerical simulations under two kinds of heating means for thermal environment in the heating room using CFD software were conducted to analyze air temperature field and humidity field.Indoor thermal environment was used by the PMV-PPD to evaluate index.The results show that compared with air conditioning, low temperature floor radiant heating is more comfortable with indoor design temperature reducing 2~3℃, and energy saving of 15%, which is beneficial to energy conservation and environmental protection.
