Study on characterization of typical thermal environment for ground local radiant heating
Local fine heating is one of the important ways to reduce heating energy consumption and realize efficient utilization of heating energy under the premise of satisfying the comfort of indoor personnel.In order to improve heating efficiency and provide a method reference for refined radiation heating,the office space with significant station layout requirements is selected as the object in this study to conduct typical research and analysis on the distribution of thermal environment in different indoor areas under the influence of ground local radiation heating modules,and the distribution characteristics of indoor non-uniform thermal environment under different local module heating conditions are obtained.The analysis results show that when the local radiation area is 16.7％,the average radiation temperature difference between the radiation area and the non-radiation area is more than 3 ℃,which has obvious local environment construction effect.There is a significant difference in the asymmetric radiation temperature between the radiation area and the non-radiation area of the ground local radiation heating.Setting the local radiation source near the outer wall area can increase the overall average radiation temperature and make the indoor average radiation temperature distribution more uniform.This study gives a preliminary description of the common characteristics of typical thermal environment based on ground local radiant heating,which can provide a reference for the fine design of subsequent local radiant heating systems.
