Field study on indoor thermal environment and human thermal comfort in office buildings with different heating terminals
To determine whether the indoor thermal environment parameters in office buildings under radiant and convection heating modes in the cold climate zone can meet the requirements of human thermal comfort,this study selects the office buildings with different heating modes in Xi'an as the research object,and carries out indoor physical environment tests and human thermal comfort subjective questionnaires,and 1120 valid survey questionnaires are collected during the investigation.The results show that the indoor air temperature and vertical temperature difference under the convection heating mode are significantly higher than those under the radiant heating mode,and there is overheating in the room.The neutral temperatures of radiant and convection heating are 17.4 ℃ and 20.4 ℃,respectively.The higher indoor air temperature forms a higher neutral temperature and an upper limit of acceptable temperature.
