Study on the indoor thermal comfort under the condition of the ceiling and floor radiant cooling
摘要
Abstract
Study of indoor thermal comfort under the condition of the ceiling and floor can provide the oretical basis for opitirnizing the cooling system and meeting the human body thermal comfort.This paper expounds the two types of radiation cooling mode for ceiling radiant cooling and floor radiant cooling,and their radiant cooling mechanism, analyzes the factors affecting the indoor thermal comfort.Taking experiment room applied of radiant cooling air conditioning technology as the research object,this paper builds simulation model of the room using Airpak,makes numerical simulation and contrastively analysis of the effect on the indoor thermal comfort for the two types of radiation cooling mode for ceiling radiant cooling and floor radiant cooling in three aspects of indoor vertical temperature difference,PMV-PPD index and draft sensation.The results show that along the height direction of the room,the vertical temperature difference of roof radiant cooling is less than 3 ℃.But that of roof radiant cooling is too much,local thermal comfort requirements can't be met well;PMV value of the ceiling radiant cooling is fundamentally in -0.5 ~ +0.5,the human body is closest to the best state of thermal comfort.But the floor radiant cooling only guarantees satisfactory PMV value around human body.When considering draft sensate,disapproval rating PD of two cooling patterns are less than 15%,which can meet the requirements of the human body for the thermal comfort of the hair dryer.关键词
