人体火积平衡模型的建立及火积耗散特性
Establishment of human body entransy balance model and entransy dissipation characteristics
摘要
Abstract
The human body is an open thermal system.Many scholars put forward human body energy balance model to analyze the heat exchange process between the human body and the in-door thermal environment.However,due to the loss in the heat exchange process,some scholars established human body exergy balance model and conducted related research.Exergy emphasizes the ability to do work,while entransy emphasizes the ability to transfer heat;therefore entransy is more suitable for studying the heat transfer or exchange between human body and thermal en-vironment.Based on Gagge's two-node human thermal balance model and the definition of entran-sy,this paper establishes the human entransy balance model,deduces the calculation formula of human entransy dissipation,and analyzes the influence of indoor thermal environment parameters on human entransy dissipation.The results show that when the air relative humidity is 30%～70%,the human entransy dissipation first decreases and then increases with the increase of air temperature and average radiation temperature,and air temperature and average radiation temper-ature have great influence on the entransy dissipation of human body.When the air temperature and average radiation temperature are 20～30℃,the human body entransy dissipation decreases with the increase of air relative humidity.When the air temperature and the average radiation temperature are both less than 25℃,the change of air relative humidity has little influence on the entransy dissipation of human body.关键词
