Effects of personal heating on thermal comfort:A review

个性化采暖对热舒适的影响:综述

Personal conditioning system(PCS)is receiving considerable attention due to its energy-saving potential and the ability to satisfy individual comfort requirements.As a part of PCS,personal heating systems can maintain human thermal comfort in cold environments,which leads to their potential role of important heating mode in cold winter,especially in the Hot Summer and Cold Winter regions of China.In order to better promote the development and application of personal heating systems,this paper reviews the published studies.Personal heating systems can be divided into four types based on the mode of heat transfer:conductive,convective,radiative and combinative type.Characteristics of each category and respective devices are introduced.Furthermore,identifying the effects of personal heating on thermal comfort and the models for predicting or evaluating thermal comfort during local heating.This paper would provide users with a guideline for choosing suitable heating equipment during winter.

个性化空调因其同时具备节能潜力和满足个性化热舒适需求的能力而备受关注。作为个性化空调的重要组成,个性化采暖能在寒冷环境中维持人体热舒适,因而具备成为冬季重要采暖方式的潜力。为更好地促进个性化采暖的应用与发展,本文对现有研究成果进行了综述。将个性化采暖按其主要的热量传递方式划分为传导式、对流式、辐射式和组合式四类。总结了各方式的原理、具体形式及特点。比较了主要的三类(传导、对流和辐射)个性化采暖方式对热舒适影响的特点,并将其影响规律定量化。总结和归纳了基于环境参数和生理参数的人体局部热舒适评价模型,同时为用户在冬季选择合适的采暖设备提供了理论依据。
