一种新型的多孔太阳墙采暖房

长江中下游地区很多建筑没有安装专门的供暖设备,传统的空调采暖增加了建筑能耗。利用太阳能和建筑物自身进行采暖,具有重要的意义和价值。本文提出了一种新型的多孔太阳墙采暖房,其核心部分多孔太阳墙是由多孔陶瓷构成。在晴朗的冬季,对多孔太阳墙采暖房的采暖性能进行了实验研究;研究重点检测了不同外界环境(主要是指太阳辐射照度和环境温度)下,多孔太阳墙采暖房的采暖及储热性能。研究表明:多孔太阳墙采暖房在白天大部分时间都具有较好的采暖效果,且采暖房内的温差较小;同时具有较好的储热性能。以实验测得的武汉地区1月某天的实验数据为例,相比环境温度,当天采暖房内最高温升为19.9℃。在07:00～16:00之间,采暖房的平均温升为11.5℃;在辐射强度较弱的16:00～18:00,采暖房的平均温升为6.6℃。在07:00～18:00之间,采暖房内最大温差为1.37℃,出现在12:40。

A Novel Porous Solar Wall Heating Room

Many cities in the middle and lower reaches of Changjiang River have not installed special heating system,and the traditional air-conditioning heating will increase energy consumption of the building.So it is of great value to make use of solar energy for heating the building.This paper presents a novel kind of solar house—porous solar wall heating room(PSWHR),the core part of which is that the porous solar wall is constituted by the porous ceramic.In this paper,there are some experimental study about heating performance of the PSWHR in the clear winter,the research focuses on heating performance and Thermal energy storage performance of the heating room in different external environment(mainly refers to the solar irradiance and ambient temperature).The results shows that:the PSWHR has a good heating effect during the day,and a small temperature difference in the heating room,PSWHR also has a good heat storage performance.With an example of experiment data on one day in January Wuhan,the maximum temperature rise of the heating room is 19.9℃compared to the ambient temperature.From 7 o’clock to 16 o’clock the average temperature rise of the heating room is 11.5℃.From 16 o’clock to 18 o’clock the average temperature rise of the heating room is only 6.6℃because of weak radiation.During the whole day,the maximum temperature difference in the heating room is 1.37℃in 12:40.
