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。
Many buildings in the middle and lower reaches of the Yangtze River do not have any special heating equipment installed. Traditional air-conditioning heating increases building energy consumption. The use of solar energy and building their own heating, has important significance and value. This paper presents a new type of porous solar heating room, the core part of the porous solar wall is composed of porous ceramic. In sunny winter, the heating performance of heating room with porous solar wall was studied experimentally. The research mainly focused on the heating and heat storage performance of heating room with porous solar wall under different external environment (mainly referring to solar irradiance and ambient temperature) . The research shows that the heating room with porous solar wall has a good heating effect most of the day, and the temperature difference in the heating room is small. At the same time, it has better heat storage performance. Taking the experimentally measured data from a day in January in Wuhan as an example, compared with the ambient temperature, the maximum temperature rise in the heating room was 19.9 ℃. Between 07:00 and 16:00, the average temperature rise of the heating room is 11.5 ℃. In the weaker radiation intensity of 16: 00-18: 00, the average temperature rise of the heating room is 6.6 ℃. Between 07:00 and 18:00, the maximum temperature difference in the heating room was 1.37 ° C and appeared at 12:40.
