Analysis of the Regulation Mechanism of Mountain To the Thermal Environment of Embedded Mountain Buildings:A Case Study of Huayan Cave in Chongqing
The mountain resources are not fully utilized in China nowadays,therefore it is of significance to study the concept of embedded mountain buildings that making full use of mountains.Taking Huayan Cave,a typical embedded mountain building in Chongqing,as an example,this paper analyzed the thermal and humid environment in each season of the year by thermal environment measurement,and compared the heat exchange between the indoor walls(including the mountain)and the indoor air,so as to interpret the regulatory mechanism of the mountain on the indoor thermal environment.The results show that,as the mountain is directly used as part of the wall and roof of the building,the embedded mountain building performs well in summer,and the indoor temperature is more stable than in other seasons under the same change of outdoor temperature,but the indoor wet environment is not ideal throughout the year.The stability of mountain temperature throughout the year is greater than that of other indoor walls.For every 1 ℃ increase in outdoor air temperature,mountain temperature only increases by 0.46 ℃.Its adjustment ability to indoor thermal environment is more significant in winter and summer,with the strongest in summer,4.8 times that of the transition season.The ability of the mountain to regulate the indoor thermal environment is closely related to the level of contact with outdoor air.The closer the mountain part is to the ground in summer,the more stable the wall temperature,and the greater the heat absorption intensity.The inner surface heat flow intensity of the mountain foot at the highest room temperature is as high as 50.0 W/m2.
