Potential of sloped solar chimney for the architectural development of sustainable applied technology models for passive air ventilation
Sugini1, Etik Mufida2, Risdiyono3.
This paper presents the result of research section for solar chimney (SC) model innovation as a passive cooling strategy. The research is motivated by sustainability issues, especially on the issue of environmental degradation due to uncontrolled use of air conditioning in urban environments. The vertical SC (VSC) model has been tested by the author et al., 2018. Although in general the presence of VSC has a significant effect on room temperature but it turns out that the VSC column height, that is assumed as the main determinant of performance, does not significantly influence [1]. The character of sun altitude in Indonesia is believed to cause the vertical chimney to be ineffective. For this reason, this study tested the Sloped Solar Chimney (SSC) model. The purpose of this study is to test whether: (1) SSC is better than VSC; (2) the sloping chimney thickness and internal chimney height give a difference in SC performance. The SSC model consists of three components: (1) internal vertical chimney inlet; (2) External 30⁰ slope and (3) external outlets. The test model is made from galvalum. Overall, the research method was carried out in two stages, namely: (1) testing the simulative models by using a software based on empirical data on the context of the urban housing environment being sampled; (2) testing the models in the field. However, only the result of the first stage is presented in this paper. The location of the urban environment of dense housing used as a case study was Jogoyudan, Yogyakarta. The empirical data input consists of 3 groups of houses: on the banks of the river, in the middle of a dense housing and on the edge of a neighborhood road. The modeling software used is CFD analysis. The analysis uses a comparative test statistic with a confidence level of 5%. From the results of the study it is found that SSC caused different thermal qualities in the test model room. The thickness of the sloping chimney also gives a difference in the thermal quality of space. However, this phase of the research has not been able to show significant effects due to the differences in height of the internal chimney.
