Systematic reduced scale model experiments were carried out with the aim of relating the geometric configuration of grouped outdoor units to the resultant temperature rise of suction air under stagnant surrounding conditions. Experimental data together with theoretical consideration of a new structure around the outdoor units were summarized into a model equation using two parameters. Observed peak temperature rise of suction air and its spatial distribution were both well reproduced using the prediction method based on the proposed model equation.日本建築学会Journal Articleapplication/pdfhttp://hdl.handle.net/2115/50505https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/50505/1/AIJT.4.65-70.pdf1341-9463AN10531441日本建築学会技術報告集 : journal of architecture and building science465701997-03-20jpn日本建築学会、本文データは学協会の許諾に基づきCiNiiから複製したものであるpublisher
