VERIFICATION OF CALCULATION ACCURACY OF MULTIZONE AIR FLOW MODELS (COMIS MODELS) USING A FULL SCALE TEST HOUSE

对东北大学校园被动式太阳能系统性能研究试验室的围护结构构件的漏风面积分别进行了测量，并对用于多区入渗研究的临时内隔断的漏风面积进行了测量。(2)利用试验室进行空气入渗速率的长期试验对于单室，采用示踪气体CO_2的恒定发射法测量空气入渗；对于三室，采用NO_2、SF_6和CHCl_2F三种示踪气体的衰减法测量空气入渗。试验在不同的室内外温差和风速条件下进行。研究了温差和风速对空气入渗速率的影响。(3)大气入渗模型计算精度的验证与国外研究组开展了大气入渗模型（COMIS）的联合研究。通过空气入渗速率测量数据对COMIS代码进行了验证。(4)结合热性能模型的气流模型检验将多区气流模型与热负荷模型相结合。改变参数变量，进行含多区空气入渗的热负荷计算。(5)研究成果的发表上述研究成果已在国际能源署组织的国际学术研讨会上发表，并将在日本建筑学会东北分会会议上发表。

(1)MEASUREMENT OF AIR TIGHTNESS PERFORMANCE OF THE A HOUSE The air leakage areas of the envelope components of the test house, which was constructed for research on passive solar system performance at the campus of Tohoku University, was measured respecively, and the air leakage areas of the temporary internal partition for multizone infiltration research also was measured.(2) A LONG-TERM TEST OF AIR INFILTRATION RATE USING THE TEST HOUSE For single-room, the constant emission method with the tracer gas CO_2, is applied for measurement of air infiltration, For three-room, the decay method with three tracer gases, NO_2, SF_6, and CHCl_2F, is employed. The test was carried out under various conditions of indoor-outdoor temperature difference and wind speed. The effect of temperature difference and wind speed on air infiltration rate was investigated.(3) VERIFICATION OF CALCULATION ACCURACY OF AIR INFILTRATION MODELS The co-research of Air Infiltration Model (COMIS Models) with research groups of foreign countries was carried out. The code of COMIS was verified by the data of measurement of air infiltration rate.(4) EXAMINATION OF AIR FLOW MODELS COMBINED WITH THERMAL PERFORMANCE MODEL The multizone air flow models were combined with models of heat load. The variables of parameters were changed and the calculation of heat load including multizone air infiltration was carried out.(5) PUBLICATION OF RESEARCH RESULTS The mentioned above research results were reported in international symposium organized by IEA and will be reported at Tohoku branch meeting of Architectural Institute of Japan.
