| Research Abstract |
(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.
