AIRTIGHT EXPERIMENT METHOD AND AIRTIGHT EXPERIMENTAL EQUIPMENT THEREOF

摘要

PROBLEM TO BE SOLVED: To reduce the cost because airtight experimental equipment is comparatively simple, since the airtight of an aperture structure of a building is measured, corresponding to the actual construction environment of the aperture structure of the building, and the experimental result thus obtained has credibility and representativeness.;SOLUTION: The airtight experiment comprises steps, wherein the aperture structure of the building is offered first, the aperture structure of the building is prepared in the building structure; then a sealing structure, corresponding to the aperture structure of the building, is provided, the building aperture structure and the sealing structure constitute a chamber. Furthermore, a pressure supply unit which carries out communication with the chamber is provided. A pressure difference is provided to the chamber, by the pressure supply unit. Finally, by measuring the flow rate between the pressure supply unit and the chamber, airtightness of the building aperture structure is decided.;COPYRIGHT: (C)2008,JPO&INPIT
