Abstract

The invention relates to air tightness detection equipment for a blast gate. The air tightness detection equipment comprises a telescopic door frame, a nylon surface cover, a special fan and a control sampling box, wherein the nylon surface cover coves the telescopic door frame; an opening is formed in the nylon surface cover; a circle of tightening belt is stitched on the opening; the special fan sleeves the opening of the nylon surface cover; the tightening belt is tied on a shell of the special fan; the special fan is hung on the telescopic door frame through a pull handle; the special fan is connected with the control sampling box. The air tightness detection equipment is convenient to mount and remove; the measurement structure is accurate, so that the air tightness detection equipment is suitable for being popularized and applied.

Description

technical field [0001] The invention belongs to the field of building performance testing devices, and mainly relates to air-tightness testing equipment for a blower door, in particular to testing equipment for air permeability of building enclosure structures. Background technique [0002] The blast door is mainly used to test the airtightness level of the building envelope, diagnose and demonstrate air infiltration problems, estimate the natural air infiltration rate and the energy efficiency loss caused by air infiltration, and can be used to evaluate the overall performance of the building. In recent years, with the rapid development of my country's construction industry, the airtightness of building envelopes has attracted more and more attention. The international standard "Thermal Performance of Buildings, Determination of Building Air Permeability - Fan Pressurization Method" (ISO9972-2015) clearly requires testing the air permeability of building envelopes.
