Example Embodiment

[0054] Example one

[0055] The present application discloses an ultra-low energy consumption building airtight test method. Refer figure 1 and figure 2 The airtight test method of ultra-low energy consumption buildings includes the following steps.

[0056] S1, measurement basic data: measurement test spatial volume and enclosure structure surface area, measurement test space outdoor wind speed, indoor and outdoor temperature, indoor and outdoor air pressure;

[0057] S2, adjust the opening and closing state of the building component: Test the door and window inside the test space to turn on, turn off the doors and windows of the test space and non-test space, and the test space communicate with the non-test space is closed by the blocking device;

[0058] S3, mounting drum door 1: Install the drum damper 1 test system, and seal on the peripheral side of the blast door 1;

[0059] S4, positive pressure test: Test the static pressure of the test space, after the static pressure te...

Example Embodiment

[0080] Example 2

[0081] Refer Figure 10 The difference between the second embodiment of the present application is that the sealing device further includes a support mechanism 7, and the support mechanism 7 is used to support the extrudation ring 42 in the vertical direction, and the support mechanism 7 includes a pad 71 by a bolt. The electric push rod 72 on the plate 71, the push rod end of the electric push rod 72 abuts against the peripheral wall of the extruded ring 42. The support mechanism 7 can support the extrusion ring 42 in the vertical direction, and avoid the effect of blocking cover 2 and the extrudation ring 42 gravity on the annular suction cup 3, so that the annular suction cup 3 is stably sealed in the vicinity of the hole, which is advantageous Improve detection accuracy.

Abstract

The invention discloses an ultra-low energy consumption building air tightness test method. The method comprises the following steps of basic data measurement, building component opening and closing state adjustment, blast door installation, positive pressure test, negative pressure test and important data calculation; wherein the plugging device comprises a plugging cover, an annular suction cup and a pressing mechanism arranged between the plugging cover and the annular suction cup; the plugging cover is used for buckling the peripheral side of the hole; the annular suction cup is made of flexible materials and can deform, one side face of the annular suction cup is attached to the wall on the peripheral side of the hole, and the other side face of the annular suction cup abuts against the end face of the opening end of the plugging cover; and the pressing mechanism is used for driving the plugging cover to abut against the annular suction cup and driving the annular suction cup to be tightly adsorbed to the wall. The wall surface of the building is not easy to damage, the plugging device is easy to disassemble and assemble, detection personnel do not need to tear off the adhesive tape for many times, and the detection efficiency can be improved.

Description

technical field [0001] The application relates to the field of building detection, in particular to an ultra-low energy consumption building airtightness test method. Background technique [0002] In traditional buildings, structural gaps, corners, water pipes and other places are prone to air leakage, which will increase hot air loss, cooling and heating loads, and primary energy consumption. The high tightness of ultra-low energy buildings is one of their main features, which can significantly reduce building energy consumption, ensure indoor temperature and humidity, and reduce noise. Therefore, in order to control the airtightness construction quality of ultra-low energy consumption buildings, it is necessary to conduct airtightness tests after the building is completed. [0003] The Chinese patent with the notification number CN107966254A in the related art proposes a method for detecting indoor air tightness of a residential building, which includes the following step...
