Blower Door Test

●Production explanation
The fan pressure test method by the pressure difference method using the blower door. The amount of sedimentation was measured by increasing or decreasing the pressure in the room at intervals of 5 Pa to 10 Pa up to 10 to 50 Pa and it is common practice to estimate the amount of steady-state 4Pa sedimentation based on the results. Also, the indoor and outdoor conditions should be tested under conditions of 0 ~ 2m / s in the meteorological condition and 5 ~ 35 ℃ in the outside temperature according to the ASTM standard, with the condition of the ventilator of kitchen and toilet sealed while measuring

●Configuration
Blower door & fan, pressure measuring device, temperature measuring device, air flow measuring device, wind speed measuring device (optional), etc.
 

●Correlation with Leed
Blower door test uses a high-power fan and air pressure sensor to measure airtight performance of building and identify problems so that it can be repaired to improve energy management of building, reduce indoor air pollution and control indoor environmental levels
The fan uses an enclosed frame to meet customer’s requirements and is mounted on the outside door. The fan blows air out of the building and the pressure sensor measures the room air pressure
The generated pressure difference creates air by penetrating all holes and building envelopes (flowing into inside from the outside). It is usually easy to see and feel where holes and penetrations are. These problems are more likely to be detected than chemical fumes or infrared cameras or simple feelings by hand.
Ideally, there will be, "air conditioned space", some outdoor air flow to prevent mold, backwash, stagnant air, and other stagnant conditions caused by very little airflow wherever in the office or residence.
Test results can be used for the purpose of evaluating indoor air quality and the need for mechanical ventilation, as well as mathematical models for estimating the annual average and designing permeability. It is also helpful to determine the proper size of the heating and cooling system
In testing apartment houses, assuming one thing, and with respect to future LEED certification for homes, LEED established a standard for apartment house airtight performance of 8.1 cm² of leakage space per 9.3 m² of enclosed space. This is equivalent to a smoking area of 0.868 cm² / m² in a building, which is intended for unit-household tabacco smoke control (Environment Tabacco Smoke (ETS) Control).
