[EN 13141-7:2021, 3.11]pressure increase induced by the ventilation unit given as difference between the static pressure at the unit outlet and the total pressure at the unit inlet.Note 1 to entry: The parameter pus for a ventilation unit is defined … Continue reading →
[AIVC, Air infiltration and ventilation glossary, 1992]:a method of testing air leakage of a building or component by installing a fan in the building envelope, for example through a door or window, and creating a static pressure excess inside the … Continue reading →
[AIVC, Air infiltration and ventilation glossary, 1992]:this technique allows building airtightness to be examined at small ( Pa) pressure differentials with minimal interference from climatic forces. Tue air flow through the building envelope can be evaluated by using a piston … Continue reading →
[AIVC, Air infiltration and ventilation glossary, 1992]:a measurement technique using two or more blower doors to evaluate the leakage of individual internal partitions and external walls of multizone buildings. The technique involves using the fans to induce a zero pressure … Continue reading →
[AIVC, Air infiltration and ventilation glossary, 1992]:building airtightness levels can be measured by using a fan, temporarily installed in the building envelope (a blower door) to pressurize the building. Air flow through the fan creates an internal, uniform, static pressure … Continue reading →
