pressure, unit

[EN 13141-7:2021, 3.10]pressure increase induced by the ventilation unit given as difference between the total pressures at the unit outlet and the unit inlet.Note 1 to entry: In case of equal cross-section areas of the inlet and outlet, the total Continue reading →

pressure, unit static

[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 →

pressurization

[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 →

pressurization, AC technique

[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 →

pressurization, balanced fan

[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 →
