Sentences with phrase «air leakage openings»

Moisture movement by air leakage (the exfiltration of interior moisture - laden air during heating periods and the infiltration of exterior moisture - laden air during cooling periods) is controlled by limiting air leakage openings, controlling the interior levels of moisture during heating periods by utilizing controlled ventilation (dilution by air change) combined with source control (direct venting of clothes dryers as well as the use of subgrade vapor retarders under concrete floor slabs and bath and kitchen exhaust systems), controlling the interior levels of moisture during cooling periods by utilizing the dehumidification capabilities of mechanical cooling systems, and limiting controlled ventilation to minimum values established by indoor air quality concerns.

In mixed climates, building envelopes are constructed in an airtight manner to control air leakage openings, to expedite air pressure control (depressurization of the building envelope above grade during the heating season, pressurization below grade to control ingress of soil gas and other pollutants, and pressurization of the building envelope during the cooling season) and to facilitate the dehumidification of indoor air during the cooling season, thereby limiting interior moisture levels.

Not exact matches

The management of air starts by pressurizing the MKS cabin and then every opening is scrutinized — every nook and cranny in the car, every hole, every weld, every sheet metal attachment — with the specific thought about where to accept leakage and where to reject it.

Total apartment enclosure air leakage performance was assessed by testing apartments in a fully unguarded configuration, that is, with neighboring apartments open to the exterior.

Supply ventilation will tend to pressurize an interior space relative to the outdoors, causing inside air to be forced out through leakage openings located randomly throughout the building envelope.

Exhaust ventilation systems in all climatic zones draw outside air from leakage openings and pathways located randomly throughout the building envelope; thus, it is not possible to treat the outside air before it enters the living space.

You can also test the total supply duct leakage by isolating the supply side with a cardboard dam on the return opening of the air handler.

Heat waves lead to warmer indoor temperatures in three primary ways: conduction of heat from outdoors through the building envelope; transmission of radiant solar heat through windows; and the convection of warm air through open windows and doors and air leakage.

These homes feature open - cell spray foam insulation that reduces air leakage and allows for smaller - sized HVAC units.
