A whole house fan pulls air out of a building and forces it into the attic space or, in the case of homes without attics, through an opening in the roof or an outside wall. This forces air from the living areas into the attic and out through the gable and/or soffit vents, while at the same time drawing air from the outside into the living areas ...
The most common UFAD configuration consists of a central air handling unit delivering air through a pressurized plenum and into the space through floor diffusers. Other approaches may incorporate fan powered terminal units at the outlets, underfloor ducts, desktop vents or connections to Personal Environmental Control Systems. [8]
These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.
In the event of a fire, this can expose non-fire resistant building materials to heat. A plenum space is a part of a building that can facilitate air circulation for heating and air conditioning systems, by providing pathways for either heated/conditioned or return airflows, usually at greater than atmospheric pressure.
Mechanical ventilation is the intentional fan-driven flow of outdoor air into and/or out from a building. Mechanical ventilation systems may include supply fans (which push outdoor air into a building), exhaust [3] fans (which draw air out of a building and thereby cause equal ventilation flow into a building), or a combination of both (called ...
Part 4 of the Fan Application Manual, reviews the methods of making field measurements for calculating the actual performance of the fan and system. AMCA Publication 801 - Industrial Process/Power Generation Fans: Specification Guidelines provides information on testing and rating power plant fans and covers construction features and related ...
