To ensure comfort and efficiency, today’s heating and cooling
equipment must be installed properly. Hot air, heat pumps and
cooling equipment need proper air flow. Too much air and the
system is drafty, humid, and uncomfortable; too little and the
system will not perform properly and the unit will have a
shortened life span.
Ralph Adams from Gray Metal Products will take all the
guesswork out of airflow and duct design. The course will
discuss the importance of proper airflow, pressure drops, static
pressure, blower performance charts, and measuring pressure
drops across different devices.
We will go through a step-by-step process laying out a duct
system including duct length, duct fittings, selecting equipment,
friction rates, and branch sizes. This course is valuable to installers and service personal alike.
