Specifying and designing gasketed plate heat exchangers
Approach temperature, pressure drop and wall shear stress in HVAC service
A technical seminar for consulting engineers on how gasketed plate-and-frame heat exchangers are built and how the numbers in a specification drive their size, cost and service life. It covers the energy balance, log mean temperature difference and thermal duty, Reynolds number and the Darcy-Weisbach pressure drop, maldistribution, why added fouling factors work against plate exchangers, wall shear stress and part-load operation, port filters and backflush valves for open loops, and certification of liquid-to-liquid heat exchangers to AHRI Standard 400.
