Webbn may be difficult to quantify. However, interventions should be attempted to reduce recirculation when oxygen delivery is suboptimal and recirculation is suspected. Several techniques, including the use of dual-lumen cannulae, have been successful in minimizing recirculation in venovenous ECMO. This article will provide an overview of the factors … WebbThe zone secondary recirculation fraction Er is determined by the designer based on system configuration. For plenum return systems with secondary recirculation (e.g., fan-powered VAV with plenum return) Er is usually less than 1.0, although values may range from 0.1 to 1.2 depending upon the location of the ventilation zone relative to other …

WebbThe following equation describes this relationship between evaporation, recirculation rate, and temperature change: where: E = evaporation, gpm RR = recirculation rate, gpm DT = cooling range, °F F = evaporation factor The evaporation factor, F, equals 1 when all cooling comes from evaporation. For simplicity, this is often assumed to be the case.
