Pilot plant study for effective heat transfer area of coiled flow inverter

摘要: Abstract Three new coiled flow inverter (CFI) heat exchangers with transfer area ( A t ) of 0.88 m 2 (4-banks), 0.44 m (2-banks) and 0.22 m (1-bank) were designed, fabricated commissioned to develop a more compact exchanger. More than 800 experiments carried-out in counter-flow configuration. The hot cold fluids used the tube shell side CFI exchanger, respectively. Tube rates varied from 50–300 kg/h for water 30–100 kg/h compressed air, 100–2000 kg/h 400–750 kg/h overall coefficients present found good agreement results reported  = 1.76 m . proposed exchanger  = 0.22 m provides 2.2–4.5 2–3.6 times higher coefficient as compared SHE PHE , study offers small footprint meet same duty previously study.
