Heat and mass transfer in a bubble plate absorber with NH3/LiNO3 and NH3/(LiNO3 + H2O) mixtures

Performance of Different Experimental Absorber Designs in Absorption Heat Pump Cycle Technologies: A Review

“…Figure 4 shows the bubble absorber configuration. Oronel et al [37] evaluated the heat and mass transfer coefficients in a bubble plate absorber operated with NH 3 /LiNO 3 and NH 3 /(LiNO 3 -H 2 O) mixtures. The absorber used was a corrugated plate heat exchanger with Chevron-L type corrugation (30° from the plate vertical axis) with 0.1 m 2 heat transfer area.…”

Flow boiling and frictional pressure gradients in plate heat exchangers. Part 1: Review and experimental database

“…In still other studies, the boiling characteristics of several other solutions and binary mixtures in PHEs were evaluated for LiBr -H 2 O and NH 3 -H 2 O by Garcia-Hernandoa et al (2011b), NH 3 -LiNO 3 and NH 3 -NaSCN solutions by Cerezo et al (2011a), NH 3 -LiNO 3 and NH 3 -(LiNO 3 + H 2 O) by Oronel et al (2013a) and etrabutylammonium bromide (TBAB) -clathrate hydrate slurry (CHS) as a secondary refrigerant in an air conditioning system by Ma and Zhang (2011c). Other work in the literature on plate evaporators is exemplified by several other researchers: Kedzierski, Garcia-Cascales et al, Qiao et al (2007aQiao et al ( , 1997aQiao et al ( , 2013b.…”

Visual experimental research on the effect of nozzle orifice structure on R124–DMAC absorption process in a vertical bubble tube

“…For the plate-type absorber, the effect of key parameters on ammonia-water bubble absorption performance was studied by visual experiment (Kang et al, 2002a(Kang et al, , 2002b and by modeled analysis (Cerezo et al, 2009;Lee et al, 2002Lee et al, , 2003Oronel et al, 2013;Terasaka et al, 2002). It was found by researches that the key parameters are the refrigerant vapor flow rate, absorption solution flow rate, temperature and concentration, operation pressures, cooling medium temperature and flow rate, nozzle orifice diameter and number.…”
