COOLING-RANKINE ABSORPTION CYCLES. PART TWO: MULTIEFFECT WORKING/COOLING CYCLES-SENSIBLE HEAT SUPPLY CASE

摘要

MeW/CC basic rules, model and main MeW/CC supplied by sensible heat supply, types, plotts, efficiencyand effectiveness are tabulary presented. As compared to NH3  H2O single-stage cooling CRAC, MeW/CCdouble- and treble-effect working increases by (9.5-11.1)% and (12.0-14.0)%, for heat/sink source anddesorber temperatures of T_(h,ss) = 250°C/T_(M,c) = 32°C/22°C/12°Cand T_(DI) = -27°C/-43°C/-58.5°C  respectively. An extention of model results up to T_(h,ss) = 330°C is shown. The use of rectificationlessworking combinations (e.g. H_2O - LiBr, NH_3 - NaSCN, NH_3 -LiNO_3 ) with high critical point refrigerantsis beneficial for MeW/CC working and cooling separate and combined yield.
