C. Aprea et al., A criterion for predicting the possible advantage of adopting a suction/liquid heat exchanger in refrigerating system, APPL TH ENG, 19(4), 1999, pp. 329-336
An analysis for evaluating the possible advantage of adopting a suction/liq
uid heat exchanger, from a thermodynamic point of view, is carried out. To
this purpose, a simplified criterion is prented; this is also validated for
many working fluids such as chlorofluorocarbon (CFC)s, hydrochlorofluoroca
rbon (HCFC)s and substitutes on the basis of their thermodynamic properties
available in scientific and commercial literature. The criterion is also p
resented in a graphical form and two examples, referred to as R502 and R32,
are given. (C) 1998 Elsevier Science Ltd. All rights reserved.
