L. Bellia et al., Cooling energy consumption and operating costs: evaporative all-air and air-and-water systems in the Italian climate, INT J ENERG, 24(2), 2000, pp. 163-175
The economic analysis for running two kinds of hybrid air conditioning syst
ems: all-air and air-and-water, both with add-on evaporative cooling stages
, is studied in this paper. Single-duct, single-zone, constant volume syste
ms are dealt with. Processing the climatic data of the European 'test refer
ence year-TRY for Italy, a comparison of such systems' performance versus t
he relative traditional one is performed. Energy consumption and operating
costs are evaluated by an appropriate computer code written with the aim of
: (i) making plain the input/output of data; and (ii) displaying very frien
dly software masks as well as useful graphical elaboration. On the basis of
outdoor air state, calculations are performed according to two different p
rocedures: (a) hourly, following the TRY profile; and (b) for each bin, 1 d
egrees C wide, in which the simultaneous dry- and wet-bulb temperatures fal
