Working with the outdoor characteristics of 35 o C db, and 24 o C wb and indoor variables of 18 o C db, the analysis yielded a sensible heat ratio of 0.6966, and cooling capacity of 440 W. In this paper, a psychrometric analysis of an airconditioning system operating under given ambient conditions was undertaken. Thus, both dehumidification and cooling can be obtained with a cooling coil effective surface temperature lower than the dew point temperature of the entering air. This separation of the moisture results in fall in the specific humidity or humidity ratio. When air passes over a cooling coil whose effective surface temperature is below the dew point temperature of entering air, condensation of the moisture takes place. When the relative humidity has no sense, the humidity ratio is taken as entrance parameter within a range from 0 to 500 g/kg dry air, selected in accordance with the industrial experience of the authors considered as most appropriate. The heading of the table presents the used letter symbols and nomenclature in accordance with the one used by ASHRAE/2/. This original way to show data of moist air is very practical and will probably be used by other authors in the future. Second entry can be the temperature of dry bulb and third the relative humidity with intervals of 5% (or humidity ratio with intervals of 25 g/kg dry air).

First entry shown below with full details referring to pressure, altitude, and unit systems. The details are shown on tables with three entries. The selected range covers the pressures and temperatures in the use of transport of air by fans and useful atmospheric data in mines and places up to 5000 m height with pressures between 0,54 and 1,35 bar and temperatures between-50 and 350☌ with intervals of 1☌ to boiling temperature and 5☌ from then upwards. The thermodynamic and psychrometric properties of moist air selected cover amply the requirements for industrial application now and the ones expected in the near future. The purpose was to find out the approximate grade mentioned by Hyland & Wexler/3/ authors of recognized prestige in this area. The object of the work consists in obtaining the properties of moist air in a wide range of industrial utilization including applications such as driers and transport by fans. The present communication resumes the contents of an investigation project sponsored by the BASQUE COUNTRY UNIVERSITY.
