It was a difficult time for close dialogs and exchange of information, but still it happened that three men, nearly in the same time, made the same contribution to the science and art of HVAC & R: namely, Carrier in USA, Ramzin in Russia, and Mollier in Germany.

It is interesting that three men got the same idea in three very different locations of the globe, at a time when there were no radios, good phones, or electronic connections. = Cpu/k, Nres = d.The psychrometric diagram, or diagram of humid air, was established by three authors in a period of 12 years, very possibly independently from one another. the total mass of moisture evaporated at the end of drying in one batch. the mass of wet silica gel particles that can be dried in one batch if the dryer contains 3 trays, g. The drying-rate flux, R, for the falling-rate period can be expressed as a parabolic function of moisture content, X, as, R = 16X + 235X2 e. the drying time for the falling-rate period in hours. the drying-rate flux for the constant-rate period, the drying time for the constant-rate period in hours, d. If drying will take place from the top surface only and bone-dry density of silica gel is 750 kg/mº, calculate a. The critical free-moisture content of particles is found as 10% (dry basis) based on the experiments done under these drying conditions, after which a transition to the falling rate period occurs. It flows parallel to the top surface of the trays at a velocity of 3.8 m/s. Hot air at 1 atm is used as a heating medium with a relative humidity of 4% and an absolute humidity of 0.053 kg H2O/kg dry air.

For this purpose, the trays, having the dimensions of 0.5 m (length) 0.5 m (width) x 0.03 m (depth), are completely filled by wet particles. The final free-moisture content of 1% is desired at the end of drying process. When silica gel particles reached moisture saturation (a free-moisture content of 37% (dry basis)), they can be reused by drying the particles in a batch wise tray dryer. Silica gel (encountered in everyday life as beads in a small paper packet) is used as a desiccant to protect leather, electronics, and food from moisture. 330 340 OSE 360 370 380 390 400 Carrier 60 79 08 90 10 PSYCHROMETRIC CHART NA HIGH TEMPERATURES SI METRIC UNITS Barometric Pressure 1,320 SEA LEVEL HA NI 0.09 OŻE.
