Description

This study ascertained the equilibrium water capacity with circulating hydroflourocarbon R-134a containing a 2% (±1%) 22 ISO-VG polyolester lubricant at 75°F (24°C) and 125°F (52°C) for three prominent desiccants from three manufacturers as mixtures in an equal ratio of 1:1:1. The desiccants were: 1) molecular sieve, 2) alumina beads, and 3) two 100% alumina bonded cores. Isothermal curves were obtained, and a validation of this procedure was performed by producing an isothermal curve of a standard type 3A molecular sieve in R-22 without lubricant at the same test conditions. These data compared favorably with manufacturers’ and published data.
