Abstract

A heat pump system having a filter-dryer unit located in the discharge line of the compressor provides unidirectional operation of the filter dryer in a bidirectional system. The relatively high water retention capacity of molecular sieve desiccant at elevated temperatures allows operation of the filter-dryer at the outlet of the compressor while internal baffles in the unit, a specially sized housing and a spring loaded desiccant support structure accommodate the relatively high fluid velocity and other conditions encountered in the discharge line.
