Abstract
Abstract A refrigeration system is equipped with at least two absorbers, a heater for regenerating the absorbent material in each absorber, a condenser and collector vessel associated with each absorber, and a common evaporator. Valves connect the absorbers, condensers, collectors, and the evaporator, and are interlocked with each other and the switches for the electrically operated heaters to permit three modes of operation. In the first mode, the absorbers are cyclically and alternatingly discharged to provide refrigeration and heated for regeneration. In the second mode, all absorbers are being discharged simultaneously, and they are being regenerated simultaneously in the third mode. The necessary actuating system is set by shifting a single control member.
