Abstract
A refrigerant dryer, in particular a compressed air refrigerant dryer, is provided for drying a gaseous fluid while cooling the gaseous fluid using a refrigerant. The dryer includes a pressure fluid-refrigerant agent-heat exchanger () in which a cooling of the gaseous fluid takes place directly or indirectly by a refrigerant conveyed in a primary loop (), one or more refrigerant compressor/compressors () for operating the primary loop, and a cold accumulator () with an accumulator-side heat exchanger () which couples an accumulator discharge fluid to a cold accumulator medium (). The pressure fluid-refrigerant agent-heat exchanger () and the cold accumulator () are fluidically connected or can be brought into fluidic connection via a discharge loop () for an accumulator discharge fluid. The cold accumulator () is arranged, relative to gravity, above the pressure fluid-refrigerant agent-heat exchanger (), in such a manner that the heated accumulator discharge fluid is conveyed through the discharge loop () for cooling in the cold accumulator (), is cooled there, and subsequently re-conveyed to the pressure fluid-refrigerant agent-heat exchanger ().
