The invention relates to a heat exchanger for a refrigerant dryer such as a compressed air refrigerant dryer comprising at least one first inflow surface element, past which a fluid to be dried such as compressed air can flow during operation of the heat exchanger, and comprising at least one second inflow surface element, past which a refrigerant fluid can flow as required during operation of the heat exchanger, wherein the first and second inflow surface elements are or can be coupled at least in some areas to at least one cold store chamber that is provided for filling with a cold accumulator medium, and wherein the first and/or second inflow surface element(s) (is) are connected to at least one heat transfer element which extends into the cold store chamber, e.g. penetrates the cold store chamber.

Refrigerant dryer, in particular compressed air refrigerant dryer, and heat exchanger for a refrigerant dryer, in particular a compressed air refrigerant dryer

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 ().
