A compressor system for compressing gases in a multistage compression includes a next-to-last compressor in a flow direction and a last compressor which are connected in series, one or more intercoolers between the next-to-last compressor and the last compressor, and an adsorption dryer connected downstream of the last compressor and designed as a rotation dryer having a rotating adsorption chamber. An inside of the adsorption chamber includes a regeneration sector and a drying sector. The regeneration sector is connected to the last compressor such that the compressed gas stream output from the last compressor is guided in a full stream principle through the regeneration sector. A bypass line which bypasses the intercoolers is situated between next-to-last compressor and last compressor, and includes a setting element to set the gas stream guided via the bypass line and therefore the regeneration entry temperature of the compressed gas in the regeneration sector appropriately.

Intercooler bypass

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

In a method for operating an adsorption device to remove at least in part an adsorbable and/or condensable component from a gas flow. The adsorption device contains an adsorption material and is configured in such a way that the adsorption material is brought into contact with the gas flow in an operating region and can be regenerated in a regeneration region. In the case of an at least temporary interruption or discontinuation of transportation of the gas flow to provide an output gas flow, a follow-up operating phase is initiated, during which a portion of the adsorption material is moved out of the regeneration region.

Method for operating an adsorption device and a control unit

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 ().

Refrigerant dryer

An adsorption drying apparatus, in particular for drying a compressed gas, includes an adsorption chamber () having a plurality of adsorption conduits () containing an adsorption material (), a first feeding line () and a first discharging line () disposed at a first end () of the adsorption chamber (), and a second feeding line () and a second discharging line () disposed at a second end () of the adsorption chamber (). The adsorption chamber () is rotatable with respect to the feeding and discharging lines () so that the adsorption conduits may be fluidically connected in temporal alternation, wherein the gas is dried in a drying sector (), and the adsorption material () is regenerated in the regeneration sector (). The first feeding line () is configured such that the gas stream to be dried may be fed to the regeneration sector () as a full flow.
