Abstract

A gas dehumidification device having two heat exchangers, each including a first and second fluid line. Each second fluid line at least partially surrounds the respective first fluid line. Each heat exchanger thermally couples a fluid in the respective heat exchanger second fluid line with a first coolant on an outside surface of the respective heat exchanger second fluid line. The gas dehumidification device further comprises a two-position valve. In a first position, a fluid comprising a higher temperature than the first and/or second coolant is conducted into the first heat exchanger first fluid line and in the second position, the fluid is conducted into the second heat exchanger first fluid line. A controller is configured to place the valve selectively into the first or second position.
