Method and apparatus for direct heating of a secondary - liquid medium through an air - liquid medium - heat exchanger with hot air as a primary medium

摘要

A method for direct heating of a secondary - liquid medium, in particular heating medium or drinking water, through an air - liquid medium - heat exchanger (10) with hot air, as a primary medium, characterized in that a liquid medium - temperature by controlling a warm air masses current a higher temperature than the value of the liquid medium - temperature and / or by regulation of a liquid medium masses current according to the deviation between a desired value and an actual value of the liquid medium - temperature is set.
