Method for drying laundry, and a drying cabinet for carrying out such method

A method of drying flat material hanging downwardly in a cabinet wherein heated air is discharged from a first vertical side wall into the interior space of the cabinet for exhaust from an opposite vertical side wall of the cabinet, said method comprising the steps of:

• introducing the heated drying air from said first wall against edges of the vertically hanging flat material,
• flowing the air in said interior space with a primary flow from above to below and transversely from said first side wall toward said second side wall for exhausting at a lower portion of said second wall, causing a minor flow of air transversely across and for exhausting at the upper portion of the cabinet, directing the heated moist air exhausting from the interior of said cabinet to a heat exchanger, passing inlet fresh air into said heat exchanger for being heated by said heated exhausting air from said cabinet interior to provide preheated air, and passing the preheated air to a heater for further heating the drying air, and then passing the drying air to said first cabinet wall for discharge into the cabinet interior.
