Abstract
In a printing system disclosed in the present invention, part of warm air supplied from a supply port of a drying unit is supplied from an exhaust gas inlet through exhaust ducts to a sensible heat exchanger, and is ejected from an exhaust gas outlet of the heat exchanger. The air ejected from the exhaust gas outlet enters from an outside air inlet through a first outside air duct, and heat thereof is exchanged with heat of outdoor air ejected outdoors from an outside air outlet through a second outside air duct. Air subjected to heat exchange and cooling is supplied through exhaust ducts to a first air intake port and a second air intake port of the drying unit. Accordingly, part of the warm air supplied from the drying unit to web paper undergoes heat exchange and is reused, achieving reduction in amount of indoor air taken into the drying unit. This results in reduced burden on an air conditioner system.
