The invention relates to a room temperature drying system, mainly comprising: an inner drying chamber, an outer chamber with temperature difference, more than one dry article trolleys placed in the inner drying chamber, an air-conditioning device set on the wall in the outer chamber with temperature difference. The temperature of the inner drying chamber is controlled by the air-conditioning device at 2 degrees Celsius higher than that of the outer chamber with temperature difference, and because the warm air flow of the heating component in the inner drying chamber blows to the wet articles to be dried and the higher air humidity in the inner drying chamber, moisture will be condensed on the cooler metal circumferential wall and the metal top wall, the condensed water drops along the inner wall of the metal circumferential wall and the metal top wall into the water-expelling slot and is in turn discharged, thereby achieving the purpose of drying the articles intended to be dried.
