Title: COATING DRYING METHOD AND DEVICE THEREFOR
Abstract:
The present invention involves: extracting in-furnace air from a dry furnace 1 for drying a coating film of a workpiece 2; cooling the air so as to condense and remove portions of at least water and a VOC in the air; and heating the cooled air and returning the air to the dry furnace 1. A heat pump 3 that uses the air removed from the dry furnace 1 as a heat absorption source and uses the cooled air as a heat radiation source is provided. The air is cooled and heated by using the heat pump 3.
