ABSTRACT:
Dry cleaning of goods using perchloroethylene as solvent, in which during drying and deodorizing operations a flow of air is created by a fan in a closed circuit, vapour of the solvent is condensed solely by a refrigerated condenser, and during deodorizing the flow of air created by the fan is directed through a passage which restricts the flow, whereas during drying, the air is permitted to flow more freely, whereby during deodorizing the flow of air over the condenser is a minor fraction only of the flow of air through the goods during drying.
