  • Patent number: 4622039
    Abstract: According to the present invention, a dry cleaning washer and a dryer are arranged in a closed cycle system so that the effluent solvent vapor from the washer is delivered to an accumulator chamber generally simultaneously with the delivery from the dryer of effluent hot air. The hot air super heats the solvent vapor increasing its volitization and the heated and highly volatile solvent vapors are then passed to a condenser which includes the feed coils for supplying clean air to the dryer. In passing through the condenser, the super heated solvent vapor, instantly liquifies giving off its heat to the cool air, thus preheating the clean air prior to its entry into the dryer. The liquified solvent is returned to the washer, or to a storage reservoir.
