Abstract: A combination washer and dryer appliance includes a cabinet, a drum housing and a drum with a drum wall that defines a laundry compartment. A drying air circulation path extends from an inlet positioned a drum wall to an outlet positioned in fluid communication with the laundry compartment. A filter coil is disposed adjacent to the drying air inlet. A condensing system includes the filter coil located on the drum wall at the drying air inlet and a second coil located in the cabinet and outside of the drying air circulation path. The filter coil and second coil are arranged in fluid communication and containing a heat-transfer fluid such that the filter coil acts as both a lint filter. A condenser dehumidifies drying air entering the drying air inlet and such that the second coil acts as a heat exchanger for transferring heat to ambient air located inside the cabinet.
