Abstract
A condensing type clothes dryer having a heat pump cycle is provided that may include a drum in which an object to be dried may be accommodated; a circulation duct that forms a circulation passage such that air may circulate via the drum; and a heat pump cycle. The heat pump cycle may include a plurality of evaporators provided adjacent to each other in the circulation duct; a condenser provided at a downstream side of the plurality of evaporators and spaced therefrom, that absorbs heat of air discharged from the drum through the plurality of evaporators, and transfers the heat to air introduced into the drum through the condenser, using an operation fluid, which may circulate via the plurality of evaporators and the condenser; a plurality of divergence pipes that form a divergence passage, such that the operation fluid discharged from the condenser may be introduced into each of the plurality of evaporators; a plurality of electronic expansion valves provided at the plurality of divergence pipes, respectively, that opens and closes the plurality of divergence passage; and a controller that controls a flow amount of the operation fluid to be introduced into each of the plurality of…
