Abstract
A condensing type clothes dryer having a heat pump cycle and a method for controlling a condensing type clothes dryer having a heat pump cycle are provided. The condensing type clothes dryer 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; a circulation fan configured to circulate the air along the circulation duct; a heat pump cycle having an evaporator and a condenser spaced from each other in the circulation duct, and configured to absorb heat of air discharged from the drum through the evaporator and to transfer the heat to air introduced into the drum through the condenser using an operation fluid which may circulate via the evaporator and the condenser; a bypass flow path formed at the circulation duct such that a portion of air discharged from the drum may bypass the evaporator to be mixed with air having passed through the evaporator at an upstream side of the condenser; and an opening and closing device installed at the bypass flow path and configured to selectively open or close the bypass flow path.
