Abstract
A dryer is provided. The dryer may include a second condenser integrally provided with an evaporator and employing a heat pump to maximize a condensation effect so as to enhance heat exchange efficiency, thereby enhancing dehumidifying capability. The dryer may be a circulation type heat pump dryer including a cabinet, a drum, a drying duct to circulate dry air back to the drum, an evaporator having a heat pump, a first condenser, a compressor, an expansion apparatus, and a second condenser to condense refrigerant condensed by the first condenser again so as to supercool the refrigerant during the refrigerant cycle, thereby enhancing dehumidifying capability in the evaporator.
