A drying system using a heat pump is provided to forecast a dried state of the drying object in a case of a load cell to be installed and maximize a drying efficiency by adjusting a plurality of dampers. In a drying system using a heat pump(10), a frame(12) includes a drying space(15) inside for drying the drying object. A compressor(20) is installed on the frame and includes a refrigerant. A condenser(22) is installed in the drying space and a heat of the refrigerant compressed in the compressor is radiated. An expanding unit(24) is installed on the frame and the refrigerant condensed in the condenser. An evaporator is installed in the drying space and the refrigerant expanded in the expanding unit absorbs the heat and is condensed. A first external air incoming hole(40) is placed on an upper flow portion of the evaporator among an air circulation path of the frame inside for allowing the external air to pass the evaporator. A first damper(61) operates to control a ratio of the air, entering through the first external air incoming hole, among the air passing the evaporator. A first outlet hole(51) is placed on a lower flow portion of the evaporator among the air circulation path of the frame inside for allowing the air passing the evaporator to be discharged from the frame outside. A second damper(62) operates to control a ratio of the air, discharged through the first outlet hole, among the air passing the evaporator. A second external air incoming hole(42) is placed on an upper flow portion of the condenser among the air circulation path of the frame inside for allowing the external air to pass the condenser. A third damper(63) operates to control a ratio of the air, entering through the second external air incoming hole, among the air passing the condenser. A second outlet hole(52) is placed on a lower flow portion of the condenser among the air circulation path of the frame inside for allowing the air passing the condenser to be discharged from the frame outside. A fourth damper(64) operates to control a ratio of the air discharged through the second outlet hole among the air passing the condenser.
