<P>PROBLEM TO BE SOLVED: To provide a vapor drying system capable of efficiently forming a vapor line at low power consumption by using a heating source and a cooling source by a refrigerant generated by a heat pump. Ž<P>SOLUTION: A heat pump circuit 20 includes a compressor 21, a heating coil 22, an expansion valve 23 and cooling coils 24, 25, a drying/liquid-storage tank 10 includes an exhaust duct 30, the cooling coils 24, 25 are disposed in the drying/liquid-storage tank 10 and the exhaust duct 30, and the refrigerant as the cooling source generated in the expansion valve 23 passes through the cooling coil 25 in the exhaust duct 30, and then passes through the cooling coil 24 in the drying/liquid storage tank 10.
