PURPOSE: A heat pump type drying machine is provided to improve the quality of dried articles by individually controlling the temperature and humidity of each drying process. CONSTITUTION: A heat pump type drying machine is composed of a refrigeration cycle system and an air control system. The refrigeration cycle system comprises a compressor(1), outdoor and indoor condensers(20,21), a super cooler(31), an expansion valve(4), an evaporator(30), and a hot gas control valve(73). The outdoor and indoor condensers condense refrigerants compressed in the compressor. The super cooler cools the condensed refrigerants. The evaporator evaporates the refrigerants. The hot gas control valve controls the dehumidification function of the evaporator. The air control system comprises an air inlet, an air outlet, a suction chamber, a middle chamber, a circulation chamber, a fan chamber, an external air inflow chamber, an exhaust chamber, an air damper, and an exhaust fan. The suction chamber inhales humid air. The fan chamber supplies high-temperature air to objects. The exhaust chamber exhausts external air passing through the condenser.
