PURPOSE: A dryer is provided to be able to maintain the inner temperature of a dry box to the optimal temperature through a refrigerant circulation group having a composite heat regenerator. CONSTITUTION: A dryer comprises the following: a drying room(110) in which a drying object is placed and dried; a compressor(120) compressing gas refrigerant at a high temperature and low pressure; a first condenser(130) heating internal air while condensing through the first heat exchange of the gas refrigerant at a high temperature and low pressure transferred from the compressor and the internal air; a composite heat regenerator(140) performing the second heat exchange using liquid refrigerant at a high temperature and high pressure transferred from the first condenser; a second condenser(150) re-condensing the liquid refrigerant at a high temperature and high pressure; a liquid receiver(160) transferring the liquid refrigerant at a high temperature and high pressure through an inner capillary; expansion heat(170) expanding the liquid refrigerant at a high temperature and high pressure; and an evaporator(180) condensing inner moisture while evaporating through the third heat exchange of the liquid refrigerant at a low temperature and low pressure transferred from the expansion heat, and inner moisture in the drying room. |
