A dehumidifier for a compressor, including: a plurality of dehumidifying members that absorb moisture; and a flow passage controlling valve module that enables a low-temperature vapor refrigerant to alternately flow into the plurality of dehumidifying members and enables the low-temperature refrigerant to flow into a compressor in a state where moisture contained in the low-temperature refrigerant is absorbed and is removed, enables a high-temperature vapor refrigerant ejected from the compressor to alternately flow into the dehumidifying members and regenerates the dehumidifying members. Thus, since a liquid-state absorbent contained in a refrigerant flowing into the compressor is removed by the dehumidifier, damage caused by liquid compression and corrosion of the compressor can be reduced. In addition, the structure of the dehumidifier is simple, and an additional external heating source is not required.
