Claim:
1. An accumulator comprising: a tank separating refrigerant flowing to the tank into vapor-phase refrigerant and liquid-phase refrigerant, the tank therein storing the liquid-phase refrigerant and emitting the vapor-phase refrigerant toward a suction side of a compressor; and a desiccant disposed in the tank and removing a water content from the refrigerant, wherein liquid-phase refrigerant included in the refrigerant flowing to the tank drops downward from a location that is located above the desiccant, and is stored in a lower portion in the tank, vapor-phase refrigerant included in the refrigerant flowing to the tank is drawn through a suction port that is located above the desiccant to flow out of the tank, at least a part of the desiccant is exposed to vapor-phase refrigerant under a normal condition, and the desiccant is located at a location that is away from a dropping route of liquid-phase refrigerant in the tank, and the desiccant has an exposed portion that is always located above a highest liquid level of the liquid-phase refrigerant stored in the tank while an operation of the compressor is stopped.
