| 摘要 |
A cold storage tank unit for a refrigeration cycle apparatus includes a cold storage heat exchanger having plural tubes and a pair of first and second tanks connected to longitudinal ends of the tubes, a cold storage material tank which accommodates at least the tubes of the cold storage heat exchanger, and a cold storage material filled in the cold storage material tank. The cold storage material is cold-stored by the refrigerant or is cold-released to cool gas refrigerant evaporated in the evaporator. Furthermore, the second tank has a lower end portion that is positioned lower than a lower end portion of the first tank, and the second tank has a tank capacity capable of storing a predetermined liquid refrigerant condensed by cold storage heat of the cold storage material. The cold storage tank unit can be located between an evaporator and a compressor in the refrigeration cycle apparatus.
