PROBLEM TO BE SOLVED: To provide a heat storage tank, capable of storing cold heat by ice, even when non-azeotropic mixture refrigerant is employed as a refrigerant or improving efficiency upon using the cold heat thereafter, and a refrigerating cycle device and an air conditioning device equipped with the same. SOLUTION: The heat storage tank 42, having a pipe-type heat exchanger 18 arranged in a water tank 14 and producing ice K for storing cold heat, by cooling water W contacting the outer peripheral surface by passing the refrigerant through the inside of the same, employs the non-azeotropic mixture refrigerant as the refrigerant and is provided with a difference of growing degrees of ice-restraining means for restraining a difference between the growing degrees of ice K, produced on the outer peripheral surface of the heat exchanger 18 at one end part and the other end part of the same or a circulating water passage 44 and a pump 46. |
