<P>PROBLEM TO BE SOLVED: To provide a refrigeration device that, even when using a cooling medium with its cooling capacity per unit volume smaller than that of a refrigerant R410A, can reduce pressure loss in an indoor heat exchanger to secure the cooling capacity, and exhibits high efficiency. <P>SOLUTION: The refrigeration device is configured such that an indoor unit, when functioning as an evaporator, is composed of an inlet part, an intermediate part, and an outlet part as observed along the flow of a cooling medium, wherein the in-tube mass flow rates per unit performance of the cooling medium as flowing through each of the parts are: ≥0.44 g/mm2hW and <0.50 g/mm2hW; ≥0.14 g/mm2hW and <0.16 g/mm2hW; and ≥0.13 g/mm2hW and <0.15 g/mm2hW, respectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
