REFRIGERATION DEVICE AND COOLING AND HEATING DEVICE

摘要

When an in-door heat exchanger acts as an evaporator, each of parts is composed of an inlet part, an intermediate part and an outlet part when observed along the flow of a cooling medium, wherein the in-tube mass flow rates per unit performance of the cooling medium that flows through the above-mentioned parts are not less than 0.44 g/mm2hW and less than 0.50 g/mm2hW, not less than 0.14 g/mm2hW and less than 0.16 g/mm2hW, and not less than 0.13 g/mm2hW and less than 0.15 g/mm2hW, respectively.
