PROBLEM TO BE SOLVED: To provide an efficient and inexpensive refrigerating cycle device suppressing increase in pressure loss in piping between a compressor and an internal heat exchanger and preventing heat movement from the compressor to the internal heat exchanger. SOLUTION: The refrigerating cycle device includes: a refrigerant circuit formed by interconnecting the compressor 11, a radiator 12, a decompression means 13, and an evaporator 14 by refrigerant piping to circulate a refrigerant; and the internal heat exchanger 30 for performing heat exchange between a high-pressure side refrigerant flowing between the radiator 12 and the decompression means 13 and a low-pressure side refrigerant flowing between the evaporator 14 and the compressor 11. The internal heat exchanger 30 is installed near the compressor 11, and a heat insulating material 51 is provided around the internal heat exchanger 30. The refrigerating cycle device can suppress pressure loss in suction piping where pressure loss is likely to increase, and prevent movement of heat from the compressor 11 to the internal heat exchanger 30 of which temperature becomes relatively low, so as to prevent decline in efficiency of a refrigerating cycle.
