PROBLEM TO BE SOLVED: To reduce the discharge pulsation of a compressor and to achieve the effect similar as that of an expansion type muffler simple body with a volume of 1/5 ratio of the muffler simple body. SOLUTION: In this transient critical refrigerant cycle device formed by successively circularly connecting the compressor 10, a gas cooler 154, a decompressor 156 and an evaporator 157 by pipes, and using a refrigerant of which a high pressure side has supercritical pressure, an expansion type muffler 191 and a resonator type muffler 193 are mounted on a discharge pipe connecting the compressor 10 and the gas cooler 154, the resonator type muffler 193 has an extension pipe 192 connected with an opening part formed on a lower part of a main body, the pipe 192 is mounted linearly to the gas flow, and the expansion muffler 191 is located at a position after curving the gas flow.
