Abstract (en)
[origin: EP2009371A1] It is an object of the present invention to prevent a shortage of suction gas in a compressor by ensuring that surplus refrigerant does not occur in a refrigerant circuit and to suppress the occurrence of noise in the vicinity of a rotary type compressor. A refrigerating apparatus (1) is disposed with a compressor (21), a first heat exchanger (22), an expansion mechanism (23), a second heat exchanger (24) and a muffler (26). The compressor is a rotary type compressor that compresses a refrigerant. The first heat exchanger causes the refrigerant of a high temperature and a high pressure that has been compressed by the compressor to exchange heat with a first fluid. The expansion mechanism reduces the pressure of the refrigerant that has been condensed inside the first heat exchanger. The second heat exchanger causes the refrigerant whose pressure has been reduced by the expansion mechanism to exchange heat with a second fluid. The muffler is disposed between the second heat exchanger and the compressor and reduces the pulsation of the flow of the refrigerant.
