<p><P>PROBLEM TO BE SOLVED: To provide a compressor reducing loss work and exhibiting high performance when a refrigerant in use is changed to R1234yf being a new refrigerant, and to provide a refrigerating cycle achieved in the high coefficient of performance (COP) by using the compressor. <P>SOLUTION: This compressor compresses the refrigerant, HFO1234yf is used as the refrigerant, and the channel cross-sectional area of a main pressure loss generating part is enlarged 1.05-1.40 times in comparison with the case that HFC134a is used as the refrigerant. The refrigerating cycle uses the compressor. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
