<p><P>PROBLEM TO BE SOLVED: To provide a refrigerating cycle apparatus, restraining the occurrence of decomposition and polymerization due to chemical reaction of a refrigerant having double bond of carbon even when using a mixed refrigerant containing a high boiling point refrigerant and a low boiling point refrigerant having double bond of carbon in a composition. <P>SOLUTION: This refrigerating cycle apparatus using a mixed refrigerant containing a high boiling point refrigerant and a low boiling point refrigerant having double bond of carbon in a composition, includes: a refrigerant separator which separates the mixed refrigerant into a high boiling point component refrigerant and a low boiling point component refrigerant; a first expansion device, which pressure-reducing the high boiling point component refrigerant; a high and low pressure heat exchanger, which performs heat exchange between the high boiling point component refrigerant pressure-reduced by the first expansion device and the condensed mixed refrigerant; a first compression element, which compresses the high boiling point component refrigerant; a second expansion device, which pressure-reduces the low boiling point component refrigerant; an evaporator, which evaporates the low boiling point component refrigerant: a second compression element, which compresses the low boiling point component refrigerant; and a joining part where the compressed high boiling point component refrigerant and the low boiling point component refrigerant join each other. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
