REFRIGERATION CYCLING DEVICE AND EXPANDER INSTALLED IN SAME

摘要

Provided are a refrigeration cycle apparatus (100) and an expander (1) installed in the refrigeration cycle apparatus (100), the apparatus being capable of achieving flow rate matching without pre-expansion or bypassing of an expansion mechanism (2). The refrigeration cycle apparatus (100) includes an expander (1) including an orbiting scroll (52) which includes a baseplate and spirals arranged on both surfaces of the baseplate, respectively, the baseplate having a high-pressure introduction hole (52e) guiding the pressure of a refrigerant sucked in an expansion mechanism (2) to a sub-compression mechanism (3).
