Document Type and Number:
Japanese Patent JP6150906
Kind Code:
B2
Abstract:
A refrigeration cycle apparatus (100) includes a refrigerant circuit including a compressor (1), a condenser, an expander (3), and an evaporator connected by pipes so that refrigerant is circulated therethrough. The expander (3) includes: an expander shell (34) defining an outer shell; an expansion unit (31) arranged in the expander shell (34) and configured to expand the refrigerant flowing out from the condenser to generate driving force, and configured for causing the expanded refrigerant to flow into the evaporator; and a power generator (32) arranged in the expander shell (34) and configured to rotate by the driving force generated by the expansion unit (31). The expander shell (34) is configured such that refrigerating machine oil (50) contained in the refrigerant discharged from the compressor (1) is stored therein, and is supplied to at least one of the expansion unit (31) and the power generator (32).
