Air conditioner

An air conditioner in which a mixed refrigerant that includes at least 1,2-difluoroethylene is used, wherein increased efficiency is achieved. The motor rotation speed of a compressor (100) can be changed in accordance with the air conditioning load, and therefore it is possible to achieve high annu...

Beschreibung
Zusammenfassung:	An air conditioner in which a mixed refrigerant that includes at least 1,2-difluoroethylene is used, wherein increased efficiency is achieved. The motor rotation speed of a compressor (100) can be changed in accordance with the air conditioning load, and therefore it is possible to achieve high annual energy consumption efficiency (annual performance factor). Furthermore, no electrolytic capacitor is required on the output side of a rectification circuit (21), and therefore increased size and cost of the circuit can be suppressed.
