Abstract

A refrigerant compressor (10) uses carbon dioxide as a refrigerant. A casing (13) houses a crankshaft (25), a motor (21), and a compression mechanism (30). The crankshaft (25) is provided with, at a lower end portion thereof, an oil supply mechanism (38) having a suction port (39) through which oil stored in a lower end portion of the casing (13) is drawn. A displacement volume Vcc [cc] per rotation of the compression mechanism (30) and a distance L1 [mm] between the suction port (39) and a lower end of a member joined to the casing (13), among members constituting the compression mechanism (30), satisfy the following condition: L 1 / Vcc > 13 . <img class="EMIRef" id="5739c957-1320-495d-92b5-3d7afefa9609-ia01" />
