Abstract
In a refrigerant circulating apparatus, a liquid accumulating container for allowing oil droplets to flow out in suspended form is connected between a condenser and a pressure reducing device. Thus, refrigerating machine oil which flowed out from a compressor can be reliably returned to the compressor, and proper lubricating and sealing functions can be maintained for the compressing elements.
