Document Type and Number:

Japanese Patent JP2001141315

Kind Code:

A

Abstract:

To provide a refrigerating air conditioner capable of supplying lubricating oil sufficiently to not only a compressor but also an expanding machine.

A refrigerating air conditioner 1 is provided with a compressor 21 for compressing refrigerant 5, a radiator 16 for cooling the compressed refrigerant 5, an expanding machine 22 for expanding the refrigerant 5 which passed the radiator 16, an evaporator 17 for evaporating the expanded refrigerant 5 and a refrigerant pipeline 11 for circulating the refrigerant 5 through these instruments. An oil separator 12 for separating lubricating oil 6 contained in the refrigerant 5 passed through the compressor 21 is arranged between the compressor 21 and the radiator 16. The oil separator 12 is provided with an oil returning pipe 13 for returning the lubricating oil 6 and separated from the refrigerant 5 to a part between the evaporator 17 and the compressor 21, and an oil sending pipe 14 for sending lubricating oil 6 to a part between the radiator 16 and the expanding machine 22.
