摘要 |
The invention concerns a method and a cooling system for oil separation in a cooling circuit, including compression means (4) that supply coolant under a first high pressure through means for oil separation (10) and further on through condensing means (12), from where coolant is applied restriction means (16), from where coolant is conducted to flooded evaporation means (18), from where the compression means (4) suck gaseous coolant back, where remaining oil in the flooded evaporation means is returned to the cooling circuit through an oil removal circuit (26). It is the purpose of the invention to achieve an efficient oil separation from a flooded evaporator (18). This may be attained by the cooling system according to the invention, in that the oil removal circuit (26) includes a pump (24), the suction side of which being connected to the flooded evaporator (18), where the pressure outlet of the pump is connected to a pressure connection (9) between the pressure outlet of the compressor (4) and the oil separator (10). |
