Relationship Between Refrigeration Oil And Compressor
1. Screw compressor is oil and gas together with oil separator. The oil separation effect is generally 70%-90%, but too much oil in the evaporator will affect the evaporation effect, resulting in high evaporation temperature and poor cooling effect.
2. The centrifugal compressor oil and gas are separated separately. The oil is only supplied to the bearing for lubrication. It is directly returned to the oil tank. Only a small amount of oil will go to the evaporator and return to the compressor through the oil return. The oil in the evaporator can be ignored.
3. The piston compressor is oil and gas separation, the oil is only in the crankcase, only a very small amount of oil goes to the condenser, the evaporator. It is also negligible.
