PURPOSE: An oil recovery system of a turbo freezer is provided to improve the efficiency of a turbo freezer by blocking the inflow of oil into a compressor or evaporator. CONSTITUTION: An oil recovery system of a turbo freezer comprises an oil tank, an oil pump, a motor, and first and second oil recovery lines. The oil tank is formed in a compressor and stores oil. The oil pump provides power for circulating oil. The motor drives the compressor. The first oil recovery line connects a volume housing(11) to the rear end of the compressor(19). The second oil recovery line connects an evaporator to the rear end of the compressor. The first and second oil recovery lines separate refrigerant and oil from a mixture of oil discharged into the motor and refrigerant cooled through the motor and collects the separated oil.
