PROBLEM TO BE SOLVED: To provide a refrigeration unit capable of stabilizing the behavior of oil and the like in a compressor, and improving the reliability. SOLUTION: This refrigeration unit is provided with the compressor 2 and an evaporator 7 connected to a suction pipe of the compressor. A heat exchanging part of the evaporator is divided into a main heat exchanging part 7A and a sub-heat exchanging part 7B mounted at the downstream of the main heat exchanging part 7A, a gas-liquid separating means 9 for separating the refrigerant having passed through the main heat exchanging part, into the gas and liquid, is mounted between the sub-heat exchanging part and the main heat exchanging part, a liquid refrigerant supplying means 11 is mounted to supply the liquid refrigerant separated by the gas-liquid separating means 9 to the sub-heat exchanging part, and a gas refrigerant supplying means 13 is mounted to making the gas refrigerant separated by the gas liquid separating means, bypass the sub-heat exchanging part to be supplied to the suction pipe of the compressor 2.
