A refrigeration system can incorporate a liquid-injection system that can provide a cooling liquid to an intermediate-pressure location of the compressor. The cooling liquid can absorb the heat of compression during the compression of the refrigerant flowing therethrough. The refrigeration system can include an economizer circuit that injects a refrigerant vapor into an intermediate-pressure location of the compressor in conjunction with the injection of the cooling liquid. The incorporation of the vapor injection in conjunction with the cooling-liquid injection can advantageously increase the cooling capacity and/or efficiency of the refrigeration system and the performance of the compressor.
