Parallelly connected cold storage cooling system

The invention discloses a parallelly connected cold storage cooling system. The system comprises a first compressor and a second compressor. The first compressor is sequentially communicated with a first oil separator, a first condenser, a stop valve, a liquid storage tank, a liquid supply valve, a first filterer, a first solenoid valve, a first expansion valve, a first evaporator and a first air-liquid separator to go back to an inlet of the first compressor. The system has the advantage that because two cold storage lines apply a same oil storage tank, a same oil supply valve and a same oil filterer, the system can effectively control the oil supply of both the first compressor and the second compressor with high efficiency, thus effectively preventing the compressor damages caused by the lacking of compressor oil of branch lines, therefore greatly enhancing the reliability and stability of the cold storage cooling system. 本发明公开了种并联式冷库制冷系统，所述的并联式冷库制冷系统包含第压缩机和第二压缩机，所述的第压缩机经第油分、第冷凝器、中止阀、储液缸、供液阀、第过滤器、第电磁阀、第膨胀阀
