本发明通过采用立式储液罐2、制冷压缩机3、油分离器6、储油罐7的结合设计，使得润滑油经油分离器6与气体制冷剂分离后，流向储油罐7，从而可大大减少制冷剂内润滑油的充注量。The invention adopts a combination design of a vertical liquid storage tank 2, a refrigeration compressor 3, an oil separator 6, and an oil storage tank 7, so that the lubricating oil is separated from the gas refrigerant by the oil separator 6, and then flows to the oil storage tank 7, Thereby, the amount of lubricating oil in the refrigerant can be greatly reduced.

在使用时，在冰场制冰排管里经吸热蒸发变成制冷剂气体并与未能蒸发剩余的液体形成混合状态的制冷剂进入立式储液罐2内，而混合状态制冷剂中的制冷剂气体从立式储液罐2的出气接口经吸气阀8被吸向制冷压缩机3，此时，制冷剂气体经制冷压缩机3压缩后变成为高压高温气体，然后连同制冷压缩机3的润滑油，经制冷压缩机3出口端流向油分离器6，而经油分离器6拦截后的润滑油从油分离器6的出液端流向储油罐7备用；而经过油分离器6后较为净化的高压制冷剂气体经油分离器6的出气端流向冷凝器，而该高压高温制冷剂气体经冷 凝器冷凝后变为高压常温制冷剂液体，并经冷凝器流向节流阀12，而高压常温制冷剂液体经节流阀12变成低压低温的制冷剂液体，然后经节流阀12流向立式储液罐2备用。In use, in the ice rink ice-making tube, the refrigerant is vaporized by the endothermic evaporation into a refrigerant gas and is mixed with the liquid that fails to evaporate the remaining liquid into the vertical liquid storage tank 2, and in the mixed state refrigerant The refrigerant gas is sucked from the air outlet of the vertical liquid storage tank 2 through the suction valve 8 to the refrigeration compressor 3. At this time, the refrigerant gas is compressed by the refrigeration compressor 3 to become a high-pressure high-temperature gas, and then cooled together. The lubricating oil of the compressor 3 flows to the oil separator 6 through the outlet end of the refrigeration compressor 3, and the lubricating oil intercepted by the oil separator 6 flows from the liquid outlet end of the oil separator 6 to the oil storage tank 7 for standby; After the separator 6, the relatively purified high-pressure refrigerant gas flows to the condenser through the gas outlet end of the oil separator 6, and the high-pressure high-temperature refrigerant gas is cooled. After the condenser is condensed, it becomes a high-pressure normal temperature refrigerant liquid, and flows through the condenser to the throttle valve 12, and the high-pressure normal temperature refrigerant liquid becomes a low-pressure low-temperature refrigerant liquid through the throttle valve 12, and then flows through the throttle valve 12 to the vertical The liquid storage tank 2 is ready for use.
