Freezer ammonia refrigeration system with hot ammonia is towards white return circuit

The utility model provides a freezer ammonia refrigeration system with hot ammonia is towards white return circuit, includes high -pressure ammonia storage tank, choke valve, low -pressure circulationbarrel, liquid ammonia pump, evaporimeter, compressor, condenser, jettison gear, hot ammonia towards white return circuit, the utility model discloses the jettison gear that the sets up sedimentary oil in the low -pressure circulation barrel of effectively discharging has effectively been avoided oily entering evaporimeter and has been influenced the refrigeration performance of ammonia refrigeration equipment, hot ammonia can cooperate the jettison gear to detach the oil of a small amount of entering evaporimeter towards white return circuit, has further improved the heat transfer performance of evaporimeter, and hot ammonia can also effectively dash the frost to the evaporator coil outer wall towards white return circuit, and then improves the heat transfer efficiency of evaporimeter, the improve equipment perf
