SYSTEM LOW TEMPERATURE REFRIGERATOR HAVING UNIFORM REFRIGERANT FLOW

摘要

PURPOSE: A system low temperature refrigerator having a smooth refrigerant flow is provided to transfer a refrigerant discharged from an evaporator to a compressor, thereby increasing the viscosity of the refrigerant. CONSTITUTION: A recovering pipe structure of a system low temperature refrigerator(100) includes a compressor(10) and evaporators of a plurality of storage units. A recovering pipe(60) includes a main recovering pipe and an auxiliary recovering pipe. The main recovering pipe is connected to the compressor. The auxiliary pipe is branched from the main recovering pipe, is respectively connected to the evaporators, and has a diameter smaller than that of the main recovering pipe.
