SYSTEM LOW TEMPERATURE REFRIGERATOR AND METHOD FOR DRIVING CONTROL THEREOF

摘要

PURPOSE: A system low temperature refrigerator is provided to efficiently manage various low temperature storages, thereby minimize the power consumption. CONSTITUTION: A system low temperature refrigerator comprises a compression and condensation module(20), a plurality of valves(30), a plurality of storage(10), and a central controller(40). The compression and condensation module includes a compressor converting a gaseous refrigerant into a high-temperature and high-pressure gas by compressing and a condenser condensing the compressed refrigerant. A plurality of valves expands the refrigerant discharged from the condenser, thereby discharging the refrigerant of low-temperature and low-pressure. A plurality of storage is connected respectively to a plurality of valves, is installed separately from the compression and condensation module, and includes an evaporator decreasing the inner temperature while the refrigerant of the low-temperature and low-pressure is vaporized. The central controller controls a plurality of valves according to the operation of the compressor.
