METHOD FOR CONTROLLING THE OPERATION OF SMALL-AND-MEDIUM LOW TEMPERATURE STORAGE, CAPABLE OF CONTROLLING EFFICIENCY THE OPERATION OF THE SMALL-AND-MEDIUM LOW TEMPERATURE STORAGE

摘要

PURPOSE: A method for controlling the operation of small-and-medium low temperature storage is provided to reducing time required for cooling, to solve problems of the non-uniformity and instability of the temperature of a compartment, and to reduce energy consumption.;CONSTITUTION: A method for controlling the operation of small-and-medium low temperature storage comprises: a setting input step(100) for inputting set values required for controlling the small-and-medium low temperature storage; a cooling operation step(200) for cooling according to the set values; a real time based recognition step(300) for recognizing a current value of an air blower measured in the prior step; a cooling operation maintaining step(400) for maintaining the cooling operation when a difference of the measured current value and an initial current value of the air blower is larger than the set value; a discharging step(500) for discharging waste defrosting heat to the outside of the low temperature storage; an air blower current detecting step(600) for detecting a current value of the air blower by operating the air blower for a preset period after a preset delay period; and a defrosting completion step(700) for completing defrosting when the detected current value is larger than the initial current value of the air blower.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Cyclic defrosting method; (BB,KK) Freezing operation; (CC) Time period = Freezing time; (DD) Time period = 6 hours; (EE,NN) Defrosting operation; (F1,O1) Stop a compressor; (F2,O2) Stop a blower; (F3,O3) Operate a defrosting heater for a set time; (GG,SS) Finish defrosting; (HH,TT) Delay freezing; (II) Delay time = 5 minutes; (JJ) The present invention; (LL) Freezing operation; (LL) Current difference Set value; (MM) Set value = 0.65-0.75 maximum current difference; (O4) Operate a waste heat discharge device for a set time; (O5) Activate detection of blower current for a set time after a set delay time passed; (O6) Detect a current difference; (PP) Detected current value = Initial current value; (QQ) Re-defrosting operation; (RR) Operate the defrosting heater and the waste heat discharge device for a set time; (UU) Delay time = 0.5-1 minute
