REFRIGERATOR OPERATION SYSTEM BASED ON HEAT SOURCE COST AND ITS METHOD, ESPECIALLY COMPRISING LOAD RATIO CALCULATION UNIT AND REFRIGERATOR SELECTION UNIT

摘要

PURPOSE: A refrigerator operation system based on heat source cost and its method are provided to reduce energy consumption by operating a building refrigerator efficiently on the ground of systematic data. CONSTITUTION: A data input unit(10) receives data from the external and stores them according to the kind of input information. A cost calculation unit(20) calculates cost spent by each refrigerator per heat capacity. A load ratio calculation unit(30) calculates load ratio per time according to external temperature information inputted through the data input unit. A load calculation unit(40) calculate cooling load consumed during a corresponding time using the load ratio calculated by the load ratio calculation unit. A refrigerator selection unit(50) determines a minimum number of refrigerators. And a display unit displays the calculation or determination result by each calculation unit and the selection unit.
