Title:
CALIBRATION METHOD FOR ESTIMATED ENERGY CONSUMPTION AMOUNT CALCULATION CHARACTERISTIC FORMULA AND AIR CONDITIONING HEAT SOURCE SYSTEM
Document Type and Number:
Japanese Patent JP2016065661
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To cause an estimated energy consumption amount to be approached to an actual energy consumption amount as much as possible even if an actual measured value of energy consumption amount is remarkably far away from a device characteristic.SOLUTION: This invention comprises a step [S2] of calculating a minimum estimated energy consumption amount required for satisfying an air conditioning load in respect to a plurality of air conditioning loads by using a pre-determined characteristic formula of air conditioning facility; a step [S4] of operating air conditioning facility so as to satisfy the air conditioning load; a step [S5] of measuring an actual energy consumption amount of air conditioning facility; a step [S7] of calculating a correction coefficient of characteristic formula of air conditioning facility for calculating an estimated energy consumption amount in reference to an estimated energy consumption amount and an actual energy consumption amount corresponding to a plurality of air conditioning loads, each of the steps is executed repeatedly for a pre-set time and after that, executing the step [S7] of calculating the coefficient of correction and setting a characteristic formula calculating the estimated energy consumption amount F on the basis of the calculated coefficient of correction.SELECTED DRAWING: Figure 2
