PURPOSE:To display electric power consumption of each product, by obtaining a transition table corresponding a detected amount of operation of each product to a power consumption per unit time and obtaining the power consumption through the use of this table. CONSTITUTION:For example, as a component using a steady power consumption for a cooler, a control circuit is said component, and the components for non- steady power consumption are compressor, indoor fan and outdoor fan. The power consumption of each component in the unit time is taken as P0-P3. The P0 is a constant, which is experimentally determined. As to the P1-P3, the numbers of revolution are taken as the detection amount as V1-V3 and the relation of correspondence are determined with the P1-P3 from experiments and the data are set to a computer system as tables T1-T3. A computer 40 samples V1-V3 at each unit time, P1-P3 are calculated referring to T1-T3 and the integrated power consumption P is obtained and displayed on a display 70. Thus, the power consumption of each product can be displayed. |
