<P>PROBLEM TO BE SOLVED: To accurately determine and present loss in power consumption of an air conditioning apparatus. <P>SOLUTION: A power diagnostic system 1 includes a parameter acquisition part 231, a determination part 232, an estimation part 233, a power consumption acquisition part 234, a calculation part 235, and a display device 3. The parameter acquisition part 231 acquires a value of a parameter indicating an environmental state of a predetermined space. The determination part 232 determines whether the environment of the predetermined space is a comfortable state or not in accordance with level relation between the parameter value and a threshold. When a period that an environment of the predetermined space is a comfortable state is continued for a fixed period the estimation part 233, estimates the power consumption of the air conditioning apparatus 5 in a condition that the setting of the air conditioning apparatus 5 is changed to a direction for reducing the power consumption. The calculation part 235 finds out loss in the power consumption of the air conditioning apparatus 5 by using actual power consumption and the estimated power consumption. The display device 3 presents an occurrence timing of loss in the power consumption and the loss of the power consumption found out by the calculation part 235. <P>COPYRIGHT: (C)2012,JPO&INPIT |
