CURRENT DETECTING DEVICE, AIR CONDITIONING APPARATUS, CORRECTION CONSTANT CALCULATING SYSTEM AND CORRECTION CONSTANT CALCULATING METHOD
摘要
<p>Provided are a current detecting device by which a highly accurate motor current can be obtained, and an air conditioning apparatus having such current detecting device. Furthermore, a correction constant calculating system and a correction constant calculating method using the current detecting device are also provided.A current detecting device (9) is provided with a current leveling section (93), a GND wiring (94) and a current detecting section (95). The current leveling section (93) levels a drive current (Id) to be carried to a second motor driver (82) for driving a second fan motor (81). A motor current (Im) carried into the second fan motor (81) and the drive current (Id) leveled by the current leveling section (93) are permitted to flow in the GND wiring (94). The current detecting section (95) detects the sum of the motor current (Im) and the leveled drive current (Id) flowing in the GND wiring (94).</p>
