<p><P>PROBLEM TO BE SOLVED: To provide the technology capable of preventing degradation of energy efficiency and comfort even when a serviceman forgets a switching operation from an emergency operation mode to a normal operation mode, in an air conditioning device having coordination work of an invertor compressor and a constant-velocity compressor. <P>SOLUTION: When an instruction to switch a mode to the emergency operation mode is input (YES in #1), a mode setting section switches the operation mode of the air conditioning device 1 to the emergency operation mode, and a timer starts its time measuring operation (#2). Then a determining section determines whether the measured time of the timer reaches an emergency operation time memorized in an emergency operation time memorizing section or not (#3), so that when the measured time does not reach the emergency operation time (NO in #3), the mode setting section keeps the emergency operation mode, while, when the measured time reaches the emergency operation time (YES in #3), the mode setting section switches the mode from the emergency operation mode to the normal operation mode (#4). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
