PROBLEM TO BE SOLVED: To solve a problem of wasting power consumption that occurs to conventional case heaters and constraint power supply since power is always supplied while a compressor stops operating irrespectively of whether refrigerant stagnates and the power supply continues without refrigerant stagnation.SOLUTION: A drive control device 5 for a refrigeration cycle compressor includes: refrigerant expelling means for expelling refrigerant remaining in a compressor of a refrigeration cycle device; a clock timer (present-time measuring means) 502 for measuring present time; and a drive control unit (control means) 501 for actuating constraint power supply (refrigerant expelling means) when the present time measured by the clock timer 502 reaches preheating-start planned time set and input in advance. It is thereby possible to expel the stagnant refrigerant and reduce the waste of power consumption. |
