PROBLEM TO BE SOLVED: To easily maintain the stable state by calculating transition time to map transfer time of fuel quantity and/or ignition timing when detecting that a refrigerant circuit is put in a stable state, and deciding the fuel quantity and/or the ignition timing by the map transfer time on the basis of the transition time. SOLUTION: In a thermal transfer device for driving compressors 2A, 2B in an outdoor unit by an engine 40 in a heat pump and a refrigerator, a control part 71 infers a correction factor Tn from a differential value of a deviation of an engine speed to judge whether or not to perform stable control on the basis of the size of this correction factor Tn. That is, when an absolute value of the correction factor Tn is smaller than a stable level value X, the stable control is started. At this stable control time, a difference K between the correction factor Tn and the stable level value X is calculated to multiply this difference K by a stable time factor and stabilizing time as well as to add allowable minimum transition time to calculate transition time so as to decide fuel quantity and ignition timing by map transfer time on the basis of the transition time.
