<P>PROBLEM TO BE SOLVED: To enhance energy saving in a refrigerating device for a trailer by changing rotation speed of a motor of a compressor to follow the variation of a cooling load in a container without using an inverter. <P>SOLUTION: The refrigerating device (10) for the trailer includes a throttle adjusting mechanism (6) for adjusting rotation speed of the compressor motor (7) by varying rotation speed of an engine (2) for power generation to change the frequency and voltage of AC power, and a control controller (40) for adjusting a cooling capacity in the container (51) by controlling the throttle adjusting mechanism (6) based on the cooling load in the container (51). <P>COPYRIGHT: (C)2013,JPO&INPIT |
