Title:
REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/207491
Kind Code:
A1
Abstract:
Electric power generated by a generator (32) driven by an engine (31) is converted by an inverter (33) into an alternating current having an arbitrary frequency. A compressor (11) constituting a refrigeration cycle (10) has: a motor (16) driven by electric power supplied from the inverter (33); and a refrigerant compression section (17) rotationally driven by the motor (16) to suck in a refrigerant and compress and discharge the refrigerant. A mode selector switch (44) is capable of selecting between a start/stop operation mode in which the start and stop of the engine (31) is permitted, and a continuous operation mode in which the engine (31) is operated continuously. When the start/stop operation mode is selected by the mode selector switch (44), a control device (40) controls the inverter (33) so that a target rotational speed of the compressor (11) is affixed at a rotational speed higher than a rotational speed corresponding to the difference between a set temperature (Tset) and an in-compartment temperature (Tret).
