Refrigerating device

摘要

A refrigerating device having an inverter circuit for generating alternating voltage, a vibrating compressor to which the alternating voltage from the inverter circuit is supplied, a condenser to which the refrigerant compressed by the compressor is supplied, a capillary tube provided on the downstream side of the condenser and an evaporator provided on the downstream side of the capillary tube, wherein a phase control circuit for controlling the phase of the alternating voltage supplied to the compressor in accordance with ambient temperature of the refrigerating device and/or the evaporator temperature is provided to cause the piston stroke of the vibrating compressor to be reduced in accordance with decreases in ambient temperature of the refrigerating device and/or the evaporator temperature so as to prevent unwanted damage to the compressor.
