VERY LOW TEMPERATURE REFRIGERATOR |
摘要 |
<p>An inverter (22) is provided between a power source (20) and a suction/discharge valve driving motor (14) that controls cycle time of suction and discharge of a refrigerator unit (10). An output frequency of the inverter (22) is controlled in accordance with output of a sensor (24) that detects temperature of a thermal load portion (11) of the refrigerator unit (10). This enables temperature adjustment of individual refrigerators with a highly reliable method without using an electric heater.</p> |
