System of controlling refrigerator temperature |
摘要 |
The present invention continuously speed-controls an electric motor for driving a compressor for refrigerant compression such that the compressor is driven in its maximum rpm if the difference (temperature deviation) between a target cooling temperature and an actual temperature is greater than a first predetermined value, the compressor is stopped if the temperature deviation is less than a second predetermined value, and the compressor is speed-controlled by a digital control signal if the temperature deviation is between said first and second predetermined values.
