<p>A method of controlling the temperature in a refrigerator composed of a compressor, a condenser, a refrigerant flow-rate regulating valve, an evaporator, etc. A first control signal generated on the basis of the temperature in the part of the refrigerator being cooled is compared with a second control signal generated on the basis of an overheating temperature calculated from the temperature and pressure on the evaporator outlet side, and whichever of the signals is smaller is selectively output as a control signal for adjusting the opening of the flow-rate regulating valve, making it possible to stably control the temperature in the part being cooled, and prevent the return of refrigerant liquid to the compressor. </p> |
