PROTECTION AND DIAGNOSTIC MODULE FOR A REFRIGERATION SYSTEM |
摘要 |
<p>A system includes a compressor and a compressor motor functioning in a refrigeration circuit. A sensor produces a signal indicative of one of current and power drawn by the motor and a liquid-line temperature sensor provides a signal indicative of a temperature of liquid circulating within the refrigeration circuit. Processing circuitry processes the current or power signal to determine a condenser temperature of the refrigeration circuit and a subcooling value of the refrigeration circuit from the condenser temperature and the liquid-line temperature signal.</p> |
