Abstract
A refrigeration system includes a mass of refrigerant, a reservoir containing a first portion of the mass of refrigerant, and a condenser containing a second portion of the mass of refrigerant. A first sensor is positioned to measure a first parameter of the reservoir and output a first signal indicative of the first parameter. A second sensor is positioned to measure a second parameter of the condenser and output a second signal indicative of the second parameter. A processor receives the first signal and the second signal to calculate a weight of missing refrigerant.
