How can the BTU rating of a compressor be determined?

Capacity ratings for Copeland® compressors are found on our published performance curves. These curves can be obtained through our wholesalers or from the Online Product Information section of our website. To use these curves, convert the measured suction and discharge pressure readings to their corresponding evaporating and condensing temperatures using a pressure/temperature chart for the refrigerant being used. Plotting those temperatures on the performance curve tables will reveal the BTU/H ratings, amperage, and watts.
