§431.344. Test procedure for measuring and determining energy efficiency of compressors.
10 C.F.R. § 431.344
Scope. This section is a test procedure that is applicable to a compressor that meets the following criteria:
Is an air compressor;
Is a rotary compressor;
Is not a liquid ring compressor;
Is driven by a brushless electric motor;
Is a lubricated compressor;
Has a full-load operating pressure greater than or equal to 75 pounds per square inch gauge (psig) and less than or equal to 200 psig;
Is not designed and tested to the requirements of the American Petroleum Institute Standard 619, “Rotary-Type Positive-Displacement Compressors for Petroleum, Petrochemical, and Natural Gas Industries;”
Has full-load actual volume flow rate greater than or equal to 35 cubic feet per minute (cfm), or is distributed in commerce with a compressor motor nominal horsepower greater than or equal to 10 horsepower (hp); and
Has a full-load actual volume flow rate less than or equal to 1,250 cfm, or is distributed in commerce with a compressor motor nominal horsepower less than or equal to 200 hp.
Testing and calculations. Determine the applicable full-load package isentropic efficiency (ηisen,FL), part-load package isentropic efficiency (ηisen,PL), package specific power, maximum full-flow operating pressure, full-load operating pressure, full-load actual volume flow rate, and pressure ratio at full-load operating pressure using the test procedure set forth in appendix A of this subpart.
