Energy Conservation Program: Test Procedures for Compressors

In this document, the U.S. Department of Energy (DOE) proposes to prescribe new definitions, sampling provisions, and test procedures for compressors in a new subpart of DOE regulations. The proposed test procedure would provide instructions for determining the full-load package isentropic efficiency for certain fixed-speed compressors and the part-load package isentropic efficiency for certain variable-speed compressors based on test methods described in International Organization for Standardization (ISO) Standard 1217:2009, ``Displacement compressors--Acceptance tests,'' (ISO 1217:2009). This document also proposes certain modifications and additions to ISO 1217:2009 to increase the specificity of certain testing methods and improve the repeatability of tested and measured values. In this notice, DOE also announces a public meeting to discuss and receive comments on issues presented in this notice of proposed rulemaking.
