Energy Conservation Program for Certain Industrial Equipment: Decision and Order Granting a Waiver to Mitsubishi Electric and Electronics USA, Inc. From the Department of Energy Commercial Package Water-Source Heat Pump Test Procedure

Riepilogo

This notice publishes the U.S. Department of Energy's (DOE) Decision and Order in Case No. CAC-015, which grants a waiver to Mitsubishi Electric and Electronics USA, Inc. (Mitsubishi) from the existing DOE test procedure for commercial package water-source heat pumps. DOE is granting this waiver because these water-source multi- split heat pumps, like the air-source multi-split heat pumps that have been granted similar waivers, are too complex to test using the DOE test procedure. As a condition of this waiver, Mitsubishi must test and rate the energy consumption of the water-source WR2 and WY series models (from its CITY MULTI Variable Refrigerant Flow Zoning line of commercial package heat pump equipment) according to the alternate test procedure set forth in this notice.
