Midea requests that DOE permit Midea to test the basic models listed in its petition using the alternate test procedure in the interim waiver granted to LG Electronics USA, Inc. ("LG") on June 29, 2018, which requires testing units at four rating conditions instead of a single rating condition and calculating each test unit's weighted- average combined energy efficiency ratio ("CEER"), which is comp
