ATLANTIC CITY, NJ — What’s better, 12 or 13 SEER? Many in the industry have offered their opinions. Now the engineers have voiced theirs.
The symposium “Methods and Effects of Improving Efficiency of Unitary Equipment to Meet New Energy Efficiency Requirements,” held at the 2002 American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Winter Meeting, discussed the cost and benefit tradeoffs of moving to 12- or 13-SEER equipment, and described an improved heat pump design and modulating blower/compressor strategies for comfort control.
