Here is an excellent article stating why the entire HVAC and energy efficiency industries need to coalesce around a full system capacity and efficiency performance – 700 Million ACs . It’s from the Washington Post and lays out the rapidly increasing penetration of cooling in emerging markets and what that means for climate change. I hadn’t thought it before in this context but it’s shocking.
In the article US Energy Secretary Ernest Moniz calls for a 25-30% increase in cooling efficiency which he calls “technically feasible”. How about “operationally feasible”? it’s already happening today here in Iowa as well as few other pockets around the country. It’s a simple paradigm shift – stop thinking of an air-conditioner or heat pump as an appliance and start thinking of it as a cooling system. The appliance itself is meaningless until it’s integrated into a air management system that includes a blower, distribution network, and building envelope. The installation contractors and their integration processes are the 25-30% difference when you account for air flow faults across the equipment and through the duct work (not to mention a mis-charge that is masked behind an air flow fault).
Please, NO MORE EXCUSES! Just stop rewarding consumers for not making system holistic buying choices and contractors for not completing system holistic installations.
