What’s new in AC 2020?
I am wondering if any of our esteemed editors or contributors have attended the recent 2020 AHR Expo?
Any new products to discuss? Any heat pumps for residential use?
I didn’t go to the conference myself, but, I know that Mestek has been testing a new SpacePak Air to Water Heat Pump: a Split System Inverter Air- to-Water Heat Pump. Similar in spirit to standard air-to-refrigerant systems. They announced this in 2019, and it is coming to market this year apparently. It seems like the performance is not that competitive with state of the art ASHP design (COP 2.66 at 95 deg outdoor air temperature and 50 degree water temperature), although, I suppose performance isn’t everything.
