I wonder what the efficiency is at higher temperature differences.
For example, I would like a water-sourced aircon which cooled a radiant or chiller circulating system on the cold side, while heating incoming water for hot water on the hot side (plus an 'overflow' cooling ground loop if necessary). Maybe this isn't beyond the ability of current systems, but I think having a fairly large gap of 60C hot/5-15C cold is inefficient currently, and maybe a reason you don't see this obvious setup too often.
- micro_cam 4y agoA standard heat pump water heater does that but will only provide a couple degrees of cooling to meet standard domestic hot water needs. You can also get pool heater heads for heat pumps/ac units though last time I looked not all were available in the us.
- jacknews 4y agoYes that's a great idea. When I said 'overflow ground loop', I obviously I meant 'dump any excess heat into your swimming pool'. In fact this surely makes sense for existing aircon, just for better efficiency.
