Hello,
is it possible to modeling an Air-To-Water Heat Pump with type 668? When I
am set the source specific heat to 1.005 (Air)? Or is there a better way to
modeling an Air-To-Water Heat Pump with any other Type form the Tess library
V2.0 ?
Kind regards,
Julian
Julian,
You can use 668 to model an air-to-water heat pump. The component is
documented in such a way that the "heating on" control signal condition
means that it should heat /air /and that the "cooling on" control signal
condition means that it should cool the /air/. However, if you just
interpret those signals the other way such that "heating on" means that
it should cool the /water /and "cooling on" means that it should heat
the /water /then you're modeling an air-to-water instead of a
water-to-air heatpump.
I don't recall whether Type668 has any desuperheater or auxiliary
heater features but if it does then you should disable those I think.
best,
David
