[TRNSYS-users] yousing Type 668 Water to Water Heatpump to Model a Air to Water Heat pump?

[David BRADLEY]

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
