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



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

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
