Can the brine heat pump database be updated with new heat pumps?

Is it possible to create your own heat pump model?

The default heat pump model currently is giving vert incorrect results for COP and brine loop temperatures.

Thank You!

Sorry for the delay of the answer.

No, these possibilities only excist in IDA ICE.

I could make birne pump correct results by adjusting "birne to water heat pump" with "heat exchange with given temperature source" by changing source givent temperature. But with ambient heat exchange source changing any parameter COP I could not achieve. What algorithms are intended for ambient heat exchange heat pumps to achieve COP and power?

It's possible to change the model. By right click on the model name and select open you can change the parameters of the model. Then you can save it in the database. However chnaging the COP value or heat rejection P_H don't change the result in a correct way if you don't change the polynoms in the model. The polynoms are the model!
