Hi,

I´m trying to generate water to air heat pump parameters using the "WaterAir_PE_Cooling" tool, but i don´t know why the loss-factor is always higher than 0.

I´m using catalog data from different manufacturers, but always the result is the same and the errors are to high.

Can somebody help me showing to me the mistake?

The next link include the file with manufacturer data.
