Strength Test

Strength Test data from EN 14511 can be used in the calculations. The model provides default values to recalculate the test points to fit the part load of the heat pump for the different kinds of heat pumps (fixed capacity, staged capacity och variable capacity). The capacity and corresponding COP values are then interpolated between the temperature bins. However, the accurateness of the recalculation is unknown.  
The model itself has suggested test points with a radiator curve (supply temperature) that is adjusted to the outdoor temperature. At colder outdoor temperatures the supply temperature is higher and at warmer outdoor temperatures the supply temperatures are lowe
