A heat pump booster needs the same parameters as a ‘regular’ heat pump. Heat pump

The evaporator temperature is not given as a separate input signal. (as is the case in the regular heat pump) but is propagated in simulation.
In addition, a ‘Primary design heat flow’ and a ‘Primary design regime’ need to be defined. These are quite complex and are easy to make mistakes about. The regime and heat flow to be filled in is the actual heat supplied to the evaporator side with the right regime to supply that heat.
In case this is now known, an assumption for COP and EER can be used to recalculate the evaporator temperature. for example: 200 kW condenser side, at COP = 3 and EER = 4.
200 * 3 / 4 = 150 kW evaporator temperature.
Note that this should always be smaller than condenser side.
