[TRNSYS-users] TYPE 402: Compressor Heat Pump Including Modulation

[Mahach, Hassan]

Dear  TRNSYS Colleagues,

We are working with TYPE 402 for modeling a heat pump including modulation, in this Type, we have to create eight coefficient that characterize the behavior of the each specific heat pump as you can see in the file attached (Type402_PQ.dat). The latter is created using the manufacturer data (please see WP_Daten.txt) in which the condenser heating power and compressor electrical power are set it for different modulation coefficients (I think we can called it like this..) (please see A3 Y_n[[-]] column 5 in WP_Daten.txt file )  for the same condenser & evaporator temperatures

In the manufacturer data, we don't have these "modulation coefficient", have only one value for the condenser heating power and compressor electrical power for each condenser & evaporator temperatures

My question: how these coefficients are defined and how we can adjust the condenser heating power and compressor electrical power for different modulation coefficients?

Thank you for your cooperation
Best regards
Hassan
