    Experimental Data Help



    Dear Friends,

    I am working on to design a model based controller for a heat pump which is used to provide domestic hot water. I created a mathematical model for the condenser heat transfer. My aim is to control the refrigerant flow and obtain desired hot water temperature in my design. However, I need some experimental data to run my simulation which is created in Simulink. Unfortunately, I don't have any opportunity to conduct an experiment in a laboratory.

    Is there any source to provide the refrigerant (R134a) mass flow rate from evaporator and temperature of refrigerant at the outlet of condenser during start-up process of the heat pump until obtain 60 oC water outlet ?

    Thank You for your help and support in advance...

    In an air/water heat pump, the condenser transfers it's heat to the water circuit, so the refrigerant mass flow and heat transfer will vary with the heating circuit temperature. It's not a constant process.

    Dear Frank,

    I am totally aware of it and that's why I need some experimental measurement data as a function of time.

    Dear Friends,

    I am trying to find a transient system behaviour of a heat pump briefly.. Isn't there anybody to help out ?

    Regards,
