    compressor power input vs. cooling water massflow in condenser



    Hi everybody
    ..still working my *** off..wondering...and seeking enlightnememt.

    Here is the situation: I have i steady cooling load of 500 kW at evaporator..the compressor pulls 150 kW from the el-net. The cooling water temperature difference through condenser is about 5 Celsius....now, if I reduce the cooling water flow, I will be reducing the refrigerant massflow circulation as well, right..or wrong?..
    Mathematics say Qcondenser=Qcooling water....just want to be sure and comprehend..
    Best regards...Antonio

    Hi Antonio
    You give very general info about the system conditions. If there were named all pressures and temperatures, then it would be a different thing. Given what is given, I would say mass flow decreases, as condensation P increases leading to the ratio head/back absolute pressures increase. Current might also rise ("pulled" kW).
