How much power does engine cooling system require?

  1. Feb 27, 2015 #1
    How much power do the different engine systems require to operate?

    For example -
    HVAC System - 3kW
    Engine Cooling System - xxkW
    Transmission cooling system - xxkW
    Heated/Cooled seats - xxkW

    Welcome to PF;
    Cooling engines usually involves moving heat from a hot place to a cold place - this will happen without intervention so, depending on the engine, the power requirement can be as low as zero. Assisted cooling can be as simple as blowing air ovet the engine and can be as complicated as you like. The power consumption is basically the cost of pumping the cooling fluid around. You can see that this would be very variable.

    HVAC systems typically have to pump heat from a cold place to a hot place - this requires energy to lower the entropy in the volume being cooled. The minimum energy requirement can often be calculated by thermodynamic considerations but the actual requirement will be higher. Note: Not all HVAC systems run off 3kW.
