How much power does engine cooling system require?

Click For Summary
SUMMARY

The power requirement for engine cooling systems varies significantly based on the engine type and cooling method employed. While some systems may operate with minimal power, others, particularly those utilizing assisted cooling techniques, can demand substantial energy. The HVAC system typically requires around 3kW, but this figure can fluctuate based on specific configurations and operational conditions. Understanding the thermodynamic principles behind these systems is crucial for accurate power consumption assessments.

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.
