Overheating,It's a simple problem really. If you understand percentages - and I know you do, then overheating problems are easy to get a handle on.You see, it's a balancing act between the percentage of input power lost to heat and the percentage of heat dissipated by the system - mainly the heat exchanger.Take a system with an input power of 100 kilowatts.If it's 80 percent efficient, it's creating 20 kilowatts of heat load.If the exchanger is dissipating 20 kilowatts of heat then a stable operating temperature will be maintained.If the system starts to overheat, then either:
The system is no longer 80 percent efficient; or
The exchanger is no longer dissipating 20 kW of heat.
