Ambient temperature vs. air on core (AOC) temperature
This paper aims at differentiating between the ambient temperature vs. air-on-core (AOC) method of rating the performance of a cooling system used on a generator set.
Free QuoteIn high-altitude areas, due to low air density, the heat dissipation rate is much slower than at sea level, causing the engine to maintain high temperatures for a period of time. If the diesel generator set is used indoors, we should ensure that it has sufficient fresh air.
At higher values, the average loss of power is generally of 3% for 500 m of elevation. Generally, temperature affects generator engines starting at 40ºC. Above this ambient temperature: The air is already very hot and its quality is no longer optimal to generate good combustion when mixed with fuel. This generates loss of power.
When exposed to elevated temperatures, generators may struggle to convert fuel into electrical energy efficiently. This means the generator may require more fuel to produce the same amount of power, leading to increased operating costs. Elevated temperatures can accelerate wear and tear on generator components.
Temperature, like altitude, is another significant environmental factor that directly affects generator set performance. Temperature's influence is multifaceted, impacting air density, engine component temperatures, lubrication effectiveness, and cooling system efficiency.

Generator Dreating in Conditions of AltitudeGenerator Performance at High TemperaturesGenerator Derating Ambient TemperatureThe Importance of Having ForesightAs far as the alternator is concerned, it is also affected by high temperatures. The majority of manufacturers guarantee the power of their alternators, as long as they operate at an ambient temperature of below 40°C. At higher values, the derating in an alternator is generally of 3% for each additional 5º C.See more on genesalenergy Author: Genesalinmab [PDF]
