🔍 Key Concepts

• Intercooler function in a multi-stage air compressor (removing heat between stages) • Effect of higher air temperature entering the next stage on air density and compressor power demand • Typical causes vs. symptoms of unloader problems and water in lube oil

💭 Think About

• What happens to the temperature of the air leaving a dirty intercooler, and how does that change its density before entering the next stage? • If the next stage is compressing hotter, less dense air to the same final pressure, what does that do to the work (power) required? • Which options describe direct consequences of heat removal problems, and which describe failures that usually have other, more specific causes?

✅ Before You Answer

• Be clear on the purpose of the intercooler: what two main benefits does it provide? • Think about whether a dirty intercooler would make the compressor work harder or easier to reach the same discharge pressure. • Eliminate any choices that do not logically follow from reduced heat transfer in the intercooler.
