🔍 Key Concepts

• Intercooler function in a compressor system (what it cools, and why) • Effect of dust and grease insulation on heat transfer and operating temperature • Relationship between operating temperature, lube oil condition/consumption, and air receiver pressure

💭 Think About

• If the intercooler cannot remove heat effectively because of dust and grease, what happens to the temperature of the compressed air and the compressor parts? • How would higher operating temperatures affect lube oil (thickness, breakdown, leakage, burning off)? • Does fouling on an intercooler surface directly create higher pressure in the receiver, or does it mainly affect efficiency and temperature?

✅ Before You Answer

• Verify how poor heat transfer in an intercooler impacts compressor efficiency and discharge pressure. • Consider whether increased friction or leakage at higher temperatures would make lube oil use go up or down. • Ask yourself if receiver pressure is mainly set by compressor output and control system (unloader, governor, relief valves), not by how dirty the intercooler is.
