Q

The purpose of chill shocking an evaporator is to __________.

🔍 Key Concepts

• Refrigeration evaporator operation and what happens to scale when metal surfaces rapidly change temperature • How thermal shock affects brittle deposits versus metal tubing • Normal methods used to prepare, test, or maintain pressure vessels and heat exchangers

💭 Think About

• Ask yourself: When engineers use a sudden temperature change on tubes, are they usually trying to change the metal’s properties, remove something from the surface, or check its strength? • Think about what scale or mineral deposits do on hot/cold surfaces. How would a sudden change in temperature help with maintenance? • Which of the options would more likely require controlled, gradual procedures rather than a sudden temperature shock?

✅ Before You Answer

• Compare which answer choices are about cleaning/maintenance versus testing or altering metal properties • Remember that hydrostatic tests and leak tests typically involve pressure and water, not just temperature changes • Consider whether stress relieving metal is normally done with rapid temperature changes or carefully controlled heating and cooling over time
