🔍 Key Concepts

• Effects of moisture inside a closed refrigeration system • How water reacts with refrigerant and oil over time • What happens when water reaches the expansion valve or coldest parts of the system

💭 Think About

• Think about the chemical reaction between moisture, refrigerant, and compressor oil. What kinds of by‑products can form? • Consider what happens to water as it moves through the system and reaches low‑temperature components like the expansion valve. • Ask yourself: could moisture cause only one of the listed problems, or could it reasonably contribute to several of them?

✅ Before You Answer

• Check whether moisture + refrigerant/oil can create acids that damage metal surfaces. • Consider if water in oil at operating temperatures can lead to sludge or deposits in the crankcase. • Think about whether liquid water could freeze and block or restrict flow at the expansion valve area.
