Q

If one box in a multiple box, direct expansion type refrigeration system was experiencing an excessively low temperature, this could be a result of which of the following?

🔍 Key Concepts

• Direct expansion refrigeration system operation in a multi-box setup • How refrigerant flow rate affects evaporator (box) temperature • Difference between restricted flow / poor heat transfer vs overfeeding refrigerant

💭 Think About

• For each choice, ask: would this make the evaporator coil absorb more heat (colder box) or less heat (warmer box)? • Think about which options would affect one box only versus the entire system. • Consider what happens to box temperature if refrigerant is allowed to flow more freely than designed to a single evaporator.

✅ Before You Answer

• Verify which conditions would reduce heat transfer at the coil (these usually cause higher box temperatures, not lower). • Check which component, if incorrectly sized or leaking, would affect only that specific box’s expansion/flow. • Confirm whether liquid returning to the compressor would show up as a problem just in one box, or as a symptom in the whole system.
