🔍 Key Concepts

• Refrigeration ton – what does “tons of refrigeration” actually measure in terms of heat removal, and how does it relate (or not) to melting ice? • Thermostatic expansion valve (TXV) – what does this valve actually control in a refrigeration system: space temperature, evaporator pressure, superheat, or something else? • Functions of dehydrators/driers and liquid receivers – what each component is designed to do in the refrigerant circuit.

💭 Think About

• Think about which component in a refrigeration system directly senses and responds to the refrigerated space temperature versus what controls refrigerant flow based on conditions at the evaporator outlet. • Consider whether dehydrators are meant to run as an active, adjustable device or if they are a passive component installed for a specific purpose in the liquid line. • Ask yourself what is normally used to remove non‑condensable gases from a system and where those gases tend to accumulate: in the receiver, the condenser, or a separate purge point?

✅ Before You Answer

• Verify the definition of one ton of refrigeration and how it compares to melting a ton of ice in 24 hours. • Confirm what a thermostatic expansion valve actually regulates (hint: look up “superheat control”) and how that indirectly affects box temperature. • Distinguish between a liquid receiver’s purpose (storage and surge volume of liquid refrigerant) and the usual method of dealing with non‑condensable gases (venting/purging at the top of the condenser or high points).

Question 1 of 20

Which of the listed statements is correct concerning refrigeration systems?

Dehydrators must be used continuously in a refrigeration system.

A 25 ton refrigeration system has the same cooling effect as melting 25 tons of ice in 24 hours.

A thermostatic expansion valve is used to control refrigerated space temperature.

The liquid receiver functions to collect and remove non-condensable gases.
