🔍 Key Concepts

• How a thermostatic expansion valve (TXV) uses its sensing bulb charge to control refrigerant flow • The difference between a bulb that has the same refrigerant as the system versus a different refrigerant inside it • Standard industry term used when the sensing bulb’s charge is intentionally different from the system charge to shape the superheat curve

💭 Think About

• Ask yourself: what is the purpose of using a different fluid in the sensing bulb compared with the main system refrigerant? How does that affect superheat control? • Look at the root words in the options (mixed, cross, straight, blended). Which one best describes a deliberate design choice where two different refrigerants/charges are used together in one control arrangement? • Think of common HVAC/R terminology: which of these terms is actually used in textbooks and manufacturer literature to describe a TXV bulb charged with a different refrigerant than the system?

✅ Before You Answer

• Verify which term is commonly used in refrigeration and air‑conditioning manuals for a valve whose bulb contains a different charge than the evaporator refrigerant • Eliminate choices that sound like generic English words but are not standard TXV charge classifications • Confirm that the correct term is associated specifically with the power element (sensing bulb and diaphragm assembly) of the TXV, not the entire system charge
