🔍 Key Concepts

• Condenser function in a refrigeration cycle and what happens if it cannot reject heat effectively • How head pressure (discharge pressure) is related to condenser temperature and cooling medium (water or air) conditions • Effects of refrigerant charge being too low or too high on system pressures

💭 Think About

• Think about which choice would make it harder for the condenser to get rid of heat to the cooling water or air, and what that would do to discharge (head) pressure. • For each option, ask yourself: would this condition tend to raise the discharge pressure, lower it, or mostly affect suction pressure? • Consider which components mainly influence discharge (high-side) pressure versus which primarily influence suction (low-side) pressure.

✅ Before You Answer

• Identify which options mainly affect the high side (condenser) versus the low side (evaporator) of the system. • For each option, picture the heat flow path: compressor → condenser → expansion valve → evaporator, and decide where the problem acts. • Verify which conditions would more likely cause low head pressure rather than high head pressure, and eliminate those.
