🔍 Key Concepts

• Effect of condenser cooling water flow on condensing pressure and overall system pressures • How non‑condensable gases (air) in the system affect pressures and temperatures • Relationship between refrigerant charge level (too much vs too little) and compressor suction/head pressures

💭 Think About

• First, think about what would generally make the compressor discharge (head) pressure drop: is it usually from removing heat too well, not removing enough heat, or from not having enough refrigerant to compress? • Consider what air in the system usually does to condenser pressure and temperature — does it tend to increase or decrease system pressures? • For each option, imagine the pressure gauge readings: What would happen to suction pressure and discharge pressure if that condition existed?

✅ Before You Answer

• For each choice, decide whether it would make condenser/receiver pressure go up or go down, and whether that matches "low head pressure" • Check your refrigeration fundamentals: too much cooling vs too little cooling at the condenser — which one drives condensing pressure lower? • Remember typical symptom patterns: overcharge vs undercharge of refrigerant and the usual direction of suction and discharge pressure changes
