🔍 Key Concepts

• Water regulating valve operation in a water‑cooled condenser (what variable is it trying to keep constant?) • Difference between refrigerant side (gas in, liquid out) and water side (water in, water out) of the condenser • Where a sensing bulb should be placed to best reflect condenser performance and compressor protection

💭 Think About

• Ask yourself: Is the valve trying to control water flow based on water temperature or on refrigerant condensing temperature/pressure? • Which line coming from the condenser tells you whether the refrigerant has been properly condensed to liquid? The hot gas entering, the liquid leaving, or the cooling water? • If you wanted the system to respond quickly to high condensing temperature and protect the compressor, which location would give you the most direct and stable temperature signal?

✅ Before You Answer

• Be clear whether the bulb must sense the refrigerant or the cooling water—only one of those directly indicates condensing conditions • Identify which side of the condenser has high‑temperature superheated gas and which has sub‑cooled liquid refrigerant—this affects sensor accuracy and stability • Choose the point where temperature change most directly reflects overall condenser effectiveness, not just incoming cooling water conditions
