🔍 Key Concepts

• Capacity control system on a water-cooled rotary chiller (what it is trying to regulate) • Relationship between chilled water temperature and chiller loading/unloading • How the illustration labels each thermistor and shows its connection to the loader solenoid valves

💭 Think About

• Ask yourself: Which temperature does the control system care about most when deciding to increase or decrease compressor capacity—refrigerant gas temperature or chilled water temperature? • Look at the diagram paths: Which thermistor symbol is wired or referenced closest to the loader (capacity) control section and its solenoid valves? • Is capacity control based on protecting the compressor from overheat, or on maintaining the desired outlet temperature of the medium being cooled?

✅ Before You Answer

• Verify in the legend which symbol corresponds to each thermistor location (suction gas, discharge gas, chilled water in, chilled water out). • Trace from the loader control / minimum load control valve area to see which thermistor is functionally tied into that control loop. • Confirm which thermistor would best represent the actual cooling effect delivered to the system, not just internal compressor conditions.
