🔍 Key Concepts

• Effect of refrigerant overcharge on system pressures • Role of the condenser and cooling water in removing heat from the refrigerant • Purpose of the high-pressure cut-out safety control

💭 Think About

• First, think about what happens inside the system when there is too much refrigerant: how does that affect condenser pressure and volume available for condensation? • Look at which options actually change the amount of refrigerant in the system versus which only change operating conditions temporarily. • Consider which actions are meant as troubleshooting corrections and which are meant only as safety limits that should not be raised to ‘fix’ a problem.

✅ Before You Answer

• Identify which choice directly addresses the root cause (too much refrigerant) instead of only masking the symptom (high pressure). • Check whether changing cooling water flow would truly correct an overcharge, or just temporarily influence condenser temperature and pressure. • Confirm that safety devices like the high-pressure cut-out are not meant to be adjusted upward to work around a real fault condition such as overcharge.
