What could a constant high discharge temperature indicate in an air conditioning system?

• A. Low refrigerant level
• B. Overcharging with refrigerant or a failing compressor
• C. Blocked air filter
• D. Dirty condenser coils

Answer: (B)

A constant high discharge temperature in an air conditioning system can indeed indicate overcharging with refrigerant or a failing compressor. When the system is overcharged, there is too much refrigerant in the system, which can lead to inadequate heat transfer. This scenario causes the discharge temperature to rise because the compressor has to work harder to circulate the excessive refrigerant. Additionally, if the compressor itself is failing, it may not compress the refrigerant effectively, leading to higher discharge temperatures as well. Understanding this condition is crucial for troubleshooting and maintaining optimal system performance. It is essential to monitor discharge temperatures to prevent potential damage to the compressor and maintain energy efficiency. Hence, identifying overcharging or compressor failure as a cause is vital for proper system diagnostics and corrective measures.
