What is the condenser outlet pressure noted under abnormal conditions?

• A. 75 PSIG
• B. 100 PSIG
• C. 181 PSIG
• D. 26 PSIG

Answer: (C)

The condenser outlet pressure under abnormal conditions typically indicates the pressure at which the refrigerant exits the condenser before entering the expansion device or evaporator. This pressure can vary based on factors such as ambient temperature, the efficiency of the condenser, and operating conditions within the refrigeration system. In the context of various refrigerants and typical operating conditions in industrial refrigeration systems, a condenser outlet pressure of 181 PSIG suggests a high operating pressure that is compatible with common refrigerants used in industrial applications, such as ammonia or certain HFCs, under certain loading conditions. This elevated pressure is generally associated with the need to remove heat at higher temperatures in an effective manner, especially when the system is under heavy load or experiencing issues such as elevated ambient temperatures or reduced condenser efficiency due to fouling or lack of adequate cooling water flow. Understanding the nuances of pressure readings can help operators identify potential problems. If the pressure is significantly higher or lower than expected, it may indicate issues with the system that could lead to inefficiencies or equipment failures. Therefore, noting and maintaining the proper outlet pressure is crucial for the reliable operation of refrigeration systems. Other provided pressures may not reflect typical conditions for a condenser; for instance, a pressure of 75 PSIG or 100 PSIG could
