What problem can non-condensables cause in a refrigeration system?

• A. Low discharge pressure
• B. High discharge pressure
• C. Increased efficiency
• D. Cooling system leaks

Answer: (B)

Non-condensables, such as air or other gases that do not condense under the operating conditions of the refrigeration system, can lead to high discharge pressure. This phenomenon occurs because non-condensables take up space in the condenser, preventing the refrigerant vapor from fully condensing into a liquid. As a result, the compressor has to work harder to pump the refrigerant, leading to increased pressure within the system. When non-condensables are present, they disrupt the normal operating conditions of the refrigeration cycle, which obliges the compressor to exert more energy to achieve the necessary pressure to circulate the refrigerant. This situation not only causes inefficiencies but also stresses the components of the system, potentially leading to mechanical failures over time. Understanding the impact of non-condensables is critical for maintaining the efficiency and effectiveness of refrigeration systems. It's important to regularly check for and remove any non-condensable gases to ensure optimal performance and longevity of the system.
