What might cause uneven temperature distribution in a refrigeration system?

Uneven temperature distribution in a refrigeration system can often be attributed to insufficient airflow. In a refrigeration system, proper airflow is essential for effective heat exchange, as it helps to distribute the cooler temperatures evenly throughout the space being cooled. When airflow is restricted, it may be due to factors such as dirty filters, blocked vents, or issues with fans, leading to various parts of the refrigeration system cooling at different rates. This results in some areas being effectively cooled while others remain warmer, thereby causing an uneven temperature distribution.

In contrast, while overcharged refrigerant may lead to excessive pressure and potentially affect the system's efficiency, it doesn't directly cause uneven distribution of temperature but rather impacts the overall operation. Leaking refrigerant lines can reduce the overall capacity of the refrigeration system and may lead to warmer temperatures, but this effect is more about total cooling capacity than localized uneven temperatures. High ambient temperatures can affect the system's ability to maintain desired temperatures overall but wouldn't cause specific unevenness in cooling distribution within a space.
