Describe one way to increase the efficiency of a refrigeration system.

Increasing the efficiency of a refrigeration system can be effectively achieved by regularly cleaning coils and checking refrigerant levels. Over time, dirt and debris can accumulate on the coils, which impairs heat exchange. When coils are dirty, the system has to work harder to remove heat from the refrigerant, consuming more energy and reducing overall efficiency.

By keeping the coils clean, the system can operate more optimally, allowing for better heat transfer and less energy consumption. Regularly checking refrigerant levels is also crucial because the efficiency of the refrigeration cycle is directly related to the correct amount of refrigerant present. An undercharged system can lead to reduced cooling capacity and increased energy usage, while an overcharged system can also cause inefficiencies and potential damage. Therefore, maintaining clean coils and proper refrigerant levels ensures that the refrigeration system runs smoothly, efficiently, and reliably.
