What is a consequence of excessive moisture in a refrigeration system?

Excessive moisture in a refrigeration system can lead to system freezing and blockage. Water in the system can combine with refrigerant oil to form ice, which can accumulate at critical junctures such as expansion valves or evaporators. This ice buildup can obstruct the flow of refrigerant, leading to reduced efficiency and a potential inability to adequately cool or heat the designated area.

Blockages from ice or other moisture-related deposits can also elevate pressure within the system, potentially causing more severe issues like compressor failure or system shutdown. The presence of moisture introduces complications such as corrosion, which can damage components over time, further complicating the refrigerant cycle and leading to increased maintenance costs.

Therefore, managing moisture levels within a refrigeration system is vital for ensuring reliable operation and longevity of the equipment.
