A missing condenser fan shroud on a cap tube system will probably lead to what?

A missing condenser fan shroud on a capillary tube refrigeration system will likely lead to higher discharge pressures. The shroud plays a crucial role in directing airflow over the condenser coils, enhancing the efficiency of heat exchange. When the shroud is absent, airflow can become turbulent or insufficient, reducing the heat dissipation from the condenser.

As the condenser struggles to lose heat effectively, the refrigerant remains in the condenser coils for a longer time and can absorb more heat than intended. This increase in heat load causes the pressures within the system to rise, resulting in higher discharge pressures at the compressor. It's important to maintain all components, including the condenser fan shroud, to ensure optimal system performance and efficiency.
