Question: 1 / 400

Air or non-condensable gases in a capillary tube air conditioning system typically cause which conditions?

High oil level

Air or non-condensable gases in a capillary tube air conditioning system typically cause high oil level.

When air or non-condensable gases enter the system, they can cause the compressor oil to foam up and circulate abnormally. This leads to a high oil level in the system, which can disrupt proper lubrication of the compressor components and reduce the system's efficiency.

The other options are not the typical conditions caused by the presence of air or non-condensable gases in a capillary tube air conditioning system. High suction pressure and high discharge pressure, low suction pressure and low discharge pressure, and low operating pressures are not directly related to the presence of air or non-condensable gases in the system.
