What happens when there are leaks in the gasket or fittings of a low-pressure system?

When there are leaks in the gasket or fittings of a low-pressure system, air and moisture can enter the system. This is a critical concern because the presence of moisture can lead to the formation of acids within the refrigerant, which can damage the system components. Moreover, air, which is not a condensable fluid, can disrupt the refrigeration cycle, leading to inefficiencies and potentially causing the compressor to operate improperly.

The introduction of moisture into the system can also result in other issues, such as the formation of ice in the expansion valve or evaporator, which may block refrigerant flow. This can lead to significant reductions in system efficiency and performance.

Maintaining the integrity of the gaskets and fittings is vital for ensuring the system operates effectively and for prolonging the life of the equipment. It's essential for technicians to identify and repair any leaks promptly to prevent air and moisture infiltration into low-pressure systems.
