What is the role of the nitrogen holding charge during installation?

The nitrogen holding charge plays a significant role in maintaining the cleanliness of the refrigeration system during installation. When systems are being installed or transported, they can be exposed to contaminants such as moisture, dust, or debris. A nitrogen holding charge helps to displace air and moisture inside the system, thereby preventing oxidation and contamination of internal components. This inert gas creates a protective atmosphere, ensuring that the system remains clean until it is ready for operation.

While there are other factors to consider during installation, such as leak testing or system pressurization, the primary function of the nitrogen holding charge specifically focuses on safeguarding the internal environment of the equipment. This is crucial for the long-term reliability and efficiency of the refrigeration system, as contaminants could lead to corrosion or other operational issues once the system is put into service.
