What happens if the testing gas is not properly removed from a refrigerant system?

When testing gas is not properly removed from a refrigerant system, it can indeed lead to increased pressure within the system. This phenomenon occurs because the testing gas can mix with the refrigerant, which alters the overall pressure and can cause it to elevate beyond normal operating levels. Elevated pressure can result in various issues, including increased wear and tear on system components, potential failures of seals and valves, and a higher risk of leaks.

Properly evacuating any testing gas ensures that the refrigerant system operates efficiently and within specifications. If the system pressure remains above the designed limits, it can also impact the cooling capacity and overall efficiency of the system, leading to suboptimal performance and increased energy consumption. Managing the pressure correctly by fully removing any testing gas is crucial for the reliability and longevity of the refrigeration system.
