Question

When charging a low-pressure system, refrigerant should be introduced to the system as a vapor to raise the system's saturation temperature to a minimum of_________.

Answer 1

When charging a low-pressure system, refrigerant should be introduced as a vapor to raise the system's saturation temperature to a minimum of 20 degrees Celsius.

Step-by-step explanation:

When charging a low-pressure system, refrigerant should be introduced as a vapor to raise the system's saturation temperature to a minimum of 20 degrees Celsius. By introducing the refrigerant as a vapor, it allows for more efficient heat transfer in the system. This helps prevent any liquid refrigerant from entering the compressor, which can cause damage and decrease the system's performance.
