What should be done after determining the proper amount of superheat from a chart?

After determining the proper amount of superheat from a chart, it is essential to measure the total superheat and compare it to the amount needed. This step is crucial because superheat is a key indicator of the refrigerant's state and system performance. It ensures that the refrigerant entering the compressor is fully vaporized, which helps prevent compressor damage due to liquid refrigerant carrying over.

By measuring the total superheat, a technician can confirm whether the system is operating within the desired parameters. If the measured superheat is higher or lower than the required level, it may indicate issues such as insufficient refrigerant, restrictions in the system, or improper expansion valve operation. This comparison allows for further troubleshooting and adjustments necessary to optimize system efficiency and reliability.
