Why should short cycling of the compressor be avoided during the charging of the refrigeration system?

Short cycling of the compressor in a refrigeration system refers to the compressor frequently starting and stopping in a short time frame. This behavior should be avoided because it places significant stress on the compressor motor.

When a compressor starts, the motor draws a high inrush of current, which can lead to overheating if the unit does not have adequate time to run and cool down before it cycles off again. Constantly starting and stopping can also lead to some mechanical wear and tear on the compressor components, resulting in premature failure.

Furthermore, short cycling can cause inefficiencies in terms of energy consumption, as the motor is working harder and less efficiently than it would in a more stable operating cycle. By allowing the compressor to run uninterrupted for longer periods, it can operate more efficiently and avoid the overheating issues associated with frequent starts and stops. This practice is essential for ensuring the longevity and reliability of the refrigeration system.
