Why is it important for refrigerant entering the compressor to be 100% dry vapor?

• A. To enhance cooling capacity
• B. To prevent flooding within the evaporator
• C. To avoid compressor damage
• D. To maintain system efficiency

Answer: (C)

It is crucial for refrigerant entering the compressor to be 100% dry vapor to avoid compressor damage. Compressors are designed to compress gaseous refrigerants, and if liquid refrigerant enters the compressor instead, it can lead to hydraulic shock or liquid slugging. This condition can cause significant wear and tear on the compressor components, resulting in mechanical failure. Liquid refrigerants lack the necessary properties for proper lubrication and can cause erosion or damage to the compressor’s internal parts. Thus, ensuring that only dry vapor reaches the compressor helps protect it from potentially catastrophic failures and extends the lifespan of the equipment. Maintaining this condition is vital for reliable operation and maintenance of the refrigeration system.
