Which outcome arises from using a scroll compressor pump without internal oil separator in a refrigeration system?

💡 Explanation

When an oil separator is absent, excessive oil circulation occurs because the refrigerant carries oil throughout the system, resulting in substantial oil accumulating on the internal surfaces of the evaporator, hindering heat transfer. Therefore decreased cooling capacity occurs, rather than increased efficiency, temperature reduction, or increased lifespan; these would need specific oil management measures and alternative lubrication strategies.
