What occurs when a refrigeration system is flushed incorrectly?

• A. Improved efficiency
• B. Reduction in temperature
• C. Possible compressor damage
• D. Increased refrigerant flow

Answer: (C)

When a refrigeration system is flushed incorrectly, it can lead to possible compressor damage. Flushing is the process of removing contaminants, debris, or old oil from the system to ensure that the new refrigerant can operate efficiently. If not done properly, residues can remain inside the system, or flushing agents themselves can cause harm.

Specifically, if improper flushing techniques are used, debris may be forced into the compressor, impairing its functionality and potentially causing mechanical failure. Additionally, incorrect flushing can result in the introduction of unsuitable oils or solvents that can break down the lubricating properties needed for the compressor to function smoothly, leading to overheating and eventual damage.

In contrast, the other outcomes listed are typically the result of a well-functioning system or unrelated to the flushing process. Improved efficiency and reduction in temperature typically come from proper maintenance and operation, while increased refrigerant flow is usually a separate issue unrelated to incorrectly flushing the system.
