Final answer:
The most common way to clean compressor blades is by injecting detergent into the compressor air intake, as it can be done without disassembly and operational downtime. Other methods like Teflon coating are not for cleaning, but for protection. Comprehensive air system cleaning may be necessary in some cases, involving a full maintenance program.
Step-by-step explanation:
The most common method of cleaning compressor blades is injecting detergent into the compressor air intake. This process involves using a cleaning fluid that is atomized and sent through the compressor during operation or at a halted condition, depending on the compressor design and maintenance procedure. It effectively removes dirt, oil, and other contaminants from the compressor blades without the need for disassembly.
In comparison to the other methods listed, Teflon coating the blades is not a cleaning method, but rather a preventative measure to resist fouling and corrosion. Soaking the rotor in detergent might not be practical for large compressors, and opening the compressor and spraying the blading may require extensive downtime and disassembly.
In the case of comprehensive system cleaning, such as those following infections or contamination, a thorough cleaning and maintenance program is crucial. This might involve cleaning components like an air conditioning cooling tower to prevent the growth of biofilms that could harm the system's efficiency and health standards.
