| Summary: | 碩士 === 崑山科技大學 === 機械工程研究所 === 97 === Reciprocating hermetic compressors have been known since the 19th century and, due to their simplicity and flexibility when working in a wide range of conditions, they are still used nowadays in industrial, refrigeration and air conditioning systems. Many air compressors may be running at efficiencies as low as 10 percent. Compressed air is one of the most expensive sources of energy in a plant. Improving air compressors efficiency can yield significant savings to your facility.
The air compressor performances test laboratory was established. Three 10HP air compressors were tested. The air flow rate, volume efficiency, adiabatic thermal efficiency, and energy consumption ratio were compared under various exhaust pressures. The test results showed that the performance for brand A air compressor is best of the three compressors. The variation of efficiency is over 10%, so the test of air compressor is necessary for energy economic.
