Textile and fiber industries are major energy consumers and have need to save energy in particular to decrease production costs and increase the competitive power of their products. The cooling and the compressed-air plants in a fiber factory are responsible for air-conditioning and supplying compressed air. The power consumption of the plants accounts for ca. 50% of the total energy consumption of the factory. In this paper, experience in energy saving via operation management of cooling plant for air- conditioning and compressed-air plant in a fiber factory was introduced. Two retrofit projects adopting energy saving techniques were described. They proved quite successful in reducing power consumption of the refrigerating machines and the air-compressors. The fine performance of the systems helped in solving some problems in production as well.
