Pharmaceutical industry is a high-tech industrial group with highly integrated multi-disciplinary advanced technology and means, involving national health, social stability and economic development. At present, the national energy saving and emission reduction policies put forward higher requirements for some equipment and production conditions of pharmaceutical enterprises. How to reduce energy consumption as much as possible under the premise of meeting production requirements has become a headache for many pharmaceutical enterprises. In this kind of enterprise, the usage rules of various equipment are different, and the running time is different. Some equipment runs 24 hours a day and 365 days a year, while others need to run regularly. Compared with other industries, pharmaceutical factories have higher requirements for steam system, and their share of energy consumption in enterprises is larger.
