Fault diagnosis and transformation of cool storage system in a pharmaceutical factory

In view of the characteristics of the water cool storage air conditioning system and some difficulties and key technologies existing in the engineering design and operation process, combined with an actual engineering project of cool storage transformation system in a pharmaceutical factory, according to the on-site diagnosis and analysis results, the specific measures for the energy saving transformation of equipment, the automatic control transformation of transmission and distribution system and terminal equipment, and the optimization of water distribution system and water distributor are proposed in this paper. The lack of technologies of small height-to-diameter ratio reservoir distribution temperature layer control and large temperature difference temperature and humidity independent control at the clean end is mainly discussed. The results show that the energy efficiency of the system is greatly improved after the transformation, and the annual operating cost of cooling is reduced by 1.410 3 million yuan compared with that before the transformation, which achieves the double benefits of cost saving and energy saving.
