4.1 氨制冷系统自控设计要点氨制冷系统自控设计应符合如下要求: 1、必须确保制冷装置运行的安全可靠性。 2、为保证食品在冷藏期间的质量,在局部自控和半自控系统中应优先考虑库房温度控制,以保持库房温度的稳定性。 3、自控系统应着重考虑对机器设备台数多,系统复杂,操作比较频繁和操作条件较差的装置,以提高工作效率,改善劳动条件。 4、在保证工艺合理要求的前提下,应尽量简化制冷装置和系统,以减少自控元件,
4.1 Ammonia refrigeration system design control points Ammonia refrigeration system design should meet the following requirements: 1, you must ensure the safety and reliability of refrigeration equipment. 2, in order to ensure the quality of food during cold storage, partial automatic control and semi-automatic control system should give priority to warehouse temperature control, in order to maintain the stability of the warehouse temperature. 3, automatic control system should focus on considering the number of machines and equipment, the system is complex, more frequent operation and poor operating conditions of the device to improve work efficiency and improve working conditions. 4, in ensuring the reasonable process requirements, should try to simplify the refrigeration equipment and systems to reduce the control components,
