随着我国冷库建设技术的不断发展,各种自控装置在冷藏库中得到了广泛的应用。然而,一些老冷库由于受到现有条件、投资费用等方面的限制,要实现全自动控制比较困难,但是,某些局部自控回路的采用还是可行的,如:氨压缩机的自动加油。由于它具有投资较少,安装方便,效果理想等优点,所以,应用于任何冷库都是可取的。 With the continuous development of cold storage construction technology in our country, various automatic control devices have been widely used in cold storage. However, some old refrigerators are difficult to be fully automatic controlled due to the limitations of existing conditions and investment costs. However, the use of some local self-control circuits is still feasible, such as the automatic refueling of ammonia compressors. Because it has the advantages of less investment, convenient installation and good effect, it is advisable to apply it to any refrigerator.
