根据现场考察和交流,介绍分析了英国某冷库氨制冷系统的若干新技术。通过采用减少系统充氨量的系列新技术,可以使系统的充氨量大大减少,安全性大大提高。通过采用自动控制、按需除霜、回收余热加热地坪、冷风机合理配置等新技术,可以明显提高运行的能效。
According to the on-site inspection and exchange, this paper introduces and analyzes some new technologies of a refrigeration ammonia refrigeration system in the UK. By using a series of new technologies to reduce the amount of ammonia charge in the system, the amount of ammonia charge in the system can be greatly reduced and the safety greatly enhanced. Through the use of automatic control, on-demand defrosting, recovery of waste heat heating floor, a reasonable allocation of chillers and other new technologies, can significantly improve the energy efficiency of the operation.
