摘要：为确保冷水机组压缩机安全运行,在装置运行中设置了低压保护、高压保护、排气温度保护和压差保护等联锁保护,并通过调节冷源出口温度、环境温度对压缩机饱和吸排气温度进行调节。装置运行结果显示:相同饱和吸气温度下,环境温度随着装置负荷的降低、风机转速的增加而升高;装置制冷量随着负荷的增加、饱和排气温度的降低而增大,但其受风速的影响并不大;使用COP对装置性能进行综合评价,COP随着饱和排气温度的升高而降低,此外,在高饱和排气温度下,COP受装置负荷、风速等影响较小,而在低饱和排气温度下,COP随着负荷的增大、风速的降低而增大。
In order to ensure the safe operation of water chiller compressor,some interlock protections including low pressure protection,high pressure protection,exhaust temperature protection and differential pressure protection were set in the device running,and the saturation suction and exhaust temperatures of compressor were adjusted by adjusting the cold source outlet temperature and ambient temperature,the device operation results show that ambient temperature increases with decreasing device load and increasing fan speed under the same saturated suction temperature;the device refrigerating capacity increases with increasing load and decreasing saturation exhaust temperature,while it is not greatly affected by fan speed;COP was used for comprehensive evaluation of device performance and COP decreases with increasing saturation exhaust temperature,in addition,COP is less affected by device load and fan speed at high saturation exhaust temperature,while COP increases with increasing device load and decreasing fan speed at low saturation exhaust temperature.
