摘要：

为探究离心式空压机预处理后入口参数对整体能耗的影响,根据某纺织厂空压站具体情况,在入口空气经组合式空调机组处理后,分别对不同温、湿度环境下离心式空压机运行时的能耗,以及预处理装置提供冷量所产生的能耗进行实测分析。分析数据表明:从空压机及预处理系统整体耗能的角度出发,在吸气含湿量不变,进气温度降低8 ℃左右时,整体耗能较小;在吸气温度保持不变,含湿量约为15.0 g/kg时,整体能耗达到最低值。结果认为:控制好空压机预处理后的吸气参数,可以有效降低空压机及预处理系统整体能耗。

Abstract:

To investigate the impact of the suction parameters of the centrifugal air compressor pretreatment on its overall energy consumption, according to the actual condition of the air compressor station in a textile factory, after the inlet air was processed by the combined air conditioning unit, an actual measurement analysis was performed on the energy consumption of the running centrifugal air compressor under different temperature and humidity environment and the energy consumption generated by the pretreatment unit corresponding to the cooling capacity. Through data analysis, it was found that: in view of the overall energy consumption of the air compressor and the pretreatment system, when the suction moisture content remained the same and the inlet temperature was reduced by about 8 ℃, the overall energy consumption was small; when the suction temperature remained unchanged, with a moisture content of about 15.0 g/kg, the overall energy consumption reached the minimum value. The results show that through controlling the suction parameters of the air compressor after pretreatment, the overall energy consumption of the air compressor and the pretreatment system can be effectively reduced.

Key words: centrifugal air compressor, pre-treatment, power consumption, suction temperature
