Abstract: In this paper, the actual operation of the chillers and relative system in a centralized refrigeration station is evaluated. In terms of equipment evaluation, the performance of each chiller is measured online, and through data collation and analysis, the actual cooling capacity and energy efficiency attenuation of each equipment is evaluated by using the methods of qualitative preliminary judgment, horizontal comparison and longitudinal comparison. In terms of system evaluation, based on the measured data and using the method of theoretical analysis, the cooling guarantee rate of the cold source system and the economics of chiller update are studied, and the evaluation suggestions are given.
Keywords: centralized refrigeration station; chiller; operation evaluation; cooling capacity; energy efficiency; cooling guarantee rate; economy;
