Title: Research oh Energy-saving Strategy for Partial Load Operation of Multi-uults Air-conditioning System
Abstract: Since water chiller unit may experience the part-load operation on most occasions,a energy-saving method that group water chiller systems were connected in a parallel style was proposed.Model simulation and experiments were carried out to test the improvement. Experimental results showed that,decrease of the part load ratio from 100% to 50% caused 9.5% increase in COP,decreases of condensing temperature from 47.2℃to 42.5℃,increases of evaporating temperature from 2.2℃to 3.5℃.COP had been enhanced by 9.5%.That indicated that this strategy exist a grate potential for performance enhancement of multi-units air-conditioning system operating under partial losa.Meanwhile,We analyzed the reason why there's the difference between simulation and experiments,and we further proposed a measure to manage this.
