磁悬浮离心式冷水机组节能潜力及其经济性分析OA北大核心CSTPCD

In order to effectively evaluate the advantages of maglev chiller in terms of energy saving and economic performance,the energy consumption model and life cycle cost(LCC)model were established,then the effect of energy saving and economics of the maglev chiller were stuided.The research results show that the maglev chiller saves about 30%of energy and reduces carbon emissions by 1.7×105～1.8×105 kg over life cycle.At the same time,the LCC of maglev chiller is lower than screw chiller under the same design scheme,and about 100 000～140 000 Yuan can be saved for each chiller.The cost advantage of maglev chiller over screw chiller begins to emerge after 8 years of use.The sensitivity analysis of electricity price indicates that it is more economical for maglev chiller when electricity price is higher than 0.7 Yuan/(kW·h).The results can provide theoretical support for the energy-saving effect and economic advantages of maglev chillers,and have important reference value and significance for the decision-making of related engineering projects.
