Economical Analysis of Ice-storage Air-conditioning Technology Applied in One Project in Beijing

摘要

Ice-storage air-conditioning system is a new technology to balance the electricity supply,which will relieve the shortage of energy supply,and reduce the investment and running cost of air-conditioning system.This system has seen a vast outlook in application.However,the effects of economy and optimization of ice storage air-conditioning system are very complex,so it has not been used widely.Therefore,the study on economical analysis and optimization of ice storage air-conditioning system was conducted.In the first step of the study,the cooling load was calculated by DeST,the charged rate was got according to the cooling load on July 25th,and the equipment was chosen based on the calculating results.In the second step,the study on economical analysis and optimization of ice storage air-conditioning system was analyzed by Mat lab and Lingo.Finally,a project in Beijing was analyzed and the running cost of air-conditioning season was gained.By comparing the results between the ice-storage system and the general one,a great amount of running cost was saved in ice-storage system in Beijing area.
