The Research And Selection On Transformation Plan For The Western Refrigeration Station Of Capital International Airport

With the expansion of Beijing capital international airporttraffic is constantly increasing,the refrigeration problems of densely populated public places is also becoming more prominent.The original refrigeration of west airport station was built in the 1990 s,and formally put into use on July 1 in 1999.The refrigeration station operates 9 units of steam lithium bromide absorption chillers.Vacuum system performances degradation,equipment has entered the phase of unstable operation,refrigeration effect was greatly affected.As the ice storage and water cool storage technology has become increasingly mature,this problem has been effectively alleviated.The technology is mainly by adjusting the peak trough of electricity consumption,put excess electricityat night to continue cooling,in the form of ice and water will be stored cooling capacity,and released when the daytime peak period,to ease the demand for electricity during the day.This article will mainly through the feasibility analysis of capital airport west refrigeration station renovation project of ice storage and water cool storage technology,get the conclusion of superiority.
