Energy saving renovation practice of air conditioning cold and heat sources in an office building
The energy-saving renovation experience of air conditioning cold and heat sources in an office building has been introduced.It summarizes that in areas with hot summer and cold winter,under the premise of limited resource and site utilization,from the perspective of safety,stability,and energy-saving economy,low-grade air thermal energy and high-efficiency magnetic levitation chillers can be fully utilized to improve the heating and cooling efficiency.With the help of interlocking staggered starting,the problem of difficulty in increasing power capacity can be solved.Relying on the cold(hot)storage system can reduce energy consumption during peak electricity consumption,effectively achieve peak load shifting and valley filling of electricity.Compared to the original cold and heat source scheme,this system is safer,more efficient,andmore economical.
