某高校天然气分布式能源站及供能管网系统

上海某新建高校采用天然气分布式能源系统通过供能管网实现区域供能。能源中心以天然气作为一次能源,采用冷热电三联供技术,并辅以电制冷机组和燃气热水锅炉作为调峰设备,可满足该新建校区所有冷热负荷需求,能源综合利用效率达到80%以上。能源中心通过校区各二级泵房向各空调末端直接提供循环冷热水,通过校区各热交换机房提供生活热水一次侧热媒。空调供能管网及生活热水热媒管网均采用两管制闭式循环系统。目前该能源中心及供能系统已成功运行。

The Natural Gas Distributed Energy Station and Energy Supply Pipe Networks in an University

District energy supplied by pipe networks from natural gas distributed energy system is established in a new university in Shanghai.Natural gas is used as primary energy in this energy station.And all cooling and heating requirements of this university are satisfied by CCHP (Combined Cooling Heating and Power) technology and peak-shaving equipments (electric refrigerating units and gas-fired hot water boilers) used in it.Its energy comprehensive utilization efficiency reached more than 80%.Circulating cold and hot water for air-conditioned terminals is directly provided by every second pumping stations from the energy station, and one-side hot medium for domestic hot water is provided in every heat exchange rooms from the energy station.The pipe networks of energy supply for air conditioning is two-pipe style closed circulating system, as same as the networks of heat medium for domestic hot water.This energy supply system is running successfully now.
