Construction practice of market system for energy saving renovation of existing buildings

The energy-saving reconstruction market of existing buildings is a complex system.It includes three subsystems:service market,capital market and technology market.The service market takes the relationship between energy service companies and owners as the core to establish service associated relationships.The capital market is based on the mechanism of"investment guarantees and risk sharing"to form structures of the capital market.The technology market relies on the"industry-university-research"mode to build technology supporting platforms.Being interdependent and mutually restricted,the three subsystems form the complete system of existing buildings in energy-saving reconstruction.

溶液调湿空调在医药厂房工程应用的碳减排潜力分析

众多医药生产车间要求低湿环境,需要送风含湿在7 g/kg甚至5 g/kg以下,常规7℃冷冻水驱动的冷冻除湿方式难以完成上述除湿任务,因而医药厂房通常采用转轮除湿系统对空气进行湿处理以满足环境热湿控制需求。然而,转轮系统所需再生温度较高,通常使用高温蒸汽或电加热器作为再生热源,限制了系统的低碳化运行。溶液空调系统具有利用低品位冷热源的优势,但现有研究对于溶液空调技术在医药建筑中应用可行性研究尚不充分,无法揭示其在医药建筑应用的节能减排潜力。因此,现场测试了溶液空调系统在某试点医药厂房的实际应用效果,对比了其与常规转轮系统的性能差异并阐明差异原因。示范工程应用结果表明,一次回风系统送风含湿量在6 g/kg左右时,溶液系统可以将再生热源温度从100℃以上降至50℃以下,相较于常规转轮系统的节能比率为15%~45%,典型工况下的碳减排率为20.7%。以期为医药建筑低碳化发展提供经验参考与数据支撑。
