建筑节能已成为我国节能技术领域的重要议题。冷热电三联供技术是充分利用低品位热能的一种有效手段,该系统能源综合利用率高,一般均可达到70%以上。本文阐述了分布式区域冷热电联供系统的原理和特点,提出一种基于热气机的天然气能源岛系统。并指出充分推动分布式区域冷热电联供技术的应用,对于节约能源、环境保护、能源安全以及资本有效运作具有十分重要的意义。 Building energy efficiency has become an important issue in China's energy-saving technologies. CCH technology is an effective way to make full use of low-grade thermal energy. The comprehensive energy utilization rate of the system is high, generally up to 70%. This paper describes the principle and characteristics of the distributed district cogeneration system, and proposes a natural gas energy island system based on the steam turbine. And pointed out that it is very important for energy saving, environmental protection, energy security and effective capital operation to fully promote the application of CCHP technologies in distributed areas.
