摘要
应用增量投资法对天津市某楼宇的燃气热电冷联产系统进行了评价,用规划优化的方法建立了相应的数学模型,并进行了优化,分析了影响燃气热电冷联产系统经济性的重要因素,得出在实际应用中,要谨慎看待楼宇的燃气热电冷联产系统相对于热电冷分产系统的节能、经济优势。
A eogeneration system based on a natural-gas turbine with absorption chillers seems to be a very promising route to satisfy the needs for electrical, heating and cooling energy in a building or group of buildings. The increase quantity investment method was used in the building cogeneration system in Tianjin City to evaluate its economy under the natural-gas and electricity price and their increase quantity. The mathematics model was established correspondingly and optimized in the area. The important factors that influence system economy have been analyzed. The minimum recovery year was easy to be defined in this area. The data and mathematics model correspondingly were benefit to economy evaluation of the BCHP system.
