摘要
利用DOE-2软件对寒冷地区宾馆用户全年逐时热、电、冷负荷进行模拟,并用四相位图分析了联产系统全工况下的运行模式.对寒冷地区宾馆热电冷联产系统进行方案及运行模式的优化,以净现值为评价指标,在"以热定电"运行方式下,微型燃气轮机+热水型余热锅炉+单效吸收式制冷机的组合方案最优,净现值为1 563万元人民币;以净现值率为评价指标,在"以热定电"运行方式下,燃气内燃机+热水型余热锅炉+单效吸收式制冷机的组合方案最优,净现值率为2.08.
Each hour thermal,power,cool load of hotel user in cold area are simulated by DOE-2 software,the cogeneration system＇s operation mode in all conditions is analyzed by four-phase bitmap.The optimization of hotel thermal,power,cool cogeneration system plan and operation mode in cold area,taking the net present value as the evaluation index,under the operation mode ＂thermal deciding power＂,the plan ＂micro gas turbine＋hot water type waste heat boiler＋single-effect absorption-refrigerator ＂is the optima,the net present value is 0.85.
