中文摘要	分析了贵州地区的气候特点,对贵阳市某大型公共建筑的冷、热、电及生活热水负荷进行了预测,针对发电并网不上网和发电上网两种情况,对燃气冷热电联供系统进行了优化配置和运行。两种方案均采用热泵型的冷热电联供系统,冬季在使排烟温度降至20℃左右的同时,回收部分浅层地热能,提高了系统的能源利用效率。以建筑原供能方案为比较基准,对两种方案进行了经济性和节能性评价。结果显示,两种方案的经济性相差不大;受贵州地区气候特点影响,建筑负荷匹配结构不利于冷热电联供系统的节能,如果发电可以上网,能使系统的节能性得到明显改善。; Analyses the climate characteristics of Guizhou area,and forecasts the heating,cooling,power and domestic hot water loads of a large public building in Guiyang.Optimizes the configurations and operations of two natural gas combined cooling,heating and power(CCHP)systems under two circumstances of grid-connection without power injection and with power injection.The heat pump type CCHP system is used in the two plans.In winter,the temperature of the flue gas can be reduced to about20 ℃,and the geothermal energy is extracted by the absorption heat pump at the same time,which increases the energy efficiency of the system.Compared with the original energy supply plan,the CCHP systems are evaluated on economy and energy efficiency.The results show that the economics of the two plans differ little.Because of the climate of Guizhou area,the matching configuration of the building loads is not good for energy saving of the CCHP system.But if the power generated by the unit can be injected into the grid,the energy efficiency can be improved significantly.
