摘要
以寒冷地区宾馆建筑为研究对象,利用Energy Plus软件,模拟建筑物全年逐时冷热电负荷。采用HUD CHP Screening Tool软件,对天然气冷热电联供系统(燃气内燃机发电机组+溴化锂吸收式制冷机组+余热补燃型锅炉+电制冷机组)设备配置与运行策略进行优化。以分供系统(市网电+燃气锅炉+电制冷机组)作为比较对象,联供系统的月均一次能源节约率、月均运行费用节约率分别为8.1%、23.1%。
Taking hotel building in cold region as research object, the all-year hourly cooling, heating and power loads of the building is simulated by Energy- Plus software. The equipment configuration and opera- tion strategy of natural gas combined cooling, heating and power system （gas engine generator set plus lithi- um-bromide absorption-type refrigerating unit plus ex- haust heat afterburning boiler plus electric refrigerating unit） are optimized by HUD CHP Screening Tool soft- ware. Compared with the non-combined cooling, heat- ing and power system （municipal power system plus gas-fired boiler plus electric refrigerating unit ）, the monthly average saving rates of primary energy and op- eration cost of the combined cooling, heating and pow- er system are 8.1% and 23.1% respectively.
