小型公共建筑供能方式技术经济性比较

Techno-economic Comparison among Energy Supply Modes for Small Public Buildings

小型公共建筑(建筑面积在3×10~4m^2以下)可采取的供能方式包括:燃气热水锅炉联合电制冷机组、直燃型溴化锂吸收式热泵机组、地埋管地源热泵、燃气冷热电三联供系统。以某工程为例,从工程造价、能耗费用、能源站占地等方面对4种供能方式进行技术经济性比较,探讨小型公共建筑适宜的供能方式。

The energy supply modes that can be used in small public buildings with floor area of less than 3×10^4m^2 include gas hot water boiler combined with electric refrigeration unit, gas direct-fired lithium bromide absorption chiller unit, ground source heat pump, gas-fired combined cooling, heating and power. Taking a project for example, the techno-economic comparison among four kinds of energy supply modes are performed in terms of project cost, energy consumption cost, floor space of energy station and so on, and the appropriate modes of energy supply for small public buildings are discussed.
