基于DPSSHP的分布式供能系统在赣南地区的研究

赣南地区城市污水排放量较大,工业废水富含大量余热。发展基于直接式原生污水源热泵(Direct Primary Sewage Source Heat Pump,简称DPSSHP)的分布式供能系统,向建筑供冷供热,将大大降低建筑空调采暖能耗。根据赣南地区实际情况,提出了DPSSHP系统针对不同类型建筑的应用规划。选取了地下水源热泵,大型螺杆式冷水机组+燃煤锅炉,风冷式空气源热泵、DPSSHP,从系统初投资、运行费用、单位面积运行成本等方面进行经济性比较,得出DPSSHP较为经济。

Distributed Energy Supply System of DPSSHP in South Jiangxi Area

There is a large amount of sewage discharge in South Jiangxi area, and the industrial wastewater is rich of heat. Developing the distributed energy supply system based on the direct primary sewage source heat pump technology is benefit to supply cooling or heating for buildings. And it will greatly reduce air conditioning and heating energy consumption in buildings. According to the actual situation of South Jiangxi area, the application plan of DPSSHP system is proposed aiming at different types of buildings. The underground water source heat pump, large screw water chiller adding to coal-fired boiler, the air-cooled air source heat pump, and DPSSHP are compared on the initial investment, operating expenses, operating costs per unit area, the cost of DPSSHP is good.
