地源热泵耦合消防水池系统的经济性分析

Economic analysis of ground source heat pump coupled with fire water pool system

为响应国家节能减排政策,降低工业用电成本,缓解高峰时段电网供电压力,以郑州某工程为例,采用地源热泵耦合消防水池系统为建筑供暖供冷,根据峰谷电价政策优化运行模式计算可知,较无消防水池的地源热泵系统,此方案每年运行成本可降低30%~40%,较传统的燃气锅炉+冷水机组供暖供冷系统,成本降低60%~70%。该方案可有效削减工厂电力开支,减轻用电高峰电网供电压力,同时降低碳排放量。

In order to actively respond to the call of the national policy of energy conservation and emission reduction,to reduce the cost of industrial electricity consumption,and to ease the power supply pressure of the power grid during peak hours,taking a cer-tain project in Zhengzhou as an example,a ground-source heat pump coupled with a fire-fighting water tank system is used to heat and cool buildings.According to the peak-valley electricity price policy,the operation mode is optimized.The results show that compared with the ground-source heat pump system without a fire-fighting water tank,the annual operation cost can be reduced by 30%to 40%,and compared with the traditional gas boiler+chiller heating and air conditioning system,the annual operation cost can be reduced by 60%to 70%.This solution can effectively reduce the power expenditure of the factory,ease the power supply pressure of the power grid during peak hours,and at the same time achieve a reduction in carbon emissions.
