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