摘要
采用了TRNSYS仿真模拟的方法,详细地研究了多种热源组成的联合供热系统的最经济节能的能源配比方式。设置了五种能源配比形式,计算了每个方案分别在20年,30年,40年的合理运行期限下的平均年运行费用。最后得出结论,当波峰电价为0.585 8元/k Wh,波谷电价为0.326 3元/k Wh时,合理运行期限为20年,30年,40年的情况下,方案四都能达到最优的经济性。
In this paper, TRNSYS sinmlation method is used to study the most economical and energy-saving energy allocation of the combined heating system composed of solar energy, water source heat pump, electric heating and heating nelwork. Five lypes of energy ratios are set up in this paper, and the average annual operating costs of each scheme are calculated under 20, 30 and 40 years of reasonable operating time respec- tively. Finally, it is concluded that when the peak price is 0. 585 8 yuan/kWh, the trough price is 0. 326 3 yuan/kWh, and the reasonable oper- ation period is 20, 30, 40 years, the optimal economy can be achieved in scheme 4.
