摘要
为了提升太阳能和热泵技术的节能减排效果,研究设计了结合太阳能技术和热泵技术的供暖系统.在建筑热负荷计算的基础上对供暖系统进行了构建,并对该供暖系统的运行模式进行了分析.为了对供暖系统的节能和减排效果进行分析,搭建了TRNSYS仿真平台,并对该仿真平台的准确性进行了验证.实验结果显示,所设计供暖系统的标煤节约量为4 189.7 kg,一次能源节约率为 65.78%,系统能效比为 3.15,CO2、SO2 和粉尘的减排量分别为 10 608.8、82.6、82.7 kg.所设计的供暖系统具有良好的节能减排效果.
Abstract
In order to improve the energy conservation and emission reduction effects of solar energy and heat pump technology,a heating system combining solar energy technology and heat pump technology was studied and designed.Based on the calculation of building heat load,the heating system was constructed and the operating mode of the heating system was analyzed.In order to analyze the energy conservation and emission reduction effects of the heating system,a TRNSYS simulation platform was established and its accuracy was verified.The experimental results show that the standard coal savings of the designed heating system are 4 189.7 kg,the primary energy savings rate is 65.78%,the system coefficient of performance is 3.15,and the emission reductions of CO2,SO2 and dust are 10 608.8,82.6,82.7 kg,respectively.The heating system designed has good energy conservation and emission reduction effects.
