摘要(Abstract):

以沈阳地区典型民用住宅建筑为例,对太阳能-地源热泵与热网互补供暖系统进行仿真研究。利用TRNSYS软件,建立太阳能-地源热泵与热网互补供暖系统仿真模型和地源热泵与热网互补供暖系统仿真模型,对2种系统的蒸发器进出水温度、热泵机组COP,及热网加热量进行对比分析,结果表明:太阳能-地源热泵与热网互补供暖系统相比地源热泵与热网互补供暖系统的平均出水温度提高了50.41%;平均进水温度提高了53.08%;平均COP由3.167增加到4.65;热网运行时间由1540h增加到2032h;热网供暖季的平均换热量由114566.62kJ/h减少到101257.27kJ/h。
Taking the typical building in severe cold region as an example,the simulation of solar-ground source heat pump and heating network complementary heating system was studied. By using TRNSYS software,build a solar-ground source heat pump and heating network complementary heating system simulation model and ground source heat pump and heating network complementary heating system simulation model,then make the contrast analysis of the in and out of the water temperature of evaporator,the COP of heat pump units,and the heating capacity of heat supply network in the two systems. The results show that compare ground source heat pump and heating network complementary heating system with solar-ground source heat pump and heating network complementary heating system,the average inlet water temperature increased by 50. 41%,the average outlet water temperature increased by 53. 08%; the average COP increased from 3. 167 to 3. 167; heat supply network running time increased from 1540 h to 2032 h,the average heat transfer of heat supply network heating season from 114566. 62 kJ /h is reduced to101257. 27 kJ /h.
