摘要：

To discuss the heating feasibility of solar energy-ground source heat pump system in inner Mongolian areas, based on the resource conditions of the Inner Mongolian areas, a large-scale building in Hohhot City is selected to conduct the TRNSYS simulation study during the heating season. Results show that within five years of the simulation operation, the COP average values under the heating mode and auxiliary mode are 3.87 and 4.83 respectively, both of which are in the COP averages of the heat pump system in the northern China between 3 to 5. After operation for five years, the soil temperature drops are 0.39℃, 0.31℃ respectively while the heating effect in auxiliary mode is better. Compared with coal-fired boilers and cogeneration heating, 53.98% and 34.82% of the energy consumption are saved in the auxiliary mode, indicating a significant energy-saving effect; The relative operation costs of the other heating modes such as coal-fired boilers, gas-fired boilers, oil burning boilers and cogeneration is 1.88, 1.42, 4.73, 13.13 and 1.00 respectively, while that of the solar-ground source heat pump system is slightly higher than coal-fired boilers and cogeneration, but far lower than gas boilers and oil-fired boilers. By using the fuzzy analysis method, the environmental optimization values of the above heating methods is 0.781, 0.292, 0.841, 0.531 and 0.347 respectively, and that of heating by the solar-ground source heat pump system is slightly lower than gas boilers, but far higher than other methods. © 2021, Solar Energy Periodical Office Co., Ltd.
