提出太阳能-地源热泵与热网互补供热系统形式,选取严寒地区典型建筑为基准建筑,以T RNSYS瞬时模拟软件为平台,建立太阳能补热系统的仿真模型,从能耗、经济性两方面确定互补供热系统中各部分能源的最佳配比,经过研究得出系统在多种运行模式下的能源应用效率和节能状态。现阶段,我国供暖地区主要采用以燃煤为主的常规能源,由于供暖面积增大,已有热网无法满足小区供暖需求现象普遍存在,而这些地区太阳能资源非常丰富,利用太阳能满足供暖需求前景巨大。
The form of solar-ground source heat pump and heat network complementary heating system is proposed. The typical building in severe cold area is taken as reference construction. The simulation model of solar heat recovery system is established by using T RNSYS instantaneous simulation software. From the aspects of energy consumption and economy Determine the optimal proportion of each part of the energy in the complementary heating system, after researching the energy efficiency and energy saving status of the system under various operating modes. At this stage, China’s heating area mainly uses conventional coal-based energy. Due to the increase of heating area, existing heating networks can not meet the demand of district heating, and the solar energy resources in these areas are very rich. The utilization of solar energy to meet the demand of heating demand huge.
