调整能源结构、提高用能效率是国内外缓解能源危机的重要研究方向,本文针对分布式能源系统与地源热泵系统各自的优缺点,基于化学能、物理能梯级利用原理与因地制宜基本原则,提出分布式能源系统和地源热泵多能源耦合系统集成新方法,并以一案例系统(天然气燃机耦合地源热泵系统)进行分析。计算结果表明,多能源耦合供能系统不仅可以进一步提高能源利用效率,而且可为化石能源与可再生能源优势互补的能源利用技术提供新的发展思路,具有重大的现实意义。

Adjusting the energy structure and improving energy utilization efficiency have been an important research direction to alleviate the energy crisis at home and abroad. For the respective advantages and disadvantages of distributed energy system and ground source heat pump system, the new integration method of multi-energy system on distributed energy system and ground source heat pump system is proposed in paper based on the chemical and physics energy cascade utilization principle and adjusting measures to local conditions. And a case system is analyzed. The results demonstrate that the multi-energy coupling supply system can not only further improve energy utilization efficiency, but also provide a new development guideline for energy utilization technology of complementary advantages of fossil energy and renewable energy, which has great significance and realistic value.
