摘要:

在全球气候变化日益加剧的背景下,推行建筑节能减碳并实现零能耗建筑,已成为应对气候变化与资源枯竭的关键举措。变电站是城市化建设进程中不可或缺的重要建筑,目前严寒地区变电站普遍采用能耗较高的电采暖方式。鉴于此,依托建筑周边环境资源,对变电站现有冷热源系统开展优化,提出了切实可行的建筑节能减碳方案。通过计算流体动力学方法论证得出,过渡季与夏季采用自然通风能够实现运行负荷的动态平衡;太阳能光伏系统的年发电量可达18.75 MW·h;空气源热泵供暖相比电加热方式节能44.50%;而光伏-热泵复合供能系统相较于传统电供暖,每年的CO₂减排量高达4.90 t。研究结果验证了严寒地区变电站主控楼采用光伏发电+热泵供能技术模式的工程可行性。

Abstract:

In the context of intensifying global climate change, promoting building energy conservation and carbon reduction and achieving zero-energy buildings have become critical measures to address climate change and resource depletion. Substations are indispensable structures in the process of urbanization. Currently, heating systems in substations located in severely cold regions typically rely on energy-intensive electric heating. Therefore, the existing cold and heat source systems were optimized by leveraging the surrounding environmental resources, and feasible schemes for building energy conservation and carbon reduction were proposed. During the research process, CFD methods were employed to demonstrate that the adoption of natural ventilation in the transitional season and summer could achieve a dynamic balance of operating loads. The annual power generation of the solar photovoltaic system could reach 18.75 MW·h. Air source heat pump heating saved 44.50% energy compared to electric heating. Furthermore, the photovoltaic-heat pump hybrid energy supply system achieved an annual CO2 emission reduction of up to 4.90 t compared to traditional electric heating. The findings validate the engineering feasibility of the photovoltaic power generation and heat pump energy supply technology model for main control buildings of substations in severely cold regions.
