寒冷地区变电站主控楼冷热源系统设计与节能优化OA

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.
