摘　　要：随着光储直柔建筑配电系统的提出,直流家电成为光储直柔建筑推广应用中的一个技术瓶颈。在典型的家庭场景中,大多数电器内部都以直流电的形式消耗电能。对家用空调器进行了内部组成变化的理论分析,并对220 V交流供电和400 V直流供电的家用空调器开展能效以及经济性比较研究。研究发现,直流家用空调器在能效及经济性方面较交流电器均存在优势。DC appliances have become a technical bottleneck in the promotion and application of optical storage direct-soft building due to the proposed distribution system of optical storage direct-soft building.In a typical household scenario,most of the appliances consume power internally in the form of DC.In this paper,a theoretical analysis of the change in internal composition of domestic air conditioners is carried out,and a comparative study of 220 V AC-powered and 400 V DC-powered domestic air conditioners is conducted in terms of energy efficiency and economy.It is found that DC domestic air conditioners have advantages over AC appliances in terms of energy efficiency and economy.
