Numerical and experimental study of a combined solar Chinese kang and solar air heating system based on Qinghai demonstration building

摘要

To meet the heating demand in north China and reduce the pollution of traditional Chinese kang, a novel combined heating system consists of solar kang system and solar air heating system is proposed. The solar air system is built for the residents' daily heating demand. The solar kang system can store the solar energy collected in the daytime and provide a good sleeping environment at night.
