In this study, the economic and environmental performance of four active solar heat storage-release (AHS) systems compared with four other conventional heating systems (as practical options in northern China) were investigated in an experimental test of their ability to store energy during the daytime and heat a Chinese solar greenhouse (CSG) at night during the cold winter in northern China. The case-4 AHS performed best in terms of economic performance compared with the other three designs and four other conventional heating systems. However, future investigations of the long-term performance and environmental impact of AHS heating in greenhouses are needed and further improvements must be developed.
