Abstract

A demonstrative solar greenhouse with underground pebble bed thermal storage was established and compared with a control case greenhouse. According to the experimental results, the thermal storage power of the pebbled bed system is more than that of the buried pipe system, with values, 94 W/m² and 76 W/m², respectively. The lowest night temperature of the solar greenhouse with thermal storage is 5~8°C, which is higher than that of the greenhouse without thermal storage. And the temperature difference of day and night in the solar greenhouse is decreased, which is benefit for the thermophilic crops to live in the winter.
