Analysis of the thermal performance of the novel assembled Chinese solar greenhouse with a modular soil wall in winter of Yinchuan, China

In order to improve the thermal insulation and storage performance of Chinese solar greenhouses in winter, a novel assembled greenhouse (ACSG) without energy supplement cold climatic areas was designed evaluate compare its with that conventional (CSG). The properties both were tested field on winter days Ningxia, China. results indicated land utilization rate ACSG 19.3% higher than CSG. On typical sunny day (the lowest outdoor temperature −22.0°C) cloudy −19.7°C) during experiment, minimum indoor respectively 1.7°C 2.0°C for 24 consecutive average daily air −19.0°C) showed 1.4°C CSG (p<0.05). modular soil wall attached colored steel polystyrene boards would be exploited as north Yinchuan area.
