Thermal Performance Analysis of Different Solar Greenhouse Wall Structures
[Objective]To explore the insulation performance of different solar greenhouses in the Yangling area and identify a suitable energy-efficient greenhouse for promotion. [Method] Thermal performances of different solar greenhouse wall structures were compared: Traditional thermal storage (G1), phase-change stabilized earth (G2), cast-in-place concrete (G3), and modular thermal storage (G4). [Result] The findings demonstrate that, under typical sunny conditions, the average temperatures inside the four greenhouses are 15.68, 15.83, 16.52, and 18.44 ℃, respectively. Under typical overcast conditions, the respective average temperatures are 8.09, 11.12, 10.97, and 11.21 ℃. [Conclusion] The modular G4 greenhouse exhibits the capability to maintain elevated temperatures during winter nights, thereby providing a more favorable environment for winter crop cultivation. Moreover, due to its unique construction technique involving local resource utilization, the modular sunlight greenhouse offers advantages such as shortened construction duration, standardized development, and facilitation of mech-anized processes. Consequently, it holds promising prospects for widespread implementation in the Yangling and greater northwestern regions.
