东北地区日光温室保温性能实验研究

EXPERIMENTAL RESEARCH ON HEAT PRESEVATION EFFECT OF NORTHEAST HELIOGREENHOUSE

本文通过对不同天气条件下我国东北地区日光温室各围护结构保温性能的实验研究,得出各结构表面温度与室内外温度关系,以及表面蓄热放热变化规律。实验结果表明:冬季夜间土壤为日光温室主要热源,提高墙体的蓄热隔热性能是改善温室热环境的重要方面。本研究为今后完善温室的优化设计提供理论依据。

The temperature and the heat flux characteristic were carried out by researching on heat preservation of northeast heliogreenhouse structures in different condition. The experiment research shows the soil is the primary heat source of heligreenhouse in winter night and it＇s an important aspect of enhancing the regeneration heat insulation performance of the wall in improving the hot environment of the greenhouse. This research will provide the theory basis for consummating heliogreenhouse optimized design in the future.
