Abstract

Abstract: 【Objective】 To build solar greenhouses with low energy consumption, thus improving the passive utilization rate of solar energy from off-season vegetable production and other plants production in the key growth period and reducing the demand for heating in greenhouses.【Method】Based on the theory of building thermal design and building simulation analysis method, this project studied the influence of building space shape characteristic parameters on greenhouse light and heat environment construction. Combined with the architectural characteristics of solar greenhouse, and the characteristics of off-season vegetable crop production process of light and thermal environment requirement characteristics, the design conditions of spatial morphological parameters of solar greenhouse with low energy consumption were given.【Result】The results showed that the the height span ratio of solar greenhouse in the same area was affected by the change of span, only associated with changes in local outdoor air temperature and solar radiation intensity. During Dashu to Xiaoman of the next year, the horizontal projection length of the rear roof did not affect the solar illumination of the vegetable crops in rear rows in the solar greenhouses. To ensure that the northern wall receive solar light during the Winter Solstice's day to Greater Cold's day had an important influence on the solar energy utilization in solar greenhouse during the off-season vegetable crop production period in winter.【Conclusion】Based on this design principle, the accumulative heat load of optimal design greenhouse is less 15.7% than the existing greenhouse in Beijing. The research results can provide important design basis and method reference for the optimization design key parameters of low energy consumption solar greenhouse morphology.

摘要： 【目的】建造低能耗日光温室,提高日光温室冬季反季节蔬菜作物生产太阳能被动利用率、降低温室供热需求。【方法】基于建筑热工设计理论和建筑能耗模拟,研究日光温室建筑空间形态特征参数对温室光热环境营造的影响规律,并结合日光温室建筑构造特点,以及反季节蔬菜作物生产过程的光热环境需求特点,给出低能耗日光温室建筑空间形态特征参数的设计条件。【结果】同一地区日光温室高跨比不受跨度变化的影响,只与当地室外空气温度以及太阳辐射强度的变化相关;大暑日至翌年小满日期间,后屋面水平投影长度不应影响日光温室后排蔬菜作物接收太阳光照;确保冬至日至大寒日期间北墙可接收太阳光照射,对冬季反季节蔬菜作物生产期及日光温室高效利用太阳能具有重要的影响。【结论】基于该取值原则优化设计的温室,较北京地区现行常见温室需要提供的累积补充供热量减少15.7%,节能效果明显,为低能耗日光温室优化设计提供重要设计依据和方法参考。
