为了评价在冬季持续低温天气下不同墙体结构日光温室的保温性能,选取北京地区推广应用广泛的土墙下凹结构、砖加聚苯板结构和砖加混凝土结构的日光温室进行了保温性能试验。结果表明,土墙下凹式温室在持续低温天气条件下保温性能最佳,砖加聚苯板温室的保温性能明显好于砖加混凝土温室,砖加混凝土温室保温性能最差,该结果对防御日光温室冬季低温灾害影响有较好的指导意义。
In order to evaluate the thermal insulation performance of solar greenhouse with different wall structures in low temperature in winter, the thermal insulation performance of solar greenhouse with brick wall and concrete structure plus brick, . The results show that the thermal insulation performance of the soil wall concave greenhouse is the best in the continuous low temperature weather conditions. The thermal insulation performance of the brick plus polystyrene board greenhouse is obviously better than that of the brick-concrete greenhouses, and the brick-concrete plus greenhouse has the worst thermal insulation performance. Winter greenhouse low temperature disasters in winter have a good guiding significance.
