不同墙体结构日光温室保温性能试验

Thermal Insulation Performance Test on Sunlight Greenhouse with Different Wall Structure

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 thermal insulation performance of sunlight greenhouse with different wall structure under continuous low temperature weather in winter,3 kinds of structures greenhouse that widely applied in Beijing area were selected to carry out thermal insulation performance test. They were lower concave structure of retaining wall,brick and polystyrene board structure,and brick and concrete structure. Results showed that thermal insulation performance of lower concave structure greenhouse was the best. Thermal insulation performance of brick and polystyrene board structure greenhouse was better than brick and concrete structure greenhouse. Thermal insulation performance of brick and concrete structure greenhouse was the worst. It had a good guiding significance for the prevention of low temperature disaster in sunlight greenhouse in winter.
