摘要/Abstract

摘要： 【目的】研究日光温室冬季补温热负荷以及相应加温设备配套功率选型的准确性,计算日光温室冬季能耗的热损失,研究温室专用热风炉补温设备与理论计算能耗一致性问题。【方法】分析温室的总体热损失,研究各个围护结构的热工性能,取值计算温室总热损失量,分别计算出温室围护结构热损失、冷风渗透热损失以及温室内地面热损失占温室总散失热量的比例。【结果】温室理论计算单位面积能耗为166 W/(m²·h);单位面积能耗为142 W/(m²·h),二者基本趋于一致。【结论】各个围护结构的热工值取值合理,温室加温设备配套功率选型较为准确。温室加温热负荷计算时,不应考虑白天温室获得的太阳辐射热量,应将温室夜间最低温度时刻和极端灾害气候下温室需要补充满足的热量作为温室的加温热负荷值。

Abstract: 【Objective】 In order to study the heat load of solar greenhouse in winter and the accuracy of power selection of corresponding heating equipment, the heat loss of energy consumption in winter in solar greenhouse is calculated and the special hot blast furnace equipment for greenhouse is designed. Meanwhile, the consistency between energy consumption and theoretical calculation of energy consumption is studied. 【Methods】 The total heat loss of greenhouse was analyzed, the thermal performance of each enclosure structure was studied, the reasonable value was calculated to ensure the accuracy of the calculation of the total heat loss of greenhouse, and the three parts of energy consumption loss of greenhouse enclosure structure, cold air permeation heat loss and greenhouse surface heat loss were calculated respectively. 【Results】 The experimental results showed that the theoretical energy consumption per unit area of greenhouse is 166 W/m². During the test, the energy consumption per unit area was 142 W/(m²·h). 【Conclusion】 Through experimental analysis, the thermal value of each enclosure structure is reasonable when calculating energy consumption in greenhouse theory, and the power selection of greenhouse heating equipment is relatively accurate. In the calculation of greenhouse heating load, the solar radiation heat obtained by the greenhouse during the day should not be taken into account. Instead, the heat that the greenhouse needs to be supplemented and satisfied under the climate of extreme disasters should be taken as the heating heat load value of the greenhouse.

Key words: solar greenhouse; heat load; hot blast furnace; supplementary heating; heat loss
