该文在玻化微珠保温材料的基础上,依据相变原理,采用石蜡为相变基材,研发了玻化微珠相变新型无机保温蓄热材料。对辽沈Ⅰ型和采用玻化微珠相变保温材料的低能耗温室的室内温度进行了模型试验,并采用以稳定传热理论为基础的计算方法对辽沈Ⅰ型温室和低能耗温室的耗煤量、二氧化碳等的排放量以及采暖费进行了计算。研究结果表明:该文研制的新型玻化微珠相变保温材料的热物理性能可满足节能型日光温室的使用要求;将该材料应用于日光温室中,不仅可以减小墙体厚度,节约土地,还可在消耗较低能量的基础上,满足冬暖型温室大棚室内温度要求,达到节能和环保的预期目标。
On the basis of the vitrified microbead insulation materials, based on the phase change principle, paraffin is used as the phase change substrate, and a new type of inorganic thermal insulation material is developed. The indoor temperature of Liao-Shen type I and the low-energy greenhouse with glass bead micro-phase change thermal insulation material was tested and the calculation method based on the theory of steady heat transfer was used to simulate the Liao-Shen type Ⅰ greenhouse and low-energy greenhouse Coal consumption, carbon dioxide emissions and heating costs were calculated. The results show that the thermophysical properties of the new type of vitrified microsphere phase-change thermal insulation material can meet the requirements of energy-saving sunlight greenhouse. Using this material in solar greenhouse not only can reduce the thickness of the wall, save land , But also on the basis of lower energy consumption to meet the winter temperature greenhouse indoor temperature requirements to achieve the expected goal of energy saving and environmental protection.
