The Structure Design and Thermal Insulation Performance of a New Type of Thermal Insulation in Solar Greenhouse
摘要
Abstract
Objective] The aim was to research and develop a new type of thermal insulation in solar greenhouse which is cost-effective and can replace traditional thermal insulation.[Method] Out of fabrics were chosen coated nonwoven, military base film, EPE composite black PE woven cloth, nonwoven fabric composite black PE woven cloth, inside fabrics were chosen nonwoven fabric; the core materials were chosen polyester wadding, miscellaneous wool, EPE, chemical fiber cotton, microporous foaming material.Through static test and outdoor test, with mainstream market thermal insulation(nylon oxford+chemical fiber cotton) and (coated nonwoven+chemical fiber cotton thermal insulation) as standard, the thermal insulation property was analyzed, and the tensile strength was tested.[ Result] Static test report showed that heat preservation rate of polyester wadding and miscellaneous wool thermal insulation was 84.0% and 83.3% respectively, that of coated chemical fiber cotton and nylon oxfordthermal insulation was 75.0%and 65.0%.The outdoor experiment showed that, when minimum temperature out-door was -24.4 ℃, heat preservation effect of polyester waddingthermal insulation was besst, temperature indoor was 5.4 ℃, average tem-perature outdoor was -9.3 ℃ and average temperature indoor weas 14.7 ℃;heat preservation effect of miscellaneous wool thermal insulation followed, when outdoor temperature was -24.4 and -9.3 ℃ , indoor temperature was up to 4.2 and 14.3 ℃; nylon oxfordchemical fiber cotton and coated nonwovenchemical fiber cotton thermal insulation had poorest Effect, when outdoor temperature was -24.4 ℃, indoor tem-perature was 2.8 and 3.6 ℃.[Conclusion] Polyester wadding and miscellaneous wool thermal insulation has good performance, which can be promoted as a new type of thermal insulation materials in solar greenhouse.关键词
