Research On The Application Of Phase Change Building Materials In Architectural Energy-saving

Building materials used to build phase change building envelope can reduce the indoor temperature fluctuations, increased comfort, the building heating or air conditioning to use less or use less energy, improve energy efficiency; can solve the thermal mismatch of supply and demand contradictions, the air conditioning or heating system uses low-cost electricity at night to run, reduce air conditioning or heating system running costs.The first is to ask questions of this thesis, research is now building energy-saving technology is mainly thermal insulation technology, which is mainly exterior insulation, wall insulation and then to understand the current technical shortcomings, leads to a new energy-saving ideas, using phase change materials, so building envelope, energy storage, to achieve energy-saving requirements.Then analyze the problem - that of building materials in the construction phase feasibility of the application. Discussed mainly from three o'clock:First, phase transitions do understand the technology of building materials and elaboration of its concepts, principles, selection, species characteristics, energy value, laying the groundwork for the subsequent application.The second is to discuss three aspects of the feasibility of its application, namely, preparation techniques, energy saving, application quality. Mainly through domestic and international research in the field, market products, laboratory testing, technical standards for building energy efficiency, energy-saving evaluation index, the domestic product quality testing methods, test parameters, construction, etc., elaborate on the technical advantages and discussions.Third, examples of the technology demonstration building at home and abroad, that phase change building materials on the floor, walls and other structural applications to maintain the energy saving effect.Finally, the article cites three residential use cases at home and abroad to explain the technical points of construction materials, construction of a large sample drawn map. And energy saving effect of the project made a preliminary analysis.The thesis concludes that the phase change in the application of building materials in the building energy-saving advantage, and with the application feasibility of the current application of such materials in China is, cold regions, summer and cold winter areas use cases, and in these areas recognized by the application of detection, but in the subtropical region does not find use cases in Guangdong is still not achieved the detection of authorities approved applications difficult. I believe that the application of phase change building materials is a very good prospect, but the promotion process, the need to be resolved are: variety of materials to be diversified further optimize performance, durability of materials and economic issues to be resolved, the pilot construction engineering test data to improve industry standards system and evaluation system to be established and so on.
