Suitability and Construction of Self-Insulation Walls in the Hot Summer and Cold Winter Zone of Southern Shaanxi

摘要

In this paper,the suitability and construction technology of self-insulation walls were studied under the specific climatic conditions and regional resources of Hanzhong and Ankang in the hot summer and cold winter zone of Southern Shaanxi.Through the calculation of heat transfer coefficient and thermal inertia index,combined with the specifications of the shale hollow brick and aerated concrete block of Hanzhong and Ankang in southern Shaanxi,the thermal performance and suitable thickness of the external wall using self-insulation materials that meet the Design Standard for Energy Efficiency of Residential Buildings(DBJ61-65-2011)in Shaanxi Province were obtained.The results showed that the self-insulation wall had technical suitability in the hot summer and cold winter zone.The research results provide not only a theoretical basis for the external wall insulation design of urban residential buildings in the hot summer and cold winter zone of southern Shaanxi,but also a reference for designers to carry out energy-saving design of external walls of residential buildings in other similar climate zones.
