Research And Development For Windows And Doors Curtain Wall Thermal Performance Comprehensive Calculation System

With the rapid development of Windows and doors curtain wall industry and the change of people’s attitude to architecture aesthetics, windows and doors curtain wall product has been widely used in our country.Designing a windows and doors curtain-wall product which has a good thermal performance and Achieves a energy-saving building is the development trend of the industry. At the same time, In present design analysis of the current windows and doors curtain wall, high individuality demand, low design efficiency, frequent changes in the specifications, high error rate, great waste of raw materials, large repeated workload, etc., are ubiquitous, Therefore, this article embarks from the research of Windows and doors curtain-wall thermal performance, around real requirement of comprehensive calculation for Windows and doors curtain wall thermal performance, makes a deep study of the calculating system of Windows and doors curtain wall thermal performance and its core technologies, and Windows and doors curtain wall thermal performance comprehensive calculation system is developed.First of all, based on the analysis of Windows and doors curtain wall thermal performance computing technology and its system design research status at home and abroad, this article proposes a application logic layer as the core of the three layer structure of Windows and doors curtain wall thermal performance comprehensive calculation system overall scheme.Secondly, this article studies the core technologies involved in thermal calculation and automatic generation of calculation result list. Aiming at the characteristic of System upgrade and frequent changes in the specifications. A thermal calculation method based on the standard template and the expression driven algorithm was proposed,the method stored the thermal calculation formula and the Calculation rules in the standard template, entered the relevant parameters and boundary conditions,and obtained corresponding data from related parameters database automatically,Then called the corresponding calculation formula in the standard template to get related thermodynamic performance parameters Through the expression driven technology. Aiming at the problem of large workload and high error in generating computing result list by hand,this article defined a set of output identification about calculation result list,and proposed a method about automatic generation of calculation result list based on output identification, the method used the data table store all calculation content, according to the output identification, calculation module records were configurated and instantiated, generating temporary document which contained document translation information, At last, relevant documents,forms and pictures were inserted and document format was set according to the format identification.Finally,based on above studies, the windows and doors curtain-wall thermal performance comprehensive calculation system is developed. The system is characterized by strong practicability, simple operation and good interaction,can Provide support for Windows and doors curtain-wall system performance analysis.
