Analysis of energy saving effect of green building exterior wall structure based on ANSYS simulation analysis

Abstract

For the accuracy of the results of this research, this article only studies some buildings in areas with extremely low temperatures. In extreme weather, these buildings require external wall structures with good thermal insulation to achieve the effect of cold protection. How to make the exterior wall structure of these buildings energy-saving and environmentally friendly is the key issue of our research, and it is also an urgent issue in architectural design. Although the exterior wall occupies a small area in the overall building, the exterior wall plays a major role in the design and thermal insulation of the entire building. Effectiveness, energy consumption and other aspects play an important role. In order to clarify the thickness of the cold-proof system of the concrete foam external wall, we used ANSYS to model the parameter model and predict the special situation, and compared with the original cold-proof material, to study the thermal insulation effect of the foam concrete cold-proof wall. We have obtained through experiments and calculations that when the thickness of the concrete foam is 145 mm, the cold protection effect of the concrete foam exterior wall cold protection technology is very similar to that of the 50 mm thick polystyrene board exterior wall cold protection system. We compared and analyzed the envelope structure of the existing buildings, and did a lot of experiments and tests to provide some information support and solutions for the changes of the envelope structure. After weighing the pros and cons, we chose the cold protection method of the envelope. After changing the structure of the building, after testing, we found that this method is effective in preventing cold and heat preservation, and the speed of cold current transmission is greatly slowed down, so there will be no freezing of the internal structure. And the concrete material can make the internal structure more stable, will not break due to the huge temperature difference between indoor and outdoor, and enhance the effect of heat preservation. This article focuses on the study of CPU automatically discharging heat during operation, and decomposes and observes the internal structure of the ANSYS system, observes how these systems perform heat rejection and cooling, and we also analyze the characteristics of the cold aisle open IDC system. Based on the research, we compared and analyzed two heat removal methods.
