In order to improve the efficiency of electrical engineering, it is necessary to strengthen the application of energy-saving design technology in the application process of electrical engineering. In recent years, new technologies have been applied to the research of electrical automation in China, and some breakthroughs have been made. In fact, the application of electrical automation technology is a relatively long process, but if the energy-saving design of electrical automation can be realized, the consumption of some non-renewable resources in China can be gradually reduced, and it also plays a very important role in environmental protection. In addition to the electrical automation related energy-saving design, but also to constantly improve some problems in the traditional energy-saving design, and put forward new energy-saving scheme, in order to help China's environmental protection work smoothly. This paper studies and analyzes the application of energy saving design in electrical automation for reference.展开更多

In todays society, environmental problems are becoming more and more serious, especially the pollution problems caused by building construction. In order to reduce the adverse impact of building pollution on the ecological environment, energy conservation and emission reduction design is becoming more and more widely used in construction engineering construction. HVAC system is the main source of building energy consumption in China. Therefore, the construction unit should keep pace with the times, strengthen the relevant design of energy conservation and emission reduction, timely grasp the development trend, and formulate scientific development plans. At the same time, the designers should constantly improve their overall quality, and make their own contributions to the development of the construction industry. This paper starts with the energy saving and emission reduction design of building HVAC project and analyzes it.展开更多
