Energy Saving Technology

Energy-saving service industry becomes a new force suddenly rises, and will be the largest energy-saving industry in the world. Tangshan City, adjacent to Beijing and Tianjin, is a typical resource-based city. Because its industrial structure is based on iron and steel, petrochemical and other resources, while energy-consuming structure based mainly on coal, that made Tangshan become one of China's high energy-consuming cities. In 2011 the city's total energy consumption was 95.5282 million tons of standard coal, accounting for 32.4% of Hebei province's energy consumption, and 2.7% of the whole state's respectively, while Tangshan City's GDP accounting for 22.5% of Hebei province and 1.2% of the nation.The huge energy consumption promotes vigorous development of energy-saving industry.The scale of Tangshan's energy service industry increases rapidly currently, for example, the output value of energy service industry in 2009 reached 32 billion RMB, and then its scale is continues to expand, and EPC(Energy Performance Contracting) is implemented gradually. However, it also shows a lot of problems, such as samll amount of energy-saving enterprises, lack of core competitive companies, shortage of funds, financing difficulties, lack of leading enterprises, irrational personnel structure, and the market system has not formed yet. If Tangshan's energy-saving services industry wants to achieve a good development, it must concentrate on that the publicity of industrial policy, creating a favorable environment for its development, speeding up development and applications of energy-saving technology, establishing industrial norms, strengthening self-discipline, innovating financial system, improve the financing environment, establishing credit publicity system, and promoting construction of industrial credit system.

As a traditional high energy-consuming industry, the forging industry consumes a lot of energy. The activity consuming the highest energy during forging process is the heating. The problem regarding how to separate workpieces with the same holding temperature and holding time and combine them for charging in forging was analyzed and a model based on batch weight fit rule for optimizing the charging combination with the goal of energy saving was proposed. A genetic algorithm was adopted to optimize and solve the model in order to reduce energy consumption in forging. In addition, an instance was given to prove the effectiveness of the proposed model.

In the contemporary milieu of today, sustainability and environmental concerns have become a great subject of debate. Matters related to sustainability are often linked to other crucial concerns like energy consumption. Energy is a key factor in ensuring continuous economic growth and development. One of the highest energy consuming systems in buildings – specifically residential homes in tropical regions – is the air conditioning system. Windows have been identified as the weakest link in the fabric of a building as they serve as thermal holes. Thus, the selection of proper window materials is crucial to reduce energy usage by minimizing the cooling and heating requirements of the building. The aims of this paper are analysis of energy performance for diverse types of window’s glazing with different frames in order to find the most optimized window materials for the tropical residential buildings. The selected case study in this paper is modeled and then simulated by Building Information Modeling (BIM) application, which is appropriate for energy analysis. For simulation, some factors of the window materials were taken into consideration including, four physical properties of the U-factor, solar heat gain coefficient, visible transmittance, and emissivity. The result was shown windows types 02 and 03 were the most optimized of window materials and led to 10% energy saving into the base model and the windows type 05 was high U-factor, results in a greater transfer in internal zones and led to high energy consumption.

The topic is relevant due to the need to improve basic measurements of tractors, considering a major contribution they make to crop production, not only during separate technological operations, but also during a whole sequence of technological operations performed. The paper analyzes the limits to which the basic measurements of tractors (weight and engine power), which are used to perform a combination of technological operations requiring different energy consumption, can be altered and to identify practical limits to perform a combination of low and high energy-consuming activities. The key research method used is mathematical modeling based on system analysis and computational experiments that are carried out using models of implements during various technological operations. The results of calculations analyzed for technological operations that differ in the amount of energy consumed suggest that for each of the groups of technological operations that require similar amount of energy (soil resistivity per meter of working width, kN/m), there are fairly stable values of the basic measurements of tractors. A reasonable weight for tractors to perform operations such as harrowing, continuous cultivation of soil with a resistivity of 1 to 4 kN/m is 35-60 kN. For soil preparation with a resistivity of 4 to 8 kN/m it is 100-120 kN, for plowing with a resistivity from 10 to 16.25 kN/m – equal to 160 kN, for tillage with subsoilers with a resistivity from 8 to 16 kN/m – equal to 240 kN. Once put to practice, the findings will lead to a decrease in total energy consumption to 10,000 MJ/ha. The amount of saved energy costs depends on the type of technological operation, the parameters of tractors used, the characteristics of agricultural implements, soil properties, etc.

Healthcare facilities in the United States account for 4.8% of the total area in the commercial sector and are responsible for 10.3% of total energy consumption in this sector. The number of healthcare facilities increased by 22% since 2003, leading to a 21% rise in energy consumption and an 8% reduction in energy intensity per unit of area (544.8 kWh/m2). This study provides an analytical overview of the end-use energy consumption data in healthcare systems for hospitals in the United States. The energy intensity of the U.S. hospitals ranges from 640.7 kWh/m2 in Zone 5 (very hot) to 781.1 kWh/m2 in Zone 1 (very cold), with an average of 738.5 kWh/m2. This is approximately 2.6 times higher than that of other commercial buildings. High energy intensity in the healthcare facilities, particularly in hospitals, along with energy costs and associated environmental concerns make energy analysis crucial for this type of facility. The proposed analysis shows that U.S. healthcare facilities have higher energy intensity than those of most other countries, especially the European ones. This necessitates the adoption of more energy-efficient approaches to the infrastructure and the management of healthcare facilities in the United States.

The improvement of the technical equipment effectiveness is currently becoming particularly important. This applies not only to large and high-energy-intensive machines, but also to household appliances, the total energy consumption of which often exceeds the energy consumption of the overall equipment. These types of devices include, in particular, grinding and cutting equipment. The mathematical description of the processes carried out on this equipment is generalized and can be extended to a wider class of machines, including waste processing and mining equipment. The technological parameters, the design of screw grinders, and the processes of movement, deformation, extrusion and cutting carried out in them are characterized by a significant number of factors affecting the energy intensity. The main ones are the geometric parameters of the screw, machine’s body, cross knife, grinding plate’s thickness, the number and diameter of holes in it, as well as the product’s physical-mechanical characteristics and operating conditions. The most important for the mathematical description are the zones and processes where the main share of the consumed power is spent. The complexity of their analytical description is due to a simplified consideration of either individual technological zones of grinders’ existing designs, or the use of unreasonable simplifications.
