Green Design Technology Refrigeration and Air Conditioning

Alloy materials, test methods, assembly production process and post weld inspection standards. 3 Evaluation of refrigeration and air conditioning refrigeration and air conditioning products, green design whether the design to meet the green requirements, the need for product performance, environmental performance, cost and other comprehensive evaluation of green design. Life cycle assessment (LCA) is an important part of green design J, refers to the selection of raw materials from the product,[link widoczny dla zalogowanych], design, production and use, maintenance and retirement of the entire life cycle of all stages of life cycle assessment, and evaluation results used to guide the design and manufacturing. LCA analysis of a particular product, including 4 34 2006 7 Fluid Machinery Volume 75: (1) defines the objectives and scope, including the LCA's goal, the establishment of the research products of the functional unit, set the LEA's boundaries and so on. (2) inventory, including the identification of products in various stages of the life cycle of all inputs (energy, raw materials) and outputs (products,[link widoczny dla zalogowanych], byproducts,[link widoczny dla zalogowanych], waste, etc.) data and to quantify. (3) evaluation factors, on the basis of quantitative analysis of the data, to translate into environment-related measurement data. (4) the results of evaluation of each factor on the most serious environmental problems to assess and improve the design of the proposed strategy. To accurately reflect the variety of product impact on the environment, green products to be evaluated with the following quantitative indicators 1O. (1) minimize the use of hazardous materials indicators. (2) the cost of cost indicators: the higher the cost of resource consumption will be greater. (3) reliability indicators: higher reliability, smaller damage on the people and the environment, maintenance, less damage to the environment. (4) material resource indicators: use of materials on the environment hostile to small, including the performance of renewable materials, recyclable and other properties and cleaning performance, such as steel, aluminum smaller than the hostile environment. (5) Product weight indicators: the heavier the material the more the occupation of resources, resulting in transport and scrap processing consumes more resources. (6) Product reuse after the end of life indicators: a shorter life expectancy will cause more material recycling more waste and resource consumption. Figure 1, the green design process refrigeration and air conditioning (7) production efficiency indicators: the more complex processing, lower productivity, energy, the greater the waste of materials. ( Cool

processing mode indicators: different processing methods produce different effects on the environment, such as electroplating than machining large damage to the environment. (9) material recycling performance indicators: materials can be recycled easily and affordably. (10) removable indicators: Products should be easy to disassemble. There is currently a lack of uniform international standards of green product evaluation, but Germany, the United States, Japan and other developed countries have developed a number of environmentally friendly products have market access system,[link widoczny dla zalogowanych], the value of the 10 indicators are mostly national or industrial standards with reference to the current value of the limit. To sum up, the green design process refrigeration and air conditioning available Figure 1. 4 Conclusion face of fierce market competition, export requirements of the environmental impact of non-tariff trade barriers, greater consideration should be the source of product design, production, use and impact on the environment after disposal, the use of green design, to meet market and consumer demand. The green design of refrigeration and air conditioning should be considered is the quality, functionality, life and environmental system design, help to promote the sustainable development of refrigeration and air conditioning industry.
