Abstract
This paper investigates the overseas and domestic backgrounds for green design of water heater products, regulates the purposes and basic principles of eco-design of water heater products, and provides the eco-design requirements, eco-design procedure, major methods of eco-design, eco-design evaluation and improvement, and product information provision and sharing. This paper will provide the guiding targets for the water heater product manufacturer, standardize the enterprise behavior of water heater product, and lead the water heater product enterprise to implement the product green design, which is of great significance in promoting the transformation and upgrading of water heater product, enhancing the green manufacturing level and increasing the green product supply.
Highlights
With the enhancement of domestic living standards, the application of water heater in the industrial and civil buildings has become increasingly popular, and the water heater has already become one of the major household energy-consuming equipment
The green design of water heater products intends to optimize the environmental impact of water heater product and bring the environmental factors into the product design and development activity, so as to improve the environmental performance of water heater product within its life cycle
In 2015, China issued General Principles for Eco-Design Product Assessment (GB/T 32161-2015 [4]), regulating the principle and methods of eco-design products evaluation, and preparation methods of life cycle evaluation report. As per these two significant standards within the ecodesign field, and in combination with the present ecodesign development status of water heater industry in China, it is required to provide the detailed requirements upon the water heater products in accordance with General Principle and Requirements of Eco-Design for Products (GB/T 24256-2009), and ensure that the water heater product designed as per this standard conforms to the relevant eco-design requirements provided in General Principles for Eco-Design Product Assessment (GB/T 32161-2015)
Summary
In 2009, the European Parliament and Council of the European Union published Establishing a Framework for the Setting of Eco-Design Requirements for Energy-Related Products (ERP Directive No 2009/ 125/ EC), including the relevant contents of water heater. The overseas enterprises have already evaluated the ecological properties from the perspective of environmental impacts of product life cycle, while the domestic enterprises still evaluate the eco-design products as per the single index, such as without CFC, energy saving, low noise, and etc. It is still not the eco-design standards. (3) The product eco-design of overseas enterprises stays at the consciousness and concept level, and establishes the detailed and operable methods and assessment and management fundamental platform. (4) For the substitution of toxic and hazardous materials, the lead-free solder research has already been conducted in some units, but there are only lab results, and they are almost not promoted and applied
