Water Heater Performance Test
Resolution: storage type electric water heater national standards for energy efficiency – the storage type electric water heater, that is, water electric
2006 End of the year, China has begun to "storage type water heaters of the limit value of energy efficiency and energy efficiency rating, the workplace standard, and approved by the Development and Reform Commission (NDRC), Organization United Nations Development Programme (UNDP), Global Environment Facility (GEF), co-sponsored by China to end-use efficiency project Energy (EUEEP) support. June 2007, the National Standardization Management Committee formally approved the "storage type electric water heater to limit the effectiveness and value energy efficiency rating of the project, the end of 2007, after the standard preparation group effort, " storage type electric water heaters reduce the effectiveness and value of energy efficiency rating "The completion of the development and approval, April 1, 2008, GB21519-2008 "type storage electric energy efficiency of hot water and limit the level of efficiency energy values, "and is scheduled for November 1, 2008, indeed. The scope and parameters of evaluation of the effectiveness Energy Today, people use the heater for the hot water heater main type electric or thermal heat pump Water heaters are also the momentum of rapid development, such as temperature and electric water heater is energy saving, compact saves time by industry and other factors relate. Given the nature hot pump type electric water heater with a hot water storage type works with the evaluation objectives and difference, experts and businesses have agreed to offer three types of heaters on the development of efficiency standards energy. Therefore, GB21519-2008 "type storage of electrical energy efficiency of water heaters and energy efficiency level limit value "shall apply to storage type electric water heaters and other auxiliary energy water heaters Electric. The use of electric water heaters as a supplementary energy sources, such as auxiliary heating with solar water heaters Electricity does not apply to this standard. The standard edition is indicated "no heat insulation for water heaters does not apply this standard (IEC60379 similar description), but given that there are still production in China electric water heater and the tank without insulation between the products, if there is no insulation on the water heater does not apply to this standard, the standard does not cover this part of the water heater, which makes some of the non-integration products have hot water storage tank under control, may cause some negative effects, so that the removal of the project for approval "without insulating the water heater does not apply to this" Standard, both to meet the requirements techniques, if the installation of insulation, what materials to add a thickness of companies themselves. And storage type water electric heaters energy efficiency related technical indicators are: the loss of energy inherent 24 hours (24 hours factor inherent energy), the rate of hot water heating efficiency. In addition, the energy consumption of hot water storage of electric type and usage patterns of a great relationship, if a control technology energy saving developed by a control device for saving energy to save energy also play an important positive role, such as insulation technology high technology intelligent booking, technology temperature insulation, heating technology layers of electrical technology night, variable capacity technologies. Most countries with an energy loss of 24 hours involved in assessing the effectiveness storage-type electric power water heater energy consumption, Australia, in addition to the inherent 24 hours, while assessing the outflow rate of water the United States is a set of six water discharge standard simulation program for evaluating the electrical consumed by the storage type electric efficiency of water heaters. test methods of energy consumption point of view, the most losses energy inherent in the method of testing 24 hours and national IEC60379 "Performance measurement of the water heater, similar to the temperature varies, the location of test points are not the same. United States, the most unique test method can simulate the use Consumer state power, but the extent of complex, tedious, expensive tests. Thanks to international standards of research, discussion and type storage efficiency of electrical energy of the heater of the verification test to determine China "value-type storage limit of electric water heater energy efficiency and energy efficiency rating "assessment of the effectiveness indicators Energy: 24 hours inherent coefficient and the rate of consumption of hot water. Energy efficiency test methods to maintain and GB/T20289-2006 "thermal storage type electric water," coherence, the inherent energy efficiency standards From 24 hours to test methods of energy consumption, hot water output rate of test methods even as much as possible with GB/T20289-2006, but because GB/T20289-2006 coverage testing product is limited, and local representation is not very clear, easily lead to misunderstandings, to GB/T20289-2006 energy efficiency standards on the basis of improved testing methods, including the following points.
