"heat Pump Water Heaters For Household And Similar Purposes," National Standard Of Air -

Is the relay water heaters, gas water heaters and Solar Energy Water heater after the "fourth generation water heater"

, it exists in the air (or water) of renewable, low-quality Energy The utilization rate of 60%? 80%, is an efficient Energy Heating fish. With a unit of electricity can be generated by electric water heater with hot water equivalent to 4 units of electricity generated by water, saving of 75%. In addition, the heat pump water heater with water separation technology, high safety factor, and heat from the air (or water), without any air and water emissions, will not cause environmental impacts.

As an efficient energy-saving devices, heat pump water heater in the international market occupies an important position, use of air (water) source heat pump water heaters produce hot water not only can save energy, and can "load shifting" to ease tension power grid, so in the domestic market has a broad development space and applications.

Our country is in a period of rapid economic development, rapid growth of energy demand on the availability of energy resources, carrying capacity, and national energy security poses a severe challenge.

Heat pump water heaters, energy saving effect is remarkable, but the current lack of standards in the industry, not only affect the further promotion of heat pump water heater, and returned to "fish in troubled waters" are an opportunity to exploit. In the absence of relevant national product standards, all manufacturers have the technical parameters according to their own production, resulting in a heat pump water heater market, product quality, good and bad, in the production and technical identification of the lack of metrics.

To help government departments in enterprise market Marketing Behavior, and promote the sound development of energy-saving products market, consumer protection from damage, especially to develop "heat pump water heaters for household and similar purposes," the national standard.

"Heat pump water heaters for household and similar purposes" by the National Standardization Technical Committee centralized management appliance, the implementation of the National Standardization Technical Committee appliances organization and leadership, standard-setting working group was established in January 2007 and work organization. Team Leader as a unit by the China Household Electrical Appliances Research Institute, the working group drafting the mainstream of production by domestic enterprises and a total of 21 members of the testing organization units. Drafting process, the drafting group held five meetings and amend standards, in the investigation of the heat pump water heater products and a large number of verification tests, based on advanced foreign technology, and based on our current technology level heat pump water heater to determine the corresponding Specifications and test methods, in September 2008, the standard was finalized. In the industry by openly solicited the views of this standard, in October 2008 National Household Appliances Standardization Technical Committee Technical Committee of refrigeration and air conditioning equipment sub-standard Draft for Approval by the annual audited and submitted to the Standardization Administration Committee for approval. December 30, 2008, the National Standardization Management Commission approved the release GB/T23137-2008 "heat pump water heaters for household and similar use of" national standards, and in September 1, 2009 into effect.

The standard in the preparation, the heat pump part of the performance parameters and test methods for the main reference GB/T7725 "room air conditioner" in the relevant provisions, water tank part of the performance parameters and test methods for the main reference GB/T20289 "storage-type electric water heater "in the relevant provisions. Determine the specific parameters of the experiment through the molding product obtained by means of comparison, the overall structure of the national standard format in accordance with product development performance.

Standard defines the basic structure of heat pump water heater products, users are more concerned about form as well as basic performance characteristics of heat pump water heater, and describes the measurement of these features standard methods, including the product model name, run the test conditions, performance parameters measurement and calculation methods, as well as evaluation of the performance of heat pump water heater products, provide relevant testing methods and determine the basis.

For heat pump water heater products, technical requirements, standards, mainly for the following requirements:

1. As a general requirement, the first heat pump water heater products to meet safety and electromagnetic compatibility standards, and in the heat pump water heaters are not allowed to use the process caused by water pollution.
