America heat pump water heater can save more energy than Chinese heat pump water heater?The answer is not necessarily the case. The tenth session of the Chinese appliances water heater Branch Technology Conference held recently in Wuxi, A.O. Smith, on behalf of Jia Yongjie "between China and the United States share of household heat pump water heaterproduct energy efficiency evaluation of differences" report, the report shows the differenceAmerican heat pump water heater and heat pump water heater energy Chinese measurementmethod, the heat pump water heater energy efficiency evaluation standard is proposed due toour suggestion suit one's measures to local conditions.In recent years, heat pump water heater with its outstanding features in energy saving and environmental protection is very popular in the market, many manufacturers have poured into,the rapid development of the industry. However, the reporter learned in the interview, a lot ofenergy and get the heat pump water heater products consumers have expressed disappointment at the product, because the operation cost and energy saving effect of themanufacturers claim that far. Some people even suspect Shi Bushi because the heat pumpproduct is not good enough, so the efficiency of heat pump products, many of the America will be better.In this regard, Jia Yongjie Chinese and USA daily use hot water data for comparative analysis,put forward the "installation", "products" and "the energy efficiency evaluation method" is the impact of energy-saving products energy efficiency difference of the three main factors. "If youwant to reflect the heat pump water heater can make better use of the energy efficiency, one isthe efficiency of heat pump, and the other one is thermal efficiency," said Jia Yongjie. According to his calculations, to replace the traditional electric water heater using pure heat pump mode, ifa period of a month electricity consumption cost 1050 yuan, over the same period this year,consumption of electricity at a cost of 430 yuan, saving 144%. "The Ef test method of heat pumpof our products according to the calculated results and the efficiency of USA energy center is very similar, but if you use COP test method Chinese would be a lot worse," said Jia Yongjie,only to energy efficiency standards more appropriate really promote the popularization and promotion of energy-saving products, heat pump water heater manufacturers have expressed their expectations.In June 9, 2013, the National Standardization Management Committee issued a "GB of 29541-2013 heat pump water heater (is) energy efficiency limit value of the national standard of energy efficiency and energy efficiency grades", and formally implemented in October 1st this year.However, the reporter in the more than 30 companies recently by the China Appliance Research Institute held in the "2013 heat pump water heater products testing and certification work to get the message", GB/T 23137-2008 standard is scheduled to report 2014 batch of revision,revision of the main direction of change, will involve the power consumption under the condition of the insulation condition of power the project. GB/T 23137-2008 standard is mainly based on GB 29541-2013 standard.Home appliance technology conference is currently the highest standard of household electrical appliance industry technology event, is a broad platform for technical exchanges and explore thehome appliance industry, the continuation of the trend of the past two years, the theme of 2013 is energy saving, intelligent, informatization, automation equipment.[noun] relatedCOP: China market to the evaluation of heat pump water heater energy efficiency is generallyrefers to the coefficient of performance of the standard GB/T23137-2008, COP. Test method:COP: air dry bulb temperature of 20 DEG C, the wet bulb temperature 15 C, 15 C water tank, the water is heated to 55 DEG C, through collecting data, calculate the heat capacity of heat pumpand heat pump power consumption ratio, COP value.Ef: USA doe Ef test, also known as the 24 hours simulation test, simulation of the user in a day(24 hours) with hot water, the first is the six intermittent water, then the long time standby heat preservation operation. In this experiment, the total should be discharged 64.3 + 1.0gallons (243 + 3.8L) water (this value is equivalent to the average daily consumption America family hot water).
