subject: Million And Re [print this page] Recently, the largest gas appliance manufacturer million and the Group's external claims, the thermal efficiency of 1.05% of the condensing water heater in the million and successfully developed, this result has just passed the National Test Center of gas detection equipment. It is the first year following the successful development of over 100% thermal efficiency condensing gas water heater, the million and re-condensing water heater thermal efficiency will increase 2 percentage points to 105.5%, thus breaking the record of saving gas water heater in the world.
However, according to the law of conservation of energy principle, only the highest thermal efficiency is 100%, why can exceed 100%? And according to national standard GB6932-2001 "Domestic gas instantaneous water heater" in the traditional gas water heater's thermal efficiency requires only 80%.
This, the national gas appliance inspection and testing center, said a senior engineer, China adopted national standards for the provisions of the European standard to calculate the thermal efficiency is a significant degree of heat to be used as the basis, the calculation of latent heat is not within the scope. Now condensing water heater to the latent heat used up, according to national standards, calculation of thermal efficiency formula in the denominator is still "was hot", but who had become a "sensible heat" plus "latent heat", so the thermal efficiency may well break 100%. Million and the recovery of the original is no more use of latent heat, making use of the "latent heat + sensible heat" is greater than the denominator "sensible heat", it broke through the 100%.
Million and Group President Luchu Long also cited the example image: "It's like when reading test, even though only 100 points out of, but You Jidao additional questions, the difficulty over the curriculum requirements, students may choose to do and do not do to students with outstanding ability to score more than out of a lot of people, 10 000 and is doing a condensing water heater that additional problems Road, on the breaking out of 100% of this limit. "
It is understood that since the formal launch of the market, 10 000 and condensing water heaters have received many awards: Jul. 2006, by Foshan municipal government issued the "2005 Science and Technology Progress Award, Foshan City, the first prize"; August by the industry big ratings, issued by China National Hardware Association's "Top Ten Gas innovative models" title; in November, was selected by Guangdong Economic and Trade Commission, "Innovation Funds in 2006 at the provincial level key industrial technology innovation project", given special awards. Recently, Wan and condensing water heater, Guangdong Province Science and Technology Evaluation Center also organized "critical areas of Guangdong and Hong Kong in 2006 breakthroughs project" bidding to become the only bid with a type of product, access to nearly 200 million project support costs.
