Description
[technical field]
The utility model relates to a kind of water heater that utilizes elevator brake resistance.
[background technology]
Chinese population is numerous, economic development is rapid, and the use amount of elevator and new increment have been all the maximum countries in the whole world.To 2012 the end of the year China have and surpassing 2,500,000 with elevator, annual newly-increased elevator is over 500,000.Elevator in use energy consumption is surprising, and for AC double-speed elevator, power consumption every day surpasses 80 kilowatt hours according to statistics, for the current synchronous elevator of gearless permanent-magnet power consumption every day of efficient energy-saving the most, also will surpass 40 kilowatt hours.Whole nation energy consumption of elevator every day surpasses 100,000,000 kilowatt hours, in " highly energy-consuming special equipment Energy Conservation Supervision management method " that country promulgates May 26 in 2009, classifies elevator as the highly energy-consuming special equipment.
