Recently, the reporter learned from the Samsung Elevator Company of Yangzhou Economic and Technological Development Zone that the solar elevator independently developed and produced by the company has been put into use. This new elevator using solar energy as driving energy may change the elevator industry in the future.
Two battery panels pull the big elevator
What's the difference between solar elevators? Yesterday, in the office building of Samsung Elevator Company, the reporter saw this solar-powered plastic-coated elevator. Except for two solar panels, at first glance, its appearance is no different from ordinary elevators.
"As the country attaches importance to energy conservation and environmental protection, we have also seen business opportunities in the combination of green energy and the elevator industry." Shi Fengming, chairman of Samsung Elevator, revealed to reporters that the main energy for solar elevators comes from solar panels, which are converted by absorbing solar energy. It is converted into electric energy and then converted into direct current through the inverter, which is used for the operation of the elevator.
What should I do when there is no sun on a cloudy day? Should solar elevators be "shut down"? "By converting solar photovoltaic panels, storing electrical energy in batteries can keep the elevator running for 1-2 days." Shi Fengming told reporters, considering the South When continuous rainy days or insufficient energy, this elevator is also equipped with automatic power switching. "If the battery power is insufficient, switch to the power grid to ensure the normal operation of the elevator."
Super energy saving: the energy consumption is equivalent to a rice cooker
Depending on the load capacity, the power of the elevator motor can range from five to six kilowatts to more than ten kilowatts. How do two small battery panels drive an elevator?
"The solar elevator not only adds battery panels to the outside but also adds a small heart' to the core." Shi Fengming told reporters that if the electric energy converted by the two solar panels cannot operate at all according to the original elevator design, the only way to reduce the motor power is Just work.
"The elevator industry has developed for so many years, but the essential principle has not changed. Steel cables are used to drive elevators up and down. After using steel cables, the drive wheels are larger and the motor power is also very large." Shi Fengming introduced to reporters that if it is driven by solar energy, The bottleneck of the elevator industry must be overcome and the power of the elevator motor must be reduced. To this end, Samsung Elevator Company introduced a plastic-wrapped steel rope imported from Switzerland.
Shi Mingfeng told reporters that this is a kind of steel core wrapped with a layer of polymer plastic, which reduces the weight of the steel cable and also reduces the friction during operation. Similarly, the driving wheel becomes smaller and the motor power is naturally reduced. "Shi Fengming calculated an account for the reporter. A solar elevator with a carrying capacity of about three or four people consumes the same energy as a 750-watt rice cooker so that two solar panels can drive it.
The solar elevator has been in trial operation in Yang
It is understood that due to the application of new energy sources and new designs, solar elevators are still cutting-edge products in the industry. The famous American elevator manufacturer Schneider launched his own solar elevator last year, and Yangzhou people are considered to be ahead of their domestic counterparts this time. Shi Fengming told reporters, "Although solar elevators have not been officially put into the market, currently four or five of them are in trial operation in Yangzhou, and the results are good.
With the popularization of the use of new energy, the market prospect of solar elevators is very broad. "This kind of elevator is mainly suitable for villas, small clubs, and as barrier-free elevators." Shi Fengming said that because of the low dependence on electric energy, solar elevators can also be applied to special fields. “For example, after a fire in a building or a power outage for other reasons, this kind of elevator that does not depend on electrical energy can still be used normally and can be used as an emergency elevator.” Shi Fengming told reporters that according to the current cost, the cost of this elevator has increased slightly by about 20%. "Although it is slightly more expensive, it will save a lot of electricity consumption every year, and the price difference will be paid back after a few years of use."
