Comprehensive consideration of the elevator chosen by the developer

At present, when many elevators are selected, the cost of civil construction is high, the cost of elevator equipment is high, the cost of maintenance is high, and the electricity cost of elevators has become the biggest problem in the use of residential elevators in the country. The currently used elevators are very large in terms of overall cost, and the use fee is also very large. We choose the famous brand vvvf elevator according to the 9-story house to calculate: civil construction requires concrete shafts and machine rooms, the civil construction cost should be 80,000 to 100,000 yuan, and because the construction height is declared, it can not be super high, so there is one less floor. The price of elevator equipment is 180,000 to 220,000 yuan, the installation cost is 25,000 to 30,000 yuan, plus the total cost of transportation and other costs should be around 24-260,000 yuan. The two comprehensive costs reached about 350,000 yuan. Elevator use cost: The motor power is 15kw, that is, it requires 15 degrees of electricity per hour, plus lighting and others, and the power consumption for one hour of use is about 20 degrees. In addition, residential elevators generally calculate electricity charges based on industrial electricity charges, with prices ranging from 0.8-1.2 yuan/kWh.

Elevator maintenance: Famous brand elevators require 500 yuan/set maintenance fee, maintenance cost 6000-10000 yuan/year, so the use fee is amazing. Generally, the developers have never carefully calculated these accounts, and there is no elevator usage fee in the sales brochure. For this reason, many residents feel that the elevator fee is too high when they pay the property management fee, and the property company has no way. . If we choose the elevator without machine room for the same 9-story house, we will calculate another account: Comprehensive cost: Civil construction does not require concrete shafts, only frame structure plus brick walls, civil construction cost can be reduced by about 50,000 yuan; if permanent magnet synchronous without gear is used The price is only 200,000-220,000.

The overall cost is only about 28-30 million. More importantly, the usage fee is much lower. Generally, the power consumption of this type of host is only 50%-65% of that of ordinary vvvf. If you press 1000kg in 9 layers. For the 1.0m/s elevator calculation, the motor power only needs 6.7kw, and the electricity fee is only 40% of the famous brand elevator, the usage fee is greatly reduced; and the maintenance fee of the gearless host can also be saved. Especially in the current situation of China's energy shortage, not only choose better elevators, but also save energy, coupled with reduced development costs and reduced user fees, why don't developers do everything they can do?
