Reference Conditions for Elevator Selection
The first consideration is the appropriate number of elevators. It's well known that more elevators mean greater transport and load-bearing capacity between high-rise buildings, reducing passenger waiting times and arrival times. However, this doesn't mean more is always better. The number of elevators determines the developer's investment and daily maintenance costs. Therefore, the actual purpose of the high-rise building and expected passenger flow should be fully considered when selecting elevators. This ensures the elevators are used efficiently, meeting daily needs for going up and down stairs and transporting goods while effectively reducing operating costs.
Elevator Selection Methods
First, estimate the number of people in the high-rise building, calculating the actual traffic volume based on per capita usable area. Then, estimate the concentration rate of passenger flow requiring elevator use after the building is operational. Finally, calculate the total number of people needing elevators. When choosing a control method for elevator operation, analyze the actual usage conditions of the high-rise building and select from various control methods such as parallel operation, group control, single/multiple control, double-floor control, and centralized control.
General Principles of Elevator Selection The pace of life in modern cities is significantly faster, necessitating the availability of elevators for passengers under normal circumstances. This means that if one elevator malfunctions, other elevators should be available to transport passengers to the corresponding floors. For developers, initial investment cannot be too high. Therefore, elevator selection requires comprehensive consideration of various factors to arrive at a safe, reliable, convenient, and economical solution.
Methods of Elevator Selection First, a detailed calculation of the building's actual traffic volume is necessary. The traffic volume refers to the average number of people typically residing in the high-rise building, calculated based on the usable area per person. Second, estimate the building's internal passenger flow concentration rate. This is calculated by dividing the total number of passengers transported every five minutes by the building's average passenger flow, multiplied by 100%. Third, calculate the total number of elevator users, i.e., the average number of people typically residing inside the elevator during normal operation. Fourth, select the elevator control method. Currently, elevator control methods mainly include parallel operation, collective control, group control, single-level control, high-level control, double-level control, and regional service. In recent years, a more advanced operating method, neural network operation, has also emerged. Fifth, select the elevator specifications and number. Before formally calculating this, it is necessary to perform preliminary calculations and analyses on the average weight carried per cycle and operating speed of elevators in high-rise buildings similar to the building's transportation system, as well as their control methods. Based on these results, determine the number of elevators in the building area under normal operating conditions.
