The power consumption of air conditioning equipment in the computer room for general users is about 4KW. It operates for 300 days a year according to demand, with 12 hours of operation per day, resulting in a total electricity consumption of 14400 kWh per year. In many places, the cost of purchasing, consuming electricity, and maintaining air conditioning in computer rooms alone is a significant expense. And the elevators in the community are not all generating electricity at the same time. Some elevators are generating electricity while others are using it up. The total electricity meter of the property measures the electricity consumption of the external power grid, which will reduce the total meter measurement and correspondingly decrease the payment to the power company.
2. Elevators have become the second largest consumer of electricity in today's society, second only to air conditioning, accounting for about 20% -30% of the community's public electricity consumption. At the end of 2016, the number of elevators in China exceeded 4.5 million, making it an international elevator powerhouse with a market share of 60% worldwide. Elevator energy conservation has become an important category of social energy conservation in China. A typical elevator consumes about 30-80 kWh of electricity per day. Based on an average daily power consumption of 50 kWh per elevator and an annual operation of 300 days, with 4 million units in use nationwide, the daily electricity consumption of elevators is 200 million kWh, which is 60 billion kWh per year! The consumption of electricity exceeds two-thirds of the annual power generation of the Three Gorges, indicating the huge power consumption of elevators! Therefore, it is very necessary to save energy in elevators in practice.
The impact of energy feedback equipment on elevators:
1. It will not affect the normal operation of the elevator at all.
The energy feedback device will not alter any circuits or wiring of the elevator's original control system. Simply connect the input end in parallel to the high-voltage DC bus of the elevator's frequency converter discharge, and connect the output end in parallel to a 380V power switch.
The energy feedback device intercepts and recovers the high-voltage DC waste electricity released by the frequency converter to the high-power braking resistor during the operation of the elevator. After rectification, inversion, and filtering, it forms a new regenerated electric energy feedback and is used to repair the three-phase public power grid in the building. This achieves the energy-saving effect of the elevator and will not affect its normal operation.
