Installing energy-saving feedback for elevators can effectively return the electrical energy generated by the elevator to the power grid. The energy-saving rate reaches 25% -45%. In addition, due to the absence of resistance heating elements, the ambient temperature in the machine room is reduced, and the operating temperature of the elevator control system is also improved, preventing the control system from crashing and extending the service life of the elevator. The computer room can no longer use air conditioning and other cooling equipment, which can save the power consumption of the computer room air conditioning and cooling equipment, save energy and environmental protection, and make the elevator more energy-efficient.
