Problems solved by technology

However, the above various technologies cannot effectively improve the air environment in the car. Unlike other environments, the air environment may cause greater harm to people's health in a short period of time. The car is a public place with a high infection rate
At present, the axial flow fan is usually used to mechanically ventilate the elevator car to improve the air environment in the car, but due to the limitation of the auditory environment requirements, the amount of mechanical ventilation cannot be very large, which can only improve the air condition in the car to a limited extent. Air environment, and mechanical ventilation consumes a lot of energy, which is not conducive to energy saving
