Embodiment Construction

[0014] Principle of shaft ventilation: Wind energy drives the wind turbine to rotate. The shaft effect improves the exhaust efficiency. The fresh air blower evenly sends in fresh air. The lower exhaust port makes the shaft form a downward exhaust air flow. The lower exhaust fan of the car makes the inside of the car rise when waiting. Exhaust air flow under the wind.

[0015] Principle of car ventilation: operating state, The lower exhaust fan of the car is stopped, the fresh air shutters of the car are opened to the wind according to the driving direction, and the upper part of the car sends air and the lower part exhausts air. In the waiting state, the lower exhaust fan of the car is turned on.

[0016] Principles of architectural design:

[0017] 1. The doors and windows of the elevator machine room on the roof are sealed;

[0018] 2. The exhaust system is higher than the roof of the machine room, and the new fan is lower than the roof of the machine room. The fresh air and exh...

Abstract

The invention relates to a lift shaft capable of ventilating by wind power and a lift ventilating method. The lift shaft is provided with a new air pipeline and an air exhausting pipeline. A new air port is arranged corresponding to a position of a floor and the upper part of a lift car. When the lift runs, a lower exhaust blower stops running. A new air shutter in the lift car is started facing to wind based on the running direction. Air flow with ascending air supplying flow and descending air exhausting flow is formed in the internal part of the lift car, so that energy consumption is saved and respiratory tract infection of passengers and bad influence of odor are effectively prevented. The shortcomings that the lift shaft is damp and the lift car is stuffy are overcome. Therefore, the method disclosed by the invention can be widely applied to ventilation of lift shaft and lift car and the lift shaft can be manufactured in an industrial, standard, universal and serial manner. The invention belongs to the fields of buildings, building ventilation and lift manufacturing.

Description

technical field [0001] The invention relates to an elevator shaft ventilated by wind energy and an elevator ventilation method thereof. The shaft is provided with a fresh air duct and an exhaust duct, and a wind turbine is used to form an exhaust air flow at the lower part of the shaft to supply air evenly. The upper part of the elevator car is provided with adjustable fresh air louvers. Exhaust air from the lower part of the car exhaust fan. It can be widely used in the ventilation of elevator shafts and elevator cars, can realize industrialization, standardization, generalization and serialization manufacturing, and belongs to the field of building and building ventilation and elevator manufacturing. Background technique [0002] Existing elevator shafts do not have a ventilation system, and the elevator machine room on the roof restricts the use of the efficiency of the elevator shaft chimney. Most of the cars use electric fans for one-way ventilation, which makes breathi...
