Superconductive type fresh air machine for elevator

Abstract

The invention relates to the technical field of air conditioners for elevators, in particular to a superconductive type fresh air machine for an elevator. The superconductive type fresh air machine for the elevator comprises a fresh air machine body. The fresh air machine body is arranged at the top end of a lift car of the elevator. The fresh air machine body comprises a machine shell, a base plate and superconductive type centrifugal fans. An air suction opening and an air exhaust opening are formed in the middle of the machine shell. An air outlet and an air inlet are formed in the two sides of the base plate correspondingly. The base plate is arranged at an opening of the machine shell in a closing manner through screws. The two or more superconductive type centrifugal fans are uniformly arranged according to the air inlet and the air suction opening. A filter device is arranged between the air suction opening and the air outlet. The air suction opening and the air exhaust opening are each provided with a filter screen. By means of the superconductive type fresh air machine for the elevator, simplification and miniaturization of a fresh air system for the elevator are achieved; mounting difficulty, maintenance difficulty and cost are lowered; energy utilization efficiency is improved; and fresh air exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of elevator air conditioners, in particular to a superconducting elevator fresh air fan. Background technique [0002] Under the existing background technology, in order to ensure the circulation of the air inside the elevator and prevent accidents of insufficient oxygen when people use it, the top of the elevator is specially equipped with an independent elevator air conditioner to meet the above requirements. Higher requirements, not only to ensure that it can withstand the shaking of the elevator when it goes up and down, but also to be able to resist a certain impact and continue to work when an accident occurs, so as to prevent the air conditioner from causing hypoxia to the internal personnel when the elevator stops; and, Compared with household air conditioners, the maintenance of elevator air conditioners cannot be easily disassembled due to the particularity of the installation and use location, so ...

[0002] Under the existing background technology, in order to ensure the circulation of the air inside the elevator and prevent accidents of insufficient oxygen when people use it, the top of the elevator is specially equipped with an independent elevator air conditioner to meet the above requirements. Higher requirements, not only to ensure that it can withstand the shaking of the elevator when it goes up and down, but also to be able to resist a certain impact and continue to work when an accident occurs, so as to prevent the air conditioner from causing hypoxia to the internal personnel when the elevator stops; and, Compared with household air conditioners, the maintenance of elevator air conditioners cannot be easily disassembled due to the particularity of the installation and use location, so daily maintenance work is not easy to carry out, which undoubtedly increases the overall maintenance cost of the building

[0003] Not only that, in order to ensure that there is enough air inside the elevator, the volume of the elevator air conditioner is often too large. Although it will not add extra burden to the operation of the elevator, due to the existence of its own weight and the misalignment of the center of gravity, the elevator air conditioner still has a certain amount of power when the elevator is running. will have the additional effect of
