Abstract

The invention relates to a ventilating air-conditioning system of a large welding workshop, which substantially comprises induced fans blowing in multi-angle mode and disposed in each span of the workshop, roof exhaust fans are correspondingly arranged on a roof, and a large ventilating airflow formed by the induced fans and the roof exhaust fan workshop is an induced type single-way flow. An air-conditioning tail end is installed at each working position and communicated with an air-conditioning machine case through an air supply pipe. A partial air exhaust cover is disposed above a welding frame of the workshop, communicated with a fan box through a pipeline and combined with supplied air at the air-conditioning tail end to form a small airflow In local blow-suck type ventilation mode. The ventilating air-conditioning system of a large welding shop substantially has the advantages of 1 ensuring the minimum number of times of ventilation of the workshop, 2 providing workers with a conformable working environment, 3 not only removing harmful substances but also lowering the temperature in working areas, 4 ensuring safe production, and creating a comfortable thermal environment in the working areas. In addition, the temperature in the working areas is adjustable and controllable, and the system is energy-saving, reliable and low in cost.

Description

technical field

[0001] The invention relates to a ventilation and air-conditioning system, in particular to a large-scale welding workshop ventilation and air-conditioning system, which ensures the safety, health and comfortable environment of workers. Background technique

[0002] At present, the welding workshop is mainly based on local exhaust and local air supply, supplemented by comprehensive ventilation to improve the labor hygiene environment of the welding workshop, and most of them use mechanical ventilation in the form of jet flow, which consumes a lot of power and high operating costs. At the same time, due to unreasonable design and imperfect operation management, the expected ventilation effect cannot be achieved, the concentration of harmful substances is high, and the temperature in the workshop with a large amount of waste heat is higher than the temperature requirement of the working environment.
