Description

Layered ventilation heating and cooling system for tall and large spaces

technical field

The utility model belongs to the technical field of ventilation equipment, in particular to a layered ventilation heating and cooling system for tall and large spaces.

Background technique

With the improvement of production technology, the production capacity continues to expand. High and large space industrial plants are becoming more and more common. There are more and more high and large space plants with a space height of 12-16 meters and a width of more than 100 meters. In these high-space workshops, the height below 2-3 meters from the ground is where the staff are located. Most of the equipment and items are also arranged in this height range, and the air resistance is large. The working area environment of the staff is poor.

Traditional ventilation systems usually use roof fans or ventilation ducts to ventilate, adjust temperature, remove smoke and toxic gases, and cannot achieve sufficient ventilation; even the more advanced airflow that is increasingly used Although the push-carry ventilation system can achieve sufficient ventilation improvement, the ambient temperature does not drop or increase.

Some large-scale industrial plants also adopt heating systems and air-conditioning systems for large spaces. The commonly used airflow organization forms include layered air-conditioning, displacement ventilation, vertical wall-attached jet flow, and common side-supply and side-return forms. However, due to the limitation of the installation location of the equipment, the cold air or warm air cannot reach the activity area of about 2 meters. The above-mentioned heating systems and air-conditioning systems for large spaces are still calculated according to the heating systems and air-conditioning systems of full-height spaces. In actual use, the power consumption is large and the operating cost is high.

In addition, some existing ventilation systems still have a relatively simple control process, relying only on manual adjustment, without intelligent control, and consume a lot of energy.
