Classification of ventilation equipment
Release time:
2021-04-21
A common ventilation device in our lives—the ventilation constant pressure machine—uses mechanical or natural methods to deliver sufficient fresh air into indoor spaces while simultaneously exhausting foul air that does not meet hygiene standards. This ensures that indoor air quality meets hygiene requirements and production process needs. The ventilation facilities within a building are collectively referred to as ventilation equipment; they not only provide good ventilation but also offer economic advantages. Many people are not very familiar with the classifications of ventilation equipment. A good classification of ventilation equipment is beneficial for its future use.
A commonly used ventilation device in our lives—Ventilation constant pressure machine, is a method of using mechanical or natural methods to deliver enough fresh air into the indoor space, while discharging unclean air that does not meet hygiene requirements, so that the indoor air meets hygiene requirements and production process needs. The ventilation facilities in the building are collectively referred to asVentilation equipment，not only has good ventilation effect, but also has economic advantages. Many people don't understand the classification of ventilation equipment, doing a good job ofVentilation equipmentClassification is beneficial for later use.
So let's briefly understand the classification of ventilation equipment:
1. Fans can be divided into negative pressure fans, low-pressure fans, medium-pressure fans, and high-pressure fans according to pressure.
2. In fact, fans can be divided into centrifugal, axial flow, diagonal flow, and cross flow types.
3. According to the direction of airflow entering the impeller, fans can be divided into diagonal fans, axial flow fans, and centrifugal fans.
4. Fans can be divided into single-stage, double-stage, or multi-stage pressure-boosting fans according to the pressure-boosting method.
5. Fans can be divided into axial flow fans, mixed flow fans, roof ventilators, and air conditioning fans.
6. If the equipment is made of material powder, it can be divided into:Iron shell fans, namely ordinary fans, fiberglass fans, plastic fans, aluminum fans, stainless steel fans, etc.
7.According to mechanical ventilation products,Ventilation equipmentCan be divided into fiberglass fans, fire exhaust fans, mixed flow fans, centrifugal fans, negative pressure fans, explosion-proof fans, corrosion-resistant fans, exhaust fans, exhaust fans and other products.
8. According to the ventilation range, it can be divided into comprehensive ventilation and local ventilation. Comprehensive ventilation, also known as dilution ventilation, is to ventilate the entire space. Local ventilation is to collect polluted air directly at the place where pollutants are generated and discharge it outdoors，or directly supply fresh air to the local space. Local ventilation has the advantages of good ventilation effect and saving air volume.
