Air Conditioning Ventilation Ducts

1. Common material classification

Galvanized steel sheet: The most widely used, it features corrosion resistance, high strength and easy processing, and is suitable for most general construction scenarios.

Stainless steel: It has stronger corrosion resistance and is suitable for high-temperature, high-humidity or environments with cleanliness requirements, such as food processing plants and medical facilities.

Composite air ducts: Composed of insulation materials and outer protective materials, they have excellent thermal insulation and heat preservation performance, are easy to install, and are mostly used in commercial complexes.

2. Core considerations for material selection

Environmental adaptability: Stainless steel is preferred for humid environments, while galvanized steel plates are suitable for ordinary office Settings.

Cost control: Galvanized steel sheets offer high cost performance, while stainless steel is relatively expensive. It is necessary to balance the cost in combination with the budget.

1. Core performance indicators

Ventilation efficiency: It depends on the cross-sectional area of the air duct and the wind speed design, and needs to meet the indoor air replacement requirements.

Thermal insulation: Composite air ducts come with their own insulation layers, while metal air ducts require additional insulation materials to reduce energy loss.

Noise reduction effect: By optimizing the curvature of the air ducts and installing sound-absorbing structures, the noise generated by air flow is reduced.

2. Performance optimization direction

Wind speed control: Set the wind speed reasonably to avoid excessive noise or increased energy consumption caused by excessively high wind speed.

Energy-saving design: Low wind resistance structure and high-efficiency insulation materials are adopted to enhance the overall energy-saving performance of the system.
