What is the damping net in a laminar air supply ceiling?

    The laminar air supply ceiling is an air supply end device in operating rooms and laminar flow wards, with high-efficiency filtration and flow equalization functions. Guided by Chinese standards, based on the size and shape of the operating room, the laminar air supply ceiling with a double-layer DPP damping net can effectively control the airflow speed above the operating area, form a vertical laminar flow effect, and effectively ensure indoor cleanliness (delivery The wind surface can reach level 100).

    A damping net is also called flow equalizing film, mesh plate, and flow equalizing net. It is often used at the outlet of the laminar air supply ceiling. It is composed of multiple metal or plastic lines, including aluminum alloy frame edging, stainless steel skeleton, and 150 mesh double layer. Damping net, circlip (when replacing, you need to measure the center distance of the circlip, and the aluminum alloy frame needs to measure the distance from the endpoint of the side length to the bevel position). Using damping nets helps to guide the airflow into a laminar flow state, avoiding dead corners and mixed winds, thereby better controlling the cleanliness to achieve level 10,000, level 1,000, and level 100.

    In addition, the damping net also has the advantage of energy saving. Traditional air conditioning systems usually require increasing the speed of cold air flow to improve the air supply effect, which results in a waste of energy. The damping net can achieve a more efficient air supply, reduce energy consumption, and reduce usage costs by adjusting the direction and speed of airflow.

    When selecting and installing damping nets, factors such as the size and layout of the room, as well as the air supply need to be considered. It is usually recommended to consult a professional air conditioning designer or engineer to select and install based on the actual situation. The following are common operating room laminar air supply ceiling manufacturing requirements:

1. The A-type box body is made of a cold-rolled steel plate with electrostatic spraying treatment. It serves as the outer shell and air inlet filter frame, including a double-layer DPP damping net and a medium-speed airflow compensation device.

2. The B-type outer box is made of SUS304 stainless steel, which is corrosion-resistant, acid-alkali-resistant, high-strength, and beautiful. At the same time, double-layer DPP damping and medium-speed airflow compensation devices are reserved.

3. The air supply ceiling damping layer flow equalization in the operating room can be selected from aluminum mesh plate, 304 stainless steel mesh plate, cold-rolled steel plate painted mesh plate, and double-layer DPP flow equalization net.

    In short, the damping net of the laminar air supply ceiling provides a clean, comfortable, and energy-saving indoor environment through reasonable airflow control. It can not only ensure the safety and health of indoor personnel but also effectively improve the atmosphere and comfort of indoor space.
