1. Several issues that should be paid attention to during prefabrication (1) The bite form of the thin steel plate air duct in the clean system should adopt single bite, corner bite and combined corner bite with small bite seams.

1.Air System Design Principles ★It can guarantee the required indoor parameters, that is, it can guarantee to meet the indoor temperature, relative humidity, purification and other requirements under the design conditions and operating conditions.

Using a pre-insulated duct CNC cutting machine will definitely improve your duct making efficiency. A pre-insulated duct CNC cutting machine is a computerized cutting machine that cuts fast and accurately.

Fiberglass Duct Board is a 1- to 2-inch-thick rigid board (manufactured from resin-bonded inorganic glass fibers) used for the fabrication of fiberglass ductwork. For commercial applications that require thermal insulation, condensation control, and acoustic control, fiberglass duct board provides a low-cost, efficient alternative to sheet metal.

1. Shops and public areas Large shops and department store areas generally use an independent all-air system, and the exhaust system is designed independently. The exhaust air volume is calculated as 80% of the fresh air volume. Select a fan.

1.Design of condensate system The condensed water generated in the operation of fan coil units, integral air conditioners, combined air conditioning units, etc., must be discharged in a timely manner. The design of condensate discharge pipe adopts open, non-full flow artesian system.

1.Rubber-plastic sponge insulation process ① First, wipe the surface of the air duct clean, wipe off the dust and accumulated water on the surface and let it dry; ② Cut the insulation material according to the size of the air duct, and cut the material according to the regulations of pressing the long side to the short side;

The concept of ventilation systems consists of ventilation ducts and all the components and equipment necessary for their function. They consist of all the components through which the air circulates, such as ventilation pipes, accessories, ventilation shafts and ducts, mufflers, fans, air conditioning devices, fire dampers and other closing devices against the transmission of fire and smoke and closing devices against smoke transmission (smoke dampers) as well as their connections, fixings, insulating layers, fire-stop linings, vapor barriers, sheets, linings and linings.

1.Selection principles and precautions First of all, the flow rate and pump head of the highest operating condition must be satisfied, and the working state point of the water pump should be in the high efficiency range. The flow and head of the pump should have a margin of 10-20%.

Using a pre-insulated duct CNC cutting machine will definitely improve your duct making efficiency. A pre-insulated duct CNC cutting machine is a computerized cutting machine that cuts fast and accurately.

1. Unable to connect: Because the air duct cannot be connected, it has many advantages such as tight connection joints, good quality of joints, light weight of joints, material saving, simple construction process, saving man-hours, easy to achieve full mechanization, automatic construction, low construction cost and many other advantages, so it has been widely promoted.

1.Cooling water circulation system The outlet temperature of the cooling water of the condenser can generally reach above 37°C. The high-temperature water is cooled by the cooling tower to the inlet water temperature required for cooling the condenser of the chiller, and then sent to the chiller for recycling through the cooling water pump.

HVAC systems (or heating, ventilation and air conditioning systems) are responsible for heating, cooling or circulating air in all types of buildings, both residential and industrial. These systems usually have a considerable network of ducts to transport and distribute the air, so it is essential that these are well insulated for everything to work properly.
