On May 16, 2022. Our machinery sales department went to our factory in Yingde, Guangdong, China. During the visit, we saw how the pre-insulated duct cutting machine is installed and packaged. Next, we will introduce you in detail and we sincerely hope you all can join us in the future.

The air duct system is the most important part of air conditioning and ventilation engineering. Its function is to transmit the conditioned air to the terminal equipment as efficiently as possible according to the designed flow rate. Generally, there are three shapes of duct cross-section: rectangular, circular and oblate.

The phenolic composite air duct has good thermal insulation, which can greatly reduce the heat dissipation loss of the air conditioner, which reduces the equipment capacity of the central air conditioning system.

According to the theory and technology of micro-perforated plate noise reduction, the composite board adopts laser micro-piercing technology to effectively reduce noise and can directly replace the muffler.

The installation method can be determined according to the actual situation on site, it can be hoisted in place as a whole, or the air duct can be placed on the bracket section by section, and then connected section by section.

1. The shrinkage of the PP-R pipe must be less than 3% when it is hot-melted, and the installation must meet the technical requirements of the manufacturer;
2. The pipes must be casing through the wall, De25 and De32 use PUC70 casing; De40, De50 and De63 use PUC110 casing; De75 and De90 use PUC133 casing;

he installation position of the air conditioner host should be convenient for maintenance, and it will not affect its use function, especially pay attention to heat dissipation. In the case of multiple hosts in the computer room, all the host computers must take over the direction and the operating surface in the same direction;

1. Confirm that the on-site civil structure has been completed and that there is no large amount of water used for construction.
2. Confirm that the professional construction of pipes, electrical, fire protection, etc. above the air duct is basically completed, so as to avoid a large number of cross-operations from damaging the thermal insulation.

The biggest difference between the inner insulation air duct and the outer insulation is that the insulation and the air duct are designed together to save the time of doing insulation separately. The construction period can be reduced. It is more suitable for engineering projects with high construction period requirements. It can effectively shorten the construction period and save time.

We see a lot of air ducts with a layer of insulation on the exterior. Why do we need insulation? In fact, there are many benefits to heat preservation. First of all, heat preservation literally means maintaining temperature. This temperature not only refers to heat, but also air conditioning. In particular, the air ducts connected to the central air conditioner (which can generally be seen in large supermarkets) must be insulated.
