What is Auto duct line 4? Principle and advantages and disadvantages of air duct air conditioning

Durmapress recently welcomed a delegation from Mongolia, marking their first visit as a new client specializing in construction and HVAC equipment. Their visit focused on evaluating our metalworking machinery, including the metal shearing machine, angle iron roller, 3-inch duct production line, press brake, and fiber laser cutting machine.

Client Background & Objectives

The Mongolian client, a key supplier of 3-inch ducts and structural components for infrastructure projects, sought equipment to enhance production efficiency. Their goals included:

– Testing metal shearing machines for cutting thick steel plates.

– Evaluating angle iron rollers for shaping 3-inch duct supports.

– Verifying fiber laser cutting machines for precision sheet metal processing.

Factory Tour Highlights

In addition, the customer showed great interest in our angle iron roller, which is perfect for forming angle irons used in construction and industrial applications. We demonstrated how it smoothly bends various metal profiles with minimal deformation.

The customer also reviewed our capabilities in fabricating 3 inch ducts, which are commonly used in HVAC systems. Our machines ensure high precision and airtight seams, which are essential in ductwork production.

Of particular note was the demonstration of our high-precision press brake, which features multi-axis control and user-friendly programming. This machine is capable of handling complex bending tasks with repeatable accuracy.

Finally, our Fiber Laser Cutting Machine was presented in action, cutting through stainless steel and carbon steel sheets with clean edges and high speed. The customer was impressed with its performance and ease of operation.

– Verifying fiber laser cutting machines for precision sheet metal processing.

On-Site Order & Client Feedback

After in-depth discussions and hands-on evaluation, the Mongolian client expressed strong confidence in the quality of Durmapress equipment and decided to place an order immediately. This included multiple machines tailored to their production needs.The client placed an immediate order for:

– 2 units of 6x2500mm metal shearing machines.

– 1 angle iron roller system optimized for 3-inch ducts.

– 1 fiber laser cutting machine (3000W).

At Durmapress, we are committed to building strong international partnerships and providing reliable solutions for sheet metal processing. We thank our Mongolian guest for their trust and look forward to supporting their production goals.

What is Auto duct line 4

First of all, “air duct machine” is a kind of air conditioner, that is, “air duct machine air conditioner”. Because its volume is larger than the general air conditioner, it is generally hidden in the ceiling, so it is also called “hidden air conditioner”.

In a nutshell, its operating principle is air conditioning through the air duct to the indoor air supply. High static pressure fan is adopted, the static pressure is positively correlated with the air supply head, that is, the greater the static pressure, the longer the air supply head. At this time, high static pressure air supply is far away, but the air duct needs to be longer. The reason why the high static pressure fan is used is to keep the wind pressure delivered to the room from being physically lost in the process of passing through the duct, otherwise the wind sent to the room will be very small.

Specifically, indoor/outdoor units in the air duct air conditioning system are composed of one to one configuration. The outdoor unit is composed of a compressor and an air-cooled condenser, while the indoor unit is composed of an evaporator and a circulating fan. The condenser of the outdoor machine is used to cool the air, and the condenser is connected with the indoor evaporator through the steel pipe, and then sends the cold air to each room through the indoor air supply pipe, and then sends the cold air back to the indoor machine through the return air pipe. At this time, the hot air is cooled and mixed with some fresh cold air and then output the air pipe, so it has been circulating. In addition, the air duct can be evenly arranged in the room according to the indoor space.

The shortage of air duct machine

1. The power consumption of the air duct machine is relatively large. Like ordinary air conditioning, it adopts fixed-frequency technology and consumes quite a lot of power if it is opened for a long time

2. Because the air duct system is indoor and outdoor one to one, if the indoor unit is installed more, there must be enough outdoor unit position, which will also affect the outdoor beauty.

3. The device is noisy.

The above is xiaobian to explain the common sense of air duct air conditioning to you. Now there is no deeper understanding of it, or after measuring the advantages and disadvantages of the air duct machine, it is decided to install a device at home!
