Soth air duct is easy to use and fireproof

I accompanied my friends to visit air-conditioning shopping malls abroad. We went to some buildings including shopping malls, supermarkets, factories, etc. and found that they all installed the same type of air-conditioning duct: this kind of 'cloth bag'-shaped duct looks really good, not only convenient to install , Has the advantages of short frequency and fast speed, and effectively reduces the initial investment, it is estimated to be very useful... But it seems that the domestic use is relatively small, the editor thinks that we are slow to withstand the new materials, and because of the good equipment , The price is cheap, and there is no profit point for the installation unit...hahaha...! In any case, we should bear more things that are different. It is still somewhat helpful to the business. When we see a new thing, we don’t need to deny it first. Perhaps we are eager to find its shortcomings to show our talents. Because of this It will only constrain our creativity and development ability... Throughout the past, people who are good at enduring new things always win...! Not much nonsense... Let’s take a look: 1. The South air duct is permeable, isn’t that a leak? This air duct is mainly used in places where the air is delivered while transmitting, that is, where the air is not suspended from the ceiling in a large space. If it is used in the suspended ceiling, it is not suitable for transmission. Perhaps air-tight materials are used, but it must be in a cooling and ventilating place with low condensation requirements. 2. Your air duct is blowing while blowing air. Is there no wind behind it? The frictional resistance of this duct is small, and the resistance along the way is generally not greater than the static pressure recovery. As long as the static pressure at the inlet of the straight pipe is greater than 80Pa and the inlet wind speed is above 5-9m/s, there will be no wind at the end. 3. Can the Soth air duct have a filtering effect? This air duct is permeable and has a certain filtering effect, but it cannot replace the filter of the air conditioning unit. If the customer's environment requires, this air duct can be equipped with a special high-efficiency filter device in the fabric at its entrance to filter dust. 4. Can the Southwind pipe pass through the fire compartment? Yes, but a fire damper must be installed. The air pipe is connected to both ends of the fire damper, so that the air pipe cannot form a skewer, which meets the requirements of the fire protection code.

Many of us have heard about resistance temperature detector and seen some of these units in operation in RTD supplier, temperature sensor manufacturers and RTD supplier spaces.
