We all know that many people in the modern home are using central air conditioning, and the main type of central air conditioning contains a kind of air duct central air conditioning, it is through the air conditioning ventilation pipe to discharge heat treatment, so when we buy central air conditioning, whether we also want to have a certain understanding of the ventilation pipe? The answer is yes. Let’s take a look at the types of air conditioning ventilation ducts.

What is an air conditioning ventilator

Wind pipe machine is a new type in recent years. Due to the consideration of aesthetic and economic factors, wind pipe machine is also used in ordinary families. At present, most users use 1 drag 1 air duct machine (that is, an outdoor host + an indoor machine), this kind of air conditioning solves the hanging machine, cabinet machine exposed to the outside influence beautiful problems, at the same time, its pipe length is longer than ordinary household air conditioning, installation is more flexible, customers can choose to install one or more according to the actual needs.

Through reasonable design of air and return air, can maximize the use of comfort. Compared with ordinary air conditioning, air supply by air duct machine is more healthy and scientific, and there will be no discomfort caused by direct blowing of traditional air conditioning; And in the same space, the temperature difference of the air duct machine can be accurately controlled at ±1℃, which is not easy to cause “air conditioning disease”.

Types of air conditioning ventilation ducts

(1) Galvanized steel pipe: mechanical bite, Angle steel flange connection, outsourcing insulation layer and moisture-proof layer. It is one of the earliest used air duct materials. It has the advantages of high mechanical strength, moisture resistance and water resistance, dust resistance and sound insulation performance, but the production and installation cycle is relatively long and the labor intensity is high.

(2) Inorganic FRP air duct: hand-made, flanged, with single-layer FRP air duct external insulation layer and composite FRP air duct (double-layer FRP internal insulation layer) in two forms. It is a relatively new air duct material in recent decades. It is made of glass fiber reinforced inorganic material, which has the advantages of corrosion resistance, high temperature resistance, high hardness, flame retardant and sound insulation performance. However, it is easy to distort and deform due to the influence of processing and self-weight, and the production and installation cycle is long and the labor intensity is high.

(3) Composite aluminum foil glass fiber air duct (also known as super air duct) : there are two forms of field cutting, split-flange connection and heat-sensitive aluminum foil tape connection. The air duct has thermal insulation performance, no need to separate thermal insulation.

Introduction to the principle of air duct type central air conditioning

Air duct type small central air conditioning, also known as pipe type small central air conditioning, composed of outdoor and indoor units, divided into two types of single cooling and heat pump type. It is based on air as the conveying medium, the principle of which is basically the same as that of large all-air central air-conditioning system. The outdoor host is used to generate cold/heat, and the return air (or the mixed air of return air and fresh air) from the indoor is cooled or heated, and then sent into the indoor. Because of the fresh air mixed into the room, indoor temperature, humidity and cleanliness can be controlled at a higher level. This kind of central air conditioning adopts the following new technology:

(1) The compressor adopts overload protection, and the indoor and outdoor machines adopt unique muffler device, which can fully reduce the vibration and noise.

(2) Using low temperature control system, the outdoor unit can work normally when the outdoor temperature is below -18 ℃. When the outdoor heat pump defrosts, it can still supply hot air continuously.

(3) Adopt a unique microcomputer control system, so that the unit can be randomly set the temperature of four periods of a day in a week, can also change and adjust the temperature setting according to the need.

The above is the relevant introduction of the types of air conditioning ventilation ducts. After reading the above introduction, whether you have a more profound understanding of the types of central air conditioning and air conditioning ventilation ducts? I hope the above introduction can help you better use central air conditioning.
