The panel duct or pre-insulated aluminum duct has been on the world market for almost fifty years, but until recently the construction of rigid ducts for air conditioning was mainly directed to fiberglass and galvanized iron sheet. commonly called HG, it can be said that in the last decade the pre-insulated aluminum duct has replaced almost one hundred percent of these materials and in this article we will see why.

1.Strengthen the design of various pipeline lines before installation
In an HVAC system, there are many plumbing lines. Their various management functions are different, and they all have their own unique missions. Therefore, they should be staggered as much as possible when designing to reduce mutual interference.

In the installation construction of air system, there are a lot of aspects need to be paid attention to, otherwise bad effects later in using may occur. Among all the construction processes, the handling of water circulating and water condensation is essential. If not handled appropriately, the whole air conditioning operation will just have constant problems and leave customers a terrible experience and impression. Hope you find this article useful for your construction.

A ductless air conditioning system doesn’t come with ducts in the walls for air distribution. A ductless air conditioning system sends refrigerant directly to multiple small air handlers (also called blowers) that are installed throughout your residence.

Have you ever understood the air duct classification and system composition? This article will introduce you to all the relevant knowledge. Come and learn with VENTECH!

Phenolic insulation materials consist of solids mixed with phenolic resin and a a surface acting agent. The resulting reaction produces a network of bubbles, then the bubbles will be cured into a foam.

In the heating, Ventilation and Air Conditioning (HVAC) system, air ducting is playing an important role. Several factors and recent innovation have introduced the need to revolutionize air ducting. The pre-insulated system is a proven, easy, innovative product.

With the development of the times, traditional building decoration no longer meets people's needs. In construction projects, the installation of HVAC has become an important measure for current building warmth and ventilation.

1.Equipment installation
The installation of fresh air systems and air conditioning units should use spring damping dampers; fan and air duct connection should use soft connection; fresh air units and water pipes should use soft joint connection; fan coils should use spring hooks; fan coils and water pipes should use hose connection.

With the rapid development of our country's national economy, air-conditioning technology has been widely used. According to statistics, the current energy consumption of HVAC accounts for 25% to 45% of the total energy consumption of buildings, and it is increasing at a large rate every year.

The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. The principle of liquid vaporization refrigeration is adopted to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment;

We heard AHU, HRV, FU, etc. often in the Heating Ventilation and Air Conditioning industry. So, what are these words means? Now let’s explain to you.
