When you hold the phenolic insulation board, you will find it is light and easy to transport. Phenolic insulation board is a closed-cell rigid foam plastic made by scientific formula with phenolic resin and flame retardant, smoke suppressant, curing agent, foaming agent, and other auxiliaries.

In the past few years, we’ve collected opinions from more than 100 customers in duct fabrication business. Some of them are still using hand cutting, some of them are using machines to cut.

1. Comparison of traditional air ducts and phenolic air ducts
The traditional air supply pipes of central air conditioners are usually made of iron sheet or glass fiber reinforced plastics on the inner layer, wrapped with thermal insulation materials, and wrapped with aluminum foil on the outermost side, which makes the air supply pipes heavy and large, time-consuming for construction and installation, poor appearance, low air tightness, and energy-saving.

The water-cooled chiller belongs to the refrigeration unit part of the central air-conditioning system. Its carrier refrigerant is water, which is called a chiller, and the cooling of the condenser is realized by using the heat exchange and cooling of normal temperature water.

If we can't escape the heat, the best way is to cool off in the best way possible, isn't it? However, care is needed at these times. Getting sick in the heat is a very bad and unpleasant experience.

1. The side length of the rectangular duct made of phenolic aluminum foil composite duct should be 120≦L≦3000, and the ratio of the long side to the short side should not be greater than 4:1.
When making the air duct, in order to ensure the strength of the air duct after it is made, one side of the adhesive part should be kept with 20mm aluminum foil for edge protection during cutting.

Have you ever heard that using proper insulating materials in your building can cut your energy bills in half? The key is to boost the efficiency of your heating and cooling activity by adding insulation, no matter it’s a home, warehouse, or a office building.

Compressor valves are usually round and include a series of discs between the valve seat and the valve cover. Whenever the pressure changes, the disc is pushed to the high pressure area, and when the pressure drops to the normal range, the disc returns to its position under the action of the spring.

The best place to locate the duct system for homes with ducted heating and cooling systems is within the conditioned space of the home, either in dropped ceilings, or between floors, or in a sealed and insulated basement, crawlspace, or attic. When HVAC ducts are installed in a vented attic in a dry climate, bury the ducts in attic insulation to protect them from temperature extremes in the unconditioned attic space.

HVAC duct works require many different tools and equipment to make all kinds of shapes and fittings. Using the right tools and equipment can save you a lot of trouble. Hence, it’s necessary to choose the right machines for your work. Here we’re introducing some of the duct fabrication machines for galvanized ducts and pre-inslulated ducts.

Smart thermostats are mainly used in heating, ventilation and air conditioning equipment or systems to control the temperature in a room or area. Smart thermostats allow customers to automatically and intelligently adjust settings to achieve energy savings and interconnect with equipment or systems outside of the HVAC system.

The Brazilian market, with regard to pipelines, is extremely diversified. There are conventional ducts, of the galvanized steel (GI duct) sheet type, coated with thermal insulation or not, depending on the application.
