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.

The installation of metal air ducts is consist of several parts: hangers, ducts, and valves.

The expanding HVAC industry has led to the invention of many kinds of new duct systems. Pre –insulated ducts have made it possible for people to enjoy the comfort of the thermal system.
