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.

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.
