The six primary inert gases found in air are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). These gases are used in various applications to prevent unwanted chemical reactions, such as oxidation and hydrolysis, which can degrade samples or materials.

Most air conditioning systems have copper tubes inside. The oxygen going through these tends to form copper oxide in their surface. You can easily check the effect of this by taking a look at the tubes of your air conditioning system: you will probably see a dark brown discoloration. The real problem is, though, that inside the tube oxide flakes ar...
No matter what type of AC unit you choose to install, over time oxidisation will occur and your system will inevitably become contaminated. However, there is a remedy to this, as you can make sure the system gets thoroughly cleaned by using nitrogen gasto purge it. In the past, other gases were used to carry out this procedure, such as freon. Howev...
The most important thing to consider before injecting nitrogen into your air conditioning system is to be adequately protected to do the job safely. Before starting any work, be sure that you are wearing safety shoes, gloves and goggles. Once you are ready, prepare the nitrogen cylinder and its pressure regulator. Use the nitrogen to push some of t...
R22 is a refrigerant gas (HCFC) commonly used in air conditioning appliances. Since 2015, HCFCs have been illegal for servicing and maintenance, therefore many air conditioners have to be replaced or altered in order to stay compliant.
A refrigerant is a working fluid used in cooling, heating or reverse cooling and heating of air conditioning systems and heat pumps where they undergo a repeated phase transition from a liquid to a gas and back again.
Before we can examine the inner workings of direct expansion cooling systems, it will help to have a basic understanding of how fluids and gasses behave under different conditions. Specifically we are concerned with how changes in pressure, temperature or volume will affect our cooling systems.
Direct carbon emissions take into account the impact of refrigerants if leaked to atmosphere, and indirect carbon emissions take into account energy use associated with running refrigerating equipment. Getting the design right in the first place will reduce. An example of good practice in pipework.

Which noble gases are considered inert gases?
How is inert gas produced?
Purified argon gas is the most commonly used inert gas due to its high natural abundance (78.3% N 2, 1% Ar in air) [3] and low relative cost. Unlike noble gases , an inert gas is not necessarily elemental and is often a compound gas.
