Which gas is used in AC

Air conditioner is the process of removing moisture and cooling the air in a closed environment. They are commonly used in residential and commercial buildings. It is also used to cool and dehumidify rooms where electronic devices are located, such as computer server rooms. In this article, we want to know in ac which gas is used.
 

Let’s find out which gas used in AC over the years.

  • Chlorofluorocarbons (CFCs): The most common refrigerant in the past was a CFC, most commonly called as Freon. Freon was a brand name for a refrigerant “R-12” by Dupont. The manufacturing of CFCs was discontinued in 1994 as the CFCs are one of the main reasons for greenhouse gas effect and depletion of ozone layer. read more

 

he mechanical draft system is a drainage system to remove flue gases through mechanical devices such as a fan.

Mechanical draft cooling towers are the most widely used in buildings which rely on power-driven fans to draw or force the air through the tower. In other words, air is circulated inside the tower mechanically by use of propeller fans or centrifugal fans. They are normally located outside the building. Mechanical draft towers come with a compact design and are powerful and variably adaptable to the respective operating and climatic conditions. Furthermore, they are the ideal solution for industrial applications such as in power plants, chemical and petrochemical plants, steel plants, air separation plants, in the automotive industry, in timber and paper factories as well as in air conditioning/ refrigeration systems. The two most common types of mechanical draft towers are induced draft and forced draft.
