General AC Information

In general, the understanding of AC (Air Conditioner) a series of machines that have the function of air conditioning around the cooling machine.

Specifically the understanding of AC (Air Conditioner) is a machine that is used to cool the air by circulating refrigerant gas in the pipe which is compressed and suction by the compressor.

The reason why refrigerant gas is chosen as a circulating material, because this material is volatile and its shape can change, in the form of liquid and gas. The heat in the condenser pipe comes from the refrigerant gas which is compressed by the compressor so that the material becomes hot and in the Automatic Expantion Valve the pipe where the refrigerant gas circulation is reduced, so that the pressure increases and the evaporator pipe cools.

We will explain how to decode the model number, especially in AC split which is most often used in malls, schools, offices, companies, etc.

Both industrial refrigeration and air-conditioning are based on the same mechanism: a fluid, generally water or air, is cooled by evaporation of another fluid, called the refrigerant. The refrigerant routine, including the air compressor, evaporator, condenser and enlargement gadget, is certainly an essential component of both systems. non-etheless, there are significant distinctions between refrigeration and air-conditioning systems, for example as relation the elements, the style strategies, the industrial or commercial buildings where they're set up and their procedure, such as to justify the lifetime of two specific marketplace areas.

Air-conditioning is that procedure used to create and maintain specific temperatures, essential contraindications humidity and air flow purity conditions in indoor spaces. This process can be typically applied to maintain a level of personal comfort and ease.

It's also used in industrial applications to ensure correct operation of gear or machinery that need to operate in specific environmental conditions or alternatively to be able to carry out certain industrial processes, such as welding, which produce considerable amounts of warmth that needs to be disposed of in some manner.

An air-conditioning system must be effective regardless of outside climatic conditions and involves control over four fundamental variables: air flow temperature, humidity, movement and quality.

The distinction between industrial and personal comfort applications is not always clear cut. Industrial air-conditioning usually requires better precision as regards heat and humidity control. Some application also demand a high degree of filtering and removal of contaminants.

Comfort and ease air-conditioning on the other hand, as well seeing that needing to fulfill personal temperature-humidity requirements, also involves various other areas such seeing that architectural style, weather conditions forecasting, energy intake and audio emissions to recreate the ideal circumstances for individual psychophysiological well-being.

The primary process underlying air-conditioning is the exchange of heat and water vapour between the indoor and outdoor environments and the most people in the air-conditioned space.

What is Air Conditioning?

The first functional definition of air-conditioning was created in 1908 and is credited to G. B. Wilson. It is the definition that Willis Carrier, the “father of air conditioning” subscribed to:

  • Maintain suitable humidity in all parts of a building
  • Free the air from excessive humidity during certain seasons
  • Supply a constant and adequate supply of ventilation
  • Efficiently remove from the air micro-organisms, dust, soot, and other foreign bodies
  • Efficiently cool room air during certain seasons
  • Heat or help heat the rooms in winter
  • An apparatus that is not cost-prohibitive in purchase or maintenance 


The job of your home air conditioner is move heat from inside your home to the outside, thereby cooling you and your home.

Air conditioners blow cool air into your home by pulling the heat out of that air. The air is cooled by blowing it over a set of cold pipes called an evaporator coil. This works just like the cooling that happens when water evaporates from your skin. The evaporator coil is filled with a special liquid called a refrigerant, which changes from a liquid to a gas as it absorbs heat from the air.

The refrigerant is pumped outside the house to another coil where it gives up its heat and changes back into a liquid. This outside coil is called the condenser because the refrigerant is condensing from a gas back to a fluid just like moisture on a cold window.

A pump, called a compressor, is used to move the refrigerant between the two coils and to change the pressure of the refrigerant so that all the refrigerant evaporates or condenses in the appropriate coils.

The energy to do all of this is used by the motor that runs the compressor. The entire system will normally give about three times the cooling energy that the compressor uses.

This odd fact happens because the changing of refrigerant from a liquid to a gas and back again lets the system move much more energy than the compressor uses.
