Air Conditioning: How it Works & Different Types of ACs

The term 'Air conditioning' refers to any process that changes the condition of air such as heating, cooling, ventilation, refrigeration etc. Air conditioners or ACs are designed to change the humidity and temperature as desired within an area. Air conditioners removes the warm air from a certain area and cycles it back after cooling it. What is actually happening inside the air conditioner is the evaporation of a refrigerant which results in cooling.

In this guide you will find articles related to the air conditioning processes and different types of air conditioning systems. You will also find information about air conditioning alternatives and new cooling technologies which are being designed and implemented.
