Air Conditioning System!...Feel Cool Everywhere!!!

Air conditioning (often referred to as air-con, AC or A/C) is the process of altering the properties of air (primarily temperature and humidity) to more favorable conditions. 

Parts :-

Evaporator - Receives the liquid refrigerant
Condenser - Facilitates heat transfer
Expansion valve - regulates refrigerant flow into the evaporator
Compressor - A pump that pressurizes refrigerant

& there is a Fan 

How it works :-

Air conditioners use refrigeration to chill indoor air, taking advantage of a remarkable physical law: When a liquid converts to a gas (in a process called phase conversion), it absorbs heat.
The compounds involved are refrigerants that have properties enabling them to change at relatively low temperatures. Air conditioners also contain fans that move warm interior air over these cold, refrigerant-filled coils. In fact, central air conditioners have a whole system of ducts designed to funnel air to and from these serpentine, air-chilling coils.

When hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. To keep cooling efficiently, the air conditioner has to convert the refrigerant gas back to a liquid again. To do that, a compressor puts the gas under high pressure, a process that creates unwanted heat. All the extra heat created by compressing the gas is then evacuated to the outdoors with the help of a second set of coils called condenser coils, and a second fan. As the gas cools, it changes back to a liquid, and the process starts all over again. 

The Role Of ICT In This System :-
The use of sensors that compare the temperature requested and room temperature to control the switching on and off of the cooling system.
