Air-conditioning systems are designed to control and maintain indoor air temperature, humidity, and air quality in
buildings or vehicles. They create a comfortable environment by cooling the air in hot weather and sometimes heating
it in cold weather. The basic components of an air-conditioning system include a compressor, condenser, evaporator,
and expansion valve. The process begins with the compressor, which pressurizes the refrigerant gas. The high-
pressure gas then passes through the condenser where it releases heat and turns into a high-pressure liquid. Next, the
liquid refrigerant flows through the expansion valve, which reduces its pressure, causing it to evaporate and turn into a
low-pressure gas. During this evaporation process, heat is absorbed from the surrounding air, thus cooling it. The
cooled air is then circulated throughout the space using fans. This cycle continues until the desired indoor temperature
is achieved. Modern air-conditioning systems often include additional features such as air filters to improve air quality,
programmable thermostats for energy efficiency, and zoning to control temperature in different areas separately.The
air conditioning system is a technology designed to control and regulate the temperature, humidity, and air quality
within indoor spaces. It typically involves a combination of equipment such as compressors, condensers, evaporators,
and fans to circulate and cool the air. Air conditioning is commonly used in homes, offices, vehicles, and various other
buildings to provide comfort and improve air quality.
3. IN 1902, CARRIER DEVISED A BREAKTHROUGH SOLUTION TO THE
PROBLEM OF CONTROLLING TEMPERATURE AND HUMIDITY IN AN
INDUSTRIAL SETTING. HIS INVENTION, KNOWN AS THE "APPARATUS
FOR TREATING AIR," USED A PROCESS CALLED "RATIONAL
PSYCHROMETRIC" TO CONTROL THE MOISTURE CONTENT IN THE
AIR. BY CONTROLLING HUMIDITY, CARRIER'S SYSTEM COULD NOT
ONLY LOWER THE TEMPERATURE BUT ALSO IMPROVE THE OVERALL
AIR QUALITY AND COMFORT.
