Introduction
• Air conditioning often abbreviated as AC, is the process of
removing heat and controlling the humidity of air in an
enclosed space to achieve a more comfortable interior
environment by use of powered "air conditioners" or a variety
of other methods, including passive colling and ventilative
colling. Air conditioning is a member of a family of systems
and techniques that provide heating, ventilation, and air
conditioning.
• Air condition make life Comfortable.
• The main purpose of installing an air conditioning unit is to
get the cooling effect. 7

What Is AC?
An air conditioner provides cold air inside
your home or enclosed space by actually
removing heat and humidity from the indoor
air. It returns the cooled air to the indoor
space, and transfers the unwanted heat and
humidity outside.
The importance of
waste water reuse
generation from air
condition
Treatment of waste water or recycling of water
for reusing of different beneficial purposes like
drinking, irrigation, toilet flushing, and
industrial processes saves water resources. It
also offers economic savings. The main
purpose of installing an air conditioning unit is
to get the cooling effect. Water is produced
from air conditioners, with no cost as a by-
product which is usually unused in
Bangladesh.
