is the simultaneous control of temperature, humidity, motion, and purity of air to
attain the requirements of a confined space.
AIR CONDITIONING
if the desired temperature of space is higher than the surrounding
temperature and applicable during winter
heating
if the desired temperature of the space is lower than
its surrounding temperature and applicable during summer
cooling

Engineers.
is the process of treating air so as to control simultaneously its temperature,
humidity, cleanliness, and distribution to meet the requirements of the
conditioned space.
AIR CONDITIONING
An air conditioning for providing at least a partial measure of comfort for workers in hostile environments and also for maintaining the required conditions of material processing.
Industrial Air Conditioning
Providing comfort for the occupants of residential houses
Residential Air Conditioning
Providing comfort for the occupants of commercial buildings such as department stores, theaters, hospitals, offices, motels, hotels, and others.
Air Conditioning of Commercial Buildings.
Providing comfort for the passengers of vehicles such as buses, cars, trains, aircrafts, and others.
Air Conditioning of Vehicles
MAJOR PARTS OF AIR CONDITIONING
SYSTEM
A. COMPRESSOR
B. Evaporator
C. Condenser
D. Expansion Valve
E. Refrigerant
More commonly known as Freon
REFRIGERANT
is the
liquid or gas which is passes through all
the other components in the air
conditioning system.
REFRIGERANT
This cooling liquid is moved throughout
the system by the compressor found in the
outer half of the air conditioning unit.
REFRIGERANT
the heart of air conditioning unit.
COMPRESSOR
Compresses the refrigerant from a low
temperature, low pressure gas to a high
temperature, high-pressure gas.
COMPRESSOR
Pressure raising devices.
COMPRESSOR
In a literal process of compression, the
compressor sends refrigerant to the
condensing coil in the form of high
pressure gas,
COMPRESSOR
This is where the refrigerant evaporates
from a liquid form back into gaseous form.
EVAPORATOR
When the refrigerant evaporates in the
evaporator, it absorbs heat from the
surrounding air and produces cooled air.
EVAPORATOR
Low-pressure vapor heat exchangers.
EVAPORATOR
This component receives gas at high
pressure and high temperature from the
compressor.
CONDENSER
High- pressure vapor heat exchangers.
CONDENSER
a narrowing of the tube connected along
the line between the condenser and the
evaporator.
EXPANSION VALVES / CAPILLARIES
Throttling devices that transport the
refrigerant from high-pressure condition
(condenser) to low-pressure condition
(evaporator).
