AIR CONDITIONING SYSTEMS

IN BUILDINGS

• UNITARY SYSTEM

• SPLIT – TYPE SYSTEM

• CENTRALIZED SYSTEM

Air conditioning – is the process of treating air so

as to control simultaneously its

1. Temperature

2. Humidity

3. Cleanliness and

4. Distribution

to meet the requirements of the conditioned

space.

transports the refrigerant

at the required pressure through the air

conditioning system.

• COMPRESSOR

• CONDENSER

• FILTER DRIER

• EVAPORATOR

Answer explanation

works in the opposite way to the Evaporator.

The refrigerant gives up its heat generated by the Compressor by

passing cold air across its fins and tubes by ram air or by an extra fan.

The end result of this change is that the refrigerant is now a high

pressure liquid and is forced out to the Receiver Drier through the

liquid line

• COMPRESSOR

• CONDENSER

• EVAPORATOR

• EXPANSION DEVICE

Answer explanation

this item can be called a Receiver Drier or an

Accumulator.

is responsible for removing moisture from

the air conditioning system by means of a bag of

desiccant which absorbs small quantities of

moisture.

• COMPRESSOR

• CONDENSER

• FILTER DRIER

• EXPANSION DEVICE
