2. A system of process for
controlling the lowering
the temperature dan
humidity of an enclosed
space.

3. COMPRESSOR
Inhaling the refrigerant
from the suction channel
- Compressing to the
discharge channel.
Hot refrigerant vapor
and high pressure
CONDENSOR
Remove heat from
condenser
Refrigerant vapor
turn to liquid.

5. Window Air-conditioning
System
 Window air-conditioner
units are a reliable
 Simple to install solution
 Easily removed for storage
Split Air-conditioning
System
• The outdoor unit and the
indoor unit.
 Durable
 Simple to install

6. Package Air-conditioning
System
 Used for the cooling capacities
in between these two
extremes.
 The packaged air conditioners
fixed rated capacities of 3, 5, 7,
10 and 15 tons.
 Used commonly in places like
restaurants, telephone
exchanges, homes, small halls.
Low Statics
Fan Coil
• One or more heat exchangers
• One or more fans with electric
motors
• An appropriate enclosure,
• Condensed water collecting
facilities when cooling

7. Set Tool
Refrigerant Gas
Manifold Gauge

8. Vacuum Pump
Chemical

9. Refrigerant leaks can happen
with vibration of the unit while it
is operating.
Dirty A/C units wont operate at
peak efficiency. (Coil Condensor)

10.  One possible reason that HVAC
systems blow warm air is dirty
filters.
Frozen coils are causes
circulation problems.
