AC SYSTEM TYPES
Nowadays, different varieties of AC systems are installed in 
residences and workplaces. The four primary types of air 
conditioning systems used in places such as Dubai, Abu Dhabi, 
and Al-Ain are:
1. Split-system air conditioning (i.e. DX System)
2. System for Chilled Water (Chillers or District Cooling)
3. Packaged Air Conditioning System
4. VRF (Variable Rate Frequency) System
Split AC (DX System)
● Split air conditioning (DX systems) is prevalent in villas, 
townhouses, and low-rise apartment buildings. 
● It is referred to as a split system since it has both an interior 
and exterior unit. 
● Each interior unit is connected to its corresponding outdoor 
unit. The outside unit is primarily responsible for cooling, 
while the indoor unit distributes cold air to the air outlets 
via duct distribution. 
● The cooling effect is accomplished by refrigerant gas passing 
through copper pipes between the indoor and outdoor units.
Chilled Water AC System
● High-rise structures and some villa development projects 
typically use chilled water (district cooling cost savings) 
systems. 
● This system includes interior units, where all interior units 
are connected to a central cooling plant via a pipe network. 
● The cooling plant produces the majority of the cooling, while 
the indoor unit distributes the cold air to the air outlets via 
duct distribution. 
● Chilled water is circulated between the cooling plants and 
the indoor units to provide cooling.
Package AC System
● Package air conditioners are most typically used in buildings 
with huge areas that need to be cooled, such as warehouses, 
tiny shopping malls, and schools. 
● The cooling fundamentals of a package AC system resemble 
a split AC (DX System), with the exception that all 
components are contained in a single container (package).
VRF System
● The VRF system is a modernised split air conditioning 
system (DX System) that is typically found in villas, schools, 
and low-rise structures. 
● The fundamental difference between a Split AC (DX System) 
and a VRF system is that a Split AC (DX System) connects 
one exterior unit to numerous interior units, resulting in a 
more efficient system and cheaper electricity expenses.
UNDERSTAND THE AC PROBLEM AT 
HAND
There are four types of air conditioning difficulties that might 
occur in your house or office. If you encounter any of these 
problems please seek the help of an AC service provider. 
● The air conditioner isn't working properly.
