When you’re up to install or replace a
centralized air conditioning system it means you have to compromise with your
biggest expenses. And that is the reason you want installation or replacement
of the Air Conditioning System to be done right the first time. But when it
comes to visualizing in real life, it is not practically possible that consumer
gets a perfect replacement at a single effort. So many variables lay a direct
or indirect effect on the successful implementation of the Centralized Air Conditioning System within the premises. The
variables like size and design of premises, way of system installation and
construction of ductwork, etc.are some direct means to affect the installation
process.
The latest survey conducted on more than
twenty thousand users of the centralized air conditioning system installed by
them reveals some major points. The report describes which parts break and what
does it cost to fix central AC at the time where repairing is required.
By the way, the segment of
air-conditioning and refrigeration is having a very vast application with
diverse application requirements. Some important terms related to airconditioning systems are:
Unit
The unit of refrigeration is a ton, which
is a time rate of cooling equal to 12000 BTU/Hr.
Refrigeration
cycle
The major components of the vapor
compression cycle are a condenser, thermostatic expansion valve, and
evaporator. The refrigerated gas enters into the compression at low temperature
and low pressure where it is compressed by leaving compressor at high
temperature & pressure.
Equipment
used in Centralized Air Conditioning System
1-Compressor-
Sealed, semi-sealed and open type
2-
Condenser
Generally, the condenser is made
available in two types of design- Water cooled type design or air-cooled type
design. Water-cooled type condensers are in the form of tube or shell
construction, whereas air-cooled condensers are an assembly of finned tubes
through which refrigerant flows & rejects air heat.
3-Evaporator
When the medium of cooling is air, the
evaporator type is called a direct expansion cooling coil that comes along with
finned construction. In this system, air flows over the tubes and the refrigerant
flows through the tubes. When the medium is water, the evaporator is called
direct expansion chiller
4-Cooling
coil
There are two types of cooling coils
direct expansion or chilled water type. The cooling coil has finned tube
construction where refrigerant gas or chilled water moves via tubes & air
is driven over the tube surfaces. Fins are specially used to increase the
effective heat transfer area. Once the refrigerant flows via tubes, the cooling
coil is converted as a direct expansion cooling coil.
5.
Air Handling Unit
Air handling units have a cabinet type
sectionalized construction specially used in air conditioning applications. It
is connected with other equipment in the refrigeration circuit through the
cooling coil.
Apart from these five major units, other
auxiliary equipment like a cooling tower, pump sets, ducting, piping,
insulation work, etc., are required for completing the installation of the Air
Conditioning plants. For the installation of central plants, there is the
requirement of two separate areas-Condensing
unit and Chilling Unit.
To keep the Air conditioning system
working properly for a long time four tips should be followed by the users:
● Keep it clean
● Seal and insulate
ducts
● Seasonal checks
I hope, an overview of the Centralized Air Conditioning System is
