The document discusses air cooled chillers used for commercial and industrial cooling. It describes how air cooled chillers work using a closed refrigeration cycle of evaporation and condensation to lower the temperature of surrounding air. The chiller system includes an evaporator, compressor, and condenser connected in a loop. Chilled water is circulated to absorb heat from the area being cooled before returning to the evaporator. Manufacturers specialize in chillers for different industries and applications like process cooling. Proper selection requires consulting engineers, comparing quotes, and ensuring good after-sales support.

1. Air Cooled Chillers In Air Conditioning And Refrigeration
To work optimally human beings require a comfortable environment. Needless to
say the temperature must be ideal, not too hot nor too cold. Hot weather makes a
person sweat and irritable. To tide over this problem, deliver comfort and increase
worker productivity, air conditionersare used extensively in offices, hospitals and
commercial buildings. For some industries and research facilities cooling is a critical
requirement.
A rugged machine which promises optimum cooling is needed in homes and
commercialestablishments and in recreation centers like malls and cinemas.
Chillersare the devices which produce the low temperatures and pleasant feeling
when we step into a mall from the hot exterior.
Chillers achieve the cooling and aredesigned to suit differentpurposes. They maybe
water cooled and air cooled screw chillers, water cooled and air cooled scroll
chillers, MRI chillers and Ammonia screw chillers.
Air cooled chillers employ a cycle of evaporation and condensation processes
insidea closed system to reduce the temperature ofthe air around. These are more
efficient than Freon-based chillers used in refrigerators. The evaporator consists of
a frame of tubes around a chamber which is connected to a compressor. The
compressor joins a condenser which in-turn is connected to the evaporator. Air
cooled chiller does not mean water is not used at all. Actually water is not employed
to absorb waste heat but used otherwise.
The liquid refrigerant in evaporator chamber makes water in surrounding tubes cold
by radiation. This chilled water passes via circuit to be cooled and absorbs heat
making the region around it cold. When the water becomes hot it radiates heat to
the refrigerant inevaporator and vaporizes it. This vapour on passing through
compressor is subjected to high pressure and heat which is then sent to condenser.
This has a series of air-cooled vanes where heat is given off to surrounding air. The
vapour liquefies here and goes back to evaporator to continue the chilling process.
Many air cooled chiller manufacturers specialize in making chillers for specific
industries like plastics and pharmaceuticals and so on. Robust chillers are
imperativein deep freeze store houses which refrigerate meat, fruits and vegetables
besides in central cooling of huge malls and office buildings.
Residential buildings, high rises and hugevillaswith central air-conditioning facilities
require air cooled chillers specially designed for the purpose. Manufacturers deliver
value throughcomfort cooling or providing process cooling solutions to industries.
2. Chillers For Commercial And Industrial Use
When looking for chillers for Industrial or Commercial use, you need to be
extremely careful during your search. When being used for Industrial
applications, you need to ensure that you have the correct specifications
with you so that you can make the right decision. It is important that you
first consult with an engineer on site,
Since there is so much information available online and the competition is
stiff as well, you have to be careful about whom you trust and whom you

2. should not. The process for finding a reliable and trustworthy chiller
manufacturer can be tough if you go about it in the wrong way.
Start by looking for a list of suppliers and manufacturers online. When you
do have a list, go through all the information that you have before you, or
even look for more information online, until you are able to make a short
list of about 4 to 5 vendors that can provide you with what you are looking
for.
Once you have this list in front of you, you could either call them up, or you
could simply send them an email with your requirements. Soon, you should
have a few comparative quotes in your in box and before you, so that you
can make the right choice.
Go through the quotes thoroughly. Get your engineer involved and take
your pick depending on which manufacturer provides you utmost value for
money. Make sure to check the after sales service policy, as you want a
good after sales service in place to ensure that you do not face much
trouble if something were to go wrong with the chiller.
The process is indeed simple, and when you do follow this approach for
finding chillers to the tee, you can be rest assured that you will have no
complaints once the equipment does arrive at your doorstep, waiting to be
installed. Do not worry about the time investment, as it is only going to
help you reap profits in the long run. Spend some time now, and you will
save a lot of effort and money.
The competition is tough, and you have to choose carefully, remember the
tips above and you will be able to make the right call with regards to the
best chiller in the market for your needs.
Are You In The Market For A Water Cooled Screw Chiller?
Today, a Water Cooled Screw Chiller is used for a number of applications in
varieties of industries. If you are currently looking for Water Cooled Screw
Chiller, but are unaware about how to go about the process, read on to
learn how you can make a good decision.
What you must know before you start your search is that there are a
