Chiller – is a refrigeration unit for air conditioning in commercial premises. Industrial chillers have a wide range of applications. They are used in the wine industry, production of plastics, mechanical engineering and metal processing, food, chemical and pharmaceutical industries for a variety of technical needs, as well as for ice rinks and swimming pools. The chillers maintain the required temperature for the productive operation of the equipment.
Chiller or industrial liquid cooler
Chiller is the industrial equipment for
cooling of a liquid which in turn cools through heat exchanging equipment
objects of conditioning or production processes. Thus, the unit performs one of
the most important functions – cooling without which the existence of most
office, residential, commercial premises and production processes is
does the chiller works?
Cold production process occurs in a closed
circuit, where involved three main nodes:
1. cooling Compressor
2. evaporator (heat exchanger)
The compressor compresses freon gas where
it is heated to 80-90 degrees and enters the condenser. Installed above the
heat exchanger fans cool the freon flow of incoming air to a temperature
slightly above outdoor air. Next the refrigerant enters the filter dryer and
after passes through the thermostatic expansion valve (TEV).
The next step is the most important, is the
transition in freon exchanger where he boils and going from liquid to gaseous
takes heat from coolant, resulting in water or glycol cooled to the temperature
and the freon is heated to the State of the couple, and then returns to the
compressor and the process is repeated.
To date, industrial chiller selection is
huge, and is chosen based on the task at hand.
Types of chillers:
1. By condenser cooling type: air and water
cooled 2. By type of execution: split system or bar
2. By noise level: standard, low noise and
super low noise.
3. By temperature mode: high temperature,
average temperatures, and low-temperature.
4. By type of compressors: screw, scroll or
5. By type of heat exchanger: plate or
6. By hydro-module type: full hydro-module,
with a pump and expansion tank, pump and cumulative capacity, with two pumps,
7. With additional features: recovery of
heat, heat pump, free cooling.
Manufacturers and brands (information
written exclusively from our experience).
Industrial chillers produce worldwide
ranging from manual garage Assembly and ending with international concerns with
the robotic assembly sites.
nevertheless, we would like to share them this way:
Chillers of American brands. Standard
TRANE is the most reliable and durable chillers. Made with high quality
materials and modern technologies. Install the spiral and screw compressor,
various types of heat exchangers, which makes it possible to use them for all
kinds of tasks from low temperatures on the ice arenas before chilling mold.
Carrieris a sweetie, and most famous brand. Just one title that it wanted
to acquire, stylish design and modern technology often use heat recovery and
heat pumps, as well as their production Rotary screw compressors. Pro control
system-dialog with the touchpad makes management easier and faster. Carrier is
most often used for air conditioning of buildings.
York - excellent machines, the leaders of the field of manufacture of
refrigerating machines. Manufacturing them for the European market in the
UK. Are based on the screw and scroll
compressors. Suitable for use in low temperatures.
Lennox is a little less common chiller from the American brand. In Europe
appeared after the merger with the Dutch brand REFAG. However, the excellent
quality, often produces small models with scroll compressors installed. Often
protected from aggressive sea air condenser.
Chillers produced in Germany and
Riedel- the company specializes in production of machines
for cooling molds in the manufacture of plastic products as well as cooling
laser metal cutting. Equipped with
scroll compressors, and hydro module with a pump.
OPK- rarely used technique, however, like all German is not deprived of
attention to detail. Chiller is made on the basis of scroll compressors,
equipped with additional sound-insulated heating by irradiation in cold period
of time, and other things that help in its operation.
Ciat - chiller from the French manufacturer. Durable and easy to
operate, up to the year 2000 were painted in blue and assembled piston
compressors. And now this machine based on the scroll Copeland compressors that
use energy-saving technologies.
Chillers produced inItaly.
Climaveneta - who does not know this brand in Ukraine. Sample of the perfect
Italian chiller. Often the covering is made of stainless steel, it looks very
impressive. In addition, Italians are keen to be the first in the field of
energy saving by releasing a new generation of models IFX with inverter
Geoclima - little known company in Ukraine, but it should be noted that the
quality of these cooling units is always on top. Use of quality metal and
first-class European components in the manufacture of the chiller, makes these
machines stable robot and has no impact of weather conditions.
