Can cooling towers are chillers work together
                          Can cooling towers are chillers work together?
Cooling towers and chillers come in handy for serving the commercial zones. 
They take care of similar purposes and are used to cool industrial processes like 
food processing units, metal plating, etc. The cooling towers reject the waste 
heat in the atmosphere using a coolant stream, while the chiller gets rid of the 
heat from the liquid coolant via refrigeration, vapour compression, and 
absorption refrigeration cycle. Both machines have different modes of operation. 
For those interested in knowing more about the cooling towers and chillers, more 
information is provided in the following sections. Please have a look!
How does a cooling tower work?
A cooling tower offers cold water to get rid of the heat from the coolant used to 
control the equipment's temperature, process fluids, and buildings. When this water 
comes in contact with the air, a small quantity evaporates, and the temperature 
decreases. This process is called evaporative cooling. 
In industries, the heated water from the industrial process enters the heat exchanger 
or condenser. Then, it flows through the pipework and goes to the cooling tower to 
extract heat. Or else the water directly flows to the tower. Next, the tower featuring 
the spray nozzles disperses liquid on fill material. Because of the large surface area, 
more water comes in contact with the air, which increases the rate of evaporation. 
During the process, the fans aid the cooling process, and the drift eliminators get rid 
of the tiny water droplets produced during evaporation.
Cooling Tower Applications
Mainly, cooling towers are used in large-scale cooling operations like power 
generation and oil and gas refining. One important factor you need to consider 
when deciding between a cooling tower and a chiller is the required coolant 
temperature. The tower temperature depends upon the wet-bulb condition and 
the ambient air temperature. 
How do industrial chillers work?
The equipment is responsible for eliminating heat from hot gaseous coolant 
produced during the process. Then, it is transferred to the refrigerant. Later, the 
used refrigerant is cooled and regenerated using ambient air or water and 
returned for recirculation. Depending upon the medium used for dissipating 
heat, the chillers are primarily of two types, the air-cooled chillers that expose 
the heated coolant to the ambient temperature to control the temperature, and 
the water-cooled chiller offers water and coolant to condense the coolant.
How can cooling towers and chillers work together?
The cooling towers and chillers differ based on the mode of operation. They can 
be used independently or in combination for large-scale cooling. It depends upon 
factors like the required volume of cooling, available space, access to water, and 
budget. 
For small scale cooling, you can get a suitably-sized air-cooled/water-cooled 
chiller and a portable cooling tower installed on the rooftop. You can pair them 
together to create a central cooling plant for a large building. You can set up the 
chiller on the base floor or the roof. Also, it would help if you tried to place the 
cooling tower on the rooftop for optimum heat dissipation.
So, this is how you can use the chiller and cool together to maintain the 
temperature at the industrial units.
