How Does a Cooling Tower and Chiller Work Together?įor small-scale applications such as chilling small rooms and exhausts of equipment, you can use a suitably sized air-cooled or water-cooled chiller and a portable cooling tower installed on the roof of your building.

Feel free to use our tools to help make an informed chiller capacity calculation for your application. Cooling towers and chillers can be used independently or in combination for large-scale, efficient cooling.īefore making the decision to utilize both, consider factors such as your required volume of cooling, access to water, available space, and budget. Chiller - Do I Only Need One or Both?Īs you’ve now learned, the main difference between a chiller and cooling tower In water-cooled chillers, a cooling tower provides water to cool and condense the coolant.Ĭold Shot Chillers has several types of chiller systems available including water-cooled chillers (that use a stream of water from a cooling tower to reject heat from the coolant in the condenser) and air-cooled chillers (that use ambient air and cooling fans to remove heat from the condenser coolant). In air-cooled chillers, the hot coolant which has undergone a phase change into a gas (in the evaporator) is exposed to the air around the system which cools it and turns it back into a liquid. Industrial chillers can be air-cooled or water-cooled, depending on the medium for dissipating heat from the system. Then the hot (used) refrigerant is cooled and regenerated with ambient air or water from a tower or outside source, and then returns for recirculation. How an Industrial Chiller WorksĪn industrial chiller removes heat from hot, gaseous coolant coming from a process using water or heat transfer fluid and transfers this heat to a refrigerant. Again, depending on system design, a chiller can typically hold a closer temperature tolerance with respect to a desired temperature set point. Some chiller designs can allow for cooling temperatures from 70F-100F+ if designed to accommodate such conditions. Chillers can achieve typical temperatures from 70F and below all year. Typical low temperature coolant temperatures during summer conditions can rarely go below 75F-80F while using a cooling tower. One very important deciding factor on choosing a chiller or a cooling tower should be based on the required coolant temperature.Ĭooling tower temperatures vary based on local wet bulb conditions and the ambient air temperature. Cooling Tower ApplicationsĬooling towers are typically used in large-scale cooling operations such as power generation, oil and gas refining, and thermal power stations. The basin is a large hyperboloid, cylindrical or rectangular structure made of plastic, composite, concrete or steel and contains the spray nozzles, cooling tower fill media, and other heat dispersion equipment.Īlthough large cooling towers structures (over 200 ft in height and 100 meters in diameter) are common, there are smaller systems that can be installed at smaller sites and on top of buildings. The pumps provide water for cooling while the basin collects and drains discharged water from the system. Cooling Tower ConstructionĪ cooling tower is comprised of water pumps and a large basin. Spray nozzles inside the tower spray the water on a fill material whose larger surface area allows for maximum contact with air and increases the rate of evaporation.Ĭooling fans located within the tower aid the cooling process, and the drift eliminators remove the tiny droplets of water produced in the tower air stream during evaporation. Heated water from an industrial process can enter a heat exchanger or condenser and flow through the pipework into the cooling tower for heat removal, or flow directly through the tower.
It is common to find cooling towers conveniently situated near bodies of water such as lakes and rivers to ensure a constant supply of water for cooling. When the cooling water meets with air, a small portion evaporates, lowering its temperature. How a Cooling Tower WorksĪ cooling tower is a large heat exchanger unit which provides cooling water to remove heat from a coolant (most often water) that has been used to cool machinery, process fluids, or buildings. To find out which system is best for your cooling needs, you should understand how cooling towers and chillers work. However, they differ in their mode of operation. industrial chiller is better for your application? Cold Shot Chillers is here to help! Cooling towers and industrial chillers serve similar purposes – both systems can be used to cool industrial processes such as food processing units, metal plating and more.
