Chillers Are you wondering whether a cooling tower vs. How a Cooling Tower Works A 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. Cooling Tower Construction A cooling tower is comprised of water pumps and a large basin. Cooling Tower Applications Cooling towers are typically used in large-scale cooling operations such as power generation, oil and gas refining, and thermal power stations.
How an Industrial Chiller Works An 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.
Recent Posts. October September August July June May April March A crossflow tower is designed to make the hot process water flow down the media fill due to gravity. This will occur while air blows horizontally, which cools the water down. The tower gets its name because of the airflow direction. Hot water basins are placed just above the fill, which allows the water to be evenly distributed. Industrial plants will commonly choose these towers for their cooling needs.
Forced draft towers are extremely powerful, yet cost-effective at the same time. In these towers, low-potential heat is removed during the production process. A counterflow of water and air results in a heat transfer. Chemical and paper industries frequently choose forced draft models.
A fan at the top of the tower pulls the air upward in induced draft models. This fan induces the hot and moist air out of the discharge. A powerful exiting air velocity is the end result here.
Induced drafts will prevent any discharged air from flowing back into the intake point. The condenser water and the refrigerant never mix, they are always separated by the pipe wall, heat just transfers through the wall. Once the condenser water has passed through the condenser and picked up the unwanted heat, it will head up to the cooling towers to dump this heat and return cooler ready to collect more heat.
Cooling tower: The cooling tower is usually located up on the roof and is the final destination for the unwanted heat in the building. The cooling tower contains a large fan which blows air through the unit. The condenser water is pumped up to the cooling towers and it is sprayed into the air stream. The cool ambient air will enter and come in direct contact with the spray of condenser water in an open cooling tower this will allow the heat of the condenser water to transfer into the air and this air is then blown out into the atmosphere.
The condenser water then collects and heads back to the chillers condenser ready to collect more heat. Check out our special tutorial on cooling towers here.
Thank very much for this video, was goog information for my work. Appreciate your detailed explanation on this matter. Thank very much Mr. Muchas gracias por el video, fue de muy buena informacion para mi trabajo.
Se le apercia mucho su detallada explicacion en este menester. Thanks very you are doing a great job. Today I understand fully house the chiller couple with AHU work. This is a great, in-depth video of how these different assets work together to produce cool air. Thank you.
Thanks for sharing your thoughts with all of us through your post. Good job, Keep posting and share your valuable tips with us. Hi Paul, Thanks for the sharing. By the way, how we choose the best choice between air cooled and water cooled?
I work in a school building with this type of system cooling tower on roof. I have been there for 12 years and in the same room for 7 years. I have multiple chemical sensitivity and asthma, and I have never had a problem with our system. However, three weeks ago I began to smell an overwhelming odor to me blowing from the vent in my classroom.
The building is 20 years old and the air has gone out three times this year already. Any ideas on what could be making this noxious odor??
I am desperate!!! Very hard to tell from the information provided. What does it smell like? The system is basically just metal ducting around the building with air moving inside.
Possibly someone has placed a bin near the air vent intake grille. Chillers are used in areas which will not be affected by the additional heat discharged by it. In fact many installations rely on the chiller to produce heat during the cooler months.
Typically facilities to find chillers in include refrigeration and plastic industries. Cooling towers are found commonly in mechanical processes and electric power generation. Power plants are commonly located near lakes or rivers which are tapped to provide cooling to the water circulating in the system. The water coming out of the condenser in these plants must be cooled to sustain the process.
Chillers use compressors and heat exchangers to cool and are not as energy efficient as cooling towers. While the fans and water pumps in cooling towers do consume energy they also provide much greater cooling capacity.
Chillers which use air cooling are also not as efficient as water cooling chillers. We all know that a wet surface transfers heat better than one that is dry.
