When it comes to heating and cooling an office space or larger building, the use of a commercial or industrial-sized HVAC system is needed in order to properly meet the needs of the entire building. In order to have a better understanding of how the HVAC system in a larger office building works, you need to know how the chiller, cooling tower, and air handling unit work together.
A water-cooled chiller is a large piece of equipment used industrially and located in the interior of a building, containing the evaporator and the condenser. The cooling tower acts as a large heat exchanger that sits on the roof of the building.
When these two items work together, it becomes possible to condition the air in large open spaces, such as industrial buildings and factories.
The minimum system components of the central cooling plant include:. The location of the chiller depends on the type of chiller that is used, and rooftop ones are usually air-cooled while the basement chillers are water-cooled. Both perform the same function, which is usually to generate cold water for the air conditioning by removing the unwanted heat away from the building.
The only difference is the way that the chiller discards the heat. Air-cooled chiller will use fans to expel the cool air over the condenser to remove the heat from the system and air-cooled chillers do not use a cooling tower. The air that enters the cooling tower from outside has a different density than the interior air. When these two types of air meet, the dense and hot air will rise out of the cooling tower while the cooler air falls into the water below, which ensures that the cooling process occurs naturally without the use of fans.
If you require unlimited cooling water for your industrial application , a natural draft cooling tower may be the right choice for you. There are two notable types of industrial chillers that you can select for your cooling needs, which include a water-cooled chiller and an air-cooled chiller.
If you decide to use a water-cooled chiller, you should keep in mind that they require the use of condenser water treatment to ensure that any mineral buildup is eliminated.
The buildup of mineral deposits causes issues with heat transfer, which means that the efficiency of the water-cooled chiller will be reduced until the issue is cleared up. Any unwanted heat from the chiller will be sent into the cooling tower before being dispersed into the outside air.
An air-cooled chiller are systems that absorb heat from the water before transferring the heat outside of the system and into the air surrounding the chiller unit. Once the heated air is transferred outside of the unit, it will lower in temperature and turn back into a liquid, which allows for a continuous cooling cycle. Any production of excess heat with an air-cooled chiller can actually be beneficial during the cold winter months when the heat could be used to warm the plant and reduce your monthly energy bills.
Industrial water chillers are used in a variety of applications where chilled water or liquid are circulated through process equipment. Commonly used to cool products and machinery, water chillers are used in a multitude of different applications including injection molding , tool and die cutting, food and beverage , chemicals, lasers, machine tool, semi-conductors and more.
The function of an industrial chiller is to move heat from one location usually process equipment or product to another place usually the air outside the manufacturing facility.
Regardless of your industry and process, making sure that you have sufficient cooling is critical to productivity and cost savings. If this heat is not removed, it will accumulate over time causing reduced production times, equipment shutdowns, and even premature equipment failure.
It is necessary to incorporate cooling into industrial process system design to avoid these issues. Using a chiller to provide cooling has multiple benefits.
A chiller provides consistent temperature and pressure to your industrial process. Welding Chillers. Industries Metal Finishing Chillers. Request a quote.
Cooling Tower vs. Posted: July 10, Categories: Blog. Author: Mike Marrone. Cooling Towers vs. 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.
