This chilling technology is used by various industries to cool down the process machinery and the process using a freon chiller to cool a medium like air or water. To learn more about chillers in general and to help you make an informed decision about your own cooling problem, we are going to begin with a definition of a chiller and then move on to learning what a chiller can do for you, how to buy a chiller and what to look for when buying a chiller.
A portable chiller - is a single pump chiller, can be supplied with either air or water cooled condensers, used to cool one or two machines, process water flow limited to 2. A packaged chiller - is a two pump system, one pump for the evaporator, the other for the varying process, can be supplied with either air cooled or water cooled condensers, no process water flow restrictions but this type of chiller is not expandable as plant cooling load increases.
A central chilling system - is where one or more central chillers are connected to a common two pump tank set, stand-by pump s , can be added, and chillers can be added to the maximum cooling capacity of pump tank. A central cooling tower system - is where one or more cooling towers are connected to a common two pump tank set, standby pump s , can be added, and towers can be added to the maximum cooling capacity of pump tank. Central tank sets allow various types of chillers air, water cooled, makes and tonnage to work together on the same chilling system.
As well, different types, makes, and tonnage of cooling towers to work together on the same tower system. While most industrial operations use a combination of these cooling solutions, most will involve a chiller. So, what is a chiller? A modular cooling system - is a cooling system with multiple chillers that couple together to make a complete or expandable chilling system, each chiller has dual compressors with a dual circuit evaporator and condenser.
You can add up to 12 chillers total of 24 compressors in one bank. Each bank is controlled from a System Remote Master SRM that stages the compressors on leaving chilled water temperature and leadālags the compressors to equalize run time, it logs the number of compressor starts, compressor run hours, and stores up to alarm faults in its memory. The SRM can talk to your plant PLC and send as much of the operating and fault conditions as you require, the number of compressors operating and those off line and why.
Combined with our chilled water and tower water pump packages, you have a complete cooling system that communicates the operating and fault conditions of each piece of equipment in the system to your plant PLC and can be expanded as your plant grows. When people first encounter the term "chiller" if they don't first think of a scary movie they usually think of something that creates cold or cools the surrounding air like an air conditioner or the maybe even a refrigerator.
This is a bit misleading. A chiller consists of the following six main components:. Compressor - takes this gas and increases its pressure so that ambient air or water can remove the heat.
Condenser - rejects heat gained by the gas using ambient air or cooling tower water to condense the gas back to a liquid for use again by the evaporator. Pump - circulates coolant from the holding tank to the evaporator and from the evaporator to the machine or process being cooled and back to the tank. Control Panel - houses temperature controller, compressor contactor, pump starter, 3-phase fuses, control transformer, safety controls, run and fail lights.
While it is true that a chiller is a device that cools something else, i. In short, it's a heat removal device. A basic chiller has two circuits: In the water circuit, a pump circulates the water from the holding tank to the evaporator which cools the water by transferring the heat to a refrigerant, the water then goes on to the process in a portable chiller or back to the tank in a packaged or central chiller.
In the case of an industrial chiller, the principle is the same. The heat is removed from the condenser either by a plant cooling tower water system, or outdoor air for remote condenser and outdoor air cooled chillers, or by plant air for portable or indoor heat reclaim chillers.
As one can imagine chillers are extremely important in the industrial world where there are literally millions of machines that generate a lot of heat. If these machine are to last any time at all, they need to be cooled. This is where chillers come in. Some of the more common applications are listed below:.
Plastics In the plastics industry, a chilling system cools the hot plastic that is injected, blown, extruded or stamped. A chilling system can also cool down the equipment that is used to create plastic products hydraulics of the molding machine, gear box and barrel of the extruder that saves on energy and on the wear and tear of the machine itself. Plastics , Injection Molding.
Printing In the printing industry, a chiller not only removes the heat generated by the friction of the printing rollers, but cools down the paper after it comes out of the ink drying ovens in the process. Laser In the laser cutting industry, light projection industry, etc. Rubber In the rubber industry to cool the multizone water temperature control units of the rubber extruder barrel, cool the rubber mill, calendars and bambury mixers. Beverage In the beverage industry, a chiller removes the heat gained from the process during mixing, cooking, or after pasteurizing the product.
Medical If you use high tech equipment for magnetic resonance imaging, scanning, blood cooling and laboratory testing, you'll need a cooling system to remove all the heat generated.
