The refrigeration circuit is the most technical part of how a chiller works.The refrigeration cycle uses the principles of thermodynamics to efficiently move heat from one area to another. Some manufacturers send options in pieces to be field installed. We excel – so you can, too. An air-cooled condenser uses ambient air to cool and condense the hot refrigerant gas back down to a liquid. The chillers will produce “chilled water” which is pumped out around the building to the Air Handling Units (AHU’s) and Fan Coil Units (FCU’s) Which remove the unwanted heat from the building and transfer it into the chilled water loop. Trane Earthwise CenTraVac chiller provides reliability and longevity with chillers running for more than 50 years. They also help save costs on purchasing separate HVAC systems for cooling. For a given chiller, as the leaving chilled-water temperature drops, the refrigerant temperature and pressure must also drop. This process of heating and cooling the refrigerant and changing it from a gas to a liquid and back again is the refrigeration cycle. They are particularly useful for medium to large scale cooling operations (from 150 – 6000 tons of refrigeration). This type of chiller uses refrigerants to cool process fluids and spaces. View More.

We are the premier commercial chiller team in the greater NC area. We will also briefly touch on cooling towers (an alternative or supplemental cooling system) and special chillers like glycol and centrifugal chillers. There are many types of refrigerant and applications depending on the temperatures required but they all work on the basic principle of compression and phase-change of the refrigerant from a liquid to a gas and back to a liquid. In the case of chillers, heat is taken from the fluid being chilled and transferred to the ambient air. The RTAD UCM-CLD Internal Water Flow Loss protection works on the principle that in the absence of chilled water flow the entering chilled water sensor (located in the tube bundle) will sense a drop in temperature in reference to the leaving chilled water sensor. This cool fluid removes heat from the process and the warm fluid returns to the chiller. Chillers consist of four basic components; an evaporator, a compressor, a condenser, and an expansion unit. 175-450 ton units (60 hz), 125-410 ton units (50 hz) (150 pages) Note the direction of arrows: Heat engine is defined as a device that converts heat energy into mechanical The low-pressure gas enters the compressor where it is compressed to high-pressure gas. Basic Refrigeration Cycle A centrifugal chiller utilizes the vapor compression cycle to chill water and reject the heat collected from the chilled water plus the heat from the compressor to a second water loop cooled by a cooling tower. The gaseous coolant is absorbed by a concentrated absorbent such as Lithium Bromide or Ammonia, provided by a generator. If your facility uses process fluids or heavy-duty machinery that generates heat, you’ll need an industrial chiller system to cool your processes and internal machine components. It is very common to use water or a water/glycol solution to transfer the heat to and from the chiller which may require the process chiller to have a reservoir and pumping system. Instead of a wasteful, single-pass-through system, a chiller recirculates the cooling water. An injection molding chiller can supply a stream of supercooled fluid to cool the mold at an ideal rate to ensure optimum product quality. How Do Air Cooled Chillers Work? Chillers consist of four basic components; an evaporator, a compressor, a condenser, and an expansion unit. A refrigerator or heat pump is simply a heat engine operating in reverse.

The now-concentrated absorbent is recycled as well. Contact us to find out more. This is known as “evaporative cooling.”. Glycol chillers are special types of chillers which use propylene glycol, an anti-freeze, in the system. The high-pressure liquid travels to the expansion valve, which controls how much liquid refrigerant enters the evaporator, thereby beginning the refrigeration cycle again. Download 414 Trane Chiller PDF manuals. The diluted solution absorbs the coolant while the heat is being absorbed by the cooling water. operating chillers are loaded to equal percentages. In many situations, you can pair a chiller and cooling tower together for more efficient industrial chilling. The high-pressure refrigerant goes to the condenser which rejects the heat using cooling water from a cooling tower or air from the surroundings, condensing it into a high-pressure liquid. It consists of the following four main components; It’s 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. * Required Fields, Address: 14343 Interdrive East, Houston, TX 77032, Request Product Manual | Privacy Policy | Sitemap | Marketing Provided by MARION Integrated Marketing.

Industrial chiller systems can be used for cooling operations in diverse industries. In manufacturing plants which generate a lot of heat from the heavy-duty machinery they use, a chiller can help to prevent extremes of temperature in the offices and other working spaces. In the evaporator, heat from the process water or water/glycol solution boils the refrigerant, which changes it from a low-pressure liquid to a low-pressure gas. Regardless of your industry and process, making sure that you have sufficient cooling is critical to productivity and cost savings. The diluted solution of coolant and absorbent flows through a heat exchanger to the generator where it is heated. Typical Chiller Plant. For the same building load, the load on each chiller can be significantly different and depends on the chilled-water system configuration. 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). In most process cooling applications, how chillers work is that a pumping system is used to circulate cool water or a water/glycol solution from the chiller to the process. Reducing the pressure over a liquid decreases its boiling point and increasing the pressure  increases its boiling point. 6.2 Preferential Loading When a chiller is located on the load side of the Depend on Thermal Care for efficient and reliable central chilling systems – no matter what the need or application including indoor chillers or outdoor water chillers. © 2015 - 2021 Thermal Care, Inc., All Rights Reserved.
