Industrial water chillers are used in a variety of applications where chilled water or liquid are circulated through process equipment. A cooling tower is a large heat exchanger unit which provides cooling water to remove heat from a coolant which has been used to cool machinery, process fluids, or buildings. systems range vastly in size and design and are available as small, localized or portable chiller units for smaller applications or large central chillers designed to provide cooling for entire processes. Conversely, as the leaving chilled-water temperature rises, so do the refrigerant temperature and pressure. Choosing an adequately-sized chiller is critical for efficient and cost-effective process, machinery, and space cooling. There are two types of condensers used in chillers; air-cooled and water-cooled. Consequently, this lowers the pressure of the refrigerant and begins the cooling process again. The entire process is known as the refrigeration cycle. 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.

It consists of the following four main components; Let's see the using economizer on a different side to save energy. Some industries use metal-finishing chillers to cool the anodizing liquid in a heat exchanger or use a glycol/water as a cooling medium to lower the temperature inside the tank. 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. The gaseous coolant is absorbed by a concentrated absorbent such as Lithium Bromide or Ammonia, provided by a generator. Please fill out the form below. 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. A chiller provides consistent temperature and pressure to your industrial process. ... Reference: Trane Chiller. The high-pressure gas enters the condenser where ambient air or condenser water removes heat to cool it to a high-pressure liquid. It can be located inside the chiller or can be remotely located outside, but ultimately it rejects the heat from the chiller to the air. An industrial chiller is a refrigeration system used to lower the temperature of machinery, industrial spaces, and process fluids by removing heat from the system and transferring it somewhere else. The high-pressure liquid travels to the expansion valve, which controls how much liquid refrigerant enters the evaporator, thereby beginning the refrigeration cycle again. Industrial chillers are essential for temperature regulation in several industrial processes such as injection molding, metal plating, oilfield production, and food processing. Chillers consist of four basic components; an evaporator, a compressor, a condenser, and an expansion unit. When the cooling water meets with air, a small portion evaporates, lowering its temperature.

How Do Air Cooled Chillers Work? Below are some of the most common applications: Industrial chillers are used extensively in food production and processing operations which require a high degree of precision in temperature control. In place of the cooling water, air-cooled chillers use ambient air to reject heat from the refrigerant in the condenser. An injection molding chiller can supply a stream of supercooled fluid to cool the mold at an ideal rate to ensure optimum product quality. 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. For a given chiller, as the leaving chilled-water temperature drops, the refrigerant temperature and pressure must also drop. Contact us to find out more. Rather, they use a heat source e.g., solar energy or waste heat to drive the coolant through the system. The process starts with a low-pressure refrigerant entering the evaporator. 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. Instead of a wasteful, single-pass-through system, a chiller recirculates the cooling water. Chiller Plant systems are made up of: – Chiller/Condenser Unit – Chilled Water Pumps – Condenser Water Pumps – Cooling Towers – Makeup Water Tank – A/C Expansion Water Tank Chiller Plant TRANE Chiller. The process and melt must be maintained within precise temperature limits to prevent problems such as cracks, warping, and internal stresses in the final product. Inside the evaporator, the refrigerant is heated, causing it to undergo a phase change into a gas. The diluted solution of coolant and absorbent flows through a heat exchanger to the generator where it is heated. Economizer may use in air side or water side of the HVAC system. 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.
