Compare and understand the most common calcium carbonate scale prediction methods for cooling waters. Learn where and why some methods are inaccurate, and understand how an accurate prediction method can optimize a calcium carbonate scale-control program as well as provide a cost reduction in cooling water treatments.
ASHRAE and the International Institute of Refrigeration (IIR) established definitions for five refrigeration keywords: cooling, refrigeration, chilling, freezing and cold chain. The definitions are the result of more than a year of discussions and were established to clarify the meaning of basic terminology.
When compared to space cooling, process cooling — or the removal of heat from the fluid that serves water-cooled equipment used in a manufacturing process — is a bird of a different feather. Interesting though — and the source of some fascination among those in the cooling trade — is that much of the equipment, tools and techniques remain the same.
The mechanical rooms in large multi-building industrial facilities are the hub of process temperature and climate control. Areas such as central utility plants, boiler and chiller rooms, mechanical and electrical rooms, and fuel rooms house myriad process cooling and heating equipment as well as systems for comfort heating, ventilation and air conditioning equipment and systems.
Shell-and-tube heat exchangers — first introduced in the 1900s — have long been used in all types of process applications because of their robust design. Shell-and-tube heat exchangers are able to withstand high pressures and temperatures, and these features are among the reasons for their wide use.
A portable, clean-in-place pump system, Model GDS-100 is suited for larger descaling cleanings to remove limescale, calcium and mineral deposits, rust and other contaminants found on process manufacturing equipment.
Series GS-400 supports safety compliance inside of machinery rooms, mechanical equipment rooms, chiller plants, cold storage facilities and walk-in freezers by monitoring for refrigerant leaks for numerous gases, including HFCs, HFOs, HCFCs, CO2 and NH3 (ammonia).
Manufacturing processes can produce adverse ambient conditions that can affect employees, production uptime and product quality. Using ancillary systems with production equipment can produce excess heat in the building, sometimes increasing the ambient temperature by 20°F (11°C) or more. These temperature fluctuations can create a difficult environment for employees as well as equipment.
Sound test data helps manufacturers meet noise level requirements. Multi-Wing’s white paper offers equipment manufacturers an understanding of the challenges associated with sound measurements in field tests. The white paper explains sound propagation in simplified, ideal and real-world conditions. A video is also available.
Engineers, end users, wholesalers, manufacturers and contractors involved in natural refrigeration using ammonia and carbon dioxide will gather, learn and share at the annual IIAR conference in Phoenix on March 3-6.
