Daikin Applied has expanded its Magnitude WMC chiller line to include four additional sizes – WMC125, 200, 225, and 275. The product is ideal for most commercial applications including hospitals, small to midsized data centers, schools, and office buildings. The company says the expanded line provides greater flexibility for engineers who can now closely match chillers to the specifications of the job and apply magnetic bearing chillers on many more projects.
Our BAS columnist makes a house call to prescribe one method of applying retrofit expertise, including the success story of a hospital with mysteries or maladies that required attention in VAV and chillers, air handling strategies, OR ventilation, and beyond.
A quiet learning environment, consistent comfort, and energy efficiency topped the list of requirements at Northbrook Junior High School in selecting chillers as part of a $1.88 million life-safety improvement renovation project. The two-story, 135,000-sq- ft school was originally built in 1958 and now serves 650 students in grades six through eight. The renovation project included replacement of all heating and cooling system components.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
