Geoclima announced that they earned the trusted AHRI Certified® mark, an assurance of the product’s performance, for the water cooled range of products as an original equipment manufacturer (OEM).
University of Alabama at Birmingham obtained an annual energy savings of $60,000 after Bernhard TME Engineering (TME) optimized the university’s district chilled water system. The chilled water is distributed to 48 buildings on campus to supply the air conditioning systems in the hot and humid southeastern U.S.
For building owners looking to install new chillers or replace an existing system, the options can be daunting, but selecting the most appropriate chiller for an individual application does not have to be complicated.
HVAC chiller manufacturers are offering a range of products in multiple configurations that use new refrigerants, consume less energy, communicate more effectively, can be serviced more easily, and may be designed to fit a wide range of applications.
Ilios Inc., a subsidiary of Tecogen® Inc., announced it has signed a manufacturers’ representative agreement with Sam DeSanto Co. Inc. (SDCI), a Mid-Atlantic based HVAC and plumbing equipment supplier. Concurrent with the signing, SDCI placed an order for an Ilios water-source high-efficiency water heater.
This analysis shows how a water-cooled 500-ton chiller system when compared to a 500-ton air-cooled chiller system results in approximately $45,000 in annual operating costs savings. Additionally, the water-cooled system reduces peak energy demand by 45 percent.
An Arup-designed chilled-water system at University of California, San Francisco (UCSF) has earned a $757,000 energy efficiency award from PG&E, and a 2013 Higher Education Energy Efficiency and Sustainability Best Practice Award in the HVAC Retrofit category.
Ameresco’s energy savings performance contract for Austin Energy’s Domain District Cooling Plant includes the installation of a new chilled water storage system that will help reduce the plant’s peak electricity usage by shifting the chilled water load and associated electric consumption from on-peak to off-peak hours.
The Automatic Tube Cleaning System (ATCS) provides energy-saving, on-line condenser tube cleaning for water-cooled chiller applications. The system periodically injects sponge balls into the condenser water stream, and prevents condenser tubes from developing scale or microbial fouling deposits.
