Removing oil from the chiller system results in a more simplified chiller design that eliminates frequent maintenance tasks required on traditional oiled chiller systems such as analyzing the oil for contaminants and changing the oil and filters.
The system includes a 2,000-ton open cooling tower with six condenser water pumps and four 500-ton centrifugal electric chillers with two condenser water pumps for process chilled water cooling.
This article demonstrates the System Energy Equilibrium (SEE) Plant Model can duplicate the performance of a Kansas City chiller/tower manufacturer’s data.
New oil-free, magnetic bearing chillers with Arctic Boost option allow the building at 1120 Vermont Ave. NW to consistently and predictably achieve a system 0.08 kW/ton efficiency.
One engineer’s quest to develop a math model, solved by computer, of a system that duplicates the real-time chiller system performance at all operating conditions within about 3%.
After years of chasing the attractive efficiency numbers offered by water-based evaporative systems, many data center providers are giving air-cooled chillers a second look.
It’s no secret that data centers require a lot of energy. The main driver of data center design engineers’ work is to provide energy-efficient, reliable, and cost-competitive HVAC systems.
