As computer manufacturers pack more and more processing power into smaller packages, the challenge of data center cooling becomes more complex - and more critical. New servers and communication switches generate as much as ten times the heat per square foot as systems manufactured just ten years ago.. As these new systems are installed alongside previous generation systems, they create hot zones within the data center that cannot be effectively managed using traditional approaches to cooling. New strategies and technologies must be implemented to provide the cooling high-density systems require for reliable operation.
Foods companies all over the country are using thousands of gallons of DOWFROST™ Heat Transfer Fluid from The Dow Chemical Company to manage heating and cooling during the incredibly heat and cold sensitive chocolate manufacturing process.
It's important to remember that Standard 15 applies to more than large chillers. In this Newsletter, the requirements of Standard 15 are exsamined as they apply to smaller refrigeration systems - specifically, packaged units, split systems, and the newer variable refrigerant flow (VRF) systems.
