  • Economizer

    The function of the economizer is as its name implies, to economize or save on cooling costs. Obviously, it costs money to operate the compressor. If the compressor can be shut down and the system still provide adequate cooling, energy savings can be realized. Heat internal to the building

  • White Paper: Computer Cooling Using Economizers and Free Cooling

    data center energy use doubled between 2000 and 2006 and predicts it will double again by 2012. Economizers-with their promise of "free-cooling"-are attracting much attention for their ability to reduce energy usage. Economizers also lessen wear and tear on precision cooling equipment and lower

  • WP #132: Economizer Modes of Data Center Cooling Systems

    In certain climates, some cooling systems can save over 70% in annual cooling energy costs by operating in economizer mode, corresponding to over 15% reduction in annualized PUE. However, there are at least 17 different types of economizer modes with imprecise industry definitions making

  • WP #136: High Efficiency Economizer-based Cooling Modules for Large Data Centers

    When a cooling plant operates in economizer mode, high energy-consuming mechanical systems can be turned off. A standardized, modular cooling plant designed to operate primarily in economizer mode not only reduces costs but also improves predictability and flexibility. This paper shows a new

  • Water Chiller Performance Calulations-Basic Cycle

    Water chillers are commonly employed to chill water for air conditioning systems. This chilled water is circulated thru cooling coils. Air is passed over the coils to be cooled and dehumidified for indoor comfort. The basic components of a water chiller are a compressor and motor, an evaporator, a c...

  • Steam Tables

    (Metric and US units) This program provides the thermodynamic properties of water using IFC formulation for industrial use. Knowing any two properties, the user is able to completely define the properties of water/steam. Unlike most steam table programs, this program also provides the user with the point''s location on the T-S diagram. Multiple points can be connected by a line, defining the user''s process system. It even gives you the steam quality.

  • Visual Studio 2005: Bridge the Gap Between Development and Operations with Whitehorse

    Microsoft is introducing a new suite of tools (code-named "Whitehorse") that will make it easier for you to design and implement systems that conform to a service-oriented architecture. Two of these tools -- the SOA Design Suite and the Class Designer -- support the graphical design of systems and components with support for code generation and support for bi-directional synchronization which lets you ensure that your diagram always represents your system design. This article introduces these tools and shows you how they''ll improve your design and development efforts.Brian A. Randell and Rockford LhotkaMSDN Magazine July 2004

Tips to Increase Efficiency and Heat Recovery

material, and operating conditions. Standard economizer -- Economizers transfer energy from the boiler exhaust gas to the boiler feedwater in the form of “sensible heat. ”   Sensible heat is created by the transfer of the heat energy of the exhaust gas to boiler feedwater.   An economizer captures and redirects sensible heat from the hot flue gas that normally goes up the boiler stack.   This sensible heat increases the temperature of boiler feedwater or makeup water...
