Fort Knox established energy efficiency standards in 2004 that were implemented in Building 1110. This included upgrades to HVAC, windows, lighting, insulation, and eliminating natural gas for heating and hot water. As a result, energy usage decreased 76% and earned an Energy Star award in 2008. The building now uses a geothermal heat pump system and high-efficiency electric heat pump water heaters to meet its needs, reducing costs and carbon footprint.
During this seminar we will discuss the design and operational characteristics of a geothermal HVAC system. We will explore the different configurations of a geothermal system including standing column, horizontal loop, vertical loop and pond loop systems. We will compare geothermal HVAC systems with conventional HVAC systems relative to first costs, operating costs, functionality and maintenance focusing on commercial buildings.
Learning Objectives:
-Develop an understanding of how a geothermal heat pump system operates.
-Have the ability to assess if a building is a candidate for a geothermal heat pump system.
-Understand the environmental, operational and cost benefits of a geothermal heat pump system.
Homeowners with natural gas water heaters have difficulty justifying the expense of a more efficient condensing heater. Combination space and domestic hot water systems bundle together the two loads, which saves energy and makes them more cost-effective. These systems also help eliminate combustion safety concerns.
Historically, mechanical contractors have custom engineered and pieced together combi systems in the field, paying little attention to efficiency and optimization. But condensing heating plants will only reach their energy saving potential when all components are designed and installed correctly.

ज्ञान प्राप्त करने के तीन तरीके है. पहला चिंतन जो सबसे सही तरीका है. दूसरा अनुकरण जो सबसे आसान तरीका है और तीसरा अनुभव जो सबसे कष्टकारी है ~ कन्फ्यूसियस
THE PRESENTATION SPEAKS ABOUT THE BASIC IDEAS ABOUT EFFICIENCIES OF BOILER AND TURBINE IN A COAL BASED THERMAL POWER PLANT WITH THE DESIGN EFFICIENCIES AND HEAT RATE. IT ALSO THROWS LIGHT ON THE VARIOUS IMPROVEMENTS IN HEAT RATE AND EFFICIENCIES.THAT CAN BE ACHIEVED.
Heat rate is the pulse rate of a power plant to know the health of the plant.
Net heat rate is the single parameter that encompasses total performance indices of a power plant.
An innovative technology to increase the heater capacity without increasing the coil side pressure drop in fired heaters.
Furnace Improvements has implemented this technology in many fired heaters around the world. This technology is useful specially for Reformer heaters as coil pressure drop is limited for those heaters, typically 2-5 psi.
