Book excerpt: Colorado State Capitol Geothermal Project - Final report is redacted due to space constraints. This project was an innovative large-scale ground-source heat pump (GSHP) project at the Colorado State Capitol in Denver, Colorado. The project employed two large wells on the property. One for pulling water from the aquifer, and another for returning the water to the aquifer, after performing the heat exchange. The two wells can work in either direction. Heat extracted/added to the water via a heat exchanger is used to perform space conditioning in the building.
Download or read book Geothermal Utilization at Castle Oaks Subdivision Castle Rock Colorado written by and published by . This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Designs of geothermal systems for using warm water from four aquifers of the Denver Basin are presented. Advantages of using heat pumps with the geothermal resource are discussed. Two design cases-one with separate heat load and heat pump, and the other with the heat pump and heat load located at the well site-are evaluated in terms of pump costs, operating costs, and payback periods. The 20-year delivered energy costs for the two geothermal systems would be slightly less than those for natural gas ($5.64 to $6.42 versus $6.70 per million Btu).

This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The State Highway Department Building in Burlington has been evaluated in this geothermal energy appraisal. While there is no known geothermal resource at Burlington, a shallow water aquifer - Ogallala Aquifer - does exist beneath Burlington at depths of 200 to 300 feet. One particular water well is reported to be producing water at 59°F to 63°F at 800 to 1000 gpm. Therefore, the Ogallala is being considered as a source of warm water for the use of water-to-air heat pumps for space heating of the Highway Department Building. The geothermal energy economics are evaluated for two options: (1) a new water well drilled on the site of the Highway Department Building and (2) the purchase of warm water from an existing City of Burlington water well. The latter option is evaluated only for the 12 percent/9 percent (through 1984/through 2000) natural gas price escalation case, whereas the former option is evaluated for both the 15 percent and the 12 percent/9 percent schedules. The results of the economic evaluations generally indicate that heat pumps would not be economically competitive, particularly if the state purchased city water at the current water rates. Fuel price escalation rates greater than 15 percent per year can shift the heat pump shallow well option to a marginal position. The principal institutional/environmental issue to be addressed for the Burlington facility is an existing ordinance which only allows the city to drill water wells within the city.

Download or read book Geothermal Heating and Cooling written by Stephen P. Kavanaugh and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geothermal Heating and Cooling is a complete revision of Ground-Source Heat Pumps: Design of Geothermal Systems for Commercial and Institutional Buildings, which is recognized as the primary reference for nonresidential ground-source heat pump (GSHP) installations. This new work takes advantage of the many lessons learned since the time of the original publication, when GSHPs were primarily residential applications. Many improvements have evolved, and performance data, both positive and negative, is now available to guide the development of best practices. This essential guide for HVAC design engineers, design-build contractors, GSHP subcontractors, and energy/construction managers also provides building owners and architects with insights into characteristics of quality engineering firms and the information that should be provided by design firms competing for GSHP projects.This revision draws on new ASHRAE and industry research in critical areas, as well as measured data from long-term installations and optimized installation practices used by high-production GSHP contractors. Nearly all chapters and appendices were completely rewritten, and they include coverage of closed-loop ground (ground-coupled), groundwater, and surface-water systems plus GSHP equipment and piping. Additional information on site characterization has been added, including a new hydrogeological chapter. Another new chapter contains results of recent field studies, energy and demand characteristics, and updated information to optimize GSHP system cost. While other publications deal primarily with ground-coupled heat pumps, this text includes detailed coverage of groundwater, surface-water, and GSHP costs.Tables, graphs, and equations are provided in both Inch-Pound (I-P) and International System (SI) units. As a bonus, supplemental Microsoft® Excel® macro-enabled spreadsheets for a variety of GSHP calculations accompany the text.

This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Four state-owned building complexes ahve been evaluated within the city of Durango: The State Fish Hatchery, Fort Lewis College, new State Highway Department Building near the Bodo Industrial Park, and the National Guard Building. Three of the state facilities in Durango are evaluated for geothermal systems on thea ssumption of taking geothermal water from a trunk-line originating at the area northof Durango: State Fish Hatchery, Fort Lewis College and new State Highway Department Building. The National Guard Building is evaluated on the basis of a water-to-air heat pump, with warm water derived from a hypothetical shallow aquifer immediately below the building site. Two geothermal options were separately evaluated for Fort Lewis College: a central heat exchanger system for delivery of 145°F heating water to the campus buildings and a central heat pump system for boosting the heating water to 200°F prior to delivery to the buildings; both systems require the installation of a distribution piping network for the entire campus area. Retrofit engineering for the State Fish Hatchery provides for the installation of a small scale central distribution piping system to the several buildings, a central heat excanger coupled to the geothermal trunk line, and the use of various fan coil and unit heaters for space heating. An option is provided for discharge-mixing the geothermal water into the fish ponds and runs in order to raise the hatchery water temperature a couple degrees for increasing fish production and yield. The heating system for the new State Highway Department Building is redesigned to replace the natural-gas-fired forced-air furnaces with a heat exchanger, hot water fan coils and unit heaters.

Book excerpt: Ground-Source Heat Pumps presents the theory and some of the most recent advances of GSHPs and their implementation in the heating/cooling system of buildings. The authors explore the thermodynamic cycle with calculation, operation regimes and economic indicators and GHG emissions of a vapor compression heat pump. They go on to examine substitution strategies of non-ecological refrigerants and types of compressors and heat pumps, before delving into the different GSHP systems, as well as their compared economic, energy and environmental performances using classical and optimized adjustment for various operating modes. Surface water heat pumps and ground water heat pumps are covered, and special focus is given to both vertical and horizontal ground-coupled heat pump systems, for which modelling and simulation is discussed, and experimental systems are described. Due to its advanced approach to the subject, this book will be especially valuable for researchers, graduate students and academics, and as reference for engineers and specialists in the varied domains of building services.
