Technological Advances in Geothermal Energy Applications in Construction

The Geothermal Direct Use Engineering and Design Guidebook is designed to be a comprehensive, thoroughly practical reference guide for engineers and designers of direct heat projects. These projects could include the conversion of geothermal energy into space heating and cooling of buildings, district heating, greenhouse heating, aquaculture and industrial processing. The Guidebook is directed at understanding the nature of geothermal resources and the exploration of the resources, fluid sampling techniques, drilling, and completion of geothermal wells through well testing, and reservoir evaluation. It presents information useful to engineers on the specification of equipment including well pumps, piping, heat exchangers, space heating equipment, heat pumps and absorption refrigeration. A compilation of current information about greenhouse aquaculture and industrial applications is included together with a discussion of engineering cost analysis, regulation requirements, and environmental consideration. The purpose of the Guidebook is to provide an integrated view for the development of direct use projects for which there is a very large potential in the United States. Similar records in OSTI.

Geothermal Heating and Cooling Overview - The Basics

Geothermal Heat Pumps

Ground-source heat pumps use the earth or groundwater as a heat source in winter and a heat sink in summer! Direct-Use Equipment: 38 p. Several advantages and disadvantages are listed. Larger water-to-air heat pumps are available if multi-zone systems are required.

Therefore, GCHPs are inherently more efficient than units that use outdoor air as a heat source or sink if the ground coil is correctly designed. The lower the temperature of the geothermal water, the higher the flow rate required and the lower the efficiency. Because of the limited amount of data for GCHPs, not a great deal of data is available to support the claim of low maintenance in commercial buildings. Water-to-air heat pumps are relatively simple and potentially inexpensive devices.

The "Geothermal Direct Use Engineering and Design Guidebook", first issued in March, , has played a key role in highlighting and.

Geothermal heat pumps, also referred to as ground source heat pumps or geo-exchange, refer to systems that use the ground, groundwater, or surface water as a heat source or sink. Specific to their configuration, these systems are referred to as ground-coupled heat pumps, groundwater heat pumps, and surface water heat pumps, respectively. The first successful commercial project was installed in the Commonwealth Building in Portland, Oregon in As of , the United States had 12 gigawatts of installed thermal capacity from geothermal heat pumps, with an additional 80, units installed each year. Relative to air-source heat pumps, they are quieter, last longer, need little maintenance, and do not depend on the temperature of the outside air. Considerations including utility rates for electricity, natural gas, or other fuels can impact decisions to implement this technology.

    The Geothermal direct use industry potential, growth trends, needs, and how they are being met, are addressed. The high potential for industry growth, coupled with a rapidly expanding use of geothermal energy for direct use, and concerns over the greenhouse effect is the setting in which a new engineering and design guidebook is being issued to support the growth of the geothermal direct use industry. Recent investigations about the current status of the industry and the identification of technical needs of current operating district heating systems provide the basis upon which this paper and the guidebook is presented. The guidebook, prepared under the auspices of the U. Department of Energy, attempts to impart a comprehensive understanding of information important to the development of geothermal direct use projects. 😌
