Development of Direct-Use Projects: Preprint

PDF Version Also Available for Download.

Description

A geothermal direct-use project utilizes a natural resource, a flow of geothermal fluid at elevated temperatures, which is capable of providing heat and/or cooling to buildings, greenhouses, aquaculture ponds, and industrial processes. Geothermal utilization requires matching the varied needs of the user and characteristics of the resource in order to development a successful project. Each application is unique; guidelines are provided for the logical steps required to implement a project. Recommended temperature and flows are suggested for spas and pools, space and district heating, greenhouse and aquaculture pond heating, and industrial applications. Guidelines are provided for selecting the necessary equipment ... continued below

Geothermal utilization requires matching the varied needs of the user and characteristics of the resource in order to development a successful project. Each application is unique; guidelines are provided for the logical steps required to implement a project. Recommended temperature and flows are suggested for spas and pools, space and district heating, greenhouse and aquaculture pond heating, and industrial applications. Guidelines are provided for selecting the necessary equipment for successfully implementing a direct-use project, including downhole pumps, piping, heat exchangers, and heat convectors. Additionally, the relationship between temperature, flow rate, and the use of heat exchangers to provide heat to a space with hot water or hot air is provided for a number of applications, with suggested 'rules of thumb'.
