Morning Session: 8:30 am – 12:30 pm
Lunch (On your own): 12:30 – 1:30 pm
Afternoon Session: 1:30 – 4:30 pm
General Overview of Geothermal Heat Pumps and
Application to Indoor Thermal Comfort
Forced air and domestic hot water
Applying geo heat pumps to HVAC systems
Integrating heat pump hot water production with HVAC
Calculating heating and cooling loads
Effects of air flow and insulation
Measuring comfort
Understanding efficiency
Understanding Earth Loop Systems
Architecture of closed loop systems
• Horizontal ground loops
• Pond loops
• Vertical ground loops
Applications for open loop systems
• Standing column wells
• Single well systems (pump and dump)
• Two-well systems
Evaluating the topography
Measuring soil conductivity
Ground loop environments
Designing Geothermal Systems
Determining loop type
Making heat loss calculations, consider the future
Sizing the unit, consider variable speed (or at least dual speed) units
Sizing the loop field, again, consider the future
Balancing field flow
Oversize for greater efficiency
Choosing Systems and Materials
Basic components for geothermal heat pump systems
• Circulating pump
• Heat pumps
• Heat exchangers
• Field manifold
• Forced air systems
• Hydronic systems
Domestic hot water options
• Tank and W-W heat pump
• Hot gas heat recovery
• Can be supplemented with gas or electric
Evaluating the Benefits of Geothermal Systems
Incentives for using geothermal
• Tax credits
• Utility and other incentives
• Stability of utility cost
• Maintenance
Environmental benefits for applying geothermal
• Reduced use of nonrenewable energy
• Lower water and sewer use

Speakers
James Hardin
Geothermal Innovations, LLCSr. Vice President of Engineering, Geothermal Innovations, LLCMr. Hardin has spent the past 40 years at the forefront of developments in energy efficiency. He developed several patented technologies, including the Water+ system, the Well2Well system, BiSec heat exchanger, and the GEX 4 heat exchanger, plus several other energy applications in the geothermal, energy management, and lighting industries. He works under a philosophyof increasing operational efficiency by providing higher-quality, energy-related services at reduced levels of overhead. Prior to forming Hardin Geothermal, Mr. Hardin was energy manager for Illinova Energy Partners, Inc., managing multimillion dollar construction projects for healthcare facilities and aluminum processing plants throughout the USA. Mr. Hardin began his career in the 1980s as senior energy manager/engineer in charge of installing geothermal systems for petrochemical plants in Braziland later in West Africa.
