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.
