12. Relevance/Impact of Demonstration Geothermal Heat Pump Demonstration Utilize a ground sourced heat pump HVAC system. Variable Refrigerant Flow Technology Utilize variable refrigerant flow (VRF) heat pumps, allows for less compressors and enhanced internal heat recovery. Solar Thermal Desiccant Dehumidification Dedicated outdoor air supply units will utilize a thermally regenerated desiccant dehumidification section. A large solar thermal system along with a natural gas backup boiler will provide the thermal regeneration energy.
