DOE Phase 1-2 Grants
Melink awarded over $1 million to reduce costof geothermal HVAC
and improve marketpenetration for greater energy efficiency
and savings in homes and buildings
-
VRF
What’s the Big Deal?
• Simultaneous heating and cooling – geo does this too•
Refrigerant piping vs water piping – more complicated• Real-time
heat rejection to outside – less efficient• Melink Super-Hybrid
addresses VRF weaknesses
-
Water & Energy Nexus
• Takes energy to make water (20% of U.S. electricity)• Takes
water to make energy (coal & steam turbines)
INSTEAD, WHY NOT …• Harvest rainwater for cooling (and then
irrigation)• Reduce stormwater to overflow sewer systems• Use solar
PV to power your building
