Advanced Space Heating
>Condensing Furnaces have a waste water discharge ()
>Optional humidifiers () have a need for a fresh (ideally purified) water supply
─ Avoid mineral deposits that reduce reliability and life while increasing maintenance costs
>Two birds with one stone?
66
Advanced Humidifier & Heat Recovery Current GTI SMP Project
>Integrated heat recovery and humidifier for home furnaces
>Captures waste heat and (pure) water from natural gas flue gas combustion
> No external water supply
>Energy savings: 95%+ efficiency
>Greater indoor comfort & savings
>Improved humidifier reliability without bacteria & deposit and dust issues
77
GTI High Efficiency Gas Packaged Air Conditioner (PAC) Project
>Condensing Furnace Specification dealing with
─ Technical issues of secondary heat exchanger & condensate
─ Economic issues of first cost and net operating cost savings
>Prototype Field Test over the 2010-2011 winter
88
Natural Gas Cooling
> Larger absorption or engine-driven chillers provide energy savings in high electric markets
─ Offset peak summer electric demand – potential customer and utility savings
> Smaller options─ Small absorption units (e.g., Robur)
─ Engine-driven heat pumps…build on Japanese products
> Integration with solar thermal and waste heat recovery/CHP

HOT Water ProjectTechnical Objective
> Hybrid Optimized Tankless
(HOT) Water Heater
> Develop prototype and test a
hybrid water heater with best
features of tankless and tank-
type water heater
> Optimize performance,
efficiency, and cost
> Advanced control strategies
and thermal management

Low-Power Gas ValveNew SMP Project
> Industry Need: Deal with the pilot light in a responsible way that does not over burden customers before it is dealt with by others
>Value to the Industry
>Objective: Develop a safe and reliable low power gas valve that can run battery-operated over the 10-year life of a water heater
Non-Powered Powered
Pilot light consumes up to 17% of the total annual energy of a non-powered gas water heater, eliminating the pilot light could provide significant energy savings

Smart Grid
> Electric vs. Natural Gas vs. Energy Grid?─ How should we use natural gas in
a carbon-constrained future?─ Who will manage energy?
> Customers?> Utilities?> Google?
> What value can be created with Smart Grid systems?─ For gas customers─ Energy savings?─ CO2 reductions?
