Phase change materials (PCM) have the capacity
to reduce heating, ventilation and air conditioning (HVAC) costs by a number of
different mechanisms, including:
eliminating air conditioning costs by storing nighttime coolness for use
during the day, eliminating heating costs by storing daytime warmth for use
during the night, and load-shifting of electricity through thermal
storage. Well-designed strategies and
utilization of phase change materials could easily reduce HVAC-related carbon
dioxide emissions by more than 25% from current levels. It is anticipated that these reductions in
emissions can be achieved while saving consumers money and creating new markets
for agricultural commodities.
This presentation is on the latent heat
properties of fat and oil derivatives with an emphasis on HVAC
applications. The latent heat
properties of mixtures are described from a fundamental perspective. After identifying target derivatives and
compositions, strategies are presented through which these compositions can be
achieved complete with experimental verification of these synthesis
routes. Finally, known and new devices
for using these PCM chemicals are described.
Preliminary economic analyses indicate that fat and oil based PCM
chemicals can be produced for less than half the price of paraffin PCM products
currently produced from crude oil.
These new markets could provide a much-needed influx of billions of
dollars into animal fat and vegetable oil markets.
