RE: [RC] Equipedic and Research on Phase Change Material - Libby & Quentin Llop DVM
Candace,
Endurance riders are very familiar
with this physical principal and use it often. We sponge water from puddles on
our horses, it changes to water vapor -taking heat from the horse (evaporative
cooling). It then rises through the atmosphere until it reaches the lift
condensation level, where it gives up its heat, turns back into liquid (clouds)
and completes the cycle by raining back into the
puddles.
Where do your phase changing beads
give up the latent heat of fusion and turn back into solid beads? And how far is
that from the horses back? Libby (didn't take
physics in high school but took a second major in meteorology at
university)

Hi All,
For those of you who like the scientific and reports etc
- a short search on the internet produced the info below info
on phase change materials:
For those who hate the scientific let me explain what I
understand is the concept behind phase change material. It's based on
physics (yikes! - I took physics in high school and the best thing about
physics was the wonderful guys that sat beside and behind me - what a fun
class - never got the physics part - LOL). Well anyway when you drop an
ice cube in water it turns the water cold. You think it turns cold
because the ice is cold and therefore makes the water cold - right?
Nope, wrong. When you put the ice in the water it draws the heat
from the water to melt the ice. When the heat is removed from the water
it becomes cooler. Voila (took French too) the concept - the phase
change material in the Equipedic Pad draws the heat from the horse's back and
therefore the back is cooler. It works.
