Since Willis Carrier invented air conditioning technology to cools humans in 1902, the improvements in this space have been marginal. Air conditioner or AC that we use in our homes not only has poor energy efficiency, but also are of a little to no use in many niche applications. For e.g. Hot Flashes, Cooling outdoors, Multiple Sclerosis(MS), Rehabilitation of fire fighters etc. We need to change the very core of how we cool people and that's what Pride Chill does.
The idea is to just cool the breathed air instead of cooling the whole room. The advantages are:
- Fast Cooling - It cools the core of body really fast because it directly cools inside of a human body. This makes Pride Chill a really good fit for Hot flashes because they typically last 1-2 minutes so something instantaneous is required to provide comfort.
- Prioritizes Brain Cooling - Brain is the most important organ of human body and cooling the brain creates immense cooling sensation. This technology very quickly provides cooling to the brain.
- Energy Efficiency - It uses 1/3rd of the energy used by an AC.
So what happens when you cool the breathed air?
There is cooling mechanism in humans which is known as Nasal cooling or Respiratory cooling. It accounts for upto 30% of body's cooling load. Nasal cavity is an extremely efficient heat exchanger that transfers heat from blood to air. This blood then flows in the whole body and cools each and every part. Right after leaving the nose, blood enters the brain and therefore prioritizes cooling of brain.
Sounds simple and a no-brainer? Why didn't someone already do that?
In order to utilize the power of this idea and make it a practical product, the gadget needs to be compact and light. Think of it like, would you want to roll a big giant machine with you? After years of hard-work, I was able to develop a novel technology (patent pending) that can significantly cool the breathed air (by 10-15°C). The current stage of technology, Version 2, is developed enough to be practically used by women experiencing hot flashes. Menopause or Hot Flashes is a big problem and there are almost no non-drug solutions that significantly helps women in this phase of their life.
Are there other applications of nasal cooling?
There are other products in market that target the nasal cooling mechanism but have very different applications and are way too bulky (which is not a problem in their markets). For e.g. Quick Cool and Rhino Chill, they are used in cases of Cardiac Arrest or Stroke.
