Research on Microclimate Cooling in protective clothing is not a new topic. Yet we are not able to provide cooling to the health care workers. In this research contribution I try to give some information on where the problems are.
Health personnel, entering the suit through the door made of transparent material. Gloves and boots standing, the door is sealed. The door contains an "opener" that is used to exit the "cocoon".
With contaminated suit, you enter the "cocoon" whic
The Ebola Community Action Room is moving fast! Through Onu and others with networks in West Africa, we have established contact with a great group of community activists with many community volunteers throughout Liberia. This is true citizen-to-citi
Backpack Mobile Cooling System is designed to be worn under PPE to provide 2+hours of cooling. The system pumps ice chilled water though a hooded vest that covers the chest and back as well as the neck and head. This system circulates the same decont
Update: We've submitted our expression of interest to USAID!
Update: We setup a basic test to show the viability of rapid, on-demand recharging using "instant cold pack" ingredients. Our Phase Change Packs can be recharged in 10 mins using ammoni
thanks for updating the post. I still wait for a quantitative description of the problem (How hot is the environment really, how active are the workers) and on experiments. I am quite sure, that someone makes this, but all people I asked do not know about this. So we will probably learn this in a few month.
And to do measurements ourself to evaluate and improve is difficult without a climate chamber and other tools. And again, I would not even know how hot I shall make the climate for the tests. The resources of USAID appear so limited, that they have no time to give us feedback by experts. And if I try to help you, this takes even more from the limited time, I have for making and proposing own ideas. So, I am sorry, but I cannot help you as much as I would like to.
it is the same like sweating. If water evaportates it requires energy, the latent heat of evaporation. This energy is taken from the liquid and cools it.
The same works with liquid cryogenic gas. Just leave the bottle open, the liquid evaporates and cools the liquid. We do this routinely in laboratories. But typically not with liquid air, but with liquid nitrogen. Liquid air is not so easy and safe to handle as liquid nitrogen, but you can get and use it, if needed.
