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.
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.
