Amazing world now you can buy Made in China AC Air-Conditioned Vests Keep Chinese Factory Workers Cool

In China and other countries having high temperature round the year,worker are unable to show their full abilities.This  thing really effect the company's production and hence country will  also.In Order to overcome the situation,Chinese engineers  were working on special vest which can help worker,even in the hotter part of factory.Now someday ago,they got success to make vest which will give cooling to worker during their work.They named it AC VEST,which has the ability to decrease the temperature about 20 degrees.

''It means that  at 40'C when someone wearing the vest  then he feels like as if it were 20 'C''

''Wang Yan, a 4 year old business man in Nantong,Jiangsu province,Invented the Vest.He devised as it if temperature of atmosphere  is 40 degrees then  Vest can lower the temperature,of human skin to about 20 degrees.
Wang opened a factory to make the vests,and he has  sold about 4,000 of them in the last three months-40 percent more than last year.

Mechanism:

•  The Vest is made of impermeable fabric to lock in the cool air.Cool air is distributed through small tubes with tiny holes that are inside the vest.
• Compressed air is delivered into the vortex tube,swirls quickly and forms a funneled airflow,like a tornado,causing hot air to sink and cool air to float.
• Then cool air stream is distributed through the vest wang originally wrapped the cool air tubes and around him when he worked.He later managed to integrate the tube into vest.
• Inventer  then continued renovating the vest to make it cooler.
• The valves on each side of the tube,One control the inflow of compressed air and the other controls the cool air output with which the user can regulate the temperature

''Normally when the temperature is around 35 degrees C ,the vest can lower it to about 25 c in 30 second''
