Personal ‘AC unit’ worn under clothes to be launched soon

At at around four inches long,a little longer than a pen,and two inches wide,the personal air-conditioning unit weighs around 3.5 ounces,equivalent to around 40 one pence pieces,’The Daily Telegraph’ reported.

The unit can be sewn into the fabric of clothing,such as the uniforms of firefighters or soldiers,or the overalls of a racing driver,without causing discomfort.

As the temperature rises,hot air will be sucked into the thin steel case to be cooled by a micro-compressor and then propelled out through a network of thin tubes in the clothing,say its developers.

Joao Carlos Brega,global president of Embraco,said the firm has already discussed the invention with Formula 1 teams,armies and firefighting services.

Embraco also hopes the product will be used in paramedics’ blankets to help reduce bleeding,to refrigerate organs being transported for use in transplants and in LCD screens that sometimes overheat.

Brega said the company would not,however,be sold as a stand-alone air-conditioning unit for shoppers to attach to their own clothes. “When you begin to approach the customer for the solution and not the product,he pays more for it.”
