NEW DEVICE DESIGNED TO RECOVER HEAT AND PREVENT HOME POLLUTION
THE EQUIPMENT HAS THE ADVANTAGE OF USING LOW COST ELEMENTS IN ITS MANUFACTURE COMPARED TO THE EXISTING ONES WORLDWIDE. IT IS CURRENTLY IN THE PROTOTYPE STAGE.

"Low cost heat recovery" is called the technology designed by experts from the Kipus Engineering Systems Center of our University to conserve heat and reduce significantly home pollution.
The operation of this type of devices, that allow ventilation with minimum energy loss, consists in that the exhaust air transfers its heat to the entering air, thanks to a technology called Heat Pipe.
These devices, even though they are well known and used around the world, have had a low penetration in the home market, due to their high costs and the low need for solutions of this type in developed countries, given their low levels of indoor air pollution.
The unit is composed of elements that are easy to get, like two Heat Pipe cooling units commonly used in personal computer processors. Each cooling unit has an approximate cost of US$20, which adds to the costs of a particulate matter filter, a casing and a transformer. It covers about 100 square meters and the power consumption does not exceed 6 watts, equivalent to a Led bulb.
Carlos Torres, director of the Kipus Engineering Systems Center, said that Chile has encouraged the use of devices that work producing combustion within the home, such as kerosene or gas heaters, which have become an alternative for firewood. However the economy and performance of those equipments is countered by the gases generated within the house, involving the generation of pollutants such as nitrous oxide (NOx), carbon monoxide, volatile organic compounds and particulate matter.
"Today, the discussion about the environmental decontamination plans has focused on the prohibition of the use of firewood, but it has overlooked the nature of it as a renewable source and it has encouraged the use of alternatives that contribute to indoor air pollution," he said.
Torres noted that, "the development and use of technologies for efficient and clean use of wood has not been promoted, nor the assurance of good indoor air quality”. He added that "with this technology and the other ones developed at Kipus we intend to contribute to improving the quality of life".
What has been achieved by the aforementioned Center is part of its activities to promote energy efficiency in homes and the use of alternative energies.
