Evaluation of decentralized ventilation system with heat recovery

Abstract: Humans spend 90% of their times indoors, and maintaining a pleasant indoor environment is essential. Factors like human behaviour, combustion sources, cleaning supplies, affect the indoor environment, which could potentially affect the human health.the most common answer to controlling the indoor environment is a good HVAC system. Ventilation systems with supply and exhaust are not standard in residential houses, natural ventilation with exhaust ducts or just mechanical exhaust system is conventional among the residential sectors. A cost-effective and an energy-efficient alternative could be a “Decentralized ventilation system” This report aims to provide knowledge of such innovation in the field of HVAC, to evaluate the performance of a decentralized ventilation window unit system. The results aimed to declare the performance of a window unit decentralized ventilation system developed by SMARTVENT. The tests are done according to the standards that have to be followed, and the ventilation unit has performed up to those standards in various airflows. Nevertheless, it needs to be tested further to be released in the market. A separate control system must be built for this unit to do any further testings.
