The intention in this work was to generate and store adequate energy to power a natural ambient room cooling system. A major problem that the automatic air-conditioning industry is facing today has to do with too much power consumption in that the heat and ventilation air conditioning (HVAC) systems are currently using about 50% of all produced electricity. The latter also does not consider the peak time of use, where the desired ambient temperature of an air-conditioned room is greatly affected by the activities of the occupants at a given time. As part of the power management system, the concept of charging a battery to full capacity is explored of exploiting the excess energy available surrounding a cooking pot after, even after the heat source is removed. Thermoelectricity (TE) is used to capture wasted heat from the pot, and the reclaimed thermal energy is optimized for conversion into the electrical power. This is in short what I did. These are my results in summary.
Cooling and ventilation systems play an important role in human occupied spaces. However, cooling using reversible air conditioners systems pollutes the environment and consumes a significant amount of energy. With global warming that experiences our environment, the large consumption of electrical energy and the operating instructions for reversible air conditioners, there is a need to find alternatives to those cooling systems. Hence this research project aims to investigate an air storage system, a microsystem reversible ventilation system using natural atmospheric air (renewable energy) for cooling at low consumption of energy. For the variation of the temperature range of comfort due to thermal heat produces by occupants, equipment and environment, an optimal transient automatic regulation of air flow as to be design in order to maintain the temperature of comfort in occupied spaces during peak hours.
