Abstract
A solar-powered air conditioning system including an energy-storage medium made of a mixture of 5%-20% glycerin, 2.5%-10% alcohol and water in a thermally insulated container is disclosed. While frozen, the said energy storage medium becomes slurry of thin sheets of ice dispersed in liquid, which will not damage the container and the heat-exchange pipes. The system uses a solar photovoltaic panel to directly drive a vapor-compression refrigeration unit to freeze the said energy storage medium. A ventilation system forces air through a heat-exchange coil in the said energy-storage medium, to generate chilled air to cool the space. In the absence of sunlight, the energy-storage medium can keep frozen for days. With or without sunlight, the flowing air chilled by the frozen energy-storage medium continues to cool the room or the entire building.
