Frigerator
Improvement in efficiency and power density of Stirling cycle engines and heat pumps through the reduction of 'dead volume.' For use in solar air-conditioning, food and drug cooling during transportation and storage, waste heat conversion to energy, storage of daytime solar power and reconversion to power at night or cloudy days.
Solutions
Solar Air Conditioning Heat Pump with Minimized Dead Volume
This design is based on the dual Stirling cycle. This solution aims to use solar thermal energy to run this cycle without electrical input during periods of direct sunlight. This approach uses the regenerator matrix of the Stirling cycle as the displacer in a manner that allows all working fluid to be purged from the interstices of the regenerator at the end of each cycle, thereby increasing the efficiency and power density of the device, and offering more affordable cooling.
