Frigerator
Frigerator develops advanced Stirling cycle engines and heat pump technologies with a focus on significantly improving efficiency and power density through the reduction of “dead volume.” The technology is designed for applications including solar-driven air conditioning, food and pharmaceutical cooling during transportation and storage, waste-heat-to-energy conversion, and thermal energy storage—enabling the capture of daytime solar energy and its reconversion to power during nighttime or cloudy conditions.
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.
