The refrigerator works by creating a vacuum in a 2-chamber system to drive a thermodynamic reaction (boiling methanol) at room temperature. The drop in methanol vapor pressure causes methanol to boil. To do this, methanol must capture the heat of a system (the inside of the refrigerator). After only about 10 minutes of pedaling, the valve to the vacuum pump can be turned off, and the line of zeolite vessel open. The zeolite are common absorbers based on aluminum silicates and swell up to 30% of their mass with water. The zeolite then absorbs the vapor produced by the boiling of the methanol and for the liquid methanol to remain in equilibrium with the vapor phase; It should continue boiling (for up to one day). In general, constant temperatures of 0-6 Celsius can be reached for 1 day with only 10min pedaling. Now this is a real way to freshen up for cheap. Even ice cubes can be made and one advantage of this system is that the hotter it is outside, the colder it can be generated.
The ZEOLITE PEDAL POWERED VACUUM REFRIGERATOR was the development and introduction of a new type of technology for cooling systems based on the innovative zeolite / vacuum principle. The advantage of this new cooling system and respectful to the environment is the use of natural elements (it does not require refrigerant gas). In addition, new refrigerators offer greater mobility due to their independence from the electricity grid. The objective of the project was the development of alternative systems complementary to existing refrigeration systems, such as the compressor system and carbon dioxide snow. The new refrigeration system developed by Domestic generates cooling capacity through the use of two natural elements Gases: Zeolite and vacuum. Zeolite is a mineral that has the property of adsorbing the vacuum vapor while releasing heat at the same time. It represents an interesting element to store energy and transform it into heating or cooling agents. Due to its ability to work independently of the power source for a specific period of time, the new technology is mainly adapted to the transport of food and other perishable products. It could also be used in the medical field (transport of vaccines, etc.). The energy stored in the zeolite elements is used to maintain the desired temperature in the refrigerators during the transport time. During the implementation of the project, Domestic has built several transport and medicinal containers using zeolite / vacuum technology, demonstrating that the new system is environmentally friendly and technically feasible. Due to increased energy consumption, compared to conventional refrigerators during the regeneration phase, Zeolite systems are economically viable under specific circumstances.
