hello Sir,
I am Suresh Kumar student of Mechanical Engineering,I have need of material on pedal power zeolite refrigerator as i am going to make my final year project on this. So please help me.

The PEDAL POWERED ZEOLITE VACUUM REFRIGARATOR project was the development and the introduction of a new
type of technology for the refrigeration systems based on the innovative zeolite/(vacuum) principle. The advantage of this new
and environmental friendly cooling system is the use of natural elements (no refrigeration gas required). Moreover, the new
refrigerators offer an increased mobility due to their independency from the power grid. The goal behind the project was the
development of alternative systems that are complementary to the actual refrigeration systems, such as the compressor system
and carbon dioxide snow.. The new refrigeration system developed by Domestic generates cooling capacity by using two
natural elements (instead of cooling gases): Zeolite and vacuum. Zeolite is a mineral that has the property to adsorb vacuum
vapor while releasing heat at the same time. It represents an interesting element to store energy and to transform it in heating or
cooling agents. Due to its capacity of working independently from the power source for a specific period of time, the new
technology suits mostly for the transport of food and other perishables. It could also be used in the medical field (transport of
vaccines etc.). The energy stored in the zeolite elements is used to keep the desired temperature in the refrigerators during the
transport time. During the implementation of the project, Domestic has built several transport and medical containers using
zeolite/vacuum technology, demonstrating that the new system is environmentally friendly and technically viable. Due to
increased energy consumption, compared with the conventional refrigerators during the regeneration phased, the Zeolite
systems are economically feasible under specific circumstances.

The purpose of the bicycle powered refrigerator is to allow someone to take a bike trip and keep their food or drink cold. This project can be used for poor neighborhood of Africa or Asia where electricity is still a distant thing . Moreover it can be extended to more useful device with the help of windmill or flowing water . If its pedals joined with the turbine revolving using wind or water, we can use this refrigerator as a automatic machine . This project idea is for student of mechanical , electrical and physics students.

Concept :

When we pump out gases from the water box in the refrigerator by paddling a bicycle , we creates low pressure area inside the box, due to this low pressure ,water starts evaporating, and for that evaporation it needs heat from the surrounding which is our refrigerator.In that way it cools our refrigerator.

Steam is generated in the process of evaporation which later been absorbed by Zeolite as shown in video . Absorption of steam is a property of zeolite that's why we use it in this experiment.

What are Zeolites ?

Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents.An example mineral formula is: Na2Al2Si3O10·2H2O, the formula for natrolite.The major producers in 2010 were China, South Korea, Japan , Jordan , Turkey ,Slovakia and United States. The ready availability of zeolite-rich rock at low cost and the shortage of competing minerals and rocks are probably the most important factors for its large-scale use. You can purchase it from any mineral supplier in your city. Just google it with your city name.
