Pedal Powered Zeolite (Vacuum) Refrigerator. which provides it with increased mobility. • The new refrigerator created is independent of power grid. Pedal-Powered (Vacuum) Zeolite Refrigerator. The refrigerator works by creating a vacuum in a system of 2 chambers to drive a thermodynamic reaction (boiling. 16 Nov Pedal-Powered (Vacuum) Zeolite Refrigerator – YouTube any tried it before? i was just wondering if i can replace the Zeolite to just simple.

Narendra tells us proudly:. There is a baseboard unit that includes a tyre pump, a heat exchanger, a pump, pump valves, and a metering valve, pedal powered zeolite refrigerator well as a hand crank. In the designed refrigerator, zeolite is the adsorbent and methanol can be treated as refrigrator.

It could be used in medical camps again in rural areas for preserving vaccines and drugs and as water cooling units.

T echnology is indeed like a two-sided coin. For cooling, continue pedaling is required.

pedal powered zeolite refrigerator It forces hot pressurised air through a heat exchange which returns the air to near-ambient temperature. The major items required were not available in their district. The adsorbing phase is the adsorbent, and the material concentrated or adsorbed at the surface of that phase is the adsorbate.

One, that of necessity and two, that of the environmental degradation that it can cause by consuming power and emitting CFCs chlorofluorocarbons into the ozone layer, thus depleting it and leading to global warming.

In general, one can achieve constant temperatures of Celsius for 1 day with only 10min of pedaling. This is a real way to cool for cheap. Thus, adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. Later we chose copper sheet with internal pedal powered zeolite refrigerator.

By logging in, you agree to our terms and conditions and privacy policy. Victor Papanek described this in his book Design for the real world: With further modification and up gradation, Narendra hopes pedal powered zeolite refrigerator the refrigerator could be used in remote areas with lesser access to power.

Clearly, what is required is a neutral zone wherein a refrigerator is available to all, yet with minimal adverse environmental impact. The Hurdles Once the design was put on paper, the real challenge lay in actualizing it with instruments, apparatus and raw materials.


Since this problem was solved, we have begun doing re- search into substituting a sandwich panel made of two outer layers of used newspapers and a core of dried native leaves for the styrofoam.

It not only runs without electricity but can also be available to the poor as an inexpensive and necessary utility option and no longer as pedal powered zeolite refrigerator luxury one meant only for those with large pockets.

This process creates a film of the adsorbate methanol on the surface of the adsorbant zeolite. An alternate adsorbent-adsorbate pair selection can easily solve this problem. Pedal Power Zeolite Refrigeration. Yet, we chose methanol replacing water because of failure in attainment of desired vacuum point to start the phase transformation which leads to adsorption phenomena.

Other modular cubes can be added. There were other challenges too and corresponding modifications done. Interestingly, another technological accomplishment in the arena of social networking, YouTube, helped the trio in their cause. Back in college we used to have our practicals in workshops, where we used to get exhausted by pedal powered zeolite refrigerator time we finished.

Project Ideas: Pedal powered refrigerator

Ipsita Sarkar is a freelance writer. Problems Identified Time consuming Leakage problem through pipes Improper working of Piston Proper lubrication is required This system pedal powered zeolite refrigerator works when vacuum is created. Have you added Founders Circuit app to your account?

Hence I decided to choose refrigeration as a field for our final year project, which will be an alternative to the conventionally used refrigerator, a project in which simplification of present tech is involved to get cooler water, with less power consumption so that a pedal powered zeolite refrigerator man can have an access to it.

We developed a hand-cranked, pedal powered zeolite refrigerator produce cooler. Only logged in users can reply. There pedal powered zeolite refrigerator research going on the solar powered adsorption refrigeration. Response and Road Ahead The model completed, there were felicitations and applause from every corner. Narendra Patil, a third year engineering student from Karnataka and his fellow mates tapped the positive side of technology and their engineering knowledge, to come up with a unique model of an eco-friendly refrigerator.

We live in the North geographical region of Karnataka, where temperature is usually high in summer degrees celsius. There were also some concerns related to the use of methanol, since it is toxic. There are also many other essential purposes that such refrigerators could be utilized for apart from storing food, as Narendra points out.

The reason behind its cost efficiency is its zero power consumption and no requirement of fossil fuels to burn the planet in the process of cooling. The mechanical work of pedalling the cycle has also been done and is contend to the piston which is used for the process.

Even ice cubes can be made, and one cool advantage of this system is that the hotter it is outside, the more cold you can generate. We did this prototype pedal powered zeolite refrigerator with our UG capabilities and available sources within our reach and we can assure you that with more dedicationresearch and better design we can build a sustainable model. And yet we have to do a lot of testing over the equipments and machinery for the complete manufacturing of our project Pedal Powered Zeolite Refrigeration.

Somehow we got the Zeolite retail seller address from Bengaluru, because most of the sellers we contacted were refrgerator sellers who did their business in tons but our requirement was in few kgs only. Subscribe To Posts Atom. It is a remarkable technological offering that has pedal powered zeolite refrigerator our lives a lot cooler.

Limitations While confident about the pros of his refrigerator model, Narendra and his team simultaneously hope to address the cons of the model as well, to achieve pwoered best possible efficiency.

The idea pedal powered zeolite refrigerator off as their topic for the final year project. Click here to access the Project Report, and view their video here.

This was what motivated the third year Engineering student from BEC Powerex, Bagalkot, Karnataka, Narendra Patil to come up with this interesting model of a refrigerator.
