PEDAL POWERED ZEOLITE REFRIGERATOR PDF

27 Jun We are going through the process of testing of equipments which is to be used in the manufacturing of Pedal Powered Zeolite Refrigeration. Pedal Powered Zeolite (Vacuum) Refrigerator. • The project is based on vacuum principle and adsorption our project: • The development of. 16 Nov This project seem very interesting. Pedal-Powered (Vacuum) Zeolite Refrigerator – YouTube any tried it before? i was just wondering if i can.

For cooling, continue pedaling is required.

The limitations that they are working on include the low COP values, poor heat and mass transfer problem that poses a bottleneck to prevent the improvements of adsorption refrigeration technique, intermittently working principles, high technology requirement and special designs to maintain high vacuum. Initially we built the Pecal unit of GI-sheet, without internal support. Thus, adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface.

The Hurdles Once the design was put on paper, the real challenge lay in actualizing it with instruments, apparatus and raw materials. Follow us facebook twitter instagram youtube.

In general, one can achieve constant temperatures of Celsius for 1 day with only 10min of pedaling. Pedal Power Zeolite Refrigeration.

With further modification and up gradation, Narendra hopes that the refrigerator could be used in remote areas with lesser access to power. It is a remarkable technological offering that zeilite made our lives a lot cooler.

Somehow we got the Zeolite retail seller address from Bengaluru, because most of the sellers we contacted were whole sellers who did their business in tons but our requirement was in few kgs only.

After only about 10 min refrigeerator pedaling, the valve to the vacuum pump can be shut off, and the zeolite container line opened. There were other challenges too and corresponding modifications done. 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. Problems Identified Time consuming Leakage problem through pipes Improper working of Piston Proper lubrication is required This system only works when vacuum is created.

T echnology is indeed like a two-sided coin. The adsorbing phase is the adsorbent, and the material concentrated or adsorbed at the surface of that phase is the adsorbate. Click here to access the Project Fefrigerator, and view their refrigeratot here. There were also some concerns related to the use of methanol, since it is toxic.

We live pedzl the North geographical region of Karnataka, where temperature is usually high in summer degrees celsius. Take the refrigerator, for example. An alternate adsorbent-adsorbate pair selection can easily solve this problem.

TBI Innovations: The Mechanical Fridge – Freezing Environmental Damage

Ipsita Sarkar is a freelance writer. In the designed refrigerator, zeolite is the adsorbent and methanol can be treated as refrigerant. The refrigerant used, methanol, is environmental friendly since it is not a hazardous substance. The idea started off as their topic for the final year project. While we can go gung-ho about technological progress and how it has simplified our lives, we can also talk about in the same breath about the adverse effects of technology, particularly on the environment.

This process creates a film of the adsorbate methanol on the surface of the adsorbant zeolite. 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.

Narendra tells us proudly:. The continued pedalling will ensure that the water freezes as it continues to refriherator. Even with exams nearing and project deadlines looming large over their heads, they travelled from store to store and went that extra mile. Obviously, it was not just the marks that the design could fetch, it was also the delightful revolution that this could bring about, something that Narendra and his reffrigerator batch mates, Anil and Murthy were very proud about — of making the refrigerator an affordable and economical choice and not just a luxurious one among even the lower income population.

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.

Back in college we used to have our practicals in workshops, where podered used to get exhausted by the time we finished. Our Project Guide was happy to see the results and appreciated our hard work. This was what motivated the third year Engineering student from BEC College, Bagalkot, Karnataka, Narendra Patil to come up zeolige this interesting model of a refrigerator. Some of their efforts were wasted too as the few apparatus they had bought earlier were hydraulic valves and not pneumatic valves.
