Hey guys I just saw a news about a solar fridge project developed in Argentina, it doesn't really explain how it works, but it doesn't seem to be using a solar panel but a total different approach, check it out:
Have you seen anything like this before? It says is maintenance free, and can produce 5 kg of ice a day.
The translation is automatic, not by me, so maybe it has some errors.
INTA has a refrigerator that cools down with the Sun
It arose in Cruz del Eje. It is ideal for areas without access to electricity or gas, produces 5 kg of ice per day and would have no cost of maintenance.

It is possible to preserve fresh food without electric power, gas and kerosene. Precisely, arose in Cruz del Eje two prototypes of solar refrigerator projected altogether by the IPAF Pampean Region of INTA, Universidad Nacional de General Sarmiento, the Campesino movement of Cordoba (APENOC), the INTI, SMEs local matalmecanicas and the old step IPEM 306 school. Three of these experimental prototypes will be installed in the coming months in the region.
"For us is a pride from this small village of Zerrezuela, in Cruz del Eje, turns to the first solar prototype for small producers and are present most know solar ice in the Argentina, warned Eduardo Belelli, of the peasant movement of Cordoba. "It is very important that the institutions can converge in the design and manufacture of this prototype, where all contribute our knowledge, to solve a deeply felt in our region need," said the official.
For the researchers of the University of General Sarmiento - since its creation adopted as a principle the link between training, critical research and the search for alternatives-, it is very important to try to field this prototype. Expressed by Sergio Vera and Rodolfo Echarri, of this House of studies: "it is important people that demands it and needs to be the first to put it to the test. For us it is a very valuable contribution to advance our research".
The refrigerator, which uses light energy, works with a parabolic solar collector integrated team, is ideal for areas without access to electricity or gas, produces five kilograms of ice per day and would have no cost of maintenance. The working process will see in INTA exposes pampean region, which will be held from 15 to 17 April in Marcos Ju?rez - C?rdoba-.
The refrigerator operates with a parabolic solar collector integrated team. Cruz del Eje, C?rdoba, presents two pototipos projected altogether by the IPAF Pampean Region of INTA, Universidad Nacional de General Sarmiento, the Campesino movement of Cordoba (APENOC), the INTI, SMEs local matalmecanicas and the old step IPEM 306 school. Three of these experimental prototypes will be installed in the coming months in the region.
"For us it is very valuable to be able to participate in this work table with all these institutions," said Leandro Rueda, the Northwestern Cordoba INTI Tecnico-territorial team. "Here it was shown that, in a joint work, can be efficient use of our resources, time and intelligence, to provide faster responses and solve problems from the installed capacity that each institution has. "That is the challenge: that this experience of Cruz del Eje serves as precedent and motivation to deal with other more complex problems", highlighted the technical of the INTI.
Management process
The articulated work started a year ago and advanced designs and development plans. At this time is in the stage of manufacture of the prototypes, to immediately move to testing and improvements. "The partial results of the manufactured parts are collective results. In no way had been able to generate it institutions separately", said Sergio Justianovich and Marcos Hall, of the IPAF Pampean Region of INTA.
In addition, the researchers stressed that this development is of vital importance since in northwestern Cordoba live nearly 600 producers having as main activity the goat production - meat, milk and milk products-. "Most of these producers has no access to conventional energy networks: the bottled gas is expensive and it is not easy to achieve it, hindering their food preservation".
So far, they added Justianovich and Hall, the refrigerators solar for farmers family available in the Argentina were examples presented in congresses, but by articulating with the researchers of the University it was possible to channel demand for producers. There are currently only experimental prototypes. "We contacted local SMEs so that they can take care of the manufacture and maintenance of refrigeration equipment. "This prototype will adapt very well to areas in which there are bright and without frequent rainy days", explained.
Cold numbers
This prototype, with a capacity of 50 litres, can generate up to five kg of ice daily, since it reaches two to three degrees below zero. "It was intended for the volume of milk remaining in the northern region of Cruz del eje goat producers have," Hall said.
The refrigerator is composed of three parts: a collector, a capacitor and a cold room. One of the features is that is much more friendly with the environment than the conventional refrigerators, since it works with renewable energy. I.e., tools designed to provide benefits that improve the quality of life and the sustainability of production systems without harming the environment, adaptable technologically and that they also add value to the products generated.
Research approaches
The researchers of the Pampean Region IPAF from INTA who participated in this process left two questions: firstly, would build local support structures to make accessible objects allowing to generate improvements in quality of life or the working conditions? And on the other hand, are how to promote platforms to connect continuously in time tracking problems and knowledge that make it possible to develop solutions?
To address them, the researchers used a conceptual model that allows to make visible the map of the technological skills of Cruz del Eje. This model seat bases in focus socio-technical of the technology, as does focus both on artifacts (defined as objects) as in the system of relations that the memorized.
To study such relationships embodied the notion of supporting structure that includes all the agents of the territory that sustain innovation processes. Sergio Justianovich and Marcos Hall argued that, in this approach, "innovation is understood as a social and interactive process involving productive adoption of new knowledge, in the framework of an environment specific and systemic as a factor in improving the quality of life of social relations and productive units".
