NEW SOLUTION REFRIGERATORS FOR FRUITS AND VEGETABLES THAT USE SOLAR ENERGY TO ACHIEVE POSITIVE TEMPERATURES
Yanko Aleksandrov
Abstract: Here are reviewed new solutions for fruits and vegetables that use solar energy in order to achieve positive temperatures. Furthermore, the main aspects of the basic requirements for their implementation are taken into consideration. Three typical solutions with inventive step of the author are reviewed. These are:
● BG63644 (B1). Built-up refrigeration chamber (Aleksandrov, 2002). The triangular panels 5, situated on the walls and the roof of the refrigerator chamber can be also made of transparent structures, whereas the chamber is directly situated on the respective terrain over a ribbed plate; the ribs form ventilation channels.
● BG № 111651/09.12.2013 г. Moveable cold storage chamber for positive temperature. BG111651 (A) (Aleksandrov, 2013a.) Transparent angular two-plane elements are used for the direct lighting of the fl oor and the ceiling of the refrigeration chamber, the penetration of solar beams is directed by sunblinds, which are controlled by sensors.
● BG № 111658/17.12.2013. System for solar heating of cooling chamber with positive temperatures. BG111658 (A).(Aleksandrov, 2013b) Solar water collectors are used for heating and hot water supply to meet various demands, e.g. to
cover the technical needs (e.g. washing of root fruit and vegetables, etc.)
In extreme situations, the refrigerators for fruits and vegetables which operated under positive temperatures can be used for various other purposes, e.g. medical purposes – as premises for the situation of operating rooms. The transparent elements will allow the penetration of natural light, whereas water collectors will provide hot water for medical purposes. The application of
tension membranes and tensegrity structures as a way of executing protective screens on refrigerators for fruits and vegetables under other harmful external conditions – acid rain, falling volcanic ash, formations of smog and others is also described.
