Antibacterial Side By Side Refrigerator

Antibacterial properties can be obtained by the use of granules containing nanoparticles. The “antibacterial activity” was evaluated by ISIRI 10900 standard “Measurement of antibacterial activity on plastics and other non-porous surfaces. Antibacterial activity is an indicator of the product ability to eliminate bacteria. It is obtained by comparison of bacteria number present on control and nanometric samples after 24 hours’ exposure. According to standard, when the antibacterial activity of the product is between 2 and 3, the effectiveness is good. If antibacterial activity is greater than 3, the effectiveness is intense and strong.

Nowadays, refrigerators exist in all kitchens especially in developed countries. The main application of these household appliances are postponing spoilage of foodstuffs and increasing food storage time. In addition to the refrigerators, the freezers are other kinds of appliances which have less temperature inside and provide more storage time in comparison with the refrigerators.  A refrigerator maintains a temperature a few degrees above the freezing point of water (3-5 oC), but freezer maintains a temperature below the freezing point of water. In general, it can be said that the refrigerators and freezer have become one of the main requirement in all kitchens. To increase useful space for food storage and decrease space occupied by these applicants, a variety of refrigerators and freezers models. Side by side is one of the popular model which not only do they have sufficient food storage space but also they occupy a small space in kitchens. Another issue that is being considered today in the manufacturing of refrigerators is the reduction of bacteria presence on their inside wall leading to less food spoilage and maintaining food quality. The body of the glacier is susceptible to accumulation of bacteria due to seams and corners, resulting in unpleasant odor and discoloration. To this end, refrigerators with antibacterial inside wall, that nanotechnology have been used in their making are developed.
