| Popis: | Using renewable energy sources as a solution for countryâs stable growth needs distinct look in topics of energy production. Agriculture industry is a general industry and it is an energy consumer that can be considered as a topic in this field .Existing a based refrigerator in farm and garden makes optimized harvesting and because it is easy to use sun radiation at these places, it can be used as a source of energy for providing refrigeratorâs energy. One of important needs in refrigerator, is producing continues and stable effect of refrigeration in operator while radiation release is intermittent and variable. By presentation of synthetic cycle of absorbing refrigeration, liquid refrigerant can be stored during radiation, so it can be used in other situations and as a result continues and stable effect of refrigeration can be produced. Considering collectorâs parabolic shape optimized temperature, 119.6°C in generator is available. Optimized temperature of condenser, absorber and operator, in order equals 40, 43.7 and -3.2°C. By selecting 14bars for pressure in generator and condenser and 2bar pressure for operator and absorber, maximum coefficient of operation is 0.178 and rate of heat transfer in generator, condenser, absorber and operator is achieved 19.76, 7.51, 15.77 and 3.51 Kw in order. |
