| Solar collector is a water heater that uses solar power as a source of heating. The sun as a heat source is needed is a source of energy is available continuously, therefore as one of the alternative energy solar light and heat must be used. And now the hot water demand will increase, both for bathing and washing. To obtain solar water heaters are economical, system optimization analysis on the thermal water heating systems are indispensable for the production cost can be reduced, especially collectors. So get a cheap price in the manufacture of heating systems and hot water to get the maximum. The volume of this collector is 25 liters. Optimization calculation used is to use linear programming, the function of minimizing the cost of manufacture of flat plate solar collector types. Barriers are used to the heat generated by solar collectors. Linear program optimization calculations with the aid of lindo program. From the calculation results of optimization of thermal systems by comparing the prices collectors of type X, the price collectors are facing the sun is more expensive than the price collector to the sun. Price optimum solar collector type X is Rp Rp.3.465.000.00 while the price collectors are used in the final task is Rp.3.317.500.00.Hal This can occur due to the position of the sun-facing solar collector is more optimal than the position of the solar collector to the sun. But of the entire water heating system used in this thesis with the cheaper price of Rp.8.688.000.00, while the water heater type X Rp.11.550.000.00. |
