A portable and hybrid solar-powered

A portable and hybrid solar-powered membrane distillation (SPMD) system has been designed and developed. The current study was conducted at College of Engineering, King Saud University, Riyadh – Saudi Arabia. The hybrid system works on the zero energy concept which does not require external energy, and only utilizes solar energy for its operation. The Memsys V-MEMD unit has been successfully integrated with the solar-thermal collector and the solar-PV system. In this study, a small-scale test based on one-day operation of the system was conducted in manual mode. The heat pump was operated to increase the distillate production by preheating the brackish water before fed into Memsys V-MEMD unit. The test results showed that the portable SPMD system ran perfectly by only utilizing solar energy and without external energy from the grid. The average distillate output rate was approximately 11.53 L/h (Test on 18 Feb 2013) with the maximum level of 15.94 L/h (at noon time). The total volume of distillate output on that day was about 70 L with an approximate conductivity of 4.7 μS/cm. This distillate volume can be considered as a low output. However, due to its modularity, the capacity of the system can be easily increased to meet the water demand by increasing the number of the Memsys “effect stages”. The magnitude of the distillate flux was in the range of 1.5–2.6 L/m2 h, which is comparable to other research studies. Other tests were also conducted to study the performance of the thermal collector. The solar energy converting efficiency (in percentage) of the thermal collector was quite low. The mean value of the solar energy converting efficiency from the two tests was approximately 33.6%.

Refining System (SPMD) portable solar cell and hybrid design. And the present study conducted at the College of Engineering. Pervaiz said the king Oud University, Riyadh - Saudi Arabia hybrid system operates a zero energy concept which does not require external power. And use of solar energy for operation only unit Memsys V-MEMD has been successfully integrated with collector solar thermal and solar systems. PV in this study Small test based on one day of operations performed in manual mode operation, the heat pump to increase production, desalination of brackish water before entering into the unit Memsys V-MEMD test results show that the system SPMD Portable runs. perfectly Using only solar energy and an external energy from the grid refined average yield of about 11.53 liters / hour (tested on 18 February 2556) with the highest level of 15.94 L / h (noon) volume. Total refining output was estimated at 70 liters with the estimate of a 4.7 μ s / cm volume distillation is regarded as a low yield , however. Because the master System capacity can be easily increased to meet the demand for water. By increasing the number of Memsys "of the" size of the flux is refined in the 1.5-2.6 L / m2 h, which is comparable to other research studies are also conducted other tests to determine the effectiveness of the heat. Solar energy conversion efficiency (As a percentage) of a relatively low heat an average conversion efficiency of solar energy from the second test is about 33.6%.

Membrane solar distillation (SPMD) portable systems and hybrid designed and developed the current study was conducted at the College of Engineering, King Saud University, Riyadh - Saudi Arabia system hybrid that runs on the concept. zero energy, which does not require external power, and only use solar energy for the operation of the unit Memsys V-MEMD has been successfully integrated with solar thermal and solar systems. PV in this study are small-scale test is based on the one day the system has operated in manual mode, the heat pump has been taken to increase the production of refined warm brackish water before entering. units Memsys V-MEMD test results show that the system SPMD Portable runs perfectly, especially using solar power and energy from the outside, without the tables rates average export refinery at about 11.53 liters /. h (test on February 18, 2013) with the highest level of 15.94 liters / hour (at noon), the total volume of exports of refined in those days was about 70 L to import about 4.7 microseconds / cm refining volume. this is regarded as a low yield , but the master of the system capacity can be increased easily to meet the water requirements by increasing the number of Memsys "effective steps" of flux refining in the range of 1.5. -2.6 L / m2 H, which is comparable to other studies. Any other tests were also carried out to study the performance of the collector thermal solar energy conversion efficiency (percentage) of the heat fairly low average power conversion efficiency solar testing two. approximately 33.6%

Hybrid Solar Portable and refined through a membrane (spmd) system was designed and developed. This research is aimed at. College of Engineering, King Saud University and Riyadh, Saudi Arabia. The hybrid system works in a zero energy concept which does not require external power. And use of solar energy for the operation of memsys v-memd unit successfully. Integrated with solar thermal collectors and photovoltaic systems. In this study, a small test depends on the operating system operated in manual mode. Heat pumps are increasing production. The refined warm brackish water before entering into the v-memd memsys. The results showed that the system runs spmd completely portable. By using only solar energy and without an outside table. Refinery output is estimated at an average rate of 11.53 L / H (tested on 18 Feb 2556), with the highest levels of (L / H (noon) on a total volume of about 70 liters of refined products, with imports of about 4.7. μ S / cm is regarded as the refining yield is low due to the format, the capacity of the system is to meet the rising waters by increasing the number of memsys the "effect" of refined flow in. range 1.5 - 2.5 l / m2 H, which is comparable to other studies, other tests were also conducted performances of the heat. Solar energy conversion efficiency (percentage) of the heat can be quite low. The average energy conversion efficiency of about 33.6 million baht from two tests.
