Project intern Muhammad Mehdi during system installationĪ series of tests are currently underway to characterize the performance of the system, and finalize its specifications.
Some of the interns doing the work on this project: From right to left, Project Interns: Mahnoor Qayyum, Raphea Siddiqui and Saad Mirza When the water generator is operated it condenses water! Water from thin air! Additional circuit breakers are employed to ensure safe operation: Power inverter and circuit breaker To convert DC power from batteries and solar panel to AC power, a purse sine wave inverter is used. Rechargeable batteries are used to ensure steady power supply, and also enables night-time operation: 12V 100Ah rechargeable batteries
The solar panels used for powering the dehumidifier were mounted on the roof: Roof mounted solar panels to power the dehumidifier The dehumidifier used in our tests is shown below: Dehumidifier rated at 330W and 30 liters/day The power inverter converts the energy stored in the batteries from direct current (DC) to alternating current (AC), and used for running the dehumidifier. The solar panels feed electricity to the charge controller which regulates flow of energy into the rechargeable batteries. Since it is expected to run without need of line electricity, using solar power, the run time will be lower, depending on the sizing of the solar panels. The dehumidifier used in our tests is rated at 330W and capable of condensing 30 liters of water per day if operated for 24 hours at 30C and relative humidity of 80%. The entire cycle is shown below: Design of a dehumidifier based on the refrigeration cycle The warm air flows out, while the refrigerant flows into a condenser where it is compressed and cooled, and is circulated back to the evaporator. The air is cooled well below its dew point which cause the moisture it carries to condenser into water. Heat transfer causes the ambient air to cool, and the refrigerant to vaporize. Electricity is used to blow air past evaporator coils through with cold refrigerant is flowing. The heart of the water generator is the dehumidifier which works on the same refrigeration cycle used in refrigerators, air conditioners and deep freezers. Water production target is 6-8 liters/day in summer and 4-6 liter/day in the winter Our target cost for the system is about $1,000 to $1250.
Two 12V 100Ah Narada rechargeable Gel batteries.One 12V 1KVA Axpert pure sine wave power inverter/charge controller.The system being tested at this time was installed at NED University in Karachi in July 2017. The aim of this project is to develop a water generator that can condense 5-8 liters of water per day from the atmosphere using energy from solar panels. Condensing this moisture using a solar power dehumidifier can provide water for household use. Areas of high relative humidity such as Karachi have 40 grams of air per cubic meter (at 38 C and 85% relative humidity). In many developing countries, lack of water leads to severe hardships and death every year due to uneasy access to groundwater, ponds or lakes especially in deserts and arid lands.
