3. A decentre drinking water supply means a higher effectively. The pressure of the solar submersible pumps (up to 36 W) is fully enough to run the filter.
4. The filter is outstanding better than ordinary filter systems and this is without chemical water treatment; this means there is no adverse reaction with chemicals.
5. This high-tech is very simple method which can increase the efficiency and minimize the costs in order to gain drinking water. Up to 200 litters clean drinking water daily means a higher living standard for about 100 people.
SPECIFICATIONS
The solar submersible pumps deliver water with a pressure between 0.5 till 2 bars into the filter, which meets hundreds of hollow capillary filter films. The filter aperture is less than 0.01µm (1.0/1.000,000 mm). The pure water runs through the filter film in vertical direction while some bacterium bigger than 0.01 µm and other various impurities fail to pass the filter film and is drained off with the running water through the faucet for tap water in to a water tank. The lifetime of a filter is about 3 years. Regular cleaning is very simple. Just change the input and the output and the water flow from the opposite direction.

INTRODUCTION:

NON-PRESSURIZED COMPACT SOLAR WATER GEEZER Solar water heating or solar hot water is water heated by the use of solar energy. Solar heating systems are generally composed of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage. The system may use electricity for pumping the fluid, and have a reservoir or tank for heat storage and subsequent use. The systems may be used to heat water for a wide variety of uses, including home, business and industrial uses. Heating swimming pools, underfloor heating or energy input for space heating or cooling are more specific examples. In many climates, a solar hot water system can provide up to 85% of domestic hot water energy. This can include domestic non-electric concentrating solar thermal systems. In many northern European countries, combined hot water and space heating systems (solar combisystems) are used to provide 15 to 25% of home heating energy. Non-pressurized compact solar water heater is a kind of solar water heating system that solar collector and storage water tank are connected together, water tank on the top and collector panel on the bottom. It relies on the natural circulation of waters between the collector and the water tank. As water in the vacuum tubes is heated, it rises naturally into the tank, while cool water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system. It moves household water or a heat-transfer fluid through the system without pumps. It is a simple and safe solution to get heat power from the sun. Feature: 1. Fluorocarbon (FVDF100) crust 2.

Corrosion resistant silver brazed copper header WORKING PRINCIPLE OF SOLAR WATER HEATING SYSTEM Product Description Split Solar Water Heating System use electric pumps, valves, and controllers to circulate water or other heat transfer fluids through the collectors. Their storage tanks do not need to be installed above or close to the collectors, and with electric back up inside for no enough sunshine. Even if in cloudy or rainy days, you can enjoy hot water. Open-Loop Split Solar Water Heating System This system use pumps to circulate household water through the collectors. This design is efficient and lowers operating costs. Closed-Loop Split Solar Water Heating System This system pumps heat-transfer fluids (usually a glycol-water anti-freeze mixture) through the collector. Heat exchanges transfer the heat from the fluid to the household water that is stored in tanks. Closed- loop glycol systems are popular in areas subject to extended subzero temperatures because they offer good freeze protection. Working principle of Split Solar Water Heating System: This split solar water heating system has solar collectors on roof and water tanks inside the house, and transfers heat energy collected by the collectors into the tank by natural or forced circulation of the working fluid between collector and the tank. Components: The system comprises of solar collectors, a water tank, a heat exchanger, a controller and pumps. Functions of Split Solar Water Heating System: 1. Constant temperature circulation: adopt the auto circulation system to realize constant temperature of the water inside the solar system; Ex-factory default is to ensure the constant temperature of water inside the system and pipelines. 2. Overheat protection: It includes protection of solar collector and electric booster. The former will be operated by the controller automatically to ensure the safety of the solar collector and the solar heat storage system; the later will be controlled by the temperature sensor automatically, to make sure the electric booster work in a safe condition. Take manual operation to resume to the working station. 3. Pressure limitation: It functions by automatically sensing the pressure and temperature of the parts, so as to ensure the normal operation of the system. 4. Anti-freezing: It is realized through the circulation of the working fluid to make sure the safety of the operation at the limited temperature. FEATURES OF SPLIT SOLAR WATER HEATING SYSTEM: 1. The solar collector is separated with the water tank; the water tank can be located anywhere; 2. Solar collector can be mounted on buildings in different styles; 3. U pipe solar collector with anti-freezing fluid inside the tubes will achieve high anti-freezing effect; 4. Intelligent control system is reliable and convenient; 5. Pressurized operation will guarantee sufficient water flow; 6. Solar water heating system can be connected with auxiliary heating source at the preset joint. PRESSURIZED SOLAR COLLECTOR – EVACUATED SOLAR TUBE COLLECTOR HOW DOES IT WORK? The operation of the solar collector is very simple. Solar absorption: solar radiation is absorbed by the solar tubes and converted into heat. Solar heat transfer: heat pipes conduct the heat from within the solar tube up to the header pipe solar energy storage. Water is circulated through the header, via intermittent pump cycling. Each time the water circulates through the header, the temperatures is raised by 5-10oC. Throughout the day, the water in the tank is gradually heated.
