Flat Plate Solar water heating project

1. System functions and characteristics
1)High efficient, energy-saving and low cost. To make full use of solar energy can save the energy by 80%; Intelligent control can save the labor cost. Once invested, benefit for a long time. The life-span of the whole system is at least 20 years. The investment will be refund in 3-5 years.
2)Safe and reliable. No danger of burning, explosion, poison, electric shock and common water heater has, so it is the most reliable and safe heater system.
3)Environment friendly. Use green energy, solar energy as the main energy resource to avoid the air pollution indoor. Therefore, no waste gas like sulphide, nitride, carbon monoxide and carbon dioxide is produced, following our country environment protection policy, good for country, good for people, to offer a clean and comfortable life space to our customers.

2. Working principal
1)Flat plat solar energy collecting components__composed of series parallel flat plat solar energy solar energy collector, to convert solar radiant energy to heat energy.
2)When the temperature T1 of temperature sensing probe of collector is higher than a set T2 temperature of output water of circulation loop, the intelligent control will start the circulation pump automatically. (compulsory circulation)
3)The circulation pump make working medium cirle in the circulation pump, to pass the heat collected by the collector to the heat storage box, to increase the water temperature contiously in the box.
4)During the working of circulation pump, when the temperature gap is less than a certain point, it will stop working.
5)When the water temperature TR in water box reach the set highest tempeature, the controllor will stop the circulatioin pump. The circulation system has function of automatic emission for over pressure and automatic adusting pressure.
6)The asistant electricity heating system can help to maintain the upper water temperature automatically; Ensure hot water supply in cloudy and raindy weathers.
7)Anti-freezing: When the water temperature of collector is lower than 4º C, the system will activate compulsory circulation system to avoid outdoor collector being frozen in winter.
8)When the water temperature in pipe is lower thant the set point, the conductivity system will start automatic circulation, to ensure enough water pressure to get hot water once the tap is turned on.
