Flat Plate Solar Water Project

Centralized solar energy heat supply can be widely used for factory, school, army, hotel and public bathroom and others. More and more group begin to use this because of its environment friendly and energy saving. The solar energy heat collector, which Meirun has invested greatly on, has gained increasing good feedback from customers and successfully used in many projects, with its high efficiency, low cost and high reward.

System functions and characteristics
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.
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.
Environment friendly. Use green energy, solar energy as the main energy resource, no waste gas like sulphide, nitride, carbon monoxide and carbon dioxide is produced, to offer a clean and comfortable life space to our customers.

Working principal
Flat plat solar energy collecting components__composed of series parallel flat plat solar radiant energy to heat energy.
When the temperature T1 of temperature sensing probe of collector is higher than a set T2temperature of output water of circulation loop, the intelligent control will start the circulation pump automatically. (compulsory circulation)

The circulation pump make working medium cirle in the circulation pump, to pass the heat collected by the collector to the heat storage tank, to increase the water temperature contiously in the tank.

During the working of circulation pump, when the temperature gap is less than a certain point, it will stop working.

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.

The asistant electricity heating system can help to maintain the upper water temperature automatically; Ensure hot water supply in cloudy and raindy weathers.

Anti-freezing: When the water temperature of collector is lower than 4 centigrade degree, the system will activate compulsory circulation system to avoid outdoor collector being frozen in winter.

When the water temperature in pipe is lower thant the set point, the conductivity system will start automatic circulation, to ensure enough water pressure When the water temperature in pipe is lower than 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.
