Non-pressurized Solar Collector for Solar Project

Non-pressurized Solar Collector for Solar Project

Solar Water Heater Project

Large scale solar collectors are formed to generate energy and supply large amount of hot water.

These solar collectors are combined with large tanks and working station for commercial use.

It is professional in central hot water supply of hotel, school, hospital, residence ect.

1. Working Principle: 
1) Firstly, the storage tank shall be filled with cold water, the collector loop shall be pumped with water 

2) The water in collector loop then will be heated with solar radiation to vacuum tubes 

3) When temperature discrepancy sensed between solar collector and storage tank reaches set value in controller, the controller shall start the circulation pump automatically 

4) The circulation pump makes water circulate in the loop 

5) Hot water would be pumped into storage tank and the loop again be pumped with cold water from the bottom of storage tank 

6) In case the temperature in storage tank does not reach set value you want, then the auxiliary electrical heater would start to assist heating 

7) When temperature discrepancy sensed between solar collector and storage tank is below the set value in controller, the circulation pump shall stop automatically 

8) If the water temperature has not reached the expected value set in the controller, then the auxiliary heating device would start to assist solar water heating 

9) Eventually the water will get heated enough as expected ready for use 

2. Features: 

1. Especially for large-scale hot water heating system, supplying hot water for apartments, hotels, restaurants, schools, hospitals, factories, swimming pools, and other places requiring large amount hot water use. 

2. Very economical and of good performance for a 15 years lifespan 

3. Adaptable to different architecture structure installation 

4. Anti-freezing system with good insulation to the pipelines 

5. Easy installation and connection of solar collectors and pipelines 

6. Able to be disigned to work with axuiliary heating devices to assist solar water heating
