Solar Thermal System Installation process

The most recent construction project is the installation of solar water-heating system in large public building; the town hall of Yecheon-gun, Korea.

Date of construction completion : 2011.05.28


 
      Evacuated tube solar collector
      Model  : SWH 1500-16
      42 pieces of solar collectors
















Pre- installation site visit & installation planning

- Visit the site and make a construction plan considering  the suitability of  the place.
- The installation location is on the rooftop of the Town Hall.
-Check the optimum crane location for lifting of materials using crane.






Material transportation &  basic construction work  
- Materials are moved onto the rooftop of the 
   building using crane.
-  Set foundation anchor bolts in concrete for 
   installing structure.













Structure installation for setting solar collectors

-Frame feet should be bolted to the installation surface and be installed at the 
  standard angle to ensure  optimal heat pipe 
  operation.











Solar collectors installation
-The solar collectors are be placed upon the structure.
-Be careful when handling the evacuated tube, as they will  break if knocked dropped or heavily.














Plumbing connection &
Foundation concrete
After solar collectors installation, the manifold are connected to the system plumbing




Installation of vertical plumbing

If plumbing pipes are not accommodated in the interior wall, vertical plumbing should be installed in outside wall using safety equipment.
















Covering
- Remove  the vinyl cover from the solar  collectors
- High temperature resistant covers should be placed over the collectors to prevent  heat rising prior to the system  operation.

 









The solar heat storage (storage tank) installation
When the completed storage tank cannot be delivered to the site as the door to mechanical room is narrow, the storage tank should be installed in the mechanical room right there.




Installation of the plumbing mechanical package
-All mechanicals and components such as the solar heat storage, expansion vessel, heat exchanger and circuit pump are placed in 
suitable location and connected with plumbing pipes.



                 
Pressure test & Cleaning                                                                                  
-After connecting all pipeline, pressure test and pipe cleaning are carried out, then check for a water leak.
                                                                            

                                                            








 


Pipeline covering for keeping warmth
-Copper pipes and exposed components  should be covered and wrapped  to insulate.










Mounting the control unit &
The system test
-Sensors are the signal cables are connected to the control unit.
- Via the controller, you can check the temperatures and  the production of solar thermal system at any time.
