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.

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.
standard angle to ensure optimal heat pipe
operation.
-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
-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.
We successfully finished this project!
