Lessons learned |
|
|
Initiative |
The user, a Kibbutz, initiated the project but could not initially find high-end solar thermal collectors to supply the temperatures needed.
|
|
Integration methodology |
Solar loop circulates against heat exchanger heating a 5 m3 tank. The water to the process goes to a laundry (no return). Any missing energy is added by on-line gas heaters.
|
|
Crucial Interfaces |
Overheating prevention is at the collector level
|
|
Construction / Commissioning |
|
|
Operation / Performance |
The collectors provide energy as expected. March 2014 frequently saw 100 C circulated. This is not supported by other heaters in this loop because added energy is on-line.
