[TRNSYS-users] Zero Thermal efficiency

[David BRADLEY]

Jibi

   A zero thermal efficiency results at any time that the collector 
cannot produce any useful thermal energy. Efficiency is defined in 
Type563's case as the energy produced divided by the energy input 
(mainly indicent solar). If the collector is not producing any useful 
thermal energy (because the sun is down) then the efficiency is zero.

kind regards,

  David
