Optimization of nominal MTG output versus building size for a cogenerative (heat+electricity) load, with respect to conventional solutions with (a) NGB and (b) EHP
Grahic Jump Location
Optimization of nominal MTG output versus building size for a trigenerative (heat+cooling+electricity) load. MTG operates with AC+ERC+NGB and is compared to ERC+NGB systems.
