M. Fehlau et E. Specht, Energy and cost savings in drying processes - Mathematical model determines cost savings and optimal pressure ratio of the vapour compression, BRENN WARME, 51(7-8), 1999, pp. 46
The energy savings from vapour compression entail additional costs for the
vapour compressors and larger heating surfaces of the drier and thus are of
fset to a certain degree. Therefore, a detailes cost-benefit-analysis is re
quired. A mathematical model is presented, which is analytically solvable.
