Problems may arise for users when asked to define "daily inflow of process medium" in the case of processes with variable inflow for different days. Maybe changing to (nominal) flow rate instead of daily inflow would be clearer. Another possibility would be to allow for entering any of the two parameters by ADDING a field for the flow rate.

Copying of EINSTEIN 41 Base Case Example doesn't work well, as flags HeatRecOK and HeatRecExists are in NULL.
-> Base case should be corrected defining these flags
-> Consistency check should be able to deal correctly with NULL's in these flags.

Questionnaire: Energy consumption Electricity Einstein Base case 4.3 If 1000 MWh is the total and e.g. El consumption for Motor is none when a el consumption for Thermal uses exist (steam boiler pump: 60kW) then a list of conflict appears!!! It runs properly when Total =1000 AND (1000 – 156 ) = 844 = ele consumption for MOTORs Moreover what is changed in the checked alternative is the...

When user forgets to link processes to pipes into the questionnaires e Warning should be given because otherwise the DATA set are not consistent (HS 20090520: already done ? To be checked)
Effort: low.

Estimate Qevap = 0 gave problems and has been eliminated (only applied in limit cases); but may make sense for processes where it is KNOWN that there is no latent or chemical energy requirement
Effort: low.

Burners - direct combustion - exhaust gas is no waste heat !!! but treated as such in present-state consistency check and boiler module
Effort: medium.
