Enerk Design Software for HVAC Enerk A.H.C. van Paassen and T.P. van der Stelt Mei 2003

Enerk The program must be recognizable for the designer, i.e. he must have the possibility to indicate his wishes in a Mollier-diagram The program must be useful in early development stages The program must be clear and educationally justified Objective of the program
