Dimensionnement d'installations de chauffage par pompe à chaleur
WPCalc represents a powerful tool for designing heat pump heating systems with ambient air, ground water and vertical ground heat exchangers. However, ground heat exchangers have been treated by a rather simplified simulation approach so far. The incorporation of the above mentioned module EWS is scheduled for the end of 2000, and will significantly enhance the design capabilities of WPCalc for ground coupled heat exchangers. Infomation on WPcalc is available from Huber Energietechnik, Martin Stadler [ stadler@igjzh.ch ].
Dimensionnement des sondes géothermiques et réseaux de sondes géothermiques
Earth Energy Design (EED), was developed by G. Hellström and B. Sanner. The initial phase in the design and dimensioning of a ground heat system generally needs an easy-to-use method by which the basic thermal behavior of the system may be assessed. Information on EED is available from >> [ buildingphysics.com - Web link ].
EWS was developed by A. Huber, O. Schuler and D.
Pahud. During the last years, several programmes have been developed to
simulate heat pump systems, such as TRNSYS (Klein et al., 1996), YUM (Afjei,
1995) or WPcalc (Nani et al., 1994). EWS calculates the source
temperature for ground coupled heat pumps with vertical heat exchangers being
adjustable to the three aforementioned simulation programmes. The now updated
version of EWS enables also the calculation of the entire lifetime of fields of
ground coupled vertical heat exchangers. Additionally, a data exchange is also
possible with the programme SwEWS (see below). Infomation on EWS is
available from Huber Energietechnik [ huber@igjzh.com ]

SwEWS was developed by W. Leu, B. Keller, Th. Mégel,
U. Schärli and L. Rybach. In combination with a simple evaluation software
tool, SwEWS contains a valuable data base of geothermal properties
of typical rocks of the Swiss Molasse Basin. SwEWS allows the analysis of a
specific depth profile defined by the user. Thus, the precision of heat
extraction simulations with software packages like COSOND, TRNSYS, EWS or
WPcalc can be significantly enhanced when integrating SwEWS as a modul.
