MARKET INVESTIGATION
2.1 Introduction
Introduction to the cases
Before looking into the thermodynamical aspects of combining a SOFC
with an absorption cooling unit, a short economical analysis is made in
order to see if there is a market / economical potential for this. Three
different market segments are examined: APU (Auxiliary Power Unit),
CHP (Combined Heat and Power), and DG (Distributed Generation).
Many of the input parameters in the economical model (COPs, prices
etc) have been obtained by contacting several distributers of absorption
and adsorption cooling units asking for preliminary offers. The prices resulting
from this can be seen in appendix A.5 page 219. Other parameters
have been estimated by searching for prices on the internet and reading
reports from agencies such as the ”Energy Information Administration”.
Some data which was not available (e.g. usage time/full load hours for
a given application) has been estimated by the authors. So the results of
the calculations in this section are merely guidelines meant to show if the
synergetic effects of a given application can add up to an amount equal
to or bigger than the extra cost of buying the extra equipment. Sensitivity
analyses have however been made to see how the different input parameters
affect the outcome.
Some general assumptions about the input parameters are described in
