Abstract In order to be shown in detail, the design process algorithm (see Fig. 2 in
Chapter
) was divided into two
stages, namely structural design and functional design. In Chapter
“
”
“
”
was presented the
first stage while in this
chapter is presented the second. Then, in Chapter
“
”
it is
shown a concrete example. Here, the functional design was divided into
ve steps
and to each step has been devoted a paragraph. Regarding the contents of steps, this
is as following: In the
first step (described in Sect.
2.1
) the acceptable structural
models resulted from the structural design stage, are completed with all the com-
plementary components (such as recirculation pumps, expansion tanks, heat
exchangers etc.), this way becoming the functional models of the system. After that
all the components, main or complementary, are dimensioned taking into account
both the energetic consumptions of the residence and the internal energetic con-
sumptions of the system. The next two steps (described in Sects.
3
and
4
) consist in
establishing the operation and control strategy of the system, based on which then
the system dynamics is analyzed numerically. Simulation and analysis of the system
operation highlights the system performance in critical moments (such as the
coldest/hottest day of the year, for example), in case of each functional model. The
step described in Sect.
5
consists in designing the monitoring and control sub-
system, which includes choosing the
field equipments, design of the connection
