Energy
calculations
and
registers
E8,
E9,
E10
and
E11
E8
and
E9
are
used
as
a
basis
for
calculating
the
volume
‐
based
average
temperatures
of
inlet
and
outlet
respectively.
With
every
integration,
the
registers
are
accumulated
by
the
product
of
m
3
x
C,
which
makes
E8
and
E9
a
suitable
basis
for
the
calculation
of
volume
‐
based
average
inlet
and
outlet
temperatures.
E10
and
E11
function
in
the
same
way
as
E8
and
E9,
but
are
used
for
calculating
the
average
t3
in
either
V1
or
V2.
E8,
E9,
E10
and
E11
can
be
used
for
the
average
calculation
during
any
period
of
time
as
long
as
the
volume
register
is
read
at
the
same
time
as
the
energy
registers.

Example
1:
Within
a
year
a
heating
installation
has
used
250.00
m
3
district
heating
water
and
the
average
temperatures
have
been
95
C
in
inlet
and
45
C
in
outlet.
E8
=
23750
and
E9
=
11250.
Example
2:
The
average
temperatures
are
to
be
measured
together
with
the
yearly
reading.
Therefore,
E8
and
E9
are
included
in
the
yearly
reading.
