BT AND PT STORAGE TANKS
Storage tanks to be used in heating and cooling systems, to
ensure minimum heat pump operating time in all operating con-
ditions and avoid excessive starts and stops. It can also be
used to isolate the water circuit from the heat pump and to par-
tially meet energy demand during periods in which the unit is
shutdown due to the electricity rate. For indoor installation.
The diagram illustrates the use of the BT/TP storage tank as a
low-loss header to separate the heat pump primary circuit from
the secondary circuit to the terminal units.
This allows different flow-rates and temperatures to be managed
depending on the type of terminal used.
Correctly sized, it guarantees the minimum water volume
required by the heat pump.
