Integration of the heat pump in the heating system 8.15
8.15 Hydraulic integration
The heating system control is identical for air-to-water, brine-to-
water and water-to-water heat pumps; however, the hydraulics
for the integration of the heat source are different.
The integration diagrams shown on the following pages show
standard solutions for the most common applications. The heat
pump manager controls the individual components. The dia-
grams show the contacts and the hydraulic components of the
domestic hot water distribution system (in dashed lines). The
max. permissible heating water flow rate must be adhered to
(see Chapt. 8.4 on page 97).
Additional integration diagrams can be downloaded from the in-
ternet at www.dimplex.de.
