Domestic Hot Water Preparation and Ventilation with Heat Pumps 6.2.1
Fig. 6.7: Installation requirements for freely drawing in and blowing out
process air.
*)
Minimum clearance between the exhaust air outlet in the air circuit
bend and the wall is 1.2 m
Air ducts/air hoses can be optionally connected on both the air
inlet and the air outlet side. These should not exceed a total
length of 10 m. Flexible, thermally-insulated and sound-
insulated DN 160 air hoses are available as accessories.
NOTE
The condensate produced by the heat pump is lime-free and can be used
for steam irons or air humidifiers.
6.2.1 Air circulation variations
Variable switching of the intake air
A pipe duct system with integrated bypass flap allows the
variable use of the heat extracted from outdoor or indoor air for
domestic hot water preparation (lower operating limit: + 8 °C).
Cooling in recirculating air operation
Indoor air is removed by suction from storage rooms or wine
cellars, and is then cooled and dehumidified in the domestic hot
water heat pump and blown out again. Suitable locations for
installation include hobby rooms, furnace rooms and laundry
rooms. The air ducting in the heated section of the system should
be insulated with water-proof insulation to prevent the formation
of condensate.
Dehumidifying in recirculating air operation
Dehumidified air in laundry rooms can be used to dry laundry and
prevents damage caused by dampness.
Waste heat is useful heat
Our standard heat exchangers (AWP 30HLW and BWP 30HLW
only) for domestic hot water heat pumps enable direct
connection of a second heat generator, i.e. a solar energy
system or a boiler.
