Types of elements and corresponding static pressure losses
As mentioned above, the total loss of static pressure, which can be calculated by
adding up the losses of individual elements built into the pipeline system, may not
exceed 90 Pa. If they do, the values of COP start dropping more dramatically.
Example of calculation:
Elbow 90°
Flexible tube
Air intake grid
Roof vent for waste air
Total:
To prevent pressure depression in the building, fresh
air must be regularly supplied to the premises. The
desired rate of air exchange for a residential building is
0.5. This means that the entire quantity of air in the
building is exchanged every two hours.
Connecting the heating pump to the same pipeline as
the kitchen extractor fan or taking air out of several
smaller apartments or suites is not allowed.
During the operation of the heating pump, condensate
is formed in within the aggregate. It must be led into
the sewage by means of a flexible condensate
drainpipe ø16 mm on the backside of the heat pump. The quantity of condensate
depends on air temperature and humidity.
To reduce the transfer of noise and vibrations of the built-in fan, please take the
following measures to prevent the transfer of noise and vibrations through the walls
into premises where this would be disturbing (bedrooms, rooms intended for resting):
- install flexible joints for hydraulic connections
- install a flexible tube for the pipeline of inlet/outlet air
- plan vibration insulation for wall openings
- plan noise dampers for inlet/outlet air
- pipelines for inlet/outlet air should be attached using noise dampers
- plan insulation to prevent floor vibrations
- use positioning feet.
