a) Operation using ambient air
In this type of operation, the device heats
domestic water using only the amount of
energy generated by the air from the room
where the device is installed. The heat pump
must be installed in a ventilated, frost-free
room, possibly in the vicinity of other heating
sources. For optimal performance of the heat
pump, we recommend a sufficiently large and
well ventilated room with the temperature
ranging between 15 °C and 25 °C. It is vital to
ensure sufficient intake of air in the room.
Elbows must be installed on the heat pump
and turned so that they prevent the mixing of
air. Heat losses are greater in premises with
colder air.
If the heat pump is installed in a frost-free
room and the temperature is under 7 °C, the
heat pump operates in the normal mode of
operation.
b) Operation using air from other premises
In this type of operation, the heat pump uses air from other premises via a pipeline
system. It is advisable to insulate the pipeline system to prevent the formation of
condensate. In case of using air from outside, the external part must be covered so
as to prevent the intrusion of dust or snow into the appliance.
Besides the drag in the pipes and elbows, the user should be aware that increased
drag also increases noise levels.
In case of using air from outside, the user should adhere to the minimum diameter of
the pipes ø125 mm or □150x70.
To make sure the operation of the pump is effective at all times, you can install
dampers to take air from the premises and then return it either to the premises or
outside. If the temperature of air is under -7 °C, heaters for the heating of domestic
water are switched on. The heat pump operates in reserve mode.
