The unit is housed in a sound-insulated casing (item 1).
The connecting pipes of the unit form a single structure with the unit casing.
The function of the connecting pipes (item 7) is indicated on the stickers on the unit casing.
The supply fan (item 10), exhaust fan (item 11) and heat exchanger (item 12) are also located inside the unit casing.
The function of the connecting pipes of the unit depends on the unit modification (left- or right-handed modification).
The product modification is determined by the location of the temperature sensor (item 12), the humidity sensor (item 13) and the
connection of the motors in the control unit (item 8).
The location of the sensors and the function of the connecting pipes after the system has been assembled at the factory is shown in the
upper image (right-handed modification).
Bottom side of the casing is covered with a removable cover (item 2), which is fastened with 4 plastic screws (item 3).
Under the covers (item 5) there are the exhaust and supply air filters.
A control unit (item 3) is installed in the casing.
The power and control cables are pulled through cable glands (item 9).
Condensate is removed from the unit casing through a drainage pipe (item 6).
UNIT OPERATION MODE
Heat exchange: warm extract air from the room flows into the unit and is cleaned in the extract filter. Then the air is moved through the
heat exchanger and is exhausted outside with the extract fan.
Cold fresh air from outside flows through the air duct into the unit, where it is cleaned by the supply filter.
Then the air flows through the heat exchanger and is moved to the room by the supply fan.
Supply air is heated in the heat exchanger due to transfer of the heat energy of warm and humid extract air to the cold fresh air.
The air streams remain separated in the heat exchanger.
Heat recovery minimizes heat losses, which reduces costs for space heating in the cold season.
Reneo-Fit D 100-E S14 units use an enthalpy heat exchanger to recover not only heat but also moisture.
In summer, the heat exchanger cools and dehumidifies the supply air, and in winter, it heats and humidifies it.
Water vapour condenses from the moist exhaust air and is absorbed by the heat exchanger plates.
The resulting moisture and heat are transferred to the supply air.
Defrosting: in order to protect against icing during cold seasons, the unit is equipped with an automatic defrosting mode controlled by
readings of the defrosting temperature sensor located in the exhaust duct behind the heat exchanger.
The unit enters defrosting mode when the exhaust air temperature drops below +3 °C.
After increase of these temperatures the unit reverts to the previous operation mode.
In the defrosting mode, only the exhaust fan runs, the supply fan is switched off.
