DESIGNATION KEY

Air Handling Unit

TECHNICAL DATA

The unit is designed for indoor application with the ambient temperature ranging from +1 °C up to +40 °C and relative humidity up to 60 % without condensation. In cold, damp rooms, there is a possibility of freezing or condensation inside and outside the casing.

In order to prevent condensation on the internal walls of the unit, it is necessary that the surface temperature of the casing is 2-3 °C above the dew point temperature of the transported air.
The unit should be operated continuously, and in cases where ventilation is not necessary, reduce the air flow of the fans to a minimum (20%). This will ensure a favorable indoor climate and reduce the amount of condensation inside the unit, which can damage electronic components. Never use the unit for dehumidification, for example, of new buildings.

The unit is rated as a Class I electrical appliance.

Hazardous parts access and water ingress protection rating:
IP22 for the unit connected to the air ducts
IP44 for the unit motors

The unit design is constantly being improved, thus some models may be slightly different from those described in this manual.

DESIGN AND OPERATING PRINCIPLE

Air Handling Unit

Warm stale extract air from the room flows to the unit, where it is filtered by the extract filter, then air flows through the heat exchanger and is exhausted outside by the extract fan.
Cold fresh air from outside flows into the unit, where it is cleaned by the supply filter. Then filtered air flows through the heat exchanger and is moved to the room with the supply fan.

Thermal energy of warm extract air is transferred to clean intake fresh air from outside and warms it up. The air flows are fully separated. Heat recovery minimizes heat losses, which reduces the cost of space heating in the cold season.

Depending on the model the unit is equipped with a supply air preheater or reheater with overheating protection.

The Freshbox E-100 WiFi, Freshbox E2-100 WiFi units are equipped with a preheater.
The preheater is located upstream of the heat exchanger and is designed for its freeze protection.
The Freshbox E1-100 WiFi, Freshbox E2-100 WiFi units are equipped with a reheater.
The reheater is located downstream of the heat exchanger and is designed for extra heating of supply air to more comfortable temperature. When the intake air temperature is below -3 °C, the preheater automatically warms up intake air so the average exhaust air temperature downstream of the heat exchanger is not below +5 °C.
The reheater is switched on and off by means of a button on a sensor control panel, a remote control or via mobile application.
The heat exchanger freeze protection in Freshbox 100 WiFi and Freshbox E1-100 WiFi unit models without a preheater is achieved by automatic supply fan speed reduction according to extract air sensor readings.
The extract fan runs at maximum speed.

Temperature differences between supply and extract air flows in units with polystyrene heat exchangers lead to condensate formation. Condensate is collected in the drain pan and is removed outside by the drain pipes through the exhaust air duct.

Condensate is not formed in units equipped with an enthalpy heat exchanger as moisture is transferred from one air flow to another through a membrane.
The louvre shutters open automatically when the motors are switched on and close when the motors are switched off.

*An additional extract spigot can be fitted to the unit to connect the exhaust air duct from additional premises, e.g. a bathroom.

The spigot is included in the delivery set.
