Ventilation preheating and -cooling
In summer, the indoor temperature may be pre-set. Cooling is deactivated at the pre-set temperature.
The Airobot ventilation unit monitors air supply temperature and ensures that it does not drop too low. The minimum air supply temperature is calculated in real-time using the dew point formula, in order to avoid condensation in the ducts.
For controlling the device, the Airobot ventilation unit must have the external control capability (EXT-CTRL) option configured.
The calorifier is installed between the outdoor air duct and the unit. The circulation pump is not included; consult a heating specialist to determine a suitable pump.
The ventilation system has low air volumes per room and this system does not meet the standards set for cooling systems. This solution provides some cooling but is not comparable to an AC or similar cooling system.
The ground may warm up in summer, resulting in higher brine temperatures and eventually no capacity for storing extracted heat.
The system enables the storing of summer heat in the ground (in preparation for the next heating season), which improves the winter efficiency of the ground source heat pump.
The calorifier is available in three sizes: 160 mm, 200 mm and 250mm diameter fittings.
A filter cartridge must be installed upstream of the calorifier to minimize debris accumulation. Depending on the size: FD 160m, FC 200 mm or FD 250 mm.
