After selecting the most appropriate model in the Energy Plus range, it is possible to iden-
tify the parameters for correct calibration of the machine and, therefore, the characteristic
performance parameters.

The aim here is to install a primary air ventilation system with very high thermal recovery per-
formance in an average-sized store.
The ventilation unit is to be inserted in a 4-pipe central air conditioning system provided by the
owner and used for water terminals.
The store is located in a climate area characterised by cold winter temperatures (climate area
E, design temperature -8°C).
Primary air is to be used as the energy carrier for summer air conditioning.
The design data for selection of the machine are summarised below:
On the basis of the calculated flow rate, the Energy Plus model is selected as the most suita
-
ble, together with all the necessary accessories.
Supply configuration selected:
Below is an example of selection of the machine that can help to explain calibration:
