The needs

The air conditioning system of the store was built in the 1980s. It consisted of two air conditioning systems with vents and a fresh air intake system. In the ventilation installation there was no concern for energy savings.

The operation of the facility could no longer be supported, as the type of machinery and spare parts have been withdrawn and are no longer produced.

There was a need to redesign with modern equipment and with care to save energy.

The interventions

With the new design, the two air conditioning systems and the ventilation system were integrated into a single air conditioning system of VRF technology.

MITSUBISHI equipment was selected.
