The chosen system is an advanced VRF system with 2 MV6 outdoor units, equipped with inverter compressor with EVI injection technology able to modulate operation by up to 7%, guaranteeing maximum efficiency and savings, and 19 indoor units (wall-mounted, recessed floor, ductable installed in the false ceiling) equipped with flush controls, compact and silent, ensuring a temperature that is always homogeneous.
Air renewal and purification is entrusted to 10 HRV-DX active cross-flow recuperators with direct expansion coil for post heating/cooling and also equipped with the Bioxigen sanitisation module, which reproduces in indoor environments the disinfection phenomenon that occurs naturally outdoors, without chemical additives in a continuous and controlled manner. The Bioxigen® technology in fact releases active ions, continuously removing microbes present in the air and reducing specific volatile organic compounds (VOC) from the indoor environment and surfaces.
The entire system is managed by a CCM-270A centralised touch screen control system with a convenient and simple interface, which allows you to manage the timers daily, weekly or annually and schedule on/off, operating mode, temperature, fan speed, fin oscillation ... room by room. 
Finally, a multi-split system with ecological R32 refrigerant and two BOX-SM 2 cassette-type indoor units was installed to serve the stage control room.
