Arena Centar, in the south west of Zagreb, is known as Croatia’s premier shopping centre.
This architecturally-impressive building features wide shopping malls and glass ceilings and is home to 10 large, and more than 200 small to mid-sized, stores plus a large supermarket and entertainment venues.
As with any large shopping centre, it is important to ensure shoppers’ comfort as they move around the mall areas and in individual shops, whatever the weather.
Climate control is provided by a water loop-based HVAC system using McQuay chillers. Each shop has its own water source heat pump to deliver heating and cooling, connected to a central building management system.
Ventilation and air conditioning of the mall areas is provided by air handling units linked to a Daikin chiller. Offices in the supermarket and bowling alley are served by VRV III heat pump systems.

Daikin and McQuay chillers are at the heart of the water-cooled system.

The chiller units are mounted on the roof of the shopping centre and provide climate control to more than 200 shops and entertainment venues.
