Water-cooled VRV delivers energy-efficient HVAC to refitted fashion retail store


Daikin Roundflow cassettes’ automatic daily cleaning function, which maintains air flow, improves efficiency and lowers running costs, was a key factor in their selection as part of the water-cooled VRV system in C&A’s store in the Nový Smíchov shopping mall.

Nový Smíchov in Prague is one of the largest shopping malls in the Czech Republic, with a retail area of about 60,000m2.

German fashion retailer C&A operates a 1,600m2 store in the mall, which underwent a major refurbishment in 2013, which included replacing its HVAC system.

C&A needed a climate control solution that ensured comfort all year round, efficiently and cost-effectively.

It chose a Daikin system comprising four water-cooled VRV outdoor units (VRV-W) linked the shopping mall’s water loop. These serve 20 indoor units, including 18 self-cleaning Roundflow ceiling cassettes throughout the shop. Three further VRV-W units are connected to an air handling unit delivering fresh air to the store. 

The Roundflow cassettes’ self-cleaning function was a key factor in the Daikin system being chosen. Daily auto-cleaning prevents dust accumulating on the filters, increasing efficiency, reducing running costs and improving comfort through consistent air flow distribution. Dust can be removed every six months using a vacuum cleaner.

The system is controlled via a Daikin intelligent Touch Manager, linked (via a RTD20 adaptor) with the Building Management System.
