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.
The VRV-W units are linked with the shopping centre’s water-cooled system.
Self-cleaning Roundflow cassettes are low maintenance and highly efficient, saving energy and cutting running costs.
An intelligent Touch Manager controls the system inside the unit and links easily to the shopping centre’s Building Management System.
