A Daikin VRV IV system is delivering high levels of comfort in DM’s flagship store in Vösendorf, Austria, which features beauty treatment rooms and a hair salon.

Heating and cooling demands in the DM store can vary dramatically throughout the year, with the added complexity that the climates of the five treatment rooms and hair salon have to be controlled independently.

A VRV IV monovalent system was the perfect solution, as it could create the different climatic zones.

VRV IV features Variable Refrigerant Temperature technology, which continually adjusts refrigerant temperature to match heating or cooling demand and the outside temperature. This means less power is needed, efficiency is higher and comfort is improved.

In the DM store, one VRV IV Multi-system outdoor unit is linked with 10 Roundflow cassettes serving the shop floor, while another VRV IV unit is linked with three concealed duct units in the salon and one concealed duct unit in each of the five treatment rooms.

This allows the temperature and air flow in the salon and the treatment rooms to be controlled independently of one another and the main sales area.
