New Range store looks forward to huge savings with Daikin’s latest VRV

Daikin, Air conditioning, VRV
The latest Daikin VRV system in this new Range store is expected to use little more than half the energy of the previous system.

Energy costs for the Daikin VRV IV air-conditioning system at the new Range store in Warrington are expected to be 47% less than for a VRV III system with standard cassettes. The installation for the shop floor comprises seven twin-module VRV IV heat-pump condensing units and 71 self-cleaning Roundflow cassettes. They are under the control of a Daikin RTD intelligent retail control system.

Whilst air conditioning is often set to a nominal 21°C, the VRV IV heat pump is set to operate within a set temperature band to save energy, Heating is also not interrupted during defrost to ensure continuous comfort.

The VRV IV heat pump achieves a 28% increase in efficiency compared with the VRV III heat pump, and the refrigerant temperature can be adjusted to the actual temperature and capacity required, optimising efficiency at all times.
