Daikin FXFQ32LUV1 [10/84] Cooling load capacity
VRT-VARIABLE REFRIGERANT
TEMPERATURE
STATE-OF-THE-ART ENERGY SAVING TECHNOLOGY FOR VRV SYSTEM
How is energy reduced?
During cooling, the refrigerant evaporating
temperature (Te) is raised to minimise the
difference with the condensing temperature.
During heating, the condensing temperature (Tc) is
lowered to minimise the difference to the
evaporating temperature. Compressors work less,
and this reduces power comsumption.

Customise your VRV system for optimal annual efficiency
The new VRV IV system now features VRT technology.
VRT automatically adjusts refrigerant temperature to individual
building and climate requirement, thus further improving
annual energy efficiency and maintaining comfort.
With this excellent technology, running costs are reduced.
Required capacity changes
as airconditioning load
changes according to
outdoor temperature.
Energy efficiency is
improved without
sacrificing comfort.
Automatic control adjusts
evaporating temperature
to heat load change.
In case of fixed evaporating
temperature, excessive cooling,
thermo on-off loss, and other
inefficiencies occur.
