VRV IV Air-Cooled Heat Recovery
Daikin’s VRV IV systems integrate advanced technology to
provide comfort control with maximum energy efficiency and
reliability. VRV IV provides a heating and cooling solution
for multi-family residential to large commercial applications.
Daikin VRV IV is the first variable refrigerant flow (VRF) system
to be assembled in North America.
Main Features and Benefits:
Total comfort solution for heating, cooling, ventilation and controls
All inverter compressors and inverter fan motors optimize
part load efficiency.
Redesigned and optimized for low total Life Cycle Cost (LCC)
New single/multiple port branch selector boxes provide
compact dimensions and a wide range of product offerings
(single, 4, 6, 8, 10 and 12 port options)
Reduced install cost and increased flexibility as compared to
VRV III with larger capacity single modules up to 14 Tons and
system capacity up to 38 Tons
Efficiency improved over VRV III by an average of 21% with
IEER Values now up to 29.3
Improved seasonal efficiency as compared to VRV III with
automatic and customizable Variable Refrigerant Temperature (VRT)
climate tuning
Best-In-class warranty* with 10 year compressor and parts limited
warranty as standard
Reduced commissioning time vs. VRV III with VRV configurator
software and Graphical User Interface (GUI)
Design flexibility with long piping lengths up to 3,280 ft. total
and up to 100 ft. vertical separation between indoor units
Take advantage of Daikin’s unique zone and centralized controls that
are optimized for the specific needs of North America

AIR COOLED HEAT RECOVERY
VRV IV Operation
Lower capacity is required to cool and heat a building during mid season
Adapting to required heat load by variable re frigerant volume
A VRV system adapts to the required changes in capacit y by var ying the
refrigerant volume. This results in an increase in ef ficiency at part load operation
The ef ficiency of VRV IV is f urther increased by adjusting the refrigerant
temperature dependant on the space load and wea ther conditions
Up to 28% Improved Seasonal
Cooling Efficiency vs. VRV III

PIPING FLEXIBILITY:
The VRV IV provides very flexible piping possibilities.
These generous allowances outlined in the figure facilitate
an extensive variety of system designs.
n
100 ft maximum vertical difference between indoor units
provides greater flexibility for riser type piping layouts.
n
Allows for up to 12 floors to be served from a
single VRV System
n
Ideal for mid to high rise chiller or WSHP
