SETTING THE STANDARD AGAIN
VRV IV Air-Cooled Heat Pump
Daikin’s VRV IV systems integrate advanced technology to
provide comfort control with maximum energy efficiency and
relabilty. Currently available in heat pump configurations,
VRV IV provides a solution for multi-family residential to large
commercial applications desiring heating or cooling. The VRV
IV is the first variable refrigerant flow (VRF) system to be be
assembled in North America.
Features:
Total comfort solution for heating, cooling, ventilation and controls
Redesigned and optimized for total Life Cycle Cost (LCC)
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 34 Tons
Efficiency improved over VRV III by an average of 11% with IEER
Values now up to 28
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 100 ft. vertical separation between indoor units
Take advantage of Daikin’s unique zone and centralized controls

VRV IV Operation
Lower capac ity is required to cool and heat a building during mid season
Adapting to re quired heat load by variable refrigerant volume
A VRV system adapts to the requir ed changes in capacit y by var ying the
refrigerant volume. This results in an increase in efficiency at part load op eration
The ef ficiency of VRV IV is fur ther increased by adjusting the re frigerant
temperature dependant on the space load and weather conditions
