Phased Installation
VRV IV X delivers enhanced design flexibility thanks to its ability to expand with the building's phased construction.
- Expand the system from a single to a dual module or from dual to triple module without changes to main pipe sizes that are already installed.
- Help reduce initial capital and design complexity compared to systems that do not offer phased installation.
- Optimize piping design, branch selector boxes, and indoor units per phase of installation.
Gas Furnace Connectivity
Expanding VRV into applications that were limited to gas-based heating, VRV IV X is the first 3-phase dual-fuel VRF system in North America that integrates with communicating gas furnaces.
VRV IV X offers outstanding design flexibility when connected to Daikin communicating 80%, 96%, and 97% AFUE gas furnaces and CXTQ coils. The new VRV IV X enables the use of VRV technology to provide utility cost based heating solutions. With the flexibility to switch between electric heat pump heating and gas heating, operational costs can be optimized to building owner's choice for a heating source.
- Space-saving with ability to connect multiple gas furnaces to one outdoor unit with 14 selectable settings.
- Customizable changeover temperatures to switch from heat pump to gas heat.
- Ability to provide system-wide heating independent of outdoor ambient temperature.
Daikin’s new VRV IV Heat Pump offers a simplified range of condenser unit combinations with the expanded capacity to fit more projects when compared to VRV III. Ranging from 6 to 34 tons in a single system, all versions of the VRV IV feature inverter controlled compressors and the new Variable Refrigerant Temperature control cycle for improved seasonal efficiency when compared to VRV III. Available in 208-230V & 460V and 575V versions.

VRT (Variable Refrigerant Temperature) —
STATE-OF-THE-ART ENERGY-SAVING TECHNOLOGY FOR VRV
Variable Refrigerant Temperature
ADAPTIVE AND LEARNING VRT
The new VRV IV X system features a newly enhanced learning VRT technology. The new learning VRT technology, in addition to helping with annual energy efficiency and maintaining comfort, provides features that enable time-based learning to adjust cooling and heating capacities to provide a stable capacity to the indoor units. The feature must be activated through field setting changes.
HOW IS ENERGY REDUCED?
A standard VRF system and previous Daikin VRV systems utilize a capacity based control logic where the system will adjust to meet the capacity requirements of the space. With VRT, Daikin has optimized focus not only on capacity but also on efficiency and comfort.
According to changes in the room's heat load and the ambient air temperature, the evaporating temperature (in cooling) and condensing temperature (in heating) are automatically adjusted to minimize the difference with the condensing temperature and the evaporation temperature, respectively.
This makes the compressors work less and also enables the system to always maintain the ideal compressor speed so that the Daikin VRV system can deliver the optimum efficiency.
- Can boost capacity above 100% if needed. The refrigerant temperature can go lower in cooling than the set minimum.
- Gives priority to very fast reaction speed. The refrigerant temperature goes down fast to keep the room setpoint stable.
- Gives priority to fast reaction speed. The refrigerant temperature goes down fast to keep the room setpoint stable.
- Gives priority to efficiency. The refrigerant temperature goes down gradually giving priority to the efficiency of the system instead of the reaction speed.
