Features
- Total comfort solution for heating, cooling, ventilation and controls
- Redesigned and optimized for total Life Cycle Cost (LCC)
- Engineered to communicate with 80%, 96% and 97% AFUE Daikin communicating gas furnaces
- Intermittent outdoor fan operation during thermal off minimizes snow accumulation on fan blades during off cycles
- New service window provides ease of access to 7 segmented display for commissioning and maintenance
- Best-In-class warranty* with 10-year compressor and parts limited warranty as standard
- 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
- 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.

Technology
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.
Core Technologies
Daikin K-Type Vapor Injection Scroll Compressor
- Compressor technology with patented spiral design and injection valves for precise refrigerant control.
- Strong and efficient motors for optimized compressor performance and part load efficiencies.
- New back pressure control mechanism optimizes the internal compressor pressure with the intermediate pressure adjusting port according to operating conditions. This stabilizes the orbiting scroll, reducing leaks and scroll friction during operation (compared to compressors without back pressure control).
