VRV IV X Heat Pump

Adapting VRV to North America.

Engineered and assembled in North America; Daikin's VRV IV X adapts VRV to North American HVAC market needs by expanding the applications in which VRV can be leveraged to solve traditional challenges. Packed with advanced technology, VRV IV X is the industry's first 3-phase VRF system with dual-fuel capability, after Daikin's launch of 1-phase VRV LIFE in 2018. The new series is equipped with features to optimize initial capital required on phased installations and provides ease of service and maintenance.

What’s new about VRV IV X?

Dual Fuel Capability with Gas Furnace Connectivity

VRV IV X is industry's first 3-phase VRF system to integrate with communicating gas furnaces. Connects with 80%, 96%, 97% AFUE Daikin communicating gas furnaces. Engineered for dual fuel capability, offering a choice of heat pump or gas furnace heating.

Easy Maintenance with the new Service Window

New service window provides ease of access to the multi-functional display without removing the main electrical panel. The built-in multi-functional display is utilized for commissioning and maintenance and quickly converts to digital gauges to provide refrigerant pressure and temperatures.

Engineered for Flexibility and Expansion with the new Phased Installation

VRV IV X delivers enhanced design flexibility thanks to its ability to expand with the building's phased construction. Provides option of increasing the overall system size from single to dual module or from dual to triple module without changing the main pip sizes. Help reduce initial capital and design complexity compared to systems that do not offer phased installation. Designed to optimize initial capital investment for multi-phase projects .

VRT (Variable Refrigerant Temperature) —

STATE-OF-THE-ART ENERGY-SAVING TECHNOLOGY FOR VRV

Variable Refrigerant Temperature

img vrv iv X

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.

img vrv iv X

 

  • 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.
