Daikin sets the standard yet again with the 4th generation of VRV. VRV IV achieves a new benchmark for efficiency, as it features major enhancements to the already industry-leading VRV solution. VRV IV offers three revolutionary innovations: -

  • * Variable Refrigerant Temperature
  • * Continuous Heating during Defrost
  • * VRV Configurator


Variable Refrigerant Temperature Technology

 Allows the installer to customise the system using a choice of presets, to optimise the energy and comfort balance for the individual project. In automatic mode, the system is configured for the highest efficiency levels throughout the year, while allowing rapid response on the hottest days, ensuring comfort at all times.

This technology delivers a 28% increase in seasonal efficiency, because the system continually adjusts the refrigerant temperature according to the total required capacity and the external weather conditions.

Continuous Heating during Defrost

Another revolutionary innovation that sets a new standard in heating comfort, making VRV IV the best heat pump alternative to traditional heating systems.

Continuous heating finally overcomes any perceived disadvantages of specifying a heat pump, because the heat pump continues to provide heating even when in defrost mode.

Why is this important? All heat pumps accumulate ice during heating operation, which must be melted periodically. Previously, defrost operations reverse the refrigeration cycle, causing a temporary temperature drop within the room. VRV IV features a unique heat accumulating element, which provides dedicated energy for the defrost function, so the indoor units continue to provide heating and a comfortable indoor climate is maintained at all times. 

New VRV Configurator

This completes the trio of innovations and offers an advanced software solution which simplifies commissioning and customisation. This means less time is required on the roof configuring the outdoor unit. Ongoing maintenance is easier too, thanks to a graphical interface that allows engineers to evaluate operational data and errors. The VRV configurator also allows multiple systems within multiple sites to be managed all in exactly the same way, thus offering simplified commissioning for key accounts.


VRV IV Integrates with Intelligent Solutions

To complement the VRV IV system, Daikin’s new Intelligent Touch Manager offers an intuitive user interface with a visible floorplan, which can manage up to 2560 groups of indoor units and provides energy management tools to maximise efficiency.


The VRV IV system can be used together with a wide range of ventilation units, hot water hydroboxes, Biddle air curtains and Daikin’s latest round flow cassettes, which feature a daily auto-cleaning filter that reduces energy consumption over the year by up to 49% . The round flow cassette is also available with a presence sensor that adjusts the set point or switches off the unit when nobody is in the room, saving a further 27% in energy consumption.
