Daikin launches new VRV R Series Heat Recovery System

Daikin Australia has launched the newest addition to its VRV range – the VRV R Series (REYQ-BYM).

Daikin says the sixth-generation model enables simultaneous cooling and heating operation in a single VRV system, and boasts considerable improvement over previous generations.

“Daikin VRV systems have continually set the standard for energy efficiency, reliability and comfort for 40 years,” says Daikin National Commercial Manager Simon Langstaff, Affil.AIRAH.

“The new VRV R is no exception, offering a range of unique new functions for increased design flexibility and optimum performance.”

According to Daikin, the new system was designed to be used in both single and multi‑module combinations that help to reduce the overall space required for mechanical equipment and the number of electrical and piping connections.

Single modules starting at 8HP capacity are now available in three sizes thanks to the addition of a large-capacity XL chassis with 22 and 24HP (67.0kW) capacity that sits at 1,750mm wide x 765mm deep x 1,660mm tall. This represents a 4 per cent reduction in total footprint and 11 per cent reduction in weight compared to the fifth‑generation VRV Series.

The new VRV R is equipped with hardware and software innovations designed to improve the energy efficiency of the system.

“The patented High Efficiency P-Type Compressor is optimised for part-load performance and delivers a part load EER (at 50 per cent load) of up to 7.82,” says Daikin. “This delivers an efficiency improvement of up to 25 per cent compared to Daikin’s fifth-generation model.”

Refrigerant piping length and maximum height difference have also been increased for the VRV R, to better cater for large-scale buildings. According to Daikin, refrigerant piping lengths of up to 165m are possible and the maximum height difference between the indoor unit and the outdoor unit has been extended to 110m, an improvement of 20m from the fifth-generation model.

Other features include improved insulation on the new 4- to 12-port models, that Daikin says negates the need for a condensate drain connection; a new outdoor multi defrost function that allows each heat exchanger to enter defrost mode at different times; an improved sealed electrical box design with an ingress protection rating of IP55 and a new service window for access to the multi-functional digital display; and separate wiring and piping for quick access and installation.
