Daikin has upgraded the design of its RZQ Super Inverter (1 phase) and RZQS Comfort Inverter, developed for use in offices, shops and restaurants, thereby increasing efficiencies throughout both ranges. In the case of the RZQS100 for example, cooling and heating efficiencies are improved by up to 23% and 11% respectively over those of the earlier model. Both RZQ and RZQS units continue to support the connection of a wide range of indoor units and retain their wide temperature operating range.
The new RZQ-D Super Inverter currently returns the highest COPs and EERs on the market with energy label ‘A' ratings in most configurations and like previous RZQ units, it also has an extended operating range from -15°C to 50ºC (cooling) and 15.5°C down to -20ºC (heating).
The unit is flexible with respect to piping diameter and although it utilises R-410A refrigerant, it also allows the re-use of existing R-22 or R-407c field piping with piping lengths up to 75m possible. This ensures easier installation and lower installation costs when upgrading existing buildings. The RZQ is also suitable for technical and computer room cooling.
