1 Features
OutdoorUnit VRVSystems SB.RKXYQ-T VRVIVheat The invisible VRV
• Unique VRV heat pump for indoor installation
• Unrivalled flexibility because the unit is split up into two elements: the
heat exchanger and the compressor
• Highly suited to densely populated areas thanks to the low operation
soundandseamlessintegrationintosurroundingarchitectureasonly
the grille is visible
• Incorporates VRV IV standards & technologies: Variable Refrigerant
Temperature, VRV configurator and full inverter compressors
• Covers all thermal needs of a building via a single point of contact:
accurate temperature control, ventilation, air handling units and
Biddle air cutains
• Customize your VRV for best seasonal efficiency & comfort with the
weather dependant Variable Refrigerant Temperature function.
Increased seasonal efficiency with up to 28%. No more cold draft by
supply of high outblow temperatures
• VRV configurator software for the fastest and most accurate
commissioning, configuration and customisation
• Lightweight units (max. 105kg) can be installed by two people
• Unique V-shape heat exchanger results in compact dimensions (h/e
unit only 400mm high) allowing false ceiling installation, while
ensuring top efficiency
• Super efficient centrifugal fans (over 50% efficiency increase
compared to sirocco fan)
• Small footprint compressor unit (760 x 554 mm) maximizing useable
floor space
• Connectable to all VRV control systems
• Keep your system in top condition via our i-Net service: 24/7
monitoring for maximum efficiency, extended lifetime, immediate
servicesupportthankstofailure prediction and a clear understanding
of operability and usage

Notes
(1) Nominal cooling capacities are based on: indoor temperature: 27°CDB, 19°CWB, outdoor temperature: 35°CDB, equivalent refrigerant piping: 5m, level difference: 0m. Data for
standard efficiency series. Nominal air flow rate, ESP 30 Pa.
(2) Nominal heating capacities are based on: indoor temperature: 20°CDB, outdoor temperature: 7°CDB, 6°CWB, equivalent refrigerant piping: 5m, level difference: 0m. Data for
standard efficiency series. Nominal air flow rate, ESP 30 Pa.
(3) Actual number of units depends on the indoor unit type (VRV DX indoor, etc.) and the connection ratio restriction for the system (being; 50% ≤CR ≤130%).
(4) Refer to refrigerant pipe selection or installation manual
(5) In accordance with EN/IEC 61000-3-12, it may be necessary to consult the distribution network operator to ensure that the equipment is connected only to a supply wih Ssc ≥
minimum Ssc value
The sound power level is an absolute value indicating the power which a sound source generates.
Sound pressure level is a relative value, depending on the distance and acoustic environment. For more details, please refer to sound level drawings. Nominal air flow rate, ESP 60 Pa.
Sound values are measured in a semi-anechoic room.
Contains fluorinated greenhouse gases
