Daikin BYM9 Outdoor Heat Pump Unit (Outdoor Unit Only)

Offers a wide variety of new functions that benefit everyone involved. VRV R series enables flexibility through simultaneous cooling and heating operation with a single VRV system. By recovering heat, it is possible significantly to reduce power consumption. VRV R series adopt a new casing to realise a single module of up to 24 class. In addition, the new models have achieved significant energy savings with improved technology. The operating performance has been improved in all directions by introducing unique ideas, technologies and a wide variety of functions to strengthen design flexibility, easy installation and reliability. We provide higher benefits to various users related to air conditioning systems, for example, building owners, consultants, installers and even building management.

Key Features & Technology

It’s the unique features of Daikin products that makes us the world leader.

Designed for our VRV and Sky Air systems, Variable Refrigerant Temperature continuously adjusts both the inverter compressor speed and refrigerant temperature in cooling and heating, allowing our systems to meet the building load with the highest levels of seasonal efficiency at all times.

Offers advanced design and new structure with excellent workability. The larger single module casing reduces installation cost and space also. The new reinforced design of the frame structure has been strengthened to improve resistance to earthquakes and wind while protecting against falling damage.

Compact Modular Design. 22 & 24HP model sits at just 1,750mm wide x 765mm deep x 1,660mm tall representing a 4% reduction in total footprint and 11% reduction in weight compared to the 5th generation VRV Series.

Single modules starting at 8HP capacity are now available in three sizes thanks to the addition of a large capacity XL chassis with 22 & 24HP (67.0kW) capacity.

High Efficiency P-Type Compressor delivers an efficiency improvement of up to 25%* compared to 5th generation VRV Series, while VRT Smart Control ensures building comfort and low energy consumption. *At 50% part load EER

Sealed electrical box with ingress protection rating of IP55 providing high dust and moisture protection, new service window provides access to multi-functional digital display for easy commissioning and troubleshooting, and separate wiring and piping provides quick access for installation and service.

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 which is an improvement of 20m from the 5th generation model.

VRV Multi Branch Selector Units

Daikin heat recovery systems utilised a 3-pipe system with Branch Selector Units (BS Units) that regulate the refrigerant to each zone & allows the individual switching of indoor units between heating & cooling. The new 4 to 12 multi port models now feature improved insulation negating the need for a condensate drain connection.
