With the introduction of the new Air Flux series, Bosch launches an energy-efficient and convenient Variable Refrigerant Flow (VRF) system. Air Flux covers the complete product range from individual and combined outdoor units, to 13 different indoor air conditioning units and intelligent control units as well as a newly developed planning software. Accessories and spare parts complete the programme. Air Flux is suitable for mid-sized and large properties such as hotels, office buildings and public facilities.

Combining energy efficiency with a wide output range

Air Flux performs highly energy-efficiently at cooling and heating thanks to a newly developed scroll type compressor with vapour injection and plate heat exchanger used for sub-cooling. Due to improvements in the compressor, heat exchanger and cooling cycle, the new Air Flux series reaches a seasonal energy efficiency ratio (SEER) of up to 7.6. This allows a wide outdoor ambient operation range at cooling and heating. The new outdoor units operate in cooling mode at temperatures from minus five to plus 48 degrees Celsius and in heating mode at temperatures from minus 23 to plus 25 degrees Celsius. The integrated energy management system automatically adjusts the evaporation and condensation temperatures, which maximises energy efficiency and comfort during system operation. The new Air Flux series is also the VRF system with the widest output range currently on the market, reaching from 25 to 90 kilowatts. The series encompasses 13 different modules. They can be combined flexibly and in cascaded systems enable a capacity of up to 270 kW.

Intelligent controls developed by Bosch

To manage air conditioning on a mid to large scale, Bosch has developed a central controller with touch display: the Air Center Control. With the expandable module up to 256 indoor units can be monitored. The touch screen controller has been designed for facility managers of hotels, office buildings or other larger properties. Air Center Control is easy to use and includes a layout plan, a schedule as well as monitor parameters to help building managers monitor their VRF systems. The controller is compatible with the entire Air Flux series and connects via LAN, thus enabling local connectivity as well as remote access from a laptop or a PC. Remote updates can also be provided. Various gateways enable the connection to building management systems.

In addition, Bosch has transferred its residential heating expertise to the air conditioning sector by developing Air Room Control, a new wired room controller which is available in two versions: while the standard model provides convenient new functions for commercial users, the variant developed exclusively for hotels can be used in combination with power saver cards as well as door and window switches. The totally newly developed planning software “Air Select” offers precise selection options via the internet or on the PC to support planners in the early stage.

Pleasant to the eye and easy to use

Bosch provides a wide range of different indoor units thus offering the indoor unit with the right output for every application. All units feature the attractive Bosch design and are supplied in variants ranging from small units with slim dimensions to powerful devices for large rooms.
