Unique 2-pipe system

The R2-Series was developed to encourage energy-conserving and eco-friendly systems for use in modern buildings. Airtight building envelopes that permit little air exchange call for modern and energy-efficient air conditioning. This means that surplus heat energy, from server rooms for instance, is carried to rooms that are to be heated. This sensible relocation of energy is ideal for buildings with large-scale façade glazing and building sides facing southwest.

The R2-Series is the only heat recovery system worldwide that permits simultaneous heating and cooling with only two pipes. With water-cooled WR2 systems in particular, the recovered heat is released into a water network and stored or used elsewhere in conjunction with other WR2 systems.

The central component of any R2 system is the BC controller. This is a refrigerant distributor which, together with the outdoor unit, forms a single refrigeration and control entity and thus permits heat recovery. By means of the BC controller, up to 50 indoor units can be connected to an outdoor unit, and with only 2 pipes*.

Thanks to the use of hypermodern inverter technology, compressor frequency in the outdoor unit can be reduced to as low as 15 Hz. The capacity range of all connected indoor units can be from 50 to 150%. For customized solutions, a connection index of 200% is possible on request.

As a result of the integrated fuzzy logic control, the room temperature of all indoor units can be adjusted precisely to the requirements of the particular user. In automatic mode, there is automatic switchover between heating and cooling according to the individually set temperature – for more comfortable conditions with extremely simple control.

Efficiency and function are thus ensured and already have a record of success going back 20 years.
