for simultaneous heating and cooling
•
The KXR6 heat recovery systems offer high performance VRF for almost
every type of building, with the capacity for simultaneous heating and
cooling operations of individual indoor units. Energy efficiency is
maximised by employing DC inverter compressors ONLY, and distributing
surplus heat from cooling operations to areas where it is required (and
vice versa) resulting in COP (in cooling) from 3.7 to 4.2.
•
Connect from 50% up to 200% capacity indoor units.
•
Industry leading total piping length up to 1000m and a maximum pipe run
of 160m.

Specifications
1. The data are measured under the following conditions(ISO-T1). Cooling: Indoor temp. of 27°CDB, 19°CWB, and outdoor temp. of 35°CDB. Heating: Indoor temp. of 20°CDB, and outdoor temp. of 7°CDB, 6°CWB. Piping length is 7.5m.
2. Sound pressure level indicates the value in an anechoic chamber. During operation these values are somewhat higher due to ambient conditions.
3. [ ] : Pipe sizes applicable to European installations are shown in parentheses.
