RVR-С-Im280-D2
- Maximum number of outdoor units connectable: 4
- Maximum total power of the system: 200 kW
- Maximum number of indoor units connectable: 64
- DC Inverter Compressor + Scroll Constant Compressor, highly efficient at low rotation frequencies
- R410A HFC refrigerant
- Fan with direct current motor that allows a consumption reduction of about 50% and a speed modulation up to 16 steps in spite of the usual 4 steps of the alternate current motors; this performance increases the efficiency of the thermodynamic system which is able to best adapt to the variations of temperature and thermal load of the rooms
- The use of a special oil sensor allows, for the first time in the world, to keep under control the lubrication of the mechanical parts of the compressor
- Special air intakes allowed to unify the dimensions of the units, making easier the closing up for multiple installations in which two units can be placed at a distance of only 20 cm one from the other, the smaller distance available
- Low sound level thanks to a special fan made of resin and a particular resin grille, designed and used for these units in order to minimize air pressure drops
- New high efficient heat exchanger with three-way suction, divided in two sections with double control of defrosting cycle
- Pressure control automatic and by software on PC
- Equipped with fault-tolerant system granting in multiple installations the operation of the air conditioning system even in case of total stop of one condensing unit
- Support to long-life system that, in multiple installations, allows a cyclic use of the condensing units, granting a balance of the compressors activity
- Wide range of outdoor air temperature: from –5 °C до +48 °C in cooling mode and from –20 °C до +27 °C in heating mode
- Maximum length of the refrigerant circuit extended to 500 m
- The refrigerant circuit doesn’t require distribution apparatus downstream of the unit as it can be realized with a tree structure using only the special distributor accessories; this feature facilitates any type of system widening, by adding both outdoor and indoor units
- Three-phase auto sense power supply 380–415/3N/50Hz
