Longest refrigerant piping run
6
The ability to sustain refrigerant piping in lengths up to 150m (175m equivalent), allows systems to be designed with level differences of 50m between
indoor and outdoor units and 15m between individual indoor units. Thus, even with installations in 15 storey buildings, all outdoor units can be located
at rooftop level.

In this case the outdoor unit is located above the indoor unit. If the outdoor unit is located underneath the indoor
unit the level difference is a maximum of 40m.

Short planning and design time
In conventional water systems, the size of the pipes and all auxiliary equipment must be calculated in accordance with the water flow rate.
However, using a Daikin VRV system, with innovative compressor technology, time-consuming calculations are not necessary, offering considerable
reductions in design time.
