This is the first full VRV model change in 7 years. Significant improvement in total performance.
Optimal supply exactly meets the required capacity of indoor units
Reduces compressor load and minimizes operation loss so it is energy saving.
Controls capacity according to load to ensure a constant room temperature for greater comfort.
Design flexibility is further improved by simultaneous extension of height difference, improved from 90 m to 110 m, and equivalent length (up to 190 m).
Height difference extension Max. 110 m
For height differences exceeding 50 m with the outdoor unit above the indoor unit and 40 m with the outdoor unit below, the main piping liquid piping size must be increased.
Equivalent length extension Max. 190 m
When the equivalent piping length from outdoor unit to indoor unit is 90 m or more, be sure to increase the main piping liquid piping size.
* In addition to increasing the size of the main pipe, there are other piping restrictions regarding height difference extension and equivalent length extension.
Piping branch by REFNET joint is possible downstream of REFNET header.
The indoor unit arrangement can be more flexible.
