The refrigerant volume of the complete system is calculated from the following data:
• outdoor temperature
• reference system temperatures
• reference pressure temperatures
• refrigerant density
• types and number of indoor units
When activating the refrigerant containment check, the unit switches into cooling mode and duplicates
certain reference conditions based on memory data. The result indicates whether or not refrigerant leakage
has occurred.
Refrigerant Containment Check
Restriction of Hazardous Substances in electrical and electronic equipment (2002/95/EC)
Hazardous substances include Lead (Pb), Cadmium (Cd), Hexavalent Chromium (Cr6+), Mercury (Hg),
Polybrominated biphenyls (PBB), Polybrominated diphenylether (PBDE).
Although RoHS regulations are only applicable to small and large household equipment, Daikin
environmental policy nevertheless ensures that VRVIII will be totally in line with RoHS.
RoHS Compliance
The linear VRV system makes use of a variable Proportional Integral (PI) control system which uses refrigerant
pressure sensors to give added control over inverter and ON/OFF control compressors in order to abbreviate
control steps into smaller units to provide precise control in both small and larger areas. This in turn enables
individual control of up to 60 indoor units of different capacity and type at a ratio of 50~200 % in comparison
with outdoor units capacity. 5 HP outdoor units use inverter control compressors only.VRV systems have low
running costs because it permits each zone to be controlled individually. That is, only those rooms that require
air conditioning will be heated or cooled, while the system can be shut down completely in rooms where no
air conditioning is required.

- Back up function 16
- For some applications the operating sound level of the outdoor unit might be too high vrviii super silent mode however allows the sound level to be fixed in order to avoid noise pollution 16
- In the event of a compressor malfunction the remotely controlled or field set back up function in the outdoor unit in question and also between different outdoor units will allow emergency operation of another compressor in order to maintain 8 hour maximum interim capacity 16
- Stacked configuration 16
- Step 1 fixes the operating sound value at 50dba when the sound level of an 8hp outdoor unit is fixed at 50dba it will operate at 98 of its nominal capacity step 2 fixes the operating sound value at 45dba when the sound level of the same 8hp outdoor unit is fixed at 45dba it will operate at 74 of its nominal capacity 16
- Super silent mode 16
- The adoption of a new water heat exchanger and optimization of the refrigerant control circuit has resulted in the industry s most compact and lightweight design the unit weight of 150kg and height of 1 000mm makes installation easy stacked configuration is also possible contributing further to space savings 16

- An electronic expansion valve using pid control continuously adjusts the refrigerant volume in respond to load variations of the indoor units the vrv system thus maintains comfortable room temperatures at a virtually constant level without the temperature variations typical of conventional on off control systems 22
- Less frequent start stop cycle 22
- Refrigerant recovery function 22
- Since daikin utilises small 5hp inverter compressors the influence of harmonics is less than that generated by a single large compressor 22
- Smaller compressors are cheaper and faster to replace 22
- Smart control brings comfort 22
- The refrigerant recovery function enables all expansion valves to be opened in this way the refrigerant can be drained from the piping system 22
- The technique adopted by daikin of regulating the capacity using multiple compressors clearly results in minimum switching losses and power surges because of the overlap in capacity and frequency 22
- The thermostat can control stable room temperature at 0 c from set point 22
- The use of multiple compressors by daikin also ensures a 50 standby facility 22
