Outdoor units designed for low-noise operation

High COPs

It has become essential for air conditioning manufacturers to develop systems that

provide high energy savings. We at Daikin have made great efforts in this field, and

the newly-developed VRVIII delivers highly efficient performance, contributing to high

energy savings.

Outdoor units created with cutting-edge technologies provide quiet operation to

increase users’ comfort.

Efficient compressor

New high-performance, low-noise scroll compressor operates at a

faster rate, reducing start-up time. This helps the unit to bring the

room temperature up to the set level quickly.

Nighttime quiet operation function

Compliant with the RoHS Directive*

We have been making efforts to facilitate the transition to using RoHS Directive*-compliant

materials for system parts.

Less chances of refrigerant leakage

Conventionally, shutoff valve connections are flanged or flared. In the VRVIII system, the connections for all

outdoor units are brazed, meaning less chance of refrigerant leakage.

* RoHS Directive

The RoHS (Restriction of Hazardous Substances (in electrical and electronic equipment))

Directive is an environmental directive enacted to regulate the use of designated chemical

substances (lead, cadmium, hexavalent chromium, mercury, polybrominated biphenyls and

polybrominated diphenylether) in electrical equipment. All household products subject to

this Directive and sold in Europe from July 1, 2006 are legally bound to comply with the

RoHS Directive.

Set on the outdoor PCB. Time of maximum

temperature is memorised. The low

operating mode will initiate 8 hours

after

the peak temperature in the daytime, and

normal operation will resume 10 hours

after

that. The operation sound level for the night

mode can be selected from 55 dB (Step 1),

50 dB (Step 2) and 45 dB (Step 3).

(For a single outdoor unit.)

Starting time and ending time can be input.

(External control adaptor for outdoor unit,

DTA104A61 or DTA104A62, and a field

supplied time clock are necessary.)

Manual mode

Mode 2.

Combination of mode 1 and 2 can be used

depending on your needs.

Combined mode

Mode 3.

*1. Determine which mode to select depending on the

climatic characteristics of each country.

*2. Initial setting. Can be selected from 6, 8 and 10 hours.

*3. Initial setting. Can be selected from 8, 9 and 10 hours.

• This function is available in setting at site.

• The relationship of outdoor temperature (load) and time shown in the

graph is just an example.

We have reached a new level of

efficiency, thanks to the new advanced

features such as the heat exchanger,

the grille and the dual DC fans.
