A sense of responsibility

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 VRV III delivers highly efficient performance, contributing to high Energy savings.

Achieving a higher COP

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.

• * Cooling operating conditions: Indoor temp. of 27 °C DB, 19.0 °C WB, and outdoor temp. of 35 °C DB.
• * Heating operating conditions: Indoor temp. of 20 °C DB, and outdoor temp. of 7 °C DB, 6 °C WB.

Compliant with the RoHS Directive

We have been making efforts to facilitate the transition to using RoHS Directive^*-compliant materials for system parts.

^*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.

Double backup operation in compressors and units

• *1 Possible only with single outdoor unit systems that are equipped with two or more compressors. Local setting of the outdoor unit is necessary.
• *2 For systems composed of two or more outdoor units.

Less chances of refrigerant leakage

Conventionally, shutoff valve connections are flanged or flared. In the VRV III system, the connections for all outdoor units are brazed, meaning less chance of refrigerant leakage.
