World’s Best Class Energy Savings Greater Installation Flexibility Improved Operation Control New large-diameter propeller fan (flash wing fan) The concave leading edge of the fan blades reduces flow interference between adjacent blades. Enlarged fan diameter ö630¨ ö710 Concave leading edge Outdoor heat-transfer - Compact heat-transfer tube with intakes on four sides. - Heat-transfer tube with improved heat-transfer coefficient of the inner surface. Configuration of the finned heattransfer tube Twin-rotary DC compressor Two DC twin-rotary compressors (dual configuration) are equipped per...

Reliability With dual-rotation, the load is distributed more evenly — this means that the operating sequence of the outdoor units and the individual compressors is rotated to spread the operating hours more evenly. As the compressors are all inverter driven, power surges are eliminated. Over- or under-utilisation of power, typical for non-inverter compressors is eliminated, and there is no on/off power surge as the system adjusts to the demand required by the occupant or system. The use of inverter compressors reduces the risk of compressor failure, more common in standard non-inverter...

Greater Installation Flexibility Farthest equivalent length: 175 m Maximum actual length: 150 m Maximum length from first branch: 65 m Maximum indoor difference: 30 m Maximum height difference - Outdoor unit is higher than indoor unit: 50 m Outdoor unit is lower than indoor unit: 40 m The pipe runs for the SMMS have been extended to offer greater application flexibility. Flexible branching The versatility of the SMMS means that virtually any imaginable configuration of the refrigerant Y-type branches and/ or header piping can be used in an application to give the shortest, most...

World’s Best Class Energy Savings Greater Installation Flexibility Improved Operation Control Up to 48 units can be connected at up to 135% outdoor unit capacity in a single cooling system. - Allows smooth response to floors with small rooms and tenants who change layouts often. Wide variety in our indoor unit line-up World-class line-up of 14 types of indoor units. Up to 48 indoor unit connections 30 m Height between indoor and outdoor units (Outdoor unit higher than indoor unit) World’s Top Class 10

Improved Operation Control Optimal refrigerant control – When a multiple number of indoor units are connected, an insufficient or excess amount of refrigerant may be supplied to indoor units depending on the difference in length of the connection pipe from the outdoor unit. – This is caused by pressure loss and heat leaks as the refrigerant travels through the pipes, resulting in incorrect amounts of refrigerant being supplied to the indoor units. – Optimal refrigerant control uses a multiple number of refrigerant sensors to detect the air conditioning status of each indoor unit and control...
