Conclusion:

Item Haier Fujitsu ConclusionLarge capacity Outdoor units from 8HP to 48Hp

,each 2 hp have one model totally22models;

Outdoor units from 8HP to 42Hp ,totally 16 models

Haier have more choice thanFujitsu for outdoor units

High performance Haier use PURE DC invertersystem design ,high efficiency andsave energy cost thanconventional VRV system;

Fujitsu use DC inverter +constantspeed system ,cost operationenergy

Haier units can save 30% that ofthe energy than Fujitsu units (take8HP outdoor units as an example)

Indoor units Haier have good advantage in 4-way cassette type and some bigsize wall-mounted type,10 series42 models

Have good advantage inConvertible type and ceilingconcealed duct type ,12 series 54models

Haier has less models than Fujitsu

Design and installation Haier units can use small size pipeand big capacity installation ;

Need less refrigerant than Fujitsu

Pipe size is bigger ;

Need more refrigerant quantity;

Haier save 10% cost than Fujitsuduring installation;
