System configuration example
Flexible systems for small- and
medium-size buildings air conditioning
Space saving design and long piping design allow for
flexible installation on the roofs or balconies of small-
and medium-size buildings.
Multiple indoor units of various capacities and types
can be connected.
High Energy Efficiency
Heat pump inverter control is used to achieve an
efficient cooling and heating operation in any indoor
unit combination.
Advanced high efficiency technology
High EER / COP
The building load is in the range of 40 % to 80%. Therefore, most
air conditioners do not operate at maximum load, but operate at
low to medium loads. Especially, for multi system, operation
performance at partial load is important because air conditioners
do not always operate at full load all the time. Aiming at energy
saving performance matched to actual operation, Fujitsu General
has developed a high performance air conditioner corresponding
not only during the rated performance at 100% load, but also at
low to medium load
High part load performance (6HP class)

Efficiency in all load regions is good. Especially good
performance from low to medium at normal operation.
Large propeller fan
High performance and low noise realized by
large propeller and optimization of angle.
DC inverter control
Efficiency is improved by mounting of new
active filter module.
Subcool heat exchanger
Cooling performance is improved by
mounting of dual tube heat exchanger.
