1.1 GENERAL INFORMATION
1.1.1 Specific features
(1) A new refrigerant, R410A, which causes no damage to the earth’s ozone layer, is used. R410A is a pseudoazeotropic refrigerant, so
there is little formation of separate vapor and liquid layers, and it is possible to add refrigerant on-site.
(2) Less refrigerant charge amount due to use of double phase refrigerant flow system. The total refrigerant charge amount has been
reduced by more than 50%.
(3) The microcomputer chip is installed in the indoor unit and outdoor unit. There is no need for the unit to communicate between the
outdoor and indoor units so the unit is more resistant to electromagnetic noise thus the incidence of microcomputer malfunction
has been reduced. The compressor in the outdoor unit has its own self protection function, that reacts according to anomalous high
pressure and excessive high temperature.
(4) There are only three power lines between the outdoor and indoor unit. One cabtyre cable with 3 wires encased in one sheath is
enough for conducting the wiring work between the outdoor unit and the indoor unit. This contributes to simpler wiring work in the
field.
(5) All air supply ports have auto swing louvers. (Only case of FDTC, FDT, FDEN and FDKN models). The indoor fan motor has
three speeds of high, medium and low.
(6) All models have service valves protruding from the outdoor unit for faster flare cannection work in the field.
(7) Compared to the previous models, a single fan is used in the FDCVA402 ~ 602 outdoor unit models, resulting in markedly reduced
weight and greater compactness. In addition, use of an inverter makes these units much more economical compared to the previous
fixed speed units.
