1.1 GENERAL INFORMATION

1.1.1 Specific features

The “Mitsubishi Daiya” room air-conditioner: SRK series are of split and wall mounted type and the unit consists of indoor unit and

outdoor unit with refrigerant precharged in factory. The indoor unit is composed of room air cooling or heating equipment with opera-

tion control switch and the outdoor unit is composed of condensing unit with compressor.

(1) Inverter (Frequency converter) for multi-steps power control

¡Heating/Cooling

The rotational speed of a compressor is changed in step in relation to varying load, to interlock with the indoor and outdoor

unit fans controlled to changes in frequency, thus controlling the power.

¡Allowing quick heating/cooling operation during start-up period. Constant room temperature by fine-tuned control after the

unit has stabilized.

(2) Fuzzy control

¡Fuzzy control calculates the amount of variation in the difference between the suction air temperature and the setting tem-

perature in compliance with the fuzzy rules in order to control the air capacity and the inverter frequency.

(3) Remote control flap

The flap can be automatically controlled by operating wireless remote control.

¡Natural flow (AUTO): Flap operation is automatically control.

¡Swing: This will swing the flap up and down.

¡Memory flap: Once the flap position is set, the unit memorizes the position and continues to operate at the same position from

the next time.

(4) Self diagnosis function

¡We are constantly trying to do better service to our customers by installing such judges that show abnormality of operation as

follows. (See Page 39)
