1 GENERAL INFORMATION

1.1 Specific features

The “MITSUBISHI HEAVY INDUSTRIES, LTD” 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 operation control switch and the outdoor unit is composed of condensing unit with compressor.

(1) Remote control flap

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

¡AUTO (Natural flow) : 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.

(2) Automatic Operation

When the remote control switch is set on “auto”, it will either automatically decide operation mode such as cooling, heating and

thermal dry, or operate in the operation mode before it has been turned to automatic control.

(3) 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.

2.5 Selection chart

Correct the cooling and heating capacity in accordance with the conditions as follows. The net cooling and heating capacity can be

obtained in the following way.

(1) Coefficient of cooling and heating capacity in relation to temperatures

(2) Correction of cooling and heating capacity in relation to one way length of refrigerant piping

It is necessary to correct the cooling and heating capacity in relation to the one way piping length between the indoor and outdoor

units.

(3) Correction relative to frosting on outdoor heat exchanger during heating

In additions to the foregoing corrections (1), (2) the heating capacity needs to be adjusted also with respect to the frosting on the

outdoor heat exchanger.
