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 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.

No lamp will flashing when the unit is operating

Low input rotary compressor with high efficiency is equipped. All operation modes can be operated from distance place by the wire-

less remote control. And also liquid crystal is used to show all kinds to operation or, off, air flow switch, operation switch, timer switch, timer set, temperature set, flap control.

Defumidifies while keeping room temperature to the thermostat setting level by M.C. thermostat.

ON timer setting for anytime during 24 (32, 40: 12) hours can be performed. OFF timer setting for favourite time can be performed. Comfortable

Cooling and Dry operation to prevent catching cold in sleep and economical operation can be performed, while raising room temperature setting during 1 hour period in steps. While COOL & DRY: When the timer is set to OFF the temperature is increased by 0.5ºC simultaneously, by 0.5ºC additionally every 30 minutes and by 1.5ºC in one hour. While HEAT: When the timer is set to OFF the temperature is decreased by 1ºC simultaneously by 1ºC additionally every 30 minutes and by 3ºC in one hour. (Heat Pump type only)

Room unit air volume can be automatically controlled step by step, according to the difference between room temperature and setting temperature.

1. Shorten pull down time for cooling/heating operation

2. Low noise level operation can performed by proper air volume.

When heating is initiated, thermostat reset, or heating resumed after defrosting, the indoor fan is automatically controlled

stop to set value in accordance with the temperature of the indoor air heat exchanger to prevent the blowing out of cold air.

The thermostat temperature setting is automatically increased by 2ºC when heating is initiated to provide faster stabiliza-

tion of room temperature. The indoor fan is stopped depending on the temp, of the indoor heat

exchanger to prevent the blowing-out of cold air when the

heating operation is stopped by thermostat or defrosting operation is started.

The change in the difference between the intake air temperature and the heat exchanger temperature causes the frost and condensation removal operation to start.

M. C thermostat improves on energy saving and comfort, by controlling room temperature with high accuracy.

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

• AUTO (Natural flow): Flap operation is automatically controlled.

• 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.

The room temperature is checked 60 minutes before the timer is at ON. Depending on the temperature at that time, the operation starets 5 to 60 minutes before the timer is at ON. We are constantly trying to do better service to our customers by installing such judges that show abnormality of each function as follows:

• Abnormality of outdoor unit:

TIMER lamp flashing.

• Abnormality of indoor fan motor:

RUN lamp flashing.

• Abnormality of heat exchanger thermistor:

RUN lamp flashing.

•

Abnormality of room temperature thermistor:

RUN lamp flashing.

1.2.5 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.

Net capacity = Capacity shown on specification ✕ Correction factors as follows. (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.

How to obtain the cooling and heating capacity

Example : The net cooling capacity of the model SRK50HA with the piping length of 15m, indoor wet-bulb temperature at 19.0˚C and outdoor dry-bulb temperature 35˚C is Net cooling capacity = 45000 ✕ 0.975 ✕ 1.0 = 4387 w

(4) Insulation of connecting portion

1) Cover the connection portion of the refrigerant piping with the pipe cover and seal them. If neglecting to do so, moisture occurs on the piping and water will drip out.

2) Finishing and fixing a) Tie up the piping with wrapping tape, and shape it so

that it conforms to which the pipe is attached.

b) Fix them with clamps as right figure.

Additional refrigerant charge

When refrigerant piping exceeds 7(40 : 7.5) m conduct additional refrigerant charge after refrigerant sweeping.

7m over 15m : Additional charge amount per meter = 20g/m

S 40 model

Max. 10m : Additional charge amount per meter = 20g/m 10m over 15m : Additional charge amount per meter = 30g/m

[Example : 50 model]

How much amount of additional charge for 15m piping?

(15 – 7)m × 20g/m = 160g 160g for additional charge

1.5.5 Test run

(1) Conduct trial run after confirming that there is no gas leaks. (2) When conducting trial run set the remote controller thermostat to continuous operation position. However when the power source

is cut off or when the unit’s operation switch is turned off or was turned to fan operation position, the unit will not go into operation in order to protect the compressor.

(3) Insert in electric plug into the electric outlet and make sure that it is not loose.

(a) When there is something wrong with the electric outlet and if the insertion of the electric plug is insufficient, there may occur

a burn out.

(b) It is very important to be careful of above when pulgging in the unit to an already furnished electrical outlet.

(4) Explain to the customer on the correct usage of the air conditioner in simple layman’s terms. (5) Make sure that drain flows properly. (6) Standard operation data
