Description

When the following conditions are satis- fied, winding is heated by output varied by the outdoor heat exchanger temperature.

Condition 1 :

The previous operation was heating.

Condition 2 :

2 hours passed after operation stop.

Condition 3 :

The room temperature is 20°C or lower.

The indoor temperature sensor detects the room temperature.

If the detected room temperature is 20°C or lower, the outdoor heat exchanger temperature sensor detects the outdoor heat exchanger temperature. As shown in

The necessity of defrost operation is detected by the outdoor heat exchanger temperature. The conditions to detect the necessity of defrost operation differ in A, B, or C zone each. (Table 1)

<Defrost operation>

• Defrost operation in A to C zones

1)Stop operation of the compressor for 20 seconds.

2)Invert (ON) 4-way valve 10 seconds after stop of the compressor.

3)The outdoor fan stops at the same time when the compressor stops.

4)When temperature of the indoor heat exchanger becomes 38°C or lower, stop the indoor fan.

<Finish of defrost operation>

Returning conditions from defrost operation to heating operation

1)Temperature of outdoor heat exchanger rises to +8°C or higher.

2)Temperature of outdoor heat exchanger is kept at +5°C or higher for 80 seconds.

3)Defrost operation continues for 15 minutes.

<Returning from defrost operation>

1)Stop operation of the compressor for approx. 50 seconds.

2)Invert (OFF) 4-way valve approx. 40 seconds after stop of the compressor.

3)The outdoor fan starts rotating at the same time when the compressor starts.
