&nbsp;■ Title

-

( Inverter model ) The outdoor unit&nbsp; keeps going on and off during its operation.

■ Problem

- Cooling

■ Symptom

-&nbsp;

The outdoor unit is not operating during&nbsp; cooling

■&nbsp;

Solution

or

Settings

-

The inverter outdoor units can enhance/ diminish the cooling performance of the appliance by controlling the rotating speed of the compressor according to the room

&nbsp;&nbsp;temperature.

&nbsp;&nbsp;

If the room temperature is much higher than the desired temperature, a lot of cooling&nbsp; is required so it increases the rotating speed of the compressor

and

&nbsp; &nbsp;

If the room temperature is a little higher&nbsp;

than the desired temperature, the rotating speed&nbsp; of&nbsp; the compressor is lowered to maintain less cooling.

method 1

-&nbsp;

When it reaches the desired temperature, the rotating speed of the compressor as well as the outdoor fan decreases (Pressure controlling method)

&nbsp;

&nbsp;&nbsp;

At this point, the compressor and the outdoor fan do not stop operating completely, but continue to operate at low speed, which is the&nbsp;reason why you may feel

&nbsp; that&nbsp; “The outdoor unit goes on and off during its operation or stops operating".

2&nbsp;

-&nbsp;When it reaches the desired temperature, the rotating speed of the compressor is reduced, but the rotating speed of the outdoor fan is maintained.

&nbsp; (step controlling method)

&nbsp;&nbsp;

At this point, the rotating speed of the compressor reduces while the rotating speed of the outdoor fan is maintained which is the reason why you may feel

&nbsp; that "the outdoor unit goes on and off or stops operating"

.

※ The outdoor unit is turned off when the room temperature is lower than the desired temperature by 1°C or more.

&nbsp;&nbsp;&nbsp; When there is a little difference between the room and desired temperature, the inverter saves more energy by reducing the rotating speed of the compressor

&nbsp;&nbsp;&nbsp; to maintain the desired temperature.

When it reaches the desired temperature(set temperature), it reduces the <p style="text-align: left; line-height: 80%; font-family: Arial; font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; vertical-align: baseline; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

rotating speed of the compressor.

▶

As the compressor rotating speed decreases, operation noise and vibration

&nbsp;&nbsp;&nbsp;&nbsp;are&nbsp;reduced as well.

&nbsp;&nbsp;&nbsp;&nbsp;

At this point, you may feel “The outdoor unit goes on and off during its operation

&nbsp;&nbsp;&nbsp; or stops operating

※

For inverter air conditioners, the outdoor unit does not go off even&nbsp; when it has reached the desired temperature.

&nbsp;<p style="text-align: left; line-height: 80%; font-family: Arial; font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0in; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

&nbsp;&nbsp;&nbsp;T

he appliance uses minimum&nbsp; energy required to keep the unit from turning off, and by doing to it can meet&nbsp;

and maintain the desired temperature using less power.<p style="text-align: left; line-height: 80%; font-family: Arial; font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0in; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

※

The outdoor unit may stop its operation under following situations:<p style="text-align: left; line-height: 80%; font-family: Arial; font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0in; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

1)

When the capacity of the air conditioner exceeds the covered area.</div><p style="text-align: left; line-height: 80%; font-family: Arial; font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0in; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

&nbsp;&nbsp;&nbsp; : If the capacity of the air conditioner exceeds the covered area, the room temperature drops down quickly and&nbsp;

it may cause overcooling.<p style="text-align: left; line-height: 80%; font-family: Arial; font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0in; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

&nbsp;2)

When the reset value of the desired temperature is higher than current room temperature. <p style="text-align: left; line-height: 80%; font-family: Arial; font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0in; unicode-bidi: embed; direction: ltr; language: ko; punctuation-wrap: hanging;">

&nbsp;&nbsp;temperature.

-

If the room temperature is much higher than the desired temperature, a lot of cooling&nbsp; is required&nbsp;

so it increases the rotating speed of the&nbsp; compressor

and

- If the room temperature is a little higher than the desired temperature, the rotating speed&nbsp; of&nbsp; the compressor is lowered&nbsp;

to maintain less cooling.

&nbsp;

At this point, the compressor and the outdoor fan do not stop completely, but continue to operate at&nbsp; low speed,&nbsp;&nbsp;

which is the reason&nbsp; why you may feel that&nbsp;

&nbsp;&nbsp; “The outdoor unit goes on and off during its operation or stops operating."
