## Abstract

A method for controlling an air conditioner is provided. The method includes calculating an index weight outdoor average temperature by calculating outdoor temperature data over a predetermined period, acquiring position information in which the air conditioner is installed, selecting an appropriate climatic model according to the position information, calculating a comfortable temperature of the day by substituting the index weight outdoor average temperature to the climatic model, setting the comfortable temperature as an indoor target temperature, and controlling a cooling or a heating of the air conditioner so that the indoor temperature reaches the indoor target temperature.

## Claims

### Claim 1

A method for controlling an air conditioner, the method comprising:
calculating an index weight outdoor average temperature by calculating outdoor temperature data over a predetermined period;
acquiring position information in which the air conditioner is installed;
selecting an appropriate climatic model according to the position information;
calculating a comfortable temperature of the day by substituting the index weight outdoor average temperature to the climatic model;
setting the comfortable temperature as an indoor target temperature; and
controlling a cooling or a heating of the air conditioner so that the indoor temperature reaches the indoor target temperature.

### Claim 2 (depends on 1)

The method as claimed in claim 1, wherein the selecting of the climatic model comprises selecting the climatic model corresponding to the position information among a plurality of climatic models which are predetermined for geographical positions of the world.

### Claim 3 (depends on 2)

The method as claimed in claim 2, wherein the calculating of the comfortable temperature comprises:
adding a predetermined temperature constant to a value obtained by multiplying a predetermined temperature coefficient by the index weight outdoor average temperature; and
setting the temperature coefficient and the temperature constant to correspond to each of the plurality of climatic models.

### Claim 4 (depends on 3)

The method as claimed in claim 3, wherein the plurality of climatic models include first to eighth climatic models, and
the first climatic model is a west coast marine climate, the second climatic model is a continental subarctic climate, the third climatic model is a humid mid latitude climate, the fourth climatic model is a semi arid climate, the fifth climatic model is a tropical savanna climate, the sixth climatic model is a humid subtropical climate, the seventh climatic model is a Mediterranean climate, and the eighth climatic model is a hot arid climate.

### Claim 5 (depends on 4)

The method as claimed in claim 4, wherein the first to eighth climatic models each include first to eighth temperature coefficients and first to eighth temperature constants.

### Claim 6 (depends on 5)

The method as claimed in claim 5, wherein the first and second temperature coefficients are each in a range of 0.2 to 0.4,
the first temperature constant is in a range of 16 to 18, and
the second temperature constant is in a range of 18 to 22.

### Claim 7 (depends on 5)

the third temperature constant is in a range of 18 to 22, and
the sixth temperature constant is in a range of 16 to 20.

### Claim 8 (depends on 5)

The method as claimed in claim 5, wherein the fourth, seventh, and eighth temperature coefficients are each in a range of 0.3 to 0.5,
the fourth temperature constant is in a range of 13 to 17, and
the seventh and eighth temperature constants are each in a range of 15 to 19.

### Claim 9 (depends on 5)

the fifth temperature constant is in a range of 16 to 20.

### Claim 10 (depends on 5)

The method as claimed in claim 5, wherein the first to eighth climatic models each correspond to the geographical positions of the world according to a Koppen-Geiger climate classification.

### Claim 11 (depends on 3)

The method as claimed in claim 3, further comprising measuring outdoor relative humidity,
wherein the calculating of the comfortable temperature further includes adding a value obtained by multiplying the outdoor relative humidity by a predetermined humidity coefficient, and
wherein the humidity coefficient is set to correspond to each of the plurality of climatic models.

### Claim 12 (depends on 1)

The method as claimed in claim 1, wherein the acquiring of the position information comprises using a global positioning system (GPS) sensor of the air conditioner.

### Claim 13 (depends on 1)

The method as claimed in claim 1, wherein the acquiring of the position information comprises inputting the position information through an interface of the air conditioner.

### Claim 14 (depends on 1)

The method as claimed in claim 1, wherein the controlling of the cooling or the heating of the air conditioner comprises:
determining whether or not the indoor temperature is matched to the indoor target temperature; and
when the indoor temperature is not matched to the indoor target temperature, controlling a cooling or heating operation so that the indoor temperature reaches the indoor target temperature.

### Claim 15 (depends on 1)

The method as claimed in claim 1, wherein the calculating of the index weight outdoor average temperature comprises obtaining the index weight outdoor average temperature by adding a value obtained by multiplying an outdoor average temperature of the previous day of a calculation day of the outdoor average temperature by a first weight index to a value obtained by multiplying an index weight outdoor average temperature of the previous day by a second weight index greater than the first weight index.
