KR940020054A - Air conditioner with variable wind speed according to wind direction and control method - Google Patents

Abstract

The present invention relates to an air conditioner having a cooling, heating, or dehumidifying function. In particular, by varying the wind speed of the discharge air discharged to the discharge port according to the louver direction angle, when the user is far from the indoor unit, the wind is stronger than the set wind speed. When the user is close to the indoor unit, the wind is discharged weaker than the set wind speed, so that the air conditioner can be operated efficiently and substantially. Also, when the louver direction angle Θ is large, the discharge is performed. As the airflow reach increases, the discharge airflow can be easily transmitted to a user located far from the indoor unit. When the user is located near the indoor unit, the rotational speed of the indoor fan motor corresponds to the louver direction angle Θ. Excellent effect of less noise and less discomfort Group is an air conditioner for varying the wind speed according to the wind direction and which relates to a control method.
