에어컨의 쾌적지수 운전방법Comfort index operation method of air conditioner

본 발명은 냉방부하에 따라 압축기의 운전주파수를 조절하여 냉방능력을 가변할 수 있는 인버터 에어컨에 관한 것으로, 특히 외기온도의 변화에 따라 최상의 쾌적지수를 판단하고 이에 따른 여러 가지 모드를 사용자 선택에 의해 운전하는 인버터 에어컨의 쾌적지수 운전방법에 관한 것이다.The present invention relates to an inverter air conditioner capable of varying the cooling capacity by adjusting the operating frequency of the compressor according to the cooling load, in particular, to determine the best comfort index according to the change in the outside air temperature and various modes according to the user selection It relates to a comfort index operation method of the inverter air conditioner to operate.

종래에는 사용자가 외기온도를 감안하여 스스로 쾌적한 상태라고 판단하는 희망온도를 설정할 경우 에어컨에서는 현재온도와 희망온도의 차이를 보상하기 위해 임의적으로 풍량을 조절하여 에어컨을 가동시키는 방식으로 쾌적한 환경을 유지시키고 있지만 이러한 방법은 사용자가 설정한 풍량으로 운전하기 때문에 실내온도 변화에 따른 쾌적지수변화를 고려하지 못하고 있다.Conventionally, when a user sets a desired temperature to determine a comfortable state in consideration of the outside temperature, the air conditioner maintains a pleasant environment by arbitrarily adjusting the air volume to compensate for the difference between the present temperature and the desired temperature. However, this method does not consider the change of the comfort index according to the change of the room temperature because it operates with the air volume set by the user.

쾌적지수는 현재 환경의 온도, 습도, 기류, 복사온도와 인간의 활동량, 착의량의 조합에 대해 쾌적도를 정량적으로 평가하여 춥지도 덥지도 않는 쾌적한 상태로써 근래에는 냉방/난방 운전시 체감온도와 설정온도 등의 운전조건에 따라 에어컨의 냉방능력/난방능력을 효과적으로 조절하여 주는 주파수 변환장치를 이용하여 절전운전 및 인체의 냉온 쾌적지수를 만족하는 인간 감성위주의 쾌적한 냉방/난방을 제공하는 쾌적지수가 적용된 인버터 에어컨이 제품화 되고 있다.The comfort index is a pleasant condition that is neither cold nor hot by quantitatively evaluating the comfort level based on a combination of temperature, humidity, airflow, radiation temperature, human activity, and clothing amount of the current environment. Comfort index that provides comfortable cooling / heating for human emotion that satisfies power-saving operation and human body's cold / cool comfort index by using frequency converter that effectively adjusts cooling / heating capability of air conditioner according to operating conditions such as set temperature. Inverter air conditioners are being commercialized.

그러나 쾌적지수는 계절마다 또는 시간대 별로 내부나 외부 조건에 의해 변화하기 때문에 이에 따른 다양한 모드를 선택할 수 있어야 하지만 쾌적지수를 적용한 에어컨에서는 이러한 요구조건을 만족시키지 못하고 있다.However, since the comfort index changes according to internal or external conditions according to seasons or time zones, various modes must be selected. However, the air conditioner using the comfort index does not satisfy these requirements.

본 발명은 이러한 점을 감안하여 안출된 것으로, 특히 사용자가 원하는 시간대별로 다양한 쾌적지수 테이블을 제공하여 사용자로 하여금 쾌적지수 선택영역을 넓힐 수 있도록 하는 인버터 에어컨의 쾌적지수 운전방법을 제공하는데 목적이 있다.The present invention has been made in view of this point, and an object of the present invention is to provide a comfort index operation method of the inverter air conditioner that enables the user to widen the comfort index selection area by providing various comfort index tables for each desired time period. .

상기 목적을 달성하기 위한 본 발명은 인버터 에어컨에 있어서, 사용자가 요구하는 시간별 쾌적지수에 대한 키신호를 입력할 경우 해당 키신호에 대응하는 시간대별로 온도를 검출하는 온도검출단계와; 상기 온도검출단계에서 검출된 시간대별 온도를 세분화하고 그에 따른 쾌적지수 테이블을 작성하는 쾌적지수 테이블작성단계와; 사용자가 해당 쾌적지수 테이블을 선택할 경우 선택된 모드에 해당하는 쾌적운전을 실행하는 모드운전단계;의 루틴을 수행하여 사용자의 쾌적지수별 선택영역을 넓힐 수 있도록 한다.In order to achieve the above object, the present invention provides an inverter air conditioner, comprising: a temperature detecting step of detecting a temperature for each time zone corresponding to a key signal when a user inputs a key signal for a comfort index for each time required by a user; A comfort index table creating step of subdividing the temperature for each time zone detected in the temperature detection step and creating a comfort index table according to the temperature; When the user selects the corresponding comfort index table, the user can expand the selection area for each user's comfort index by performing the routine of the mode operation step of executing comfort operation corresponding to the selected mode.
