Comfortable operation apparatus and method for air conditioner

Abstract

An apparatus and a method for controlling comfortable operation of an air conditioner are provided to control the operation frequency of a compressor and the rotational speed of an indoor fan by calculating a sensible temperature according to the temperature and wind speed of discharged air, in order to control the discharged air temperature within a comfortable temperature range. A method for controlling comfortable operation of an air conditioner includes the steps of: determining whether the air conditioner is in the comfortable mode; calculating a sensible temperature in a predetermined manner if the air conditioner is in the comfortable mode; and comparing the calculated sensible temperature with a predetermined comfortable temperature and performing the comfortable operation if the sensible temperature is not within the comfortable temperature range. Even the discharged air direct contacts with the human body, the human will not feel unhappy. The comfort air is always provided to prevent air-condition disease.

Description

technical field [0001] The present invention relates to an appropriate operation control method and device of an air conditioner, in particular to a suitable operation control device and method for an air conditioner for controlling the temperature of the discharged air in a comfortable temperature range. Background technique [0002] Current air conditioners include a cooling device that cools indoor hot air and supplies it to the room, a heating device that heats indoor cold air and supplies it to the room, and some that combine the above-mentioned cooling function and heating function. The cooling and heating device even includes a cleaning function to purify polluted indoor air. [0003] Generally, an air conditioner that controls the frequency of the compressor to realize cooling and heating functions, for example, Korean Laid-Open Patent Publication No. 1999-0069705. [0004] In the air conditioner described in the bulletin, the compressor fre...

Problems solved by technology

Also, when the indoor temperature is close to the set temperature, the frequency of the compressor is controlled at a low frequency, because the cooling or heating has reached a certain state, so it is controlled to reduce its operating performance

[0007] However, the existing air conditioners as mentioned above do not consider the actual discharged air temperature, and only use the indoor temperature and the set temperature as a benchmark to control the frequency of the compressor to rise (UP) / fall (DOWN) (such as the frequency conversion type ) or the compressor is controlled ON / OFF (such as fixed speed type), so that the actual discharge air temperature is discharged as superheated or subcooled, which may cause unpleasant sensations

[0008] Moreover, since the exhaust air temperature during cooling is very low (about 13°C under standard conditions of 27°C), in fact, when the people in the living room directly contact the cold air discharged by the indoor unit, not only the people who are close to the indoor unit will not only If you feel cold or feel uncomfortable due to local skin temperature differences, etc., you may also suffer from a cold or air-conditioning disease in severe cases
