Abstract
An air conditioning system and a control method thereof enables an infrared-ray detecting portion to detect the number of people and their moving area and controls the direction of a louver and an amount of air forced by a room blower fan, the swing of the louver being adjusted according to the movement state and the number of people so as to make the users feel a comfortable air conditioning environment at every area of room.
Claims12
A method of controlling an air conditioning system, said method comprising steps of:
- detecting a room temperature;
- enabling an infrared-ray detecting means to detect infrared rays in a total area divided into a predetermined number of divided areas to detect a radiation temperature of each of the divided areas for a predetermined time period;
- calculating the difference between the detected radiation temperature and the detected room temperature;
- judging whether the temperature difference is above a predetermined temperature difference and, if over a predetermined temperature difference, judging whether said detected radiation temperature is above a predetermined radiation temperature to determine the location of a person;
- determining a completion of the detection with respect to the location of a person and the total area;
- calculating the difference between the room temperature and a set temperature to determine whether the existence of a person is detected and comparing the temperature of an area in which a person is detected with the temperature of areas adjacent to the area in which a person a detected;
- and
- controlling a direction of blowing wind by a louver, an amount of blowing wind of a room blower fan and the operation of a compressor in response to results of said judging and said calculating steps.
A method of controlling an air conditioning system for detecting a room temperature, comparing the room temperature with the previously set temperature and adjusting the room temperature to the set temperature, comprising the steps of:
- detecting the existence or non-existence and the moving area of at least one person;
- calculating the difference between the room temperature and the radiation temperature emanated from a person;
- determining the radiation temperature and the location of a person;
- and
- controlling a direction and an amount of blowing wind of each of a louver and a room blower fan in at least two steps according to the number and place of said at least one person.
An air conditioning system for detecting a room temperature, comparing the room temperature with the previously set temperature and adjusting the room temperature to the setting temperature, comprising:
- means for moving toward an area divided into a predetermined number of divided areas in turn in upward, downward, leftward and rightward directions so as to detect infrared-rays emanated from a person;
- and
- means for controlling the movement of the detecting means to a predetermined divided area, determining the existence or non-existence and the movement of a person, and controlling the driving direction of a louver, an operation of a room blower fan and a compressor in response thereto.
An air conditioning control method for controlling room temperature, said method comprising the steps of:
- detecting radiation temperature for a predetermined time period in each of a plurality of areas;
- detecting an ambient temperature;
- calculating a difference between said detected radiation temperature and said ambient temperature;
- judging whether said calculated temperature difference is above a predetermined temperature difference;
- and
- controlling a direction of temperature conditioned forced air in response to a result of said judging step.
