  • An air conditioner is an appliance that cools or heats an indoor space.
  • the air conditioner includes a compressor, an expanding device, an indoor heat exchanger, and an outdoor heat exchanger that constitute a heat-exchange cycle.
  • the indoor space is cooled or heated by the heat exchange between a refrigerant and indoor or outdoor air passing through the indoor and outdoor heat exchangers.
  • FIG. 1 is a view illustrating a typical air conditioner.
  • an indoor heat exchanger for air-conditioning an indoor space is provided in an indoor unit 1.
  • the indoor unit 1 is provided with an air inlet 2 for introducing indoor air and an air outlet 3 for discharging the air introduced through the air inlet 2 and heat-exchanging with the indoor heat exchanger.
  • An input unit 4 for receiving manipulation signals for the air-conditioning of the indoor space is provided in the indoor unit 1.
  • components for air-conditioning the indoor space such as a compressor and an outdoor heat exchanger, are provided in the outdoor unit 7.
  • GB 2 260 830 A discloses that an air source discharges air to a plurality of users.
  • the air source blows gentle intensity airflow to a user who is close to the air source and strong intensity airflow to a user who is far from the air source.
  • An object of the present invention is to provide a method for controlling an air conditioner, which can enhance learning efficiency of a learner.
  • the power of concentration of the learner is enhanced and thus the learning efficiency can be improved.
  • FIG. 2 is a diagram of an air conditioner that is controlled by an air conditioner controlling method of an embodiment
  • FIG. 3 is a graph illustrating a temperature variation of an indoor space according to an embodiment.
  • an air conditioner includes an air-conditioning unit 10, an input unit 20, a location detecting sensor 30, and a control unit 40.
  • the air-conditioning unit 10 functions to control indoor air.
  • the input unit 20 receives manipulation signals of the air-conditioning unit 10 and the location detecting sensor 20 detects a location of a user (i.e., a learner) located in the indoor space.
  • the control unit 40 controls the air-conditioning unit 10 according to the signal input to the input unit 20 and the learner s location detected by the location detecting sensor 30.
  • the air-conditioning unit 10 includes a variety of components for controlling the indoor air. That is, the air-conditioning unit 10 includes components constituting a heat exchange cycle, such as a compressor, an indoor heat exchanger, and an outdoor heat exchanger. As shown in FIG. 1 , the indoor and outdoor units may be separately provided or integrated with each other, the air-conditioning unit 10 for cooling the indoor air further includes a blower fan (not shown) for directing the indoor air heat-exchanging with the refrigerant circulating the evaporator to the indoor space and a wind direction controller (not shown) such as a louver for adjusting a blowing direction of the air directed to the indoor space by the blower fan.
  • a blower fan not shown

  • the control unit 40 controls the air-conditioning unit 10, in more detail, a wind direction adjusting member in the learning preparation step A, learning steps B and D, break step C, and learning finish step E such that the air for cooling the indoor space, i.e., cool air is generated in the form of a direct wind that is directly directed toward the learner who is detected by the location detecting sensor 30 or an indirect wind that is indirectly directed toward the learner.
  • the control unit 40 controls the wind direction adjusting member such that the direct wind is generated in the learning preparation step A and learning steps B and D.
  • the control unit 40 controls the wind direction adjusting member such that the indirect wind is generated in the break step C and learning finish step E.
  • the learner By directly directing the air toward the learner in the learning preparation step A, the learner can quickly feel that the indoor space is cooled. By indirectly directing the air toward the learner in the learning steps B and D, the learner can feel comfort and thus the power of the concentration of the learner can be enhanced. In the break step C and learning finish step E, the indirect wind can allow the learner to take a break or finish the learning in a state where the power of the concentration is relatively reduced.
  • FIG. 4 is a flowchart illustrating an air-conditioning process by an air conditioner controlling method of an embodiment.
  • the control unit 40 controls such that the air-conditioning unit 10 operates for an initial step A (S13). Therefore, the indoor space is air-conditioned by the direct wind of the learning preparation air-conditioning temperature T1, i.e., a temperature equal to or greater than 24°C or less than 28°C, preferably 26°C, by the air-conditioning unit 10.
  • the control unit 40 determines if the learning preparation air-conditioning time t1 has elapsed after the initial step A starts (S15). When it is determined that the learning preparation air-conditioning time t1 has elapsed, the control unit 40 controls such that the air-conditioning unit 10 operates for the learning step B (S17). Accordingly, the indoor space is air-conditioned by the direct wind of the learning air-conditioning temperature T2, i.e., a temperature equal to or greater than 22°C and less than 26°C, preferably 24°C, by the air-conditioning unit 10.
  • the control unit 40 determines if the learning air-conditioning time t2 has elapsed after the learning step B starts (S 19). When it is determined that the learning air-conditioning time t2 has elapsed, the control unit 40 controls such that the air-conditioning unit 10 operates for the break step C (S21). Accordingly, the indoor space is air-conditioned by the indirect wind of the break air-conditioning temperature T3, i.e., a temperature equal to or greater than 23°C and less than 27°C, preferably 25°C, by the air-conditioning unit 10.
  • control unit 40 determines if the break air-conditioning time t3 has elapsed after the break step C starts (S 15). When it is determined that the break air-conditioning time t3 has elapsed, the control unit 40 controls such that the air-conditioning unit 10 operates for the learning step D (S25).
  • control unit 40 determines if the learning air-conditioning time t4 has elapsed after the learning step D of Step 25 starts (S27). When it is determined that the learning air-conditioning time t4 of Step 27 has elapsed, the control unit 40 determines if the repetition number of the learning step-break step-learning step exceeds the preset number (S29).
  • the control unit 40 controls such that the air-conditioning unit 10 operates for the learning finish step E (S31). Further, the control unit 40 determines if the learning finish air-conditioning time t5 has elapsed after the learning finish step E starts. When it is determined that the learning finish air-conditioning time t5 has elapsed, the learning mode is finished. However, when it is determined that the repetition number of the learning step-break step-learning step does not exceed the preset number in Step 29, the control unit 40 controls the air-conditioning unit to repeat Steps 21 to 27.
  • the direct and indirection winds are alternately repeated and thus the force of the concentration of the learner is enhanced. Therefore, it can be expected that the learner can more efficiently learn.
