Definitions

  • the present invention relates to temperature of air conditioner, and more particularly to a method of controlling a temperature in a room according sound volume in the room.
  • Air conditioners are widely used in air conditioning. Modern air conditioners may provide hot air and cooled air so that no matter what season it is, the air conditioner may provide a desired indoor temperature.
  • a conventional air conditioner provides user to input a setting temperature, and the air conditioner provides cooled air or hot air to change the temperature in the room to the setting temperature.
  • FIG. 1 shows a relation between the temperature in a room, which is conditioned by the conventional air conditioner, and time. The temperature is kept in constant all time.
  • FIG. 2 shows that the temperature in the room is conditioned by another type of the air conditioner. The temperature is changed in different periods of a day. For example, the temperature is higher in the nighttime than in the daytime. User may input the desired temperatures for different periods.
  • these two conventional air conditioners are running according to the setting only. Sometime, it will waste the energy because the conditions in the room changed, such as people leaving the room, but the sir condition still is running according to the old setting.
  • the primary objective of the present invention is to provide a method controlling a temperature in a room, which may reduce the unnecessary power consumption.
  • the present invention provides a method of controlling a temperature in a room, wherein an air conditioning unit is provided to change a temperature in the room, and the method includes the following steps:
  • a power consumption of the air conditioning unit to keep the temperature in the second temperature is lower than a power consumption of the air conditioning unit to keep the temperature in the first temperature.
  • the method of the present invention may reduce the unnecessary power consumption when there is nobody in the room.
  • FIG. 1 shows a relation of the temperature and time of the conventional air conditioner
  • FIG. 2 shows a relation between the temperature and time of another type of the conventional air conditioner
  • FIG. 3 is a block diagram of the air conditioner of a preferred embodiment of the preferred embodiment of the present invention.
  • FIG. 4 is a flow chart of the method in the cooling mode of the preferred embodiment of the present invention.
  • FIG. 5 shows a relation of the temperature and time, showing the temperature change in the constant-temperature type of the cooling mode of the preferred embodiment of the present invention
  • FIG. 6 shows a relation of the temperature and time/volume, showing in the temperature change in the variant-temperature type of the cooling mode of the preferred embodiment of the present invention
  • FIG. 7 is a flow chart of the method in the heating mode of the preferred embodiment of the present invention.
  • FIG. 8 shows a relation of the temperature and time, showing the temperature change in the constant-temperature type of the heating mode of the preferred embodiment of the present invention.
  • FIG. 9 shows a relation of the temperature and time/volume, showing in the temperature change in the variant-temperature type of the heating mode of the preferred embodiment of the present invention.
  • FIG. 3 shows a flowchart of a method of controlling a temperature of the preferred embodiment of the present invention.
  • An air conditioning system is provided to change the temperature, which includes a setting unit 10 and an air conditioning unit.
  • the air conditioning unit includes a cooling module 20 and a heating module 30 .
  • the setting unit 10 includes an electric control module 12 , an audio sensor 14 , and a control panel 16 .
  • the audio sensor 14 and the control panel 16 are electrically connected to the electric control module 12 respectively.
  • the audio sensor 14 is a microphone in the present invention to sense a volume of sound in a room and to obtain a sensed volume.
  • a user may operate the control panel 16 to input some settings, including selecting a cooling mode or a heating mode, and inputting a first temperature T1 and a volume value dB, for controlling the air conditioning system (referring to FIG. 5 ).
  • the cooling module 20 is activated to lower the temperature
  • the heating module 30 is activated in the heating mode to raise the temperature.
  • the electric control module 12 respectively controls the cooling module 20 and the heating module 30 to provide hot air or cooled air.
  • the first temperature T1 is a desired temperature in the room, and is the temperature that the air conditioning unit should give.
  • the volume value dB is given by user, which is the critical value to determine if there is anyone in the room. If a volume sensed by the audio sensor 14 is higher than the volume value dB, it indicates that there is at least one man in the room. On the contrary, it indicates nobody in the room when a volume sensed by the audio sensor 14 is lower than the volume value dB. It should be aware of the background volume in the adjustment of the volume value dB.
  • FIG. 4 shows the flowchart of the temperature controlling method when the air conditioning unit is switched to the cooling mode.
  • the temperature controlling method includes the following steps:
  • the electric control module 12 controls the cooling module 20 to provide cooled air to lower a temperature in a room to the first temperature T1, and keeps the temperature in the first temperature T1.
  • the electric control module 12 controls the audio sensor 14 to sense a volume of sound in the room and to obtain a sensed volume, and then the sensed volume is compared with the volume value dB.
  • the electric control module 12 controls the cooling module 20 to keep the temperature in the room in the first temperature T1 while the sensed volume is higher than the volume value dB.
  • the electric control module 12 controls the cooling module 20 to raise the temperature in the room to a second temperature T2. It may reduce the power consumption of the cooling module 20 .
  • the change of the cooling module 20 will be activated only when the volume sensed by the audio sensor 14 is lower than the volume value dB for the first waiting time. The reason of it is to avoid the cooling module 20 from being changed repeatedly while people only leave the room temporally.
  • the electric control module 12 controls the cooling module 20 to raise the temperature in the room to a third temperature T3.
  • the temperature is rising from the second temperature T2 to the third temperature T3 in tiers.
  • the temperature in the room is raised for predetermined degrees per a third waiting time t3. If the sensed volume is higher than the volume value dB, which means somebody comes back, the electric control module 12 controls the cooling module 20 to lower the temperature in the room back to the first temperature T1.
  • FIG. 5 shows that the first temperature T is set to a constant temperature (23° C.).
  • a volume sensed by the audio sensor 14 is greater than the volume value dB, and the electric control module 12 controls the cooling module 20 to keep the temperature in the room in 23° C. (the first temperature T1).
