Description

  The present invention relates to temperature control of an air conditioner, and more specifically, based on detection data of current room temperature and outside air temperature, comparison with accumulated data relating to past room temperature, outside air temperature, and set temperature, “recommended setting of room temperature”. The present invention relates to control for obtaining a “temperature”, allowing the user to set an optimum temperature, and enhancing the energy saving effect.

The determination of the set temperature of the room temperature related to the temperature control of the conventional air conditioner is based on the user's “experience temperature” and “past experience / feel”, and selection of an appropriate set temperature for the air temperature that changes with time or time It was difficult.
For this reason, the room is often inadvertently heated too much (during heating) or too cold (during cooling), and due to this, it has been necessary to change the set temperature several times. In addition, since it is not possible to select an appropriate set temperature according to the air temperature, the energy saving operation cannot be easily performed.
In addition, most recent models automatically select the type of driving and set temperature and start driving, but these cannot cover variations in individual temperature differences.

Also, for example, a control device for an air conditioner as shown in FIG. 6 is known in order to detect the state of the indoor and outdoor environment and the state of the human body and perform air conditioning so as to satisfy human comfort. (For example, refer to Patent Document 1).
In FIG. 6, 1a is an outdoor temperature sensor, 1b is a suction temperature sensor, 1c is a human body temperature sensor, 2a is an outdoor temperature output by the outdoor temperature sensor 1a, 2b is a suction temperature output by the suction temperature sensor 1b, 2c is This is the human body temperature output by the human body temperature sensor 1c.
The human body temperature sensor 1c can be realized by, for example, a pyroelectric infrared sensor that detects infrared rays emitted from the human body. Reference numeral 6a denotes an air volume setting unit on the remote control or the operation panel 6, and 6b denotes a temperature setting unit. Reference numerals 7a and 7b denote a set air volume and a set temperature respectively input by the user through the remote controller or the operation panel 6. Reference numeral 11 denotes a comfort level estimated value PMV (predicted average vote number PredictedMean Vote).

  The operation of the above configuration will be described. Sensor signals 2a, 2b, and 2c from the plurality of sensors in the sensor means 1 provided in the air conditioner 14, that is, the outdoor temperature sensor 1a, the suction temperature sensor 1b, and the human body temperature sensor 1c, are respectively a neural network schematic means (estimating means). ) And is input to the storage means 4 as the sensor signal 3 and stored as a history for the past N seconds (N is a positive real number). The history is output from the storage means 4 to the neural network model means 10. For example, the slope 5 of the suction temperature at intervals of N seconds gives the load of air conditioning from the temporal change rate of the room temperature. From the operation panel 6, the set air volume 7 a and the set temperature 7 b and the position signal 9 from the position sensor 8 of the left and right deflection blades are output to the neural network model means 10.

As described above, the sensor means for detecting the state of the indoor and outdoor environment and the state of the human body, the storage means for storing the history of the state detected by the sensor means, and the setting means for setting the temperature, the air volume, etc. by the user And a position detection means for detecting the position of the left and right deflection blades for deflecting the wind direction, and a comfortable feeling (PMV) of a person in the room based on the outputs of the sensor means, the storage means, the setting means, and the position detection means ) And a control signal generating means for generating a control signal for controlling the air conditioner in response to the estimated comfort, considering the indoor environment and the human condition. Air conditioning is performed to satisfy human comfort and a comfortable living environment can be realized.
However, in the case of the above configuration, the configuration of the control circuit is complicated, the setting means of the user is complicated, and it seems difficult to select an appropriate set temperature corresponding to the temperature. Therefore, there has been a demand for a method in which the control circuit is simple and the user can easily set the optimum room temperature (recommended set temperature).
