The calendar / clock unit 32 outputs data relating to the date and time such as the current year / month / day / day of the week. The human body sensor 33 captures infrared light emitted from the human body and converts the presence or absence of a human body in the air-conditioned room and the amount of activity (= whether awake or sleeping) into a voltage magnitude and change, and outputs the voltage magnitude and change.

Of these, as shown in FIG. 2, the indoor control unit 30 includes a main control unit 60, a calculation unit 61, a determination unit 62, and the presence / absence of the room.
It has an absence detector 63 and an extractor 64. Arithmetic unit 6
1 performs a probability distribution calculation by counting the frequency distribution for the output value (voltage level) of the human body sensor 33, and thereby predicts the output value of the human body sensor 33 from the present onward. The prediction method of the calculation unit 61 is not limited to the probability distribution calculation, but any method such as neural network, GA, or linear estimation model may be used.

The judging section 62 judges the occupancy time zone and absence time zone of the resident in the future by comparing the predicted value of the calculation section 61 with a predetermined threshold value. The determination result is sequentially updated and stored in the memory in the main control unit 60 as prediction data.

The room presence / absence detection unit 63 detects in real time whether the resident is in the room or is absent by comparing the output value of the human body sensor 33 with the set value. The extraction unit 64 uses the optical sensor 34 based on the detection result of the presence / absence detection unit 63 and the data of the calendar / clock unit.
And the weather data (output of the weather sensor 42) sent from the outdoor unit B are extracted as necessary.

For example, when the occupancy / non-occupancy detection unit 63 detects the current occupancy, the resident determines whether the output of the optical sensor 34, that is, whether the light is on or off. Based on the determination that it is necessary for operation control in the main control unit 60 as a determination element for whether or not the person is sleeping,
Extract. When the occupancy / absence detection unit 63 detects the absence at the present time, the output of the optical sensor 34, that is, the determination element as to whether the resident is awake or sleeping is not necessary for the operation control in the main control unit 60. Yes, so the output of the optical sensor 34 is not extracted. Further, once a day based on the data of the calendar / clock unit, the weather data is extracted as being necessary for operation control by the main control unit 60. These extracted data are input to the main control unit 60.

The indoor control unit 30 (main control unit 60) and the outdoor control unit 40 mainly include the following functional means. [1] Maintain the four-way valve 2 in the neutral state, and press the compressor 1
The means for carrying out the cooling operation by passing the discharged refrigerant of (4) to the compressor 1 through the four-way valve 2, the outdoor heat exchanger 3, the expansion valve 4, the indoor heat exchanger 5, and the four-way valve 2.

[2] By switching the four-way valve 2, the refrigerant discharged from the compressor 1 is passed through the four-way valve 2, the indoor heat exchanger 5, the expansion valve 4, the outdoor heat exchanger 3 and the four-way valve 2 to the compressor 1. A means of returning and performing heating operation.

[3] Heat exchanger temperature sensor 4 during heating operation
When the detected temperature of 1 becomes 0 ° C. or less, the four-way valve 2 is returned to the neutral state and the flow of the refrigerant is reversed to allow the refrigerant discharged from the compressor 1 (high temperature refrigerant) to flow to the outdoor heat exchanger 3 and thereby the outdoor heat. Means for executing the defrosting operation on the exchanger 3.

[4] During operation, the difference ΔT between the temperature Ta detected by the indoor temperature sensor 31 and the target set temperature Ts predetermined by the remote controller 60 is obtained as an air conditioning load, and the compressor is adjusted so that the air conditioning load ΔT becomes zero. Means for controlling the operating frequency 1 (output frequency of the inverter circuit 44) F. That is, the driving ability is controlled so that the indoor temperature Ta becomes the target set temperature Ts.

[5] A means for starting the driving before the predetermined time when the human body sensor 33 detects the absence of the human body at the present time and when the prediction data includes the entry data of the human body at the predetermined time.

[6] When the operation is started before the predetermined time, the target set temperature is first set to the predetermined value Ts ₁ (= Ts-α or Ts-β) on the lower load side than the original value Ts,
A means for gradually shifting and setting it toward the original value Ts over time.

[7] When the target temperature setting is set to a lower load side than the original value Ts, when the human body sensor 33 detects the entry of the human body at the present time, the target setting temperature is immediately set to the original value Ts. Means to do.

Next, the operation of the above configuration will be described. Depending on whether the resident is in the air-conditioned room or not,
The output value (voltage level) y of the human body sensor 33 is different. Further, even when the resident is in the room, the output value y of the human body sensor 33 changes many times when the resident is awake and the movement of the resident is small when the resident is sleeping. Therefore, the number of changes of the output value y of the human body sensor 33 decreases.

This output value y is input to the arithmetic unit 61 together with the data of the calendar / clock unit 32. In the calculation unit 61, for the output value y of the human body sensor 33, a large number of divided areas having a predetermined width are defined in advance. And
As shown in FIG. 4, the output value y of the human body sensor 33 at the sampling time (the period from a certain time to a certain time) based on the time data of the calendar / clock unit 32.
It is monitored which of the divided areas the initial value of corresponds to, and the occurrence frequency P is incremented by "1" in the corresponding divided area. This is repeated every sampling time, and the probability distribution data for one day is obtained. The probability distribution data for one day is sequentially stored every day from Sunday to Saturday based on the data of the calendar / clock unit 32 while being updated.

Thus, as shown in FIG. 5, a function plane of the probability density function P (t, y) having the time t and the output value y as independent variables is formed for each day of the week. Here, the human body sensor 3
For the output value y of 3, if the value required to determine whether the person is in the room or not is defined as y _th or more (y ≧ y _th ), the probability P _th that an output value y of the threshold value y _th or more is obtained (T) is obtained from the above probability density function P (t, y) by the following mathematical formula 1.

[0043]

[Equation 1]

This probability P _th (t) is shown in FIG.
There are seven days from Sunday to Saturday. These probabilities P _th (t) are input to the determination unit 62. Judgment unit 62
In, for the probability P _th (t), the threshold value Po in order to distinguish the occupancy time zone and the absence time zone has been determined in advance, the probability P _th (t) is equal to or greater than a threshold value Po It is determined that the period is the occupied time period and the other period is the absent time period. That is, in the data of FIG. 6, it is determined that the period from time t _{1 to} t _{2 and} the period from time t _{3 to} t ₄ are the occupied time periods, and the other periods are determined to be the absent time period.

The determination result of the determination unit 62 is stored in the memory of the main control unit 60 while being sequentially updated as prediction data of future human body activity. Residents' activities have a specific pattern based on a week from Sunday to Saturday.Proceeding with prediction while learning that pattern repeatedly, does not require any operation of the resident and is unconscious for the resident. In addition, fully automatic air conditioning is possible.

From here, an example of what operation is performed based on the predicted data will be described with reference to Table 1 and FIG. Table 1 shows how to set the next operation mode when the human body detection status changes in the current operation status (including the target set temperature) according to the predicted occupancy time zone and absence time zone. It is a summary of what to do.

[0047]

[Table 1]

It is assumed that the room / absence detection unit 63 detects the absence of the human body at the present time. And the indoor control unit 3
At 0, it is assumed that it is predicted that the occupancy time zone will start from time t ₁₃ earlier than the present time.

In this case, the predetermined time at time t ₁₃ (= Δtx
+ Δts) before, a predetermined value Ts ₁ (= Ts−) on the low load side from the original value Ts determined by the remote controller 50.
α) is commanded as the target set temperature, and the heating operation is started [(4) in Table 1]. A predetermined time Δt from the start of this operation
During x, Ts ₁ is held as the target set temperature [(7) in Table 1]. When the predetermined time Δtx elapses (time t ₁₃
Δts time before), the target set temperature is shifted and set to the original value Ts [(6) in Table 1]. Thereafter, the target set temperature Ts is reached until the time t ₁₃ and also after the time t _13.
The setting is continued [(3) in Table 1].

In this way, the time t _{13 when the} time in the room starts begins
By starting the heating operation before that, the room is already warm and comfortable when the resident enters the room. Moreover, since the target set temperature is set to Ts ₁ on the lower load side than the original value Ts for a while after the start of the operation, the power consumption can be suppressed as much as possible and the energy saving operation can be achieved.

After that, the operation is stopped at the end of the time in the room. Residents' activities are easily affected by the weather. For this reason, even if it is the time when the occupied time period ends and the absent time period begins in the forecast data, it is judged that there is a high possibility of being in the room on a holiday and in the case of rain. Is continued.

However, it is assumed that the room / absence detecting unit 63 detects the absence of the human body at the present time when the operation is continued (time t ₁₄ ). In this case, the operation is continued for the predetermined time Δty _{1 with the} original target set temperature Ts [(10) in Table 1]. Then, after the lapse of the predetermined time Δty _1, it is confirmed whether or not the room / absence detection unit 63 still detects the absence of the human body at the present time.

If the absence of the human body is still detected, a predetermined value Ts ₁ (= Ts-β) on the lower load side than the original value Ts is commanded as the target set temperature [(11) in Table 1], and Are retained [(1) in Table 1].

When the predetermined time Δty ₂ has passed, if the next occupied time zone based on the prediction data is still sufficiently ahead,
When it is judged that it is not necessary to continue the operation, the operation is immediately stopped [(1) in Table 1].

This is because when the resident leaves the room, the situation is immediately judged to be absent, and if the driving is immediately stopped, the driving is stopped when the person leaves the room for a short time due to a toilet or the like, and immediately enters the room. It is intended to prevent discomfort by reducing the set temperature after the resident leaves the room and continue the operation while suppressing power consumption, and make sure to stop the operation if the absence is confirmed enough. Is what you are doing.

By the way, there are cases where a resident enters the room during the absence period based on the prediction data. For example, it is assumed that the resident's entry is detected at time t ₁₁ before time t _{13 when} the room time zone starts. In this case, the original value Ts is commanded as the target set temperature, and the operation is immediately started.

Further, a predetermined time of time t ₁₃ (= Δt x + Δ
ts) before and when the operation with Ts ₁ as the target set temperature has already started (for example, time t ₁₂ ),
It is assumed that entry is detected there. In this case, the target set temperature is immediately switched to the original value Ts [(2) in Table 1].

By switching the target set temperature, the room quickly shifts to a comfortable state. Then, with respect to such deviation of the prediction data, the degree of deviation is stored, and the predetermined time (= Δtx + Δts) before the time t ₁₃ is changed based on the deviation data.

For example, as shown in FIG. 8, this is performed by monitoring the resident's entry into the room from a predetermined time Δtn before the time t ₂₂ predicted to be entered.

That is, the Δtn time is divided into several (10 in FIG. 8) sections in a certain time unit, and the counter array m (i) [i is 1, 2, ... 1 is associated with these sections.
0] is prepared.

At time t ₂₁ during Δt n time,
When the absence detection unit 63 detects that the resident has entered the room (when it has been removed), the count value N _{m (2) of} the counter array m (2) corresponding to time t ₂₁ is incremented by “1”.

N _{m (2)} = N _{m (2)} +1 In addition to the counter array m (i), the total number counter M is prepared. When the counter array m (i) is incremented, the total number counter M is counted at the same time. The value N _M is incremented by "1".

N _M = N _M +1 By repeating the above, the distribution P of the outlier probability is formed as shown in FIG.

P = N _{m (i)} / N _{M Using} this distribution P, the time between the actual entry time t ₂₁ and the expected entry time t ₂₂ , that is, the deviation time Δtsx, is set to a specific threshold value. For Pth,

[0065]

[Equation 2]

It is determined that This deviation time Δ
Thereafter, tsx is used as it is as a predetermined time (= Δtx + Δts) before time t ₁₃ in the example of FIG. That is, the operation start timing before time t ₁₃ is adjusted. It should be noted that the update of the out-of-range time Δtsx is carried out periodically based on the data of the calendar / clock unit 32, for example, once a month.

By the way, when the occupancy / absence detection unit 63 detects the occupancy at the present time, the output of the optical sensor 34, that is, whether the light is on or off, whether the resident is awake or sleeping It is extracted by the extraction unit 64 as a discriminant element of whether or not it is included in the operation control. For example,
When the resident is sleeping, the driving frequency F can be lowered because low capacity driving is sufficient. This leads to energy saving operation.

When the room / absence detection unit 63 detects the absence at the present time, the output of the optical sensor 34 is the extraction unit 6
It is not extracted in 4 and is not used for operation control. Therefore, an unnecessary load is not applied to the control function of the main control unit 60,
Control can be speeded up and reliability can be improved.

In the above embodiment, only Ts ₁ is used as the target set temperature on the low load side, but two or more values may be used and gradually set.

In the above-mentioned embodiment, the output of the optical sensor 34 is used as a discriminating element for whether the resident is awake or sleeping. However, the amount of activity whether the resident is awake or sleeping is determined by the arithmetic unit 61. It is also possible to predict the activity amount whether the resident is awake or sleeping by preparing some threshold values different from the value y _th and using them to further calculate the probability distribution.

[0071]

An environment sensor for detecting the output of the human body sensor, and an extraction means for extracting the output of the environment sensor when necessary based on the output of the human body sensor, the output of the human body sensor, the output of the date / time data output means, and the output of the extraction means for the future human body. Since it is equipped with a predicting means for predicting the activity of the human body, it is possible to accurately predict the activity of the human body in the future.
