[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a detecting means capable of detecting a human or an environmental condition, and detects a degree of comfort of a person present in a room from various information obtained thereby. The present invention relates to a control device for an air conditioner that performs control based on the control of the air conditioner to improve the comfort and operability of a room person.

[0002]

2. Description of the Related Art A conventional control device for an air conditioner of this type will be described. In recent years, PMVs (ISO) that take into account not only the temperature index but also factors related to comfort other than temperature are considered.
7730-1984). As a first field, for example, a configuration described in an embodiment of JP-A-4-84055 is known. The configuration will be described below. Air temperature,
Measure radiation temperature, humidity, and airflow as ambient environment side elements,
In addition, the amount of human movement and the amount of clothes are estimated as human factors,
Whether to perform control based on the human element and the environment element,
The PMV, which is a comfort index, is calculated from these factors using a PMV calculation formula, and control is performed based on the PMV.

As a second field, for example, a configuration described in an embodiment of Japanese Patent Application Laid-Open No. 4-268146 is known. The configuration will be described below. PMV is calculated based on six factors: temperature, humidity, airflow, radiation temperature, amount of activity, and amount of clothes. By setting appropriate values in advance only for the four elements of airflow, humidity, activity amount, and clothing amount,
The relationship between temperature and radiation temperature is approximated by a linear function in the PMV calculation formula. For example, the PMV value is 0, the temperature is TA, and the radiation temperature is T.
Assuming that R, 0 = K1 * TR + K2 * TA + K3 K1: constant K2: constant K3: constant That is, if the above equation is rewritten, TA = − (K1 * TR + K3) / K2, and when the radiation temperature is detected, the target temperature is determined. it can. The air conditioner is controlled based on the target temperature.

[0004]

However, in the above configuration, in the first field, as a method for deriving an input element, all surrounding environment-side elements are measured by sensors for measuring each element. However, there are many factors that are difficult to measure in terms of the measurement method, while increasing the cost when commercializing. In other words, using a radiation sensor or airflow sensor for PMV measurement leads to an increase in cost as a product, and actually arranging a sensor indoors
Have difficulty. Further, there is a problem that even if the detection and estimation of these plural elements can be performed, a complicated calculation is required to calculate the PMV value. In the second field, in this case, the reference for controlling the air conditioner is a target temperature.

Even if there is only one person, the temperature near the person, which has the greatest effect on the comfort level among the six factors, cannot be detected in response to the change in the position of the person, so the PMV value corresponding to the change in the position cannot be detected. Difference cannot be calculated. Therefore, even if there is only one person in the room, the degree of comfort that the person actually feels cannot be accurately calculated, so that there is a problem that it is not possible to perform detailed control corresponding to the person. .

Accordingly, the present invention easily and directly calculates individual comfort levels in consideration of the temperature, radiation temperature, airflow, clothes, humidity, and activity amount near a person, and calculates the temperature, radiation temperature, airflow,

An object of the present invention is to improve the comfort of a person and the operability.

Further, the present invention easily and directly calculates individual comfort levels in consideration of the temperature, radiation temperature, airflow, clothes, humidity, and activity amount near a person, and calculates the temperature, radiation temperature, airflow,
By automatically controlling the blowing shape of the air conditioner in accordance with the comfort, radiation temperature, near-person temperature, operation mode and set comfort in consideration of clothing, humidity, activity amount,
The purpose of the present invention is to further improve the sense of airflow and comfort and improve the operability of a person by achieving the suppression of the feeling of cool radiation on the floor, the further improvement of the reach of warm air, and the suppression of the sense of airflow.

[0038]

[Table 2]

In the near-person temperature calculating section 40, the suction temperature signal 400, which is an output value from the suction temperature detecting means 15, is output.
From the correction amount signal 391 and the correction amount signal 391, the temperature near the person is calculated based on the following equation, and the temperature near the person = the suction temperature + the correction amount. For example, “R1 = 2 (m), R2 = 4 (m), and the human body position is Assuming that the air flow rate is 2.5 m, the air volume is low, the operation mode is heating, and the suction temperature is 18 ° C., the correction amount is −0.5 from the above table.

Next, details of the comfort level calculating means 23 will be described. The comfort level calculating means 23 normalizes the normal PMV calculation formula calculated from the six parameters of temperature, humidity, air current, radiation temperature, activity amount, and clothing amount, thereby obtaining the temperature, that is, the near-person temperature signal 221 and the radiation level. The comfort or PM by the two parameters of the temperature signal 211
V value can be calculated. That is, the PMV value is 0
Reference point, for example, temperature near human: 24 ° C., humidity: 5
0%, air flow: 0.2 m / s, radiation temperature: 24 ° C., activity: 1.0 met, clothing: 1.0 clo From the PMV values obtained by changing the temperature to, for example, 20 ° C., 24 ° C., 28 ° C., and 32 ° C., an approximated PMV calculation formula determined only by the temperature near the human is obtained. For example, PMV (temperature near a person) = 3 * (a * temperature near a person−d) −
3

Similarly, the reference values other than the radiation temperature are fixed, and the radiation temperature is set to, for example, 20 ° C., 24 ° C., 28 ° C., 32 ° C.
An approximated PMV calculation formula determined only by the radiation temperature is obtained from the PMV value obtained by changing the temperature to ° C. If this equation is, for example, PMV (radiation temperature) = 3 * (c * radiation temperature−b) −3, it is standardized, and the simplified PMV can be calculated using two parameters of the near-human temperature signal 221 and the radiation temperature signal 211. The converted PMV calculation formula is represented by the following formula.

PMV (near person temperature signal 221, radiation temperature signal 211) = 3 * (a * near person temperature signal 221-b)
* (C * radiation temperature signal 211-d) -3 The comfort level calculation unit 23 is an output value from the radiation temperature calculation unit 21 and the near-person temperature estimation unit 22 based on the simplified PMV calculation formula. The comfort level of each person present in the room is calculated from the radiant temperature signal 211 and the near-person temperature signal 221 of each person present in the room, and the comfort levels for the persons are calculated as the comfort level signals 231, 232, 233, and 234. Are output to the comfort airflow correction means 24, the comfort clothing flow correction means 25, the comfort humidity correction means 26, and the comfort activity amount correction means 27, respectively.

In the above embodiment, P is calculated by standardization so that the two parameters of temperature and radiation temperature can be calculated.
The MV calculation formula was simplified, but PMV calculation was performed using two parameters of temperature and radiation temperature as in other approximation methods, such as substituting four values excluding temperature and radiation temperature into the PMV calculation formula. Equations are simplified, the temperature near each person and the radiation temperature near each person are detected, and each PMV
