Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation control device for an air conditioner, and more particularly to a control device adapted to a thermal sensation of a resident.

[0002]

2. Description of the Related Art As an operation control device of an air conditioner of this type, there is a prior application using an individual difference learning adaptive control (US application No. 799086, US application date November 27, 1991).
Day). This operation control device calculates a thermal sensation index of predicted thermal sensation, which is a function of indoor environmental physical quantities such as indoor temperature, and a plurality of parameters, while the occupant declares true thermal sensation. , Learn the above parameters, calculate the thermal sensation index from this parameter and the indoor temperature, etc., and control the frequency of the compressor based on this thermal sensation index so that the comfort of the occupants can be satisfied. It was done.

In the operation control device of the air conditioner described above, one input and one output, that is, the frequency of the compressor is used as the control input, and the thermal sensation index is used as the output. When calculating the index, if the airflow velocity is changed, the thermal sensation index does not become linear. Therefore, the airflow velocity is calculated to be constant. As a result, the operation control device has a problem that the occupant's comfort cannot be satisfied by the thermal sensation index when the air velocity for the occupant changes when the occupant moves. . Further, conventionally, since the parameter initial value of the thermal sensation index is set to only one average value, there is a problem that the convergence of parameters is poor.
In other words, the environmental condition of the resident is not always constant, the amount of clothing differs between summer and winter, and the thermal sensation felt by the resident varies depending on the amount of activity such as sitting and standing, so the initial parameter values are If it is constant, it takes time to match the thermal sensation index to the occupant's true thermal sensation, and there is a problem that comfort is impaired. Further, since the frequency of the compressor is PID-controlled based on the thermal sensation index, the thermal sensation index overshoots and it takes time for the thermal sensation index to converge, resulting in a longer control time and comfort. There was a problem that the sex was impaired.

The present invention has been made in view of the above point, and it is possible to satisfy the occupant's comfort by making it possible to cope with the change of the air velocity and improve the convergence of the thermal sensation index. It was made to let.

Therefore, the outline of the individual difference learning adaptive control in the adaptive control system (4) which is the basic principle of the air conditioning control will be described. First, in order to apply the expected average declared PMV to this control, some of the formulas adopted by Fanger are replaced with the relations shown in the following formula. The formula for radiant heat transfer is R = hr ・ (Tc1-Tr) …… (1) R: Heat radiation per unit area hr: Radiant heat transfer coefficient Tc1: Clothing temperature Tr: Radiant temperature, 18.0 ℃ <Tr <30.0 ℃ Become. The equation for convection heat transfer is hc = hcn + hcf = constant + κ · V ^0.67 (2) hc: convection heat transfer coefficient hcn: forced convection heat transfer coefficient hcf: natural convection heat transfer coefficient κ: constant V: airflow velocity and Become. From the above equations (1) and (2), the following equation in which the thermal sensation index Vhat is developed in an explicit form is derived.

As a result, when the user (12) moves, etc., the comfort of the user (12) can be maintained even if the airflow velocity received by the user (12) changes, so that the user (12) can cover a wide range. You can improve your comfort. Further, since the air conditioner (2) is fuzzy controlled, overshoot of the thermal sensation index can be prevented as compared with the conventional PID control, so that the thermal sensation index can be quickly converged. Can be made. That is, as shown in FIG. 10, the thermal sensation index Vhat converges without overshooting. On the other hand, conventionally, as shown in FIG.
In the D controller, overshooting occurred as at point X, and the convergence of the thermal sensation index Vhat was poor. As a result of being able to improve the convergence of the thermal sensation index Vhat,
Since the control time can be shortened, the comfort of the user (12) can be quickly satisfied. Moreover, since the parameter initial value is set to a different value based on the clothing amount and the activity amount of the user (12), the parameter C
It is possible to accelerate the convergence of hat0 to Chat3. That is, conventionally, for example, the clothing amount Icl is 0.6 and the activity amount is 51.7.
While it was fixed at 5Kcal / hr m ² , the parameter Cha
Since the initial values of t0 to Chat3 can be set in the vicinity of the optimum value, the control time can be shortened and the occupant's comfort can be quickly satisfied.

Although the fuzzy controller (51) is used in the present embodiment, the thermal sensation index Vhat which is an input signal is used.
A neuro control for controlling the compressor by weighting etc. may be used. The report input section (61) is not limited to the remote controller and may be a dedicated input means. The adaptive control system (4) is not limited to the embodiment, and the air conditioner (2) is not limited to the wall hanging type. When calculating the parameters θhat0 to θhat6,
It may be performed based on three or more airflow velocities.
Further, according to the present invention, only the parameters θhat0 to θhat6 may be set based on a plurality of airflow velocities, only fuzzy control may be performed, and the parameter Chat0 may be set.
It is needless to say that only ~ Chat3 may be changed or a combination thereof may be used.
