DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control for providing a comfortable and comfortable environment for a cooling and heating device used in a home or office.

[0002]

2. Description of the Related Art FIG. 29 shows, for example, Japanese Patent Application No. 63-3135.
FIG. 3 is a circuit configuration diagram of a conventional air conditioner shown in No. 65;
0 is a flowchart showing the operation of FIG. 29. FIG.
Shows a control characteristic diagram thereof. In the figure,
Reference numeral 5 denotes an operation switch, 6 denotes a temperature detector made of a thermistor or the like, for detecting room temperature, 7
Is an A / D converter, 8 is a microcomputer as a cooling / heating capacity calculating means having a cooling / heating capacity setting / change means, and has an input circuit 9, a CPU 10, a memory 11, and an output circuit 12. The input circuit 9 includes a temperature detector 6
Is input via the A / D converter 7. The rotation speed of the compressor 13 is changed by the output from the output circuit 12, and the cooling and heating capacity is controlled.

[0003] The operation of the above embodiment, the cooling operation,
This will be described with reference to FIGS. FIG. 30 is a flowchart including the cooling / heating capacity calculating means stored in the microcomputer 8. First, when the operation switch 5 is turned on, the flowchart shown in FIG. 30 starts.
In step S1, a set temperature is set. In step S2, the room temperature detected by the temperature detector 6 is input, and in step S3, a temperature difference (ΔT) between the set temperature and the room temperature is calculated. In step S4, the room temperature is higher than the set temperature and step S5 is performed.
If the operation mode is the normal mode, or if the temperature difference (ΔT) between the set temperature and the room temperature is, for example, 1 deg or more, the cooling / heating capacity is calculated in step S11, and the compressor 13 is operated in step S12. If the room temperature is lower than the set temperature in step S4, the process proceeds to step S10,
The compressor 7 is turned off and the cooling operation is stopped.

When the operation mode is changed to the change mode, it is determined in step S5 that the switch of the change mode is turned on. When the absolute value of the temperature difference (ΔT) between the set temperature and the room temperature is, for example, 1 deg or less, the change mode is entered. In step S6, the current cooling / heating capacity is set as a reference capacity, and for example, 10%
A cooling operation is performed with the increased capacity, and a predetermined time is waited in step S7. After a lapse of a certain time, the cooling / heating capacity is reduced by, for example, 10% from the reference capacity in step S8, and the cooling operation is performed. If the absolute value of the difference between the room temperature and the set temperature is larger than, for example, 1 deg and the room temperature is not near the set temperature in step S5, step S11 is performed.
And enters the room temperature control in the normal mode. Thus, the change mode is set only when the room temperature is near the set temperature, and the room temperature is controlled to change near the set temperature.

FIG. 31 is a control characteristic diagram when the cooling operation is performed based on this embodiment. The horizontal axis is time, and the vertical axis is temperature and cooling capacity. When the operation mode is set to the normal mode and the operation of the air conditioner is started at time T1, the room temperature decreases toward the set temperature indicated by the broken line. Since the cooling capacity is determined from the difference between the set temperature and the room temperature, the cooling capacity decreases as the room temperature decreases. At time T2, the difference between the room temperature and the set temperature becomes small, and the room temperature stabilizes together with the cooling capacity. Time T
When the change mode is set to 3, the cooling capacity changes every fixed time (t) as shown in the figure, so that the room temperature changes periodically near the set temperature.

[0006] This change in room temperature stimulates a temperature receptor in the skin of the user, and the function of regulating the body temperature of the person works. The function of the body temperature regulation function can be considered to activate the physiological function of the user and the activity level of the cerebrum. The room temperature change range (d) is selected by selecting the change range of the cooling / heating capacity generating device so that the user does not become uncomfortable, so that the room temperature does not become uncomfortable and the room temperature is controlled to be constant. A more comfortable and comfortable healthy environment compared to the mode.

[0007]

In this conventional air conditioner, the air conditioner is controlled so that the room temperature changes within a certain range near a set temperature, thereby activating human physiological functions and cerebral activities, thereby providing a comfortable air conditioner. The aim is to get a comfortable environment. A person's sense of heat, such as hot or cold, is determined by the balance between the amount of heat released from the human body and the amount of heat produced. When the amount of heat radiation and the amount of heat production are equal, it is generally said that the user is comfortable. However, we may feel a high degree of comfort when the amount of heat radiation and the amount of heat generated are unbalanced, such as when entering a cool room from a hot outdoors. Also, time gradually elapses,
When the amount of heat radiation and the amount of heat production are equal, the user does not feel comfortable or uncomfortable. Thus, a person feels comfortable when changing from an unpleasant environment to a comfortable environment. A comfortable environment is a changing environment, and it can be considered that the comfort of a person is determined by the level of the environment and the speed of change of the environment. However, in the air conditioner as described above, even if the air conditioning capacity is changed and the room temperature is changed,
Since the room temperature change speed is determined by the cooling / heating load of the room, there has been a problem that the occupant may feel an unpleasant change in the thermal sensation. In addition to the room temperature, there is a problem that the user may feel an unpleasant change in the thermal sensation due to the influence of the distribution of the room temperature, the floor temperature in contact with a person, the radiation temperature of the room, and the like.

The fuzzy rule diagram is for inferring thermal sensation from the fuzzified membership function. The membership function usually indicates a degree of fitness and is a numerical value from 1 to 0. The fuzzy rule is that if there is no change in room temperature (the membership function of room temperature change "None" = 1), the room temperature is "high", "warm" and room temperature is "normal", "neither""When the room temperature is" low, "it is inferred that it is" cool. " The thermal sensation is affected not only by the absolute value of the room temperature but also by the change in the room temperature at that time.
