Abstract

PURPOSE:To obtain an air-conditioning machine, capable of detecting the temperature condition of a floor surface with a good accuracy through an inexpensive means and forming comfortable indoor atmosphere in accordance with the temperature condition of the floor surface. CONSTITUTION:A radiation sensor, detecting infrared rays from a floor surface, is provided near an air outlet port 5 as a floor surface temperature detector 7 while the value of temperature rise per unit time is obtained from the floor surface temperature detected by the floor surface temperature detector 7. The value of temperature rise is compared with a preset threshold value and when the value of temperature rise is larger than the threshold value, it is decided that the rise-up of floor surface temperature is started and an airflow plate control means 9 controls an airflow direction plate driving motor 10 to set the direction of the airflow direction plate 6 so that warm-air, sent out of the air outlet port 5, is conducted toward the center of the floor surface. On the other hand, when the value of temperature rise is higher than the threshold value, it is decided that the floor surface temperature is in a stationary condition whereby the direction of the airflow direction plate 6 is set so that the warm-air, sent out of the air outlet port 5, is divided into a part which flows in parallel to the surface of a ceiling and the other part which flows downward in parallel to wall surfaces.

In the prior art based on the wind direction control system shown in FIG. 8, the temperature of the floor surface becomes high and the temperature is made uniform, and it is effective when the floor surface temperature rises. . However, since the warm air 103 having a high wind speed is sent to the feet, the user feels a considerable air flow,
This air flow lowers the sensible temperature. Further, in an air conditioner with variable capacity, the temperature of the warm air is as low as around 30 ° C., which may make the user feel chilly and may not be comfortable.

In order to improve the temperature distribution in the room,
In the system that controls the wind direction plate as described above,
If you do not understand the situation in the room, there is a risk that the floor temperature will not rise and warm air will accumulate in a certain place. Therefore, in order to grasp the situation in the room, a method is conceivable in which the room temperature detector detects the room temperature and the floor surface temperature detector detects the floor surface temperature to control the position of the wind direction plate. However, looking at the accuracy of the radiation sensor generally used as the floor surface temperature detector, there is a variation of ± 5.0 ° C. or more even with a single unit. An example of a case where this is stored in the decorative cover of the indoor unit due to its design is shown in FIGS. 9 to 11. However, in the figure, 17 is a makeup cover, 18 is a radiation sensor, and 19 is an infrared ray.

Therefore, in FIG. 4, the wind direction plate control means 9 first compares the room temperature detected by the room temperature detector 8 (FIG. 1) with a predetermined set temperature (step S).
1). Then, as a result of this comparison, when the room temperature is lower than the set temperature, it is determined that the room temperature has not reached the temperature desired by the user and the temperature is still rising, and the warm air is blown to the center of the floor. The wind direction plates 6a and 6b are brought into the state shown in FIG. 3 (a) (step S6). When the room temperature is equal to or higher than the set temperature, it is determined that the room temperature has reached the temperature desired by the user and has already risen, and the floor surface temperature detector 7 (FIG. 1) detects the floor surface temperature. Then (step S2), the floor surface temperature deviation value ΔTf per unit time is calculated as described above (step S3). Then, the floor surface temperature deviation value ΔTf and the floor surface temperature deviation threshold value Δ stored in the floor surface temperature information storage unit 12 (FIG. 2) in advance.
The size of Tset is compared and discriminated (step S4), and the floor surface temperature deviation value ΔTf per unit time is calculated as the floor surface temperature deviation threshold value ΔT.
When it is smaller than set, it is determined that the temperature gradient per unit time is small and the floor surface temperature is stable, that is, the floor surface temperature is saturated, and the wind direction plates 6a and 6b are set to the state shown in FIG. Warm air that flows parallel to the ceiling surface and warm air that flows downward and parallel to the wall surface are blown out from the air outlet 5 (FIG. 1) (step S5). Further, the floor surface temperature deviation ΔTf per unit time is the floor surface temperature deviation threshold ΔTset.
Room temperature has reached the desired temperature when
It is determined that the floor surface temperature is still rising (while rising), and the wind direction plates 6a and 6b are set to the state shown in FIG. 3 (a) so that warm air flows toward the center of the floor surface. (Step S6).

As described above, by repeating the series of processing operations of steps S1 to S6 of FIG. 4, when the floor surface temperature is low at the time of rising, as shown in FIG.
4 is sent toward the center of the floor surface, and the living space warms up quickly and efficiently. Also, in the steady state when the floor surface temperature is saturated, as shown in FIG. The warm air 15 flowing along the wall surface and the warm air 16 flowing downward along the wall surface are blown out so that the temperature of the living space is not lowered and the human body is not exposed to the warm air. Therefore, the rise of the floor surface temperature is fast, and in a steady state, a comfortable heating space that does not feel the wind is formed.

When the wind direction plate 6 is brought into the state shown in FIG. 3 (a), as shown in FIG. 6 (a), the warm air blown out from the indoor unit is 100% toward the center of the floor surface. When the wind direction plate 6 is in the state shown in FIG. 3B, the warm air flowing parallel to the ceiling surface and the warm air flowing parallel to the wall surface and downward are generated at a predetermined ratio. However, here, in the above-described embodiment, when the wind direction plate 6 is stationary,
In the state shown in (b), and as shown in FIG. 6 (b), the air flow ratio of the warm air flow 15 along the ceiling surface to the warm air flow 16 along the lower part of the wall surface is 30:70. Then, the horizontal temperature distribution of 5 cm above the floor in the living space at this time is shown in FIG.
It becomes like (b). On the other hand, as in the conventional method, even in the steady state, as shown in FIG.
When 0% warm air is blown toward the center of the floor, the horizontal temperature distribution of 5 cm above the floor in the living space is shown in FIG.
It becomes like (a). Comparing these horizontal temperature distributions, as compared with the case of the conventional method shown in FIG.
In the case of the above-mentioned embodiment shown in (b), it can be seen that the high temperature zone spreads in the living space. Also, regarding the wind speed at the feet, for example, between 8 tatami mats, the height in the center of the room is 5 cm above the floor, and the conventional method is 0.6 m / sec.
In the above example, it was weak at 0.3 m / sec and 30 cm above the floor.
In the conventional method, it was 0.8 m / sec, but in the above-mentioned embodiment, it was as weak as 0.3 m / sec.

As described above, according to the present invention,
Even if the measurement accuracy of the floor temperature is low due to the variation in the detection accuracy of the floor temperature detector, the floor temperature can be calculated by using the difference between the detection results and the floor temperature deviation value per unit time. Therefore, the floor surface temperature deviation value can be obtained with high accuracy, and therefore the floor surface temperature situation can be accurately determined. This makes it possible to accurately set the indoor temperature environment.
