Abstract

PURPOSE:To fluctuate the speed of blow-off air periodically and effect the air conditioning of a room in a good condition by a method wherein a blow-off air speed changing device and a control device, making the power spectrum of the fluctuation of the speed of the blow-off air inversely proportional to a frequency, are provided in an indoor unit. CONSTITUTION:The air conditioner 1 is effecting a necessary air conditioning by a method wherein indoor air, sucked by a fan 3 through a suction port 4, is forced to exchange the heat thereof in a heat exchanger 2, thereafter, is blown out of a blow-off port 5. In this case, a damper 6 is provided at the upstream side of airflow direction control panels 7, which are swingable through a connecting rod 11, as the blow-off air speed changing device. The damper 6 is made so as to be movable in up-and-down by the rotation of a cam 9 attached to the shaft of a step-motor 10 against a push-up spring 12. The rotating angle of the step-motor 10 is controlled through a motor control circuit in accordance with a signal from a generator generating an output having the power spectrum in proportion to 1/f wherein a human body is never considered to feel to be accustomed to stimulation thereto or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner, and the present invention relates to an air conditioner that has a pleasantness level of 1 to 1 during heating and cooling.
Some conventional air-button devices aim to improve the indoor environment by periodically varying the Suita wind speed, but one way to do this is to increase the number of rotations of the blower. There are many. In this case, the Suita wind temperature fluctuates as the Suita wind speed fluctuates, and if the amount of heat input is constant, the Suita wind temperature will fluctuate, and the room temperature will gradually change. In addition to causing discomfort, the wind speed (wind rice) increases during heating.
As the temperature increases, the wind temperature decreases, creating a feeling of cold air. To deal with this, a damper or the like is installed at the air outlet, and the area of the air outlet is controlled by controlling periodic fluctuations in its opening degree to keep the airflow constant, and only the wind speed is periodically changed to eliminate fluctuations in the temperature of the air being blown out. The method has also been refined and the above drawbacks have been resolved. However, this method has the drawback that the indoor air L fluctuates rapidly, causing the indoor air to lose its freshness due to admiration, resulting in discomfort due to a feeling of stagnation. By varying only the Suita wind speed and controlling the power spectrum of the fluctuation in a relationship that is inversely proportional to the frequency (hereinafter referred to as 1/f), the above conventional disadvantages of °C have been overcome. Hereinafter, one embodiment of the present invention will be explained based on FIGS. 11 to 5. (1) is the air conditioner main body [indoor unit],
It has a heat exchanger (211 air blower (3)) etc. inside.Indoor air sucked in from the air inlet (indoor air) is heated through the air outlet (6), or is heated through the air outlet (5). A single time change of the damper (6) provided as a wind direction changing device is controlled by the control device* (8) by changing the power spectrum proportional to 1/f, and as a result, the Suita wind speed also changes by the same amount. The fluctuation of is given. 0υ is the connecting rod of the wind direction control plate, and 0υ is the upward movement of the damper (6).

When air conditioning is started in the above configuration, the step motor OQ that drives the damper installed via the cam (9) to move up and down starts operating, or the rotation angle of this step motor is 1/f. The first motor is controlled by a signal sent to the step motor control circuit 04 from the first damper (1), and the damper (6) changes with a power spectrum proportional to 17f, controlling only the blowing wind speed. The figure shows the time change of the blowing wind speed, and Figure 6 shows the power spectrum.

It is known that fluctuations having a power spectrum of 1/f are closely related to human senses in non-electrical ways, and heartbeat cycles and brain waves at rest have a power spectrum of 1/f.

Also, the power spectrum of the sound power and frequency fluctuation of Shinjuku's sustained and pleasant music is proportional to 1/f. Based on this knowledge, there are some cases in which the intensity and interval of the current applied when relieving pain from dementia, etc., is varied with a 1/f power spectrum, and the effect is obtained. In other words, Friend 1, which has a power spectrum proportional to 1/f, is thought to provide a feeling of security because the human body does not get used to the stimulus, maintains freshness, and matches the rhythm of the senses. It is something that can be done. Therefore, when the mellow air is blown into the room, the opening degree of the damper (6) should be adjusted to 1/f.
By controlling the variation with a power spectrum of °
The C1 blowout was vibrating, and the airflow in the room was so bad! Because it moves with the flow of water, there is no heavy slope caused by getting used to it, and a sense of freshness is maintained in the wealth, providing a very pleasant cooling and heating effect.

In addition, this damper (6) only changes the wind speed, and the wind gate remains constant, so there is no fluctuation in the Suita wind temperature, and the room temperature vibrates and changes from the setting to thicker. During,
When the wind turbine increases in size, there is no possibility that the wind will drop and give a feeling of cold wind.

As is clear from the above description, in the air conditioner of the present invention, the power spectrum of the time vibration of the Suita wind speed is proportional to 1/f, and the Suita Phoenix is kept constant while only the wind speed is varied. The Suita air temperature is constant, there is no unpleasant room temperature fluctuation or feeling of cold air, and there is no sinking due to f stuffiness, so you can always get a great air conditioning effect that keeps you fresh.
