Abstract

PURPOSE:To achieve a comfortable air conditioning by controlling the rotational frequency of a blower with a power spectrum adversely proportional to the frequency at a time interval determined by a signal adversely proportional to the frequency. CONSTITUTION:A manually setting circuit 12 for generating constant signal without time variation and a signal generation circuit 9 are connected to a control circuit 11 of a blower 3 through a changeover switch 8. A time L1 for switching to the position of the manually setting circuit 12 is determined with a timer circuit 7 receiving a signal from a signal generation circuit 10. The signal generation circuits 9 and 10 generate an output signal whose frequency varies with the time making the power spectrum adversely proportional to the frequency. Thus, the rotational frequency of the blower 3 is controlled with the power spectrum adversely proportional to the frequency at an interval of a varying time L1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner, and an object of the present invention is to improve comfort during air conditioning.

A conventional air conditioner is a type of air conditioner that air conditions a space by constantly operating physical quantities related to air conditioning (for example, Suita Fukui), as shown in FIG. 6(A).

As a result, the flow rate remains constant and uniform for a long period of time, causing residents to lose their sense of freshness and feel heavy and uncomfortable.
), there is a method that varies a physical quantity (for example, Suita wind it) at a simple constant repetition period, but due to the limited period, it similarly causes discomfort due to a feeling of stagnation.

Therefore, the present invention intermittently controls the physical quantities related to air conditioning in such a manner that the power spectrum of these physical quantities is inversely proportional to the frequency, and also controls the intermittent 11% in such a manner that the power spectrum of the intermittent intervals is inversely proportional to the frequency. It completely eliminates the conventional drawbacks,
Hereinafter, one embodiment of the present invention will be explained based on FIGS. 1 to 5. (11 is the main body of the air conditioner, which has an internal heat exchanger (2), a blower (3), etc., and has a suction rLl (4)
The indoor air sucked in from the room'):J undergoes heat exchange and is blown out from the air outlet (5). (()) is a controller built into the air conditioner body (1), which includes a timer circuit (7),
A switch circuit (8) and a signal generation circuit (+1) that generates a signal with a power spectrum inversely proportional to the frequency 01,
It has a blower control circuit 01) and a hand opening Il setting circuit 02.

In the above-mentioned existing system, when the operation starts, the blower (3) operates at a constant air flow h1c set by the manual setting circuit 02),
The indoor air P1 sucked in from the suction D (4) undergoes heat exchange with the heat exchanger (2), and then becomes the blowout air P1 from the outlet 1 and 5).
2 [section I, 1]. At this time, the timer circuit (7) of the controller (6) is activated, and when a certain period of time set by the signal from the self-generating circuit oQ has elapsed, the switch circuit (8) is activated by the signal from the timer circuit (7).
) switches from the manual setting circuit 02 to the signal generation circuit (Iυ).

The output 1r1 of the signal generation circuit (9) is J,'tl il
l/number changes with time and the power spectrum is inversely proportional to the frequency If as shown in Figure 8. This signal causes the blower (3) to change the power spectrum of the air flow to 1/
The timer circuit (7) is controlled to have a distribution of f [section '-z]+, and the timer circuit (7) is switched li'! When circuit (8) switches to signal generation circuit IIG (9), manual setting circuit 0
2, and when the preset time is reached, the switch circuit (8) starts the timer circuit (7).
), the signal generation circuit (9) switches to the manual setting circuit aS, and a constant signal with no time fluctuation is sent to the blower control circuit (It) so that the set constant wind noise is achieved. Also, at this time, the frequency changes with time from the signal generation circuit O1 to the timer circuit (7), and r, "44
As shown in the figure, a signal whose power spectrum with respect to the set time is inversely proportional to the river wave number is sent, and the constant wind time is set each time, and as shown in Figure 5, the operation in which the sections 1-1 are not the same is repeated. .

Originally, 1// control was a method used to stimulate the skin of the human body with an electric current with a power spectrum of 1/f in order to eliminate pain such as neuralgia. , which corresponds to the discomfort experienced by residents during air conditioning, and it is said that this discomfort can be alleviated by varying the physical quantities related to air conditioning by 1//. but,
If this is attempted to be done in an air conditioner, the signal generation circuit will require short repetitions due to the structure of the signal generation circuit, which is likely to cause the drawback of periodic fluctuations.

Therefore, by controlling the Suita air volume of the blower (3) intermittently by fbit with a power spectrum of 1///, and controlling the intermittent time with a power spectrum of 1/f, the indoor airflow is also blown. +A +31's swaying movement follows the wind and the discomfort to the large bowl is reduced, the freshness and coolness are increased, and the comfort is improved.

The above example concerns the blowing air among the physical quantities related to the sum of air': Ar11Al, but the blowing direction, the temperature of the Suita airflow, and the set temperature in the room! 'us/! ++! temperature, and even surface temperature during radiant heating.
A similar effect can be obtained by controlling the power spectrum at intermittent time intervals to 1///.

As described above, the air conditioner of the present invention intermittently controls the power spectrum of physical components related to air conditioning in a relationship inversely proportional to the frequency, and also controls the power spectrum of intermittent time intervals in a relationship inversely proportional to the frequency. Therefore, when the above physical quantities are kept constant for a long time or changed periodically, the feeling of freshness is lost and the unpleasant feeling of increasing heaviness is not experienced, and the user always receives a feeling of freshness and coolness. is something that improves comfort.
