The specific embodiment
Describe the preferred embodiments of the present invention with reference to the accompanying drawings in detail.
Be arranged on the air conditioner of the invention in certain indoor space in order to regulate air, be equipped with in comprising heat exchanger and pressure fan housing, be combined on the above-mentioned housing and suck and discharge room air front panel, attached on the side of above-mentioned front panel and measure at least above-mentioned indoor two positions radiation temperature the radiation temperature detector and calculate indoor comfort degree and control the microcomputer of the discharge rate of above-mentioned air conditioner according to this comfort level according to the indoor radiation temperature that is detected by above-mentioned radiation temperature detector.
Air conditioner of the present invention can be wall-hanging or cabinet type air conditioner especially, and at this moment above-mentioned radiation temperature detector S regulates moving up and down blade 12 or be installed on the shutter board 22 of the move left and right on the front panel 21 of the such cabinet type air conditioner 20 of Fig. 5 on the front panel 11 of machine 10 attached to being installed in the such wall hanging type air of Fig. 4.Therefore, said temperature detector S can move the radiation temperature of measuring above-mentioned a plurality of spaces by the driving along with the louvre blade 22 of above-mentioned blade that moves up and down 12 or move left and right.
Fig. 6 is the figure that is measured indoor temperature when being illustrated in the air conditioner 30 inhabitation room configuration that are attached with the radiation temperature detector on the louvre blade of the blade that moves up and down or move left and right by the radiation temperature detector.That is to say, drive the radiation temperature that the limit is measured a plurality of space a between above-mentioned residential houses, b, c, d, e, f, g pivotally under the mode along with air conditioner on louvre blade limit attached to the radiation temperature detector on the shutter board of the move left and right of above-mentioned air conditioner with above-mentioned move left and right, because the microcomputer of above-mentioned air conditioner is controlled discharge rate according to the radiation temperature of measuring in these a plurality of spaces, so the indoor temperature that air conditioner of the present invention is disposed keeps evenly.
Fig. 7 is the block diagram that expression resembles the formation of the air conditioner of the present invention 30 of measuring a plurality of space radiation temperature above-mentioned.As shown in Figure 7, air conditioner 30 of the present invention comprises: measure the indoor temperature of space specified indoor temperature detector 31, measure the radiation temperature detector 32 of the radiation temperature in a plurality of spaces, microcomputer 33 that the value measured according to above-mentioned indoor temperature detector 31 and radiation temperature detector 32 calculates comfort temperature, make the blade that moves up and down of above-mentioned air conditioner or the shutter board drive electric motor M of move left and right according to the control signal of above-mentioned microcomputer 33.
At this, the microcomputer of above-mentioned air conditioner 33 calculates indoor comfort temperature according to the radiation temperature of measuring in above-mentioned a plurality of spaces, relatively the fiducial temperature set in air conditioner in advance of this temperature that calculates and user and control air conditioner.
Be under the situation of air regulator for example at above-mentioned air conditioner, when the indoor comfort temperature that goes out in aforementioned calculation is lower than the fiducial temperature of above-mentioned setting, the microcomputer 33 of above-mentioned air conditioner reduces the discharge rate of above-mentioned air conditioner, control simultaneously makes the shutter board drive electric motor M of move left and right, is not delivered to the place of measuring low relatively radiation temperature so that discharge wind.
In addition, when the indoor comfort temperature that goes out when aforementioned calculation is higher than the fiducial temperature of above-mentioned setting, the microcomputer 33 of above-mentioned air conditioner increases the discharge rate of above-mentioned air conditioner, control simultaneously makes the shutter board drive electric motor M of move left and right, delivers to the place of measuring high relatively radiation temperature so that discharge hearsay.
At this, above-mentioned microcomputer 33 is to be N in a plurality of space radiation temperature that above-mentioned radiation temperature detector 32 is measured, when radiation temperature (i) is i mensuration radiation temperature, by comfort temperature in the following mathematical expression counting chamber:
[several 1]
Fig. 8 is the figure of the control method of expression air conditioner of the present invention.
At first in the 11st step (S11), regulate radiation temperature detector on the move left and right shutter board of the blade that moves up and down of machine or cabinet type air conditioner attached to wall hanging type air along with the radiation temperature in a plurality of spaces in the driving measuring cell of above-mentioned air conditioner.
In the 12nd step (S12), the microcomputer of above-mentioned air conditioner calculates the indoor comfort temperature that the user feels according to the radiation temperature and the above-mentioned mathematical expression 1 of above-mentioned the 11st step measurements.
In the 13rd step (S13), whether the more above-mentioned indoor comfort temperature of the microcomputer of above-mentioned air conditioner is identical with fiducial temperature in being set in above-mentioned air conditioner.
If above-mentioned indoor comfort temperature is identical with fiducial temperature in above-mentioned the 13rd step, then the control method of air conditioner of the present invention turns back to the 11st step.
In addition, when above-mentioned indoor comfort temperature and fiducial temperature are inequality in above-mentioned the 13rd step, then carry out the 14th step (S14), whether the more indoor comfort temperature of the microcomputer of air conditioner is than fiducial temperature height.
When indoor comfort temperature was higher than fiducial temperature in above-mentioned the 14th step, then in the 15th step (S15), the microcomputer that above-mentioned room air is regulated machine increased the discharge rate of air conditioner.
In addition, lower than fiducial temperature as indoor comfort temperature in above-mentioned the 14th step, then in the 16th step (S16), the microcomputer of above-mentioned air conditioner reduces the discharge rate of air conditioner.
Fig. 9 is the curve that expression utilizes air conditioner of the present invention and control method indoor temperature change generated in case state thereof.
As shown in figure 19, indoor temperature drives the back at air conditioner and descends apace for the temperature that reaches user's setting, rises again behind certain hour.Represent current indoor temperature at this solid line, and the indoor temperature interval that the user can feel comfortably cool is represented in the interval between dotted line.
Because above-mentioned solid line is driving air conditioner after be positioned at above-mentioned dotted line behind the certain hour, so, may often keep best indoor comfort index even the method operating air conditioner machine that the user need not be other also can keep the comfort temperature that do not feel cold.
Controllable air conditioner of of the present invention indoor radiation temperature and method of operating thereof according to above formation, on the shutter board of radiation temperature detector attached to blade that moves up and down that is installed in indoor wall hanging type air adjusting machine or cabinet type air conditioner for the adjusting air or move left and right, utilize the above-mentioned radiation temperature detector radiation temperature of interior 2 positions of measuring cell at least, temperature value according to these mensuration, calculate be not indoor temperature and actual indoor comfort temperature, control the discharge rate of air conditioner etc. according to this indoor comfort temperature that calculates, because according to not being to limit the temperature in the space be arranged on the air conditioner on the particular space but whole indoor temperature operation, so have the effect that the comfort level that keeps all even user of making of indoor temperature to feel improves.
