In addition, the rotating shaft of Sirocco fan 20d is mounted to axle horizontal on the 1st passage R, with the mobile forced ventilation stream of brute force.
Make the air interchanger 10 of this structure carry out forced ventilation and make it carry out the gas exchange action of natural ventilation referring now to the flowchart text of the experimental data of Fig. 5 and Fig. 6 etc.
Now, chamber A, B ... Deng the heating that is set as about 20 ℃, and open-air is set as the temperature about 5 ℃.
Under this heating state, chamber A, B ... Deng atmospheric density lower than open-air density, as shown by arrows, produce from the bottom to the buoyancy on top.Because of this buoyancy, and from air entry 11a, 11b, 11c, 11d ... make the inside in the air inflow house 11 outside the room, make chamber A, B ... internal air pressure improve, the air-breathing peristome 14a by air interchanger 10 etc., ventilation framework 13, throttle setting 18, flow to outside the room naturally as the 2nd passage N of natural ventilation passage or as the 1st passage R of forced ventilation passage, discharge duct 22, exhaust tower 24.Sensor 19aa, 19ab by control device 19 detect this ventilation air quantity Q.
Yet,, in general house, be less than 100m though ventilation air quantity Q also depends on the size of chamber A etc. 3/ h, it is insufficient to be considered to take a breath, at 100m 3/ h to 180m 3In/h the scope, be considered to suitable ventilation, if be in 180m 3More than/the h, just think too much slightly.
Based on this master data, throttle setting 18 has been studied by experiment the relation of the aperture of standard-sized sheet ventilation air quantity Q and air door 18a.Fig. 5 is its result.In view of the above, in general control, Q is 0m when the ventilation air quantity 3/ h to 180m 3In the time of in/h the scope, just in advance the aperture of air door 18a is placed 90 ° (standard-sized sheets).In addition, when being 180m at the ventilation air quantity Q that flowed 3/ h to 225m 3Under the situation in the/h scope,, then can be placed on 100m if the aperture of air door 18a is placed 60 ° 3/ h to 180m 3In/h the scope.
If following when equally reducing the aperture of air door 18a successively, then ventilation air quantity Q can be placed 100m along with the increase of ventilation air quantity Q 3/ h to 180m 3In/h the scope.
Q is in 450m when the ventilation air quantity 3When/h is above,, be in abnormality,, stop gas exchange action so close air door 18a because of indoor, outdoor ventilation air quantity Q too uprises.
In addition, want to increase the occasion of taking a breath in humidity, the higher places of foul smell such as the occasion of ventilation air quantity Q or dining room the user, utilize the switching controls of control device 19 and switch to the 2nd ventilatory pattern (powerful control), to strengthen ventilation from the 1st ventilatory pattern (general control).
In the 2nd ventilatory pattern, ventilation air quantity Q is less than 180m 3/ h just is in deficiency, at 180m 3/ h to 260m 3In/h the scope, just be in suitable ventilation, at 260m 3More than/the h, just too much.This experimental result has also disclosed the situation of powerful control in the bottom of Fig. 5.
Try to achieve the relation of the essential switching angle of ventilation air quantity Q and air door 18a from these data, the selection control of throttle setting 18 grades is carried out in the selection control output of decision control device 19,
From this ventilation characteristic will take a breath air quantity Q, for example for 100m 3The occasion of/h is as the 1st setting value, with 180m 3The occasion of/h will be less than the 100m of the 1st setting value as the 2nd setting value 3/ h is as hypoventilation, with the 100m of the 1st setting value 3The 180m of/h to the 2 setting values 3Take a breath as suitable in the/h scope, with the 180m of the 2nd suitable definite value 3The above ventilation of/h is taken a breath as surplus, and the situation of concrete selection control throttle setting 18, pressure fan 20 is described.
When sensor 19aa, 19ab to 100m 3/ h to 180m 3When the ventilation air quantity Q the in/h scope detects,, so as shown in Figure 6, throttle setting 18, pressure fan 20 are not controlled (S1) because it is suitable ventilation air quantity Q.
This be because, air door 18a opens with suitable aperture (almost standard-sized sheet), scavenging flow carries out air-breathing to the ventilation air from air-breathing opening 14a, become the ventilation of natural ventilation pattern by the 2nd passage N and the 1st passage R, discharge duct 22 and exhaust tower 24, and air is emitted outside the room.
Therefore, just need not obtain energy-conservationization with the power consumption of this ventilation, and owing to pressure fan 20 does not turn round, so no running noise can be taken a breath under the state of low noise.
When sensor 19aa, 19ab detect ventilation air quantity Q less than 100m 3During/h, because it is hypoventilation, so as shown in Figure 6, control device 19 must rotate pressure fan 20 by selecting control forced ventilation pattern, carries out the forced ventilation of chamber A etc.
If become this state, then carry out forced ventilation control (S2), (S3), (S4) that Sirocco fan 20c running is stopped after about 1 hour.
Utilize this forced ventilation, scavenging flow just becomes the ventilation of the forced ventilation pattern of main air-breathing peristome 14a, secondary air-breathing peristome 14c, 14d, bottom ventilation framework, throttle setting 18, pressure fan 20, secondary exhaust port body 26, top ventilation framework, the 14b of exhaust port portion etc., and flow to outside the room by discharge duct 22, exhaust tower 24 by the 1st passage R, carry out forced ventilation.
Carry out this ventilation running, Q becomes 100m up to the ventilation air quantity 3/ h to 180m 3Till the suitable ventilation in the/h scope.For this ventilation, though pressure fan 20 produces running noise, this noise is difficult to be delivered to chamber A etc. because of the control device 19 that is configured in motor 20 bottoms, so can not bring sense of discomfort to the user.But, because this forced ventilation control makes motor 20 runnings, so become the ventilation of power consumption.
In addition, though the rotation of general speed is carried out in the rotation of pressure fan 20, Q is less than 50m at deficiency ventilation air quantity 3Under the situation in the/h scope, the air quantity Q that will take a breath apace is controlled to 100m with rotating at a high speed to utilize the control of control device 19 3/ h to 180m 3In/h the scope, at 180m 3Under the above situation of/h, also available low speed rotation and the air quantity Q that will take a breath at leisure is controlled to 100m 3/ h to 180m 3In/h the scope.
In addition, detect ventilation air quantity Q less than 180m as sensor 19aa, 19ab 3During/h, control device 19 must carry out closing control to the air door 18a of throttle setting 18 by the selection control selecting control natural ventilation pattern to stop the rotation running of motor 20 and utilize control device 19, suppresses ventilation air quantity Q (S5), (S6).
The closing control of this air door 18a is based on described experimental data, if ventilation air quantity Q is 180m 3/ h to 225m 3In/h the scope, then select control to be closed into 60 ° air door 18a, if ventilation air quantity Q is 225m 3/ h to 300m 3In/h the scope, it is at 45 etc. then air door 18a to be selected control to close, and keeps its state about 1 hour, then, detects standard-sized sheet ventilation air quantity Q, carries out (S5), (S6), (S7), (S8) till becoming suitable ventilation air quantity Q repeatedly.
If become appropriate value, then air door 18a is kept placing the state of standard-sized sheet.But then, even air door 18a is placed standard-sized sheet, if ventilation air quantity Q is too not enough, then carry out forced ventilation, rotation control fan 20c is with its correction (S5), (S2), (S3), (S4).Like this, can obtain suitable ventilation air quantity Q.
In above-mentioned forced ventilation, also can be with air door 18a with suitable angles such as 60 °, 45 °, 30 ° towards pressure fan 20, scavenging flow reliably leads.
In addition, for the detection that does not hinder sensor 19ab too to influence to the clockwise direction counter-rotating because of air door 18a, thus in air door, be provided with the block (not shown) that constitutes in full week roughly by raised line, with the excessive rotation of restriction air door 18a.
The control of above-mentioned air door 18a though be to select best control, also can be undertaken by closing control of doing successively as shown in Figure 7 to close and the FEEDBACK CONTROL of doing successively to open of opening control.
This control is taken a breath air quantity Q less than 180m when sensor 19aa, 19ab detect 3During/h, at first air door 18a being closed into 60 °, even so, is 180m if still detect ventilation air quantity Q 3When/h is above, air door 18a is closed at 45, be closed into 30 ° etc. again, till becoming suitable ventilation air quantity Q, detect, judgement, closing control (S5), (S17).By this control,, then stop the rotation control of air door 18a if reach suitable ventilation air quantity Q.
But, big if this closing control becomes, become less than 100m 3The deficiency of/h ventilation air quantity Q then is opened to 45 ° of apertures with air door 18a from 30 ° of apertures on the contrary, is opened to 60 ° of apertures etc. from 45 ° of apertures again, and that carries out air door 18a opens control (S5), (S9), (S18).By this control, can prevent from too to close and carry out suitable ventilation.
Even the aperture to 90 of air door 18a ° (standard-sized sheet) is if ventilation air quantity Q is less than 100m 3/ h and deficiency are then carried out forced ventilation by fan 20c rotation, increase ventilation air quantity (S9), (S2), (S3), (S4).So just can obtain suitable ventilation air quantity Q.
When the air outside the room has high wind sometimes, can flow back to chamber A, B etc. by discharge duct 22, air interchanger 10 from exhaust tower 24.
This state has the sensor 19ab of peristome just it can be carried out suitable detection as dynamic pressure by using on top.As shown in Figure 8, by control device 19 this detected value being obtained as electric signal v, is under the situation of v＜0 in electric signal, judge that this ventilation air quantity Q is contrary wind, thereby pressure fan 20 carries out forced ventilation, prevents (S22), (S23), (S24) against the wind.
This control method is because identical with the forced ventilation control of fan 20c, and the Therefore, omited describes in detail.For this ventilation control, be under the situation of 0≤v≤0.05 in electric signal, Q is less than 100m as the ventilation air quantity 3The ventilation of the deficiency of/h, then pressure fan 20 carries out the forced ventilation running, also can eliminate this Hypoventilated phenomenon (S25), (S22), (S23), (S24), and is under the situation of v＞0.05 in electric signal, is 100m as the ventilation air quantity 3More than/the h, then control device is selected the natural ventilation pattern, does not make pressure fan 20 rotation (S26), (S27).
As mentioned above, because throttle setting 18, pressure fan 20 are controlled by the selection of control device 19 house 11 are carried out the ventilation of forced ventilation pattern, and as required, take a breath by the natural ventilation pattern that adopts natural ventilation as much as possible, so can advance energy-conservationization of air interchanger 10 effectively.
In addition,, just can reduce the running of pressure fan 20, obtain low noiseization by using the natural ventilation pattern.
In addition, in above-mentioned each example, be to be made as 100m with the 1st 3/ h, be made as 180m with the 2nd 3/ h's, but, can freely set 180m for the 1st according to user's hope 3/ h, set 260m for the 2nd 3/ h etc.
In addition, be that ventilatory pattern is set as the general control model of the 1st ventilatory pattern with as the powerful control model of the 2nd ventilatory pattern, but also can freely the 1st and the 2nd ventilatory pattern be set as than more weak pattern of general control model or the pattern stronger than powerful control model.
