The specific embodiment
Below by accompanying drawing, embodiments of the present invention are described.In addition, in the following embodiments, the situation that is suitable for split type air conditioner is described, this air conditioner will be used for the air conditioning of living space as the oxygen enrichment device of gas enriching device.
(first embodiment)
At first, by Fig. 1, Fig. 2, Fig. 3, first embodiment of the present invention is described.Fig. 1 is the schematic perspective view of the gas enriching device of first embodiment of the present invention.In the first embodiment, adopt the situation of drawdown pump to be described to the differential pressure generating mechanism that in gas enriching mechanism, produces differential pressure.
This gas enriching device 30 is by the oxygen enrichment mechanism 1 that constitutes gas enriching mechanism, constitute the drawdown pump 2 of differential pressure generating mechanism, the path 3 of supplying gas, passage opening/closing valve 4 as passage opening/closing mechanism, as formations such as the temperature sensor 5 of temperature testing organization and controlling organizations 6, it is integrally contained in framework 7 inside.In addition, discharge to be responsible for 8 and to be connected, will be supplied to the position that they are used through the gas that gas enriching is handled with the discharge side of drawdown pump 2.The branched pipe 9 of passage opening/closing valve 4 by separating from the path 3 of supplying gas is connected with the path 3 of supplying gas, and simultaneously, the impedance compoment 10 that will circulate is connected with ingress pipe 11.Oxygen enrichment mechanism 1 also can be the permselective membrane that makes specific gas permeation selectively, also can be the selection adsorbed film of the specific gas of absorption.
In the gas enriching device 30 of such formation, suction as the drawdown pump 2 of the outlet side of the atmosphere 12 that will carry out first gas that gas enriching handles by being arranged at oxygen enrichment mechanism 1 enters oxygen enrichment mechanism 1, by the permselective membrane in the oxygen enrichment mechanism 1 etc., oxygen is seen through, become the second higher gas of oxygen concentration, enter the path 3 of supplying gas.Higher second gas of oxygen concentration, is discharged to discharge and is responsible for 8 through drawdown pump 2 from the path 3 of supplying gas.
In addition, the suction side in oxygen enrichment mechanism 1, promptly atmospheric side is provided with the fan (not shown), and this fan is used to remove the higher air of nitrogen concentration that is detained by oxygen enrichment mechanism 1, can make the running interlock work of this fan and gas enriching device 30.In addition, be used under the situation of air conditioner, also oxygen enrichment mechanism 1 can be arranged in the air-supply loop of off-premises station at for example gas enriching device 30, shared with outdoor fan.
In addition, the passage opening/closing valve 4 that is connected with branched pipe 9 can adopt open and close valves such as electromagnetism two-port valve, and circulation impedance compoment 10 can adopt capillary etc.The open and close controlling of passage opening/closing valve 4 is according to by the temperature sensor 5 detected temperature as temperature testing organization, and the signal by controlling organization 6 carries out.In addition, be connected with other equipment and under the situation about using at such gas enriching device 30, also can be according to control signal from the outside of these equipment, the switching of flow path open and close valve 4 is controlled.Passage opening/closing valve 4 also can be controlled in the following manner, and this mode is: only connect (ON), disconnect the opening and closing operations of (OFF), or and then change its switching degree, the flow of the gas by this open and close valve is controlled.In addition, any one temperature that temperature sensor 5 can detect near the atmospheric temperature that is provided with gas enriching device 30, the oxygen enrichment mechanism 1 temperature, the path 3 or discharge of supplying gas that constitutes gas enriching device 30 is responsible for 8 etc. road pipe temperature etc.
Below by Fig. 1, Fig. 2, Fig. 3, the gas enriching device 30 of said structure is arranged in the extraneous gas, the operation that makes atmosphere carry out oxygen enrichment is described.
If make drawdown pump 2 running, be drawn in the oxygen enrichment mechanism 1 as the outer gas 12 of first gas, it is by oxygen enrichment mechanism 1, and the air that oxygen concentration uprises is drawn in the drawdown pump 2 by the path 3 of supplying gas, and then is responsible for 6 and sends by discharging.
Below by Fig. 2, Fig. 3 the work that is clipped on the passage opening/closing valve 4 on the branched pipe of being located on the path 3 of supplying gas 9 is described.Fig. 2 is the schematic diagram of control method of passage opening/closing valve of the gas enriching device of first embodiment, and Fig. 3 is the sequential chart of the work of the passage opening/closing valve of this control method and drawdown pump.
The state of passage opening/closing valve 4 when the running beginning is in closed condition.If make drawdown pump 2 runnings, carry out the oxygen enrichment operation, then controlling organization 6 is according to passing through temperature sensor 5 detected extraneous gas temperature, and the on-off action of flow path open and close valve 4 is controlled.
Fig. 2 represents that the extraneous gas temperature that the top is detected is higher, more down, and the situation that the extraneous gas temperature is low more.As Fig. 2, shown in Figure 3, at first, detected extraneous gas temperature T is positioned at a point, and under the situation that is higher than set point of temperature T1, passage opening/closing valve 4 is in closed condition.On the other hand, externally gas temperature T reduces, and is in the state that b is ordered, and under the situation that is lower than set point of temperature T1, the relative humidity of extraneous gas also rises, and therefore, the relative humidity of rich oxygen containing second gas further rises.Thus, supplying gas path 3 or discharge to be responsible for 8 place's dewfall easily, following the situation such as freeze of this dew, producing phenomenon these pipe paths sealings.
So, if open passage opening/closing valve 4, then constitute with handle through gas enriching at least, compare by the gas of the path 3 of supplying gas, the extraneous gas 13 of the 3rd gas that relative humidity is less passes through ingress pipe 11, is sent in the path 3 of supplying gas.Thus, pass out to the lower extraneous gas of gas that discharge to be responsible in 8 and humidity and mix, to the direction variation that slows down the dewfall state.
At this moment, and compare by the situation of oxygen enrichment mechanism 1, the circulating resistance of the situation by ingress pipe 11 reduces.So if passage opening/closing valve 4 is in open mode, then extraneous gas is from oxygen enrichment mechanism 1 side, and from ingress pipe 11 sides, the preferential importing.Like this, the circulating resistance of this ingress pipe 11, circulation impedance compoment 10, passage opening/closing valve 4 and branched pipe 9 thus, can be sent into the extraneous gas of bigger flow less than the circulating resistance of oxygen enrichment mechanism 1.So, be stranded in the dew of discharging places such as the person in charge 8 and can be discharged to the outside, and can promote the dewfall evaporation of water by the wind speed that increases pipeline.And then, even just in case dew discharge to be responsible under the situation about freezing at places such as 8, still can high velocity air, it is discharged to the outside.
In this first embodiment, for the flow that is sent in the ingress pipe 11 is controlled, circulation impedance compoment 10 can be set also, form the flow that is fit to.In addition, by send into as the 3rd gas, its temperature is higher than the gas that sucks first gas in the oxygen enrichment mechanism 1, can more positively prevent the dewfall evaporation of water, prevents freezing of dew.
On the other hand, as shown in Figure 3, externally under the situation that gas temperature T rises once again, split the set point of temperature of closed channel open and close valve 4 and set a hysteresis.Promptly, externally under the situation that gas temperature reduces, passage opening/closing valve 4 is in open mode is set at the extraneous gas temperature T, control in the following manner, this mode is: even the c point in the process of extraneous gas temperature rising afterwards, the open mode of open and close valve does not return to closed condition, and when extraneous gas T rose to the state that d orders, open and close valve turned back to closed condition.Obviously, but also T1=T2 still, lag behind by setting, do not produce following situation, this situation refers to passage opening/closing valve 4 near T1, opens and closes the reliability of damage threshold, or because of frequent switching sound, the user does not feel well continually repeatedly.
In addition, also detected temperatures and a plurality of setting extraneous gas temperature of extraneous gas temperature can be compared, carry out the on-off action of passage opening/closing valve 4, the extraneous gas temperature is low more, prolongs more and opens the time, thereby can prevent the freezing of dew in these paths.
Also have, in the first embodiment,, in ingress pipe 11, be provided with the impedance compoment 10 that circulates as shown in Figure 1.Under the situation of impedance compoment 10 that do not circulate,, follow the violent suction pressure of drawdown pump 2 to change in when control of opening of carrying out passage opening/closing valve 4, produce bigger abnormal sound, still, can be by connecting circulation impedance compoment 10, reduce pressure and change, thereby can reduce such abnormal sound.And as above-mentioned, above-mentioned circulation impedance compoment 10 also can limit flow, constitute by the parts of its circulating resistance less than oxygen enrichment mechanism 1, and thus, be effective for eliminating of dew etc.
In the above description, temperature sensor 5 detected temperature are the extraneous gas temperature, but, by supply gas path 3 or discharge to be responsible for 8 etc. path temperature of employing, or near the extraneous gas temperature it, can realize preventing the effect of freezing etc. of generation, the dew of the dew in these paths really.
Have again, also can be according to irrelevant with the extraneous gas temperature, factor such as time is carried out the mode flow path open and close valve 4 of on-off action off and on and is controlled according to the rules.By such control, for example in air conditioner etc., the gas enriching device is set, can fresh atmosphere be switched towards indoor sending into the transmission of rich oxygen containing air, also can have ventilatory.
And then, gas enriching device in such structure is used under the situation of air conditioner etc., but the also temperature sensor that had of Personalized air conditioning machine itself, formation temperature sensor 5, in addition, also controlling organization 6 can be set according to the mode in the control device that is assemblied in the off-premises station in the air conditioner.
(second embodiment)
Below by Fig. 4, second embodiment is described.Fig. 4 is the schematic perspective view of the gas enriching device of second embodiment of the present invention.
In the path 3 of supplying gas, branched pipe 9 is set in the first embodiment, still, in the present embodiment,,, is connected with the suction side stream of drawdown pump 2 itself as the branched pipe 20 of gas introduction part as shown in Figure 4.In addition, passage opening/closing valve 4 grades are connected with branched pipe 20, and other structure is identical with first embodiment.
Second embodiment of the invention, process, need not on the path 3 of supplying gas 2, to carry out the processing of branch from oxygen enrichment mechanism 1 to drawdown pump by branched pipe 20 being arranged at drawdown pump 2 sides.On the other hand, when drawdown pump 2 is produced, the unit of passage opening/closing valve 4, branched pipe 20 etc. can be assembled in advance, the drawdown pump 2 that has the dew inhibit feature can be produced.
In the first embodiment, outside gas temperature is detected, thereby the work of flow path open and close valve 4 is controlled, but, such as, also can detect the load current of drawdown pump 2, judge dew generation, freeze and the discharge that causes is responsible for 8 stream and is stopped up and carry out work.
In addition, in the first embodiment, branched pipe 9 is arranged on the path 3 of supplying gas, and in second embodiment, branched pipe 20 directly is connected with the suction side stream of drawdown pump 2, still, also can directly be arranged in the oxygen enrichment mechanism 1.
(the 3rd embodiment)
Below by Fig. 5, the 3rd embodiment is described.Fig. 5 is the schematic perspective view of the gas enriching device of the 3rd embodiment of the present invention.
In first and second embodiments, become the differential pressure generating mechanism that the oxygen enrichment of gas enriching mechanism mechanism produces differential pressure as making, adopt drawdown pump as decompressor.In the 3rd embodiment, do not adopt decompressor, and adopt pressue device.That is, as shown in Figure 5, by pressue device such as, turbo fan 40 pressurizes to the extraneous gas 12 as first gas, through air-supply path 41, it is supplied to oxygen enrichment mechanism 42 as gas enriching mechanism.The higher gas of oxygen concentration as second gas of discharging from this oxygen enrichment mechanism 42 is discharged to the path 43 of supplying gas.Here, identical with the first, the second embodiment, oxygen enrichment mechanism 42 can adopt the adsorbent of selective air penetrating film or PSA method etc. etc., but particularly under the situation of hollow fiber membrane etc., the force (forcing) pump of this 3rd embodiment, or air-supply arrangement is effective as differential pressure generating mechanism.
In addition, according to passage opening/closing valve 44 being set, air-supply path 41 and the bypass loop 45 that is connected with the path 43 of supplying gas are set with oxygen enrichment mechanism 42 mode arranged side by side.In addition, also can in this bypass loop 45, the heater (not shown) be set, the gas by bypass loop 45 is heated.In addition, passage opening/closing valve 44 is identical with first and second embodiments, according to by temperature sensor 5 detected temperature, adopts controlling organization 6, and its switching is controlled, and this point is identical with first and second embodiments.
So, even under such situation that adopts pressue device as differential pressure generating, still can be by the on-off action of passage opening/closing valve 44, be implemented in the dews that taken place by oxygen enrichment mechanism 42 backs eliminating, freeze to prevent.
In addition, according to the 3rd embodiment, needn't be as first and second embodiments, a large amount of gas is drawn into the suction side of drawdown pump, thereby can suppress the situations such as abnormal sound generation that produce by suction, simultaneously, can be not to outside gaseous state, be under the atmospheric pressure situation about impacting, produce differential pressure.
Also have, second gas is sent into the method for supplying gas path or discharging in being responsible for be not limited to above-mentioned method, such as, also can consider in supply gas path or discharge are responsible for, injector is set, by the effect of this injector, the method that second gas is sucked, imports etc.
Have again, for the passage opening/closing valve of having described in first~the 3rd embodiment, though its opening and closing operations being carried out the method for electric control is described, but, also can be by such as marmem etc., form the valve member of passage opening/closing valve, this valve member is when becoming set point of temperature, and the distortion by marmem realizes on-off action.
(the 4th embodiment)
By Fig. 2, Fig. 6, the 4th embodiment of the on-off action that relates to the passage opening/closing valve is described.Fig. 6 is the passage opening/closing valve of the 4th embodiment and the working timing figure of pressure-reducing valve.The structure of describing in the structure of gas enriching device and first embodiment is identical, and it illustrates omission.
In addition, in the 4th embodiment, detecting by temperature sensor 5 under the situation of regulation extraneous gas temperature T 1, the on-off action of passage opening/closing valve 4 is turned round intermittently, before can passing through air dewfall oxygen enrichment mechanism 1, that relative humidity is higher, send into lower, the dry extraneous gas of a large amount of relative humidity, freeze preventing.
Said here extraneous gas refers to the air in the atmosphere, also can be extraneous gas or is provided with the ambient air of drawdown pump.
In the intermittent working of passage opening/closing valve 4, if the extraneous gas temperature is lower than T1, opening operation (ON operation) is carried out the ta time, then, carry out shutoff operation (OFF operation) the tb time.So, when externally gas temperature is higher than T2, passage opening/closing valve 4 cuts out, finish the intermittent working that opens and closes.
In addition, also the detected temperatures of extraneous gas temperature can be compared with a plurality of setting extraneous gas temperature, the extraneous gas temperature is low more, and the running rate of the on-off action of this passage opening/closing valve 4 is high more, thus can make dew in the pipeline freeze prevent that effect from improving.Have, here, the running rate of on-off action refers to the opening operation time shared ratio of intermittent working in the time again.
(the 5th embodiment)
By Fig. 7, Fig. 8, the 5th embodiment of the opening and closing operations that relates to the passage opening/closing valve is described.The structure of gas enriching device is identical with structure described in first embodiment, and it illustrates omission.
Fig. 7 is the control method schematic diagram of employing by the passage opening/closing valve 4 of the comparison of temperature sensor 5 detected extraneous gas temperature and design temperature, and Fig. 8 is by the passage opening/closing valve 4 of temperature sensor 5 detected extraneous gas temperature and the sequential chart of the work of drawdown pump 2.
Described identical with the 4th embodiment, if the extraneous gas temperature reduces, then can freeze, the blocked path of air by the dew of gas oxygen enrichment mechanism 1, that relative humidity is bigger.Thus, if temperature sensor 5 detects low outer temperature degree, then carry out the intermittent working of the on-off action of passage opening/closing valve 4, before passing through air dewfall gas enriching mechanism 2, that relative humidity is bigger, send into bigger, the dry extraneous gas of air quantity, prevent to freeze.At this moment, in the difference corresponding to the extraneous gas temperature, the situation that the extraneous gas temperature further reduces increases the running rate of intermittent working of the on-off action of passage opening/closing valve 4, prevents freezing in the stream.
As Fig. 7 and shown in Figure 8, in the 5th embodiment, for passage opening/closing valve 4, if the extraneous gas temperature is lower than T3, then carry out following switching A running, wherein, carry out opening action (ON running) the ta time of passage opening/closing valve 4, then, carry out the closing motion (OFF running) of tb time.If the extraneous gas temperature is higher than T4, then this passage opening/closing valve 4 cuts out, and the valve of the intermittent working that realization does not does not open and close cuts out running.On the other hand, so gas T1 situation about further reducing externally, carry out following switching B running, wherein, carry out opening action (ON running) the tc time of passage opening/closing valve 4, then, carry out closing motion (OFF running) the td time of passage opening/closing valve 4.As the opening action time ta of passage opening/closing valve 4 at this moment and the time relationship of tc is ta<tc, and, tc>td.
By adopting this mode, can be implemented in the lower situation of extraneous gas temperature, positively will supply gas path or discharge to be responsible in dew get rid of, realize steady running and do not produce the gas enriching device of abnormal sound etc.
(the 6th embodiment)

(the 7th embodiment)
Another embodiment to air conditioner with gas enriching device is described below.Figure 10 is the schematic perspective view of the structure of the air conditioner with gas enriching device of the 7th embodiment of the present invention.
In Figure 10, the air conditioner of the primary structure of air conditioner and the 6th embodiment identical adopted same label.
In Figure 10, off-premises station 51 comprises compressor 53; Compressor room 60 in this compressor room 60, is provided with the cross valve (not shown); The oxygen enrichment device, this oxygen enrichment device is formed by oxygen enrichment mechanism 61, drawdown pump 62 etc.; Electric component chamber 64 in this electric component chamber 64, is provided with the control device 63 of control air conditioner etc.Corresponding to these parts, be formed with the Machine Room.And, have the heat exchanger chamber 65 that constitutes by outdoor fan 55 and outdoor heat converter 54.
Indoor set 50 has indoor fan 52, and is provided with the outlet 57 of oxygen enrichment device.
The oxygen enrichment device comprises the oxygen enrichment mechanism 61 as selective air penetrating film; Drawdown pump 62, this drawdown pump 62 reduces the pressure of the primary side of oxygen enrichment mechanism 61; Oxygen supply is responsible for 66, and this oxygen supply is responsible for 66 and is connected between this oxygen enrichment mechanism 61 and the drawdown pump 62 in the mode that can ventilate; Triple valve 68, this triple valve 68 is connected in the way with atmosphere ingress pipe 67 and this oxygen supply person in charge 66; Discharge to be responsible for 69, this is discharged and is responsible for 69 and is connected with the discharge side of drawdown pump 62.Here, the atmosphere introducing port 70 of the end of atmosphere ingress pipe 67 is provided with according to the mode of stretching out in the inside of compressor room 60.
Ajutage 71 is will discharge to be responsible for 69 pipelines that are connected with outlet 57, and it is sent gas from off-premises station 51, then, it is sent to the inside of indoor set 50.
In addition, the primary side (atmospheric side) in oxygen enrichment mechanism 61 is provided with the fan (not shown) of the air that is rich in nitrogen that is used to remove delay, can make the running interlock work of itself and oxygen enrichment device.Here, the primary side of oxygen enrichment mechanism 61 is arranged in the air-supply circuit of heat exchanger chamber 65 of the outdoor fan 55 with off-premises station 51, by the air-supply of outdoor fan 55, the air that is rich in nitrogen of the primary side of oxygen enrichment mechanism 61 is removed.
According to said structure, if make drawdown pump 62 runnings, suction is as air first gas, in the heat exchanger chamber 65, by oxygen enrichment mechanism 61, as oxygen containing second gas of richness, by the oxygen supply person in charge 66, triple valve 68, be drawn in the pressure-reducing valve 62, by discharging the person in charge 69, ajutage 71,, deliver to the inside of indoor set 50 successively from outlet 57.
In addition, triple valve 68 is in the open mode circulating resistance of (be called atmosphere ingress pipe 67 and be responsible for 66 states that are communicated with the oxygen supply of drawdown pump 62), is in the circulating resistance of closed condition (the oxygen supply person in charge 66 who is called oxygen enrichment mechanism 61 sides is responsible for 66 states that are communicated with the oxygen supply of drawdown pump 62 sides) less than triple valve 68.So if triple valve 68 is in open mode, then atmosphere is from oxygen enrichment mechanism 61 sides, and preferentially imports from the atmosphere introducing port 70 of atmosphere ingress pipe 67.And, the part that resistance is less, by the situation of oxygen enrichment mechanism 61, can import more substantial air relatively, improve so be stranded in the wind speed of dew in pipeline of discharging places such as the person in charge 69, be expressed into outlet 57 sides easily, simultaneously, wind speed improves, and evaporation capacity also rises, like this, can reduce dew.In addition, even just in case dew freezes also can pass through wind speed under the situation in path, will freeze is expressed into outlet 57.
