The specific embodiment
The present invention is more completely described with reference to the accompanying drawings, exemplary embodiment of the present invention shown in the accompanying drawing.But the present invention can implement by a lot of different modes, and should not be construed as the embodiment that is subject to here to be proposed.In addition, the embodiment that is provided be more thorough in order to expose, can more completely notion of the present invention be conveyed to those skilled in the art.Identical mark is represented similar element in the accompanying drawing, and therefore the descriptions thereof are omitted.
As mentioned above, Fig. 2 schematically shows the schematic diagram of pipe-connection searching apparatus according to an exemplary embodiment of the present invention.
With reference to Fig. 2, the pipe-connection searching apparatus of multi-type air conditioning system can comprise: a plurality of temperature sensors 111 are separately positioned in the corresponding indoor unit of a plurality of indoor units 110; Unit 120 is opened/closed to pipeline, is used for when outdoor unit 130 work, and each of a plurality of pipelines that will be connected with outdoor unit 130 in next a mode is opened; And pipeline search unit 131, be used for after outdoor unit 130 and pipeline are opened/closed unit 120 and start working, compare with other indoor unit and temperature sensor with identification by the temperature sensor search, temperature signal at first satisfies the indoor unit of predetermined set value.
The variation of temperature sensor 111 detected temperatures, and therefore produce corresponding output voltage, indicate detected variations in temperature.At this, preferred employing is arranged on the known temperature sensor in the indoor unit usually.
Pipeline is opened/is closed unit 120 and comprises a plurality of valves, is used for optionally opening or closing a plurality of pipelines that are connected with outdoor unit 130.In order to realize required function, when outdoor unit 130 work, pipeline is opened/is closed unit 120 and once only opens a pipeline.Therefore preferably, pipeline search unit 131 control pipeline search procedures comprise that pipeline opens/close unit 120.But those skilled in the art expect easily, carry out such control by other parts in an alternative embodiment.
In another embodiment, unit 120 is opened/closed to the manually actuated pipeline of the setter of multi-type air conditioning system.But pipeline is opened/is closed unit 120 and for example automatically opens or closes pipeline by the control of pipeline search unit 131, as mentioned above preferably.
In addition, because each pipeline opens and closes successively, thus the process that is connected between the pipeline that repeats to check each indoor unit 110 and the outdoor unit 130, and determine and temperature and/or variations in temperature that the corresponding pipeline of opening is associated.Certainly, setter can each indoor unit of manual examination (check) temperature or variations in temperature, but preferably, the corresponding electrical wiring of setter by extending out from indoor unit with the outdoor unit connection, receive the information of the temperature sensor of each indoor unit, check the state of indoor unit.In this way, setter can be searched for according to the position of outdoor unit.
In one embodiment, the pipeline search unit is in outdoor unit 130.Perhaps, the pipeline search unit also can be in any indoor unit.
Describe below and allow setter to determine two exemplary configuration whether electric wire suitably connects.According to first exemplary configuration, the electrical wiring display unit is set, so that setter can be set up tie point between the electrical wiring that is associated in the indoor unit that outdoor unit and temperature sensor at first satisfy setting value with visual means.According to second exemplary configuration, the electrical wiring matching unit is set, be used for the pipeline when front opening is complementary with the corresponding indoor unit that temperature sensor at first satisfies setting value.
In first exemplary configuration, the electrical wiring display unit shows outdoor unit 130 and corresponding to the tie point between the electrical wiring of the indoor unit 110 of the pipeline of opening.The electrical wiring display unit can be arranged on the connection status that shows electrical wiring in outdoor unit 130 places or the outdoor unit 130, makes setter correctly to connect electric wire, and it is described to see below Fig. 3.
With reference to Fig. 3, between outdoor unit 130 and a plurality of indoor unit 110a, 110b, 110c, form space 140, be used for pipe laying and electrical wiring, this makes setter be difficult to check the arrangement of pipeline and electrical wiring.Particularly, under the floor, in pillar or the ceiling, be not easy to see the space 140 that is used for pipe laying and electrical wiring.For the purpose of clearly demonstrating, Fig. 3 is not shown be arranged in the outdoor unit or outdoor unit near pipeline open/close part.
In order to search for and discern corresponding pipeline, electric wire and indoor unit, be that corresponding mutually pipeline and electrical wiring is connected to outdoor unit 130 with hope.Then, open first pipeline, pipeline A for example, and other pipeline B, C keep closing.Afterwards, when outdoor unit 130 work, electrical wiring shows will show which electrical wiring and corresponding indoor unit 110a, 110b, 110c at first satisfy setting value.Therefore, determine which indoor unit is connected to the pipeline A that opens.
In the exemplary configuration of Fig. 3, electrical wiring display unit 133 is arranged in outdoor unit 130 places or the outdoor unit 130.As shown in the figure, electrical wiring display unit 133 is connected to corresponding indoor unit 110 by electrical wiring.Electrical wiring display unit 133 can show the temperature of indoor unit 110, perhaps can also show the feature (identity) of the electrical wiring that is associated with the indoor unit that satisfies setting value, for example by flash of light.That is to say that electrical wiring display unit 133 shows and the corresponding position of electrical wiring in outdoor unit place or outdoor unit of indoor unit of at first satisfying setting value.Among Fig. 3, if the electrical wiring display unit 133a corresponding with the pipeline A that opens lights, then electrical wiring correctly connects.But, if electrical wiring display unit 133b or 133c light, electrical wiring incorrect link then.Therefore, setter can change the electrical wiring connection subsequently.Connect though setter can change pipeline, be connected with the change electric wire and compare, like this may be more complicated.In addition, when changing the pipeline connection, may reduce bonding strength.Therefore preferably, change electrical wiring connection rather than the connection of change pipeline.
Shown in the configuration of Fig. 3, for each pipeline, repeatedly order opens and closes the process of a plurality of pipelines.Therefore, can examine, if necessary, can correctly connect the electrical wiring corresponding with all pipelines.
In second exemplary configuration, adopt the electrical wiring matching unit.At this, setter needn't change electrical wiring and connect.Electrical wiring changes into from being dynamically connected, with corresponding pipeline coupling.This makes installation process very efficient.Fig. 4 illustrates electrical wiring matching unit 135.Electrical wiring matching unit 135 directly is connected with the electrical wiring that extends out from indoor unit, perhaps is connected with the electrical wiring display unit 133 that is arranged between them.
In the example of Fig. 4, when pipeline A opens, carry out the pipeline search procedure, and the electrical wiring matching unit is complementary pipeline A with the electrical wiring that is connected to electrical wiring display unit c.This is because the indoor unit corresponding with electrical wiring and electrical wiring display unit c is first indoor unit that satisfies setting value.Particularly, when pipeline that inspection is opened, carry out search procedure, the electrical wiring matching unit switches electrical wiring, makes the electrical wiring that connects another pipeline (for example pipeline C) be connected to the pipeline of opening (for example pipeline A) now.
When adopting the method for this configuration and correspondence, setter does not need to change the connection between the electrical wiring afterwards of pipeline search procedure.Therefore, carry out automatically pipeline close with open, being connected again of pipeline search procedure and any electrical wiring.
In addition, in case pipeline opens and closes, then do not need to comprise after tested pipeline with corresponding electrical wiring that the test subsequently of other pipeline is complementary.
Temperature sensor value is used to carry out the pipeline search procedure.Even not when the indoor unit of being searched for provides cold-producing medium, provide the temperature of the indoor unit of cold-producing medium also can very fast change.Therefore in the search procedure of other pipeline, the temperature sensor of the indoor unit of being searched at first senses predetermined set value probably.Therefore preferably, in the search procedure of other pipeline, get rid of pipeline and the indoor unit searched for.
Indoor fan circulates air in the space that indoor unit is installed.When fan running, measure the temperature in this space rather than the internal temperature of indoor unit.Therefore preferably, when carrying out the pipeline search procedure, just when the pipeline search unit was worked, indoor fan did not turn round.In this case, the temperature sensor of indoor unit can be measured the variation of indoor unit internal temperature exactly and not be subjected to the influence of external environment condition.
The temperature of measuring the space that is associated with given indoor unit makes it possible to search for corresponding pipeline, but this is not a preferred version, because need the long-time setting value that satisfies.More preferably at operation office for train receiving departure internal fan not with measure under the internal temperature of indoor unit itself, carry out search procedure.In addition preferably, in order to measure the internal temperature of indoor unit more accurately, close the outlet (vent) of indoor unit.
In the pipeline search procedure, can use multiple setting value.
According to first exemplary embodiment, the variations in temperature that can adopt indoor unit is as setting value.
Particularly, pipeline is opened/is closed unit 120 and opens ducted one that is connected with outdoor unit 130.Outdoor unit 130 is started working then.Before outdoor unit 130 was started working, the temperature sensor 111 that is associated with each indoor unit 110 was measured the internal temperature of corresponding indoor unit 110.After outdoor unit 130 is started working, utilize temperature sensor 111 to determine which indoor unit at first reaches predetermined variations in temperature.This indoor unit is confirmed as the unit that is connected with the pipeline of opening.
Predetermined temperature difference can be stored in the pipeline search unit, perhaps, setter can manually be provided with predetermined temperature difference according to installation environment.The scope of predetermined temperature difference can be 5 degrees centigrade to 15 degrees centigrade.If predetermined temperature difference is lower than 5 degrees centigrade, Search Error just appears probably.This is because another indoor unit (not being the indoor unit corresponding with the pipeline of opening) may at first reach this temperature difference.Therefore preferably, temperature difference is set at greater than 5 degrees centigrade.
Even, also have the cold-producing medium of minute quantity to flow through all pipelines usually, so above-mentioned mistake can occur because when closing other pipeline opening a pipeline.For fear of this mistake, preferably, temperature difference is equal to or greater than 5 degrees centigrade, and wherein, the result of pipeline search procedure is more reliable.
If predetermined temperature difference is very big, it is also very long then to carry out the needed time of pipeline search procedure.Therefore preferably, predetermined temperature difference is not more than 15 degrees centigrade.
Can measure the temperature difference of given indoor unit by comparing preceding temperature of opening conduits and the real time temperature measurement result after the opening conduits.Can measure temperature difference in real time with predetermined time interval.When adopting 15 degrees centigrade temperature difference, particularly useful like this as predetermined set value.
Be operated under the refrigeration mode or be operated in can under the heating mode for outdoor unit in the pipeline search procedure.
Describe pipeline below with reference to Fig. 5 and connect search procedure.At first,, open a plurality of ducted pipelines, and other pipeline keeps closing at step S110.At step S120, each indoor unit is measured initial temperature, outdoor unit is started working then.Initial temperature with each indoor unit is stored in the predetermined memory cell then, up to finishing comparison procedure.Initial temperature can be before outdoor unit is started working, measured as mentioned above, also initial temperature can be when outdoor unit is started working, measured.
At step S130, for example measure the temperature of back in real time for each indoor unit then with predetermined time interval.At step S140, the temperature difference between the real time temperature of each indoor unit calculating initial temperature and back based on the result of calculation of these temperature differences, determines whether to satisfy the indoor unit of predetermined temperature difference.If determine not satisfy the indoor unit of predetermined temperature difference, then repeat two steps in front.
At step S150, if determine that one of them indoor unit satisfies predetermined temperature difference, then the electrical wiring that manually or automatically will be associated with this indoor unit is connected to the pipeline of opening.
At step S160, all be examined if not all pipelines, then at step S170, only open ducted one of residue, close remaining pipes.From measuring the process of initial temperature, whole process repeated.
As a reference, last pipeline to be matched does not need to check, because only surplus next indoor unit.At this moment, last remaining pipeline and the electrical wiring that is associated with remaining indoor unit are complementary.In addition, as mentioned above, repeat in the pipeline search procedure preferred pipeline and the indoor unit of getting rid of previous coupling in the back.
According to second exemplary embodiment, can adopt the predetermined kelvin rating different as setting value with the temperature value of outdoor unit before starting working.In the present embodiment, in each indoor unit or remaining indoor unit, measure temperature by the temperature sensor of correspondence.By carrying out these measurements, can determine which indoor unit at first reaches predetermined temperature value.Then, the definite indoor unit that at first reaches predetermined temperature value of pipeline search unit is exactly the indoor unit that is connected with the pipeline of opening.Then, the electrical wiring that manually or automatically will be associated with this indoor unit is complementary with the pipeline of opening.Present embodiment has following advantage.When setter utilizes electrical wiring display unit (wherein display unit is used to show the temperature that is associated with each indoor unit) manually to change electrical wiring to be connected, setter can more easily be checked the temperature that is associated with each indoor unit, more easily determines the connection status of indoor unit.According to present embodiment, before opening outdoor unit, needn't carry out temperature survey.Only need to determine which indoor unit at first reaches predetermined temperature value.Setter one sees which indoor unit at first reaches predetermined temperature on display, just can easily carry out electrical wiring and connect.
According to second exemplary embodiment, before the pipeline search procedure begins, must determine the mode of operation of outdoor unit earlier in addition, just definite outdoor unit is under the refrigeration mode or is under the heating mode.Make predetermined temperature value be higher than current room temperature (being the temperature value of temperature sensor before outdoor unit is started working) if carry out the pipeline search procedure, then outdoor unit will be operated under the heating mode.Otherwise if predetermined temperature value is lower than current room temperature, then outdoor unit will be operated under the refrigeration mode.
In addition, because temperature value can change according to Current Temperatures, so preferably set up database, the predetermined temperature value that storage is associated with Current Temperatures.
In addition, as the exemplary embodiment of front, preferably in current repetition pipeline search procedure, the pipeline search unit is got rid of the pipeline that searches previously.So just simplified each repetition of back, because the temperature value that will check still less.In addition, the temperature that is connected to the indoor unit of the pipeline that has mated may still be predetermined temperature value, determines difficulty thereby cause in the repetitive process of back.
Similar to exemplary embodiment shown in Figure 2, outdoor unit can comprise the electrical wiring display unit, is used for showing outdoor unit and being associated with tie point between the electrical wiring of the indoor unit that at first reaches predetermined temperature value to setter.Perhaps, outdoor unit can comprise the electrical wiring matching unit, automatically pipeline of opening and the electrical wiring that is associated with the indoor unit that at first reaches predetermined temperature value is complementary.
In addition, as first exemplary embodiment,, in this process, preferably close or turn-off the outlet and the fan that are associated with each indoor unit in order to minimize any influence that temperature sensor produces because of external environment condition (being the indoor unit outside).
Below with reference to Fig. 6 the operation that is associated with second exemplary embodiment is described simply.At first at step S210, optionally opening conduits is just opened a pipeline, closes remaining pipes.At step S220, outdoor unit is started working.Then at step S230, measure the internal temperature that is associated with each indoor unit or remaining indoor unit.Then, whether at step S240, determining has one to satisfy predetermined temperature value in the remaining indoor unit.If no,, carry out temperature survey once more then at step S230.At step S250,, determine that then this indoor unit is connected to the pipeline of opening, and the electrical wiring that is associated with this indoor unit manually or automatically can be complementary with the pipeline of opening, as mentioned above if one of them indoor unit satisfies predetermined temperature value.At step S260 and S270, remaining pipeline is repeated said process, up to all pipelines of coupling.
According to the 3rd exemplary embodiment, can adopt absolute temperature and temperature difference simultaneously.For example, different with the temperature value of outdoor unit before starting working when at least one indoor unit at first satisfies predetermined temperature value, can adopt maximum temperature difference in the temperature difference that indoor unit records as setting value.Therefore, setting value is not a fixed value, but the maximum temperature difference in the temperature difference that remaining indoor unit records.
Particularly, open outdoor unit.Just before opening outdoor unit or similar simultaneously, the initial temperature of the corresponding indoor unit of each temperature sensor measurement.Afterwards, temperature sensor continues to measure the temperature of corresponding indoor unit.When first indoor unit reached predetermined temperature value (first setting value), the corresponding initial temperature that records before the measured temperature that temperature sensor is extracted and the opening conduits compared.The indoor unit of temperature difference maximum is defined as connecting that indoor unit of the pipeline of opening.
The operation of the 3rd embodiment is described below with reference to Fig. 7.At first as the embodiment of front, in step S310 opening conduits optionally.At step S320, measure the initial temperature of each indoor unit then, similar simultaneously or after a while, outdoor unit is started working.At step S330, carry out the temperature survey of back for each indoor unit then.At step S340, one of them indoor unit satisfies predetermined temperature value (first setting value) at last.When indoor unit satisfies predetermined temperature value, analyze poor between the measured temperature of the initial temperature of each indoor unit and back, determine which indoor unit has experienced maximum variations in temperature (being the temperature difference maximum).At step S350, determine that this indoor unit is for connecting the indoor unit of the pipeline of opening then.Then this information is used for manually or automatically will being associated with the electrical wiring of this indoor unit and the pipeline coupling of opening.At step S360 and S370, repeat said process, all mate up to remaining pipeline.
In addition, outdoor unit can comprise the electrical wiring display unit, shows outdoor unit and has tie point between the electrical wiring of indoor unit of maximum temperature difference to setter.Setter can be manually be complementary electrical wiring with corresponding pipeline then.Perhaps, outdoor unit can comprise the electrical wiring matching unit, is used for automatically pipeline of opening and the electrical wiring with indoor unit of maximum temperature difference being complementary.In addition as mentioned above, in the pipeline search procedure, preferably close or outlet and fan that shutoff is associated with indoor unit.In addition as mentioned above, the pipeline and the indoor unit that have mated of preferred eliminating.
According to the 4th exemplary embodiment, for each indoor unit, temperature difference maximum in the temperature difference that the serviceability temperature sensor records is as setting value.Particularly, in case outdoor unit work preset time cycle (first setting value), just determine poor between the temperature that each temperature sensor records before and after outdoor unit is started working.The indoor unit of variations in temperature maximum (being the temperature difference maximum) is confirmed as connecting the indoor unit of the pipeline of opening.
