As it is shown in figure 1, the method for this control air-conditioner comprises the steps:
Step S102, the running status of detection air-conditioner.
Step S104, it is judged that whether the running status of air-conditioner is preset operating state, wherein, preset operating state is that air-conditioner is in refrigerating operaton process, and running status when compressor quits work.
Step S106, when judging that the running status of air-conditioner is preset operating state, controls air-conditioner and the auxiliary device of air-conditioning internal machine is heated, so that the surface temperature of the auxiliary device of air-conditioning internal machine is more than the dew point temperature in the air channel of air-conditioning internal machine.
The auxiliary device of air-conditioning internal machine includes heat-generating pipe, etc.
When air-conditioner runs, if the surface temperature of the auxiliary device of air-conditioning internal machine is lower than the dew point temperature in the air channel of air-conditioning internal machine, the surface of the auxiliary device of air-conditioning internal machine there will be the globule of condensation, and these globules drip on the blower fan of air-conditioning, can cause that air-conditioning blows water. When air conditioner heat-production runs, the surface temperature of the auxiliary device of air-conditioning internal machine is higher, it will usually higher than the dew point temperature in the air channel of air-conditioning internal machine, now, and the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, is not result in air-conditioning and blows water. When air-conditioner refrigerating operaton, the surface temperature of the auxiliary device of air-conditioning internal machine is relatively low, it is possible to can lower than the dew point temperature in the air channel of air-conditioning internal machine. When the surface temperature of auxiliary device of air-conditioning internal machine is lower than dew point temperature in the air channel of air-conditioning internal machine, the surface of the auxiliary device of air-conditioning internal machine there will be the globule of condensation, and these globules drip on the blower fan of air-conditioning, can cause that air-conditioning blows water.
After the operational mode of user setup air-conditioner is refrigerating operaton, the compressor of air-conditioning opens (namely starting working), indoor temperature declines, after indoor temperature drops to the first preset value (the first preset value be the target temperature value of user setup or slightly below the temperature value of target temperature value of user setup), the compressor of air-conditioning quits work (being in holding state), hereafter, indoor temperature rises, after indoor temperature rises to the second preset value (the second preset value is a temperature value more than the first preset value), the compressor of air-conditioning is started working again, indoor temperature declines. preset operating state in the embodiment of the present invention refers to that air-conditioner is in refrigerating operaton process, and running status when compressor quits work. in general, air-conditioner has in refrigerating operaton process and is repeatedly in preset operating state, and the time that air-conditioning is repeatedly in preset operating state is the discontinuous time period.
Such as, when 10:00, indoor temperature is 30 DEG C, now user uses the operational mode that remote controller arranges air-conditioner to be refrigerating operaton and to arrange target temperature be 22 DEG C, the compressor of air-conditioning is opened, and indoor temperature declines, when 10:30 indoor temperature drops to 21 DEG C, the compressor of air-conditioning quits work, hereafter, indoor temperature is slowly gone up, when 10:35 indoor temperature is 23 DEG C, the compressor of air-conditioning is started working again, and indoor temperature declines. When 10:37 indoor temperature drops to 21 DEG C, the compressor of air-conditioning quits work, and when 10:43 indoor temperature is 23 DEG C, the compressor of air-conditioning is started working again. In this example, air-conditioning is in refrigerating operaton process at 10:00-10:43, and the time period that the running status of air-conditioner is preset operating state has two, is 10:30-10:35 and 10:37-10:43 respectively.
The method controlling air-conditioner that the embodiment of the present invention provides is by when air-conditioner is in preset operating state, control air-conditioner the auxiliary device of air-conditioning internal machine is heated, so that the surface temperature of the auxiliary device of air-conditioning internal machine is more than the dew point temperature in the air channel of air-conditioning internal machine, thus the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, so after the compressor of air-conditioning reopens, even if the surface temperature of the auxiliary device of air-conditioning internal machine declines to some extent, remain on more than the dew point temperature in the air channel of air-conditioning internal machine, the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, thus avoiding the occurrence of the problem that air-conditioning blows water.
And, the method controlling air-conditioner that the embodiment of the present invention provides can when each air-conditioner be in preset operating state, all the auxiliary device of air-conditioning internal machine is heated, so that the surface temperature of the auxiliary device of air-conditioning internal machine is more than the dew point temperature in the air channel of air-conditioning internal machine, so, after the compressor of air-conditioning reopens, the surface temperature of the auxiliary device of air-conditioning internal machine can always more than the dew point temperature in the air channel of air-conditioning internal machine, the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, thus avoiding the occurrence of the problem that air-conditioning blows water.
The method controlling air-conditioner that the embodiment of the present invention provides is when the running status of air-conditioner is preset operating state, control air-conditioner the auxiliary device of air-conditioning internal machine is heated, make the surface temperature of auxiliary device of air-conditioning internal machine more than the dew point temperature in the air channel of air-conditioning internal machine, so that after the compressor of air-conditioning is again turned on, the surface temperature of the auxiliary device of air-conditioning internal machine is more than the dew point temperature in the air channel of air-conditioning internal machine, the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, therefore would not cause that air-conditioning blows water, solve air-conditioning in prior art and blow the technical problem of water, achieve the air-conditioning dry tack free technique effect without the globule.
Alternatively, control air-conditioner to be heated including to the auxiliary device of air-conditioning internal machine: the surface temperature of the auxiliary device of detection air-conditioning internal machine; If be detected that the surface temperature of the auxiliary device of air-conditioning internal machine is less than or equal to dew point temperature, then controls air-conditioner and the auxiliary device of air-conditioning internal machine is heated.
When air-conditioner is in preset operating state, the surface temperature of the auxiliary device of detection air-conditioning internal machine. If be detected that the surface temperature of the auxiliary device of air-conditioning internal machine is more than dew point temperature, now, the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, is not result in air-conditioning and blows water, now, the auxiliary device of air-conditioning internal machine is not heated.
If be detected that the surface temperature of the auxiliary device of air-conditioning internal machine is less than or equal to dew point temperature, now, control air-conditioner the auxiliary device of air-conditioning internal machine is heated, make the surface temperature of auxiliary device of air-conditioning internal machine more than the dew point temperature in the air channel of air-conditioning internal machine, so, the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, thus not havinging the problem that air-conditioning blows water.
Due to when air-conditioner is in preset operating state, the surface temperature of the auxiliary device of air-conditioning internal machine likely can be higher than the dew point temperature in the air channel of air-conditioning internal machine, when the surface temperature of the auxiliary device of air-conditioning internal machine is higher than the dew point temperature in the air channel of air-conditioning internal machine, if still the auxiliary device of air-conditioning internal machine is heated, the energy can be wasted, and too high temperature is easily caused the auxiliary device generation abnormal flavour of air-conditioning internal machine.
The method controlling air-conditioner that the embodiment of the present invention provides is by when air-conditioner is in preset operating state, the surface temperature of the auxiliary device of detection air-conditioning internal machine, only when the surface temperature of the auxiliary device of air-conditioning internal machine is less than or equal to dew point temperature, just control air-conditioner the auxiliary device of air-conditioning internal machine is heated, avoid when the surface temperature of auxiliary device of air-conditioning internal machine is more than dew point temperature, the auxiliary device of air-conditioning internal machine is heated the energy waste caused.
Alternatively, after controlling air-conditioner and the auxiliary device of air-conditioning internal machine be heated, the method controlling air-conditioner that the embodiment of the present invention provides also includes: in the process that the auxiliary device of air-conditioning internal machine is heated, the surface temperature of the auxiliary device of detection air-conditioning internal machine; Judging that whether the surface temperature of auxiliary device of air-conditioning internal machine is be more than or equal to the first preset temperature, wherein, the first preset temperature is more than dew point temperature; If it is judged that the surface temperature of the auxiliary device of air-conditioning internal machine is be more than or equal to the first preset temperature, then controls air-conditioner and stop the auxiliary device of air-conditioning internal machine is heated.
In the process that the auxiliary device of air-conditioning internal machine is heated, the surface temperature of the auxiliary device of detection air-conditioning internal machine, when the surface temperature of auxiliary device of air-conditioning internal machine is be more than or equal to the first preset temperature, then controls air-conditioner and stop the auxiliary device of air-conditioning internal machine is heated. First preset temperature is a temperature more than dew point temperature, it is possible to be configured according to practical situation. When the surface temperature of auxiliary device of air-conditioning internal machine is be more than or equal to the first preset temperature, the surface temperature of the auxiliary device of air-conditioning internal machine is also greater than dew point temperature, the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, now, it is not necessary to continue the auxiliary device of air-conditioning internal machine is heated.
During by the surface temperature of the auxiliary device at air-conditioning internal machine be more than or equal to the first preset temperature, control air-conditioner to stop the auxiliary device of air-conditioning internal machine is heated, avoid and the auxiliary device of air-conditioning internal machine is heated the energy waste that extremely too high temperature causes, it also avoid the abnormal flavour heated by the auxiliary device of air-conditioning internal machine to too high temperature generation.
Alternatively, before the auxiliary device of air-conditioning internal machine is heated by control air-conditioner, the method controlling air-conditioner that the embodiment of the present invention provides also includes: the pressure in the air channel of detection air-conditioning internal machine; The corresponding relation of the dew point temperature in acquisition pressure and air channel; The dew point temperature corresponding to the pressure in the air channel of air-conditioning internal machine is determined according to corresponding relation.
Owing to dew point temperature is associated with pressure, when the pressure in the air channel of air-conditioning internal machine changes, the dew point temperature in the air channel of air-conditioning internal machine also can change. When air-conditioning is in different running statuses, the pressure in the air channel of air-conditioning internal machine is different, thus the dew point temperature in the air channel of air-conditioning internal machine is also different. By the pressure in the air channel of detection air-conditioning internal machine, determine the dew point temperature corresponding to the pressure in the air channel of air-conditioning internal machine according to the corresponding relation of the dew point temperature in pressure and air channel, reached accurately to determine the technique effect of the dew point temperature in air channel.
At the present embodiment, it is possible to determine dew point temperature according to the pressure in air channel so that the surface temperature of the auxiliary device of air-conditioning internal machine is higher than dew point temperature, namely the surface temperature of the auxiliary device of the air-conditioning internal machine after heating changes along with the difference of dew point temperature.The present embodiment can also make the surface temperature of the auxiliary device of the air-conditioning internal machine after heating be fixed temperature, the second preset temperature described as follows.
Alternatively, control air-conditioner to be heated including to the auxiliary device of air-conditioning internal machine: control air-conditioner and the surface temperature of the auxiliary device of air-conditioning internal machine is heated to the second preset temperature, wherein, second preset temperature is more than dew point temperature, and the second preset temperature is less than the first preset temperature, first preset temperature is set to indicate that air-conditioner is when the surface temperature of the auxiliary device of air-conditioning internal machine reaches the first preset temperature, stops the auxiliary device of air-conditioning internal machine is heated.
If it find that when the surface temperature of the auxiliary device of air-conditioning internal machine is less than or equal to dew point temperature, it is necessary to the auxiliary device of heating air-conditioning internal machine. Now, control air-conditioner and the surface temperature of the auxiliary device of air-conditioning internal machine is heated to the second preset temperature. Second preset temperature is more than dew point temperature, and the second preset temperature is less than the first preset temperature.
Owing to the second preset temperature is more than dew point temperature, therefore, after the surface temperature of the auxiliary device of air-conditioning internal machine is heated to the second preset temperature, the surface temperature of the auxiliary device of air-conditioning internal machine is necessarily greater than dew point temperature, the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, would not occur that air-conditioning blows the phenomenon of water yet.
Multiple local the first preset temperature occurred of the embodiment of the present invention is meant that identical, specifically, first preset temperature is such a temperature value: when the surface temperature of the auxiliary device of air-conditioning internal machine reaches the first preset temperature, stops the auxiliary device of air-conditioning internal machine is heated.
By controlling air-conditioner, the surface temperature of the auxiliary device of air-conditioning internal machine is heated to the second preset temperature more than dew point temperature, not only the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, avoid air-conditioning and blow the phenomenon of water, and, it is possible to accurately control the auxiliary device of air-conditioning internal machine is heated.
The method controlling air-conditioner that the embodiment of the present invention provides increases control program in the controller of air-conditioning, when air-conditioning is in preset operating state, the surface temperature of the auxiliary device of detection air-conditioning internal machine, when the surface temperature of auxiliary device of air-conditioning internal machine is less than or equal to dew point temperature, air-conditioner automatically turns on micro-heating operational mode, the auxiliary device of the air-conditioning internal machines such as heating heat-generating pipe, make the surface temperature of auxiliary device of the air-conditioning internal machines such as heat-generating pipe higher than the dew point temperature in air channel, thus after the compressor of air-conditioning is started working again, the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, avoid air-conditioning and blow the phenomenon of water.
According to embodiments of the present invention, a kind of device controlling air-conditioner is additionally provided. The device of this control air-conditioner can perform the method for above-mentioned control air-conditioner, and the method for above-mentioned control air-conditioner can also be implemented by the device of this control air-conditioner.
As in figure 2 it is shown, the device of this control air-conditioner includes the first detection unit the 22, first judging unit 24 and the first control unit 26.
First detection unit 22 is for detecting the running status of air-conditioner.
Whether the first judging unit 24 is preset operating state for judging the running status of air-conditioner, and wherein, preset operating state is that air-conditioner is in refrigerating operaton process, and running status when compressor quits work.
First control unit 26 is for when judging that the running status of air-conditioner is preset operating state, control air-conditioner the auxiliary device of air-conditioning internal machine is heated, so that the surface temperature of the auxiliary device of air-conditioning internal machine is more than the dew point temperature in the air channel of air-conditioning internal machine.
The auxiliary device of air-conditioning internal machine includes heat-generating pipe, etc.
When air-conditioner runs, if the surface temperature of the auxiliary device of air-conditioning internal machine is lower than the dew point temperature in the air channel of air-conditioning internal machine, the surface of the auxiliary device of air-conditioning internal machine there will be the globule of condensation, and these globules drip on the blower fan of air-conditioning, can cause that air-conditioning blows water. When air conditioner heat-production runs, the surface temperature of the auxiliary device of air-conditioning internal machine is higher, it will usually higher than the dew point temperature in the air channel of air-conditioning internal machine, now, and the surface of the auxiliary device of air-conditioning internal machine does not have the globule of condensation, is not result in air-conditioning and blows water. When air-conditioner refrigerating operaton, the surface temperature of the auxiliary device of air-conditioning internal machine is relatively low, it is possible to can lower than the dew point temperature in the air channel of air-conditioning internal machine. When the surface temperature of auxiliary device of air-conditioning internal machine is lower than dew point temperature in the air channel of air-conditioning internal machine, the surface of the auxiliary device of air-conditioning internal machine there will be the globule of condensation, and these globules drip on the blower fan of air-conditioning, can cause that air-conditioning blows water.
After the operational mode of user setup air-conditioner is refrigerating operaton, the compressor of air-conditioning opens (namely starting working), indoor temperature declines, after indoor temperature drops to the first preset value (the first preset value be the target temperature value of user setup or slightly below the temperature value of target temperature value of user setup), the compressor of air-conditioning quits work (being in holding state), hereafter, indoor temperature rises, after indoor temperature rises to the second preset value (the second preset value is a temperature value more than the first preset value), the compressor of air-conditioning is started working again, indoor temperature declines. preset operating state in the embodiment of the present invention refers to that air-conditioner is in refrigerating operaton process, and running status when compressor quits work. in general, air-conditioner has in refrigerating operaton process and is repeatedly in preset operating state, and the time that air-conditioning is repeatedly in preset operating state is the discontinuous time period.
Such as, when 10:00, indoor temperature is 30 DEG C, now user uses the operational mode that remote controller arranges air-conditioner to be refrigerating operaton and to arrange target temperature be 22 DEG C, the compressor of air-conditioning is opened, and indoor temperature declines, when 10:30 indoor temperature drops to 21 DEG C, the compressor of air-conditioning quits work, hereafter, indoor temperature is slowly gone up, when 10:35 indoor temperature is 23 DEG C, the compressor of air-conditioning is started working again, and indoor temperature declines. When 10:37 indoor temperature drops to 21 DEG C, the compressor of air-conditioning quits work, and when 10:43 indoor temperature is 23 DEG C, the compressor of air-conditioning is started working again. In this example, air-conditioning is in refrigerating operaton process at 10:00-10:43, and the time period that the running status of air-conditioner is preset operating state has two, is 10:30-10:35 and 10:37-10:43 respectively.
