Step 104: when executing the first inletting fresh air control process, acquisition outdoor environment temperature and indoor carbon dioxide are dense first Degree, and make comparisons respectively with default outer circumstance temperature condition and setting concentration.
Outdoor environment temperature can be got by the temperature sensor being arranged on air-conditioner outdoor unit, indoor titanium dioxide Concentration of carbon can by be arranged carbon dioxide concentration detecting device indoors, such as be arranged on air-conditioner indoor unit shell two Carbonoxide concentration sensor is got.
Then, the outdoor environment temperature that will acquire is made comparisons with default outer circumstance temperature condition, the indoor titanium dioxide that will acquire Concentration of carbon is made comparisons with setting concentration, and is determined whether to open or close fresh air ventilating system according to comparison result.Wherein, it presets outer Circumstance temperature condition be reflect outdoor environment temperature whether be preference temperature condition, setting concentration be reflection indoor carbon dioxide concentration The concentration value of height, default outer circumstance temperature condition and setting concentration preset and store, and control unit above-mentioned can facilitate Ground is read.
As preferred embodiment, default outer circumstance temperature condition includes: air conditioner operation refrigeration mode, outdoor environment temperature Greater than the first set temperature;Alternatively, air conditioner runs heating mode, outdoor environment temperature is less than the second set temperature.Wherein, One set temperature is preferably 28 DEG C, and the second set temperature is preferably 22 DEG C.
For set concentration, include in this embodiment there are two, respectively first setting concentration and second setting concentration, And first sets concentration greater than the second setting concentration.
Default outer circumstance temperature condition and concrete meaning and the effect for setting concentration, please refer to subsequent description.
Step 105: judging whether indoor carbon dioxide concentration is greater than the first setting concentration.If so, executing step 106;It is no Then, step 104 is gone to, continues to judge.
Step 106: if indoor carbon dioxide concentration is greater than the first setting concentration, opening fresh air ventilating system.Then, it holds Row step 107.
By reasonable selection first set concentration so that first set concentration be gas concentration lwevel it is exceeded, reflect interior One concentration value of differential air.If indoor carbon dioxide concentration is greater than the first setting concentration, it is necessary to inletting fresh air is opened, it will be outer The Leads to new breeze in portion to interior.That is, in this case, regardless of outdoor environment temperature, equal enforced opening fresh air ventilating system Carry out inletting fresh air.Wherein, fresh air ventilating system can be a system being independently arranged, and be also possible to be formed in changing on air conditioner Fresh air system, the embodiment are not construed as limiting this.
Since air conditioner is in running order at this time namely user opens air conditioner and carries out refrigeration adjusting to room air Or heating is adjusted, and shows that outdoor temperature is not comfort temperature at this time.If opening inletting fresh air, it will outdoor temperature is unfavorable Leads to new breeze is to interior, so that room temperature comfort declines.Therefore, the embodiment in the case where air conditioner is in running order, open After opening fresh air ventilating system, need to judge parameter using outdoor environment temperature and indoor carbon dioxide concentration as two, to control When fresh air ventilating system is closed.It specifically, is the process for executing step 107.
Step 107: after step 106 opens fresh air ventilating system, continuing to outdoor environment temperature and indoor carbon dioxide Concentration is detected in real time, and is made comparisons respectively with default outer circumstance temperature condition and setting concentration.If meeting following two condition In any condition, then to close fresh air ventilating system:
First condition: gas concentration lwevel is greater than the second setting concentration but no more than the first setting concentration and outdoor ring Border temperature, which meets, presets outer circumstance temperature condition;
Second condition: outdoor environment temperature does not meet default outer circumstance temperature condition and indoor carbon dioxide concentration is not more than The condition of second setting concentration.
Such as preceding recorded for first condition, default outer circumstance temperature condition is whether reflection outdoor environment temperature is suitable The condition of temperature.For example, presetting outer circumstance temperature condition are as follows: air conditioner runs refrigeration mode, and outdoor environment temperature is greater than the first setting Temperature, such as larger than 28 DEG C.Air conditioner runs refrigeration mode, shows that room temperature is higher, needing to reduce room temperature could obtain Comfortable temperature environment.If outdoor environment temperature is greater than 28 DEG C at this time, after opening inletting fresh air, the Leads to new breeze of outdoor high temperature To interior, will certainly room temperature be increased, not only make room temperature uncomfortable, and can make air conditioner that high frequency be wanted to transport Turn, increases air conditioner energy consumption.Therefore, if outdoor environment temperature, which meets, presets outer circumstance temperature condition, as long as gas concentration lwevel Between the second setting concentration and the first setting concentration, fresh air ventilating system will be forcibly closed.Wherein, the second setting concentration is less than First setting concentration is that gas concentration lwevel is moderate, room air is a good concentration value for reflection.That is, if air conditioner After refrigerating operaton, unlatching fresh air ventilating system, if outdoor environment temperature is not suitable for, when indoor carbon dioxide concentration is reduced to sky In the case that makings amount is good, it is shut off inletting fresh air, reduces because inletting fresh air causes room temperature to be not suitable for, air conditioner energy consumption is excessively high The problems such as bring influence.
Same mechanism, if presetting outer circumstance temperature condition are as follows: air conditioner operation heating mode, outdoor environment temperature is less than the Two set temperatures, such as less than 22 DEG C, show that room temperature is too low, and comfortable temperature ring could be obtained by needing to increase room temperature Border.If outdoor environment temperature is less than 22 DEG C at this time, after opening inletting fresh air, the Leads to new breeze of outdoor low temperature is bound to interior Meeting not only makes room temperature uncomfortable, and air conditioner can be made to operate in a high frequency, increases air-conditioning so that room temperature decline Device energy consumption.Therefore, if outdoor environment temperature, which meets, presets outer circumstance temperature condition, as long as gas concentration lwevel is dense positioned at the second setting Between degree and the first setting concentration, it is also desirable to forcibly close fresh air ventilating system.
Current outdoor environment is shown if outdoor environment temperature, which is not met, presets outer circumstance temperature condition for second condition Temperature and indoor environment temperature difference are not too greatly, the significant changes of room temperature will not to be caused after introducing outdoor air.This feelings Under condition, then extend inletting fresh air runing time, accelerate indoor inletting fresh air, until indoor carbon dioxide concentration sets concentration down to second And hereinafter, to improve indoor air quality.
Inletting fresh air is controlled using the method for above-described embodiment, according to the refrigeration of air conditioner or heating working condition, The control fresh air ventilating systems starting of three conditions of outdoor environment temperature and indoor carbon dioxide concentration is closed, by indoor titanium dioxide While concentration of carbon control is in reasonable range, reduces the unfavorable fresh air of outdoor temperature and be introduced in interior, it is not only simultaneous Indoor carbon dioxide concentration and Thermal comfort have been cared for, the comfort of indoor environment is improved, moreover it is possible to the energy consumption of air conditioner is reduced, Realize energy saving purpose.
Fig. 2 is referred to, the figure shows the flow charts of second embodiment of inletting fresh air control method of the present invention.
As shown in Fig. 2, the method that the embodiment realizes inletting fresh air control includes the following steps:
Step 201: judging that indoor air conditioner is in running order or off-mode.
Step 202: if air conditioner is in running order, executing the first inletting fresh air control process.
Step 201 and step 202 more specifically describe, referring to Figure 1 the corresponding steps of embodiment.
Step 203: if air conditioner is in off-mode, executing the second inletting fresh air control process.
Step 204: when executing the first inletting fresh air control process, acquisition indoor environment temperature and indoor carbon dioxide are dense first Degree, and make comparisons respectively with default interior circumstance temperature condition and setting concentration.
Indoor environment temperature can be got by the way that temperature sensor indoors is arranged, and indoor carbon dioxide concentration can be with By the way that carbon dioxide concentration detecting device indoors is arranged, gas concentration lwevel on air-conditioner indoor unit shell is such as arranged in Sensor is got.Moreover, indoor environment temperature and indoor carbon dioxide concentration remain to obtain air conditioner is in shutdown state It gets.
Then, the indoor environment temperature that will acquire is made comparisons with default interior circumstance temperature condition, the indoor titanium dioxide that will acquire Concentration of carbon is made comparisons with setting concentration, and is determined whether to open or close fresh air ventilating system according to comparison result.Wherein, in presetting Circumstance temperature condition be reflect indoor environment temperature whether be preference temperature condition, setting concentration be reflection indoor carbon dioxide concentration The concentration value of height, default interior circumstance temperature condition and setting concentration preset and store, and control unit above-mentioned can facilitate Ground is read.
As preferred embodiment, default interior circumstance temperature condition includes: that indoor environment temperature is greater than third set temperature;Or Person, indoor environment temperature is less than the 4th set temperature.Wherein, third set temperature is preferably 27 DEG C, is slightly less than Fig. 1 embodiment First set temperature;4th set temperature is preferably 23 DEG C, slightly larger than the second set temperature of Fig. 1 embodiment.
It is similar with the first inletting fresh air control process in Fig. 1 embodiment for setting concentration.
Step 205: judging whether indoor carbon dioxide concentration is greater than the first setting concentration.If so, executing step 206 and step Rapid 208;Otherwise, step 204 is gone to, continues to judge.
As described by Fig. 1 embodiment, first set concentration as gas concentration lwevel it is exceeded, reflection room air difference one Concentration value.In this embodiment, if indoor carbon dioxide concentration is greater than the first setting concentration, in addition to executing step 206 and step Rapid 207 inletting fresh air treatment process is also performed simultaneously the alert process process of step 208 and step 209.Detailed process is under The description of each step in face.
Step 206: if indoor carbon dioxide concentration is greater than the first setting concentration, opening fresh air ventilating system.Then, it holds Row step 207.
Under air conditioner off-mode, if indoor carbon dioxide concentration is greater than the first setting concentration, it is necessary to which unlatching is changed Fresh air, by external Leads to new breeze to interior.That is, in this case, regardless of indoor environment temperature, equal enforced opening is changed Fresh air system carries out inletting fresh air.
Step 207: after step 206 opens fresh air ventilating system, continuing to indoor environment temperature and indoor carbon dioxide Concentration is detected in real time, and is made comparisons respectively with default interior circumstance temperature condition and setting concentration.If meeting following two condition In any condition, then to close fresh air ventilating system:
First condition: gas concentration lwevel is greater than the second setting concentration but no more than the first setting concentration and indoor ring Border temperature meets circumstance temperature condition in default;
Second condition: indoor environment temperature does not meet in default circumstance temperature condition and indoor carbon dioxide concentration is less than the The condition of three setting concentration.Wherein, third setting concentration is less than the second setting concentration in Fig. 1 embodiment.By reasonable selection, So that third set concentration as gas concentration lwevel it is very low, reflection indoor air quality be an excellent concentration value.
Such as preceding recorded for first condition, default interior circumstance temperature condition is whether reflection indoor environment temperature is suitable The condition of temperature.For example, circumstance temperature condition in default are as follows: indoor environment temperature is greater than third set temperature, and such as larger than 27 DEG C.Due to Indoor environment temperature is higher at this time, then outdoor environment temperature can be higher, and after opening inletting fresh air, the Leads to new breeze of outdoor high temperature is arrived Interior will certainly make room temperature increase, so that room temperature is uncomfortable.Therefore, if indoor environment temperature meet it is default Outer circumstance temperature condition renews positive closing as long as gas concentration lwevel is located between the second setting concentration and the first setting concentration Wind system.Wherein, as recorded in Fig. 1 embodiment, the second setting concentration is reflection gas concentration lwevel less than the first setting concentration Moderate, room air is a good concentration value.That is, if air conditioner shuts down, after unlatching fresh air ventilating system, if indoor Environment temperature is not suitable for, and in the case that indoor carbon dioxide concentration is reduced to air quality to be good, is shut off inletting fresh air, reduces Because inletting fresh air leads to the more unfavorable influence of room temperature.
Same mechanism, if circumstance temperature condition in default are as follows: indoor environment temperature is less than the 4th set temperature, such as less than 23 DEG C, room temperature is lower.Since indoor environment temperature is lower at this time, then outdoor environment temperature can be lower.After opening inletting fresh air, The Leads to new breeze of outdoor low temperature will certainly make room temperature decline, so that room temperature is uncomfortable to interior.Therefore, if Indoor environment temperature meets circumstance temperature condition in default, as long as gas concentration lwevel is located at the second setting concentration and the first setting concentration Between, it is also desirable to forcibly close fresh air ventilating system.
Current indoor environment is shown if indoor environment temperature, which is not met, presets outer circumstance temperature condition for second condition Temperature is pleasant, and indoor environment temperature and outdoor environment temperature difference are not that very greatly, will not cause after introducing outdoor air The significant changes of room temperature.In this case, then extending inletting fresh air runing time, accelerate indoor inletting fresh air, until indoor dioxy Change concentration of carbon down to third setting concentration and hereinafter, to improve indoor air quality.
In second embodiment, if air conditioner is in off-mode, room temperature is not conditioned, room temperature It is little with outdoor temperature difference, then directly use indoor environment temperature as it is determined whether to enable or close fresh air ventilating system ginseng Number controls more accurate.
When step 205 determines that indoor carbon dioxide concentration is greater than the first setting concentration, it is also performed simultaneously following steps Alert process process.Specifically:
Step 208: control indoor alarm equipment issues alarm signal.
For example, being prompted indoor by the alarm signal of the sendings sound such as indoor sounding alarm, light-emitting alarm and/or light User's indoor carbon dioxide concentration is higher, is taken precautions against and is handled in time.
Step 209: when receiving closing indoor alarm equipment signal, control indoor alarm equipment stops issuing alarm signal; If not received in the setting time after the alarm signal of machine alarm sending indoors and closing indoor alarm equipment signal, in control room Wireless telecommunications system sends out alarm signal.
In this embodiment, it is provided with the device for closing indoor alarm equipment, user, can be with after receiving alarm signal The signal of closing indoor alarm equipment is issued to close indoor alarm equipment by the device, avoids alarm from generating noise to user dry It disturbs.Moreover, the device of the closing indoor alarm equipment is preferably provided with indoors.Therefore, indoor alarm equipment letter is closed if received Number, show user indoors, and the exceeded signal of gas concentration lwevel has been received, can be taken precautions against and be handled in time, Indoor alarm equipment is then controlled to stop issuing alarm signal.
But if user not indoors or user is in sleep state without perceiving alarm signal, Huo Zheyong Family is in the situations such as handicapped, expiratory dyspnea and can not be taken precautions against and be handled, may be because that cannot handle titanium dioxide in time The excessively high problem of concentration of carbon and accident occurs.To solve this problem, which is previously stored with setting time, for example, when setting Between be 5min, if indoor unit alarm issue alarm signal after setting time in do not receive close indoor alarm equipment letter Number, then it controls indoor wireless communication equipment and sends out alarm signal.Alarm signal is sent out, can be and specify to user Phone number issues, and is also possible to the department's sending that can sue and labour to First aid station, property center etc..Pass through indoor wireless communication equipment The specific implementation of signal is sent out, can be realized using the prior art.
