Here, the trust running is described.Entrust running by described trust switch 22 operations,, also pass through CO except control the existing running of air-conditioning ability according to the difference of room temperature and operating temperature
2Thereby sensor is held people's activity situation the air-conditioning ability is controlled running.The variation characteristic of the concentration of indoor carbon dioxide, as shown in Figure 5, according to 1) people is in indoor and movable situation, 2) situation and 3 of sleeping) and the people not situation, and differ widely, entrusting turns round utilizes this characteristic and divides into three stages (activity pattern, sleep pattern, unmanned pattern).
1) under the situation of activity, the concentration ratio of carbon dioxide is not being set concentration F height, and its amplitude of fluctuation H is big, judges setting value Hh more than or equal to sleep.
2) under the situation of sleep, the concentration ratio of carbon dioxide is not being set concentration F height, and its amplitude of fluctuation Hs is littler than amplitude of fluctuation Hk, judges setting value Hh less than sleep.In addition, sleep judges that setting value Hh is set to the value between the value of amplitude of fluctuation Hs of density of carbon dioxide gas of the value of amplitude of fluctuation Hk of the density of carbon dioxide gas in the activity and sleep.
3) people not situation under, the concentration ratio of carbon dioxide is not in that to set concentration F low, and its amplitude of fluctuation is small, judges that than above-mentioned amplitude of fluctuation Hk, Hs and sleep setting value Hh is little.
Thereby density of carbon dioxide gas does not exist than then not being judged to be when setting concentration F is low than then not being judged to be indoor when setting concentration F is high.And the amplitude of fluctuation of the concentration of carbon dioxide that can be in indoor is in the activity more than or equal to then judging when judging setting value Hh as the sleep of sleep determinating reference, then judges when judging setting value Hh less than sleep to be in sleep.
And, 1) entrust when operating as activity pattern, carry out as the common operation of air conditioner of design temperature roughly (below, be " normal operation ").
2) when trust operates as sleep pattern, carry out the sleep pattern running, when warming operation, reduce design temperature (for example about 1 ℃), and when cooling operation, improve design temperature (for example about 2～3 ℃), reduce the output of aircondition than running well.
Carry out unmanned mode operation when 3) entrusting running to be in unmanned pattern, when warming operation, reduce design temperature (for example about 2 ℃), and when cooling operation, improve design temperature (for example about 4～6 ℃), than the output (stopping used for indoor machine pressure fan 12 as required) of normal operation and sleep pattern running reduction aircondition.
Then, thus press the running flow process of the aircondition when entrusting switch 22g to entrust running according to the flowchart text of Fig. 6.
In step 1, CO
2Sensor 16 detects the concentration of carbon dioxide in room, and this detected value is sent to microcomputer 17, proceeds to step 2.In step 2, microcomputer 17 judges whether aircondition is in the running, is in when shutting down, and returns step 1 and waits for, and when being in the running, proceed to step 3.
In step 3, microcomputer 17 judges whether indication (that is, entrusting switch 22g to be pressed) trust running, under the situation that does not have indication, returns step 1, waits for and entrusts switch 22g to be pressed.On the other hand, under the situation of having indicated the trust running, enter and entrust running, and proceed to step 4.
In step 4, microcomputer 17 judges that conduct is from CO in step 1
2Whether the concentration of the carbon dioxide of the detected value of sensor 16 input is not less than or equal to is being set concentration F, proceeds to step 5 not being less than or equal under the situation of not setting concentration F, and proceeds to step 8 surpassing under the situation of not setting concentration F.
Then, in step 5, in order to prevent CO
2The situation continued at design temperature F is confirmed to be less than or equal to not in the misoperation that detection mistake, noise signal or the interference etc. of sensor 16 cause, and during predetermined fiducial time (for example, about 5 minutes).Under situation about can't confirm, the operation mode of maintaining the statusquo and return step 1.And, under identifiable situation, proceed to step 6.In step 6, microcomputer 17 is not judged to be and exists, and proceeds to step 7, and microcomputer 17 carries out unmanned mode operation.
And, in step 4,, as previously mentioned, proceed to step 8 surpassing not under the situation of design temperature F.Then, in step 8, microcomputer 17 according in the step 1 from CO
2The detected value of sensor 16 input ask carbon dioxide concentration amplitude of fluctuation (for example, following peak value and upward peak poor), and judge whether this amplitude of fluctuation judges setting value Hh more than or equal to sleep, more than or equal to situation under proceed to step 9, and under the situation of judging setting value Hh less than sleep, proceed to step 11.
In step 9, in order to prevent CO
2The misoperation that detection mistake, noise signal or the interference etc. of sensor 16 cause, and during fiducial time, confirm concentration surpass not set concentration F simultaneously concentration amplitude of fluctuation approximately or equal to sleep and judge the situation continued of setting value Hh.Under situation about can't confirm, the operation mode of maintaining the statusquo and return step 1.And, under identifiable situation, proceed to step 10.In step 10, microcomputer 17 judgements are in the activity indoor simultaneously for the people, norm formula (activity pattern) running that works of going forward side by side.
And, in step 8, judge under the situation of setting value Hh less than sleep in the amplitude of fluctuation of gas concentration lwevel, as previously mentioned, proceed to step 11, in step 11, in order to prevent CO
2The misoperation that detection mistake, noise signal or the interference etc. of sensor 16 cause, and during fiducial time, confirm that concentration surpasses the situation continued of not judging setting value Hh in the amplitude of fluctuation of setting concentration F while concentration less than sleep.Under situation about can't confirm, the operation mode of maintaining the statusquo and return step 1.And, under identifiable situation, proceed to step 12.In step 12, microcomputer 17 judges that behaviour is in sleep, and carries out the sleep pattern running.
Like this, based on CO
2Whether the concentration of the detected indoor carbon dioxide of sensor 16 judges the people indoor, not under the situation, the running of aircondition is made as unmanned mode operation, reduces its output than running well.Thereby,, also can do one's utmost to prevent to carry out useless air and be in harmonious proportion although not indoor.
And, based on CO
2The concentration of the detected indoor carbon dioxide of sensor 16 judges whether the people is in the activity, under the situation of sleep, the running of aircondition is made as sleep pattern, reduces its output than running well.Therefore, the air-supply sound of used for indoor machine pressure fan 12 reduces, and can prevent owing to the air-supply sound hinders sleep.And, refrigeration in the time of can preventing to sleep or heating excessive.Its result can cosily sleep.
Then, the flow chart based on Fig. 7 illustrates based on CO
2The flow process of the strick precaution that the detected value of sensor 16 carries out.
When being made as the safe handling of taking precautions against usefulness when going out etc., no matter shut down in the running of aircondition, the safety switch 22h of remote controller 4, thus the instruction of safe handling is sent via microcomputer 24 from sending part 23.So the receiving portion 14 of indoor set 3 receives, the instruction of safe handling is imported into microcomputer 17, carries out safe handling.The releasing of running is installed to be undertaken by the safety switch 22h of remote controller 4 too.
Then, in step 21, CO
2Sensor 16 detects the concentration of the carbon dioxide in room, and its detected value is sent to microcomputer 17, proceeds to step 22.In step 22, microcomputer 17 judges whether to be the safe handling pattern, return step 21 under the situation that is not the safe handling pattern.On the other hand, under the situation of safe handling, proceed to step 23.
In step 23, microcomputer according in step 21 from CO
2The detected value of sensor 16 inputs is asked the change value of the concentration of carbon dioxide, and judges that whether this amplitude of fluctuation is more than or equal to invading decision content (under the situation of this embodiment, for judging the identical value of setting value Hh with sleep) Hh.Then, under the situation of judging setting value Hh less than sleep, return step 21 and maintain the statusquo.On the other hand, under the situation of judging setting value Hh more than or equal to sleep, proceed to step 24.
In step 24, microcomputer 17 is in order to prevent CO
2The misoperation that detection mistake, noise signal or the interference etc. of sensor 16 cause, and during predetermined fiducial time (for example, about 5 minutes), confirm that the amplitude of fluctuation of density of carbon dioxide gas is judged the situation continued that sets value Hh more than or equal to sleep.Then, under the situation that does not have continuation, return step 21, and maintain the statusquo.On the other hand, under situation about continuing, proceed to step 25, judging has the people to invade, and proceeds to step 26.In step 26, microcomputer 17 makes the siren action, and returns step 26.This alarm device 13 comprises the alarm device that produces alarm tone, with the emergency communicator of contact such as mobile phone or produce the emergency warning lamp etc. of light etc.
Like this, when safe handling, the amplitude of fluctuation of the concentration of carbon dioxide can judge that the someone invades during greater than setting, and makes alarm device 13 actions.
Like this, control assembly comprises: 1) unmanned judging part, and based on CO
2The detected detected value of sensor is judged the people indoor or do not exist, be judged to be not situation under, aircondition is made as unmanned mode operation, 2) the sleep judging part, based on CO
2The detected detected value of sensor is judged to be in the activity or sleep, being judged to be under the situation of sleep, aircondition is made as sleep pattern, 3) invade judging part, when being set at safe handling, based on described CO
