Detailed Description
< integral Structure >
Fig. 1 is a block diagram showing an overall structure of an intelligent air conditioning system of the present invention.
As shown in fig. 1, an intelligent air conditioning system 1 of the present invention includes an air conditioner 20, an air cleaner 30, a fresh air fan 40, and a control unit 10.
The air conditioner 20 can adjust parameters such as temperature and humidity of the indoor ambient air and can supply air to the room. The air conditioner 20 may be a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling air conditioner, or the like, and is not particularly limited.
In the present embodiment, the air conditioner 20 is controlled by the control unit 10 so as to trigger the dust removal process according to the dust concentration.
The air purifier 30 can adsorb, decompose or convert various air pollutants (generally including PM2.5, decoration pollution such as pollen and formaldehyde, bacteria, etc.), and effectively improve the air cleanliness. The air purifier 30 may employ an adsorption technique, a negative (positive) ion technique, a catalytic technique, a photocatalyst technique, a superstructure photo-mineralization technique, a HEPA high-efficiency filtration technique, an electrostatic precipitation technique, and the like, without particular limitation.
Further, in the present embodiment, the air cleaner 30 is controlled by the control portion 10 so as to be triggered to perform the dust removing process according to the dust concentration and to perform the offensive odor removing process according to the degree of offensive odor.
The fresh air blower 40 circulates indoor air, discharges dirty indoor air to the outside, and simultaneously inputs fresh outdoor air to the inside of the room after sterilization, disinfection, filtration, and other measures, thereby performing indoor air replacement.
Further, in the present embodiment, the fresh air fan 40 is controlled by the control section 10 so as to be triggered to perform the ventilation processing according to the carbon dioxide concentration and to perform the offensive odor removal processing according to the degree of offensive odor.
The control unit 10 determines whether or not to continue any of the foreign odor removal processing, the ventilation processing, and the dust removal processing, based on a unit abnormality occurring in at least one of the air conditioner 20, the air cleaner 30, and the fresh air blower 40, or a user operation.
Next, the control of the air conditioner 20, the air cleaner 30, and the fresh air fan 40 by the control unit 10 will be described in detail.
< abnormal conditions of the unit during the process of removing the offensive odor >
Fig. 2 is a schematic diagram illustrating a case where an abnormality occurs in a unit during an offensive odor removal process in the intelligent air conditioning system of the present invention.
The control unit 10 determines whether or not to perform the foreign odor removal process based on the degree of foreign odor. When it is determined that the degree of the offensive odor is equal to or greater than the predetermined first threshold value, the control unit 10 starts (triggers) the offensive odor removal process, that is, performs control such that the air cleaner is started and the fresh air fan is operated in the full heat exchange mode high-speed range.
Further, there are four possibilities of the states (on-trigger states) of the air cleaner and the fresh air blower at the start (on-trigger) of the foreign odor removal process: the air purifier is started and the fresh air machine is started; the air purifier is started and the fresh air machine is closed; the air purifier is closed and the fresh air fan is opened; the air purifier is closed and the fresh air machine is closed.
Further, the odor removal processing is the highest priority, and the odor removal processing action is preferentially triggered in any case.
In the process of performing the foreign odor removal processing, when the unit abnormality that connection is lost or an error is reported to stop occurs in the air cleaner 30 or the new fan 40, the foreign odor removal processing (i.e., opening) is continued, when the unit abnormality that connection is lost occurs in the air cleaner 30 or the new fan 40, the foreign odor removal processing (i.e., opening) is continued, and when the unit abnormality that the error is reported to stop occurs in the air cleaner 30 or the new fan 40, the foreign odor removal processing is ended (i.e., returned) and the state at the time of triggering is returned.
When the foreign odor removal processing is continued, if the degree of the detected foreign odor is less than a predetermined first threshold value (the termination condition is satisfied), the foreign odor removal processing is terminated and the state is returned to the trigger state.
However, in the foreign odor removal process, if a user operates a certain device, the device is terminated based on the final operation of the user, and the remaining devices (if any) return to the triggered state.
For example, if the state at the time of triggering is the state in which the air cleaner is on and the new air blower is on, but if the user manually turns off the air cleaner after the trigger linkage, that is, during the process of removing the offensive odor, even if it is determined that the offensive odor removal process is continued (that is, the state is on), the air cleaner remains off after the end condition is satisfied, and only the new air blower returns to the state at the time of triggering, that is, the state is on.
Therefore, the intelligent air conditioner can be in a state of meeting the requirements of the user, and the distrust feeling of the user due to excessive intelligent control is avoided.
< situation of occurrence of unit abnormality in process of ventilation treatment >
Fig. 3 is a schematic diagram illustrating a case where a unit abnormality occurs during an air exchange process in the intelligent air conditioning system of the present invention.
The control unit 10 determines whether or not to perform ventilation processing based on the concentration of carbon dioxide. When determining that the concentration of carbon dioxide is equal to or higher than a predetermined second threshold value (1000 pm in the present example), the control unit 10 starts (triggers) the ventilation process, that is, controls the fresh air fan to operate at the high-speed stage in the total heat exchange mode.
Further, there are three possibilities of the state of the fresh air machine at the start (trigger) of the ventilation process (trigger state): the fresh air fan runs at a high gear; the new fan runs at a low gear; and (5) closing the fresh air machine.
In addition, the ventilation process is of the second priority, and if the action of higher priority (i.e., the odor removal process) is performed, the ventilation process is triggered after waiting for the completion of the action.
In the process of performing the ventilation processing, the ventilation processing is continued when the unit abnormality that the connection of the new fan 40 is lost occurs, and the ventilation processing is ended and the state at the time of triggering is returned when the unit abnormality that the error report is stopped occurs in the new fan 40.
When the ventilation process is continued, if the detected carbon dioxide concentration is less than the predetermined second threshold, the ventilation process is terminated.
Generally speaking, when the concentration of carbon dioxide is 350-450 ppm, the carbon dioxide is perceived as a common outdoor environment; when the concentration of the carbon dioxide is 350-1000 ppm, people feel fresh air and breathe smoothly; when the concentration of carbon dioxide is 1000-2000 ppm, people feel turbid air and drowsy.
In this example, the second threshold value was set to 500 ppm. In addition, the second threshold is not limited to 500pm, and may be appropriately set with reference to the carbon dioxide concentration and the physiological reaction of the human body.
In addition, similarly to the foreign odor removal process, if a user operates a certain device in the ventilation process, the device is terminated based on the final operation of the user, and the remaining devices (if any) return to the triggered state.
Therefore, the intelligent air conditioner can be in a state of meeting the requirements of the user, and the distrust feeling of the user due to excessive intelligent control is avoided.
< case of unit abnormality occurring in the process of dust removal processing >
Fig. 4 is a schematic diagram illustrating a case where a unit abnormality occurs during a dust removal process in the intelligent air conditioning system of the present invention.
In the present embodiment, the control unit 10 determines whether the pollution is mild or moderate based on the concentration of PM2.5, that is, the concentration of PM2.5 is 75 to 115 μ g/m3When the concentration of PM2.5 is not less than 115 μ g/m, the pollution is judged to be light pollution3Moderate contamination was judged.
When it is determined that the air cleaner is lightly contaminated, the control unit 10 starts (triggers) the dust removal process in the light contamination mode, that is, controls the air cleaner 30 to be started and the fresh air fan 40 to be stopped.
Further, there are four possibilities of the states (states at the time of activation) of the air cleaner and the fresh air blower at the time of start (activation) of the dust removal process in the light pollution mode: the air purifier is started and the fresh air machine is started; the air purifier is started and the fresh air machine is closed; the air purifier is closed and the fresh air fan is opened; the air purifier is closed and the fresh air machine is closed.
In addition, the dust removal process in the light pollution mode is the third priority, and if the higher priority level (i.e., the odor removal process and the ventilation process) is used, the dust removal process is triggered after waiting for the completion of the operation.
In the dust removal processing in the light pollution mode, when a unit abnormality that connection is lost occurs in the air cleaner 30 or the fresh air fan 40, the dust removal processing in the light pollution mode is continued, when a unit abnormality that an error report is stopped occurs in the fresh air fan 40, the dust removal processing in the light pollution mode is continued, and when a unit abnormality that an error report is stopped occurs in the air cleaner 30, the dust removal processing in the light pollution mode is ended and the state at the time of triggering is returned.
When the dust removal process in the light pollution mode is continued, if the dust concentration is equal to or less than a predetermined third threshold value or the middle pollution mode is triggered, the dust removal process in the light pollution mode is terminated and the state is returned to the triggered state.
Regarding the third threshold value, in order to avoid frequent start-stop of the apparatus, it may be set appropriately after actual evaluation. In this embodiment, the third threshold is set to 50 μ g/m3But is not limited thereto.
Further, similarly to the foreign odor removal process, in the dust removal process in the light pollution mode, if a user operates a certain apparatus, the end operation of the apparatus is based on the final operation of the user, and the remaining apparatuses (if any) return to the state at the time of activation.
For example, in the case of light pollution, it is assumed that the air cleaner is on and the fresh air fan is on when triggered, but if the user manually turns off the air cleaner after the trigger linkage, that is, during the dust removal process, the air cleaner remains off even after the dust removal process (i.e., return) is determined to be completed, and only the fresh air fan returns to the state when triggered, that is, is turned on.
Therefore, the intelligent air conditioner can be in a state of meeting the requirements of the user, and the distrust feeling of the user due to excessive intelligent control is avoided.
When it is determined that the pollution is moderate, the control unit 10 starts (triggers) the dust removal process in the moderate pollution mode, that is, controls the air conditioner 20 to perform the air blowing operation, starts the air cleaner 30, and turns off the fresh air fan 40.
In addition, there are several possibilities of the states (on-trigger states) of the air conditioner, the air cleaner, and the fresh air machine at the start (on-trigger) of the dust removal process in the moderate pollution mode: the air conditioner carries out four possibilities under the mode of humidity/cold air/warm air operation + light pollution; the air conditioner has four possibilities of air supply operation/closing and light pollution modes.
In addition, the dust removing process in the middle pollution mode is the third priority, and if the higher priority level (i.e., the odor removing process and the ventilation process) is required, the dust removing process is triggered after waiting for the completion of the operation.
In the process of dust removal processing in the moderate pollution mode, when a unit abnormality occurs in the air conditioner 20, the air purifier 30 or the fresh air fan 40, the connection of which is lost, the dust removal processing in the moderate pollution mode is continued, when a unit abnormality occurs in the air conditioner 20 or the fresh air fan 40, the error-reporting stop of which is stopped, the dust removal processing in the moderate pollution mode is continued, and when a unit abnormality occurs in the air purifier 30, the error-reporting stop of which is stopped, the dust removal processing in the moderate pollution mode is ended and the state at the time of triggering is returned.
When the dust removal process in the moderate pollution mode is continued, if the dust concentration is equal to or lower than the predetermined fourth threshold and the light pollution mode is triggered, the dust removal process in the moderate pollution mode is ended and the state is returned to the triggered state.
Regarding the fourth threshold value, in the present embodiment, the fourth threshold value is set to 100 μ g/m3However, the present invention is not limited to this, and may be appropriately set after actual evaluation.
Further, similarly to the odor removal process, in the dust removal process in the middle pollution mode, if a user operates a certain apparatus, the end operation of the apparatus is based on the final operation of the user, and the remaining apparatuses (if any) return to the state at the time of activation.
Therefore, the intelligent air conditioner can be in a state of meeting the requirements of the user, and the distrust feeling of the user due to excessive intelligent control is avoided.
By configuring the intelligent air conditioning system 1 including the air conditioner 20, the air cleaner 30, the fresh air fan 40, and the control unit 10 according to the present invention as described above, it is possible to prevent a system error from occurring in the intelligent air conditioning system when a unit abnormality occurs, to maximize the functions of the intelligent air conditioning system, and to provide the most comfortable air conditioning use environment to the user.
