Description

Filter life warning system and alarm method for air conditioning equipment

The invention relates to an air conditioning device, in particular to a filter net life warning system of an air conditioner and an alarm method thereof.

Referring to Fig. 1, there is shown a schematic diagram of a related art air conditioner. As shown in FIG. 1 , the air conditioner 1 is generally provided with a filter screen 11 , and the filter screen 11 is mainly disposed between the air inlet 12 and the air outlet 13 of the air conditioner 1 . The air conditioner 1 draws outside air from the intake port 12 and filters it through the filter 11, and then discharges the filtered air through the air outlet 13, thereby achieving the purpose of air circulation adjustment.

In general, the screen 11 is getting dirty due to prolonged use (because the dust and dirt of the air flowing through the air conditioner 1 are filtered out). An excessively dirty filter 11 will affect the efficiency of the circulation adjustment of the air conditioner 1, and thus waste energy due to lower efficiency. In order to maintain good performance of the air conditioner 1 and avoid energy waste, the user needs to periodically clean or replace the screen 11 in the air conditioner 1.

Although the manufacturer of the air conditioner 1 often reminds the user to periodically clean or replace the filter 11 in the instruction manual, most users forget it, thereby making the efficiency of the air conditioner 1 lower and lower, and wasting the air conditioner. 1 energy.

In view of this, some air conditioners 1 are additionally provided with a timing device to automatically accumulate the use time of the screen 11 (i.e., the operation time after the air conditioner 1 is installed with the screen 11). Moreover, the air conditioner 1 will actively send a reminder message for cleaning or replacing the filter 11 when the preset usage time (for example, 30 days) arrives to remind the user to clean or replace the filter 11.

However, the degree of filth of the screen 11 is quite correlated with the air quality in the environment. For example, when the amount of dust in the air is large, the screen 11 may be blocked in a short time. According to the above technique, the air conditioner 1 does not actively issue a reminder message for replacing the filter screen 11 until the use time of the filter screen 11 is reached, so that the user cannot replace the filter screen 11 in advance. As a result, the performance of the air conditioner 1 will be significantly reduced before the above usage time is reached.

As another example, when the amount of dust in the air is relatively small, the screen 11 may still be quite clean after the above-mentioned usage time has elapsed. In this case, the air conditioner 1 will still actively send a reminder message to replace the filter 11, but the reminder message will not be meaningful.

The main object of the present invention is to provide a filter life warning system and an alarm method for an air conditioner, which can calculate the life of the filter with reference to a plurality of parameters at the same time, so as to make the generated and issued alarm information more accurate.

In order to achieve the above object, the filter life warning method of the air conditioner of the present invention is applied to an air conditioner in which a filter and a fan are disposed, and includes:

c) determining that the air conditioner is activated and the fan is turned on, the processor obtains an environmental parameter by a sensor, wherein the sensor is disposed in the same space as the air conditioner, and the sensor senses the The environmental parameter within the space;

d) the processor calculates an operation time of the air conditioner when it is determined that the air conditioner has been activated and the fan is turned on;

e) executing, by the processor, an alarm algorithm to calculate a logic loss value of the filter according to the number of fan segments, the environment parameter, and the running time;

f) the processor determines whether the logic loss value is greater than a replacement threshold; and

g) When it is determined that the logic loss value is greater than the replacement threshold, an alarm message generated by the processor is generated and sent by the processor.

In order to achieve the above object, the screen life warning system of the air conditioning apparatus of the present invention includes:

The life expectancy can be obtained more accurately than the judgment method adopted by the related art.

DETAILED DESCRIPTION OF THE INVENTION A preferred embodiment of the present invention will be described in detail with reference to the drawings.

Please refer to FIG. 2 and FIG. 3 , which are respectively a schematic diagram of an air conditioner and a block diagram of an alarm system according to a first embodiment of the present invention.

An embodiment of the present invention discloses a filter life warning system (hereinafter referred to as alarm system 2) of an air conditioner. In the embodiment of FIG. 3, the alarm system 2 includes at least a ventilation (Air Conditioning and Air Conditioning, HVAC). 3. Sensor 4 and server 5. The server 5 can be a local server or a cloud server. In the embodiment of FIG. 3, the air conditioner 3, the sensor 4, and the server 5 are connected to each other through a network system (for example, Wi-Fi, Bluetooth, etc.), but can also be connected by a cable (not shown) ) Physical connections are not limited.

As shown in FIG. 2, in the present embodiment, the air conditioner 3 mainly has a strainer 31, a fan 32, a cooling coil 33, and a heating coil 34. When the air conditioner 3 is activated and the fan 32 is turned on, external wind can be drawn into the air conditioner 3 by the air inlet, and the harmful substances in the wind (for example, organic volatiles (TVOC)) are filtered by the filter 31 in the air conditioner 3. Or dust (DUST), etc.). Then, the wind in the air conditioner 3 is caused to flow to the cooling coil 33 or the heating coil 34 via the fan 32 to generate cold air or hot air required by the user, and then blown out of the air conditioner 3 via the air outlet.

As shown in FIG. 2, the air conditioner 3 and the one or more sensors 4 are disposed in the same space 8 in this embodiment. Specifically, the space 8 has one or more ventilation holes 81, and the cold air or hot air provided by the air conditioner 3 flows into the space 8 through the ventilation holes 81, thereby adjusting the environmental comfort in the space 8 to achieve environmental comfort. User 9 needs.

The sensor 4 is mainly used to sense various environmental parameters in the space 8. In one embodiment, the environmental parameter may be, for example, at least one of an organic volatile concentration value, a dust concentration value, and a formaldehyde concentration value, and the sensor 4 may be a sensing for sensing the environmental parameters. But not limited.

One of the main technical objects of the present invention is to calculate the life of the filter screen 31 in the air conditioner 3 according to various parameters, and to issue an alarm message to the user 9 or the manager when determining that the life of the filter 31 has expired. The user 9 or the manager is reminded to clean or replace the filter 31.

The alarm system 2 of the present invention mainly performs the above determination and sends an alarm message through a processor (not shown). In an embodiment, the processor may be a processor of the air conditioning device 3 (ie, performing local end operations by the air conditioning device 3). In another embodiment, the processor may be a processor of a remotely located server 5 (eg, a cloud server) (ie, performing cloud computing by the server 5). If the local terminal operation is performed by the air conditioner 3, the alarm system 2 of the present invention can eliminate the need to configure the server 5, thereby reducing the manufacturing cost. On the other hand, if the cloud computing is performed by the server 5, the efficiency and accuracy of the alarm system 2 can be greatly improved by the performance of the server 5.

For convenience of explanation, the cloud computing operation performed by the processor of the server 5 will be exemplified below, but the scope of the present invention is not limited thereto.

Specifically, the present invention determines whether the air conditioner 3 is activated by the processor, and determines whether the fan 32 of the air conditioner 3 is turned on. When it is determined that the air conditioner 3 has been activated and the fan 32 has been turned on, the processor then obtains the number of fan segments that the fan 32 is currently set by the air conditioner 3, and obtains various environmental parameters in the space 8 by the sensor 4 (for example, organic volatilization) The material concentration value, the dust concentration value, and the like), and the operation time of the air conditioner 3 is continuously calculated. And, the processor further executes an alarm algorithm 51 to calculate the life of the screen 31 of the air conditioner 3.

Specifically, after the air conditioner 3 is started, the air conditioner 3 transmits the number of fan segments to the server 5 via the communication connection, and the sensor 4 transmits the environmental parameters to the server 5 via the communication connection, and the server 5 is accumulated by the processor. The operating time of the air conditioner 3. Moreover, the processor executes an alarm algorithm 51, and the alarm algorithm 51 calculates the logical loss value of the filter screen 31 in the air conditioner 3 according to the obtained number of fan segments, environmental parameters, and operation time. In one embodiment, the logic loss value is inversely proportional to the lifetime of the screen 31, ie, the greater the logic loss value, the more severe the loss of the screen 31 (ie, the shorter the remaining life). When the logic loss value is greater than a certain value, it means that the life of the filter 31 is exhausted. However, the above is only one specific example of the present invention, but is not limited thereto.

In the present invention, the alarm algorithm 51 can record a replacement threshold value. In an embodiment, the administrator may perform repeated experiments on the air conditioner 3 and the filter 31 to obtain an exact value, and write the value into the alarm algorithm 51 as the replacement threshold. In another embodiment, the administrator may import all related information such as the air conditioner 3, the fan 32, the filter 31, the sensor 4, the space 8 and the user 9 into the alarm algorithm 51, and the alarm algorithm 51 is used. The above replacement threshold is calculated by big data analysis.

In the present embodiment, the replacement threshold value represents the maximum tolerable loss of the filter screen 31. After the alarm algorithm 51 calculates the above-mentioned logic loss value, the processor may further determine whether the logic loss value is greater than the replacement threshold value. When the logic loss value is greater than the replacement threshold value, it means that the current loss degree of the filter screen 31 has exceeded the maximum tolerable loss degree (that is, the life of the filter screen 31 has expired), so the processor generates and issues an alarm of the filter screen 31. A message to remind the user 9 or the manager to clean or replace the filter 31 of the air conditioner 3.

In the embodiment of FIG. 3, the processor is a processor of a server 5 (for example, a cloud server), and the alarm algorithm 51 is disposed in the server 5. In another embodiment, the processor may also be a processor of the air conditioner 3, and the alarm algorithm 51 may be a firmware of the air conditioner 3 (not shown).

In the embodiment of FIG. 2, the sensor 4 is disposed inside or around the space 8 with the air conditioner 3. In another embodiment, the sensor 4 can be directly disposed in the air conditioner 3 to make the installation of the alarm system 2 easier.

In the embodiment of FIG. 3, the alarm system 2 further includes a front console 6 communicatively coupled to the processor. In this embodiment, the front control panel 6 can be disposed, for example, in the space 8 or in the maintenance center of the air conditioner 3. The processor may send an alarm message of the filter 31 to the front panel 6 when the logic loss value is greater than the replacement threshold. Thereby, the user 9 or the administrator can view the alarm message on the front panel 6 and perform the cleaning or replacement operation of the screen 31 when the alarm message display screen 31 has reached the end of its life.

In the embodiment of FIG. 3, the alarm system 2 further includes a user terminal 7 communicatively coupled to the processor. The user terminal 7 is mainly carried by the administrator or the user 9 in the space 8, and the user terminal 7 is internally installed and executed with an application 71 compatible with the alarm system 2 of the present invention. In this embodiment, the processor may send the alarm message of the filter 31 to the user terminal 7 to display by the application 71 when the logic loss value is greater than the replacement threshold. Thereby, the user 9 or the administrator can view the alarm message on the user terminal 7, and when the alarm message display screen 31 has reached the end of its life, the cleaning or replacement action of the filter 31 is performed.

Referring to FIG. 4, it is an alarm flowchart of the first embodiment of the present invention. The invention further discloses a filter life warning method for an air conditioner (hereinafter referred to as an alarm method), and the alarm method is mainly applied to the air conditioner 3 and the alarm system 2 as shown in FIG. 2 and FIG.

In the alarm method of the present invention, first, the processor (i.e., the air conditioner 3 or the server 5) continuously determines whether the air conditioner 3 is activated, and determines whether the fan 32 of the air conditioner 3 is turned on (step S10). In an embodiment, a person sensor may be disposed in the space 8, and when the person sensor senses that the user 9 enters the space 8, the air conditioner 3 is automatically activated and the fan 32 is turned on. In another embodiment, after entering the space 8, the user 9 can manually issue an instruction through the input interface (for example, the front control panel 6 or the user terminal 7) to trigger the air conditioner 3 to start, and further turn on the fan 32.

Before the air conditioner 3 is activated and the fan 32 is turned on, the alarm system 2 of the present invention does not calculate the life of the screen 31 (ie, does not perform the alarm method of the present invention), but continuously detects the state of the air conditioner 3, It is judged whether or not the air conditioner 3 is activated, and it is judged whether or not the fan 32 is turned on. It is worth mentioning that if the air conditioner 3 is activated, but the fan 32 is not turned on, it means that no wind flows into the air conditioner 3. In this case, since the filter 31 does not perform the work of filtering out the dirt, the life of the screen 31 is not attenuated, so the alarm system 2 also does not calculate the life of the screen 31. In other words, the power state of the air conditioner 3 and the switch state of the fan 32 also belong to one of the parameters of the life of the filter 31 of the present invention.

After determining that the air conditioner 3 has been activated and the fan 32 has been turned on, the processor then obtains the number of fan segments currently set by the fan 32 by the air conditioner 3 (step S12), and the environment in the space 8 is obtained by the sensor 4. The parameter (step S14), and the operation time of the air conditioner 3 is calculated (step S16).

In an embodiment, the environmental parameter may be, for example, an organic volatile matter (TVOC) concentration value, a dust (DUST) concentration value, a formaldehyde concentration value, and the like in the space 8, and is not limited.

In an embodiment, the running time may be calculated by the processor after the air conditioner 3 is started, or calculated by the air conditioner 3, and the processor sends a request to the air conditioner 3 to obtain the running time, which is not limited. .

It is worth mentioning that the above steps S12 to S16 have no fixed execution order, and the processor can obtain the above parameters sequentially according to any order, or obtain all the above parameters simultaneously by multiplexing processing, instead of The sequence of steps shown in Figure 4 is limited.

After step S16, the processor has obtained various parameters required for calculating the filter 31, so the processor can transmit the fan segment number, the environmental parameter and the running time to the alarm algorithm 51, whereby the alarm algorithm 51 can be based on the fan. The logical loss value of the filter 31 is calculated by the number of segments, the environmental parameters, and the operation time (step S18).

In an embodiment, the air conditioner 3 may be provided with a plurality of fan segments (for example, ultra high speed (HH), high speed (Hi), medium (Me), and low speed (Lo), and the number of each fan segment is different. Wind flow.

Specifically, it has been experimentally found (refer to Table 1 below) that when the fan 32 of the air conditioner 3 is fixedly operated at the same fan section number, the flow of the wind through the air conditioner 3 is fixed. Moreover, when the fan 32 of the air conditioner 3 operates at a different number of fan segments, the flow rate of the wind will change correspondingly.  <TABLE border="1" borderColor="#000000" width="85%"><TBODY><tr><td> Wind flow (unit: CMH(m³/h)) </td></tr><tr><td> fan segment number product number</td><td> HH </td><td> Hi </td><td> Me </td><td> Lo </td></tr><tr><td> HVAC-1 </td><td> 412 </td><td> 370 </td><td> 307 </td><td> 225 </td></tr><tr><td> HVAC-2 </td><td> 299 </td><td> 269 </td><td> 225 </td><td> 163 < /td></tr><tr><td> Air volume ratio</td></tr><tr><td> </td><td> 1 </td><td> 0.89~0.91 </td ><td> 0.72~0.76 </td><td> 0.52~0.56 </td></tr></TBODY></TABLE>

Table I

As shown in the above table, in an embodiment, the alarm algorithm 51 may first convert the number of fan segments currently set by the air conditioner 3 into the flow rate of the airflow through the air conditioner 3 in the above step S18, and then according to the flow rate, the environmental parameters, and The operating time of the air conditioner 3 calculates the logical loss value of the screen 31. The alarm algorithm 51 can convert the number of fan segments into traffic by means of a table lookup (for example, querying the above table 1), or convert the number of fan segments into traffic by dynamic calculation. However, the above is only one specific example of the present invention, but is not limited thereto.

It is worth mentioning that the alarm algorithm 51 can be manually set by the administrator or automatically generate one or more weights via big data analysis. In step S18, the alarm algorithm 51 can mainly calculate the above-mentioned flow rate, operation time, environmental parameters, and product values of one or more weights, and then use this product value as the above-mentioned logic loss value.

After step S18, the processor determines whether the calculated logical loss value of the alarm algorithm 51 is greater than a pre-acquired replacement threshold (step S20). In the present invention, the air conditioner 3 and the filter 31 can be repeatedly tested by the manager, or the big data analysis can be performed by the alarm algorithm 51 to calculate the replacement threshold value that best matches the filter 31.

Specifically, the parameters used by the alarm algorithm 51 for calculating the logic loss value (including the above-mentioned flow rate, environmental parameters, and operation time) are parameters related to the life of the filter 31. When the logic loss value calculated by the alarm algorithm 51 according to the above parameter exceeds the replacement threshold value, it indicates that the life of the filter 31 has expired, and therefore, the processor further generates and sends an alarm message of the filter 31 (step S22). The action of cleaning or replacing the filter 31 of the air conditioner 3 by the user 9 or the manager is reminded.

In an embodiment, the processor may send the generated alarm message to the foreground control panel 6 of the alarm system 2. In another embodiment, the processor may send the generated alert message to the user terminal 7 carried by the user 9 in the space 8.

It is worth mentioning that after the filter 31 is cleaned or replaced, the processor can update the relevant parameters of the filter 31 (step S24). Specifically, in step S24, the processor stores the above-mentioned known parameters (including flow rate, environmental parameters, operation time, etc.) to the historical database of the alarm system 2 (not shown), and the parameters are Cleared from the local scratchpad. Thereby, the alarm system 2 can convert the previous usage record of the filter 31 into a history record, and store the usage record of the new filter screen 31 by the cleared register.

If the processor determines in step S20 that the logical loss value is not greater than the replacement threshold value, the processor further determines whether the air conditioner 3 or the fan 32 is turned off (step S26). If neither the air conditioner 3 nor the fan 32 is turned off, the processor again performs steps S12 to S20 to continuously obtain various parameters related to the life of the screen 31 of the air conditioner 3, and calculate the logical loss value of the filter 31. Thereby, it is continuously determined whether it is necessary to clean or replace the filter 31.

If it is determined in step S26 that the air conditioner 3 is turned off, or the air conditioner 3 has not been turned off but the fan 32 is turned off, the processor temporarily stores the parameters acquired in steps S12 to S16 (step S28), and then ends. This alarm method. When the air conditioner 3 is activated again and the fan 32 is turned on again, the processor reads the parameters stored in the previous step S28 from the register, and executes the steps shown in FIG. 4 based on the previously stored data. . Thereby, there is no problem that the calculation of the logic loss value of the filter screen 31 is inaccurate due to frequent opening/closing of the air conditioner 3.

Referring to Figure 5, there is shown a schematic diagram of the calculation of the life of the screen of the first embodiment of the present invention. As shown in FIG. 5, the alarm method of the present invention mainly performs early warning calculation of the life of the filter screen 31 of the air conditioner 3 by at least four parameters.

Specifically, among the at least four parameters, the parameter one is to determine whether the air conditioner 3 is activated, and whether the fan 32 is turned on; and the second parameter is that after the fan 32 is turned on, the wind flow is converted according to the number of fan segments used by the air conditioner 3 The flow rate of the filter 31; the third parameter is to detect the concentration of harmful substances (such as organic volatiles, dust, formaldehyde, etc.) in the environment; the fourth parameter is to calculate the running time of the air conditioner 3.

After obtaining the above at least four parameters, the alarm system 2 can perform the filter life warning calculation through the alarm algorithm 51. Moreover, the alarm system 2 can alert the user or the manager by issuing the above alarm message when the calculation result reaches the standard. Thereby, the present invention can make the calculated filter life more accurate.

Referring to FIG. 6, a schematic diagram of related parameters of a first embodiment of the present invention is shown. In an embodiment, the air conditioner 3, the sensor 4 or the server 5 can transmit the above parameters to the front panel 6 or the user terminal 7 to be controlled by the front panel 6 or the user terminal 7. display. Thereby, the user 9 and the manager can clearly see various data relating to the life of the screen 31 in the air conditioner 3.

For example, in the embodiment of FIG. 6, the user 9 and the manager can see the power state of the air conditioner 3, the state of the fan 32, and the organic volatile concentration value in the space 8 from the front panel 6 or the user terminal 7. The dust concentration value in the space 8, etc., but is not limited. By displaying the above parameters, the user 9 and the manager can be made aware of the current state of the air conditioner 3, the fan 32, and the environment in which the environment is located, thereby prolonging the life of the filter 31 by improving the air conditioner 3, the fan 32, or the environment in which the air conditioner 3, the fan 32, or the environment is located. .

Through the alarm system and the alarm method of the invention, it is possible to obtain a more accurate filter life calculation result than the judgment method adopted by the related technology, thereby enabling the user or the manager to more efficiently clean the filter screen of the air conditioner. Or change the action.

The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, equivalent changes to the scope of the present invention are included in the scope of the present invention. Bright.
