[0037] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. figure 1 Is the composition diagram of the air conditioning system of the present invention, figure 2 It is a block diagram of the air conditioning system of the present invention.
[0038] Such as figure 1 As shown, the air conditioning system of the present invention includes: a plurality of indoor units 50 and outdoor units 40; the Meteorological Agency server 30 for storing meteorological information; the server 20 storing meteorological information received from the Meteorological Agency server 30; The central controller 10 controls the operation of a plurality of indoor units 50 and outdoor units 40 based on the weather information.
[0039] And, as figure 2 As shown, the server 20 includes: a database 23 for storing weather information of various regions received from the Meteorological Agency server 30; a communication module 24 for sending and receiving data; reading the application signal received from the central controller 10, and detecting related The location detection unit 22 of the location information of the area; selects the weather information of the area corresponding to the detected location information from the weather information stored in the database 23 according to the received application, and sends it to the central controller 10 for processing部21。 Department 21.
[0040] The central controller 10 includes: a judging unit 12 that detects the setting status and operation mode of the multiple indoor units 50 connected; a memory for storing location information of the multiple connected indoor units 50 and the area where the outdoor units 40 are located 13; a communication module 14 for sending and receiving data; generates a weather information application signal including location information of a plurality of indoor units 50 and outdoor units 40, and sends it to the control unit 11 of the server 20.
[0041] The control unit 11 detects the information of the plurality of indoor units 50 and the outdoor unit 40 located in the relevant area based on the weather information, and controls the heating or cooling set temperature of the plurality of indoor units 50.
[0042] The control unit 11 detects the information of the connected multiple indoor units 50 and outdoor units 40 and stores it in the memory 13, and also stores the location information of the multiple indoor units 50 and outdoor units 40 in the memory 13.
[0043] The control unit 11 transmits to the server 20 an application signal including position information of the area where the plurality of indoor units 50 and outdoor units 40 are located in accordance with the applications of the plurality of connected indoor units 50 and outdoor units 40.
[0044] The Meteorological Agency server 30 collects and saves the weather state data of each region, and provides the saved weather information data to the server 20 according to the received application.
[0045] The Meteorological Agency server 30 transmits the changed weather information to the server 20 according to the setting when the weather information of the area to which the application is submitted changes.
[0046] The server 20 is connected to the Meteorological Agency server 30, downloads and saves the collected data, and provides the relevant central controller 10 with the saved weather information every time an application is received.
[0047] When connecting to the Meteorological Agency server 30, the processing unit 21 applies for the weather information for each area collected by the Meteorological Agency server 30, and stores the weather information in the database 23 when the server 20 receives the weather information.
[0048] The received weather information of each area is stored in the database 23, and when new weather information is received from the Meteorological Agency server 30, the weather information of the relevant area is upgraded and stored.
[0049] Moreover, when the processing unit 21 receives the weather information request signal for a specific area from the central controller 10, it filters out the weather information of the relevant area from the weather information of each area stored in the database 23 based on the location information detected by the location detection unit 22 And send weather information of the relevant area to the central controller 10.
[0050]When receiving weather information from the server 20 through an application, the central controller 10 generates a command for controlling the operation of the plurality of indoor units 50 based on the weather information, and transmits it to each outdoor unit 40.
[0051] The control unit 11 detects the information of the plurality of indoor units 50 and the outdoor unit 40 in the relevant area based on the weather information, and controls the heating or cooling set temperature of the plurality of indoor units 50.
[0052] That is, the control unit 11 resets the set temperature of the plurality of indoor units 50 located in the relevant area based on the outdoor temperature included in the weather information.
[0053] Before resetting the set temperatures of the plurality of indoor units 50, the determination unit 12 detects the operation mode, the set temperature, the minimum set temperature, the maximum set temperature, etc. of the plurality of indoor units 50 connected.
[0054] The control unit 11, based on the judgment result of the judgment unit 12, sets the set temperature of the indoor unit 50 to a temperature value greater than the predetermined value of the detected outdoor temperature when operating in the heating mode; and when operating in the cooling mode At this time, the set temperature of the plurality of indoor units 50 is set to a temperature value lower than the detected outdoor temperature predetermined value.
[0055] That is, when the control unit 11 receives weather information from the server 20, if the plurality of indoor units 50 are operating in the heating mode, the heating set temperature of the plurality of indoor units 50 is set to the base of the detected outdoor temperature The temperature value of the upper alpha value.
[0056] When the detected outdoor temperature is below the predetermined temperature, the control unit 11 enables the plurality of indoor units 50 to maintain the minimum heating setting temperature, and when the detected temperature exceeds the predetermined temperature, the control unit 11 enables the indoor unit 50 to Maintain the highest setting temperature for heating.
[0057] For example, when the minimum heating temperature of the plurality of indoor units 50 is 18 degrees and the maximum heating temperature is 30 degrees, the control unit 11 resets the heating set temperature (setting If the temperature + α) is less than the minimum set temperature (18 degrees), the plurality of indoor units 50 are maintained at the minimum set heating temperature (18 degrees), and if the heating set temperature is reset (outdoor temperature + α) When the maximum set temperature (30 degrees) is exceeded, the set temperature positions of the plurality of indoor units 50 are heated to the maximum set temperature (30 degrees).
[0058] Conversely, when the plurality of indoor units 50 are operating in the cooling mode, the control unit 11 sets the cooling set temperature of the plurality of indoor units 50 to a temperature value smaller than the detected outdoor temperature by the value β.
[0059] For example, when the detected outdoor temperature is 28 degrees and the β value is 10, the control unit 11 sets the set temperature of the plurality of indoor units 50 to 18 degrees (= 10 degrees lower than the detected outdoor temperature). 28-β).
[0060] However, when the detected outdoor temperature is below the predetermined temperature, the control unit 11 makes the plurality of indoor units 50 maintain the minimum cooling setting temperature, and when the detected temperature exceeds the predetermined temperature, the control unit 11 makes the plurality of indoor units 50 to maintain the maximum set temperature of refrigeration.
[0061] For example, when the cooling minimum set temperature of the plurality of indoor units 50 is 15 degrees, and the heating maximum temperature is 25 degrees, the control unit 11 resets the cooling set temperature (outdoor temperature- β) When the minimum set temperature (15 degrees) is reached, the set temperature position of the multiple indoor units 50 is cooled to the minimum set temperature (15 degrees), and when the set temperature of the multiple indoor units 50 (outdoor temperature- When β) exceeds the maximum set temperature (25 degrees), the set temperatures of the plurality of indoor units 50 are maintained at the maximum set temperature (25 degrees).
[0062] The control unit 11 does not limit α or β to a predetermined value, but can change the value of α or β by dividing the detected outdoor temperature in stages according to the setting.
[0063] That is, when the multiple indoor units 50 are operating in the heating mode, if the detected outdoor temperature is within the range of 0 degrees to 10 degrees, then α=10; the outdoor temperature is within the range of 10 degrees to 20 degrees, then α =5, the outdoor temperature is within the range of 20 degrees to 30 degrees, then α=2, which can set the value of α according to the stage.
[0064] When multiple indoor units 50 are operating in the cooling mode, if the detected outdoor temperature is within the range of 10 degrees to 20 degrees, then β=1; if the outdoor temperature is within the range of 20 degrees to 25 degrees, then β=4; If the outdoor temperature is within the range of 25 degrees to 30 degrees, then β=8, thus the β value can be set according to the stage.
[0065] The control unit 11 generates a command for controlling the air-conditioning operation based on the set temperature of the plurality of indoor units 50 reset as described above, and sends the command to the plurality of outdoor units 40 so that the plurality of indoor units 50 operate according to the command.
[0066] At the same time, the central controller 10 can make a specific indoor unit 50 of the plurality of connected indoor units 50 perform heating or cooling operation at a set temperature regardless of the received weather information according to the setting.
[0067] image 3 It is a schematic diagram of the curve when the set temperature is reset in the heating or cooling mode of the central controller of the present invention.
[0068] Such as image 3 As shown in a, the central controller 10 reads the weather information received from the server 20 during the heating operation, and resets the heating set temperature T1 of the plurality of indoor units 50 based on the outdoor temperature included in the weather information.
[0069] The minimum set temperature (T LOW ) Is 16, the maximum set temperature (T HIGH ) Is 30 degrees, "α=15", if the detected outdoor temperature (T) is within the range of "1
[0070] When the control section 11 sets the heating set temperature (T1) in the center, according to the judgment result of the judgment section 12, when the detected outdoor temperature is below 1 degree, it is set to the lowest set temperature, which is 16 degrees; and When the detected outdoor temperature is above 15 degrees, it is set to the highest set temperature, which is 30 degrees.
[0071] Such as image 3 As shown in another embodiment of the central controller 10 of b, during cooling operation, the central controller 10 reads the weather information received from the server 20, and resets the number of indoor units 50 based on the outdoor temperature included in the weather information. Cooling set temperature (T2).
[0072] The minimum set temperature (T LOW ) Is 14 degrees, the highest setting temperature (T HIGH ) Is 20 degrees, "β=10", if the detected outdoor temperature "T" is within the range of "24
[0073] When the control unit 11 resets the cooling set temperature (T2), when the detected outdoor temperature is below 24 degrees, it is set to the lowest set temperature, which is 14 degrees; and when the detected outdoor temperature exceeds 30 degrees When, set to the highest set temperature, that is, 20 degrees.
[0074] The working process of the present invention constituted as above is as follows.
[0075] Figure 4 It is a flowchart of the operation method of the air conditioning system of the present invention; FIG. 5 is a flowchart of the operation method of the central controller of the present invention.
[0076] Such as Figure 4 As shown, the central controller detects the location information S100 of the area where a plurality of indoor units and outdoor units are located, generates a weather information application signal of the relevant area, and sends it to the server S110.
[0077] The application signal contains the multiple indoor units connected and the location information of the area where the outdoor units are located.
[0078] The server is connected to the server of the Meteorological Agency that saves the weather information of each region, and saves the weather information S200 and S300 of each region downloaded from the server of the Meteorological Agency. Send to the central controller S210, S220.
[0079] The central controller reads the weather information received from the server S120.
[0080] The outdoor temperature S130 is detected from the received weather information, and the set temperature S140 of the plurality of indoor units is reset based on the detected outdoor temperature.
[0081] That is, the central controller sets the set temperature to be lower than or higher than the detected outdoor temperature according to the operation modes of the plurality of indoor units.
[0082] For example, when multiple indoor units are operating in heating mode, the central controller resets the set temperatures of multiple indoor units to be higher than the outdoor temperature, and when multiple indoor units are operating in cooling mode, the The set temperature of the machine is set to be lower than the outdoor temperature.
[0083] If the weather information of a specific area is changed S310, after receiving the changed weather information from the Meteorological Agency server S320, the server updates the weather information of the relevant area S230, and sends the updated weather information to the relevant central controller S240.
[0084] When the central controller receives new weather information from the server, it reads the information and resets the set temperature S120 to S140 of several indoor units based on the detected outdoor temperature, and sends related controls to multiple connected indoor units and outdoor units Command S150.
[0085] As shown in FIG. 5, the central controller determines the operation mode S131 of a plurality of indoor units and outdoor units connected to the central controller based on the outdoor temperature detected in the weather information received from the server.
[0086] When the plurality of indoor units are operating in the heating mode, the control unit sets the set temperature of the plurality of indoor units to be greater than the detected outdoor temperature by a predetermined value αS132.
[0087] When the plurality of indoor units are operating in the cooling mode, the control unit sets the set temperature of the plurality of indoor units to be lower than the detected outdoor temperature by a predetermined value βS133.
[0088] If the judgment unit compares the set temperature calculated from the detected outdoor temperature with the set maximum temperature, and then judges that the set temperature is lower than the set minimum set temperature S134, the control unit makes the multiple indoor units The set temperature reaches the lowest set temperature S135 in the heating or cooling mode.
[0089] Conversely, when the judgment unit compares the set temperature with the set maximum set temperature, and determines that the set temperature exceeds the set maximum set temperature of the multiple indoor units S136, the control unit causes the multiple indoor units to The set temperature reaches the highest set temperature S137 in the heating or cooling mode.
[0090] The control unit generates a control command based on the reset set temperature, and transmits the command to a plurality of connected indoor units and outdoor units.
[0091] If the control unit receives the updated weather information S138 from the server, it reads the weather information and re-detects the outdoor temperature, and then resets the heating or cooling set temperatures of the multiple indoor units based on the re-detected outdoor temperature S131 to S137 .
[0092] The above is a description of the air conditioner system and its operation method provided by the present invention with reference to the drawings, but the content of the present invention is not limited to the embodiments and drawings.
