Description

  The present invention relates to an air conditioning monitoring and control system that performs air conditioning control of various buildings such as multipurpose intelligence buildings, office buildings, and general residential buildings.

  In recent years, management of air conditioning control is indispensable in building equipment management. In the air conditioning control of a building, a set temperature is generally set for each air conditioning target area, and control is performed so that the temperature in the air conditioning target area approaches the set temperature.

  Several air conditioning control technologies have been proposed for conventional air conditioning monitoring and control systems (Patent Documents 1 and 2).

  In the air conditioning control technology described in Patent Literature 1, a control monitoring device is connected via a network to a client terminal equipped with a web browser that monitors the operation control and operation state of an air conditioner installed in each air conditioning target area. The monitoring device creates operation schedule screen data of the air conditioner by HTML and transmits it to the client terminal. The client terminal displays the operation schedule screen received from the control and monitoring device, and the operation schedule screen displays the operation type of the air conditioning unit in one of the cooling mode, heating mode, and operation stop color-coded. The set temperature and current room temperature are displayed.

On the other hand, the air conditioning control technology described in Patent Document 2 is provided with light emitting means such as LEDs whose light color and intensity can be changed in or near the air conditioner installed in the room of a general residential building. Based on the control, the light emitting means emits blue light during cooling, the light emitting means emits red light during heating, and the luminous intensity of the light emitting means is varied according to the temperature deviation between the set temperature and the current room temperature. This technology makes you feel comfortable visually.

  First, prior to describing an embodiment of an air conditioning monitoring and control system according to the present invention, an outline of an air conditioning target area in a building and an air conditioning system will be described.

  FIG. 1 is an example diagram showing the relationship between the number of air-conditioning target areas and the number of air conditioners on an arbitrary floor of a building. In general, in a building, a plurality of air-conditioning target areas (rooms) 1a to 1n are formed for each floor, and the required number of air conditioners 2 are divided according to the air-conditioning capacity or air-conditioning capacity, and each air-conditioning target area 1a to 1n Air conditioning. Incidentally, FIG. 1 schematically shows a plan view or a sectional view of the second floor of the building. The second floor of the building is composed of, for example, 10 air-conditioning target areas 1a to 1j, and three air conditioners 2 are provided. In this example, air conditioning is performed by dividing the air-conditioning target areas (1a, 1b, 1f, 1g), (1c, 1d, 1h, 1i), and (1e, 1j). On the other floors as well, an arbitrary number of air conditioners 2 are installed for a plurality of air conditioning target areas.

  FIG. 2 is a diagram illustrating an example of an air conditioning system. The air conditioning system includes a damper 3 that adjusts the flow rate of outside air and exhaust, an air conditioner 2 that generates heat at a desired temperature by exchanging heat between the outside air taken in via the damper 3 with cold water or hot water, and the air conditioner. After air-conditioning the air blower 4 that blows the air generated in 2, the supply duct 5 that guides the air output from the air blower 4 to the air-conditioning target area, for example, 1 a, 1 b,. It comprises an exhaust duct 6 that discharges air to the outside, an air fan 7, and a VAV (variable air volume) unit 8 that is installed in the air-conditioning air intake portion of each air-conditioning target area 1a, 1b,. The VAV (variable air volume) unit 8 is provided with a damper or an air volume adjustment movable plate (hereinafter, generically referred to as an air volume adjustment plate) in an air blowing portion, and controls the opening degree of the air volume adjustment plate to control the air volume of air to be used for cooling and heating. Adjust.

  In addition, the air conditioning system controls the flow rate of cold water or hot water to the air conditioner 2, and the opening degree of the air volume adjusting plate such as the VAV (variable air volume) unit 8 corresponding to each air conditioning target area 1a, 1b,. An air conditioning control computer 10 that controls and adjusts the air conditioning air volume is installed.

  That is, the air conditioning control computer 10 measures, for example, the room temperature T and the humidity H in each air conditioning target area 1a, 1b,..., And takes in either cold water or hot water according to the cooling / heating operation mode. The cooling coil CC or the heating coil HC exchanges heat with the outside air, and feeds cold air or hot air to each VAV unit 8 through the blower 4. At this time, the air conditioning control computer 10 calculates an operation amount corresponding to the deviation between the measured room temperature T and the set temperature, and controls the opening of the air volume adjusting plate of the VAV unit 8, for example.

(Embodiment 1: corresponding to claims 1 to 3)
FIG. 3 is a basic configuration diagram for explaining each embodiment of the air conditioning monitoring control system according to the present invention.

  In the air conditioning monitoring control system, a data transmission path 11 is laid across each floor of a building. As described above, the data transmission path 11 stores a plurality of air conditioning control computers (controllers) 10 that monitor and control at least one air conditioner 2, and data related to air conditioning control of each air conditioning control computer 10. At least one server station 12,... Is connected to a human interface station (hereinafter referred to as an HMI station) 13.

  The air-conditioning control computer 10 measures and collects data (room temperature T, humidity H, etc.) necessary for air-conditioning control in each air-conditioning target area, and provides an operation amount such that the deviation between the current room temperature T and the set temperature becomes zero. The flow rate of cold air or hot water supplied to the air conditioner 2 is controlled according to the obtained operation amount, and the opening degree of the air volume adjusting plate of the VAV unit 8 is controlled.

  Each server station 12 receives the room temperature T, the operation amount, the set temperature, the absolute humidity, etc. of each air conditioning target area measured and collected by the corresponding air conditioning control computer 10, and further the room temperature of each air conditioning target area at a predetermined cycle. Data necessary for executing a calculation algorithm for performing prediction (Embodiment 3 described later) is stored, and a deviation between the current room temperature T of each air-conditioning target area and a set temperature is always calculated for each air-conditioning target area. Various data are accumulated in time series.

  The HMI station 13 includes a database 13a, a display unit 13b, and an input unit 13c such as a keyboard and a mouse, and executes predetermined processing under monitoring and operation by an operator.

  In the database 13a of the HMI station 13, in addition to the deviation temperature data table 13a1 and the air conditioning control status symbol table 13a2, various data collected from the air conditioning control computer 10 for each air conditioning target area and a set temperature are stored. Is provided.

  In the deviation temperature data table 13a1, as shown in FIG. 4, paint color data (hereinafter referred to as color data) of an air-conditioning target area for each predetermined deviation temperature range between a preset temperature (set room temperature) and the current room temperature is provided. It is remembered. As a result, the HMI station 13 shows the lightness and darkness expressing “hot” when the current room temperature is higher than the set temperature from the deviation temperature data table 13a1 according to the deviation between the set temperature in the air-conditioning target area and the current room temperature. If the current room temperature is lower than the set temperature, color data including shades representing “cold” is extracted and the corresponding air-conditioning target area is displayed in color.

  On the other hand, as shown in FIG. 5, symbol mark data representing the air conditioning control status is stored in the air conditioning status symbol table 13a2 for each VAV opening range (%) based on the operation amount ΔMV to the VAV unit 9. The symbol mark is a mark that allows the operator to visually recognize the air conditioning control status instantaneously. For example, as shown in the figure, the right shoulder rises to raise the room temperature during heating and the room temperature to lower during cooling. It represents an image in which the inclination angle gradually increases as the VAV opening degree range (%) increases with a decrease.

  The symbol mark may be any mark that can visually recognize the air conditioning control status instantaneously. For example, as shown in FIG. 6, the opening range (%) of the VAV unit 9 and the plate movable angle of the air volume adjusting plate in the VAV unit 9. It may be a mark that gives an image of the relationship between In addition, the symbol mark itself shown in FIG. 5 and FIG. 6 is red when heating, and the blue mark when cooling, or only the symbol rising upward during heating shown in FIG. You may display with the color data which is blue at the time of air_conditioning | cooling.

  Next, the operation of the air conditioning monitoring control system as described above will be described with reference to FIG.

  The computer 10 for air-conditioning control always calculates a deviation between the current room temperature and the set temperature based on the set temperature of the air-conditioning target areas 1a and 1b, and obtains an operation amount that makes the calculated deviation zero. The opening degree of the air volume adjusting plate of the VAV unit 8 is controlled.

  At this time, the HMI station 13 executes a series of processes as shown in FIG.

  The HMI station 13 determines whether, for example, one or more monitoring instructions for the air conditioning control computer 10 are input from the operator through the input unit 13c (S11, S12,...). When it is determined that there is a monitoring instruction, as shown in FIG. 8, the air-conditioning area screen data of a plurality of air-conditioning target areas, for example, 1a and 1b to be controlled by the corresponding air-conditioning control computer 10, is edited and the air-conditioning area screen is displayed on the display unit 13b. 14 is displayed (S2).

  After displaying the air conditioning area screen 14, the HMI station 13 determines whether or not a predetermined period (for example, a calculation period) is reached (S3), and when the HMI station 13 determines that the predetermined period has been reached, the HMI station 13 manages the air conditioning control computer 10. The current room temperature, set temperature, and other necessary data of one air-conditioning target area 1a are fetched, for example, the operation amount by the computer 10 for air conditioning control, and the set temperature 25 ° C. and the current room temperature 26.6 ° C. in the air-conditioning area screen 14 are displayed. Then, the deviation (deviation temperature) between the set temperature and the current room temperature is calculated (S4). Steps S11 to S1N and S2 to S4 correspond to area temperature display means.

  The HMI station 13 calculates a deviation temperature (−1.6 ° C.) where the current room temperature is 1.6 ° C. higher than the set temperature based on a deviation (deviation temperature) calculation between the set temperature and the current room temperature. The air conditioning state of this air conditioning target area 1a is hotter than the set temperature.

  Therefore, the HMI station 13 refers to the deviation temperature data table 13a1 of the database 13a based on the deviation temperature of −1.6 ° C., and extracts red color data representing a hot state (S5). All areas corresponding to the air conditioning target area 1a are displayed in red (S6). Steps S5 to S6 correspond to area color display means.

  Subsequently, the HMI station 13 obtains the opening degree of the VAV unit 8 from the operation amount ΔMV to the VAV unit 9 corresponding to the air conditioning target area 1a, and then opens the opening from the air conditioning status symbol table 13a2 based on the obtained opening degree. For example, an arrow symbol mark representing the air conditioning control status is taken out from the opening range including the degree, and the current room temperature of 26.6 ° C. is being controlled to correspond to the current room temperature of 26.6 ° C. on the air conditioning area screen 14. Is displayed (S7). This step S7 corresponds to symbol mark display means.

  Then, after displaying the symbol mark, it is determined whether there is a next air-conditioning target area, and since there is still an air-conditioning target area 1b, the process returns to step S4 and the same processing is repeatedly executed. As a result, when the set temperature of the air conditioning target area 1b is 25.0 ° C. and the current room temperature is 23.6 ° C., the deviation temperature is + 1.4 ° C., and the air conditioning target area 1b is displayed in light blue and After obtaining the opening (for example, zero) of the air volume adjusting plate of the VAV unit 8 from the operation amount ΔMV for the air conditioning target area 1b by the control computer 10, the air conditioning control status in which the air volume adjusting plate is closed from the air conditioning status symbol table 13a2. For example, an arrow symbol mark is taken out, and a state where control is not currently performed is displayed.

  After a series of processes for all the air-conditioning target areas 1a and 1b is completed, the process returns to step S3 in the case of continuing the process in step S9, and the processes in steps S4 to S8 are repeatedly executed at predetermined intervals.

  Therefore, according to the above embodiment, the air-conditioning target areas 1a and 1b in the air-conditioning area screen 14 are displayed with color data representing hot and cold according to the temperature difference between the set temperature and the current room temperature. In addition, it is possible to instantly visually recognize whether the current room temperature of the air-conditioning target areas 1a and 1b is hotter than the set temperature or lower than the set temperature.

  Further, since the air conditioning control status, which is the operation amount to the VAV unit 8 corresponding to the air conditioning target areas 1a and 1b by the air conditioning control computer 10, displays a symbol mark indicating the size of the air conditioning and the current air conditioning control. Whether the room temperature is currently being raised or lowered, and the air conditioning control status including the magnitude of the control can be visually recognized instantly.

  That is, this air conditioning monitoring and control system can visually grasp the degree of deviation between the set temperature and the current room temperature and the air conditioning control status when there is a deviation.

(Embodiment 2: corresponding to claim 4)
The second embodiment is an example in which an operator receives a complaint from a resident of a building, accumulates it in the substation 12, and generates a complaint history for each air-conditioning target area.

  The HMI station 13 generates data of a buttoned air-conditioning area screen 14 ′ to which a complaint input button 14a and a complaint history button 14b are generated and added, a complaint input window screen 14c describing a plurality of complaint items, and a complaint history window screen 14d. , Stored in the database 13a, selectively displayed as necessary on the display unit 13b as necessary, and has a function of displaying a complaint history for each air-conditioning target area.

  On the other hand, the server station 12 includes a data storage database 12a. The data storage database 12a is provided with counter memories 12a1 to 12aN for integrating each claim item corresponding to each deviation range between the set temperature and the current room temperature at least for each air conditioning target area 1a, 1b,.

  Next, the operation of the air conditioning monitoring control system as described above will be described with reference to FIG.

  First, when the operator receives a complaint about the current room temperature from a resident in the air conditioning target area, for example, 1a, the operator inputs a display instruction for the buttoned air conditioning area screen 14 'including the air conditioning target area 1a from the input unit 13c.

  When receiving the display instruction from the input unit 13c (S11), the HMI station 13 reads the buttoned air-conditioning area screen 14 'including the air-conditioning target area 1a from the database 13a and displays it on the display unit 13b as shown in FIG. S12). Steps S11 to S12 correspond to air conditioning area display means.

  Here, when the operator clicks the complaint input button 14a (S13), a complaint input window screen 14c is displayed on the buttoned air conditioning area screen 14 '(S14). When the operator clicks, for example, a “hot” complaint item in accordance with the complaint content in the complaint entry window screen 14c (S15), the complaint acceptance time is identified in the identification data of the air-conditioning target area 1a and the “hot” complaint item data. Is transmitted to the server station 12 (S16). These steps S13 to S16 correspond to a claim transmission means.

  When the server station 12 receives the identification data of the air conditioning target area 1a and the complaint item data “hot”, the server station 12 counts the air conditioning target area 1a at the complaint acceptance time and the counter memory corresponding to the complaint item “hot”, for example 12a1. Up. At this time, the set temperature, the current room temperature, and the temperature difference (deviation) between the set temperature and the current room temperature in the air-conditioning target area 1a at the claim acceptance time are stored in association with the count value.

  On the other hand, if it is not the operation of the complaint input button 14a in step S13, the process proceeds to step S17, and it is determined whether or not the complaint history button 14b is clicked. Here, when it is determined that the complaint history button 14b has been clicked, history request data regarding the air-conditioning target area 1a is transmitted to the server station 12 (S18). Steps S13, S17, and S18 correspond to complaint history request means.

  When the server station 12 receives the history request data related to the air conditioning target area 1a, the server station 12 reads the count value for each predetermined temperature difference range from the counter memory corresponding to the air conditioning target area 1a, for example, 12a1, And transmitted to the HMI station 13.

  The HMI station 13 reads the data of the complaint history window screen 14d from the database 13, sequentially writes the total number of complaints in the corresponding area of the complaint history window screen 14d, and the complaint history window screen 14d as shown in FIG. Is displayed (S19). This step S19 corresponds to a complaint history screen display means.

  The complaint history window screen 14d represents the number of complaints as a numerical value, but may be displayed with a bar instead of the numerical value, for example.

  Therefore, according to the above embodiment, when the complaint input button 14a formed on the buttoned air-conditioning area screen 14 'is operated, the complaint input window screen 14c is displayed, and the complaint item corresponding to the content of the complaint is displayed. Therefore, it is possible for the operator to input the complaint contents relatively easily, and to accumulate the number of complaints in the substation 12 for each air-conditioning target area and for each temperature difference.

  Further, when the complaint history button 14b formed on the air-conditioning area screen 14 ′ with the button is operated, a complaint history is requested, and the total result data of the number of complaints in the air-conditioning target area 1a, for example, 1a is received from the substation 12. Since it is displayed as the history window screen 14d, the number of complaints of each complaint item for each air-conditioning target area can be easily grasped over a predetermined period.

  This ensures that the tendency of residents in the air-conditioning area representing indoor discomfort can be ascertained, and how much temperature difference a particular occupant has, or during summer cooling or winter heating. It is possible to easily analyze the direction of air-conditioning control for complaints from residents, such as whether or not a complaint comes out.

(Third embodiment: corresponding to claims 5 and 6)
The third embodiment is an example in which the server station 12 predicts a room temperature change up to a predetermined elapsed time in the air-conditioning target area based on an instruction of a room temperature change prediction by an operator on the HMI station 13 side, and provides and displays the change to the HMI station 13 It is.

  In the HMI station 13, a buttoned air conditioning area screen 14 "and a room temperature change status window screen 14f to which at least a room temperature prediction button 14e is added are generated on the air conditioning area screen 14, and stored in the database 13a.

  On the other hand, when the server station 12 receives an instruction for predicting the room temperature of an air-conditioning target area from the HMI station 13, various accumulated data acquired from the air-conditioning control computer 10 and data stored in advance, for example, heat load for each air-conditioning target area Based on the generation model (heat transfer model), it has a function of predicting a room temperature change until a predetermined elapsed time of the air-conditioning target area and providing it to the HMI station 13.

  FIG. 12 shows, as an example of the indoor temperature change prediction calculation, at least the heat capacity related to the air-conditioning target area, the current room temperature, and the operation amount of the air conditioner, and the room temperature change for n minutes (for example, 5 to 10 minutes) every predetermined time. Predict.

  Here, the heat capacity related to the air-conditioning target area is calculated for each predetermined time based on the following calculation algorithm using, for example, the heat transfer model of the air-conditioning target area shown in FIG. Note that the walls of the air-conditioning target area are grouped into four types of walls as shown in FIG. The wall structure can be approximated by two layers: concrete and insulation.

Now, assuming that the room temperature T _R , the indoor absolute humidity X _R , the outside air temperature T _l , and the heat capacity _CRM of the air conditioning target area are the air conditioning target area, the heat capacity is obtained from the following equation (1) to (3). .

  Next, the operation of the air conditioning monitoring control system as described above will be described with reference to FIG.

  When the operator inputs a room temperature prediction instruction for the air conditioning target area, for example, 1a from the input unit 13c, the HMI station 13 determines in step S21 that there is a room temperature prediction instruction for the air conditioning target area 1a, and at least selects the air conditioning target area 1a. The air-conditioning area screen 14 "is displayed (S22). Steps S21 and S22 correspond to air-conditioning area display means.

  After displaying the air conditioning area screen 14 ", the HMI station 13 determines whether or not the room temperature prediction button 14e has been selected (S23). When it is determined that there is an operation, the HMI station 13 sends the room temperature prediction request data regarding the air conditioning target area 1a to the server. The data is transmitted to the station 12 (S24) Steps S23 and S24 correspond to predicted data request transmission means.

  When the server station 12 receives the room temperature prediction request data related to the air conditioning target area 1a from the HMI station 13 (S31), the room temperature T (Δt after several minutes from the room temperature T (t) at the current time t of the air conditioning target area 1a ( t + Δt) is a room temperature representing a change in room temperature, for example, every minute from the current time to T (t + Δt) after calculating n minutes (for example, 5 minutes) after the current time based on the following formula, for example. Data of the change prediction result is calculated, converted into a file, and transmitted to the HMI station 13 (S32).

T (t + Δt) = T (t) + {(T ₁ −T (t)) / R} + (nT / C) (4)
However, C is the heat capacity related to the target air-conditioning area, R is the indoor thermal resistance, and T _l is the outside air temperature.

  When the HMI station 13 receives the file of the room temperature change prediction result filed from the server station 12 (S25), the HMI station 13 reads the room temperature change state window screen 14f from the database 13a, and based on the room temperature change prediction result data and the set temperature data. In the room temperature change status window screen 14f, the horizontal axis is time (minutes), the vertical axis is temperature, and the room temperature change converges to the set temperature after the set temperature at the current time, or does not converge at all. The line graph data indicating the state in which the control ends is written and displayed on the display unit 13b as shown in FIG. 14 (S26). Steps S25 and S26 correspond to air conditioning prediction result display means.

  Thereafter, the HMI station 13 determines whether or not to continue the process. If the process is continued, the process returns to step S21. If the process is not continued, the HMI station 13 ends.

  Therefore, according to the embodiment as described above, the HMI station 13 receives the temperature change prediction result up to a predetermined time from the server station 12 based on the room temperature prediction request data related to the air-conditioning target area 1a, and displays, for example, a graph display. Therefore, it is possible to visually grasp the deviation between the room temperature and the set temperature after a predetermined time, and as a result, whether the air-conditioning control is properly performed or the control has been completed without converging at all. You can understand the necessity of taking such measures.

(Other embodiments)
(1) In the first embodiment, the color data is defined for each deviation temperature range in the deviation temperature data table 13a1 shown in FIG. 4, but other color data may be used. Further, for example, a bar graph that can image the degree of deviation instead of the color may be used, and color data may be attached to the bar graph.

(2) In the second embodiment, as an input method of the complaint, the operator receives the complaint content from the resident and inputs the complaint from the complaint input window screen 14c. May be input from the resident's personal computer instead of the HMI station 13.

(3) Moreover, in the said Embodiment 3, the room temperature change prediction result was displayed by the line graph, For example, according to the magnitude | size of a temperature change value, for example, it represents with a numerical value (temperature change value) for every minute, for example, It may be red when the temperature change value is large, blue when there is almost no temperature change value reaching the set temperature, and the color change of the temperature change value of the trunk may be gradually changed. Moreover, you may represent the magnitude | size of a room temperature change with an image.

(4) As an example of obtaining the room temperature change prediction result after a few minutes from the current time, the server station 12 previously stores the time series changes of the room temperature, set temperature, manipulated variable, outside air temperature, time, etc. of each target air conditioning area. Since past data has been accumulated, data under substantially the same environmental conditions as the present time may be selected, and a room temperature change prediction after n minutes every predetermined time from the current time may be extracted and transmitted to the HMI station 13. In addition, the room temperature change prediction result may be calculated using various well-known prediction methods.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
