  The present invention relates to an air conditioner usage status diagnosing device, and more particularly to an apparatus for diagnosing the air conditioner usage status for indoor cooling, heating and dehumidification.

  Air conditioners used in office buildings, factories, etc. cool, dehumidify, humidify, and dehumidify indoor spaces so that the temperature, humidity, airflow, and normality remain constant. A device that heats, adjusts airflow, and removes dust. Air conditioners use cooling (gas, liquid) that takes heat from the surroundings by “vaporization”, which changes from liquid to gas, and conversely, by “solidification”, where the refrigerant changes from gas to liquid. It is a system that uses heat dissipation that gives heat to the surroundings. In this system, cooling and heating are performed by efficiently pumping and moving heat in the atmosphere using a compressor (compressor). For this reason, the air conditioner consumes a large amount of power when the refrigerant is compressed by the compressor. This compressor consumes the most power among air conditioner devices.

  It is desirable for the air conditioner administrator to reduce the running cost of an office building or the like for the user of the air conditioner to reduce the power consumption of the air conditioner. Further, reduction of power consumption is desirable because it leads to reduction of CO2 emission from the viewpoint of the global environment. Here, “user” and “manager” for the air conditioner are defined. In a so-called tenant building, the owner (owner) of the building may bear the power cost consumed by the air conditioner of each tenant in a lump or may be borne by each tenant. In the former, the administrator is the owner of the building, and the user is each tenant. In the latter case, the administrator and the user are both tenants. If the company is distributed on each floor in an office building or a company that uses multiple air conditioners on one floor, the administrator is that company, and the user can be an employee on each floor or each air Become an employee who uses a harmony machine.

  The manager of the air conditioner may manage the usage status of the air conditioner for the user from the viewpoint of reducing the running cost of an office building or the like and reducing the CO2 emission amount. For example, the user may be requested to lower (or increase) the set temperature of the air conditioner in summer or winter, and may be requested to stop the air conditioner at night when there are few indoor users. .

  As a building management system for an office building or a facility management system for a factory, a management company may remotely monitor an air conditioner, output a monitoring result, and submit it to the air conditioner administrator. The monitoring results are collected operation data and failure data related to the air conditioner, and are generally submitted to the air conditioner manager as they are.

  On the other hand, Patent Document 1 discloses an operation monitoring system for air conditioning equipment. Patent Document 2 discloses an energy consumption control device and an energy consuming device.

  The air conditioner operation monitoring system disclosed in Patent Document 1 provides an air conditioner with an operation state monitoring function, and monitors normal / abnormal operation state information in the air conditioner such as cold / hot water shortage information. In this case, the recovery method according to the diagnosis result and the cost related to the recovery are grasped.

  The energy consumption control device and the energy consuming device disclosed in Patent Document 2 allow a user to select one operation mode from among a plurality of operation modes that determine the relative energy consumption of the energy consuming device. The user can execute the energy saving operation of the energy consuming device with his own intention while objectively grasping the degree of energy saving.

  Embodiments according to the present invention will be described below in detail with reference to the drawings.

  FIG. 1 shows a schematic configuration of an embodiment of an air conditioner usage status diagnosis apparatus. The air conditioner usage status diagnosis apparatus 1 includes an operation information measurement unit 2, a temperature information measurement unit 3, an air conditioning information storage unit 4, a usage status diagnosis unit 5, and a usage status display unit 6.

  The operation information measurement unit 2 measures data related to the operation state of the air conditioner 10. The data relating to this operating state includes the set temperature of the air conditioner 10, the time during which the so-called thermostat 13 is turned on, which means the time during which the thermostat 13 is ON, and the operating time of the air conditioner 10. It is. These data are basic data according to the present invention, and besides this, for example, the operation time of a compressor (not shown) may be included. These data are measured by measuring instruments such as timers 11 attached to the air conditioner 10. The operation information measuring unit 2 collects data from each measuring instrument attached to the air conditioner 10 and measures an average value and an integrated value for each fixed time such as month or day from these data. Then, the driving information measurement unit 2 transmits these data to the usage status diagnosis unit 5, and the usage status diagnosis unit 5 stores these data in the air conditioning information storage unit 4.

  The temperature information measuring unit 3 measures data related to the temperature of the room. In the present embodiment, this data is the suction temperature by the temperature sensor 12 attached in the vicinity of the air suction port of the air conditioner 10. In addition to the suction temperature, the temperature of a specific place in the room or the outdoor temperature may be included. The operation information measuring unit 2 collects temperature data from a temperature sensor 12 attached to the air conditioner 10 and measures an average value or an integrated value for each fixed time such as month or day from these temperature data.

Then, the driving information measurement unit 2 transmits these data to the usage status diagnosis unit 5, and the usage status diagnosis unit 5 stores these data in the air conditioning information storage unit 4.

  The air conditioning information storage unit 4 stores data relating to the measured operating state of the air conditioner 10 and data relating to the temperature of the room, and serves as a database. In addition, as will be described later, a message about the usage status of the user of the air conditioner 10 is also stored.

  The usage status diagnosing unit 5 diagnoses the usage status of the user of the air conditioner 10 from the data stored in the air conditioning information storage unit 4. Further, the message stored in the air conditioning information storage unit 4 is selected. Hereinafter, an embodiment of diagnosis of the usage status diagnosis unit 5 will be described using a flowchart. Each step of each flowchart is denoted by S1, S2, S3.

  In FIG. 2, the flowchart of 1st Embodiment about the diagnosis of the use condition diagnostic part 5 is shown. The use condition diagnosis unit 5 diagnoses that the air conditioner 10 has been so-called unattended operation. Here, “unmanned operation” and “the air conditioner is operated in an unattended room” means that the air conditioner is operated even though there are few users. For example, most of the employees go out during work, and the remaining employees continue to operate without switching the temperature setting of the air conditioner 10, or because no one remains, the air conditioner 10 However, this is a case where the unmanned operation is performed at the set temperature. In addition, during the lunch break, most of the employees go out and the air conditioner 10 operates unattended. In the present embodiment, the accumulated operation time (ΣT1) of the air conditioner 10 and the accumulated time (ΣT2) when the thermostat 13 is ON are used as data. First, the operation time (T1) of the air conditioner 10 is measured (S1), and at the same time, the time (T2) when the thermostat 13 is ON is measured (S2). Next, the driving information measuring unit 2 accumulates the measurement results for a certain period (month) (S3). And the use condition diagnosis part 5 calculates the value of the time (ΣT2) / the integrated operation time (ΣT1) of the air conditioner 10 when the thermostat 13 is ON (S4). The calculated value is compared with the set value α (S5), and when the calculated value does not reach the set value α, it is determined that the operation load of the air conditioner 10 is extremely small, and Diagnose (S6). This is because the number of users is small, and even when the thermostat 13 is turned on, the heat load is extremely small, so that the automatic adjustment of the room temperature is easy and is immediately turned off. Therefore, as compared with the normal state, the time (ΣT2) during which the thermostat 13 is ON is extremely reduced. The value of α is set in advance from past experience values, theoretical values by simulation, and the like.

  When the use condition diagnosis unit 5 diagnoses that the air conditioner 10 has been operated unattended, as shown in FIG. 2, the operation load stored in the air conditioning information storage unit 4 seems to be extremely small. It is recommended to check if there is any "(S6). The usage status display unit 6 visually displays this message. Further, this message is transmitted to the manager of the air conditioner 10 together with the operation data of the air conditioner 10. With this message, the manager warns the user of the air conditioner 10 so as to pay attention to unmanned operation, or takes measures such as putting a warning message at the exit of the room. It becomes possible. If the use condition diagnosis unit 5 does not diagnose that the air conditioner 10 has been operated unattended, the use state diagnosis unit 5 selects the message “good operation” stored in the air conditioning information storage unit 4 (S7).

  In FIG. 3, the flowchart of 2nd Embodiment about the diagnosis of the use condition diagnostic part 5 is shown. The use condition diagnosis unit 5 diagnoses that the air conditioner 10 has been operated without forgetting to turn off the switch. For example, when the person who has left the room forgets to turn off the air conditioner 10 after the work ends, or when the air conditioner 10 operates overnight. In the present embodiment, the operation time (ΣT3) accumulated every day of the air conditioner 10 is used as data. First, the operation time (T3) of the air conditioner 10 is measured (S1). Next, the driving information measuring unit 2 integrates the measurement results every day for a certain period (month) (S2). Further, the usage status diagnosis unit 5 reads the set appropriate operation time (ΣT4) of the day stored in the air conditioning information storage unit 4 from the air conditioning information storage unit 4 (S3). Then, the integrated operation time (ΣT3) / appropriate operation time (ΣT4) is calculated for each day, and the number of days (n) exceeding 1.0 is counted (S4). The usage status diagnosis unit 5 compares the number of days (n) counted every month with the set value β (S5), and if the counted number of days (n) exceeds the set value β, the air conditioner 10 It is determined that the operation time is extremely long, and the use situation described above is diagnosed (S6). If the counted number of days (n) does not exceed the set value β, the message “good operation” stored in the air conditioning information storage unit 4 is selected (S7). Here, the value of β is set in advance from past experience values, theoretical values by simulation, and the like.

  In FIG. 4, the flowchart about the other Example of 2nd Embodiment about the diagnosis of the use condition diagnostic part 5 is shown. In this embodiment, the operation time (ΣT5) accumulated for each month of the air conditioner 10 is used as data. First, the operation time (T5) of the air conditioner 10 is measured (S1). And the driving information measurement part 2 integrates this measurement result for a fixed period (month) (S2). Next, the usage status diagnosis unit 5 reads the accumulated operation time (ΣT6) of the same month (for example, last year) stored in the air conditioning information storage unit 4 from the air conditioning information storage unit 4 (S3). Then, the accumulated operating time (ΣT5) / the past (last year) accumulated operating time (ΣT6) is calculated (S4). When the calculated value exceeds the set value γ, it is determined that the operation time of the air conditioner 10 is extremely long, and the above-described use state is diagnosed (S6). If the set value γ is not exceeded, the message “good operation” stored in the air conditioning information storage unit 4 is selected (S7). Here, the value of γ is set in advance from past experience values, theoretical values by simulation, and the like. Since the accumulated monthly operation time of the air conditioner 10 fluctuates seasonally, it is possible to improve the accuracy by comparing with the past performance in the same month. The past same month may be the previous year, or may be the average of the past multiple years.

  When the air conditioner 10 diagnoses that the air conditioner 10 has been operated without forgetting to turn off the switch, as shown in FIG. 3, the usage status diagnosis unit 5 stores the “operation time” stored in the air conditioning information storage unit 4. “There are more than XX days that exceed T4 time. We recommend that you check if you have forgotten to turn off the air conditioner.” Or, as shown in Fig. 4, "The operating time has increased by more than XX% compared to last year. We recommend that you check if you have forgotten to turn off the air conditioner." Select a message. The usage status display unit 6 visually displays this message. Further, this message is transmitted to the manager of the air conditioner 10 together with the operation data of the air conditioner 10. With this message, the administrator warns the user of the air conditioner 10 so as not to forget to turn it off, or puts a countermeasure such as putting a warning message at the exit of the room. Is possible.

  FIG. 5 shows a flowchart of the third embodiment regarding the diagnosis of the usage status diagnosis unit 5. The usage status diagnosis unit 5 diagnoses that the indoor heat load is high. The thermal load of this room varies depending on the usage state (number of users) of the users of the room and the number of heat sources such as lighting and personal computers. It is also affected by the room environment such as the area of the opening of the room. In the present embodiment, as data, the average set temperature (C1) of the air conditioner 10, the average suction temperature (C2), and the time (T7) when the thermostat 13 of the air conditioner 10 is ON are used. First, the set temperature (C1) and the suction temperature (C2) are measured (S1), and at the same time, the time (T7) during which the thermostat 13 is ON is measured (S2). Next, the driving information measuring unit 2 integrates the measurement results for a certain period (day) (S3). Further, the temperature information measuring unit 3 calculates an average set temperature (C3) and an average suction temperature (C4) (S4). Then, the use state diagnosis unit 5 calculates the difference between the average set temperature (C3) and the average suction temperature (C4), and compares the time (T7) when the thermostat is ON with the set time Δ (S4). ). The difference between the average set temperature (C3) and the average suction temperature (C4) is equal to or higher than the set temperature θ ° C., and the time (T7) when the thermostat is ON is equal to or higher than the set time Δ. If it is, it is determined that the heat load in the room is high, and the use situation described above is diagnosed (S6). If the air conditioner 10 does not diagnose that the indoor heat load is high, the message “good operation” stored in the air conditioning information storage unit 4 is selected (S7). Here, the values of θ ° C. and Δ are set in advance from past experience values, theoretical values by simulation, and the like.

  When the air conditioner 10 diagnoses that the indoor heat load is high, the usage condition diagnosis unit 5 stores “the indoor heat load seems to be high.” Stored in the air conditioning information storage unit 4. The efficiency of the air conditioner is improved, and an energy saving effect can be expected ”is selected (S6). The usage status display unit 6 visually displays this message. Further, this message is transmitted to the manager of the air conditioner 10 together with the operation data of the air conditioner 10. With this message, the administrator can take measures such as processing wasteful heat sources, installing curtains on windows, making window glass heat-absorbing glass, and applying a heat-absorbing film on window glass. .

  In FIG. 6, the flowchart of 4th Embodiment about the diagnosis of the use condition diagnostic part 5 is shown. The usage status diagnosis unit 5 diagnoses that the set temperature is not appropriate. For example, in this Embodiment, the average value (C6) of the preset temperature of the air conditioner 10 is used as data. First, the set temperature (C5) of the air conditioner 10 is measured (S1). Next, the temperature information measuring unit 3 integrates the measurement results for a certain period (month) (S2). The usage status diagnosis unit 5 calculates the average value (C6) of the set temperatures for each month (S3). Further, the usage status diagnosis unit 5 reads the appropriate set temperature (C7) stored in the air conditioning information storage unit 4 from the air conditioning information storage unit 4 (S4). The use state diagnosis unit 5 determines that the set temperature is not appropriate when the average value (C6) of the set temperature for each month is equal to or higher than (or lower than) the appropriate set temperature (C7), and is described above. The usage status is diagnosed (S6). When the air conditioner 10 diagnoses that the set temperature is appropriate, the message “good operation” stored in the air conditioning information storage unit 4 is selected (S7).

  When the air conditioner 10 diagnoses that the set temperature is not appropriate, the use state diagnosis unit 5 stores “the average set temperature is C7 ° C. or higher (or below) stored in the air conditioning information storage unit 4. The energy saving effect can be expected by setting the temperature appropriately. " The usage status display unit 6 visually displays this message.
