Description

  The present invention relates to a thermal diagnostic apparatus, a thermal diagnostic system, and a program for diagnosing a thermal environment of a target space in a building.

  In recent years, energy saving is required in various situations. The thermal environment is no exception, and air-conditioning equipment with low energy consumption has been developed and marketed.

  It is known that this thermal environment has a great influence not only on the performance of the air conditioning equipment but also on the performance of the building enclosure.

  For example, the reason why a large amount of heating energy is used in a building with low heat insulation properties is an increase in heat flow between the room and the outside due to low heat insulation, a cold draft generated near a cold wall surface, and the like. In the case of the cold draft, the air in the vicinity of the floor is cooled, and as a result, the number of heating operations of the air conditioning equipment increases by the user who feels uncomfortable. This tendency becomes more prominent as it approaches the spring when the outside cold weather becomes milder. For this reason, in a building with low thermal insulation, it becomes a lifestyle that relies on heating of air conditioning equipment until early spring.

  However, there is a limit to improving the performance of air conditioning equipment, and in order to further improve the thermal environment, it is necessary to improve the performance of the building frame.

  If you improve the performance of the building's enclosure, you can reduce the energy consumption of the air conditioning equipment, but changing the building's enclosure requires time and money, so you want to evaluate the energy usage in advance. The request was high.

  In response to such a request, Patent Document 1 discloses an energy evaluation technique for evaluating the energy consumption of an air conditioning facility used in a target space in a building where the thermal characteristics of structures such as walls, ceilings, and floors are inadequate. It is disclosed.

  The energy evaluation technique described in Patent Document 1 can estimate the amount of energy used after the countermeasure and compare the amount of energy used before and after the countermeasure when the target space is subjected to a heat insulation measure or the like. .

JP 2002-267235 A

  However, although the energy evaluation technique described in Patent Document 1 can evaluate the energy consumption of the air conditioning equipment, it cannot evaluate the operating rate of the air conditioning equipment.

  In order to accurately show energy conservation, it is necessary to evaluate the amount of energy used quantitatively. However, it is the operating rate rather than the energy usage that people in the target space actually feel energy conservation in their daily lives. There are often. In other words, the amount of energy used is difficult to understand unless it is quantified, but the operating rate, that is, the operating time, can be understood sensuously by looking at the operating status of the air conditioning equipment. For example, if the operation rate is lower than before, it is considered that people in the target space have achieved energy saving.

  When a thermal environment system with higher performance than the current state is introduced into a building, if the difference in operating rate and energy usage before and after the introduction can be presented in advance, it is motivated to introduce the thermal environment system. As a result, it can lead to the spread of high-quality buildings.

In addition, when a floor heating device is already provided, the thermal environment system with higher performance than the current state refers to a system configured with a floor heating device with higher heating performance than the current state.

  Hereinafter, embodiments will be described with reference to the drawings.

  As shown in FIG. 1, the thermal diagnostic system 1 according to the present embodiment includes a thermal diagnostic device 2 and a notification device 3.

  The air conditioning equipment 4 is arranged in a target space in the building. In addition, the air conditioning equipment 4 may be comprised by one air conditioning apparatus, and may be comprised by the several air conditioning apparatus.

  The thermal diagnostic apparatus 2 includes, for example, a computer (including a microcomputer) on which a CPU (Central Processing Unit) and a memory are mounted as main components. The thermal diagnostic apparatus 2 includes an acquisition unit 21, a first calculation unit 22, a threshold setting unit 23, a second calculation unit 24, a comparison unit 25, a third calculation unit 26, and a notification control unit 27. And. The thermal diagnosis apparatus 2 includes a device interface unit (hereinafter referred to as “device I / F unit”) 281 and a notification interface unit (hereinafter referred to as “notification I / F unit”) 282. Further, the thermal diagnostic apparatus 2 includes a first sensor interface (hereinafter referred to as “first sensor I / F unit”) 283 and a second sensor interface (hereinafter referred to as “second sensor I / F unit”) 284. And. In addition, the thermal diagnostic apparatus 2 includes a storage unit 29.

  The acquisition unit 21 acquires the operating rate of the air conditioning equipment 4. The acquisition unit 21 of the present embodiment includes an information acquisition unit 211 and an operation rate calculation unit 212.

  The information acquisition unit 211 acquires operation log information of the air conditioning equipment 4 from the air conditioning equipment 4. For example, the information acquisition unit 211 acquires, as the log information, a startup log of the air conditioning equipment 4 for a predetermined time (for example, AM 6 AM to AM 8 AM and PM 5 PM to PM 8 PM) for each month or each outside air temperature.

  By the way, an operating device 41 such as a manual remote controller (switch) is used for starting and stopping the air conditioning equipment 4.

  Therefore, the information acquisition unit 211 of the present embodiment acquires operation history information operated by the operation device 41, that is, operation history information for the air conditioning equipment 4 from the air conditioning equipment 4 as log information. Since the operation device 41 is operated when a person in the target space feels hot or cold, it is considered that the operation history indicates a response to the thermal sensation, It leads to estimation of energy saving effect.

  The operation rate calculation unit 212 calculates the operation rate of the air conditioning equipment 4 using the log information acquired by the information acquisition unit 211.

  The first calculation unit 22 uses the building information about the building and the facility information about the air conditioning equipment 4 to calculate the amount of energy used when the air conditioning equipment 4 operates at the operating rate acquired by the acquisition unit 21. The 1st calculation part 22 of this embodiment calculates the electric power usage amount when the air-conditioning equipment 4 operate | moves with the said operation rate as energy usage-amount.

  The 1st calculation part 22 of this embodiment calculates energy usage using a commercially available energy simulation. And the 1st calculation part 22 calculates a period energy use amount by the product sum of the monthly estimated energy usage amount computed from the said energy simulation, the estimated operation rate of the monthly air-conditioning equipment 4, and the monthly occurrence frequency. calculate.

  The energy simulation used in the first calculation unit 22 is, for example, HASP, SMASH, EnergyPlus, or the like. As shown in FIG. 2, the heat load amount and the power usage amount can be calculated by inputting the building information, the facility information, and the operation information. The building information is, for example, floor plan, direction, heat insulation, and the like. The facility information is information related to the air conditioning facility 4 such as an operation rate. The operation information is, for example, a schedule of the air conditioning equipment 4, a occupancy schedule, and the like.

  The threshold setting unit 23 illustrated in FIG. 1 sets the estimated operating rate of the air conditioning equipment 4 when a thermal environment system with higher performance than the current state is introduced into a building as a threshold. The threshold value setting unit 23 of the present embodiment acquires, for example, an operation rate obtained from a high-performance building (high heat insulation + air conditioning equipment) from the external device (not shown) as the estimated operation rate. The external device collects and stores the results of operating rates obtained in various buildings in advance. The threshold setting unit 23 obtains the operation rate obtained in the building having the target space and the high-performance building to be compared from the information stored in the external device.

  The second calculation unit 24 uses the building information about the building and the facility information about the air conditioning equipment 4 (such as the estimated operating rate) to calculate the estimated energy usage when the air conditioning facility 4 operates at the estimated operating rate. .

  The second calculator 24 of the present embodiment calculates the estimated energy usage using a commercially available energy simulation or the like. And the 2nd calculation part 24 calculates | requires a period energy usage amount by the product sum of the monthly estimated energy usage amount computed from the said energy simulation, the estimated operation rate of the monthly air-conditioning equipment 4, and the monthly occurrence frequency. calculate. In the present embodiment, the energy simulation used by the second calculation unit 24 is the same as the simulation used by the first calculation unit 22.

  By the way, in the energy simulation, an accurate operation schedule (see FIG. 3) of the air conditioning equipment 4 cannot be obtained, but the shortcoming can be compensated by the operation history (log information) of the air conditioning equipment 4. However, it is difficult to predict by using the above log information about morning and evening heating operation refusal due to the introduction of a thermal environment system with higher performance than the current state to improve the thermal insulation of the building.

  Therefore, the second calculation unit 24 performs energy simulation on the assumption that the operation rate of the air conditioning equipment 4 in each month coincides with the operation rate in a highly insulated building due to the high heat insulation of the building, and uses estimated energy. Calculate the amount.

  The comparison unit 25 compares the operation rate calculated by the operation rate calculation unit 212 of the acquisition unit 21 with the threshold set by the threshold setting unit 23. That is, the comparison unit 25 compares the current operation rate with the estimated operation rate.

  The third calculation unit 26 calculates a difference energy usage amount obtained by subtracting the estimated energy usage amount from the energy usage amount when the operation rate is higher than the threshold value. That is, the third calculation unit 26 compares the energy usage calculated by the first calculation unit 22 with the estimated energy usage calculated by the second calculation unit 24, and calculates the amount of energy used for the period. The difference is calculated as an energy saving effect.

  The notification control unit 27 controls the notification device 3 so as to notify the comparison result of the comparison unit 25 (the magnitude relationship between the operation rate and the estimated operation rate) and the difference energy usage amount.

  The notification device 3 is connected to the notification I / F unit 282, and notifies the comparison result of the comparison unit 25 and the difference energy usage amount under the control of the notification control unit 27. As shown in FIG. 4, the notification device 3 notifies the operation rate of each month as a comparison result of the comparison unit 25. 4A shows the operation rate in the target space (house), and FIG. 4B shows the operation rate in the high-performance building (house), that is, the thermal environment system with higher performance than the current state in the target space. The estimated operating rate when introducing is used. Moreover, C of FIG. 4 shows the operation rate in a low-performance building (house) as a reference example, that is, the estimated operation rate when a thermal environment system having a lower performance than the current state is introduced into the target space. FIG. 4D shows the average outside air temperature. The notification means of the notification device 3 may be a display, an audio output, both a display and an audio output, or other means.

  By the way, in this embodiment, the threshold value that is the comparison target of the operating rate of the air conditioning equipment 4 varies depending on the temperature outside the target space, that is, the outside air temperature. The temperature sensor 6 is connected to the first sensor I / F unit 283. The temperature sensor 6 is installed outside the target space and measures the outside air temperature. The threshold setting unit 23 changes the threshold according to the outside air temperature measured by the temperature sensor 6.

  In addition, the thermal diagnosis apparatus 2 not only notifies the comparison result (the magnitude relationship between the operation rate and the estimated operation rate) and the difference energy usage of the comparison unit 25 for each month but also for each outside air temperature. 3 can be controlled.

  In this case, the thermal diagnostic apparatus 2 performs an energy simulation for each outside air temperature, and calculates an energy usage amount for each outside air temperature. The notification device 3 notifies the comparison result of the comparison unit 25 and the difference energy usage amount for each outside air temperature under the control of the notification control unit 27. As a comparison result of the comparison unit 25, the notification device 3 notifies the operation rate for each outside air temperature as shown in FIG. 5A shows the operation rate in the target space (house), and FIG. 5B shows the operation rate in a high-performance building (house), that is, a thermal environment system with higher performance than the current state in the target space. The estimated operating rate when introducing is used. Moreover, C of FIG. 5 shows the operation rate in a low-performance building (house) as a reference example, that is, the estimated operation rate when a thermal environment system with a lower performance than the current state is introduced into the target space.

  From the characteristics of the operating rate shown in FIG. 5, it can be assumed that the operating rate at the outside air temperature T1 in the morning and evening has changed from S1 to S2 (<S1) in FIG. Calculate the differential energy usage for the entire period based on changes in availability. As shown in FIG. 5, by reporting the operating rate according to the outside air temperature, it is possible to correct a difference in season or region, and it is possible to improve the estimation accuracy of the energy saving effect.

  By the way, since the operating rate of the air conditioning equipment 4 is based on the ratio of operating the air conditioning equipment 4 on the day when the user is in the room, the assumption is broken if the office is often absent on a business trip or the like. For this reason, it is difficult to calculate the operating rate of the air conditioning equipment 4 correctly.

  Therefore, in order to avoid using the data on the days of absence in the estimation of the operating rate of the air conditioning equipment 4 in conjunction with the action schedule of people entering and leaving the target space, the thermal diagnosis apparatus 2 of the present embodiment is A schedule setting unit 51 is provided.

  The schedule setting unit 51 sets an action schedule for people entering and leaving the target space. The schedule setting unit 51 receives an input of a day in the morning / evening, for example. The information acquisition unit 211 acquires the action schedule set by the schedule setting unit 51. Then, based on the action schedule acquired by the information acquisition unit 211, the operation rate calculation unit 212 determines the occupancy date as a period for calculating the operation rate, and calculates the operation rate based on the period. calculate. Thus, the estimation accuracy of the operating rate can be increased by inputting in advance the action schedule of people entering and leaving the target space.

  By the way, in view of the fact that an action schedule is not always input correctly when an action schedule is input, the schedule setting unit 51 is provided with a human sensor (person detection means) 7 that detects a person in the target space. An action schedule may be set based on the detection result. The schedule setting unit 51 accumulates morning and evening occupancy states as log information by the human sensor 7 and uses them as schedule information. Thereby, the precision of an action schedule can be raised.

  The human sensor 7 is, for example, a heat ray sensor (pyroelectric infrared sensor) that detects a heat ray emitted from the human body, and is connected to the second sensor I / F unit 284. When the human sensor 7 detects a person existing in the target space, the human sensor 7 outputs a detection signal indicating that the person has been detected, that is, a detection result, to the schedule setting unit 51.

  Moreover, the thermal diagnostic apparatus 2 of the present embodiment includes a pattern setting unit 52 that sets a lifestyle pattern of a person entering and exiting the target space. Examples of lifestyle patterns include working together, family composition, night type, and morning type. Then, the threshold setting unit 23 sets a threshold according to the lifestyle pattern set by the pattern setting unit 52. That is, a threshold is prepared for each life pattern (co-working, family structure, night type / morning type). By inputting a life pattern of a person who enters and exits the target space, the threshold setting unit 23 changes to a threshold corresponding to the life pattern. As a result, the estimation accuracy of the energy saving effect can be increased.

  By the way, in view of the fact that a life pattern is not always input correctly when inputting a life pattern, the pattern setting unit 52 is a human sensor (person detection means) 7 for detecting a person in the target space. A lifestyle pattern may be set based on the detection result. Thereby, the precision of a life pattern can be improved. When the human sensor 7 detects a person existing in the target space, the human sensor 7 outputs a detection signal to the pattern setting unit 52.

  The storage unit 29 stores a program for the thermal diagnostic apparatus (computer) 2 to execute various functions. That is, the storage unit 29 includes the thermal diagnostic apparatus 2 as the acquisition unit 21, the first calculation unit 22, the threshold setting unit 23, the second calculation unit 24, the comparison unit 25, the third calculation unit 26, and the notification control unit 27. The program for functioning as the schedule setting part 51 and the pattern setting part 52 is stored. The program is stored in advance in the storage unit 29 when the thermal diagnostic apparatus 2 is shipped. However, when the thermal diagnostic apparatus 2 acquires the program after shipment, as an example of a technique for the thermal diagnostic apparatus 2 to acquire the program, there is a technique using a computer-readable recording medium in which the program is recorded. In the case of the method using the recording medium, the thermal diagnostic apparatus 2 only needs to include a reading device (not shown) for reading data on the recording medium. Examples of the recording medium include an optical disk and a memory card. Examples of the reading device include a drive device that reads information on an optical disk, and a memory card reader that reads information on a memory card. Further, as another method for the thermal diagnostic apparatus 2 to acquire the program, there is a method for downloading the program from another device (for example, a server) using a network. In the case of the method of downloading the program, the thermal diagnosis apparatus 2 only needs to have a communication function for communicating with other apparatuses using a network.

  Next, the operation of the thermal diagnostic apparatus 2 according to the present embodiment will be described with reference to FIG. First, the information acquisition unit 211 and the threshold setting unit 23 of the acquisition unit 21 acquire necessary information (S1). Necessary information is an operation history of the air conditioner 4, an outside air temperature, an action schedule, and a life pattern. Thereafter, the operation rate calculation unit 212 of the acquisition unit 21 calculates the operation rate of the air conditioning equipment 4 using the operation history and action schedule of the air conditioning equipment 4 (S2). Then, the 1st calculation part 22 calculates the energy usage amount when the air-conditioning equipment 4 operate | moves with the operation rate calculated by the operation rate calculation part 212 of the acquisition part 21 (S3). In addition, the threshold setting unit 23 reads the operating rate of the air conditioning equipment in the high-performance building, changes the operating rate using the outside air temperature, the action schedule, and the life pattern, and heats the target space with higher performance than the current state. A threshold is set as the estimated operating rate of the air conditioning equipment 4 when the environmental system is introduced (S4). Then, the 2nd calculation part 24 calculates the estimated energy usage amount when the air-conditioning equipment 4 operate | moves with the threshold value (S5). Thereafter, the comparison unit 25 compares the operating rate with a threshold value (S6). Thereafter, when the operating rate is higher than the threshold (in the case of “Yes” in S6), the third calculation unit 26 calculates a difference energy usage amount obtained by subtracting the estimated energy usage amount from the energy usage amount (S7). Thereafter, the notification control unit 27 controls the notification device 3 so as to notify the comparison result of the comparison unit 25 and the difference energy usage amount (S8). On the other hand, when the operation rate is equal to or less than the threshold (in the case of “No” in S6), the notification control unit 27 controls the notification device 3 so as to notify the comparison result of the comparison unit 25 (S9).

  In the thermal diagnostic system 1 of the present embodiment described above, the thermal diagnostic apparatus 2 introduces the current operating rate of the air conditioning equipment 4 in the target space in the building and a thermal environment system with higher performance than the current state in the building. The estimated operating rate (threshold value) of the air conditioning equipment 4 is compared. When the operating rate is higher than the threshold value, the thermal diagnostic apparatus 2 calculates the current energy usage amount and the estimated energy usage amount when a thermal environment system with higher performance than the current state is introduced into the building. Then, the thermal diagnostic apparatus 2 calculates a difference energy usage amount obtained by subtracting the estimated energy usage amount from the current energy usage amount. Furthermore, the thermal diagnostic apparatus 2 according to the present embodiment causes the notification apparatus 3 to notify the comparison result of the operation rate and the difference energy usage amount. Thereby, in the thermal diagnostic apparatus 2 of the present embodiment, quantitatively evaluate the improvement effect of the operating rate and the energy usage amount, that is, the improvement effect of the thermal environment when the thermal environment system is introduced into the building having the target space. Can do. As a result, energy-saving proposals suitable for the target space can be made, leading to the spread of high-quality buildings. That is, the performance difference between the current thermal environment system and the high-performance thermal environment system can be clarified.

  Moreover, in the thermal diagnostic system 1 of this embodiment, the thermal diagnostic apparatus 2 sets a threshold value for each outdoor temperature that is deeply related to the season. Thereby, in the thermal diagnostic apparatus 2 of this embodiment, the precision of the energy use amount, ie, the improvement effect of a thermal environment, can be improved compared with the case where a threshold value is constant irrespective of outside temperature.

  Furthermore, in the thermal diagnostic system 1 of the present embodiment, the thermal diagnostic apparatus 2 calculates an operating rate using an operation history deeply related to a reaction of a person in the target space to the thermal environment. Thereby, in the thermal diagnostic apparatus 2 of this embodiment, energy consumption can be calculated with comparatively high precision.

  Moreover, in the thermal diagnostic system 1 of this embodiment, the thermal diagnostic apparatus 2 determines the period during which the operating rate is calculated in consideration of different behavior schedules depending on the person entering and exiting the target space. Thereby, in the thermal diagnostic apparatus 2 of this embodiment, since the energy usage can be calculated using the operation rate based on the period, the energy usage can be compared with the case where the action schedule is not considered. Accuracy can be increased.

  At this time, the thermal diagnostic apparatus 2 may set an action schedule based on a detection result of a person in the target space. Thereby, in the thermal diagnostic apparatus 2 of this embodiment, the effort of an input can be saved when setting an action schedule.

  Moreover, in the thermal diagnostic system 1 of this embodiment, the thermal diagnostic apparatus 2 changes a threshold value in consideration of a different life pattern depending on a person entering and exiting the target space. Thereby, in the thermal diagnostic apparatus 2 of this embodiment, the precision of the energy use amount, ie, the improvement effect of a thermal environment, can be improved compared with the case where a lifestyle pattern is not considered.

  At this time, the thermal diagnostic apparatus 2 may set a lifestyle pattern based on the detection result of the person in the target space. Thereby, in the thermal diagnostic apparatus 2 of this embodiment, when setting a lifestyle pattern, the effort of an input can be saved.

  In this embodiment, as a method for the acquisition unit 21 to acquire the operation rate, the information acquisition unit 211 acquires necessary information, and the operation rate calculation unit 212 calculates the operation rate using the necessary information.
