Description

[Technical field]

[0001] The present invention relates to an air conditioning capacity determination system, an air conditioning capacity determination method, and a program. [Background technology]

[0002] Conventionally, there have been two main methods used to calculate whether a building's air conditioning capacity meets the standards.

[0003] The first method is a method of calculating the maximum load of the air conditioning capacity by performing a steady-state calculation using the thermal insulation performance value of the building. The thermal insulation performance value of the building can be obtained by calculating the average heat transmission coefficient of the outer shell, for example, as shown in Patent Document 1. Although this first method can easily calculate the maximum load of the air conditioning capacity, it does not take into account the time history value including the heat capacity of each space in the building, but only uses one representative value. For this reason, there is a problem that the accuracy of the judgment is low, and it is easy to judge that the air conditioning capacity required is higher than the capacity actually required.

[0004] The second method is to simulate the thermal environment of a building using a thermal environment simulation program, etc. Specifically, the floor area of ​​the building, the area of ​​openings, the capacity of the air conditioning equipment of the building, the use schedule and occupancy schedule of the air conditioning equipment and heating equipment, information on the area division in which the building is built, etc. are used as input conditions, and a thermal environment simulation program such as AE-Sim / Heat (registered trademark) is executed. This makes it possible to obtain various simulation results of the thermal environment, including time history data of the heat load of each space in the building.

[0005] This second method provides very accurate results because it can obtain time history data on the heat load of each space in the building, but there are problems with using such a thermal environment simulation program, such as the cost, effort, and time required.

[0013] (overview) The present disclosure relates to an air conditioning capacity determination system, an air conditioning capacity determination method, and a program. More specifically, the present disclosure relates to an air conditioning capacity determination system, an air conditioning capacity determination method, and a program that can accurately determine whether the air conditioning capacity of a building having an air conditioning system satisfies a standard while minimizing cost, effort, and time.

[0014] In addition, the air conditioning capacity determination system, air conditioning capacity determination method, and program disclosed herein are suitable for use in determining the pass / fail of air conditioning capacity in buildings having air conditioning equipment, particularly in buildings using a so-called central air conditioning system that has one or a small number of heat source units.

[0015] (detail) An air conditioning capacity determination system, an air conditioning capacity determination method, and a program according to an embodiment of the present disclosure will be described in detail below with reference to Figures 1 to 4. First, an example of a building that is a determination target of the air conditioning capacity determination system and the air conditioning capacity determination method of the present disclosure will be described.

[0016] (1) Building As shown in FIG. 1, a building 1 has a roof 11 (or ceiling 12), an exterior wall 13, a floor 14 (or foundation 15), and an opening 16, which are parts related to the heat insulating performance of the outer shell. The building 1 has a two-story structure, and each floor has a plurality of rooms 18 separated by partitions 17. In the example shown in FIG. 2, rooms 181, 182, and 183 are formed on the first floor, and rooms 184, 185, and 186 are formed on the second floor. The building 1 also has a underfloor space 19 below the floor 14 on the first floor. An intake 191 is formed in the exterior wall 13 or foundation 15 to take in outside air from outside the building 1 into the underfloor space 19.

[0017] The upper surface of the exterior skin, which forms the thermal boundary between the inside and outside of the building 1, is made up of the roof 11 (or ceiling 12) excluding openings 16. The side surface of the exterior skin, which forms the thermal boundary between the inside and outside of the building 1, is made up of the exterior wall 13 excluding openings 16. The lower surface of the exterior skin, which forms the thermal boundary between the inside and outside of the building 1, is made up of the floor 14 (or foundation 15). The openings 16 are made up of entrances, windows, skylights, etc.

[0018] (2)Air conditioning equipment 1 and 2, a building 1 has an air conditioning system 2. The air conditioning system 2 has a heat source unit 21, a plurality of transport paths 22, a plurality of opening degree adjustment units 23, an air conditioning control unit 24, and an air conditioning input unit 25.

[0019] The heat source unit 21 can generate hot air having a temperature higher than the outside air temperature or cold air having a temperature lower than the outside air temperature. In this embodiment, the air conditioning equipment 2 is equipped with a so-called heat pump system, and the heat source unit 21 has a so-called indoor unit in the heat pump system. Although not shown, the so-called outdoor unit in the heat pump system is installed outside the building 1. The air conditioning equipment 2 is not limited to being equipped with a heat pump system. For example, the air conditioning equipment 2 may be one that generates hot air using gas as fuel.

[0020] One or a few heat source units 21 are provided in the air conditioning equipment 2, but are not provided for each room 18 in the building 1. In other words, the air conditioning equipment 2 in this embodiment constitutes a so-called whole-building air conditioning system that has only one or a few heat source units 21 and performs air conditioning for all necessary rooms 18 in the building 1.

[0021] The transport path 22 transports hot or cold air from the heat source 21. In this embodiment, the transport path 22 is configured with a duct or pipe (hereinafter simply referred to as a duct). A plurality of transport paths 22 are provided since the transport path 22 transports hot or cold air from one or a small number of heat source parts 21 to a large number of rooms 18 that require air conditioning. The upstream end of the transport path 22, which is connected to the heat source part 21, is configured with one or a small number of ducts (one in this embodiment), and branches toward the downstream side, and the end portions become the transport path 22 connected to each room 18. The downstream end of the transport path 22 is connected to the room 18 so as to lead into the room 18, and the opening at the downstream end becomes the air outlet 26.

[0022] In this embodiment, a filter 27 is provided in the duct immediately downstream of the heat source unit 21. Furthermore, the duct branches into a duct for the first floor and a duct for the second floor immediately downstream of the filter 27, and the duct for the first floor is provided with a first floor fan 281 as a blower 28, while the duct for the second floor is provided with a second floor fan 282. The transport paths 22 toward each room 18 on the first floor branch off downstream of the first floor fan 281 in the duct for the first floor, and the transport paths 22 toward each room 18 on the second floor branch off downstream of the second floor fan 282 in the duct for the second floor.

[0023] In addition, an underfloor fan 283 is provided in the underfloor space 19 as the air blower 28. An outside air intake passage 20 is formed which leads to the heat source unit 21 via the intake port 191 and the underfloor space 19. The underfloor fan 283 makes it possible to adjust the amount of outside air taken into the heat source unit 21 via the intake port 191 and the underfloor space 19, and to switch between taking in and stopping the outside air intake.

[0024] The opening degree adjustment unit 23 is basically provided for each transport path 22 and adjusts the opening degree of the transport path 22. The opening degree adjustment unit 23 includes opening degree adjustment units 231 to 236 provided in the transport paths 22 leading to the rooms 181 to 186, respectively. In this embodiment, the opening degree adjustment unit 23 is configured by a so-called VAV (Variable Air Volume) damper. The opening degree adjustment unit 23 can fully open or fully close the transport path 22. The opening degree adjustment unit 23 can continuously change the opening degree of the transport path 22 between fully open and fully closed.

[0025] It is not necessary to provide the opening degree adjustment unit 23 for all of the conveying paths 22. Also, the opening degree adjustment unit 23 does not have to be configured by a VAV damper. For example, the opening degree adjustment unit 23 may change the opening degree of the conveying path 22 to a predetermined one-step opening degree between fully open and fully closed, or may change the opening degree stepwise to a plurality of steps.

[0026] The air conditioning control unit 24 controls the heat source unit 21, the opening degree adjustment unit 23, and the blower 28. In this embodiment, the air conditioning control unit 24 is configured by a computer system including, for example, one or more processors (microprocessors) and one or more memories. The air conditioning control unit 24 transmits control signals to the heat source unit 21, the opening degree adjustment unit 23, and the blower 28 via wired or wireless communication. One air conditioning control unit 24 is provided for each building 1.

[0027] The air conditioning control unit 24 is not limited to being configured by a computer system including one or more processors (microprocessors) and one or more memories. Also, the air conditioning control unit 24 may not be provided only one per building 1, but may be provided multiple times.

[0028] The air conditioning input unit 25 inputs commands to the air conditioning control unit 24. In this embodiment, the air conditioning input unit 25 is a so-called touch panel type input device, and transmits input command data to the air conditioning control unit 24 by wire or wirelessly. The installer needs to input, via the air conditioning input unit 25, which of the actually installed opening degree adjustment units 231 to 236 corresponds to the six opening degree adjustment units controlled by the air conditioning control unit 24 on the program. The installer can also input, as appropriate, via the air conditioning input unit 25, settings for controlling the set temperature of each room 18, the heat source unit 21, and the blower 28.

[0029] The air conditioning equipment 2 also has a room temperature measuring unit 29. The room temperature measuring unit 29 is installed in each room 18 that requires air conditioning. The room temperature measuring unit 29 has a temperature detection element such as a thermistor, and transmits the acquired data on the temperature of the room 18 to the air conditioning control unit 24 via wired or wireless communication.

[0030] (3) Air conditioning capacity determination system Next, the air conditioning capacity determination system 3 will be described. As shown in Fig. 3, the air conditioning capacity determination system 3 includes a storage unit 31, an acquisition unit 32, a determination condition calculation unit 33, a determination unit 34, and an output unit 35. The air conditioning capacity determination system 3 has a control circuit that executes an air conditioning capacity determination method described below. The air conditioning capacity determination system 3 can be realized, for example, by a computer system including one or more processors (microprocessors) and one or more memories. In other words, the air conditioning capacity determination system 3 functions as the air conditioning capacity determination system 3 by the one or more processors executing one or more (computer) programs (applications) stored in one or more memories.

[0031] The storage unit 31 stores in advance basic conditions including analysis results obtained by an analysis that outputs at least time history data of heat load for each area division (hereinafter referred to as "time history heat load analysis"). The storage unit 31 is configured, for example, with an EEPROM (Electrically Erasable Programmable Read Only Memory), but is not limited to an EEPROM.

[0032] One or a small number of building models are prepared, and serve as the basis for determining the judgment conditions for the building 1 to be judged. The building model has, for example, a specified external shape, a specified number of floors, specified openings, a specified outer skin (specified thermal insulation performance), and a specified air conditioning capacity. For this building model, analysis results are obtained by performing a time history heat load analysis for each regional division. Here, a regional division is a grouping of each point into several area divisions, and representative values ​​such as sunrise and sunset times by season (date), the direction and altitude of the sun at each hour, and the temperature at each hour are used for each regional division.

[0033] In this embodiment, the time history heat load analysis is performed by executing a thermal environment simulation program consisting of AE-Sim / Heat (registered trademark). Input conditions for the time history heat load analysis include the floor area and opening area of ​​the building model, the capacity of the air conditioning equipment of the building model, the use schedule and occupancy schedule of the air conditioning equipment and heating equipment, and information on the area division in which the building model is built. As a result, various thermal environment simulation results, including time history data of the heat load of each space in the building model, are obtained, and the necessary data are stored in the storage unit 31 as basic conditions. As the basic conditions, the time history data of the heat load of each space in the building model obtained by the time history heat load analysis may be stored in the storage unit 31 as it is. In addition, in order to reduce the load on the storage unit 31, information including peak value information of the time history temperature data obtained by the time history heat load analysis for the building model may be stored in the storage unit 31 as the basic conditions.

[0034] The acquisition unit 32 acquires input conditions including the floor area, opening area, capacity of the air conditioning equipment 2 of the building 1 to be evaluated, information on the area classification in which the building 1 is built, and information on the direction in which the opening 16 of the building 1 to be evaluated faces. The acquisition unit 32 has an interface 321 with an external storage device 36, and can acquire the input conditions from the external storage device 36. The acquisition unit 32 can also acquire the input conditions from an input device 37 such as a mouse or keyboard. The acquisition unit 32 can also acquire the input conditions from both the external storage device 36 and the input device 37.

[0035] As a specific example of input conditions, A The input conditions are, but are not limited to, the value of ηAc, the area of ​​the exterior wall 13, the total floor area, the first floor ceiling height, the second floor ceiling height, the floor area of ​​each room 18, the area of ​​the opening 16 (the height and width of the opening 16), the direction in which the opening 16 faces, etc. Furthermore, as an input condition, a unique room number may be assigned to each room 18. Furthermore, as an input condition, the projection dimension of the eaves part that projects above the exterior wall 13 on the upper side of the opening 16 may be input. The height and width of the opening 16 and the projection dimension of the eaves part make it possible to take into account the effect of shading the opening 16 against solar radiation.

[0036] The judgment condition calculation unit 33 calculates the judgment condition based on the basic condition according to the acquired input condition. That is, the judgment condition calculation unit 33 generates the judgment condition for the building 1 to be judged from the acquired input condition and the basic condition previously stored in the storage unit 31. The judgment conditions for heating are the peak value of the amount of heat (W) per unit time required in the building 1 to be judged in the heating season and the capacity (W) of the air conditioning equipment 2. If the peak value is equal to or less than the capacity of the air conditioning equipment 2, the pass / fail judgment result is "pass", and if the peak value exceeds the capacity of the air conditioning equipment 2, the pass / fail judgment result is "fail". Similarly, for cooling, the judgment conditions are the peak value of the amount of heat (energy) per unit time required in the building 1 to be judged in the cooling season and the capacity of the air conditioning equipment 2, if the peak value is equal to or less than the capacity of the air conditioning equipment 2, the pass / fail judgment result is "pass", and if the peak value exceeds the capacity of the air conditioning equipment 2, the pass / fail judgment result is "fail".

[0037] In generating judgment conditions, for example, the floor area, opening area, capacity of the air conditioning equipment 2 possessed by the building 1, the direction in which the openings 16 of the building 1 to be judged face, etc. of the building 1 to be judged are compared with the floor area, opening area, capacity of the air conditioning equipment of the building model, the direction in which the openings of the building model face, etc. of the building model, and these are multiplied by a coefficient calculated according to the difference between the two, etc. or a coefficient calculated from a predetermined table according to the difference between the two, etc. to correct the basic conditions, thereby generating judgment conditions.

[0038] As an example of generating the judgment condition, for example, the total area of ​​the outer shell including the opening and the average outer shell heat transfer coefficient (U A value), the total envelope area of ​​the building model and U A The product of the values ​​(which is the product of the building model), the total envelope area of ​​the building 1 to be judged, and U A The peak value of energy required per unit time in building 1 to be judged during the heating or cooling season is corrected by multiplying the peak value of energy required per unit time in the building model during the same period by (the product of building 1 / the product of the building model).

[0039] By performing such correction for each element (floor area, direction of opening, etc.), the peak value is corrected and the judgment condition is generated. Note that the correction method differs for each element.

[0040] The judgment unit 34 judges whether the judgment conditions satisfy the judgment criteria or not. As the judgment criteria, for example, a criterion is set as to whether the time history data of the heat load of each space in the building 1, which is estimated from the judgment conditions obtained by modifying the basic conditions, or the peak value representing the heat load of each space in the building 1, is within an allowable range from the set temperature of the air conditioning equipment 2. That is, in this example, the peak value itself of the time history temperature data obtained by the time history heat load analysis for the building model is used as the basic condition.

[0041] The allowable range is set as a deviation from the set temperature within, for example, 2° C., but the deviation is not limited to 2° C. In addition, the basic condition does not have to be the peak value obtained by the time history heat load analysis of the building model, and any value including some information on the peak value, such as a value obtained by multiplying the peak value by a coefficient, can be suitably used.

[0042] In addition, as peak values ​​representing the heat load of each space within building 1, for example, in the summer, the heat load of each space between 3:00 p.m. and 6:00 p.m., when the outside temperature is highest, is preferably used, and in the winter, the heat load of each space between 4:00 a.m. and 6:00 a.m. just before sunrise, when the outside temperature is lowest, is preferably used, but the values ​​are not limited to these time periods.

[0043] The output unit 35 outputs the pass / fail judgment result from the judgment unit 34. The output unit 35 has an interface 351 with an output device 38 such as a display, and can output the pass / fail judgment result to the output device 38.

[0044] (4) Air conditioning capacity determination method Next, the air conditioning capacity determination method will be described with reference to Fig. 4. The air conditioning capacity determination method includes a storage step, an acquisition step, a determination condition calculation step, a determination step, and an output step.

[0045] The storage step (step S1) is executed by the storage unit 31. The storage step is a step of storing basic conditions including analysis results obtained by a time history thermal load analysis for each area division of a building model.

[0046] The acquisition step (step S2) is executed by the acquisition unit 32. The acquisition step is a step of acquiring input conditions including the floor area of ​​the building 1 to be determined, the opening area, the capacity of the air conditioning equipment 2 of the building 1, and information on the area division in which the building 1 is to be built.

[0047] The judgment condition calculation step (step S3) is executed by the judgment condition calculation unit 33. The judgment condition calculation step is a step of calculating the judgment condition based on the basic condition in response to the acquired input condition.

[0048] The determination step (step S4) is executed by the determination unit 34. The determination step is a step for determining whether the determination condition satisfies the determination criterion or not.

[0049] The output step (step S5) is executed by the output unit 35. The output step is a step of outputting the pass / fail judgment result in the judgment step.

[0050] Further, in this embodiment, the output step outputs the input items to be input from the air conditioning input unit 25 for identifying the opening degree adjustment unit 23 for each of the multiple opening degree adjustment units 23. The output unit 35 outputs the input items to be input from the air conditioning input unit 25 for identifying the opening degree adjustment unit 23 for each of the multiple opening degree adjustment units 23. As described above, the input items to be input from the air conditioning input unit 25 for identifying the opening degree adjustment unit 23 are items for inputting from the air conditioning input unit 25 which of the multiple opening degree adjustment units actually installed corresponds to a plurality of opening degree adjustment units, for example, 10 to 14 (6 in the example of FIG. 4), controlled by the air conditioning control unit 24 on the program. The number is not limited. This makes it possible to suppress input errors when the installer inputs the input items to be input from the air conditioning input unit 25 for identifying the opening degree adjustment unit 23 for each of the multiple opening degree adjustment units 23.

[0051] Further, in this embodiment, the output step outputs proposal information for reducing the area of ​​the opening 16 in a predetermined direction when the pass / fail judgment result is negative. The output unit 35 outputs proposal information for reducing the area of ​​the opening 16 in a predetermined direction when the pass / fail judgment result is negative. The predetermined direction is preferably, for example, south, southeast, or southwest, but is not limited to these. As a result, when a judgment condition is issued that the room temperature of a room 18 having an opening 16 facing south, southeast, or southwest in summer deviates from the set temperature outside the allowable range, the room temperature of the room 18 is easily kept within the allowable range from the set temperature by accepting the proposal information and reducing the area of ​​the opening 16.

[0052] Furthermore, in this embodiment, since an outside air intake path 20 is formed that leads to the heat source unit 21 via the intake 191 and the underfloor space 19, a heat storage effect of the ground can be obtained. To explain further, in summer, when high-temperature outside air is taken in through the intake 191 and passes through the underfloor space 19, the taken-in air is cooled by the ground, which has a lower temperature than the temperature of the outside air. In winter, when low-temperature outside air is taken in through the intake 191 and passes through the underfloor space 19, the taken-in air is heated by the ground, which has a higher temperature than the temperature of the outside air. This makes it possible to reduce the required capacity of the air conditioning equipment 2.

[0053] Moreover, in this embodiment, the judgment condition calculation unit 33 calculates the number of air outlets 26 required in the room 18 that requires air conditioning. Specifically, the judgment condition calculation unit 33 calculates the number of air outlets 26 according to, for example, the floor area of ​​the room 18. This makes it possible to mechanically calculate the number of air outlets 26 that has been appropriately determined by a designer based on experience.

[0054] (5) Description As is apparent from the above embodiment, the present disclosure includes the following aspects.

[0055] The first aspect is an air conditioning capacity judgment system 3 that includes a storage unit 31, an acquisition unit 32, a judgment condition calculation unit 33, a judgment unit 34, and an output unit 35, and performs a pass / fail judgment of whether the air conditioning capacity of a building 1 having an air conditioning facility 2 satisfies a standard or not. The storage unit 31 stores basic conditions including an analysis result obtained by an analysis in which at least time history data of heat load is obtained as an output for each area division of a building model. The acquisition unit 32 acquires input conditions including the floor area of ​​the building 1 to be judged, the opening area, the capacity of the air conditioning facility 2 of the building 1, and information on the area division in which the building 1 is built. The judgment condition calculation unit 33 calculates the judgment condition based on the basic conditions according to the acquired input conditions. The judgment unit 34 performs a pass / fail judgment of whether the judgment condition satisfies the judgment criterion or not. The output unit 35 outputs the pass / fail judgment result of the judgment unit 34.

[0056] In the first aspect, the analysis is not performed each time, and therefore the cost, effort, and time required for the analysis are not required. Furthermore, the judgment conditions are determined by modifying the basic conditions including the analysis results obtained by the analysis, and therefore the analysis results obtained by the analysis can be reflected, enabling accurate pass / fail judgment.

[0057] The second aspect is an air conditioning capacity determination system 3 based on the first aspect. In the second aspect, the basic conditions include information on peak values ​​of the time history temperature data obtained by the above-mentioned analysis of the building model.

[0058] In the second aspect, the load on the storage unit 31 can be reduced.

[0059] The third aspect is an air conditioning capacity judgment system 3 based on the first or second aspect. In the third aspect, the air conditioning equipment 2 has a heat source unit 21, a plurality of conveying paths 22, a plurality of opening degree adjustment units 23, an air conditioning control unit 24, and an air conditioning input unit 25. The heat source unit 21 is capable of generating hot air or cold air. The conveying path 22 conveys the hot air or cold air from the heat source unit 21. The opening degree adjustment unit 23 is provided on the conveying path 22 and adjusts the opening degree of the conveying path 22. The air conditioning control unit 24 controls the opening degree adjustment unit 23. The air conditioning input unit 25 inputs a command to the air conditioning control unit 24. The output unit 35 further outputs, for each of the plurality of opening degree adjustment units 23, input items to be input from the air conditioning input unit 25 in order to identify the opening degree adjustment unit 23.

[0060] In the third aspect, when an installer inputs information to be input through the air conditioning input unit 25 in order to identify each of a plurality of opening degree adjustment units 23, the occurrence of input errors can be reduced.

[0061] The fourth aspect is an air conditioning capacity determination system 3 based on the first to third aspects. In the fourth aspect, the input conditions include information on the direction of the opening 16 of the building 1 to be determined. If the pass / fail determination result is no, the output unit 35 further outputs proposal information for reducing the area of ​​the opening 16 in a predetermined direction.
