Description

[Technical field]

[0001] The present invention relates to an air conditioner performance measuring method, an air conditioner performance measuring device, and a condition generator control method. [Background technology]

[0002] A simple method for measuring the performance of an air conditioner is known in which the compressor speed is fixed and the capacity of the air conditioner is not controlled, and the air conditioner is operated in a stable state to measure the performance. However, in such a constant operating state, i.e., a static operating state, the performance measurement is not performed under actual operating conditions, and there is a risk of a discrepancy between the measurement results and the performance in the actual usage environment.

[0003] Therefore, performance measurement while dynamically changing the operating state of the air conditioner is being considered. Performance measurement in such a dynamic operating state is sometimes called load-based performance measurement. According to the technology disclosed in Patent Document 1, a specific test environment such as a test room is prepared to measure the performance of the air conditioner in a dynamic operating state. According to this technology, electrical equipment and a human body model placed in the test room are controlled, and the performance of the air conditioner in a dynamic operating state is measured while taking into consideration the actual usage environment such as heat generation from the electrical equipment and the heat of daily life in the room.

[0004] [Patent Document 1] JP 2007-333557 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the technology disclosed in Patent Document 1, when performance measurements are carried out at different locations, it is necessary to create the same test room for each location in order to make the implementation environment the same. However, it is difficult to reproduce a completely identical test environment, including the external environment, etc., and there is a risk of variation in the results of the performance measurements.

[0006] Therefore, a method has been considered in which a condition generator consisting of an air conditioner different from the air conditioner being measured is provided in the test room. With this method, a virtual test room (virtual room) is emulated from the state of the air blown out from the air conditioner being measured, and the performance of the air conditioner being measured is measured while controlling the condition generator so that the air condition in the actual test room matches the air condition in the virtual room obtained by the emulation. With this method, it is possible to eliminate factors that depend on the environment, such as the thermal capacity of the test room, and therefore it is possible to measure the performance of the air conditioner under dynamic operating conditions while realizing a measurement environment with high reproducibility.

[0007] However, even with this emulation method, delays occur due to the control of the condition generator and the heat capacity of the air in the test room, and the change (response) in the actual test room state may be delayed compared to the state of the virtual room obtained by emulation. As a result, there is an issue that these delays may affect the results of performance measurements of air conditioners under dynamic operating conditions.

[0008] The present invention has been made in consideration of these problems, and has an object to provide an air conditioner performance measuring method, an air conditioner performance measuring device, and a condition generator control method that improve the accuracy of air conditioner performance measurement under dynamic operating conditions. [Means for solving the problem]

[0009] The air conditioner performance measuring method of the present invention measures the performance of an air conditioner that is dynamically operated in a test room equipped with a condition generator that generates measurement conditions. This air conditioner performance measuring method uses the air condition of the air blown out from the air conditioner to emulate the air condition of a virtual room that virtually reproduces an actual room, thereby obtaining future changes in the air condition of the virtual room, compensating for a delay in the air condition of the test room relative to the setting of the condition generator when the future changes in the air condition of the virtual room are used to set the condition generator, controlling the condition generator using the future changes in the air condition of the virtual room with the delay compensated as the setting, and measuring the performance of the air conditioner in the test room where the measurement conditions generated by the condition generator are satisfied.

[0010] The air conditioner performance measuring device of the present invention measures the performance of an air conditioner that is dynamically operated in a test room equipped with a condition generator that generates measurement conditions. This air conditioner performance measuring device has an emulation unit that uses the air condition of the air blown out from the air conditioner to emulate the air condition of a virtual room that virtually reproduces an actual room, thereby determining future changes in the air condition of the virtual room, a delay compensation unit that compensates for a delay in the air condition of the test room relative to the setting of the condition generator when the future changes in the air condition of the virtual room are used to set the condition generator, and controls the condition generator using the future changes in the air condition of the virtual room where the delay has been compensated for as the setting, and an air conditioning performance measuring unit that measures the performance of the air conditioner in a test room where the measurement conditions are generated by the condition generator.

[0011] The condition generator control method of the present invention controls a condition generator that is provided in a test room and generates conditions for performance measurement of a dynamically operated air conditioner. This condition generator control method uses the air condition of the air blown out from the air conditioner to emulate the air condition of a virtual room that virtually reproduces an actual room, thereby obtaining future changes in the air condition of the virtual room, compensates for a delay in the air condition of the test room relative to the setting of the condition generator when the future changes in the air condition of the virtual room are used to set the condition generator, and controls the condition generator using the future changes in the air condition of the virtual room, with the delay compensated, as a set value. Effect of the Invention

[0012] According to the air conditioner performance measuring method, air conditioner performance measuring device, and condition generator control method of the present invention, the delay in the change in the air condition of the test room relative to the set value input to the condition generator is compensated for with respect to the air condition of the virtual room obtained by emulation. By performing such delay compensation, when measuring the performance of a dynamically controlled air conditioner, the difference between the air condition of the test room and the air condition of the virtual room becomes smaller, thereby improving the accuracy of the performance measurement.

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the same components are designated by the same reference numerals, and duplicated description will be omitted.

[0015] (First embodiment) FIG. 1 is a schematic diagram of a test room 1. The illustrated test room 1 has a common configuration to each embodiment. According to this diagram, the test room 1 is provided with an air conditioner 2 to be measured, a measurement chamber 3 that collects air blown out from the air conditioner 2, and a condition generator 4 that takes in the air blown out from the measurement chamber 3 and generates conditions for performance measurement by making the air condition (temperature and humidity) in the test room 1 a predetermined air condition. As an example, the condition generator 4 is an air conditioner different from the air conditioner 2 and is capable of controlling temperature and humidity. The air conditioner 2 operates in conjunction with an outdoor unit 5, and the condition generator 4 operates in conjunction with an outdoor unit 6.

[0016] The air blown out from the air conditioner 2 is blown into the measurement chamber 3. Furthermore, part of the air blown out from the measurement chamber 3 is blown into the condition generator 4, and the rest is blown into the test room 1. In another embodiment, all of the air blown out from the measurement chamber 3 may be blown into the condition generator 4. The temperature and humidity of the air blown into the condition generator 4 are changed by the condition generator 4.

[0017] Two control units, an air conditioning performance measuring unit 7 that executes performance measurement of the air conditioner 2, and a virtual room calculation unit 8 that determines the target value of the condition generator 4, are integrated into the performance measuring device 9. The performance measuring device 9 is composed of a calculator (computer) equipped with a central processing unit (CPU), a memory unit, etc. The performance measuring device 9 executes specific programs stored in the memory unit to execute processes for realizing the functions of the air conditioning performance measuring unit 7 and the virtual room calculation unit 8. The air conditioning performance measuring unit 7 and the virtual room calculation unit 8 may be configured as a single computer or multiple computers.

[0018] The air conditioning performance measurement unit 7 is configured to calculate the air conditioning performance of the air conditioner 2 from the measured air condition in the test room 1 and the power consumption of the air conditioner 2. The air conditioning performance measurement unit 7 can perform dynamic performance measurement of the air conditioner 2 because the air conditioner 2 is dynamically controlled according to the measurement conditions.

[0019] The virtual room calculation unit 8 predicts the air conditions (temperature, humidity) of a virtual room (hereinafter referred to as a virtual room) through emulation using the measured air conditions of the air blown from the air conditioner 2, and controls the condition generator 4 so that the air conditions of the test room 1 match the air conditions of the virtual room. In this way, by using the condition generator 4 to match the air conditions of the test room 1 with the air conditions of the virtual room, it is possible to suppress variations in the measurement results of air conditioning performance caused by differences in the configurations of multiple test rooms 1 set up in different locations.

[0020] The entire test chamber 1 is covered with a heat insulating material 10. The test chamber 1 has a two-layer structure in which an inner ceiling 12 is provided inside an outer wall 11 of the ceiling, and is configured so that air blown from the condition generator 4 can be taken in between the outer wall 11 and the inner ceiling 12. A plurality of holes are provided in the inner ceiling 12, and the air blown from the condition generator 4 is diffused throughout the interior of the test chamber 1 through these holes. Note that, although the inner ceiling 12 is provided in the test chamber 1 in this embodiment, the inner ceiling 12 may not be provided, and the air blown from the condition generator 4 may be blown directly or indirectly into the test chamber 1.

[0021] The air conditioner 2 is connected to an outdoor unit 5 provided outside the test room 1 via piping or the like. The outdoor unit 5 is equipped with a compressor or the like, and the air conditioner 2 and the outdoor unit 5 operate together to blow out air of a specified temperature, humidity, and volume from the air conditioner 2.

[0022] In the vicinity of the intake port of the air conditioner 2, the indoor temperature T r The wet-bulb temperature measured by the wet-bulb thermometer 22 and the indoor temperature T measured by the thermometer 21 are measured. r Using the above, indoor humidity x r In addition, in the vicinity of the air outlet of the air conditioner 2, the blowing temperature T sA thermometer 23 for measuring the temperature and humidity, and a hygrometer 24 for directly measuring the humidity are provided. Since there is a temperature and humidity distribution at the air outlet of the air conditioner 2, instead of a wet-bulb thermometer that measures humidity by comparing it with the temperature measured by the thermometer, a hygrometer 24 is provided to directly measure the humidity x of the air blown out. s is preferably measured.

[0023] The air conditioner 2 is controlled together with the outdoor unit 5, and the power consumption P used for air conditioning the test room 1 is calculated using a power meter 25 provided in the air conditioner 2 and a power meter 53 provided in the outdoor unit 5. A thermometer 51 and a wet-bulb thermometer 52 are provided near the outdoor unit 5, and each measures the outdoor temperature T o and outdoor humidity x o Measure the outdoor temperature T o and outdoor humidity x o is not used in the first embodiment, but is used in the second embodiment. Note that a configuration in which a power meter is provided on only one of the air conditioner 2 and the outdoor unit 5 is also possible.

[0024] A thermometer 31 and a wet-bulb thermometer 32 are provided inside the measurement chamber 3. An airflow meter 33 is provided at the outlet of the measurement chamber 3. The airflow meter 33 calculates the differential pressure between two pressure gauges provided along the air flow, and calculates the blown air volume G from the air conditioner 2 based on the differential pressure. s Calculate.

[0025] Here, since there is a temperature and humidity distribution in the vicinity of the air outlet of the air conditioner 2, the temperature T s and humidity x s In contrast, the temperature T obtained by the thermometer 31 and the wet-bulb thermometer 32 may have an error. s ' and humidity x s ' is the outlet temperature T measured by the thermometer 23 and the hygrometer 24 installed near the outlet of the air conditioner 2. s and blowing humidity x sIn comparison, since the measurement chamber 3 is located at a distance from the air outlet of the air conditioner 2 and the measurement chamber 3 itself has a heat capacity, there may be an error from the actual state of the air blown out from the air conditioner 2. However, since the air blown out is in a stirred state inside the measurement chamber 3, it is possible to measure the state of the blown out air more stably.

[0026] Therefore, the temperature T obtained by the thermometer 31 and the wet-bulb thermometer 32 in the steady state in advance is s ' and humidity x s ', the temperature T blown from the air conditioner 2 measured by the thermometer 23 and the hygrometer 24 s and blowing humidity x s By calibrating the outlet temperature T s and blowing humidity x s In addition, when the measurement delay caused by the distance between the air outlet of the air conditioner 2 and the measurement chamber 3 is considered to be relatively small, the temperature meter 31 and the wet-bulb thermometer 32 are used to measure the air condition in the measurement chamber 3 without using the thermometer 23 and the hygrometer 24, and the measurement accuracy of the air outlet temperature T s and blowing humidity x s You may ask for.

[0027] The air conditioning performance measurement unit 7 measures the indoor temperature T r and indoor humidity x r , the blowing temperature T obtained using the thermometer 23, the hygrometer 24, and the air volume meter 33 s , outlet humidity x s (The temperature T obtained by the thermometer 31 and the wet-bulb thermometer 32 s ', humidity x s ') and the blown air volume G s , as well as the power consumption P measured by the power meters 25 and 53.

[0028] The air conditioning performance measurement unit 7 measures the indoor temperature T r and indoor humidity x r The enthalpy of the indoor air is calculated from the above, and the outlet temperature T s and outlet humidity x sThe air conditioning performance measurement unit 7 calculates the enthalpy of the air blown out from the air conditioner 2 using the enthalpy and the difference between the two. Then, the air conditioning performance measurement unit 7 calculates the blown out air volume G s The air conditioning capacity (refrigeration capacity / heating capacity) is obtained by multiplying the power consumption P by the power consumption P. Finally, the air conditioning performance measurement unit 7 calculates the air conditioning performance of the air conditioner 2 and the outdoor unit 5.

[0029] The virtual room calculation unit 8 calculates the blowing temperature T s , outlet humidity x s , and blowing air volume G s When the inputs of the above are received, the virtual room calculation unit 8 emulates the air condition of the virtual room using these inputs. Then, the virtual room calculation unit 8 sets a set value (set temperature T set , set humidity x set ) to the condition generator 4. In this way, the air conditioning performance of the air conditioner 2 can be measured in the test room 1 whose air conditions match those of the virtual room.

[0030] The condition generator 4 is composed of an air conditioner different from the air conditioner 2 to be measured, and operates together with the outdoor unit 6 connected via piping or the like. The condition generator 4 takes in a part or all of the air blown out from the measurement chamber 3, and calculates the set temperature T set , and set humidity x set It operates according to.

[0031] In addition, thermometers, hygrometers, and wet-bulb thermometers other than the thermometers 21, 23, and 51, the hygrometer 24, and the wet-bulb thermometers 22 and 52 may be provided inside and outside the test room 1. By using the measurement results of multiple thermometers, hygrometers, and wet-bulb thermometers, the indoor temperature T r and indoor humidity x r , outlet temperature T s and blowing humidity x s , and the outdoor temperature T o and outdoor humidity x o can be sought.

[0032] 2 is an explanatory diagram of the operation of the virtual room calculation unit 8 of this embodiment. In this diagram, the control flow is indicated by thin arrows, and the air flow is indicated by thick arrows (hatched with dots).

[0033] As indicated by the thick arrow, the air blown out from the air conditioner 2 passes through the measurement chamber 3, is changed to predetermined conditions (temperature, humidity) by the condition generator 4, and then is returned to the test room 1 and sucked back into the air conditioner 2.

[0034] On the other hand, as indicated by the thin arrow, the blowing temperature T s , outlet humidity x s and blowing air volume G s are input to a virtual room calculation unit 8. The virtual room calculation unit 8 has an emulation unit 81 and a delay compensation unit 82. Note that, in the present embodiment, an example has been described in which the emulation unit 81 and the delay compensation unit 82 are integrated to constitute the virtual room calculation unit 8, but the emulation unit 81 and the delay compensation unit 82 may be separate computers or software.

[0035] The emulation unit 81 measures the blown temperature T s , outlet humidity x s and blowing air volume G s The virtual room temperature T emu and virtual room humidity x emu In this emulation, the amount of heat entering and leaving the virtual room, specifically, the incoming sunlight, the state of ventilation with the outside (including drafts), and the heat generated by the people and electrical appliances living inside are reproduced.

[0036] More specifically, the emulation unit 81 calculates the state of the air blown from the air conditioner 2, that is, the blown temperature T s , outlet humidity x s and blowing air volume G sUsing various parameters such as the above, a differential equation is solved, taking into consideration the flow of heat in and out of the virtual room, to predict changes over time in the air condition (temperature, humidity) of the virtual room. These future predicted values ​​of the air condition of the virtual room are corrected by a delay compensation unit 82 at the subsequent stage and then used to control the condition generator 4. These future predicted values ​​of the air condition of the virtual room indicate the air condition that changes over time, and are expressed as the virtual room temperature T emu and virtual room humidity x emu As shown in the figure.

[0037] The delay compensation unit 82 calculates the virtual room temperature T emu and virtual room humidity x emu In addition, as in the emulation unit 81, the blowing temperature T s , outlet humidity x s and blowing air volume G s Accepted.

[0038] Here, the setting input to the condition generator 4 (set temperature T set , set humidity x set ) for the air condition in test room 1 (room temperature T r , indoor humidity x r ) change (response) will be delayed.

[0039] Therefore, the delay compensation unit 82 calculates the input blowing temperature T s , outlet humidity x s and blowing air volume G s The virtual room temperature T output from the emulation unit 81 is calculated by feedforward control using emu and virtual room humidity x emu The delay compensation unit 82 performs a correction to compensate for the delay in the set temperature T set and set humidity x set to the condition generator 4, which is controlled accordingly.

[0040] Furthermore, since the condition generator 4 controls the air condition in the test room 1 and there is uncertainty in the control, a control error may occur in the air condition. Therefore, the delay compensation unit 82 may be configured to compensate for such an error.

[0041] The condition generator 4 has a temperature adjustment unit 41 and a humidity adjustment unit 42, and the set temperature T set and set humidity x set By operating the condition generator 4 in this manner, the room temperature T r and indoor humidity x r , the virtual room temperature T emu and virtual room humidity x emu The temperature adjustment unit 41 and the humidity adjustment unit 42 are a control unit of the condition generator 4, and may be integrated into a condition generator control unit 43.

[0042] Fig. 3 is an explanatory diagram of the operation of the virtual room calculation unit 8 of the comparative example. In the configuration shown in this figure, the delay compensation unit 82 in the virtual room calculation unit 8 is omitted when compared with the virtual room calculation unit 8 of the first embodiment shown in Fig. 2.

[0043] Since the delay compensation unit 82 is omitted, the virtual room state (virtual room temperature T emu , virtual room humidity x emu ) is used as a set value to control the condition generator 4. In this type of control, delays occur due to the mechanical control of the condition generator 4 and the heat capacity of the air in the test room 1, so the state in the test room 1 (room temperature T r , indoor humidity x r ) will be delayed relative to the set value.

[0044] In this embodiment, a delay compensation unit 82 is provided after the emulation unit 81 as shown in FIG. 2, so that the delay-compensated set temperature T set and set humidity x set is used to control the condition generator 4. As a result, the air condition of the test room 1 (room temperature Tr , indoor humidity x r ) is calculated by the emulation unit 81 based on the virtual room air condition (virtual room temperature T emu , virtual room humidity x emu ) can be approximated.

[0045] The delay compensation unit 82 is configured, for example, in the following manner. First, a delay model is generated that indicates the delay of the air state in the test room 1 relative to the set value of the condition generator 4, and then a compensation model that compensates for that delay is generated. The delay compensation unit 82 is then configured using the compensation model generated in this manner.

[0046] In detail, first, a delay model is generated that models the delay that occurs when the delay compensation unit 82 is not present as in the comparative example of FIG. set , set humidity x set ) historical data, virtual room air condition (virtual room temperature T emu , virtual room humidity x emu ) historical data, air condition of test room 1 (room temperature T r , indoor humidity x r ) and the air condition of the air blown from the air conditioner 2 (blowout temperature T s , outlet humidity x s , air volume G s The delay model is constructed by machine learning using past data such as

[0047] Next, using the generated delay model, a compensation model is generated that compensates for the delay. For example, when one of the inputs to the delay model is changed, the output value changes in response to the change in the input. One of the output values ​​that changes is the air condition of test room 1. Then, a change in the input is determined that minimizes the deviation over time of the air condition of test room 1 after the change from the air condition of the virtual room. For example, a genetic algorithm can be used to repeat such input changes to determine the optimal change. Finally, a compensation model can be generated that compensates for the determined change.

[0048] In this way, a delay model is generated, and then a compensation model is generated, and the generated delay model can be used to configure the delay compensation unit 82. Note that in the above description, machine learning is used to generate the delay model and the compensation model, but the present invention is not limited to machine learning, and a mathematical model describing the phenomenon in the condition generator 4 may also be used.

[0049] Two specific examples of simulations for constructing a delay compensation unit 82 using machine learning are described below. In the first example, machine learning is performed using past measurement data, and the performance of the compensation model is verified by simulation, as shown in Figs. 4 and 5. In the second example, machine learning is performed using an explicit error of the indoor conditions of the test room 1 from the air conditions of the virtual room as a parameter, and the performance of the compensation model is verified by actual measurement, as shown in Figs. 6 and 7. In both examples, the simulation is performed only for temperature, and not for humidity.

[0050] In the first example, the virtual room temperature T emu Indoor temperature T r Then, a delay model was generated that shows the delay of the set temperature T set Change the set temperature T set The indoor temperature T obtained according to r ' and the virtual room temperature T emu Difference with (T r '-T set The set temperature T ') is minimized (smaller than or equal to a specified value). set ' is calculated. As a result, the virtual room temperature T emu The input is the set temperature T set A delay model is generated with output '.

[0051] FIG. 4 is a graph showing the validity of the delay model obtained by the machine learning of the first example. In this graph, the vertical axis shows temperature normalized to a number between −1 and +1, and the horizontal axis shows time in seconds. The dashed line shows the virtual room temperature T obtained by the emulation unit 81.emu The solid line indicates the room temperature T r The thin dotted line shows the virtual room temperature T emu The indoor temperature T obtained by compensating for the delay r In this figure, the area surrounded by a two-dot chain line rectangle in the upper part is shown enlarged in the lower part.

[0052] As shown in the figure, the indoor temperature T r ' is the measured indoor temperature T r In this way, since the two match most of the time, or the difference is equal to or less than a predetermined value, it can be understood that the delay model is correctly constructed.

[0053] Figure 5 is a graph showing the performance of a compensation model generated through machine learning. In this figure, the area enclosed in a two-dot dashed rectangle in the upper part is shown enlarged in the lower part.

[0054] In this figure, as in Figure 4, the virtual room temperature T emu For comparison with Fig. 4, the indoor temperature T r Furthermore, the thin solid line indicates the virtual room temperature T emu The setting for the condition generator 4, in which the delay is compensated for using the compensation model for the setting temperature T set The thin dotted line indicates the set temperature T set The temperature of test room 1 (indoor temperature T r The dashed line (virtual room temperature T emu ) and thin dotted line (indoor temperature T r There are many overlapping parts with the dashed line, and the small "dots" that make up the thin dotted line are shown in white where they overlap with the dashed line.

[0055] As shown in this figure, the virtual room temperature T emu Using the compensation model, the set temperature Tset ' is generated. And this set temperature T set When ' is used to control the condition generator 4, the simulation result can be obtained by using a delay model, and the indoor temperature T r ' is required.

[0056] Virtual room temperature T emu (shown by the dashed line) is the indoor temperature T obtained using the delay model. r Since the delay compensation unit 82 is configured using this compensation model, the virtual room temperature T emu Indoor temperature T r Since the delay in the measurement is suppressed, the accuracy of the performance measurement of the air conditioner 2 using the virtual room can be improved.

[0057] In the second example, the delay model is further generated by machine learning that explicitly uses the error of the indoor conditions of the test room 1 from the air conditions of the virtual room as a parameter. That is, in the compensation model generated based on this delay model, not only the delay but also the error can be directly compensated.

[0058] FIG. 6 is a graph showing the performance of the compensation model generated through machine learning in the second example. In this figure, the temperature on the vertical axis is shown without being normalized, as compared to the examples in FIGS. 4 and 5. The circles indicate the setting value (setting temperature T set ) The solid line indicates this set value (set temperature T set ) based on the indoor temperature T obtained using a delay model r The dashed line indicates the virtual room temperature T emu Shows.

[0059] As shown in the figure, the indoor temperature T r and the virtual room temperature T shown by the dashed line emuIn this way, since the two match most of the time or the difference is equal to or less than a predetermined value, it can be understood that the delay model is correctly constructed.

[0060] FIG. 7 is a graph showing the measured temperature of the test room 1 when the delay compensation unit 82 generated using the compensation model generated through machine learning is actually used. The circles indicate the set value (set temperature T set ) The dashed line indicates the virtual room temperature T emu The triangle indicates this setting (set temperature T set ) The indoor temperature T measured in the test room 1 controlled based on r Shows.

[0061] In this second example, the measured indoor temperature T r and the virtual room temperature T shown by the dashed line emu In this way, since the two match most of the time, or the difference is equal to or less than a predetermined value, it can be understood that the delay has been compensated for by the delay compensation unit 82.

[0062] According to the performance measurement method of the air conditioner 2 of the first embodiment, the air condition of the virtual room obtained by the emulation unit 81 (virtual room temperature T emu , virtual room humidity x emu ), the delay compensation unit 82 sets the set value (virtual room temperature T emu , virtual room humidity x emu ) for the air condition of test room 1 (room temperature T r , indoor humidity x r By performing this delay compensation, the air condition (room temperature T r , indoor humidity x r ) and the virtual room air condition (virtual room temperature T emu , virtual room humidity x emu ) becomes smaller, the accuracy of the performance measurement of the air conditioner 2 can be improved.

[0063] According to the performance measurement method of the air conditioner 2 of the first embodiment, the delay compensation unit 82 measures the air condition of the air blown out from the air conditioner 2 (blowout temperature T s , outlet humidity x s , air volume G s ) is used for feedforward control. By performing such feedforward control, it is possible to improve the accuracy of the performance measurement of the air conditioner 2.

[0064] According to the performance measurement method of the air conditioner 2 of the first embodiment, the air condition of the virtual room reproduced by the condition generator 4 is the virtual room temperature T emu and virtual room humidity x emu In this way, by reproducing both the temperature and humidity of the virtual room in the test room 1, the reproducibility of the measurement conditions of the air conditioner 2 is increased, and the accuracy of the performance measurement of the air conditioner 2 can be improved.

[0065] According to the performance measurement method of the air conditioner 2 of the first embodiment, the virtual room state (virtual room temperature T emu , virtual room humidity x emu ) for the air condition of test room 1 (room temperature T r , indoor humidity x r A delay model is then generated that indicates the delay in the change (response) of the virtual room temperature T emu ', Virtual room humidity x emu ') is obtained, and a compensation model used to compensate for the delay is generated based on the change. In this way, after the delay model is generated, the compensation model is generated using the generated delay model, thereby simplifying the method of configuring the model.

[0066] According to the first embodiment of the method for measuring the performance of the air conditioner 2, in compensating for the delay, the error of the air condition in the test room 1 relative to the air condition in the virtual room when the delay has been compensated for is further compensated for. In this way, by compensating for not only the delay but also the error, it is possible to improve the accuracy of the performance measurement of the air conditioner 2.

[0067] Second embodiment In the first embodiment, the delay compensation unit 82 shown in FIG. 2 uses a delay model to calculate the air condition (blowout temperature T s , outlet humidity x s , air volume G s ), the virtual room air condition (virtual room temperature T emu , virtual room humidity x emu ) was subjected to delay compensation. In the second embodiment, an example in which further other parameters are used to improve the accuracy of delay compensation will be described.

[0068] 8 is an explanatory diagram of the operation of the virtual room calculation unit 8 of the second embodiment. According to this diagram, the delay compensation unit 82 of the virtual room calculation unit 8 receives the air condition of the air blown from the air conditioner 2 (blowout temperature T s , outlet humidity x s , air volume G s ), the air condition in the test room 1 (room temperature T r , indoor humidity x r ) and the air condition outside the test room 1 (outdoor temperature T o , outdoor humidity x o ) are input. Based on these inputs, the delay compensation unit 82 calculates the virtual room state (virtual room temperature T emu , virtual room humidity x emu ) is subjected to delay compensation, and the compensated value is applied to the setting value of the condition generator 4 (setting temperature T set , set humidity x set ) is used.

[0069] The delay in the response of the air condition in the test room 1 to the set value input to the condition generator 4 is due to delays caused by the control of the condition generator 4 and the heat capacity of the air in the test room 1, as well as heat conduction / heat radiation from the outside of the test room 1 through the insulation material 10. In particular, since the outdoor unit 5 becomes hot, the outdoor temperature T o and outdoor humidity x oThe feedforward using compensates for the delay due to heat conduction / heat radiation from outside the test chamber 1.

[0070] Furthermore, the delay compensation unit 82 determines the air condition in the test room 1 (room temperature T r , indoor humidity x r ) to set the condition generator 4 setting value (set temperature T set , set humidity x set ) for the air condition in test room 1 (room temperature T r , indoor humidity x r ) response delay / advance can be directly known.

[0071] Therefore, the air condition in the test room 1 (room temperature T r , indoor humidity x r ) is the set value of condition generator 4 (set temperature T set , set humidity x set ), the compensation amount is further increased, and the air condition in the test room 1 (room temperature T r , indoor humidity x r ) is the set value of condition generator 4 (set temperature T set , set humidity x set ), the amount of compensation is reduced. r , indoor humidity x r ) feedback control can optimally compensate for the delay.

[0072] In this embodiment, the delay compensation unit 82 determines the air condition (blowout temperature T s , outlet humidity x s , air volume G s ), the air condition in the test room 1 (room temperature T r , indoor humidity x r ), and the air condition outside the test room 1 (outdoor temperature T o , outdoor humidity x o Even in such cases, a delay model and a compensation model can be generated by machine learning by increasing the number of parameters handled during model generation.

[0073] According to the performance measurement method of the air conditioner 2 of the second embodiment, the delay compensation unit 82 further determines the air condition inside the test room 1 (the indoor temperature T r , indoor humidity x r ) is used to compensate for the delay. By performing such feedback control, it becomes possible to appropriately adjust the amount of compensation for the delay, and therefore it is possible to further improve the accuracy of the performance measurement of the air conditioner 2.

[0074] According to the performance measurement method of the air conditioner 2 of the second embodiment, the delay compensation unit 82 further determines the air condition outside the test room 1 (outdoor temperature T o and outdoor humidity x o In this way, the delay is compensated for by feedforward control using the state of the air blown from the air conditioner 2 (blowout temperature T s , outlet humidity x s , air volume G s ) is used to perform feedforward control, making it possible to appropriately adjust the amount of delay compensation, thereby enabling further improvement in the accuracy of performance measurement of the air conditioner 2.
