[First Embodiment]
Hereinafter, an evaluation support apparatus, method, and program for an air conditioning system according to a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram for explaining an evaluation support apparatus (hereinafter referred to as “evaluation support apparatus”) of an air conditioning system according to the present embodiment. The evaluation support apparatus 10a includes one outdoor unit 2 and a plurality of indoor units 5 connected to the outdoor unit 2 (hereinafter, an indoor unit connected to the outdoor unit 2 is referred to as a “connected indoor unit 5”. SEER and SCOP, which are evaluation values related to energy saving, of the air conditioning system 1 including the indoor unit) are calculated.
In the following description, for the sake of convenience, the evaluation support device 10a and the outdoor unit 2 of the air conditioning system 1 to be evaluated will be described on a one-to-one basis. However, for various outdoor units, By providing each of the following functions, versatility can be provided.

  FIG. 2 is a block diagram illustrating an example of a hardware configuration of the evaluation support apparatus 10a according to the present embodiment. As shown in FIG. 2, the evaluation support apparatus 10 a includes, for example, a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12 for storing a program executed by the CPU 11, and a work when each program is executed. A RAM (Random Access Memory) 13 that functions as an area, a hard disk drive (HDD) 14 as a mass storage device, a communication interface 15 for connecting to a network, and an access unit 17 in which an external storage device 16 is mounted And an input unit 18 such as a keyboard and a mouse, and an output unit 19 such as a liquid crystal display device for providing information to the user. These units are connected via a bus 20.

Various programs (for example, evaluation support programs) are stored in the ROM 12, and the CPU 11 reads out the programs from the ROM 12 to the RAM 13 and executes them to implement various processes.
Note that the storage medium for storing the program executed by the CPU 11 is not limited to the ROM 12. For example, other auxiliary storage devices such as a magnetic disk, a magneto-optical disk, and a semiconductor memory may be used.

The evaluation support apparatus 10a may exist, for example, as a system independent of the air conditioning system, or is provided in the apparatus as a part of a function of an apparatus related to the air conditioning system (for example, a central controller). It may be done.
The evaluation support apparatus 10 may be installed at the manufacturer of the air conditioning system and operated by a worker at the manufacturer, or may be installed at the owner side of the air conditioning system and may be installed by an operator on the owner side. It may be operated. Further, by connecting the terminal on the owner side and the evaluation support apparatus 10 installed at the manufacturer via a network, the SEER and SCOP in the evaluation support apparatus 10 are determined based on the input information input from the terminal on the owner side. It is good also as an aspect which is calculated and a calculation result is displayed on the terminal of an owner side. Thus, the usage mode of the air conditioning system is not particularly limited.

  FIG. 3 is a functional block diagram showing the functions provided in the evaluation support apparatus 10a in an expanded manner. As shown in FIG. 3, the evaluation support apparatus 10 a includes an input unit 21, a storage unit 22, an integration unit 23, a system performance coefficient acquisition unit (hereinafter referred to as “system COP acquisition unit”) 24, a period energy efficiency acquisition unit ( Hereinafter, a “SEER acquisition unit”) 25, a period performance coefficient acquisition unit (hereinafter referred to as “SCOP acquisition unit”) 26, and an output unit 27 are provided.

The input unit 21 is for inputting identification information for specifying the connected indoor unit 5 connected to the outdoor unit 2 of the air conditioning system 1 to be evaluated. The identification information includes at least the indoor unit type (wall mounted, ceiling cassette, with duct, etc.) and the indoor unit capacity.
As an input mode of the indoor unit identification information, a pull-down method is used on the display screen so that all indoor unit types and indoor capacities that can be connected to the outdoor unit of the air conditioning system are selectably displayed. One example is to select the appropriate type and indoor unit capacity from among them and perform the confirmation operation. The input mode of the identification information is not particularly limited as long as the type and capacity of the connected indoor unit 5 can be input.

The storage unit 22 includes first information in which identification information of each indoor unit connectable to the outdoor unit 2 and characteristic values related to the heat exchanger of the indoor unit are associated, an integrated characteristic value, and a system performance coefficient (system COP). Are stored, second information associated with the system COP and SEER, fourth information associated with the system COP and SCOP, and the like.
These pieces of information stored in the storage unit 22 may be acquired by downloading from a predetermined server via a communication medium (for example, the Internet).
The first information to the fourth information will be sequentially described.

First, the first information will be described in detail.
The characteristic value C related to the heat exchanger of each indoor unit in the first information is the effectiveness of the heat exchanger. For example, as shown in the following equation (1), the heat capacity flow rate Cmin and the heat exchange effective rate ε are mainly used. It is calculated by an arithmetic expression using various parameters. As shown in the equation (2), the heat exchange effective rate ε is calculated by an arithmetic expression having the refrigerant circulation amount F as a main parameter.

C = f (Cmin, ε) (1)
ε = f (F) (2)

Here, the refrigerant circulation amount F changes according to the indoor unit capacity. For example, in the case of an indoor unit with a capacity of 28 [kW], assuming that the indoor unit maximum capacity at the rated load of the outdoor unit is 112 [kW], the refrigerant circulation amount F ₍₂₈₎ is calculated using the following equation (3). Is done.

F ₍₂₈₎ = F _tol × (28/112) (3)

In formula (3), F _tol is the total circulation amount at the rated load, and is a value unique to the outdoor unit. The indoor unit maximum capacity 112 [kW] is also a value unique to the outdoor unit. In the above equation (3), if the compressor frequency [Hz] at the rated load is used instead of the total circulation amount F _tol at the rated load, the compressor frequency corresponding to the indoor unit capacity can be obtained. .

  In this way, for each indoor unit that can be connected to the outdoor unit 2, the characteristic value C is calculated in consideration of the refrigerant circulation amount corresponding to the indoor unit capacity, and the calculated characteristic value C is used as identification information (indoor The first information is created by associating with the combination of the machine type and the capacity.

  The integrating unit 23 acquires the characteristic value C associated with the identification information of the connected indoor unit 5 input from the input unit 21 from the first information, and integrates the acquired characteristic value C to thereby calculate the integrated characteristic value. ΣC is calculated.

  For example, when two wall-mounted indoor units with a capacity of 28 [kW] and two indoor units with a ceiling cassette capacity of 56 [kW] are connected, the integrated characteristic value ΣC is as follows.

ΣC = 2 × C ₍₂₈₎ + 2 × C ₍₅₆₎ (4)

In the above formula (4), C ₍₂₈₎ is the effectiveness of the heat exchanger of the wall-mounted type capacity unit 28 [kW], and C ₍₅₆₎ is the heat exchange of the ceiling cassette type capacity unit 56 [kW]. The effectiveness of the vessel.

Next, the second information will be described.
For example, there are a plurality of combination patterns of indoor units connected to the outdoor unit 2. For example, a pattern in which two wall-mounted indoor units with a capacity of 56 [kW] are connected, a pattern in which two ceiling cassette-type indoor units with a capacity of 56 [kW] are connected, and a ceiling cassette type indoor unit with a capacity of 28 [kW] A pattern in which four units are connected, a pattern in which two wall-mounted indoor units with a capacity of 28 [kW] and two wall-mounted indoor units with a capacity of 56 [kW] are connected.

  Therefore, the system COP is calculated in advance for each connection pattern of the indoor units, and the second information is created by associating the system COP with the integrated characteristic value ΣC. Here, the second information may be provided corresponding to each connection pattern of the indoor units. When the system COP characteristics are similar between the connection patterns, an approximate curve of these characteristics is obtained. Thus, the system COP characteristics for each connection pattern may be integrated into one. Further, since the value of the system COP changes between cooling and heating, the second information may be prepared for both cooling and heating. In FIG. 4, an example of the 2nd information at the time of heating at the time of using an approximated curve is shown.

  The system COP acquisition unit 24 acquires a system COP corresponding to the integration characteristic value ΣC calculated by the integration unit 23 from the second information stored in the storage unit 22. At this time, when the second information corresponding to the cooling and the second information corresponding to the heating are stored in the storage unit 22, the system COP may be acquired from the respective second information of the heating and the cooling. .

Next, the third information and the fourth information will be described.
By performing tests and simulations in advance for each connection pattern of the indoor units that can be connected to the outdoor unit 2, the relationship between the system COP and SEER is obtained, and these approximate curves are obtained to obtain third information. FIG. 5 shows an example of the third information. In FIG. 5, the horizontal axis is the system COP, and the vertical axis is the SEER.
Similarly, the relationship between the system COP and SCOP is obtained for each connection pattern, and the fourth information is obtained by obtaining these approximate curves. FIG. 6 shows an example of the fourth information. In FIG. 6, the horizontal axis represents the system COP and the vertical axis represents the SCOP.

  Here, the system COP associated with SEER and SCOP may be one during cooling or one during heating. For example, the third information and the fourth information need only be prepared in accordance with the system COP obtained in the system COP acquisition unit described above. Further, when both the system COP during cooling and the system COP during heating are obtained by the system COP acquisition unit 24, for example, for SEER, third information associated with the system COP during cooling is prepared. And about SCOP, it is good also as preparing the 4th information linked | related with the system COP at the time of heating.

The SEER acquisition unit 25 acquires SEER corresponding to the system COP acquired by the system COP acquisition unit 24 from the third information.
The SCOP acquisition unit 26 acquires the SCOP corresponding to the system COP acquired by the system COP acquisition unit 24 from the fourth information.
The output unit 27 is a display device, for example, and presents the EESR acquired by the SEER acquisition unit 25 and the SCOP acquired by the SCOP acquisition unit 26 to the user by displaying them on the display screen.

Next, a processing procedure in the evaluation support apparatus 10a having the above configuration will be described with reference to FIG.
First, when the user operates the input unit 21, the indoor unit type and the indoor unit capacity are sequentially input as identification information of the connected indoor unit 5 connected to the outdoor unit 2. When the identification information of the connected indoor unit 5 input by the input unit 21 is acquired (step SA1), the characteristic value C of each connected indoor unit 5 is acquired from the first information (step SA2), and the acquired characteristic value C is integrated. Thus, the integrated characteristic value ΣC is calculated (step SA3). Next, the system COP corresponding to the integrated characteristic value ΣC is acquired from the second information (step SA4). Subsequently, the SEER corresponding to the system COP is acquired from the third information (step SA5), and the SCOP corresponding to the system COP is acquired from the fourth information (step SA6). The EESR and SCOP acquired in this way are displayed on the output unit 27 and presented to the user (step SA7).

As described above, according to the evaluation support apparatus, method, and program for the air conditioning system according to the present embodiment, the identification information for identifying the connected indoor unit 5 connected to the outdoor unit 2 is input by a simple operation. , SEER and SCOP can be obtained. Thereby, it becomes possible to reduce a user's labor and time.
Here, in the present embodiment, the effectiveness of the heat exchanger is used as the characteristic value C. However, instead of this, the heat exchange capability may be used. The heat exchange capacity is expressed by the following equation (5).

  Heat exchange capacity = heat exchanger effectiveness x (heat exchanger temperature-intake air temperature) (5)

[Second Embodiment]
The characteristic value C set in the first information according to the first embodiment described above, that is, the effectiveness of the heat exchanger is the indoor unit capacity with respect to the indoor unit maximum capacity at the rated load (load 100%) of the outdoor unit 2. Based on this ratio, the refrigerant circulation amount F was calculated, and the refrigerant circulation amount F was calculated in consideration.
However, the outdoor unit 2 has an indoor unit capacity exceeding the rated load (for example, an indoor unit capacity exceeding 112 [kW] in the above case) or an indoor unit capacity not satisfying the rating (for example, less than 112 [kW] in the above case). Indoor unit capacity) may be connected.

  Thus, the sum of the indoor unit capacities connected to the outdoor unit 2 is a capacity other than the maximum indoor unit capacity corresponding to the rating of the outdoor unit 2 (for example, 112 [kW] in the example of the first embodiment). In such a case, the integrated characteristic value ΣC obtained from the first information described above includes an error due to a change in capacity.

  Therefore, in the present embodiment, in order to reduce the error of the integrated characteristic value due to the difference in the total indoor unit capacity of such connected indoor units, the evaluation support apparatus according to the first embodiment shown in FIG. As shown in FIG. 8, fifth information (not shown) in which the first correction value, which is the correction value of the integrated characteristic value ΣC, and the total capacity of the connected indoor unit 5 are associated with each other, and the integrated characteristic obtained by the integrating unit 23. A first correction unit 28 that corrects the value ΣC is further provided. FIG. 8 is a functional block diagram showing the functions provided in the evaluation support apparatus 10b according to this embodiment in an expanded manner. Hereinafter, the 5th information and the 1st correction part 28 which are the characteristic parts of the evaluation assistance apparatus 10b which concern on this embodiment are mainly demonstrated. The fifth information is stored in the storage unit 22 and referenced by the first correction unit 28.

First, the fifth information will be described.
In each connection pattern of the indoor units connected to the outdoor unit 2, it depends on the integrated characteristic value (integrated value of the effectiveness of the heat exchanger) in consideration of the refrigerant circulation amount corresponding to the indoor unit capacity, and the indoor unit capacity Without a constant refrigerant circulation amount (for example, the refrigerant circulation amount when the outdoor unit 2 exhibits its rated capacity, in other words, the compressor frequency at the rated load) (heat exchanger) Are calculated, and the relationship between the total heat capacity of the indoor units connected to the outdoor unit 2 and the integrated characteristic value is obtained.

  FIG. 9 shows the relationship between the total capacity of the connected indoor units 5 and the integrated characteristic value ΣC. In FIG. 9, the horizontal axis indicates the ratio based on the indoor unit maximum capacity 112 [kW] when the total capacity of the connected indoor units is 100% [%] of the outdoor functional force. That is, when the total capacity of the indoor units connected to the outdoor unit 2 is 112 [kW], it is 100 [%]. The vertical axis represents the integrated characteristic value ΣC. In FIG. 9, the solid line is an approximate curve (hereinafter referred to as “hereinafter“ The broken line is an approximate curve (hereinafter referred to as “approximate curve A”) obtained by approximating the characteristics in each connection pattern when the refrigerant circulation amount is constant (in other words, when the compressor frequency is constant). Curve B ”).

  As can be seen from FIG. 9, in the range where the total capacity of the connected indoor units 5 exceeds 100 [%], it can be seen that the characteristics of the two differ as the total capacity increases. The first correction value for the total capacity of the connected indoor units is obtained from FIG. Specifically, the characteristic of the first correction value is obtained by dividing the approximate curve B by the approximate curve A. FIG. 10 shows an example of fifth information in which the total capacity of the connected indoor units is associated with the first correction value. In FIG. 10, the horizontal axis represents the indoor unit total capacity, and the vertical axis represents the first correction value.

The first correction unit 28 acquires a first correction value corresponding to the total capacity of the connected indoor units 5 connected to the outdoor unit 2 from the fifth information, and calculates the integrated characteristic value ΣC calculated by the integrating unit 23. Correction is performed using one correction value. Specifically, the integrated characteristic value ΣC may be multiplied by the first correction value.
In the subsequent processing, the system COP is acquired using the corrected integrated characteristic value ΣC.

  According to the present embodiment, it is possible to reduce an error in the integrated characteristic value ΣC due to a difference in the total capacity of the connection indoor units 5 connected to the outdoor unit 2. Thereby, it is possible to improve the calculation accuracy of the integrated characteristic value ΣC. Further, the heat exchange capability can be used as the characteristic value as in the first embodiment described above.

[Third Embodiment]
The second information according to the first embodiment described above relates to the system COP corresponding to the integrated characteristic value ΣC. In the present embodiment, by using the sixth information and the seventh information instead of the second information, a system COP corresponding to the integrated characteristic value ΣC (that is, the integrated value of the effectiveness of the heat exchanger) is obtained. Different from the first embodiment described above.

Hereinafter, differences from the first embodiment will be mainly described.
For each connection pattern of the indoor units connected to the outdoor unit 2, the relationship between the indoor heat exchange amount (indoor functional force) [W] and the integrated characteristic value ΣC, the sum of the inverter power consumption and the compressor power consumption (hereinafter referred to as “ When the relationship between [W] and the integrated characteristic value ΣC is examined, FIGS. 11 and 12 are obtained.
FIG. 11 shows an approximate curve of the characteristics of each connection pattern in the relationship between the integrated characteristic value ΣC and the indoor heat exchange amount, and FIG. 12 shows the connection pattern in the relationship between the integrated characteristic value ΣC and the device power consumption. It is the figure which showed the approximate curve of the characteristic.
As shown in FIGS. 11 and 12, it was confirmed that the indoor heat exchange amount and the device power consumption have a correlation with the integrated characteristic value ΣC.

  Therefore, for the calculation of the system COP according to the present embodiment, the integration characteristic value ΣC is used by using the parameter correlated with the integration characteristic value ΣC, that is, the indoor heat exchange amount characteristic shown in FIG. 11 and the equipment power consumption characteristic shown in FIG. The indoor heat exchange amount and device power consumption corresponding to the value ΣC are acquired, and the system COP is calculated by adding the input of the indoor and outdoor fan motors to the acquired values.

Specifically, the indoor heat exchange amount characteristic shown in FIG. 11 is stored in the storage unit 23 as sixth information, and the apparatus power consumption characteristic shown in FIG. 12 is stored as seventh information.
The system COP acquisition unit 24 acquires the indoor heat exchange amount corresponding to the integrated characteristic value ΣC from the sixth information, and acquires the device power consumption corresponding to the integrated characteristic value ΣC from the seventh information. Then, by calculating the obtained information, the indoor fan motor input and the power consumption of the indoor / outdoor fan motor that are held in advance using the following arithmetic expressions, the system COP during heating and the cooling power during cooling are calculated. Obtain at least one of the system COPs.
The system COP at the time of heating is calculated | required by the following (6) Formula.

System COP (heating)
= (Indoor heat exchange amount + Indoor fan input) / (Equipment power consumption + Indoor and outdoor fan power consumption) (6)

[Fourth Embodiment]
In the evaluation support apparatus 10a in the first embodiment described above, standby power is not considered in obtaining SEER and SCOP. However, it has been found that the sensitivity of SEER to standby power is greater than expected, and that SEER evaluation accuracy can be improved by correcting SEER according to standby power.
In the present embodiment, as shown in FIG. 13, the eighth information (not shown) and the second correction unit are configured as a configuration for correcting the SEER obtained by the SEER acquisition unit 25 with the second correction value corresponding to the standby power. 29 is provided to improve SEER evaluation accuracy. Here, the eighth information is information stored in the storage unit 22. FIG. 13 is a functional block diagram showing the functions provided in the evaluation support apparatus 10c according to this embodiment in an expanded manner.

  Specifically, by performing tests and simulations in advance, the relationship between SEER and standby power PTO is obtained for each connection pattern or each connected indoor unit, and these approximate characteristics are obtained. Then, by dividing this approximate characteristic by a reference characteristic (for example, the standby power PTO-SEER characteristic when the connection pattern has the largest SEER value), the standby power PTO and the second correction value are associated with each other. The obtained eighth information is obtained. FIG. 14 shows an example of the eighth information. The storage unit 22 also stores ninth information that associates the identification information of each indoor unit with the standby power. As the standby power, for example, one determined by regulation may be used, or standby power corresponding to an indoor fan input may be set for each indoor unit.

  The 2nd correction | amendment part 29 calculates the standby power of the whole system by each acquiring the standby power regarding the connection indoor unit 5 from 9th information, and integrating | accumulating the acquired standby power. Then, the second correction value corresponding to the integrated standby power is acquired from the eighth information, and the SEER is corrected using the acquired second correction value.

  Similarly, for the SCOP, information relating the SCOP and the standby power PTO may be stored in the storage unit 22 and correction may be performed using this information.

  As described above, according to the evaluation support apparatus 10c according to the present embodiment, the SEER and SCOP values obtained by the SEER acquisition unit 25 and the SCOP acquisition unit 26 are corrected by the second correction value corresponding to the standby power. Therefore, it is possible to improve the evaluation accuracy of SEER and SCOP.
