Summary of the Invention

Problems to be Solved by the Invention

[0004] When performing control as described above, the amount of energy consumption related to the air conditioner is reduced. However, depending on the temperature of the outside air, outside air introduction may impair the comfort of workers. In addition, the comfort of the people in the building is also related to the productivity of the people in the building. In other words, there is a problem that when the comfort of the people in the building is impaired, it is difficult to improve the productivity of the people in the building. The present invention has been made to solve the above problems, and an object thereof is to provide an air conditioner that can easily achieve both an improvement in productivity and an improvement in energy-saving effect.

Means for Solving the Problems

[0005] To achieve the above object, the present invention provides the following means. An air conditioning system according to one aspect of the present invention is an air conditioning system having an air conditioner capable of introducing outside air into a target space, characterized in that it is provided with: a setting unit for setting a target temperature which is a temperature related to productivity improvement; an index estimation unit for estimating an air conditioning index related to people staying in the target space; a calculation unit for calculating the amount of energy reduction consumed by the air conditioner when the outside air is introduced into the target space; and a control unit that performs additional control, which consumes an amount of energy within the reduction amount when the temperature of the target space exceeds the target temperature when the outside air is introduced, thereby bringing the air conditioning index closer to a predetermined value that improves productivity.

[0006] According to the first aspect of the present invention, the amount of energy consumed by the air conditioner can be easily reduced by introducing outside air. Introducing outside air may reduce the temperature of the target space (hereinafter also referred to as the room). On the other hand, introducing outside air alone may not reduce the room temperature to the target temperature. In that case, the air conditioner can be operated to lower the temperature of the target space by consuming less energy than the amount of energy consumed by the air conditioner that is reduced by introducing outside air.

[0007] Thus, the air conditioning system according to the first embodiment makes it easier to achieve both improved energy efficiency and improved comfort with respect to the air conditioner. Furthermore, the improved comfort makes it easier to increase the productivity of occupants.

[0008] In the first embodiment of the above invention, the additional control preferably includes at least one of the following: a control to increase the flow velocity of the conditioned airflow blown from the air conditioner into the target space, and a control to lower the set temperature of the air conditioner.

[0009] In this way, the control unit can easily achieve both improved productivity and improved energy efficiency by performing additional control processing, such as increasing the flow velocity of the air conditioning airflow and lowering the set temperature.

[0010] In the first embodiment of the above invention, an image estimation unit is further provided that estimates the number of occupants, which is the number of people staying in the target space, based on image information including the people staying in the target space, and it is preferable that the index estimation unit estimates the air conditioning index using the number of occupants.

[0011] In this way, by providing an image estimation unit, the number of people in the room can be estimated. Using the estimated number of people in the room, the indicator estimation unit can estimate the air conditioning index. Furthermore, by estimating the air conditioning index using the estimated number of people in the room, the indicator estimation unit can easily calculate an air conditioning index with high accuracy.

[0012] In the first embodiment of the above invention, it is preferable that the image estimation unit can estimate information about the clothing of the person staying there, and the index estimation unit uses the information about the clothing to estimate the air conditioning index.

[0013] In this way, the image estimation unit can estimate information about the clothing of the people staying there. Using the estimated clothing information, the indicator estimation unit can estimate the air conditioning index. Furthermore, by estimating the air conditioning index using the estimated clothing information, the indicator estimation unit can easily calculate an air conditioning index with high accuracy.

[0014] In the first embodiment of the above invention, it is preferable that the indicator estimation unit estimates a predicted first temperature used to determine the air conditioning index by inputting information about the work content, information about clothing, the temperature of the target space, the temperature and humidity of the outside air, the set temperature of the air conditioner, and the number of people in the room into a trained learning model that has been trained by machine learning to estimate the air conditioning index for the person staying in the target space.

[0015] In this way, the indicator estimation unit can use machine learning to estimate a predicted first temperature, which is the indoor temperature after a predetermined time has elapsed. The predicted first temperature is used to determine the air conditioning index. Furthermore, by estimating the air conditioning index using the predicted first temperature, the indicator estimation unit can easily calculate an air conditioning index with high accuracy. [Effects of the Invention]

[0016] According to the air conditioner of the present invention, control that can easily achieve both energy saving improvement and productivity improvement can be performed.

Embodiments for Carrying Out the Invention

[0018] 〔First Embodiment〕 Description of Configuration The air conditioner 10 according to the first embodiment of this invention will be described while referring to FIGS. 1 and 2. The air conditioner 10 of this embodiment is composed of at least one or more air conditioners 50, an outside air introduction part 51, and a control device 100, and is a device for achieving both energy saving improvement and productivity improvement.

[0019] The air conditioner 50 has a configuration in which air in the target space is sucked and cooled, and the cooled air is supplied to the target space. Specifically, it has a configuration in which heat exchange is performed between air and refrigerant by circulating the refrigerant between the air conditioner 50 and an outdoor unit (not shown), and the air is cooled. The outdoor unit has a configuration in which the refrigerant that has taken heat from the air releases the heat to the outside air.

[0020] The air conditioner 50 is provided with a heat exchange part (not shown) that cools the sucked air by heat exchange, and an air conditioner 50 fan (not shown) that sends out the heat-exchanged air. A heat exchange part and an air conditioner fan having a known configuration are used.

[0021] The air conditioner 50 preferably performs air conditioning so that the target space reaches the set temperature. In this embodiment, the case where the air conditioner 50 is installed in a corporate office will be described. Note that the air conditioner 50 may be installed in buildings other than offices. For example, it may be installed in a house or a classroom in a school. Also, the air conditioner 50 may be installed in means of transportation or the like other than buildings.

[0022] The air conditioner 50 has a configuration that can be communicably connected to the control device 100. Specifically, it is preferable that the air conditioner 50 is controlled based on a signal transmitted from the control device 100. The air conditioner 50 discharges conditioned air so that the temperature of the target space reaches the set temperature. The temperature of the conditioned air (hereinafter also referred to as the conditioning temperature) is preferably lower than the set temperature when the air conditioner 50 is started. Note that in this embodiment, it is preferable that the temperature of the target space reaches the set temperature at the start time of the company.

[0023] The outside air introduction unit 51 has a configuration that can be communicably connected to the control device 100. Specifically, it is preferable that the outside air introduction unit 51 is controlled based on a signal transmitted from the control device 100.

[0024] The outside air introduction unit 51 has a configuration that rotates an outside air fan (not shown) to cause outside air to flow into the target space to be air-conditioned or to cause indoor air to flow out to the outside air.

[0025] The outside air introduction unit 51 preferably causes the outside air to flow in when the temperature of the outside air is lower than a predetermined temperature or lower than the indoor temperature. Alternatively, the outside air introduction unit 51 preferably causes the outside air to flow in when the humidity of the outside air is lower than a predetermined humidity or lower than the indoor humidity.

[0026] By introducing outside air, the outside air introduction unit 51 can facilitate at least one of a decrease in the temperature of the target space and a decrease in the carbon dioxide concentration in the target space. The carbon dioxide concentration will be described later.

[0027] The target space is preferably the interior of a building that is to be air-conditioned. The control device 100 is an information processing device such as a server or computer that has a CPU (Central Processing Unit), ROM, RAM, input / output interfaces, etc. The control device 100 is connected to multiple air conditioners 50, an outside air intake unit 51, a camera, and measuring instruments in a manner that enables information communication. The number of air conditioners 50 and cameras connected to the control device 100 may be one or multiple units.

[0028] As shown in Figure 1, the control device 100 stores a program in its ROM, etc., that causes the CPU, ROM, RAM, and input / output interface to work together to function as at least an acquisition unit 101, a storage unit 102, an image estimation unit 103, an index estimation unit 104, a setting unit 105, a calculation unit 106, a judgment unit 107, and a control unit 108.

[0029] The acquisition unit 101 is connected to a camera (not shown) and is capable of receiving and acquiring captured image information and measurement information measured by measuring instruments (hereinafter also referred to as image information, etc.). The acquisition unit 101 has a configuration that acquires image information including the amount of clothing worn, activity level, and number of people in the room captured by the camera, as well as the room temperature and other information measured by measuring instruments.

[0030] The image information preferably includes information for estimating the amount of clothing worn by occupants, their activity level, and the number of people in the room. The amount of clothing refers to parameters indicating the type and number of garments worn by occupants. For example, it may include the sleeve length and the number of outer garments worn by occupants. Note that the amount of clothing may also include information other than that mentioned above.

[0031] Activity level refers to information indicating the activity status of occupants. Specifically, it is preferable that this includes information on occupants' activities, such as whether they are walking or sitting. The number of occupants refers to the number of people staying in the target space. The number of occupants may be calculated from image information, or it may be calculated using a scheduling system.

[0032] The measurement information should preferably include information for estimating the air conditioning indicators for occupants. For example, it is preferable to include indoor temperature, humidity, radiant temperature, and wind speed. The storage unit 102 is an information storage medium and has a configuration for storing image information and the like. Preferably, the stored information includes information acquired by the acquisition unit 101. The storage unit 102 may be a flash memory such as an SD memory card, or it may be another type of recording medium.

[0033] The image estimation unit 103 has a configuration that allows it to estimate the number of occupants, the amount of clothing worn, and the activity level of people staying in the target space, based on the acquired image information. The image estimation unit 103 may also estimate the amount of clothing worn and the activity level for each occupant included in the image information.

[0034] The indicator estimation unit 104 can estimate the air conditioning index (hereinafter also referred to as PMV value) of occupants based on their activity level and clothing level. In addition, the indicator estimation unit 104 can estimate the PMV value of occupants based on the number of people in the room, in addition to their activity level and clothing level. In this embodiment, the indicator estimation unit 104 has a configuration in which it estimates the PMV value by inputting the information described below into a learning model.

[0035] The information input to the learning model includes the work content, clothing information, indoor temperature, outdoor temperature and humidity, the set temperature of the air conditioner 50, and the number of people in the target space. Note that information other than the above may also be input to the learning model. Furthermore, the learning model is a model that has been trained using machine learning. For machine learning, known learning methods can be used.

[0036] The PMV value is a parameter calculated using a comfort equation with six variables: indoor temperature, humidity, radiant temperature, wind speed, amount of clothing worn, and activity level. In this embodiment, the PMV value is a parameter calculated using a comfort equation with the following elements as variables: indoor temperature, humidity, and radiant temperature included in the information on the indoor environment; wind speed included in the information on the outside environment; and amount of clothing worn and activity level included in the information on the occupants.

[0037] The PMV value ranges from -3 (cold) to +3 (hot). Statistically, approximately 95% of people feel comfortable when the PMV value is 0, and approximately 90% of people feel comfortable when the PMV value is between -0.5 and +0.5. It is preferable to control the air conditioning so that the PMV value falls within this predetermined range.

[0038] The setting unit 105 has a configuration that sets the target temperature, which is the target temperature of the room, based on the estimated PMV value. In addition to the target temperature, the setting unit 105 may also set the target humidity or the target carbon dioxide concentration, which is a predetermined target carbon dioxide concentration of the room.

[0039] The target temperature is preferably a temperature that is likely to improve the comfort or productivity of occupants, estimated based on the PMV (Primary Monetary Value) of the occupants. The target temperature may also be a predetermined temperature. Furthermore, the target temperature is preferably one that easily balances improved comfort or productivity with improved energy efficiency.

[0040] The target humidity is preferably a humidity level that is likely to improve the comfort or productivity of occupants, estimated based on the PMV values ​​of the occupants. The target humidity may also be a predetermined humidity level. Furthermore, the target humidity is preferably a temperature that easily balances improved comfort or productivity with improved energy efficiency.

[0041] Carbon dioxide concentration is a value that indicates the proportion of carbon dioxide in a room. Generally, lower carbon dioxide concentrations tend to increase worker productivity. Furthermore, introducing outside air tends to lower indoor carbon dioxide concentration. In other words, introducing outside air tends to increase worker productivity.

[0042] The calculation unit 106 has a configuration that calculates the energy consumption of the air conditioner 50 and the outside air intake unit 51. Furthermore, the calculation unit 106 can calculate the reduced energy consumption of the air conditioner 50 due to the introduction of outside air by the outside air intake unit 51.

[0043] The determination unit 107 has a configuration that determines whether to operate the air conditioner 50 and the outside air intake unit 51. Specifically, the determination unit 107 determines whether the outside air temperature is equal to or above the target temperature or indoor temperature set based on the PMV value. If the outside air temperature is equal to or above the target temperature or indoor temperature, the determination unit 107 determines not to perform outside air cooling and to perform only the air conditioning control described later. If the outside air temperature is below the target temperature or indoor temperature, it determines to perform outside air control or additional control described later.

[0044] Furthermore, the determination unit 107 has a configuration that determines whether the indoor temperature will reach the target temperature by introducing outside air alone. If the indoor temperature will reach the target temperature by introducing outside air alone, outside air control is performed. If the indoor temperature will not reach the target temperature by introducing outside air alone, additional control is performed.

[0045] In this embodiment, the determination unit 107 makes a decision based on temperature, but it may also make a decision based on something other than temperature. Specifically, the determination unit 107 determines whether the outside air humidity is equal to or greater than the target humidity or indoor humidity set based on the PMV value. If the outside air humidity is equal to or greater than the target humidity or indoor humidity, the determination unit 107 decides not to perform outside air cooling and to perform only the air conditioning control described later. If the outside air humidity is less than the target humidity or indoor humidity, it decides to perform outside air control or additional control described later.

[0046] In other words, the determination unit 107 can perform outside air cooling, air conditioning control, or additional control based on the outside air enthalpy calculated based on at least one of the outside air temperature and outside air humidity.

[0047] The control unit 108 has a configuration that controls the air conditioner 50 and the outside air intake unit 51. In this embodiment, it is preferable that the control unit 108 performs air conditioning control that controls only the air conditioner 50, additional control that controls both the air conditioner 50 and the outside air intake unit 51, and outside air control that controls only the outside air intake unit 51.

[0048] It is preferable that the air conditioning control controls at least one of the following: the set temperature, the amount of conditioned air, the start time of operation of the air conditioner 50, and the end time of operation of the air conditioner 50. Also, air conditioning control consumes more energy than outside air control.

[0049] In additional control, it is preferable to control both outside air control and air conditioning control. In additional control, outside air control is performed when the outside air temperature is lower than the target temperature or the indoor temperature. In additional control, air conditioning control is performed by introducing outside air, thereby limiting the energy consumption of the air conditioner 50 to an upper limit. In other words, the energy consumption of additional control is less than or equal to the energy consumption of air conditioning control. Additional control may also be performed when the outside air humidity is lower than the target humidity or the indoor humidity.

[0050] Outside air control is a control system that introduces outside air. Outside air control consumes less energy than air conditioning control. The energy consumption for air conditioning control, additional control, and outside air control will be explained with reference to Figure 2. Note that the target temperature for each control is the same. The vertical axis represents energy consumption. Vertical line 1 represents outside air control. Vertical line 2 represents additional control. Vertical line 3 represents air conditioning control.

[0051] The camera is installed to capture images of the interior of the building, including at least one camera and the amount of clothing the occupants are wearing. Furthermore, the camera is configured to transmit the captured image information to the control device 100. In this embodiment, it is preferable that the camera be able to capture images of all entrances and exits.

[0052] The camera may be an existing camera with camera functionality located within the building, or it may be incorporated into the control device 100, or it may be configured independently. In this embodiment, the case in which the camera is configured independently of the control device 100 will be described.

[0053] Furthermore, it is preferable that the camera be installed in the upper space so that it can overlook the room being filmed from above. Specifically, it is preferable that the camera be installed on the ceiling of the room being filmed. However, the camera may be installed in a location other than the ceiling of the room being filmed. In addition, a configuration other than a camera is also acceptable as long as it can determine the number of people in the building.

[0054] The measuring instrument is a device configured to measure the temperature of a room. In addition to the temperature, the measuring instrument may also measure the humidity and wind speed of the room. Description of the action Next, the operation of the air conditioning system 10 with the above configuration will be explained with reference to Figure 3. First, the air conditioner 50 will be described, second, the camera will be described, third, the control of the control device 100 will be described, and fourth, the learning method of the learning model will be described.

[0055] First, the air conditioner 50 draws in indoor air from the office by rotating an air conditioning fan (not shown). The air drawn in is the air from which heat has been radiated by the occupants and the air discharged from electronic equipment installed in the office.

[0056] The inhaled air is cooled in the heat exchange unit (not shown). Specifically, the inhaled air loses heat to the refrigerant circulating between it and the outdoor unit (not shown), causing its temperature to drop. The refrigerant, having lost heat, releases heat into the outside air in the outdoor unit. The refrigerant that has released heat then again absorbs heat from the inhaled air in the heat exchange unit.

[0057] The air cooled in the heat exchange section is sent into the office by an air conditioning fan (not shown). The air sent into the office is conditioned to ensure a comfortable environment for occupants based on the PMV value. The air sent into the office is then drawn back into the air conditioner 50.

[0058] The outside air intake unit 51 introduces outside air into the target space by rotating an outside air fan (not shown). The introduced outside air exchanges heat with the indoor air. The temperature of the indoor air decreases after heat exchange. In addition, the introduction of outside air reduces the indoor humidity and the indoor carbon dioxide concentration.

[0059] Next, the camera control will be explained. When power is supplied to the camera, it continues to photograph the target space. If a person in the building is photographed, the camera transmits the image information of the person to the control device 100. In other words, each time a person in the building is photographed, the camera transmits the image information of the person to the control device 100.

[0060] Next, the control in the control device 100 will be explained with reference to Figure 3. The acquisition unit 101 performs the process of acquiring image information, etc., at any time (S1). The image information, etc., may include one occupant or may include multiple occupants.

[0061] Image information acquired by the acquisition unit 101 is stored in the storage unit 102. Based on the stored image information, the image estimation unit 103 performs processing to estimate the number of occupants, the amount of clothing they are wearing, and their activity level (S2). The number of occupants may be acquired from the scheduling system.

[0062] After processing in S2, the indicator estimation unit 104 performs a process to estimate the PMV value for each occupant (S3). In this embodiment, the indicator estimation unit 104 estimates the PMV value using machine learning.

[0063] After the PMV value is estimated, the setting unit 105 performs a process to set the target temperature based on the estimated PMV value (S4). The PMV value used for the target temperature may be the PMV value of one person, or it may be the average of multiple PMV values.

[0064] Once the target temperature is set, the determination unit 107 performs a process to determine whether to introduce outside air based on the outside air temperature. Specifically, the determination unit 107 determines whether the outside air temperature is lower than the target temperature (S5).

[0065] If the answer is NO, the outside air control process is performed (S6). If the answer is YES, the determination unit 107 determines whether the indoor temperature will reach the target temperature by operating the outside air intake without operating the air conditioner 50 (S7).

[0066] If the answer to step S7 is YES, the control unit 108 performs outside air control (S8). In step S7, it is preferable that the control unit 108 controls the room temperature to reach the target temperature.

[0067] If the answer is NO, the control unit 108 performs additional control (S9). Specifically, the control unit 108 controls both the air conditioner 50 and the outside air intake unit 51. In this embodiment, the additional control preferably involves controlling the air conditioner 50 using the amount of energy consumed by the air conditioner 50 that is reduced by introducing outside air.

[0068] Next, we will discuss machine learning in the context of learning models. In this embodiment, the explanation applies to an example where machine learning of a learning model is performed in an information processing device different from the control device 100. The learning model that has undergone machine learning is stored in the storage unit 102 before processing by the control device 100.

[0069] Furthermore, a model that has undergone further machine learning after control by the control device 100 may be stored in the memory unit 102. In this case, the previously stored learning model is replaced by the learning model that has undergone further machine learning.

[0070] Furthermore, the machine learning of the learning model may be performed in different information processing devices as described above, or it may be performed in the control device 100. If machine learning is performed in the control device 100, the control device 100 will be equipped with a machine learning unit for performing machine learning. Alternatively, machine learning may be performed on one of the learning models in different information processing devices, and machine learning may be performed on the other in the control device 100.

[0071] In machine learning models, training data is used to determine if a person is the same person before and after they move. Specifically, training data may be used that determines the distance a person moves based on the distance estimated from preceding and succeeding frames of an image, or training data may be used that determines the same person based on similarity.

[0072] Regarding the specific machine learning methods used in the learning model, known supervised learning methods may be employed, and there are no limitations on the specific content of the computational processing in supervised learning. Similarly, regarding the method for creating the training data for the learning model, known methods may be used, and there are no limitations on the specific method of creation.

[0073] Description of effects According to the air conditioning system 10 with the above configuration, the comfort of occupants is likely to be improved by introducing outside air. In other words, the productivity of occupants is likely to be improved by introducing outside air.

[0074] Furthermore, introducing outside air may cause the temperature of the target space to rise. If the temperature of the target space exceeds a predetermined target temperature, the temperature of the target space can be lowered by consuming an amount of energy less than or equal to the amount of energy consumed by introducing outside air. In other words, the energy-saving effect of the air conditioner 50 is likely to improve.

[0075] Furthermore, introducing outside air tends to lower the carbon dioxide concentration in the target space. Lower carbon dioxide concentrations tend to improve the comfort level of occupants. In other words, introducing outside air tends to improve the productivity of occupants.

[0076] Furthermore, the control unit 108 can perform a variety of controls by performing additional control processing, at least one of the following: increasing the flow velocity of the air conditioning airflow and lowering the set temperature. In other words, it is easier to achieve both improved productivity and improved energy saving effects.

[0077] Furthermore, the inclusion of the image estimation unit 103 allows for the estimation of the number of occupants in a room. Using the estimated number of occupants, the indicator estimation unit 104 can estimate the air conditioning index for each occupant. Additionally, by estimating the air conditioning index using the estimated number of occupants, the indicator estimation unit 104 can calculate a highly accurate PMV value.

[0078] Furthermore, the image estimation unit 103 can estimate the amount of clothing worn by the person staying there, and the index estimation unit 104 can estimate the air conditioning index using the estimated amount of clothing. By estimating the PMV value using the estimated amount of clothing, the index estimation unit 104 can calculate a highly accurate PMV value.

[0079] Furthermore, the indicator estimation unit 104 can estimate the predicted first temperature using machine learning. By estimating the air conditioning index using the estimated predicted first temperature, the indicator estimation unit 104 can easily calculate a highly accurate PMV value.

[0080] It should be noted that the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. For example, the present invention is not limited to those applied to the embodiments described above, but may also be applied to embodiments that combine these embodiments as appropriate, and is not particularly limited.
