The operation support system 1 supports the operation of the heat supply equipment 2 by setting the new operating conditions 53.

[0010] Equipment refers to machinery installed in buildings such as factories. The term "equipment" is a general term encompassing machinery, instruments, and fixtures. Heat supply equipment 2 refers to machinery and fixtures that supply heat to load equipment LE. Heat supply equipment 2 comprises at least one heat source device 21 that heats the heat transfer medium HM supplied to load equipment LE. Heat supply equipment 2 supplies heat to load equipment LE using the heated heat transfer medium HM.

[0011] The heat supply device 2 uses a primary utility to heat a heat medium HM as a secondary utility.

The heat medium refers to an energy source or fluid necessary for industrial activities. Examples of the heat medium HM output from the heat supply device 2 include steam, heat medium oil, hot water, and cold water.

[0012] The heat source device 21 has an air source heat pump. The air source heat pump pumps up (absorbs heat) heat from the air and transfers (releases heat) the pumped-up heat to the heat medium HM, thereby heating the heat medium HM. The air source heat pump can heat service water to produce hot water.

[0013] The load equipment LE uses the heat medium HM (hot water) output from the heat supply device 2. The load equipment LE uses the heat medium HM as a heat source for, for example, various production processes, treatment processes, hot water supply, or air conditioning.

[0014] In addition, the load equipment LE may include medical mechanical appliances used within a series of processes from the acceptance to the discharge of the object to be washed and sterilized, washing mechanical appliances used within a series of processes from the collection to the shipment of the objects to be washed, and food and beverage manufacturing mechanical appliances used within a series of processes from the acceptance of raw materials to the storage of products.

[0015] Examples of medical mechanical appliances include washers and sterilizers. Examples of washers include vacuum boiling washers and ultrasonic washers.

Establishment 3 where goods are produced, etc., includes factories 4. The load equipment LE is installed at factories 4. Examples of factories 4 include food factories, beverage factories, metal product factories, plastic product factories, textile factories, and laundry factories.

[0019] Furthermore, a factory 4 is not required to be established at business establishment 3, which provides the services. The business conducted at business establishment 3 may include public health services. Examples of public health services include hospitals, clinics, and public health centers. Business establishment 3 may also include a school lunch center.

[0020] In the example shown in Figure 1, a certain business operator has three business establishments 3. Business establishments 3 include the first business establishment 3A, the second business establishment 3B, and the third business establishment 3C. A factory 4 is located in the second business establishment 3B. The factory 4 located in the second business establishment 3B includes the first factory 4A and the second factory 4B. Alternatively, a factory 4 may be located in either the first business establishment 3A or the third business establishment 3C, or both.

[0021] The heat supply equipment 2 is installed in both the first factory 4A and the second factory 4B. Data collection terminals 7 are installed in both the first factory 4A and the second factory 4B. Data collection terminals 7 is a general term for devices used for data collection at the business site 3.

[0022] The driving support system 1 comprises a sensor group consisting of one or more environmental sensors 5 installed in the heat supply equipment 2, a controller 61 that controls the heat source device 21 according to required operating conditions 53, a communication network 8 for transmitting information, and an information processing device 6 configured to acquire environmental information 51 detected by the environmental sensors 5 and operating information 52 generated by the controller 61 via the communication network 8.

[0023] The environmental sensor 5 detects environmental information of the heat supply equipment 2. Environmental information of the heat supply equipment 2 refers to the environmental state or conditions of the space in which the heat supply equipment 2 operates. The environmental information of the heat supply equipment 2 includes environmental information of the business establishment 3 (factory 4) where the heat supply equipment 2 is installed. The environmental information includes physical parameters of the heat supply equipment 2 and its surroundings. Some of the detection data from the environmental sensor 5 is used for the operation or control of the heat supply equipment 2. Examples of environmental sensors 5 include temperature sensors, humidity sensors, pressure sensors, water level sensors, flow rate sensors, electrical conductivity sensors (EC sensors), power sensors, distance sensors, image sensors, and force sensors.

[0024] The environmental sensor 5 is connected to the controller 61 of the heat supply equipment 2 and the controller 61 of the data collection terminal 7, respectively.

[0025] Figure 2 is a schematic diagram showing the heat supply equipment 2 and load equipment LE according to the first embodiment. The heat supply equipment 2 and load equipment LE are installed inside the factory building (factory building) of the factory 4. A work area WA where workers P perform their duties is provided inside the factory building. Workers P perform tasks such as using or managing the load equipment LE. The work area WA may be separated from the installation location of the load equipment LE. Part or all of the load equipment LE may be located inside the work area WA. In one example, the work area WA is configured as a closed room from the outside of the factory building. In other examples, the work area WA may be a space with open windows and doors, or a space in which part of the room is open to the outside.

[0026] The heat supply equipment 2 includes one or more heat source devices 21. Each heat source device 21 has an air-source heat pump with a refrigerant evaporator 211 installed in the work area WA. Specifically, the heat source device 21 is a vapor compression type heat pump including a refrigerant evaporator 211, a refrigerant condenser 212, a refrigerant compressor 213, and an expansion valve 214, wherein the refrigerant evaporator 211 is configured to evaporate the refrigerant using air as a heat source. The refrigerant evaporator 211, refrigerant condenser 212, refrigerant compressor 213, and expansion valve 214 are connected by a refrigerant circulation line 215 that circulates the refrigerant.

[0027] The refrigerant evaporator 211 of the heat source device 21 utilizes the air of the work area WA as a heat source. For this purpose, at least the air intake and discharge port of the refrigerant evaporator 211 are located in the work area WA. The refrigerant evaporator 211 evaporates the refrigerant by heat exchange between the air drawn in from the air intake port and the refrigerant. The refrigerant evaporator 211 releases the air, whose temperature has been lowered by the heat exchange, from the discharge port. As a result, when the heat source device 21 is in operation, a cooling effect is obtained as the air in the work area WA is cooled by the refrigerant evaporator 211.

[0028] In the example in Figure 2, the heat transfer medium HM is water (water). In the example in Figure 2, the air-source heat pump is, for example, a circulating water heating system. The heat supply equipment 2 includes a heat source device 21 and a water tank 22 connected by a water line 23. The water line 23 is a flow path for the water (water), which is the heat transfer medium HM. In this specification, "line" refers to any line through which fluids can flow, such as a flow path, route, or pipeline. The heat source device 21 heats the water by transferring the heat pumped from the air to the refrigerant, which is the heat transfer medium HM, along with the heat of compression in the refrigerant condenser 212. The heated water is stored in the water tank 22. The water line 23 connects the water tank 22 to the load equipment LE. The water (heat transfer medium HM) stored in the water tank 22 is supplied to the load equipment LE via the water line 23. The load equipment LE either uses the supplied water as is or utilizes the heat extracted from the water. A pump for circulating the heat transfer medium HM may be provided in the water line 23.

[0029] The environmental sensor 5 is installed in the heat supply equipment 2. The environmental sensor 5 can be installed in one or more of the heat source device 21, the water line 23, and the water tank 22. The environmental sensor 5 installed in the heat supply equipment 2 includes a temperature sensor, a flow rate sensor, a power sensor, etc. The environmental sensor 5 is also installed in the work area WA. The environmental sensor 5 installed in the work area WA includes, for example, a temperature sensor and a humidity sensor. The environmental sensor 5 may also be installed in the load equipment LE.

[0030] The controller 61 of the heat supply equipment 2 has the function of controlling the operation of the heat supply equipment 2 and controlling data collection. The controller 61 is mainly used for autonomous operation control of the heat source device 21. The controller 61 controls the operation of the heat source device 21 based on the operating conditions 53 of the heat source device 21, which will be described later. The controller 61 of the heat supply equipment 2 is connected to environmental sensors 5 installed in the heat source device 21, the water line 23, or the water tank 22. The controller 61 of the heat supply equipment 2 may also be configured as part of a data collection terminal 7 that is specialized for collecting information from environmental sensors 5 in the work area WA and load equipment LE.

[0031] As shown in Figure 1, the controller 61 is incorporated into the heat supply equipment 2, the load equipment LE, and the data acquisition terminal 7. Examples of the controller 61 include a microcomputer 61A and a programmable logic controller 61B (PLC). The microcomputer 61A is an example of the controller 61 incorporated into the data acquisition terminal 7.

[0032] The controller 61 of the heat supply equipment 2 uses environmental information collected from the environmental sensor 5 to control the operation of the heat supply equipment 2 and records it for operational management.

[0033] The controller 61 of the data collection terminal 7 is connected to each of the multiple environmental sensors 5 scattered throughout the business premises 3. The controller 61 of the data collection terminal 7 is connected to multiple environmental sensors 5 of different types.

[0034] The controller 61 generates operating information 52 for the heat source device 21. The controller 61 may also generate the operating information 52 for the heat source device 21 based on the detection data of the environmental sensor 5.

[0035] [2] Hardware configuration of the information processing device As shown in Figure 1, the driver assistance system 1 has a plurality of information processing devices 6. The information processing devices 6 include a controller 61, an edge computer 62, a gateway 63, a guest computer 64, and a host computer 65.

[0036] Figure 3 is a hardware configuration diagram showing an information processing device 6 according to an embodiment. The information processing device 6 includes a computer 10. The controller 61, edge computer 62, gateway 63, guest computer 64, and host computer 65 each include the computer 10. The computer 10 has a processor 11, a storage device 12, a communication interface 13, and an input / output interface 14. The information processing device 6 also has a power supply (not shown).

[0037] The processor 11 includes a CPU (Central Processing Unit). The processor 11 may also include a GPU (Graphics Processing Unit). The storage device 12 includes a recording medium on which computer programs and data are recorded in a readable format by the processor 11. The storage device 12 includes onboard system memory such as RAM (Random Access Memory) or ROM (Read Only Memory), high-capacity flash memory such as an SD card or USB memory, and high-capacity storage such as an HDD (Hard Disk Drive) or SSD (Solid State Drive).

[0038] The communication interface 13 communicates via the communication network 8. Computer 10 sends data to an external computer via the communication network 8. Computer 10 receives data from an external computer via the communication network 8. Computer 10 connects to an external device via the input / output interface 14.

[0039] The communication network 8 is a general term for communication paths and devices that enable communication so that multiple computers 10 can send and receive information. Examples of communication networks 8 include local area networks (LANs), wide area networks (WANs), and commercial networks such as the Internet. A local area network may be a wired LAN or a wireless LAN. A wide area network may include mobile lines or satellite communication lines.

[0040] The storage device 12 stores various software programs. The storage device 12 stores a driver assistance application program 100 according to an embodiment. The processor 11 reads the software program from the storage device 12, loads it into system memory, and executes processing according to the software program. That is, the processor 11 can be considered to have multiple functional units. The functions of the processor 11 are realized by the software program. The software program may be distributed to the computer 10 via the communication network 8.

[0041] A software program that implements a specific function on a computer is called an application or engine (hereinafter referred to as "application, etc."), and the functional unit of an application, etc. is called a module. An application, etc. may be installed on a computer as a single software package containing all functions, but it is preferable to install it on a computer as individual software modules, each containing a functional unit. When the functional units of an application, etc. are modularized, updates become easier when functional modifications are made. An application that runs on an edge computer 62 is sometimes called an edge application.

[0042] The environmental sensor 5 is connected to the input / output interface 14 of the controller 61. Multiple environmental sensors 5 are connected to one controller 61. The controller 61 collects environmental information 51 from the environmental sensors 5 in real time. The communication interface 13 of the controller 61 transmits the real-time environmental information 51 and real-time operational information 52 to the edge computer 62 via the communication network 8 (LAN).

[0043] The controller 61 of the heat source device 21 can function not only as a local controller for the air-source heat pump, but also as a system controller for controlling peripheral equipment (such as water pumps and water supply valves).

[0044] The edge computer 62 is installed in factory 4. One or more edge computers 62 are installed in each factory 4. The communication interface 13 of the edge computer 62 communicates with each of the multiple controllers 61 belonging to factory 4 where the edge computer 62 is located, via the communication network 8 (LAN). The edge computer 62 receives environmental information 51 and operational information 52 from the controllers 61 via the communication network 8.

[0045] The edge computer 62 has approximately 5GB of onboard memory as storage device 12 so that it can store a sufficient amount of information. The edge computer 62 may also have an AI engine (Neural Network Processing Unit: NPU) so that it can perform the training and inference phases in machine learning.

[0046] Gateway 63 constitutes a connection node between the local area network and the internet and has performance and specifications equivalent to that of the edge computer 62. Gateway 63 is installed at business establishment 3. One or more gateways 63 are installed at a single business establishment 3. The communication interface 13 of gateway 63 communicates with each of the multiple edge computers 62 belonging to business establishment 3 where gateway 63 is located, via the communication network 8 (LAN). Gateway 63 receives environmental information 51 and operational information 52 from the edge computers 62 via the communication network 8. If the factory 4 located at business establishment 3 is a single building, the edge computer 62 and gateway 63 may be integrated and configured as a single computer.

[0047] The guest computer 64 is located outside of the business premises 3. For example, the guest computer 64 is installed at a regional base of a service provider that undertakes tasks such as monitoring the status and maintenance of the heat supply equipment 2 installed at business premises 3. One guest computer 64 is installed at each management base. The guest computer 64 includes a local server. The communication interface 13 of the guest computer 64 communicates with the gateway 63 belonging to business premises 3 via the communication network 8 (Internet). The guest computer 64 receives environmental information 51 and operational information 52 from the gateway 63 via the communication network 8. If a guest computer 64 is not installed, the gateway 63 and the host computer 65 (described later) will be connected via the communication network 8.

[0048] The host computer 65 is located outside of the business premises 3. The host computer 65 is installed, for example, at the central hub of a service provider. The host computer 65 includes a cloud server. The communication interface 13 of the host computer 65 communicates with each of the multiple guest computers 64 via the communication network 8 (Internet). The host computer 65 receives environmental information 51 and operational information 52 from the guest computers 64 via the communication network 8.

[0049] [3] Hierarchical structure of information processing equipment Figure 4 is a diagram illustrating the hierarchical structure of the information processing device 6 according to the embodiment. The multiple information processing devices 6 have a hierarchical structure that transmits environmental information detected by the environmental sensor 5 and operational information generated by the controller 61 from the downstream side to the upstream side. Of the multiple information processing devices 6, the controller 61 to which the environmental sensor 5 is connected is the most downstream (lower layer, lower level) information processing device 6, followed by the edge computer 62 as the next downstream information processing device 6, followed by the gateway 63 as the next downstream information processing device 6, followed by the guest computer 64 as the next downstream information processing device 6, and the host computer 65 as the most upstream (upper layer, higher level) information processing device 6.

[0050] The information processing devices 6 are connected to each other via a communication network 8. Inside the building, a local area network is used as the communication network 8, while outside the building, a commercial wide area network such as an internet connection or a mobile network is used as the communication network 8.

[0051] Environmental information 51 is detected by the environmental sensor 5. The controller 61, which is a lower-level information processing device in the hierarchical structure, acquires the environmental information 51 from the environmental sensor 5. The environmental information 51 detected by the environmental sensor 5 and collected by the controller 61 is transmitted from the controller 61 to the edge computer 62 via the communication network 8. Operational information 52 generated by the controller 61 is also transmitted from the controller 61 to the edge computer 62 via the communication network 8. The environmental information 51 and operational information 52 transmitted to the edge computer 62 are then transmitted from the edge computer 62 to the gateway 63 via the communication network 8. The environmental information 51 and operational information 52 transmitted to the gateway 63 are then transmitted from the gateway 63 to the guest computer 64 via the communication network 8. The environmental information 51 and operational information 52 transmitted to the guest computer 64 are then transmitted from the guest computer 64 to the host computer 65 via the communication network 8.

[0052] The controller 61 is a lower-level information processing unit in the hierarchical structure. The edge computer 62, gateway 63, and guest computer 64 are intermediate information processing units in the hierarchical structure. The host computer 65 is a higher-level information processing unit in the hierarchical structure.

[0053] The lower-level information processing unit functions as an IoT device to which the environmental sensor 5 is connected. The lower-level information processing unit can transmit various environmental and operational information to the intermediate information processing unit. The intermediate information processing unit functions as a relay between the lower-level information processing unit and the higher-level information processing unit. The intermediate information processing unit can receive various environmental and operational information from the lower-level information processing unit and transmit various environmental and operational information to the higher-level information processing unit. The higher-level information processing unit can receive various environmental and operational information from the intermediate information processing unit.

[0054] [4] Software configuration of the information processing device Figure 5 is a functional block diagram showing an information processing device 6 according to an embodiment. The information processing device 6 includes an information processing module 31, an operating condition generation module 32, an operating condition modification module 33, a UI provision module 34, an information storage platform 35, and a database 36. The database 36 may be a group of databases that handle a wide variety of information, or it may be a component of the information storage platform 35.

[0055] A user terminal 40 is connected to an information processing device 6. Examples of user terminals 40 include personal computers, tablet devices, and smartphones. The user terminal 40 includes a display device such as a liquid crystal display or an organic EL display.

[0056] The multiple information processing devices 6 (61, 62, 63, 64, 65) each have an information processing module 31, an operating condition generation module 32, an operating condition modification module 33, a UI provision module 34, an information storage platform 35, and a database 36 in any one or more layers. That is, each of the information processing module 31, the operating condition generation module 32, the operating condition modification module 33, the UI provision module 34, the information storage platform 35, and the database 36 can be a functional unit in any one or more layers of the multiple information processing devices 6 (61, 62, 63, 64, 65).

[0057] These functional units are realized by causing the computer 10 to perform information processing according to the driver assistance application program 100 according to the embodiment. In other words, the driver assistance application program 100 has program modules for operating the computer 10 as an information processing module 31, an operating condition generation module 32, an operating condition change module 33, and a UI provision module 34, respectively. When the computer 10 executes the program module of the information processing module 31, the information processing of the information processing module 31 as a functional unit is realized. When the computer 10 executes the program module of the operating condition generation module 32, the information processing of the operating condition generation module 32 as a functional unit is realized. When the computer 10 executes the program module of the operating condition change module 33, the information processing of the operating condition change module 33 as a functional unit is realized. When the computer 10 executes the program module of the UI provision module 34, the information processing of the UI provision module 34 as a functional unit is realized.

[0058] In one example, the operating condition generation module 32 and the operating condition modification module 33 are preferably functional units of the edge computer 62. The information processing module 31 is preferably functional unit of the edge computer 62 or gateway 63, and the UI provision module 34, information storage platform 35, and database 36 are preferably functional units of the host computer 65. When the operation support system 1 is completed within the factory building (factory building) of the factory 4 at the request of the operations manager of the business site 3, all of the modules, platforms, and databases may be functional units of the edge computer 62.

[0059] <4-1> Information Processing Module The information processing module 31 performs predefined information processing on the acquired environmental information 51 and operational information 52. The information processing performed by the information processing module 31 includes, for example, batch processing to adjust the time-series environmental information 51 and operational information 52 to the required time granularity. The information processing performed by the information processing module 31 also includes, for example, grouping processing to integrate multiple environmental information 51 and operational information 52 of different types into an information set linked to the hierarchical level of industrial activity.

[0060] <4-1-1> Generation process of environmental information and operational information The information processing module 31 acquires and stores environmental information 51 from the environmental sensor 5 at predetermined sampling intervals. The information processing module 31 has functions such as A / D conversion to convert analog signals from the environmental sensor 5 into digital signals, substitution of A / D values ​​with measurement sample values, selection of measurement sample values, moving average function of measurement sample values, and period or frequency measurement function of pulse signals, and uses these functions to calculate confirmed measurement values ​​in real time.

[0061] The information processing module 31 acquires and stores real-time operation information 52 from the controller 61 at predetermined sampling intervals. For example, the controller 61 transmits an "operating" signal when the heat source device 21 is operating and a "stopped" signal when it is stopped. The information processing module 31 uses the "operating" signal received via the input / output interface 14 to measure the uptime (actual operating time information) of the heat source device 21. The information processing module 31 also uses the "stopped" signal received via the input / output interface 14 to measure the downtime (non-operating time information) of the heat source device 21.

[0062] The time granularity of the real-time environmental information 51 and real-time operational information 52 depends on the sampling interval or recording interval, and is generally quite fine (for example, the latest values ​​are updated at intervals of 10ms to 1s). The information processing module 31 transmits the environmental information 51, along with an identification number (measurement item ID, device ID, location ID, etc.) and the update time, to the higher-level information processing device 6.

[0063] <4-1-2> Batch Processing Real-time environmental information 51 and real-time operational information 52 are time-series data that are generated sequentially over time in the information processing module 31. Batch processing refers to the process of adjusting the time-series environmental information 51 and operational information 52 to the required time granularity. Time granularity is an indicator that represents the degree of fineness of time, and can be selected from, for example, seconds, minutes, hours, or days.

[0064] <4-1-3> Grouping process Grouping refers to the process of integrating multiple types of environmental and operational information (environmental information 51, batch environmental information, operational information 52, batch operational information) into an information set linked to the hierarchical level of industrial activity. As shown in Figure 4, the hierarchical level of industrial activity includes one or more levels from among the machine level, machine group level, cell level, line level, building level, and business establishment level.

[0065] <4-2> Information Storage Platform The information storage platform 35 stores various types of information, such as numerical data and images, and also provides a foundational environment for operating software (engines, applications) and hardware. The information storage platform 35 is composed of, for example, an operating system and a database, enabling centralized management of diverse big data and facilitating the smooth processing and utilization of information.

[0066] Figure 6 is a schematic diagram showing an example of environmental information 51 and operational information 52 according to the first embodiment. The information storage platform 35 stores environmental information 51 and operational information 52 that have undergone prescribed information processing by the information processing module 31, as well as various registered information registered via the input device.

[0067] <4-2-1>Environmental information Environmental information 51 includes one or more of the following information for the work area WA: ambient temperature information 511, ambient humidity information 512, and discomfort index information 513. The ambient temperature information 511, ambient humidity information 512, and discomfort index information 513 for the work area WA each serve as an indicator of the comfort level of the working environment for worker P in the work area WA. Environmental information 51 may also include information on the temperature of the heat transfer medium HM at predetermined locations in the water supply line 23 and water supply tank 22, and the temperature of the heat transfer medium HM in the load equipment LE.

[0068] The ambient temperature information 511 is information about the temperature value obtained by the temperature sensor, which is the ambient sensor 5. The ambient temperature information 511 includes the temperature of the work area WA (room temperature). The ambient humidity information 512 is information about the humidity value (relative humidity) obtained by the humidity sensor, which is the ambient sensor 5. The ambient humidity information 512 includes the relative humidity (room humidity) of the work area WA. The ambient humidity information 512 may also be absolute humidity.

[0069] The discomfort index information 513 is information on the discomfort index value calculated from the temperature value information obtained by the temperature sensor, which is an environmental sensor 5, and the humidity value information (relative humidity) information obtained by the humidity sensor, which is also an environmental sensor 5. The discomfort index information 513 includes the discomfort index of the work area WA (indoor environment discomfort index). The discomfort index is calculated by multiplying the dry-bulb temperature (air temperature) by T d If the temperature is (°C) and the humidity is H (%), it is calculated using the following formula. 0.81T d +0.01H(0.99T d -14.3) +46.3 The dry-bulb temperature may be the temperature value from the ambient temperature information 511. The humidity may be the humidity value from the ambient humidity information 512.

[0070] In addition, environmental information 51 may include WBGT (Wet Bulb Globe Temperature) as an indicator of comfort.

[0071] <4-2-2> Operation Information The operational information 52 includes one or more of the following information: heat output information 521 of the heat source device 21, operating frequency information 522, and operating number information 523. The operational information 52 is determined by the operating conditions 53 of the heat source device 21 and is an index indicating the amount of heat output at the heat supply equipment 2 (heat source device 21), as well as an index indicating the amount of heat input that the heat supply equipment 2 (heat source device 21) draws from the work area WA.

[0072] The heat output information 521 is information about the amount of heat that the heat source device 21 provides (outputs) to the heat transfer medium HM. The heat output information 521 can be expressed, for example, as the amount of heat output per unit time (J) or as an index value indicating the amount of heat output. When the flow rate of the heat transfer medium HM (water) is kept constant, the temperature of the heat transfer medium HM (hot water outlet temperature) can be used as the index value for the heat output information 521.

[0073] The operating frequency information 522 indicates how often the heat source device 21 performs heat output operations. The operating frequency information 522 can be expressed, for example, as the number of transitions from a stopped state to an operating state (startup count) that occur per unit time.

[0074] The operating unit information 523 indicates the number of heat source devices 21 operating simultaneously when the heat supply equipment 2 is equipped with multiple heat source devices 21. The operating unit information 523 may be the numerical value of the number of operating heat source devices 21 themselves, or it may be shown as an index value, such as the ratio of the operating unit to the base unit. If the total number of heat source devices 21 equipped in the heat supply equipment 2 is set as the base unit, the ratio will be the operating rate of the heat source devices 21 in the heat supply equipment 2. Note that the operating rate referred to here is the instantaneous operating rate and is distinct from the time operating rate, which is the ratio of operating time to load time.

[0075] <4-3> Operating Condition Generation Module The operating condition generation module 32 generates new operating conditions 53 for the heat source device 21 using the environmental information 51 and operating information 52 stored in the information storage platform 35. In other words, the operating condition generation module 32 generates new operating conditions 53 using the time-series environmental information 51 obtained from the work area WA and the time-series operating information 52 obtained from the heat source device 21.

[0076] Operating conditions 53 are conditions (rules) for controlling the operation of the heat source device 21. Operating conditions 53 include, for example, setting the water level of the water tank 22. Based on the water level setting of the water tank 22, the controller 61 controls the start and stop operation of the heat source device 21 so that the water level of the water tank 22 is maintained at or above the set value. Operating conditions 53 include, for example, setting the water temperature of the water tank 22 (i.e., setting the temperature of the heat transfer medium HM). Based on the water temperature setting, the controller 61 controls the start and stop operation of the heat source device 21 so that the water temperature of the water tank 22 is maintained at or above the set value. Operating conditions 53 include, for example, setting the rotational speed (load factor) of the refrigerant compressor 213 and the number of heat source devices 21 to be operated simultaneously. Based on the operating conditions 53 of the heat source device 21, the controller 61 controls, for example, the rotational speed (load factor) of the refrigerant compressor 213 and the number of heat source devices 21 to be operated.

[0077] Figure 7 is a diagram illustrating the process of generating operating conditions 53. Figure 7 shows the contents of environmental information 51, the new operating conditions 53, and the changes in operating information 52 caused by the new operating conditions 53. As shown in Figure 7, the operating condition generation module 32 compares the time-series environmental information 51 with the reference range 54 of the environmental information 51 and generates new operating conditions 53 according to the comparison result. The new operating conditions 53 are set in the heat source device 21 (controller 61), which results in a change in the operating information 52 of the heat source device 21.

[0078] Specifically, if the value of environmental information 51 is within the preset reference range 54 for the work area WA, the current operating condition 53A is maintained. The operating condition generation module 32 maintains the current operating condition 53A if the value of environmental information 51 is within the reference range 54. Operating condition 53A is the operating condition that maintains the operating level of the heat source device 21.

[0079] If the value of environmental information 51 is within the reference range 54, the amount of heat absorbed from the work area WA by the heat source device 21 and the amount of heat generated in the work area WA are appropriately balanced, and the comfort level of the work area WA is sufficiently high. Therefore, the comfort level of the work area WA is maintained by maintaining the operating level of the heat source device 21.

[0080] If the value of environmental information 51 exceeds the upper limit 541 of the pre-set reference range 54 for the work area WA, the newly generated operating conditions 53 include operating conditions 53 that upgrade one of the operating conditions 52. In other words, if the value of environmental information 51 exceeds the upper limit 541 of the reference range 54, the operating conditions generation module 32 generates new operating conditions 53B that upgrade one of the operating conditions 52.

[0081] If the value of environmental information 51 exceeds the upper limit of standard range 54, which is 541, it is considered that the amount of heat absorbed from the work area WA by the heat source device 21 is insufficient compared to the amount of heat generated in the work area WA (or the amount of heat input to the work area WA from the outside), and the comfort level of the work area WA is deteriorating. Therefore, by increasing the operating level of the heat source device 21 and increasing the amount of heat absorbed (cooling effect) by the heat source device 21, the balance between the amount of heat absorbed and the amount of heat generated will be optimized.

[0082] If the value of environmental information 51 falls below the lower limit 542 of the reference range 54, the newly generated operating condition 53 will include an operating condition 53C that lowers any of the operating conditions 52. In other words, the operating condition generation module 32 generates a new operating condition 53C that lowers any of the operating conditions 52 if the value of environmental information 51 falls below the lower limit 542 of the reference range 54.

[0083] If the value of environmental information 51 falls below the lower limit of 542 in the standard range 54, it is considered that the amount of heat absorbed from the work area WA by the heat source device 21 is excessive compared to the amount of heat generated in the work area WA, and the comfort level of the work area WA is deteriorating. Therefore, by lowering the operating level of the heat source device 21 and reducing the amount of heat absorbed (cooling effect) by the heat source device 21, the balance between the amount of heat absorbed and the amount of heat generated is optimized.

[0084] For example, suppose that during the summer, the environmental information 51 exceeded the upper limit of 541, and as a result of increasing the cooling effect of the heat pump and continuing to operate, the value of environmental information 51 decreased and fell below the lower limit of 542. This can be used as a trigger to reduce the cooling effect of the heat pump and adjust the environmental information 51 to the standard range of 54.

[0085] Figure 8 illustrates an example of a reference range 54 for environmental information 51. The reference range 54 is not particularly limited, but can be set to the range shown in Figure 8, for example. In the example in Figure 8, if environmental information 51 is environmental temperature information 511, the reference range 54 for environmental temperature is 18°C ​​to 28°C, according to the Office Hygiene Standards Regulations. Therefore, the upper limit 541 for environmental temperature is 28°C, and the lower limit 542 is 18°C. In the example in Figure 8, if environmental information 51 is environmental humidity information 512, the reference range 54 for environmental humidity is 40% to 60%. This is because indoor humidity between 40% and 60% is considered to be within a range where discomfort is not felt. Therefore, the upper limit 541 for environmental humidity is 60%, and the lower limit 542 is 40%. In the example in Figure 8, if environmental information 51 is discomfort index information 513, the reference range 54 for discomfort index is 60 to 70. The discomfort index is such that a score of 60-65 indicates no discomfort, and a score of 65-70 indicates comfort. Comfort levels decrease as the score falls outside this range. Therefore, the upper limit of the discomfort index is 541, which corresponds to a score of 70, and the lower limit is 542, which corresponds to a score of 60.

[0086] <4-3-1> Operating conditions for improving operational information An example of generating operating conditions 53B that prioritize any of the operating information 52 based on the reference range 54 in Figure 8 will be explained. If the environmental information 51 of the work area WA exceeds the upper limit 541, the operating condition generation module 32 generates new operating conditions 53B, such as a combination of one or more of the following.

[0087] <4-3-1-1> Upgrade of thermal output information The operating condition generation module 32 generates new operating conditions 53B, which are operating conditions that upgrade the heat output information 521. One way to upgrade the heat output information 521 is to increase the rotational speed of the refrigerant compressor 213 without changing the flow rate of the heat transfer medium HM sent from the heat source device 21 (from the current setting), thereby increasing the heat output of the heat pump (i.e., the hot water temperature). This increases the amount of heat absorbed in the refrigerant evaporator 211, and the temperature and humidity of the cold air coming out of the fan of the refrigerant evaporator 211 decrease. As a result, the temperature, humidity, and discomfort index of the work area WA decrease.

[0088] <4-3-1-2> Prioritizing higher operating frequency The operating condition generation module 32 generates new operating conditions 53B, which increase the operating frequency information 522. For example, for load equipment LE that generates hot water demand, the tank water level setting for starting heating operation is changed to a higher level than usual. In order to maintain the water level in the water tank 22 at a high level even when the hot water demand is low, the operating frequency of the refrigerant compressor 213 per unit time increases (the operating frequency information 522 increases). As the operating frequency of the heat source device 21 increases, the amount of heat removed from the surrounding air of the work area WA increases, and the temperature, humidity, and discomfort index of the work area WA decrease. Also, for load equipment LE that generates heat demand, the water return temperature for starting heating operation is changed to a higher level than usual. In order to maintain the water return temperature at a high level even when the heat demand is low, the operating frequency of the refrigerant compressor 213 per unit time increases.

[0089] As a concrete example of tank water level settings, let's assume that with the current settings, when hot water demand is low, the available hot water storage amount equivalent to the difference between the lower and upper water levels is consumed in 45 minutes and hot water is supplied in 15 minutes. If the upper water level setting is lowered (or the lower water level setting is raised) to reduce the available hot water storage amount to 1 / 3, the cycle of 15 minutes of consumption + 5 minutes of hot water supply will be repeated 3 times. In other words, the operating frequency per hour increases from 1 to 3 times, so the opportunities to cool the work area WA triple. If the operating frequency of the heat source device 21 is low, the working environment is likely to deteriorate (the room temperature rises excessively when stopped, and does not cool down easily when running), so it is better to increase the operating frequency to reduce the temperature difference.

[0090] <4-3-1-3> Ranking of the number of operating units The operating condition generation module 32 generates new operating conditions 53B, which are higher-level operating conditions than the operating unit information 523. For example, without changing the rotational speed (load factor) of the refrigerant compressor 213 of the first heat source unit 21, the second heat source unit 21 is started at the same load factor as the first unit. By increasing the number of operating heat source units 21, the amount of heat removed from the surrounding air of the work area WA increases, and the temperature, humidity, and discomfort index of the work area WA decrease.

[0091] <4-3-2> Operating conditions for lowering operational information To lower any of the operational information 52, the operational condition 53C should be set in the opposite direction to the condition used when raising any of the operational information 52.

[0092] <4-3-2-1> Lowering of thermal output information The operating condition generation module 32 generates new operating conditions 53B that reduce the thermal output information 521. One way to reduce the thermal output information 521 is to lower the rotational speed of the refrigerant compressor 213 without changing the flow rate of the heat transfer medium HM sent from the heat source device 21 (from the current setting), thereby lowering the thermal output of the heat pump (i.e., the hot water temperature). As a result, the temperature and humidity of the cold air coming out of the fan of the refrigerant evaporator 211 increase, causing the temperature, humidity, and discomfort index of the work area WA to rise.

[0093] <4-3-2-2> Lowering the frequency of operation The operating condition generation module 32 generates new operating conditions 53B, which are operating conditions that lower the operating frequency information 522. For example, for load equipment LE that generates hot water demand, the tank water level setting for starting heating operation is changed to a lower level than usual. This reduces the operating frequency of the refrigerant compressor 213 per unit time (the operating frequency information 522 is lowered). As the operating frequency of the heat source device 21 decreases, the temperature, humidity, and discomfort index of the work area WA increase. Also, for load equipment LE that generates heat demand, the water return temperature for starting heating operation is changed to a lower level than usual. This reduces the operating frequency of the refrigerant compressor 213 per unit time.

[0094] <4-3-2-3> Lowering of the number of operating units The operating condition generation module 32 generates a new operating condition 53B which lowers the operating unit number information 523. For example, the rotational speed (load factor) of the refrigerant compressor 213 of the first heat source unit 21 remains unchanged, while the second heat source unit 21 is stopped. By reducing the number of operating heat source units 21, the temperature, humidity, and discomfort index of the work area WA increase.

[0095] Furthermore, a new operating condition 53 that upgrades any of the operating information 52 includes returning an operating condition 53 that has been lowered from the standard back to the standard operating condition 53. Similarly, a new operating condition 53 that upgrades any of the operating information 52 back to the standard operating condition 53 includes returning an operating condition 53 that has been upgraded from the standard back to the standard operating condition 53. In other words, a new operating condition 5B3 that upgrades any of the operating information 52, or a new operating condition 53C that upgrades any of the operating information 52 back to the standard, includes returning the rotational speed of the refrigerant compressor 213 to the standard value, returning the conditions for starting the heating operation (tank water level and return temperature) to the standard value, and setting the number of operating units to the result of the standard increase / decrease control, if the immediately preceding operating condition differs from the specified value (standard value).

[0096] When the heat source device 21 is operating under operating condition 53C, which is a lower operating condition than any of the operating information 52, the amount of hot water and heat supplied from the heat source device 21 will be suppressed. Therefore, if a sudden increase in the hot water demand or heat demand of the load equipment LE is detected, the operating level may be temporarily increased while switching the heat source air for the evaporator 211. Specifically, the heat source air for the evaporator 211 is switched from indoor air in the work area WA to hotter outdoor air. For example, an intake hood and an exhaust hood are installed on the evaporator 211, and a first supply duct and a first exhaust duct of indoor air are connected to the intake hood, while a second supply duct and a second exhaust duct of outdoor air are connected to the exhaust hood. When indoor air is supplied to the evaporator 211, the second supply duct and the second exhaust duct are closed, while the first supply duct and the first exhaust duct are opened. Conversely, when supplying outdoor air to the evaporator 211, the first supply duct and the first exhaust duct are closed, while the second supply duct and the second exhaust duct are opened. By utilizing outdoor air, it becomes possible to temporarily increase the amount of hot water supplied or the amount of heat supplied.

[0097] <4-4> Operating Condition Change Module The operating condition change module 33 transmits the new operating conditions 53 generated by the operating condition generation module 32 to the controller 61 (heat source device 21) via the communication network 8, causing the controller to change the operating conditions 53. Upon receiving the new operating conditions 53, the controller 61 updates the operating conditions of the heat source device 21 with the received new operating conditions 53 and operates the heat source device 21 according to the revised operating conditions 53.

[0098] <4-5> UI Provision Module As shown in Figure 5, the UI providing module 34 provides a user interface (UI) for displaying information such as the operational performance of the driver assistance system 1 on the user terminal 40. The user interface is a means of accessing the driver assistance system 1. The user interface mainly includes a function to display the UI screen on the user terminal 40 and a function to receive operation input for various functions provided via the UI screen.

[0099] The UI providing module 34 displays various types of information on the user terminal 40, such as environmental information 51 (latest information on ambient temperature 511, ambient humidity 512, and discomfort index 513 of the work area WA), operating information 52 for the heat source device 21, and operating conditions 53 for the heat source device 21.

[0100] <4-6> Database Database 36 stores standard values ​​for operating conditions 53, information on load equipment LE, and equipment flow diagrams that depict the overall or partial configuration of the heat supply equipment 2 and the factory 4.

[0101] [5] Example of a heat supply system configuration The configuration of the heat supply equipment 2 according to this embodiment for supplying the heat transfer medium HM to the load equipment LE can take various forms and is not particularly limited. A typical example of the configuration of the heat supply equipment 2 will be described below.

[0102] <5-1> First Configuration Example Figure 9 is a schematic diagram showing a first configuration example of the heat supply equipment 2 according to the embodiment. In Figure 9, the load equipment LE indirectly uses heated water (heat transfer water HM) (i.e., provides thermal output). In Figure 9, the heating of the heat transfer medium HM by the heat source device 21 takes place along the path through which the heat transfer medium HM is sent to the load equipment LE.

[0103] The heat supply equipment 2 includes a heat source device 21 that heats the water using an electric heat pump, a water tank 22, and an auxiliary heat source device 24 that heats the water using a combustion or electric boiler. The water line 23 includes a distribution line 231 and a return line 232. The heat supply equipment 2 heats the water used by the load equipment LE within the business premises as the heat transfer water HM.

[0104] The water tank 22 stores water, which is the heat transfer medium HM, as stored water. The water tank 22 is, for example, an open-type tank. The water tank 22 is equipped with a water level sensor 221. When the water level sensor 221 detects a decrease in the water level in the water tank 22, replenishment water is supplied to the water tank 22 through the replenishment water line 233. The water tank 22 may also be equipped with an environmental sensor 5. In this case, the environmental sensor 5 is a temperature sensor that detects the temperature of the water stored in the water tank 22.

[0105] The water distribution line 231 and the water return line 232 connect the water tank 22 and the load equipment LE, respectively. In Figure 9, the water distribution line 23, along with the water return line 231 and the water return line 232, forms a circulation line for a hot water loop system. A water supply pump 25 is provided in the water distribution line 231. The water distribution line 231 is the supply pipe that provides water from the water tank 22 to the load equipment LE. The water stored in the water tank 22 is supplied to the load equipment LE via the water distribution line 231. In the load equipment LE, heat is removed from the water through heat exchange, and the water temperature decreases. The water return line 232 is the return pipe that returns water from the load equipment LE to the water tank 22. The water that has been used in the load equipment LE and whose temperature has decreased flows to the water return line 232.

[0106] The heat source device 21 consists of an air-source heat pump as shown in Figure 2. In the first configuration example in Figure 9, the heat source device 21 further includes a sub-heat exchanger 216, a sub-circulation pump 217, and a sub-circulation line 218.

[0107] The sub-circulation line 218 connects the sub-heat exchanger 216 to the refrigerant condenser 212 of the heat source device 21. Intermediate heat transfer medium HM2 flows through the sub-circulation line 218. The intermediate heat transfer medium HM2 circulating in the sub-circulation line 218 may be water. A sub-circulation pump 217 is provided in the sub-circulation line 218. The sub-circulation pump 217 circulates the heat transfer medium HM flowing through the sub-circulation line 218.

[0108] The heat source device 21 absorbs heat from the air in the work area WA using the refrigerant evaporator 211. The heat source device 21 then releases (heats) the absorbed heat to the intermediate heat transfer medium HM2 circulating in the sub-circulation line 218 using the refrigerant condenser 212. The heat source device 21 also heats the water flowing through the return water line 232.

[0109] The sub-heat exchanger 216 performs heat exchange between the heat transfer medium HM flowing through the water supply line 23 and the intermediate heat transfer medium HM2 flowing through the sub-circulation line 218, thereby heating the heat transfer medium HM. In the first configuration example shown in Figure 9, the sub-heat exchanger 216 is located in the return water line 232 from the load equipment LE, and heats the water used as the heat transfer medium HM with the heat from the intermediate heat transfer medium HM2. The heated water is then sent to the water supply tank 22 via the return water line 232.

[0110] Environmental sensors 5 may be installed in the water supply line 23. Environmental sensors 5 are temperature sensors and may be installed in one or more locations in the water supply line 23. The installation locations of environmental sensors 5 include, for example, the water distribution line 231 between the water supply tank 22 and the load equipment LE, the upstream location of the sub-heat exchanger 216 in the return water line 232, and the downstream location of the sub-heat exchanger 216 in the return water line 232. In Figure 9, environmental sensors 5 are installed upstream of the location where the sub-heat exchanger 216 is located in the return water line 232. Environmental sensors 5 are temperature sensors that detect the return temperature of the water. In Figure 9, environmental sensors 5 are installed downstream of the location where the sub-heat exchanger 216 is located in the return water line 232. Environmental sensors 5 are temperature sensors that detect the temperature of the water heated by the heat source device 21 (hot water outlet temperature).

[0111] The auxiliary heat source device 24 heats the water in the water tank 22. The auxiliary heat source device 24 includes a group of steam boilers consisting of one or more steam boilers. The auxiliary heat source device 24 supplies steam to the steam line 234. The steam line 234 is equipped with a steam heater 241 and a steam supply valve 242.

[0112] The steam line 234 supplies steam ST from the steam boiler to the steam heater 241. After heat exchange in the steam heater 241, the steam ST is discharged from the steam heater 241 through the steam line 234. The steam heater 241 is installed inside the water tank 22. The steam heater 241 performs heat exchange between the water in the water tank 22 and the steam ST flowing through the steam line 234, heating the stored water. The steam supply valve 242 controls the flow state of the steam ST flowing through the steam line 234. Preferably, the steam supply valve 242 is a proportional control valve with an adjustable opening.

[0113] In the first configuration example, the heat source device 21 heats the water via a sub-heat exchanger 216 located in the return water line 232. The auxiliary heat source device 24 heats the water via a steam heater 241 located in the water tank 22. The heat source device 21 functions as a base load machine for the thermal demand of the load equipment LE, and the auxiliary heat source device 24 functions as a peak load machine. In other words, when the thermal demand of the load equipment LE exceeds the heat supply capacity of the heat source device 21, the auxiliary heat source device 24 heats the heat transfer medium HW in proportion to the excess thermal demand.

[0114] The heat source device 21 may also be configured such that the return water line 232 is directly connected to the refrigerant condenser 212. In this case, the heat source device 21 dissipates heat (heats the water) from the refrigerant circulating in the refrigerant circulation line 215 to the heat transfer medium HM (water) circulating in the return water line 232 via the refrigerant condenser 212. In this case, the sub-heat exchanger 216, sub-circulation pump 217, and sub-circulation line 218 can be omitted.

[0115] Furthermore, if the heat supply capacity of the heat source device 21 can meet the entire thermal demand of the load equipment LE, then it is not necessary to provide the auxiliary heat source device 24.

[0116] <5-2> Second Configuration Example Figure 10 is a schematic diagram showing a second configuration example of the heat supply equipment 2 according to the embodiment. In Figure 10, the load equipment LE indirectly uses heated water (heat transfer water HM) (i.e., provides thermal output). The heating of the heat transfer medium HM by the heat source device 21 in Figure 10 differs from the first configuration example in that it is performed outside the path through which the heat transfer medium HM is sent to the load equipment LE. Note that in the second configuration example, explanations of configurations similar to those in the first configuration example may be omitted.

[0117] As shown in Figure 10, the heat source device 21 is not located in the return water line 232 of the heat supply equipment 2 in the second configuration example. The heat supply equipment 2 of the embodiment includes a circulation line 235 that circulates the water stored in the water tank 22. In the second configuration example, the heat source device 21 heats the water flowing through the circulation line 235 that circulates the water stored in the water tank 22. The auxiliary heat source device 24 heats the water stored in the water tank 22.

[0118] The circulation line 235 is connected at one end to the water tank 22 and is a line for circulating the water in the water tank 22. A sub-heat exchanger 216 is located in the circulation line 235. A circulation pump 26 is provided in the circulation line 235.

[0119] The sub-heat exchanger 216 performs heat exchange between the water flowing through the circulation line 235 and the intermediate heat transfer medium HM2 flowing through the sub-circulation line 218. The heat source device 21 heats the water (heat transfer medium HM) flowing through the circulation line 235 with the temperature of the intermediate heat transfer medium HM2.

[0120] Environmental sensors 5 are provided in the return water line 232 and the circulation line 235. These environmental sensors 5 are temperature sensors that detect the return temperature of the water (heat transfer medium HM).

[0121] As described above, in the second configuration example, the heat source device 21 heats the water via a sub-heat exchanger 216 located in the circulation line 235. The circulation pump 26 sends the heated water from the circulation line 235 into the water tank 22, and sends the stored water in the water tank 22 to the sub-heat exchanger 216 in the circulation line 235. The water stored in the water tank 22 is heated by the circulation of the water.

[0122] <5-3> Third Configuration Example Figure 11 is a schematic diagram showing a third configuration example of the heat supply equipment 2 according to the embodiment. In Figure 11, the load equipment LE directly uses heated water (i.e., hot water output). In Figure 11, heating of the heat transfer medium HM by the heat source device 21 takes place on the path through which the heat transfer medium HM is sent to the load equipment LE. Note that in the third configuration example, the same configuration as in the first configuration example may be omitted from the explanation.

[0123] In the first and second configuration examples, a return water line 232 is provided to return water from the load equipment LE to the water tank 22. However, in the heat supply equipment 2 according to the third configuration example, the return water line 232 is not provided. In other words, in this third configuration example, the load equipment LE directly uses the heated water as, for example, washing water (i.e., hot water output). Since the water is consumed in the load equipment LE, it is not returned to the water tank 22.

[0124] As shown in Figure 11, in the heat supply equipment 2 according to the third configuration example, the water supply line 236 is connected to the water tank 22. A water supply pump 27 is installed in the water supply line 236.

[0125] The heat source device 21 heats the water (heat transfer medium HM) flowing through the water supply line 236. That is, the sub-heat exchanger 216 of the heat source device 21 is located in the water supply line 236. The auxiliary heat source device 24 heats the water in the water supply tank 22. Here, the configuration in which the heat source device 21 heats the water flowing through the water supply line 236 and the configuration in which the auxiliary heat source device 24 heats the water in the hot water tank are the same as in the first configuration example described above, so an explanation is omitted.

[0126] <5-4> Fourth Configuration Example Figure 12 is a schematic diagram showing a fourth configuration example of the heat supply equipment 2 according to the embodiment. In Figure 12, the load equipment LE directly uses heated water (i.e., hot water output). In Figure 12, heating of the heat transfer medium HM by the heat source device 21 is performed outside the path through which the heat transfer medium HM is sent to the load equipment LE. Note that in the fourth configuration example, explanations of configurations similar to those in the second configuration example may be omitted.

[0127] In the fourth configuration example, similar to the third configuration example, the load equipment LE directly uses the heated water (i.e., hot water output). On the other hand, in the fourth configuration example, similar to the second configuration example, the heat source device 21 heats the water in the circulation line 235 that circulates the water stored in the water tank 22. Note that in the fourth configuration example, explanations of configurations similar to those in the second configuration example may be omitted.

[0128] As shown in Figure 12, the sub-heat exchanger 216 of the heat source device 21 is not located in the water supply line 236 of the heat supply equipment 2 of the embodiment. In the fourth configuration example, the heat source device 21 heats the water flowing through the circulation line 235. That is, the sub-heat exchanger 216 of the heat source device 21 is located in the circulation line 235. The auxiliary heat source device 24 heats the water stored in the water tank 22. Here, the configuration in which the heat source device 21 heats the water (heat transfer medium HM) flowing through the circulation line 235 and the configuration in which the auxiliary heat source device 24 heats the water in the hot water tank are the same as in the second configuration example, so an explanation is omitted.

[0129] [6] Driving assistance methods and driving assistance application programs Figure 13 is a flowchart illustrating a driving assistance method according to the embodiment. Figure 13 is also a processing flowchart that the driving assistance application program according to the embodiment causes the computer to execute, and is also an operation flowchart of the driving assistance system 1 according to the embodiment.

[0130] The operation support method according to this embodiment is an operation support method for a heat supply equipment 2 that includes an air-source heat pump with a refrigerant evaporator 211 installed in the work area WA, and comprises at least one heat source device 21 that heats the heat transfer medium HM supplied to the load equipment LE.

[0131] First, the heat supply equipment 2 is started (step S10). The controller 61 of the heat supply equipment 2 operates the heat source device 21 according to the operating conditions 53.

[0132] While the heat supply equipment 2 is in operation, environmental information 51 is generated from each environmental sensor 5 that makes up the sensor group, and operation information 52 of the heat source device 21 is generated by the controller 61 that controls the operation of the heat source device 21. The environmental information 51 and operation information 52 are acquired by the information processing device 6 (step S11). The acquired environmental information 51 and operation information 52 are stored in the information storage platform 35.

[0133] The operation support method according to the embodiment includes the computer 10 generating new operating conditions 53 for the heat source device 21 using time-series environmental information 51 acquired from the work area WA and time-series operation information 52 acquired from the heat source device 21 (step S12). The operation support application program 100 causes the computer 10 to operate as an operating condition generation module 32 and execute the process of generating new operating conditions 53 for the heat source device 21.

[0134] The operation support method according to this embodiment includes transmitting new operating conditions 53 to the heat source device 21 via the communication network 8 and causing it to change the operating conditions 53 (step S13). The operation support application program 100 operates the computer 10 as an operating condition change module 33, transmitting the new operating conditions 53 to the controller 61 of the heat source device 21 and causing it to change the operating conditions 53. As a result, the controller 61 controls the operation of the heat source device 21 according to the new operating conditions 53.

[0135] [Second Embodiment] Figure 14 is a schematic diagram showing the heat supply equipment 2 and load equipment LE according to the second embodiment. The second embodiment shows an example in which, in addition to the first embodiment, air conditioning equipment 9 is installed in the work area WA. In the second embodiment, the description of configurations that are the same as those in the first embodiment may be omitted.

[0136] In the second embodiment, the operation support system 1 comprises a heat supply system 2 and an air conditioning system 9 installed in a facility including a work area WA, such as a factory 4. Similar to the first embodiment, the heat supply system 2 has an air source heat pump with a refrigerant evaporator 211 installed in the work area WA, and includes at least one heat source device 21 that heats the heat transfer medium HM supplied to the load equipment LE. The air conditioning system 9 includes at least one air conditioner 91 installed in the work area WA. The computer 10 on which the operation support application program 100 operates can send and receive information with these heat supply system 2 and air conditioning system 9 via a communication network 8.

[0137] The air conditioning system 9 adjusts the temperature and humidity inside the factory building through the operation of the air conditioner 91. The air conditioner 91 has an air-source heat pump and adjusts the temperature and humidity of the air in the installation environment. The air conditioner 91 installed in the work area WA adjusts the ambient temperature, ambient humidity, and discomfort index of the work area WA.

[0138] Therefore, in the second embodiment, the ambient temperature, ambient humidity, and discomfort index of the work area WA are adjusted by the heat absorption operation (cooling effect) of the refrigerant evaporator 211 of the heat source device 21 and the operation of the air conditioner 91.

[0139] The driver assistance system 1 comprises a sensor group consisting of one or more environmental sensors 5, a controller 61 that controls the heat source device 21 according to operating conditions 53, a second controller 66 that controls the air conditioner 91 according to cooling temperature conditions, and an information processing device 6 consisting of a computer 10. The information processing device 6 can acquire environmental information 51 detected by the environmental sensors 5 and operating information 52 generated by the controller 61 via a communication network 8, and can acquire operating information 55 generated by the second controller 66 via a communication network 8.

[0140] Figure 15 is a diagram illustrating various types of information according to the second embodiment. In the second embodiment, time-series environmental information 51 acquired from the work area WA, time-series operational information 52 acquired from the heat source device 21, and time-series operating information 55 acquired from the air conditioner 91 are stored in the information storage platform 35. The environmental information 51 and operational information 52 are the same as in the first embodiment described above.

[0141] The operating information 55 is information indicating the operating status of the air conditioner 91. The operating information 55 includes information on the operating load ratio 551 of the air conditioner 91. The operating load ratio 551 is the ratio of the current value to the maximum value of the load (rotational speed) of the refrigerant compressor of the air conditioner 91. If the air conditioning system 9 has multiple air conditioners 91 in the work area WA, the operating load ratio 551 may be a representative value (mean, median, mode, etc.) of the operating load ratio 551 of each air conditioner 91.

[0142] In the second embodiment, the operating condition generation module 32 uses operating information 55 to generate new operating conditions 53 for the heat source device 21. Specifically, the operating condition generation module 32 generates new operating conditions 53 for the heat source device 21 using time-series environmental information 51 acquired from the work area WA, time-series operating information 52 acquired from the heat source device 21, and time-series operating information 55 acquired from the air conditioner 91. On the other hand, the operation control of the air conditioner 91 by the second controller 66 is performed independently of the operation of the heat source device 21, according to the cooling temperature conditions.

[0143] Figure 16 is a diagram illustrating the process for generating operating conditions according to the second embodiment. In the second embodiment, if a predetermined time has elapsed with the operating load ratio 551 exceeding a specified value (upper threshold 543), the newly generated operating conditions 53 include operating conditions 53 that upgrade any of the operating information 52. In other words, if a predetermined time has elapsed with the operating load ratio 551 exceeding a specified value, the operating condition generation module 32 newly generates operating conditions 53B that upgrade any of the operating information 52.

[0144] If a predetermined time has elapsed while the operating load ratio 551 is below a specified value, the newly generated operating conditions 53 include operating conditions 53 that lower any of the operating information 52. In other words, if a predetermined time has elapsed while the operating load ratio 551 is below a specified value (lower threshold 544), the operating condition generation module 32 generates new operating conditions 53C that lower any of the operating information 52.

[0145] If the operating load factor 551 is within the reference range 54 between the upper threshold 543 and the lower threshold 544, the current operating conditions 53A are maintained. The operating conditions generation module 32 maintains the current operating conditions 53A if the numerical value of the environmental information 51 is within the reference range 54.

[0146] The upper threshold 543 of the operating load factor 551 is not particularly limited, but for example, it is 90%. The lower threshold 544 of the operating load factor 551 is not particularly limited, but for example, it is 0%. The predetermined time is not particularly limited, but for example, it is 10 minutes.

[0147] For example, let's assume that the set temperature of the air conditioner 91 is 28°C during the summer. If the air conditioner 91 is operating at a high load rate to lower the indoor temperature of the work area WA to 28°C, and the average load rate of multiple air conditioners 91 exceeds the upper threshold 543 (e.g., 90%) for a predetermined time (e.g., 10 minutes), the indoor environment is likely to continue to deteriorate and the discomfort index will exceed 70%. Therefore, the duration of the high load rate state is used as a trigger to generate operating condition 53B, which increases the cooling effect of the heat source device 21 and adjusts the discomfort index to 60-70%.

[0148] As the cooling effect of the heat source device 21 is enhanced, the indoor temperature decreases. As the indoor temperature decreases, the cooling capacity of the air conditioner 91, i.e., the operating load rate, decreases, and the amount of heat absorbed by the heat source device 21 and the air conditioner 91 and the amount of heat input to the work area WA are balanced at an operating load rate that maintains an indoor temperature of 28°C.

[0149] Furthermore, if the cooling effect of the heat source device 21 is significant and the room temperature falls below 28°C solely through the cooling effect of the heat source device 21, the air conditioner 91 will switch to standby mode (operating load factor 551 is 0%). If a predetermined time elapses in this state, operating condition 53C is generated, and the cooling effect of the heat source device 21 is reduced.

[0150] In the second embodiment, the generation of new operating conditions 53 based on the operating load factor 551 and the generation of new operating conditions 53 based on the environmental information 51 shown in Figure 7 may be performed using an AND condition or an OR condition. In the case of an AND condition, the operating condition generation module 32 generates an operating condition 53B that upgrades one of the operating information 52 if a predetermined time has elapsed with the operating load factor 551 exceeding a specified value and the environmental information 51 exceeds the upper limit 541 of the reference range 54. In the case of an OR condition, the operating condition generation module 32 generates an operating condition 53B that upgrades one of the operating information 52 if at least one of the following conditions is met: the operating load factor 551 has elapsed with the specified value for a predetermined time and the environmental information 51 exceeds the upper limit 541 of the reference range 54.

[0151] [7] Effects As described above, in the first embodiment, the operation support application program 100 is an operation support application program that operates on a computer 10 capable of sending and receiving information via a communication network 8 with a heat supply system 2 which has an air source heat pump with a refrigerant evaporator 211 installed in the work area WA and includes at least one heat source device 21 that heats the heat transfer medium HM supplied to the load equipment LE. The computer 10 is instructed to generate new operating conditions 53 for the heat source device 21 using time-series environmental information 51 acquired from the work area WA and time-series operation information 52 acquired from the heat source device 21, and to transmit the new operating conditions 53 to the heat source device 21 to cause it to change the operating conditions 53.

[0152] This configuration makes it possible to understand changes in the work environment from time-series environmental information 51 acquired from the work area WA. In addition, it becomes possible to review the operating conditions 53 of the heat source device 21 from time-series operational information 52 acquired from the heat source device 21. When the operating conditions 53 are changed by the operation support application program 100, the heat source device 21 operates under the new operating conditions 53. The temperature and humidity of the work area WA are adjusted by the heat absorbed by the refrigerant evaporator 211 under the new operating conditions 53. As a result, the comfort of the work environment is improved.

[0153] In the first embodiment, the environmental information 51 includes one or more of the following information: ambient temperature information 511, ambient humidity information 512, and discomfort index information 513 of the work area WA. The operation information 52 includes one or more of the following information: heat output information 521, operating frequency information 522, and number of operating units information 523 of the heat source device 21. If the value of the environmental information 51 exceeds the upper limit 541 of the preset reference range 54 for the work area WA, the generated new operation conditions 53 include an operation condition 53 that increases any of the operation information 52. In this configuration, if any of the ambient temperature, ambient humidity, or discomfort index exceeds the upper limit, a new operation condition 53 is set that increases any of the heat output, operating frequency, or number of operating units of the heat source device 21. By increasing the rotation speed of the refrigerant compressor 213 and raising the heat output (hot water temperature) of the heat pump, the temperature and humidity of the cold air coming out of the fan of the refrigerant evaporator 211 decreases, thus lowering the ambient temperature and humidity. Increasing the operating frequency of the heat pumps increases the frequency with which the refrigerant evaporator 211 absorbs heat from the ambient air, thereby lowering or leveling (reducing fluctuations) the ambient temperature and humidity. Increasing the number of operating heat pumps increases the amount of heat removed from the ambient air, lowering the ambient temperature and humidity. Therefore, the comfort level of the work area WA can be effectively improved.

[0154] In the first embodiment, if the value of the environmental information 51 falls below the lower limit 542 of the reference range 54, the generated new operating conditions 53 include operating conditions 53 that reduce any of the operating information 52. In this configuration, if the ambient temperature and humidity drop too low as a result of continuing operating conditions 53 that increase the cooling effect of the heat pump, new operating conditions 53 that reduce (or return to the original) the cooling effect of the heat pump can be set. This makes it possible to maintain comfort in the work area WA.

[0155] In the first embodiment, the operation support system 1 is an operation support system for a heat supply equipment 2 which has an air source heat pump with a refrigerant evaporator 211 installed in the work area WA and includes at least one heat source device 21 that heats the heat transfer medium HM supplied to the load equipment LE, and includes a sensor group consisting of one or more environmental sensors 5 installed in the heat supply equipment 2, a controller 61 that controls the heat source device 21 according to required operating conditions 53, a communication network 8 that transmits information, and environmental information 51 detected by the environmental sensors 5 and operating information 52 generated by the controller 61, The system includes an information processing device 6 configured to be accessible via a communication network 8, the information processing device 6 comprising: an information storage platform 35 that stores acquired environmental information 51 and operational information 52; an operational condition generation module 32 that generates new operational conditions 53 for the heat source device 21 using the environmental information 51 and operational information 52 stored in the information storage platform 35; and an operational condition change module 33 that transmits the new operational conditions 53 generated by the operational condition generation module 32 to the controller 61 via the communication network 8, causing the controller to change the operational conditions 53.

[0156] With this configuration, time-series environmental information 51 acquired from the work area WA is stored in the information storage platform 35, enabling the operating condition generation module 32 to grasp changes in the work environment. Furthermore, time-series operational information 52 acquired from the heat source device 21 is stored in the information storage platform 35, enabling the operating condition generation module 32 to revise the operating conditions 53 of the heat source device 21. When the operating conditions 53 are changed by the operation of the operating condition change module 33, the heat source device 21 operates under the new operating conditions 53. The temperature and humidity of the work area WA are adjusted by the heat absorbed by the refrigerant evaporator 211 under the new operating conditions 53. As a result, the comfort of the work environment is improved.

[0157] In the first embodiment, the operation support method is an operation support method for a heat supply equipment 2 comprising an air-source heat pump with a refrigerant evaporator 211 installed in a work area WA, and at least one heat source device 21 that heats a heat transfer medium HM supplied to a load equipment LE, and includes generating new operating conditions 53 for the heat source device 21 using time-series environmental information 51 acquired from the work area WA and time-series operation information 52 acquired from the heat source device 21 by a computer 10, and transmitting the new operating conditions 53 to the heat source device 21 via a communication network 8 to cause the operating conditions 53 to be changed.

[0158] This configuration makes it possible to understand changes in the work environment from time-series environmental information 51 acquired from the work area WA. In addition, it becomes possible to review the operating conditions 53 of the heat source device 21 from time-series operational information 52 acquired from the heat source device 21. When the operating conditions 53 are changed by implementing the operation support method, the heat source device 21 operates under the new operating conditions 53. The temperature and humidity of the work area WA are adjusted by the heat absorbed by the refrigerant evaporator 211 under the new operating conditions 53. As a result, the comfort of the work environment is improved.

[0159] In the second embodiment, the operation support application program 100 is an operation support application program that operates on a computer 10 capable of sending and receiving information via a communication network with a heat supply system 2 comprising an air source heat pump with a refrigerant evaporator 211 installed in the work area WA and at least one heat source device 21 that heats a heat transfer medium HM supplied to the load equipment LE, and an air conditioning system 9 comprising at least one air conditioner 91 installed in the work area WA. The computer 10 is instructed to generate new operating conditions 53 for the heat source device 21 using time-series environmental information 51 acquired from the work area WA, time-series operation information 52 acquired from the heat source device 21, and time-series operation information 55 acquired from the air conditioner 91, and to transmit the new operating conditions 53 to the heat source device 21 and cause it to change the operating conditions 53.

[0160] With this configuration, it becomes possible to understand changes in the work environment from time-series environmental information 51 acquired from the work area WA. It becomes possible to understand the operating load status of the air conditioner 91 from time-series operation information 55 acquired from the air conditioner 91. In addition, it becomes possible to review the operating conditions 53 of the heat source device 21 from time-series operation information 52 acquired from the heat source device 21. When the operating conditions 53 are changed by the operation support application program 100, the heat source device 21 operates under the new operating conditions 53. The temperature and humidity of the work area WA are adjusted by the heat absorption of the refrigerant evaporator 211 under the new operating conditions 53. As a result, even if the temperature and humidity of the work area WA cannot be properly maintained by the air conditioner 91 alone, the temperature and humidity can be further adjusted by the operation of the heat source device 21, thereby improving the comfort of the work environment.

[0161] In the second embodiment, the operation information 52 includes one or more of the following information: heat output information 521 of the heat source device 21, operating frequency information 522, and operating number information 523. The operation information 55 includes information on the operating load ratio 551 of the air conditioner 91. If a predetermined time has elapsed with the operating load ratio 551 exceeding a specified value, the generated new operating conditions 53 include operating conditions 53 that increase any of the operating information 52. In this configuration, if comfort cannot be maintained even with an increased operating load ratio 551 of the air conditioner 91, new operating conditions 53 are set that increase any of the heat output, operating frequency, and operating number of the heat source device 21. By increasing any of the heat output, operating frequency, and operating number, the ambient temperature and humidity decrease. Therefore, the comfort of the work area WA can be effectively improved.
