Embodiment 1.
Fig. 1 is a configuration diagram of a system to which a ventilation system according to embodiment 1 of the present invention is applied.
In fig. 1, a central monitoring apparatus 1 is installed so as to be able to monitor a building or the like in which a space to be ventilated is located as a whole. The central monitoring apparatus 1 is provided to be able to monitor the operating state of equipment of a building, for example. The central monitoring apparatus 1 is provided to be able to monitor abnormality of equipment of a building, for example. The central monitoring apparatus 1 is provided to be able to monitor the presence or absence of a person in a space to be ventilated, for example. The central monitoring apparatus 1 is provided to monitor whether or not the space to be ventilated is used, for example.
The human detection sensor 2 is provided in the ventilation target space. The human body sensor 2 is installed on, for example, a ceiling of a room forming a space to be ventilated. The human detection sensor 2 is provided to be able to detect a human present in the ventilation target space.
The ventilation system 3 is provided to be able to perform ventilation of the space to be ventilated at all times. The ventilation system 3 includes, for example, an indoor unit 4, an outdoor unit 5, and a control device 6.
The indoor unit 4 is installed on a ceiling of a room forming a space to be ventilated, for example. The indoor unit 4 includes a heat exchanger 7, an intake air blower 8, an exhaust air blower 9, and an evaporator 10.
The heat exchanger 7 is provided in an intake air passage between the outside and the space to be ventilated, and in an adjacent portion of an exhaust air passage between the space to be ventilated and the outside. The heat exchanger 7 is provided, for example, in a portion adjacent to an intake air passage formed by the 1 st duct 11 and the 2 nd duct 12 and an exhaust air passage formed by the 3 rd duct 13 and the 4 th duct 14. The heat exchanger 7 is provided so as to be able to exchange heat between air flowing in the intake air passage and air flowing in the exhaust air passage.
The intake air blower 8 is provided in the intake air duct on the side of the space to be ventilated from the heat exchanger 7. The intake blower 8 is provided so as to be able to generate a flow of air from the outside toward the space to be ventilated inside the intake air duct.
The exhaust blower 9 is provided in the exhaust duct on the side of the space to be ventilated with respect to the heat exchanger 7. The intake blower 8 is provided so as to be able to generate a flow of air from the space to be ventilated to the outside in the exhaust duct.
The evaporator 10 is provided in the intake air duct on the ventilation target space side of the intake air blower 8. The evaporator 10 is provided to be able to perform heat exchange between refrigerant and air.
The outdoor unit 5 is installed, for example, on a roof of a building in which a room forming a space to be ventilated is located. The outdoor unit 5 includes a compressor 15, a condenser 16, and an expansion valve 17.
The compressor 15 is provided to receive the input of the refrigerant from the evaporator 10 via the 1 st pipe 18. The compressor 15 is provided to be capable of compressing refrigerant.
The condenser 16 is provided to receive the refrigerant input from the compressor through a 2 nd pipe 19. The condenser 16 is provided to be able to perform heat exchange between the refrigerant and outside air.
The expansion valve 17 is provided to receive the refrigerant input from the condenser 16 via the 3 rd pipe 20. The expansion valve 17 is provided to be able to decompress the refrigerant. The expansion valve 17 is provided to be able to output the decompressed refrigerant to the evaporator 10 via the 4 th pipe 21.
The control device 6 is arranged to be able to control the ventilation system 3 as a whole. The control device 6 is provided to be able to switch the operation mode of the ventilation system 3, for example.
When the operation mode of the ventilation system 3 is, for example, the air blowing mode, the controller 6 stops the operation of the compressor 15. When the operation mode of the ventilation system 3 is, for example, the cooling mode, the controller 6 operates the compressor 15 to lower the temperature of the space to be ventilated. When the operation mode of the ventilation system 3 is, for example, the heating mode, the controller 6 operates the compressor 15 to increase the temperature of the space to be ventilated. When the operation mode of the ventilation system 3 is, for example, the automatic mode, the controller 6 operates the compressor 15 to adjust the temperature of the space to be ventilated, based on its own judgment.
When a condition set in advance as a condition that no person is present in the space to be ventilated is satisfied when the operation mode of the ventilation system 3 is any one of the cooling mode, the heating mode, and the automatic mode, the controller 6 switches the operation mode of the ventilation system 3 to the air blowing mode. At this time, the controller 6 stops the operation of the compressor 15.
For example, when the human detection sensor 2 does not detect a human, the control device 6 switches the operation mode of the ventilation system 3 to the air blowing mode. For example, when receiving information corresponding to the absence of a person from the central monitoring apparatus 1, the control apparatus 6 switches the operation mode of the ventilation system 3 to the air blowing mode. For example, when a predetermined time has elapsed, controller 6 switches the operation mode of ventilation system 3 to the air blowing mode.
Next, an outline of the operation of the control device 6 will be described with reference to fig. 2.
Fig. 2 is a flowchart for explaining an outline of an operation of the control device of the ventilation system in embodiment 1 of the present invention.
In step S1, the control device 6 determines whether or not a condition set in advance as a condition that no person is present in the space to be ventilated is satisfied.
When it is determined in step S1 that the condition set in advance as the condition that no person is present in the space to be ventilated is not satisfied, the control device 6 performs the operation of step S2. In step S2, the control device 6 maintains the operation mode of the ventilation system 3 in the current operation mode. Then, the control device 6 performs the operation of step S1.
When it is determined in step S1 that the condition set in advance as the condition that no person is present in the space to be ventilated is satisfied, the control device 6 performs the operation of step S3. In step S3, control device 6 switches the operation mode of ventilation system 3 to the air blowing mode. Then, the control device 6 performs the operation of step S4.
In step S4, the control device 6 determines whether or not the human sensor 2 detects a human. If the human sensor 2 does not detect a human in step S4, the control device 6 performs the operation of step S1. If the human sensor 2 detects a human in step S4, the control device 6 performs the operation of step S5.
In step S5, control device 6 returns the operation mode of ventilation system 3 to the operation mode before switching to the air blowing mode. Then, the control device 6 performs the operation of step S1.
According to embodiment 1 described above, when a condition set in advance as a condition that no person is present in the space to be ventilated is satisfied, the operation of the compressor 15 is stopped. Therefore, the compressor 15 can be prevented from operating even when a person is not present. As a result, the power consumption of the ventilation system 3 can be suppressed. By suppressing the power consumption of the ventilation system 3, the electricity fee can be suppressed.
For example, if the human detection sensor 2 does not detect a human, the control device 6 switches the operation mode of the ventilation system 3 to the air blowing mode. Therefore, it is possible to more appropriately suppress the compressor 15 from operating even when a person is not present.
For example, when receiving information corresponding to absence of a person from the central monitoring apparatus 1, the control apparatus 6 switches the operation mode of the ventilation system 3 to the air blowing mode. Therefore, it is possible to more appropriately suppress the compressor 15 from operating even when a person is not present.
For example, when a preset time comes, controller 6 switches the operation mode of ventilation system 3 to the air blowing mode. Therefore, it is possible to more appropriately suppress the compressor 15 from operating even when a person is not present.
For example, when the operation mode of ventilation system 3 is switched to the air blowing mode at the time of arrival of time 1 in the evening, the operation mode of ventilation system 3 may be returned to the operation mode before the switching to the air blowing mode at the time of arrival of time 2 in the next morning. In this case, the space to be ventilated can be kept in a comfortable state until the person reaches the space to be ventilated.
When the human detection sensor 2 detects a human, the control device 6 returns the operation mode of the ventilation system 3 to the operation mode before the switching to the air blowing mode. Therefore, an environment comfortable to humans can be maintained.
The control device 6 may receive information corresponding to the occurrence of a fire from the central monitoring device 1. When receiving the information corresponding to the occurrence of fire, the operations of the intake blower 8 and the exhaust blower 9 may be stopped. In this case, the inflow of outside air into the space to be ventilated can be suppressed.
Next, the control device 6 will be described as an example with reference to fig. 3.
Fig. 3 is a hardware configuration diagram of a control device of a ventilation system according to embodiment 1 of the present invention.
The processing circuit can implement the functions of the control device 6. The processing circuit is provided with at least one processor 22a and at least one memory 22b, for example. The processing circuit is provided with at least one dedicated hardware 23, for example.
In case the processing circuitry is provided with at least one processor 22a and at least one memory 22b, the respective functions of the control device 6 are realized by software, firmware or a combination of software and firmware. At least one of the software and the firmware is described as a program. At least one of software and firmware is stored in the at least one memory 22 b. The at least one processor 22a realizes the respective functions of the control device 6 by reading out and executing programs stored in the at least one memory 22 b. The at least one processor 22a is also referred to as a CPU (Central Processing Unit), a Central Processing Unit, a Processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. Examples of the at least one Memory 22b include nonvolatile or volatile semiconductor memories such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash Memory, an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), a magnetic Disk, a flexible Disk, an optical Disk, a cd (compact Disk), a mini Disk (MiniDisc), and a DVD (Digital Versatile Disk).
In the case where the processing Circuit includes at least one dedicated hardware 23, the processing Circuit is realized by, for example, a single Circuit, a composite Circuit, a programmed processor, a parallel-programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination of these. The respective functions of the control device 6 can be realized by a processing circuit, for example. The respective functions of the control device 6 can be realized by a processing circuit, for example, in a unified manner.
For each function of the control device 6, one part may be implemented by dedicated hardware 23, and the other part may be implemented by software or firmware. For example, the function of switching the operation mode of the ventilation system 3 may be realized by a processing circuit as the dedicated hardware 23, and the function other than the function of switching the operation mode of the ventilation system 3 may be realized by reading out and executing at least one program stored in the memory 22b by the at least one processor 22 a.
In this way, the processing circuit implements the functions of the control device 6 by hardware 23, software, firmware, or a combination of these.
Fig. 4 is a schematic diagram of an air conditioning system to which the ventilation system according to embodiment 2 of the present invention is applied. The same or corresponding portions as those in embodiment 1 are denoted by the same reference numerals. The description of this part is omitted.
In fig. 4, the air conditioner 24 is installed in the space to be ventilated. The air conditioner 24 is provided to be able to adjust the temperature of the ventilation target space.
The remote controller 25 is provided in the ventilation target space. The remote controller 25 is provided so as to be able to output information based on an operation from the outside to the air conditioner 24.
At least one indoor unit 4 is provided in the space to be ventilated. One outdoor unit 5 is installed outside the space to be ventilated. When a plurality of indoor units 4 are present, a heating and cooling cycle is formed between one outdoor unit 5 and each of the plurality of indoor units 4.
The operation mode of the ventilation system 3 is set in synchronization with the operation mode of the air conditioner 24.
When the operation mode of the air conditioner 24 is, for example, the air blowing mode, the operation mode of the ventilation system 3 is also the air blowing mode. When the operation mode of the air conditioner 24 is, for example, the cooling mode, the operation mode of the ventilation system 3 is also the cooling mode. When the operation mode of the air conditioner 24 is, for example, the heating mode, the operation mode of the ventilation system 3 is also the heating mode. When the operation mode of the air conditioner 24 is, for example, the automatic mode, the operation mode of the ventilation system 3 is also the automatic mode.
However, when the operation of the air conditioner 24 is stopped by an operation of the remote controller 25 or the like, the operation mode of the ventilation system 3 is changed to the air blowing mode.
According to embodiment 2 described above, the operation mode of the ventilation system 3 is set in synchronization with the operation mode of the air conditioner 24. At this time, if a condition set in advance as a condition that no person is present in the space to be ventilated is satisfied, the operation of the compressor 15 can be stopped. In this case, it is possible to suppress the compressor 15 from operating even when a person is not present. As a result, the power consumption of the ventilation system 3 can be suppressed. By suppressing the power consumption of the ventilation system 3, the electricity fee can be suppressed.
When the operation of the air conditioner 24 is stopped, the operation mode of the ventilation system 3 is the air blowing mode. Therefore, even when the operation of the air conditioner 24 is stopped, the space to be ventilated can be ventilated.
In embodiment 1 or embodiment 2, the output of the compressor 15 may be suppressed when a condition set in advance is satisfied as a condition that no person is present in the space to be ventilated. In this case, when the power consumption of the ventilation system 3 is suppressed to some extent, the space to be ventilated can be kept in a comfortable state to some extent.
In embodiment 1 or embodiment 2, the operation of the ventilation system 3 may be stopped when a predetermined number of years has elapsed since the start of the operation of the ventilation system 3.
