Definitions

  • the present invention relates to a ventilation device.
  • Patent Literature 1 there has conventionally been an air conditioner that controls a compressor in an outdoor device by correcting the rotational speed of the compressor according to the difference between the detected indoor humidity and the indoor temperature during a dehumidifying operation in the air conditioner, that also controls an outdoor fan by correcting the rotational speed of the outdoor fan based on the difference between the detected room temperature and the set indoor temperature, and that performs a dehumidifying operation by alternately performing the operation of the compressor and the operation of the outdoor fan under the corrective control described above.
  • Patent Literature 2 there has been a ventilation air conditioning device including a temperature sensor that measures the outdoor-air temperature, a humidity sensor that measures the outdoor-air humidity, an air conditioning coil that heats the air to be supplied, and a control unit that controls the air conditioning coil based on the measurement results of the temperature sensor and the humidity sensor, in such a manner that the absolute humidity of the air to be supplied reaches a predetermined value.
  • Patent Literature 1 does not take the outdoor temperature and humidity information, or an air conditioning load due to ventilation into account. Therefore, the overall air conditioning operation efficiency is not sufficiently considered. This technique in Patent Literature 1 is not sufficiently adequate for the total control in the air conditioner.
  • parameters for controlling the air conditioning coil are limited to the outside-air temperature and humidity. There is a case where at the start of operation, the humidity in the room is low, and it is therefore necessary to increase the amount of humidification. In that case, when limitations are imposed on the capacity of the air conditioning coil based on the outside-air temperature and humidity conditions, a considerable amount of time is required to bring the interior of the room into a comfortable humidity state. This impairs the comfort.
  • the present invention has been achieved to solve the above problems, and an object of the present invention is to provide a ventilation device that performs an air supply with an optimal amount of dehumidification at the time of introducing the outside air by ventilation, and that is capable of performing an operation that is less likely to cause a change in the indoor humidity.
  • a ventilation device including: a casing that includes an air-supply passage and an exhaust passage; an air-supply blower that is provided in the air-supply passage, and that blows outdoor air into the air-supply passage to form a supplied-air flow in a room; an exhaust blower that is provided in the exhaust passage, and that blows indoor air into the exhaust passage to form an exhaust-air flow to be discharged outside a room; a total heat exchanger that is located between the air-supply passage and the exhaust passage, and accommodated in the casing, and that performs total heat exchange between the supplied-air flow and the exhaust-air flow; an outside-air temperature sensor that measures a temperature of the outdoor air; an outside-air humidity sensor that measures a humidity of the outdoor air; an indoor humidity sensor that measures a humidity of the indoor air; a temperature regulating coil that is capable of changing a cooling capacity at multiple stages, and that dehumidifies
  • the ventilation device of the present invention an effect is obtained where it is possible to perform an air supply with an optimal amount of dehumidification at the time of introducing the outside air by ventilation, and that is capable of performing an operation that is less likely to cause a change in the indoor humidity.
  • FIG. 1 is a top perspective view illustrating a configuration of a ventilation device according to a first embodiment of the present invention.
  • a ventilation device 23 includes a body casing 1, an exhaust blower 2, an air-supply blower 3, a total heat exchanger 4, a temperature regulating coil 5, a humidifying element 6, an exhaust outlet 7, an air-supply outlet 8, an air-supply inlet 9, an exhaust inlet 10, an outside-air temperature sensor 11, an outside-air humidity sensor 12, a target indoor-humidity storage unit 13, a control unit 14, a remote controller 15, an air-passage switching damper 16, an indoor temperature sensor 17, and an indoor humidity sensor 18.
  • the air-supply outlet 8 and the exhaust inlet 10 are provided on the indoor side.
  • the exhaust outlet 7 and the air-supply inlet 9 are provided.
  • the ventilation device 23 has a box structure, and is covered with the body casing 1.

  • the air-supply blower 3 is incorporated in the air-supply passage to form a supplied-air flow.
  • the exhaust blower 2 is incorporated in the exhaust passage to form an exhaust-air flow.
  • the total heat exchanger 4 is located between the air-supply passage and the exhaust passage. The total heat exchanger 4 continuously performs total heat exchange between a supplied-air flow and an exhaust-air flow to convert the outdoor air to the air to be supplied, and convert the indoor air to the air to be exhausted.
  • the humidifying element 6 is provided on the windward side of the air-supply outlet 8 within the air-supply passage.
  • the humidifying element 6 is provided on the windward side of the air-supply outlet 8 within the air-supply passage.
  • the temperature regulating coil 5 that dehumidifies the air to be supplied, and adjusts the amount of humidification.
  • a water supply pipe 19 is connected to the humidifying element 6. During the humidifying operation, a water supply valve 20 is opened to supply water for humidification through the water supply pipe 19 to the humid
  • the air-passage switching damper 16 switches between an air passage 26 through which the air to be exhausted is delivered to the total heat exchanger 4, and a bypass air passage 27 through which the air to be exhausted is delivered directly to the exhaust blower 2 not through the total heat exchanger 4.
  • the air-passage switching damper 16 is closed, the exhaust air passes through the total heat exchanger 4, and total heat exchange between the exhaust air and the supplied air is continuously performed.
  • the air-passage switching damper 16 is opened, the exhaust air passes through the bypass air passage 27 provided beside the total heat exchanger 4, and is then converted to the air to be exhausted, and discharged outdoors by the exhaust blower 2.
  • the ventilation device 23 When an outside-air temperature Toa is lower than the indoor temperature in the transitional season, the ventilation device 23 operates in such a manner as to open the air-passage switching damper 16 to deliver the indoor air to the bypass air passage 27 in order to perform cooling with the outside air by bypass ventilation. In the summer and winter season such as when an air conditioning load is generated, the ventilation device 23 operates in such a manner as to close the air-passage switching damper 16 to deliver the indoor air to the total heat exchanger 4 in order to perform total heat-exchange ventilation intended for the indoor-air heat recovery.
  • the control unit 14 controls the ventilation operation.
  • the remote controller 15 receives a switching operation of operating modes and the like.
  • the target indoor-humidity storage unit 13 has a target value of the indoor humidity stored therein.

  • the indoor humidity sensor 18 measures an actual indoor humidity RHra, that is, the humidity in the room.
  • the indoor temperature sensor 17 and the indoor humidity sensor 18 are provided between the exhaust inlet 10 and the total heat exchanger 4.
  • the control unit 14 determines the heating capacity of the temperature regulating coil 5 based on the temperature information that is a measurement result of the outside-air temperature Toa measured by the outside-air temperature sensor 11, and based on the humidity information that is a measurement result of the outside-air humidity RHoa measured by the outside-air humidity sensor 12.
  • the air having passed through the total heat exchanger 4 is heated by the temperature regulating coil 5.
  • the air, having been heated by the temperature regulating coil 5, passes through the humidifying element 6, and is humidified, and then supplied from the air-supply outlet 8 to the interior of the room. At this time, the amount of humidification and the discharge-air temperature are adjusted by the dehumidification amount in the temperature regulating coil 5.
  • FIG. 2 is a flowchart illustrating an operation flow of the ventilation device.
  • the control unit 14 executes initial determination control for determining the initial operation state (Step S1). Thereafter, the control unit 14 shifts to steady operation control (Step S2). When there is no operation to finish the device operation (NO at Step S3), the control unit 14 continues the steady operation control. When there is an operation to finish the device operation (YES at Step S3), the control unit 14 finishes the operation of the ventilation device 23.
  • FIG. 3 is a flowchart illustrating a flow of initial determination control.
  • the control unit 14 reads an actual measured indoor relative humidity RHra, and a target indoor relative humidity RHm (Step S11).
  • the control unit 14 compares the actual measured indoor relative humidity RHra with the target indoor relative humidity RHm (Step S12).
  • the control unit 14 operates the ventilation device 23 in a dehumidifying mode A (Step S13).
  • the control unit 14 controls the temperature regulating coil 5 such that the dehumidification capacity becomes 100%.
  • the control unit 14 determines the humidity state in the room (Step S14). The determination of the humidity state is performed based on whether the actual measured indoor relative humidity RHra is equal to or higher than a thermo-off humidity RHoff. When the actual measured indoor relative humidity RHra is equal to or higher than the thermo-off humidity RHoff, the control unit 14 determines that it is necessary to continue the dehumidifying operation. In order to prevent chattering, it is appropriate to set the thermo-off humidity RHoff to a value that is approximately 5% lower than the target indoor relative humidity RHm.
  • the control unit 14 When the air in the room is in a state where it needs to be dehumidified (YES at Step S14), the control unit 14 operates the ventilation device 23 in a dehumidifying mode B (Step S15).
  • the control unit 14 In the dehumidifying mode B, in order to maintain a constant indoor humidity, the control unit 14 automatically determines the capacity of the temperature regulating coil 5, at which the humidity of the air supplied from the ventilation device 23 becomes the target indoor relative humidity RHm, based on the outside-air temperature Toa and the outside-air humidity RHoa.
  • Reference data in which a combination of the outside-air temperature Toa and the outside-air humidity RHoa is brought into correspondence with the capacity value of the temperature regulating coil 5, that is a so-called map, is held in the control unit 14. Based on the map, the control unit 14 decides the capacity value of the temperature regulating coil 5.
  • the control unit 14 When the air in the room is not in a state where it needs to be dehumidified, that is, when the actual measured indoor relative humidity RHra is lower than the thermo-off humidity RHoff (NO at Step S14), the control unit 14 operates the ventilation device 23 in a dehumidifying mode C (Step S16). In the dehumidifying mode C, it is not necessary to promote dehumidification by using the temperature regulating coil 5. In order to suppress the decrease in discharge-air temperature, and condensation on the discharge grille, which are caused by overcooling and dehumidification, the control unit 14 sets the operation capacity of the temperature regulating coil 5 to 0%, that is, the ventilation device 23 continues the dehumidifying operation in a thermo-off state.
  • the control unit 14 permits only a heat-exchange ventilation operation, and prohibits a bypass ventilation operation in which heat exchange is not performed. Therefore, the ventilation device 23 can suppress an abrupt decrease in humidity due to ventilation during the steady operation, maintain a high-humidity state at a constant value for a long time, and ensure the comfort.
  • FIG. 4 is a flowchart illustrating the operation flow in steady operation control.
  • the control unit 14 confirms which dehumidifying mode the ventilation device 23 is currently in (Step S21).
  • the control unit 14 determines whether the actual measured indoor relative humidity RHra remains higher than the target indoor relative humidity RHm (Step S22).
  • the control unit 14 causes the ventilation device 23 to continue the operation in the dehumidifying mode A in order to continue to increase the indoor humidity (Step S23).
  • the control unit 14 causes the ventilation device 23 to shift to the dehumidifying mode B (Step S24). Due to this control, while monitoring the outside-air temperature Toa and the outside-air humidity RHoa, the control unit 14 operates the temperature regulating coil 5 at an optimal coil-capacity value, and causes the ventilation device 23 to continue the dehumidifying operation.
  • the control unit 14 determines whether the actual measured indoor relative humidity RHra remains lower than the thermo-off humidity RHoff (Step S25). When the actual measured indoor relative humidity RHra remains lower than the thermo-off humidity RHoff (NO at Step S25), the control unit 14 causes the ventilation device 23 to continue the operation in the dehumidifying mode C (Step S26). When the actual measured indoor relative humidity RHra is increased by ventilation, and then becomes equal to or higher than the thermo-off humidity RHoff (YES at Step S25), the control unit 14 causes the ventilation device 23 to shift to the dehumidifying mode B (Step S24).
  • the control unit 14 determines whether the actual measured indoor relative humidity RHra is equal to or higher than an unlimited-capacity return humidity RHon (Step S27). When the actual measured indoor relative humidity RHra is equal to or higher than the unlimited-capacity return humidity RHon (YES at Step S27), the control unit 14 causes the ventilation device 23 to shift to the dehumidifying mode A (Step S23). In order to prevent chattering, it is appropriate to set the unlimited-capacity return humidity RHon to a value that is approximately 5% higher than the target indoor relative humidity RHm.
  • the control unit 14 determines whether the actual measured indoor relative humidity RHra is equal to or higher than the thermo-off humidity RHoff (Step S28). When the actual measured indoor relative humidity RHra is equal to or higher than the thermo-off humidity RHoff (YES at Step S28), the control unit 14 maintains the operation of the ventilation device 23 in the dehumidifying mode B (Step S24). When the actual measured indoor relative humidity RHra is not equal to or higher than the thermo-off humidity RHoff (NO at Step S28), the control unit 14 causes the ventilation device 23 to shift to the dehumidifying mode C (Step S26).
  • FIG. 5 is a time chart illustrating an example of the operation of the ventilation device according to the first embodiment.
  • the control unit 14 executes initial determination control. Because the actual measured indoor relative humidity RHra is higher than the target indoor relative humidity RHm, the control unit 14 causes the ventilation device 23 to start the dehumidifying operation in the humidifying mode A.
  • the control unit 14 causes the ventilation device 23 to shift from the dehumidifying mode A to the dehumidifying mode B.
  • the control unit 14 causes the ventilation device 23 to shift from the dehumidifying mode B to the dehumidifying mode C.

  • the control unit 14 switches the dehumidifying mode of the ventilation device 23 from the dehumidifying mode B to the dehumidifying mode C.
  • the control unit 14 switches the dehumidifying mode of the ventilation device 23 from the dehumidifying mode B to the dehumidifying mode A. Due to this control, the ventilation device 23 performs an operation with the maximized amount of dehumidification in order to decrease the indoor humidity as quickly as possible.
  • the control unit 14 determines that the indoor humidity falls within the target range, and causes the ventilation device 23 to continue the energy-efficient humidifying operation in the dehumidifying mode B.

Due to this operation, while maintaining a constant humidity in the room, the control unit 14 switches over the dehumidifying mode when the actual measured indoor relative humidity RHra deviates from the target indoor relative humidity RHm, and can make the actual measured indoor relative humidity RHra closer to the target indoor relative humidity RHm as quickly as possible. This can improve the comfort in a shorter time.
