Abstract

A control device includes an acquisition unit and a control unit. The acquisition unit acquires first information indicating information on an operating time of a first device and an environmental condition that influences a life of a first instrument provided for the first device, and information on an operating time of a second device and an environmental condition that influences a life of a second instrument provided for the second device. The control unit operates the first device and the second device in conjunction with each other based on the first information acquired by the acquisition unit.

First claim

The invention claimed is:

1 . A control device configured to control a first ventilation device and a second ventilation device that ventilate a same indoor space, the control device comprising:
a controller including a processor, the controller being configured to acquire first information indicating
information on a first operating time of the first ventilation device and an environmental condition that influences a life of a first instrument provided for the first ventilation device, the first operating time being a duration over which the first ventilation device has been operated, and
information on a second operating time of the second ventilation device and an environmental condition that influences a life of a second instrument provided for the second device, the second operating time being a duration over which the second ventilation device has been operated,
the controller being further configured to operate the first ventilation device and the second ventilation device in conjunction with each other based on the first information acquired, wherein each of the first ventilation device and the second ventilation device includes
a suction port through which a fluid is sucked,
a discharge port through which the fluid is discharged, and
a fluid passage connecting the suction port and the discharge port to each other,
the first instrument and the second instrument are filters arranged in the fluid passage, and the information on the environmental condition is information indicating a degree of contamination of the fluid in the fluid passage.

2 . A control device configured to control a first ventilation device and a second ventilation device that ventilate a same indoor space, the control device comprising:
a controller including a processor, the controller being configured to acquire first information on a life of a first instrument provided for the first ventilation device and a life of a second instrument provided for the second ventilation device, the controller being further configured to
set operating states of the first ventilation device and the second ventilation device by allocating a volume of air for each of the first ventilation device and the second ventilation device so as to satisfy a volume of air required for the indoor space, the operating states being set based on the first information acquired, and
operate the first ventilation device and the second ventilation device in conjunction with each other based on the operating states, wherein
each of the first ventilation device and the second ventilation device includes
a suction port through which a fluid is sucked,
a discharge port through which the fluid is discharged,
a fluid passage connecting the suction port and the discharge port to each other, and
a conveyor that is driven by a motor and configured to convey the fluid in the fluid passage,
the first instrument and the second instrument are filters arranged in the fluid passage, the first information is a static pressure of the fluid obtained based on a power consumption of each conveyor and a number of rotations of the motor.

3 . A control device configured to control a first ventilation device and a second ventilation device that ventilate a same indoor space, the control device comprising:
a controller including a processor, the controller being configured to
detect current operating states of first ventilation device and a second ventilation device,
estimate, from the operating states,
a remaining life of a first instrument provided for the first ventilation device and
a remaining life of a second instrument provided for the second ventilation device,

acquire first information indicating the remaining lives of the first instrument and the second instrument that were estimated; and
operate the first device and the second device in conjunction with each other based on the first information acquired, wherein
each of the first ventilation device and the second ventilation device includes
a suction port through which a fluid is sucked,
a discharge port through which the fluid is discharged,
a fluid passage connecting the suction port and the discharge port to each other, and
a conveyor that is driven by a motor and configured to convey the fluid in the fluid passage,
the first instrument and the second instrument are filters arranged in the fluid passage, the controller is further configured to a detect power consumption of each the conveyors and a number of rotations of each of the motors, and to obtain a static pressure of the fluid conveyed by each of the conveyors based on the power consumption of each the conveyors and the number of rotations of each of the motors, the first information is the static pressure of the fluid conveyed by each of the conveyors.

4 . The control device of claim 1 , wherein
the controller is configured to operate the first ventilation device and the second ventilation device in conjunction with each other such that the lives of the filter of the first ventilation device and the filter of the second ventilation device end at a same timing.

5 . The control device of claim 1 , wherein
the controller is configured to operate the first ventilation device and the second ventilation device in conjunction with each other such that the lives of the filter of the first ventilation device and the filter of the second ventilation device end sequentially.

6 . The control device of claim 1 , wherein
the controller is configured to receive information on a predetermined operation of the filter of the first ventilation device and the filter of the second ventilation device based on a user's operation, and the controller is configured to operate the first ventilation device and the second ventilation device in conjunction with each other based on the first information acquired and the information on the predetermined operation that was received.

7 . The control device of claim 6 , wherein
the information on the predetermined operation is a maintenance schedule for performing maintenance for the filter of the first ventilation device and the filter of the second ventilation device, and the controller is configured to operate the first ventilation device and the second ventilation device in conjunction with each other such that the lives of the filter of the first ventilation device and the filter of the second ventilation device end in accordance with the maintenance schedule.

8 . The control device of claim 7 , wherein
the maintenance schedule includes a timing of replacement of the filter of the first ventilation device and the filter of the second ventilation device.

9 . The control device of claim 6 , wherein
the information on the predetermined operation is a power consumption of the first ventilation device and the second ventilation device and a first cost required for maintenance for the filter of the first ventilation device and the filter of the second ventilation device, and the controller is configured to operate the first ventilation device and the second ventilation device in conjunction with each other such that a total cost including the first cost and a second cost is a target value or less, the second cost being a cost that is required until a maintenance timing for the filter of the first ventilation device and the filter of the second ventilation device.

10 . The control device of claim 9 , wherein
the first cost includes a required cost for installation, replacement, inspection, or repair of the filter of the first ventilation device and the filter of the second ventilation device, the required cost including a component cost required for maintenance or a labo
