Ventilation information display apparatus

Abstract

A ventilation information display apparatus includes functions of a ventilation information acquisition unit and a display unit. The ventilation information acquisition unit acquires required ventilation information indicating a required amount of ventilation, which is an amount of ventilation required in a target space and actual ventilation information indicating an actual amount of ventilation, which is an amount of ventilation of a ventilator installed in the target space. The display unit displays the required amount of ventilation indicated in the required ventilation information and the actual amount of ventilation indicated in the actual ventilation information that are acquired by the ventilation information acquisition unit.

1 . A ventilation information display apparatus comprising:
 processing circuitry to:   acquire required ventilation information indicating a required amount of ventilation, which is a target value of an amount of ventilation in a target space, actual ventilation information indicating an actual amount of ventilation, which is an amount of ventilation of a ventilator installed in the target space, and estimated ventilation information indicating an estimated amount of ventilation, which is an amount of ventilation of the ventilator to be estimated in a case where the ventilator is maintained; and   display the required amount of ventilation indicated in the required ventilation information and the actual amount of ventilation indicated in the actual ventilation information that are acquired, and also display in a case where the required amount of ventilation is greater than the actual amount of ventilation, a message by switching between a message recommending maintenance and a message recommending replacement, depending on whether or not the estimated amount of ventilation is greater than or equal to the required amount of ventilation.   
     
     
         2 . The ventilation information display apparatus according to  claim 1 , wherein
 when the required amount of ventilation is greater than the actual amount of ventilation, the processing circuitry displays insufficiency information indicating insufficiency in an amount of ventilation.   
     
     
         3 . The ventilation information display apparatus according to  claim 1 , wherein
 the required ventilation information indicates the required amount of ventilation for a past reference period,   the actual ventilation information indicates the actual amount of ventilation for the past reference period, and   the processing circuitry displays the required amount of ventilation and the actual amount of ventilation for the past reference period.   
     
     
         4 . The ventilation information display apparatus according to  claim 1 , wherein
 the processing circuitry displays the estimated amount of ventilation indicated in the estimated ventilation information.   
     
     
         5 . The ventilation information display apparatus according to  claim 2 , wherein
 in at least one of cases where the number of occupants in the target space has decreased after the insufficiency information has been displayed and where a fitting that separates the target space has been opened after the insufficiency information has been displayed, the processing circuitry records in past record information, that a ventilation measure has been executed and   the processing circuitry outputs the recorded past record information.   
     
     
         6 . The ventilation information display apparatus according to  claim 5 , wherein
 the required ventilation information indicates the required amount of ventilation for a past reference period,   the actual ventilation information indicates the actual amount of ventilation for the past reference period, and   the processing circuitry outputs the required ventilation information, the actual ventilation information, and the past record information.   
     
     
         7 . The ventilation information display apparatus according to  claim 5 , wherein
 the processing circuitry outputs timing information indicating a recommendation timing for maintenance or replacement for the ventilator, specified from a temporal change in the required amount of ventilation and a temporal change in the actual amount of ventilation.   
     
     
         8 . The ventilation information display apparatus according to  claim 1 , wherein
 the processing circuitry displays the number of people available to enter the target space, specified from a required amount of ventilation per person and the actual amount of ventilation.
