Ventilation control apparatus

Abstract

A ventilation control apparatus of an indoor ventilation system including an intake device configured to take outside air into an indoor space, the intake device capable of changing an intake amount of the outside air, the ventilation control apparatus includes: a people count detection unit configured to determine the number of people who are present in the indoor space, to be outputted as people count information; and a control unit configured to obtain the people count information and control the intake device so that the more the number of people indicated by the people count information is increased, the greater an amount of the outside air to be taken in becomes.

1 . A ventilation control apparatus of an indoor ventilation system including an intake device configured to take outside air into an indoor space, the intake device capable of changing an intake amount of the outside air, the ventilation control apparatus comprising:
 a people count detection unit configured to determine the number of people who are present in the indoor space, to be outputted as people count information; and   a control unit configured to obtain the people count information and control the intake device so that the more the number of people indicated by the people count information is increased, the greater an amount of the outside air to be taken in becomes.   
     
     
         2 . The ventilation control apparatus according to  claim 1 , wherein
 the indoor space includes a plurality of virtually divided sections, wherein   the people count detection unit is configured to output the people count information in each of the plurality of sections, wherein   the intake device includes a plurality of inlets arranged at different spots in the indoor space, the plurality of inlets each capable of changing an amount of the outside air to be taken into the indoor space, and wherein   the control unit is configured to control the intake device so that the outside air to be taken in through an inlet located farther from a section where a determination is made that a person is present is greater in amount than the outside air to be taken in through an inlet located closer to the section where a determination is made that a person is present.   
     
     
         3 . The ventilation control apparatus according to  claim 2 , wherein
 the control unit is configured to control the intake device so that the outside air is taken in only through an inlet located farthest from the section where a determination is made that a person is present.   
     
     
         4 . The ventilation control apparatus according to claim wherein
 the indoor ventilation system includes an exhaust device including a plurality of outlets arranged at different spots in the indoor space, the plurality of outlets each capable of changing an amount of air to be exhausted from the indoor space, the exhaust device configured to exhaust the air in the indoor space to the outdoor, and wherein   the control unit is configured to control the exhaust device so that the air to be exhausted through an outlet located farther from the section where a determination is made that a person is present is greater in amount than the air to be exhausted through an outlet closer to the section where a determination is made that a person is present.   
     
     
         5 . The ventilation control apparatus according to  claim 2 , wherein
 the indoor ventilation system includes a plurality of air conditioners provided respectively in the plurality of sections, the plurality of air conditioners configured to set the plurality of sections at desired temperatures, respectively.   
     
     
         6 . The ventilation control apparatus according to  claim 1 , wherein
 the indoor ventilation system is provided in the indoor space and includes an air conditioner configured to set the indoor space at a desired temperature, and wherein   the control unit is configured to take into the indoor space an amount of the outside air greater than an amount thereof corresponding to the number of people indicated by the people count information, if such a switching instruction is outputted that instructs the air conditioner performing a heating operation to be switched to a cooling operation or if such a switching instruction is outputted that instructs the air conditioner performing a cooling operation to be switched to a heating operation.
