Abstract
PURPOSE:To prevent the decrease of the room cooling and room heating effects and also prevent the waste of energy by feeding back the degree of pollution of the air in a room after ventilation to the value of pollution for starting ventilation which starts the operation of a ventilation fan. CONSTITUTION:A storage device 5 stores the minimum degree of pollution so far. And, an arithmetic device 6 can increase or decrease automatically a value of pollution 14 which starts ventilation in proportion to a standard signal 12 and also artificially can increase and decrease it by a sensitivity regulating device 9. In the comparison by a comparison device 7, if the degree of pollution in a room which is indicated by a pollution signal 11 goes beyond the value of pollution 14, the CPU outputs ON signal 15 which operates a ventilation fan 2 to a switching device 8 through the output port of a memory device ID. With this arrangement the ventilation fan 2 operates and ventilation starts. As the ventilation proceeds, the degree of pollution of the air in the room falls, and when the degree of pollution indicated by the pollution signal 11 is below the pollution value 14 which starts ventilation, an OFF signal 16 to stop the ventilation fan 2 and renewal signal 13 are outputted. The renewal signal 13 renews the standard signal stored in the storage device 5.
