PURPOSE:To obtain a comfortable indoor environment by generating the voltage having the 1/f fluctuation with use of a random number train and securing the correlation of time changes among the illumination, the temperature, the air blast flow, and the dark noises in a room. CONSTITUTION:The random numbers are set 101 and at the same time the linear conversion coefficients aj (a1 - an) are set 102. Based on these set random numbers and coefficients, a q-series is produced as a numerical train having the fluctuation of about 1/f shown by an equation (n = 1, 2...). Then this obtained 1/f numerical train undergoes the D/A conversion 104. A 1/f fluctuating voltage generating circuit 105 produces the voltage having the fluctuation of about 1/f based on the analog value of the converted 1/f numerical train. The correlation is secured by the voltage of the circuit 105 among the illuminance 2a, the temperature 3a, the air blast flow 4a, and the dark noise 5a of a light source device 2, a temperature controller 3, a ventilator 4, and a dark noise generator 5 respectively. As a result, the residents can enjoy the comfortable feeling similar to a phenomenon of the natural world. |
