<p>PURPOSE:To enable room interior carbon dioxide to be reasonably and economically reduced, and environment to be kept comfortable by providing an open air intake stream course and a bypass stream course, with discharge rate controlling means according to the output of a carbon dioxide sensor. CONSTITUTION:On an open air intake stream course 2, the inflow course 13 and outflow course 15 of a thermal sway adsorber(TSA) 6 are provided with control valves 8, 9 consisting of motor valves or motor dampers as discharge rate controlling means, and a bypass stream course 7 is provided with a similar control valve 10. Then, the inlet section of the open air intake stream course 2 is provided with a carbon dioxide sensor 11. Air in the room interior 1 of an exhaust passage 4 is discharged into open air, but most of it enters a feedback stream course 5 and is put together with the open air of the open air intake stream course 2 and is fed into the room interior 1. Besides, the open air taken in the open air intake stream course 2 is divided into the air passing the TSA 6 and the air passing no TSA 6 with the by pass stream course 7. So far as the distribution is concerned, as the carbon dioxide density of the open air gets higher with the output of the carbon dioxide sensor 11, the air quantity is passed more through the TSA 6. This adjustment is executed by adjusting the opening of the control valves 10 and/or 8 based on the output of the sensor 11.</p> |
