の大きな原因になるという問題がある。However, the above-mentioned conventional measurement / analysis system of a multi-chamber diffusion system has some problems. For example, since the gas concentrations in multiple rooms are measured using a single gas concentration analyzer, a gas concentration analyzer must be installed in a measurement hut, and long tubes must be laid from there to each room in the target building. I have to. Therefore, not only is it troublesome to lay the tube,
It is necessary to secure a space for the measurement hut and the tube, which impairs simplicity and practicality. Moreover, since it takes about 1 minute per chamber to measure the gas concentration, if one gas concentration analyzer attempts to obtain simultaneous and continuous changes in gas concentration in each chamber, It is necessary to repeat the measurement for each room and approximately obtain the simultaneous gas concentration of all the rooms by the interpolation calculation before and after the time. Therefore, as the number of rooms handled increases, not only does it take time to measure one cycle, but this approximation error also becomes large, which is a major cause of error when estimating ventilation air volume based on changes in gas concentration. There is a problem.

It is an object of the present invention to provide a measurement / analysis system for a multi-room diffusion system that can be used.

よい。The present invention is not limited to the above embodiment, but various modifications can be made. For example, in the above-described embodiment, the analyzer 7 and the gas injection / measurement unit 6 in each chamber are connected by a communication line for synchronization, and the gas released over time is recorded in the recording device via the communication line. Although it was configured to collect and analyze the measured values of the amount and gas concentration, the recording device of the gas injection / measurement unit eliminates the cable connection with the analysis device, for example, floppy disk, compact disk or other recording medium. The measured values of the amount of released gas and the gas concentration are recorded separately and independently over time, and the recording medium is taken out and analyzed by the analyzer 7.
It may be configured so that the read batch analysis processing is appropriately performed. That is, the system may be configured online via the communication line, or may be configured offline via the recording medium. Further, although the gas discharge schedule is set in the gas injection / concentration measurement control device 4 in each room from the analysis device 7, the gas discharge schedule may be set in each gas injection / concentration measurement control device 4. In short, it is only necessary that the measured values of the amount of released gas and the gas concentration recorded over time be synchronized in time between the chambers.Therefore, each gas injection / measurement unit is equipped with a clock, and each gas is completely independent. Even if the release of the gas and the measurement of the gas concentration are performed, the measured values of the gas release amount and the gas concentration may be obtained at each time.
