FIELD: process engineering.SUBSTANCE: this invention relates to air cleaner and to forecasting of skip time for this gadget. Air cleaner comprises filtering part to remove toxic gas at air passage. Besides, it allows forecasting of skip time. Note here that air cleaner comprises extra arithmetical processing unit. Said unit allows loading of data on toxic gas concentration in air on filtering part side upstream of airflow, air flow rate through filtering part, air temperature and relative humidity on filtering part side upstream of airflow. Note here that skip time forecast formula wherein toxic gas concentration, flow rate, temperature and relative humidity are used as variables, is programmed in arithmetic processing unit. Said forecasting formula is used to forecast skip time on the basis of said data.EFFECT: skip time forecast even at variation of toxic gas concentration, air flow rate, temperature and relative humidity.57 cl, 13 dwg |
