Raw air mass flow makes it easy to concentration increase；If solution concentration is higher than q2, reduce regeneration air flow, to avoid excessive concentration；
If solution concentration is higher than q3, closes regeneration air and supply blower, the no longer moisture in removal solution.Under humidification state, if solution
Concentration is lower than q1, reduces for flux of moisture, too low to avoid solution concentration；If solution concentration is higher than q2, and is in humidification state,
Increase for flux of moisture；If solution concentration is higher than q3, shut down.Above-mentioned q1, q2 and q3 are the pre-set concentration value of system.
In normal operation, pressure is stablized, and solution concentration is stablized.If flow is less than lowest stream magnitude, it may occur however that blocking,
Shutdown inspection filter；If flow is greater than maximum flow value, reduce output power.
