The rotating speed of pump 41 can also be adjusted according to the quantity in the fresh-keeping space for having controlled atmosphere demand in the process of running.
An instantiation is introduced below：There are three fresh-keeping spaces to have controlled atmosphere demand, the rotating speed of aspiration pump is A,
After actual oxygen concentration in two fresh-keeping spaces reaches its preset concentration threshold value, two fresh-keeping spaces and aspiration pump 41 it
Between pipeline close, there is controlled atmosphere demand in the fresh-keeping space of only one of which, and now the adjustment of rotational speed of aspiration pump is B, in last guarantor
Actual oxygen concentration in fresh space reached after its preset concentration threshold value, and its pipeline between aspiration pump 41 is closed, and is taken out
Air pump 41 is out of service.It should be noted that A is more than B.Actual oxygen concentration in all fresh-keeping spaces for having controlled atmosphere demand
Be equal to or less than respective preset concentration threshold value in the case of, aspiration pump 41 in time it is out of service, aspiration pump 41 can be avoided not
Necessary work, extends the service life of aspiration pump 41, effectively reduces energy consumption.In some other embodiment, refrigerating is set
It is standby to be also provided with timer, collected by judging to connect pipeline, pump drainage oxygen rich gas between fresh-keeping space and aspiration pump 41
Whether the time of the gas in chamber reaches preset time threshold, determines whether the atmosphere in fresh-keeping space reaches storage article
Fresh-keeping demand.
