The function of state is placed in cancellation state.
After intelligent fresh air system enters energy-saving and noise-reducing pattern, because the Room is objective or the fresh air of other non-bedroom room areas is sent
Wind and return air have been closed, in order to avoid sky of the air mass sensor 12 in detection parlor or other non-bedroom room areas
During makings amount state change, mistakenly change the air-supply direct current variable frequency motor 10 of fresh air main frame 1, return air direct current variable frequency motor 11 to
More high-speed state（When air quality is poorer, air-supply direct current variable frequency motor 10, return air direct current variable frequency motor 11 rotating speed it is higher,
Blown and return air air quantity with providing bigger fresh air）, air mass sensor 12 is changed into fresh air main frame 1 by information and worked shape
The purpose that the function of state is placed in cancellation state is, it is to avoid mistakenly changes the working condition of fresh air main frame 1, causes energy-saving and noise-reducing
Purpose can not realize.
Due to the Electric air valve I 8 on the control area ajutage 4 of no man's land, control area backwind tube 5, Electric air valve
II 9 are reduced or close, and reduce air output and the consumption of return air amount of no man's land, therefore the fresh air main frame 1 of the slow-speed of revolution is blown
The resh air requirement requirement in bedroom or someone region is met with return air state, because the wind speed of fresh air main frame 1 is reduced, air-supply direct current becomes
Frequency motor 10, the power consumption of return air direct current variable frequency motor 11 are greatly lowered, and noise is also greatly lowered, so as to reach energy-conservation, drop
The purpose made an uproar.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
