Operation principle and process:
The present invention is used when outdoor temperature is lower than room temperature.
Application method one: negative pressure air flowing cooling device nearby window, door are closed, the air-inlet window for needing convection current is only retained
Family or door open power supply using remote controler, close direction inductor, start fan blade, make indoor negative pressure air flowing cooling dress
Gas near setting is discharged to outdoor, and negative pressure air, which flows cooling device air pressure nearby, to be reduced, and wind goes out from window, the door of convection current by room
Interior is flowed into outside, to accelerate indoor and outdoor air convection current, quickly interior is made to be reduced to outdoor temperature.
Application method two: in opening chamber convection current in need window, door, use remote controler open power supply, open wind direction
Inductor sets secondary wind direction induction delay time, starts fan blade.When direction inductor senses that outdoor wind direction and negative pressure are empty
When flow of air cooling device wind direction is consistent, negative pressure air flows cooling device and operates normally, and accelerates indoor and outdoor air convection current, thus
Accelerate indoor and outdoor temperature exchange；When direction inductor senses outdoor wind in secondary wind direction induction delay time lag twice in succession
To inversely when negative pressure air flows cooling device wind direction, fan blade stops, and blinds is kept it turning on, make indoor and outdoor air naturally right
Stream；When direction inductor incudes outdoor wind direction forward in negative pressure air stream in secondary wind direction induction delay time lag twice in succession
When dynamic cooling device wind direction, blinds is again turned on, and accelerates indoor and outdoor air exchange.
Secondary wind direction is set and incudes delay time lag, is that wind direction quickly changes fan blade is caused to start pass repeatedly in order to prevent
It closes, the time is specifically arranged according to practical service environment, by user's self-setting in secondary wind direction induction delay time lag.
Compared with the prior art, the invention has the beneficial effects that:
The present invention generates negative pressure using space to accelerate indoor and outdoor air convection current, so that indoor and outdoor temperature be accelerated to exchange, makes
With at low cost, effect is good, different regions can make room temperature reduce 2-8 degree；It can be reached by controlling air convection channel door and window
Unrestricted choice one or more room temperature；When direction inductor can prevent outdoor temperature " contrary wind ", hinder air naturally right
Stream；When the design of secondary wind direction inductor delay can prevent outdoor wind direction from quickly changing repeatedly, fan blade starts closing repeatedly.
