Formula roof；Glass curtain wall, building Nan Qiang, adjustable damper and sloped roof form attached sunspace.
The technical solution that the present invention solves the method technical problem is to provide a kind of operation of building energy conservation aeration structure
Method, it is characterised in that this method is specific as follows:
The operation method of spring and summer transition season: every layer of the ground Nan Qiang air-valve and every layer of north wall air-valve, the lingering remnants of past customs are opened
Valve is closed；Adjustable damper is opened, the air channel outlet of attached sunspace is opened；Air in attached sunspace adds through sunlight
Heat, temperature increase, and atmospheric density reduces, and form ascending air, generate draft, due to the temperature on spring and summer transition season building north
The south is more below built lower than interior of building, so that constantly being passed through often by the cold air that every layer of north wall air-valve enters the room
The ground the Nan Qiang air-valve of layer enters attached sunspace, to make indoor air flows, achievees the effect that gravity-flow ventilation, cold air
Introducing can suitably reduce room temperature；
The operation method of summer:
When outdoor temperature is lower than room temperature, glass curtain wall air-valve, every layer of the ground Nan Qiang air-valve and every layer are opened
North wall air-valve, remaining air-valve are closed；Adjustable damper is opened, the air channel outlet of attached sunspace is opened；Outdoor air at this time
Density is greater than room air density, and air-flow is entered the room from glass curtain wall air-valve through every layer of the ground Nan Qiang air-valve, then through every layer
North wall air-valve flow to outdoor, form the gravity-flow ventilation under hot pressing function, play the role of pre-cooling to room air；
In summer day operation of air conditioner, glass curtain wall air-valve is opened, remaining air-valve is closed；Adjustable damper is opened, is opened
The air channel outlet of attached sunspace；Hot pressing principle is flowed using air, enters the air sucked from glass curtain wall air-valve
Into attached sunspace, gas is heated in attached sunspace, forms ascending air, and the air duct through attached sunspace is discharged to room
Outside, so that the temperature of building Nan Qiang be effectively reduced, it is made to generate heat-insulated effect；
The operation method of autumn and winter transition season:
Under normal circumstances, adjustable damper is put down, contacts it with sloped roof, closes the air duct of attached sunspace
Outlet；Every layer of the ground Nan Qiang air-valve and every layer of the roof Nan Qiang air-valve are opened, remaining air-valve is closed；When solar irradiation be mapped to it is attached
