Embodiment 1
Fresh air pipeline, exhaust duct and return air duct are set up into valve respectively, fresh air and exhaust duct valve, regulation is closed
Return air duct valve increases return air amount, it is ensured that total air output is constant, the temporary enclosed formula system that inside air is circulated in forming chamber
System.In the case where the outdoor airs such as haze, sandstorm are severe, the utility model is by setting the control pair of electrically operated valve linkage
Air-conditioning system carries out local flow improvement, and hybrid air-conditioning system is converted into temporary enclosed formula system, realizes indoor dirty with outdoor
Air is temporarily isolating.Linked when outdoor pollution index is reduced, then by new air-valve, exhaust valve, air returning valve and air-conditioning draught fan
Control is converted to hybrid air-conditioning system.
The utility model is related to two kinds of situations：Controlled by air-conditioning draught fan linkage control device, when outdoor air runs into mist
During the bad weathers such as haze, sandstorm, new air-valve is closed with exhaust valve, and this allows for the outdoor gas with a large amount of pollutants will not
Flow into indoor, it is ensured that the cleanliness factor of room air and the comfort level of personnel, while also reducing the damage to air-conditioner tail end equipment
Bad, air returning valve opens big increasing return air amount, it is ensured that indoor total air output is constant；When outdoor air pollution index is reduced, fresh air
Valve is opened with exhaust valve, and air returning valve turns down reduction indoor return air amount, increases resh air requirement, so as to ensure indoor total air output not
Become.
Embodiment 2
Air-conditioning draught fan linkage prepared by the utility model, its operation conditions is as follows：When outdoor PM2.5 concentration sensing
When device detects outdoor PM2.5 concentration more than 0.075mg/m3, i.e., when Outdoor Air Quality is not up to standard, close new air-valve, air draft
Valve, opens big air returning valve, the operation of system temporary enclosed formula.Run after a period of time, when indoor gas concentration lwevel sensor is examined
When measuring indoor carbon dioxide concentration more than 0.1%, positive opening new air-valve, exhaust valve turns down air returning valve, in primary retirn air system
The aperture of new air-valve is calculated by minimum fresh air ratio under operational mode of uniting, and the aperture of exhaust valve reaches 5-10Pa by room air pressure
Calculate, then open blower fan and surface cooler water valve 18, water wheels clarifier and electrostatic filter are and then opened, so as to ensure fresh air
Quality.System operation for a period of time after, when indoor carbon dioxide concentration drops to below 0.1%, close water wheels clarifier and
Electrostatic filter, is then shut off new air-valve and exhaust valve, and air returning valve is reached into maximum, and system is converted to temporary enclosed system again,
So circulate to ensure indoor air quality and personnel's comfort level.
