Electrofilter 9 is exactly a two-stage filter, then the air to processing through indoor apparatus of air conditioner carries out secondary filter, more preferably
The purpose for reaching purification outdoor air, then the air after filtration is sent into into interior through air supply duct 7.
Above-mentioned fresh air cooperate with return air air-supply anti-haze air-conditioning system method of work, close fresh air pipeline 3 on fresh air
Exhaust valve 2 on valve 4 and exhaust duct 1, adjusts the air returning valve 6 on return air duct 5 to increase return air amount, it is ensured that total air output is not
Become, form the temporary enclosed formula system of indoor inside air circulation.So arrange mainly by new air-valve 4, exhaust valve 2 and return
The coordinated operation of air-valve 6 is sufficient to ensure air output, and creates temporary enclosed system, can make the dirt of air-conditioning system and outdoor
Air exclusion, the purpose of air-supply is reached by the circulation of room air, it is ensured that the cleanliness factor of wind pushing air.
Operation principle of the present invention is as follows：
Fresh air pipeline, exhaust duct and return air duct are set up into respectively valve, fresh air and exhaust duct valve is closed, return air is adjusted
Pipeline valve is increasing return air amount, it is ensured that total air output is constant, forms the temporary enclosed formula system of indoor inside air circulation.Together
When, can louvre blade wheel or electrostatic filter etc. be installed additional according to customer demand to improve IAQ.
Embodiment 1
Fresh air pipeline, exhaust duct and return air duct are set up into respectively valve, fresh air and exhaust duct valve is closed, return air is adjusted
Pipeline valve is increasing return air amount, it is ensured that total air output is constant, forms the temporary enclosed formula system of indoor inside air circulation.
In the case that the outdoor airs such as haze, sandstorm are severe, the present invention is controlled to air-conditioning system by arranging electrically operated valve linkage
Local flow improvement is carried out, hybrid air-conditioning system is converted to into temporary enclosed formula system, realized indoor temporary with outdoor foul atmosphere
When isolate.When outdoor pollution index is reduced, then changed by new air-valve, exhaust valve, air returning valve and air-conditioning draught fan coordinated signals
For hybrid air-conditioning system.
The present invention relates to two kinds of situations：Controlled by air-conditioning draught fan linkage control device, when outdoor air runs into haze, sand
During the bad weathers such as dust storm, new air-valve is closed with exhaust valve, and this allows for the outdoor gas with a large amount of pollutants and may not flow into
It is 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, return
Air-valve opens big increasing return air amount, it is ensured that indoor total air output is constant；When outdoor air pollution index is reduced, new air-valve with row
Air-valve is opened, and air returning valve turns down reduction indoor return air amount, increases resh air requirement, constant so as to ensure indoor total air output.
Embodiment 2
Air-conditioning draught fan linkage prepared by the present invention, its operation conditions is as follows：When outdoor PM2.5 concentration sensors are detected
When outdoor PM2.5 concentration is more than 0.075mg/m, i.e., when Outdoor Air Quality is not up to standard, new air-valve, exhaust valve are closed, open big returning
Air-valve, the operation of system temporary enclosed formula.After operation a period of time, when indoor gas concentration lwevel sensor detects indoor two
When oxidation concentration of carbon is more than 0.1%, positive opening new air-valve, exhaust valve turns down air returning valve, in primary-air recirculating system operational mode
The aperture of lower new air-valve is calculated by minimum fresh air ratio, and the aperture of exhaust valve reaches 5-10Pa and calculates by room air pressure, then
Blower fan and surface cooler water valve 18 are opened, water wheels clarifier and electrostatic filter is and then opened, so as to ensure the quality of fresh air.System
After system operation a period of time, when indoor carbon dioxide concentration drops to below 0.1%, water wheels clarifier and electro static filtering are closed
Device, 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 circulation
To ensure indoor air quality and personnel's comfort level.
