Breeze fan in the utility model adopts the VFC mode, but the rotating speed of step-less adjustment blower motor reaches the purpose of regulating the unit blasting air amount, thereby according to different aircraft types, can select suitable air output by demand, energy-conservation more comfortable and hommization.If breeze fan is not taked VFC, then may air output to occur excessive for the aircraft of ting model, in the air-supply power that increases the breeze fan motor, excessive wind speed blows into the air conditioner ventilation pipeline of aircraft, also may damage the air conditioner ventilation pipeline of expensive airframe; On the contrary, the aircraft of big model then deficiency in draught may occur, is difficult to the fresh air and the cooling purpose that provide enough.
The utility model adopts the design of brand-new wind or part return air, both can be lifted on below the air bridge of civil airport, also can be installed on below the air bridge seat, blow to aircraft cabin or driving cabin by air supplying hose, for the aircraft that rests in air bridge provides treated fresh air with certain cleanliness factor and preference temperature, cooling demand with precision equipment in the physiology that satisfies passenger in the aircraft cabin and crew and comfortableness and the cabin, the consumption of Aviation Fuel in the time of can reducing aircraft and wait to fly on ground, prolonged the service life of the expensive air-conditioning system of aircraft autogamy, reduce the airport air ambient and pollute, have higher economic and social benefit.
When aircraft door is not closed, guaranteeing that aircraft cabin has enough new wind to be used to satisfy under the situation of passenger and crew's psychological need, aircraft air condition can suck back the return air of part aircraft cabin by air bridge, reaches purpose of energy saving with the cooling load that reduces refrigeration system.Resh air requirement and return air amount ratio can be regulated continuously, can regulate resh air requirement and return air amount ratio separately in actual demand, thereby guarantee at any time, and aircraft cabin all has enough new wind to be used to satisfy passenger and crew's psychological need.
New return air amount ratio can be regulated according to return air temperature, and control can be taked time formula, return air temperature formula, CO
2The concentration formula.Time formula control is in the guest boards process, and guest's number is from 0～100%, continues about 30 minutes, and resh air requirement then increases according to passage of time continuously by 10～100%.The control of return air temperature formula is the increase according to the aircraft cabin return air temperature, illustrates that at this moment passengers quantity increases resh air requirement gradually increasing in the cabin, reaches till 100% up to resh air requirement.CO
2The control of concentration formula is to adopt CO
2The concentration detector, the CO of hunter cabin return air
2Concentration, thus understand passengers quantity in the cabin, and determine the ratio of new wind, this control mode intelligence, comfortable, hommization, can guarantee at any time under the situation in energy savings as far as possible that aircraft cabin has all enough newly that wind is used to satisfy passenger and crew's psychological need.
After aircraft cabin is closed, then adopt brand-new wind air-supply scheme, by the air supplying hose air-supply, for the aircraft that rests in air bridge provides treated fresh air with certain cleanliness factor preference temperature.
The utility model more can meet country and make great efforts to advocate in Eleventh-Five Year Plan, the requirement of energy conservation type, friendly environment society, meet the actual demand that the Civil Aviation Airport of new period high speed development is built, it has simple and reasonable, flexible operation, can replenish new wind, comfortable energy-conservation, Energy Efficiency Ratio is high and characteristics applied widely.
