Principle of the present invention:
The course of work of a kind of frostless condensation heat regenerative solution dehumidification aircraft earth surface air-conditioning case of the present invention is divided into air-supply process and regenerative process.
Air-supply process: after new wind first filters formation pure air by air cleaner 21, enter air channel 22, pass through heating, heating is adopted to carry out temperature adjustment during heating condition, enter dehumidifier 61 after temperature adjustment to dehumidify, then enter the first prime evaporimeter 321 to cool, then enter the first rear class evaporimeter 322 to cool further, then enter the second prime evaporimeter 421 to cool, then after the compression of the first high pressure blower 24 and the second high pressure blower 25, increasing temperature and pressure becomes high static air, eventually pass the second rear class evaporimeter 422 and carry out cooling temperature adjustment, air outlet 27 is entered by electric fire-damper, then aircraft cabin is delivered to by special air supplying hose.This process condenser heat adopts traditional air-cooled condenser to discharge, and is respectively the first condenser 33 and the second condenser 43.Dehumidizer solution from dehumidifier top spray, packing layer surface formed uniform liquid film slowly flow down.Dehumidifier 61 adopts cross flow to arrange, air channel arranges that easily, occupation of land space is little, and heat and mass effect is better.Meanwhile, the heat produced in dehumidification process discharges cabinet by the swabbing action of the second axial flow blower 14 and the first axial flow blower 13.
Regenerative process: in the described aircraft air condition unit non-air-supply stage, the regenerative process of dehumidification solution can be carried out.This unit selects built-in evaporating type condensing regenerator 67, is built-in thermal source with the condensation heat of cold-producing medium in the first condenser 33, and dehumidifying weak solution continuously sprays outside evaporative condenser coil pipe 68.In addition, air is from bottom to top blown over outside coil pipe, makes sub-fraction weak solution absorb heat and evaporate.Under evaporation, the heat outside the coil pipe that falls apart, thus the object reaching the built-in refrigerant gas cooling of coil pipe, condensation.Simultaneously also because the heat absorption evaporation of weak solution achieves regeneration of waste liquor.
The invention has the beneficial effects as follows:
The invention solves the problem of the easy frosting of conventional airplane ground air conditioner unit running process; achieve aircraft earth surface air-conditioning to run continually and steadily for a long time; without the need to shutting down defrosting; leaving air temp is not by the impact of frosting; export refrigerating capacity more steady; make interior of aircraft amenity higher, run convenient.Adopt condensation heat regenerative solution dehumidification, both decreased the heat consumption of solution dehumidification system, and prevented again condensation heat to be discharged in environment and cause pollution.
The present invention adopts the design of all-fresh air or part return air, can be installed on below air bridge seat, by air supplying hose air-supply in aircraft cabin or driving cabin, for the aircraft resting in air bridge provides the treated air with certain cleanliness factor and preference temperature.
