Fig. 1 is air treatment system figure of the present invention.
Fig. 2 is a underpass system schematic of the present invention.
Fig. 3 is the bounce device structure chart.
The specific embodiment:
The present invention is made up of two parts: 1. Duel cold sources airplane ground energy-conserving and environment-protective air-conditioning unit (ADM); 2. underpass system (GSS).
1. Duel cold sources airplane ground energy-conserving and environment-protective air-conditioning system (ADW) is to utilize departure hall central air-conditioning cold water (the certain density ethylene glycol-aqueous solution or the NaCl-aqueous solution) to regulate air themperature by channelling water heat exchanger and evaporimeter, for aircraft provides aircondition comfortable, fresh air.
This unit is by cold water is provided with central air-conditioning is the multi-level water cooling formula air treatment system of heat transferring medium and be that the steam compression type air treatment system of heat transferring medium is formed with the cold-producing medium.Two systems comprise as lower member:
The 1-air supplying hose; The 2-outlet housing; The 3-heater; 4,5-steam compression type evaporimeter; The 6-centrifugal blower; 7-channelling water heat exchanger; The 8-water pump; The 9-magnetic valve; The 10-double pipe heat exchanger; 11,18-shock-absorbing pipe; 12-high and low pressure force controller; The 13-reservoir; The 14-compressor; The 15-device for drying and filtering; The 16-ball valve; The 17-magnetic valve; The 19-liquid-sighting glass; The 20-filter; The 21-expansion valve
Operation principle: when environment temperature is higher than more than 30 ℃, outside air is the cooling for the first time of process channelling water heat exchanger 7 surfaces, dehumidifying earlier under the effect of centrifugal blower 6, air after the cooling is again through steam compression type evaporimeter 4,5 cooling for the second time, further the cooling air reaches the requirement of wind pushing temperature at last.Be pressed into channelling water heat exchanger 7 from terminal central air-conditioning cold water by water pump 8, carry out with outside air that leaving water temperature raises after the heat exchange, enter double pipe heat exchanger 10 and carry out heat exchange with the high-temperature high-pressure refrigerant steam, water temperature further raises, and is extracted out by water pump at last to drain in the terminal central air-conditioning return water system.When ambient temperature was lower than 30 ℃, outside air only needed to carry out the requirement that heat exchange just can reach the unit blasting air temperature with channelling water heat exchanger 7, and this moment, vapor compression type refrigerating system did not participate in the air cooling.
The low-temperature low-pressure refrigerant steam that comes out from evaporimeter passes through suction line, the filter 20 of flowing through, wall shake pipe 18 is inhaled into compressor 14, be compressed into high temperature and high pressure gas by compressor again, high-temperature high-pressure refrigerant enters double pipe heat exchanger 10 by discharge duct, the cold water that liberated heat is flowed through is wherein taken away, cold-producing medium is cooled into liquid, through liquid line, reservoir 13, device for drying and filtering 15, ball valve 16, magnetic valve 17 arrives expansion valve 21 places, liquid refrigerant is become the gas-liquid mixture of low temperature and pressure by the throttling step-down, enter evaporimeter 4 and carry out heat exchange with the surperficial air of flowing through, air is cooled and reaches wind pushing temperature, cold-producing medium is heated gasification, enters compressor by the suction line too small multiplexer 20 of flowing through once more.Enter next circulation once more, go round and begin again like this in the water of airborne transfer of heat central air-conditioning, to realize providing dehumidifying, fresh cold air to aircraft.
The two refrigeration source airplane ground energy-conserving and environment-protective air-conditioning units (ADW) of 1-; 28-drip pipe road; 22-band heat-insulation layer air feed steel pipe; The 23-wired hose of blowing; The 24-bounce device; The 27-magnetic valve.
Principle: when aircraft has been stopped, the wired hose 23 of will blowing is pulled out and is connected to the aircraft air inlet, press bounce device 24 " startup " button, the air-conditioning system that is placed in marquis's machine building starts motion, unit is sent through cooling, except that warm cold air enters aircraft cabin inside by the air feed steel pipe 22 of band heat-insulation layer and the wired hose 23 of blowing, and air conditioning is carried out in the cabin handled.Air supply duct outer surface condensate water flows in the water leg, and when water level reach a certain height, magnetic valve 27 was opened, and condensed water is drawn in the central air-conditioning water retention system by discharge tube 28 in the water leg.
After the engine room inside air themperature reaches requirement, press and " stop " button on the bounce device 24, the motion of air-conditioning system unit, air-supply finishes.Treat in the air supplying hose after the air release wired hose to be folded in the underground piping, the aircraft joint is fixed on the bounce device, depresses bounce device at last, guarantees that bounce device 24 flushes with ground and solid and reliable by specific retaining mechanism.
