The utility model with two parallel channelling water heat exchangers arranged side by side of heat-transfer surface replace original two groups parallel side by side and be positioned at four channelling water heat exchangers of the relative both sides of centrifugal blower, provide cost savings, reduced floor space.Couple together by the inlet tube and outlet tube of electric T-shaped valve the channelling water heat exchanger, can guarantee that channelling water heat exchanger leaving air temp is stabilized in setting value, make the compression-type refrigeration load maintain certain limit, can not cause leaving air temp excessive or too small because of water yield variation from central air-conditioning.With the medium forced heat-exchanging that air-cooled heat exchanger replaces double pipe heat exchanger that compressor is come out, good refrigeration effect, be not subjected to the water yield and the Temperature Influence of central air conditioner system cold water, simple in structure, cost is low.
Description of drawings:
Fig. 1 is a structure chart of the present utility model.
The specific embodiment:
The air-cooled Duel cold sources airplane ground energy-conserving and environment-protective air-conditioning of the utility model unit is water-cooled first air treatment system of heat transferring medium and is that the compression-type refrigeration of heat transferring medium is that second air treatment system is formed with the cold-producing medium by the cold water that provides with central air-conditioning.First air treatment system is injected from marquis's machine building central air-conditioning cold water through water pump 7 by channelling water heat exchanger 6, carry out heat exchange with air from Hou Jilou or shelter bridge passage, cooled air is at the evaporimeter in second air treatment system under the effect of centrifugal blower 5, be cooled once more, after outlet housing 2 and air supplying hose 1 be admitted in the aircraft cabin that is parked in the airport.The water that channelling water heat exchanger 6 is discharged drains into marquis's machine building central air-conditioning water retention system through water pump 7.Become steam after cold-producing medium in the evaporimeter 4 and the air heat exchange, sucked back compression discharge by compressor 14 and enter cooling in the air-cooled heat exchanger 9, aerofoil fan 10 is to air-cooled heat exchanger 9 forced heat-exchangings, reaches the effect of cooling refrigeration agent.
Channelling water heat exchanger 6 is in parallel two, lays respectively at the air inlet of centrifugal blower 5 rear sides, becomes in-line to arrange with the evaporimeter of centrifugal blower air outlet.
Between outlet housing 2 and the evaporimeter 4 electric heater 3 is arranged, after channelling water heat exchanger 6 heats outside air, again through electric heater heating (whether decision opens as required), after fan housing 2 and air supplying hose 1 provide hot-air for aircraft.
Below the ambient temperature value of setting, the first air treatment system work; The ambient temperature value of setting and more than, first and second air treatment system is worked simultaneously.
Evaporimeter one end is connected with compressor 14 by filter 19, and the other end is connected with compressor 14 through expansion valve 20, magnetic valve 17, ball valve 16, device for drying and filtering 15, reservoir 13, air-cooled heat exchanger 9, shock-absorbing pipe 11.The effect of aerofoil fan 10 is to 9 coolings of air-cooled heat exchanger, makes the refrigerant vapour of HTHP become the refrigerant liquid of low-temp low-pressure.
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 6 surfaces, dehumidifying earlier under the effect of centrifugal blower 5, air after the cooling is again through steam compression type evaporimeter 4 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 6 from terminal central air-conditioning cold water by water pump 7, carry out with outside air that leaving water temperature raises after the heat exchange, extract out by water pump 7 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 6, and this moment, vapor compression type refrigerating system did not participate in the air cooling.The effect of electric T-shaped valve 8 is to guarantee that channelling water heat exchanger 6 leaving air temps are stabilized in setting value, and the compression-type refrigeration load is maintained within a certain range, and can not cause the leaving air temp fluctuation excessive or too small because of the variation of the water yield.
The low-temperature low-pressure refrigerant steam that comes out from evaporimeter passes through suction line, the filter 19 of flowing through, shock-absorbing pipe 11 is inhaled into compressor 14, be compressed into high temperature and high pressure gas by compressor again, high-temperature high-pressure refrigerant enters air-cooled heat exchanger 9 by discharge duct, the refrigerant vapour of HTHP is forced to carry out heat exchange with outside air under the effect of aerofoil fan 10, refrigerant vapour is cooled into liquid, through liquid line, reservoir 13, device for drying and filtering 15, ball valve 16, magnetic valve 17 arrives expansion valve 20 places, liquid refrigerant is become the gas-liquid mixture of low-temp low-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 filter 19 of flowing through once more.Enter next circulation once more, go round and begin again like this airborne transfer of heat to the cold water of central air-conditioning, to realize providing dehumidifying, fresh cold air to aircraft.
