Detailed description of the invention
As it is shown in figure 1, a kind of energy-conservation comfortable car air-conditioner, it includes the air-conditioner housing 13 being positioned at roof, arranges condenser assembly and evaporator assembly in air-conditioner housing 13.Condenser assembly mainly includes condenser cover 2, condenser core 1 and condensation fan 3；Evaporator assembly mainly includes evaporator core 6, evaporation fan 11 and vaporizer lid 12；Wherein, condenser cover 2 and vaporizer lid 12 dock with air-conditioner housing 13 respectively, and so design can make construction weight lighter, reaches light-weight design requirement.
The present invention solves the relation of condenser intake and windage, along car direction of advance, condenser assembly is front, and evaporator assembly is rear；And arc-shaped pod apertures 14 is set in the front portion of condenser cover 2, strip air-inlet grille 15 is set in the both sides of condenser cover 2, strip air-inlet grille 15 has water conservancy diversion flange, so design reduce air intake windage, beneficially wind field uniform.Communicate between the strip air-inlet grille 15 of condenser caps both sides and condenser inner shell, thus solve two problems: one, when the low traveling of vehicle speed, air intake surface can be expanded, improve condensation effect, thus improve Energy Efficiency Ratio；Two when vehicle high-speed advances, and so can reduce car resistance as earial drainage face, thus improve car load efficiency.
Condenser core 1 in condenser assembly is arranged on the front portion of air-conditioner housing 13, and condenser uses the arrangement of big parallel-flow heat exchanger.The big parallel-flow heat exchanger of monolithic is bigger due to its long and wide distance, arrange bad easily strain cracking, the present invention uses parallel flow condenser core body 1 lateral separation longitudinally adding reinforcing plate at interval of during 300-600mm, condenser core 1 lateral arrangement, surrounding is fixed, and forming the front elevation angle with roof, the elevation angle is 4-8 degree, can think the arbitrary value in 4,5,6,8 degree.The present invention overcomes technical barrier, uses monolithic big parallel flow condenser assembly, it is to avoid multiple core body parallel shunt uneven, connecting line becomes simple, decreases trouble point, the air-conditioning reliability of raising.
It addition, arrange condensation fan 3 between condenser cover 2 and condenser core 1, condensation fan 3 is arranged in fixed plate, is arranged so as to be effectively formed gas-tight silo, improves the air quantity by heat exchanger, thus improves blower fan effective efficiency.And condensation fan 3 in W type or the type of falling W arrange, be arranged so as to arrange more blower fan, thus reduce integral air conditioner weight under limited width, reduce driving oil consumption.
In evaporator assembly, evaporator core copper pipe uses along wind direction staggered arrangement piping mode, and above-mentioned staggered arrangement refers to: with two arranged with a pipe of pipe and adjacent row is arranged for equilateral triangle, and evaporator core copper pipe is that 4-6 arranges.
For improving air-cleaning function, arrange air filtration and purification apparatus at the return air inlet of evaporator assembly, from the external-to-internal of return air inlet, above-mentioned air filtration and purification apparatus includes that granule slightly imitates filter course, polarized fibers filter course, electric purification elementary layer, ultraviolet light wave elementary layer and nano photo-catalytic elementary layer successively.During work, control system sends high level signal to air filtration and purification apparatus, make air filtration and purification apparatus internal polarization fibrous filter layer, EC electric purification elementary layer, ultraviolet light wave elementary layer and nano photo-catalytic elementary layer must be electrically excited each organizational unit to run, the air draught that passes by is carried out purified treatment, effectively filters the dust in air and impurity.In addition, in order to the moment can provide high-quality air, avoid purifier dirty stifled after continue to work, the present invention installs air pressure harvester before and after air filtration and purification apparatus, air pressure harvester is connected with control system, control system, by judging its pressure differential, reminds user's timely cleaning device.
Another aspect of the present invention, it is provided that a kind of humiture combine regulation function, in order to ensure the operation of air conditioner temperature humidity range human comfort.The present invention arranges the outer temperature sensor 8 of car between the return air inlet and evaporator core 6 of evaporator assembly, at Bus inner layout vehicle interior temperature sensor 10 and humidity sensor 7；The outer temperature sensor 8 of car, vehicle interior temperature sensor 10 are all connected with control system with humidity sensor 7.By collection and the calculating of these parameters, final control compressor and the rotating speed of blower fan, thus the temperature and humidity of air is controlled in the range of human comfort.
