The specific embodiment
As shown in Figure 1, a kind of energy-conservation comfortable car air-conditioner, it comprises the air-conditioner housing 13 that is positioned at roof, and condenser assembly and evaporator assembly are set in air-conditioner housing 13.Condenser assembly mainly comprises condenser cover 2, condenser core 1 and condensation fan 3; Evaporator assembly mainly comprises evaporator core 6, evaporation fan 11 and evaporimeter lid 12; Wherein, condenser cover 2 and evaporimeter lid 12 dock with air-conditioner housing 13 respectively, and design can make construction weight lighter like this, reaches light-weight design requirement.
The present invention is for solving the relation of condenser intake and windage, and along car direction of advance, condenser assembly is front, and evaporator assembly is rear; And circular-arc pod apertures 14 is set in the front portion of condenser cover 2, in the both sides of condenser cover 2, strip air-inlet grille 15 is set, have water conservancy diversion flange on strip air-inlet grille 15, design reduces air intake windage like this, is conducive to wind field even.Between the strip air-inlet grille 15 of condenser lid both sides and condenser inner shell, communicate, thereby solved two problems: one,, when low the advancing of vehicle speed, can expand air intake surface, improve condensation effect, thereby improve Energy Efficiency Ratio; Two when vehicle high-speed advances, and can be used as earial drainage face, can reduce car resistance like this, thereby improves car load efficiency.
Condenser core 1 in condenser assembly is arranged on the front portion of air-conditioner housing 13, and condenser adopts the arrangement of large parallel-flow heat exchanger.The large parallel-flow heat exchanger of monolithic is because its long and wide distance is larger, arrange bad very easily strain cracking, when adopting parallel flow condenser core body 1 lateral separation at interval of 300-600mm, the present invention longitudinally adding stiffener, 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, adopts the large parallel flow condenser assembly of monolithic, and a plurality of core bodys shunting in parallel of avoiding is uneven, and connecting line becomes simply, has reduced trouble point, the air-conditioning reliability of raising.
In addition, between condenser cover 2 and condenser core 1, condensation fan 3 is set, condensation fan 3 is arranged on fixed head, and layout can effectively form gas-tight silo like this, improves by the air quantity of heat exchanger, thereby improves blower fan effective efficiency.And condensation fan 3 is W type or the type of falling W is arranged, layout can be arranged more blower fan under limited width like this, thereby reduce integral air conditioner weight, reduce driving oil consumption.
In evaporator assembly, evaporator core copper pipe adopts along the wind direction mistake pipe mode of arranging, and above-mentioned mistake row refers to: two pipes with pipe and adjacent row with row are that equilateral triangle is arranged, and evaporator core copper pipe is that 4-6 arranges.
For improving air-cleaning function, return air inlet place at evaporator assembly arranges air filtration and purification apparatus, and above-mentioned air filtration and purification apparatus comprises that from the external-to-internal of return air inlet particle is slightly imitated filter course, fibrous filter layer, electric purification elementary layer, ultraviolet light wave elementary layer and nano photo-catalytic elementary layer polarize successively.During work, control system is sent 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 obtain electric each organizational unit operation that excites, the air draught that passes by is carried out to purified treatment, effectively filtered airborne dust and impurity.In addition, in order constantly to provide high-quality air, avoid that purifier is dirty still to work on after stifled, the present invention installs air pressure harvester in the front and back of air filtration and purification apparatus, air pressure harvester is connected with control system, control system is by its pressure differential of judgement, the timely cleaning device of reminding user.
Another aspect of the present invention, provides a kind of humiture associating regulatory function, in order to guarantee that operation of air conditioner is at the comfortable temperature humidity range of human body.The present invention arranges temperature sensor 8 outside car between the return air inlet of evaporator assembly and evaporator core 6, 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, finally control the rotating speed of compressor and blower fan, thereby the temperature and humidity of air is controlled in the scope that human body is comfortable.
