Further illustrate the detailed description of the invention of the utility model back-positioned type air conditioner for electric motor coach below in conjunction with accompanying drawing, but it is noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1.A kind of back-positioned type air conditioner for electric motor coach, containing framed structure 01, control and power-supply system part 02, cools wind channel 021, superstructure 03, understructure 04 and bottom construction 05.Described framed structure 01 adopts hardware.Described control and power-supply system part 02, cooling wind channel 021, superstructure 03, understructure 04 and bottom construction 05 are all made integral structure component relative one by one and be arranged in described framed structure 01, again whole air-conditioning is arranged on the rear portion of electrobus, becomes back-positioned type air conditioner for electric motor coach.
See Fig. 1 and 2.The utility model back-positioned type air conditioner for electric motor coach air supply mode is: in the superstructure 03 of described framed structure 01 by upper strata first air outlet 011 and upper strata second air outlet 012(see Fig. 3) upper strata be set evaporate top, 07(upper strata, air port) and rear end, evaporator return air inlet 010(upper strata); Condenser ventilation inlet 06(lower floor both sides are set in the understructure 04 of described framed structure 01), condenser air outlet 08(lower floor rear end) and lower floor evaporate air port 09(lower floor front end).
See Fig. 1 and 4.Described framed structure 01 adopts the metal framework structure of three layers.Described control and power-supply system part 02 are arranged on the top of described framed structure 01.Described control and power-supply system part 02 are arranged on separately the rear portion of top layer directly over framed structure 01 as electric assembly, this status requirement well-ventilated.In described control and be provided with two between power-supply system part 02 and described condenser air outlet 08 and cool that wind channel 021(is continuous sees Fig. 2), condensation fan 041 can be utilized to drive portion of air to flow by described cooling wind channel 021, ensure the heat radiation of control and power-supply system part 02.
Described control and power-supply system part 02 go to control separately the right evaporation fan 3 of the left evaporation fan in upper strata 1 and upper strata, lower floor's evaporation fan 2, condensation fan 041 and motor driven compressor 9 by frequency converter, therefore, described control and power-supply system part 02 are containing two evaporation fan frequency converters, condensation fan frequency converter, three vertical DC frequency-changeable compressor frequency converters and an a set of air-conditioning logic controller and relevant high and low voltage switches, thus the independent startup realized upper strata railway carriage or lower floor's railway carriage air-conditioning or closedown.
Continue and see Fig. 4.On the upper strata of described framed structure 01, superstructure 03 is set.Described superstructure 03 is containing the left evaporation fan in upper strata 1, the right evaporation fan 3 in upper strata, lower floor's evaporation fan 2 and evaporator core 13.Described evaporator core 13 adopts an integral structure component and is arranged at the left evaporation fan in described upper strata 1, the right evaporation fan in upper strata 3 and between lower floor's evaporation fan 2 and described evaporator return air inlet 010.
In the lower floor of described framed structure 01, understructure 04 is set.Described understructure 04 is containing condensation fan 041, condenser core 5 and expansion valve 4, dryer 8, motor driven compressor 9, metal bellow 10, gas-liquid separator 11 and four-way cock 12.Described condensation fan 041 adopts three to exchange condensation fan (AC blower fan of exhausting), is arranged on before condenser core 5 in vertical state :centre arranges a double volute evaporation fan, is blown to automobile lower deck compartment air channel by middle air channel; Both sides respectively arrange a single spiral case and exchange evaporation fan, for blowing to automobile imperial air channel.Described interchange condensation fan has that pressure head is low, the feature of little power consumption, and the life-span is long, noise is low, non-maintaining.
Described motor driven compressor 9 adopts three vertical DC frequency-changeable compressors, is arranged on arranging together with refrigeration piping and other refrigeration parts (comprising described expansion valve 4, dryer 8, metal bellow 10, gas-liquid separator 11 and four-way cock 12) of described framed structure 01 lower end below.Because described vertical DC frequency-changeable compressor is permagnetic synchronous motor, the efficiency of motor driven compressor 9 can be improved.During installation, tackle described motor driven compressor 9 and carry out damping process: use the parts such as metal bellow 10 and Sound-proof material to pass in compartment with the vibration and noise of avoiding described motor driven compressor 9, affect the traveling comfort that electrobus is taken.
Described expansion valve 4 adopts heating power expansion valve or electric expansion valve.Described electric expansion valve controls by pulse motor switch valve core the refrigerant flow entering evaporator fast, can significantly improve the Energy Efficiency Ratio of air-conditioning refrigeration plant.
Continue and see Fig. 1 and 4.In the lower floor of described framed structure 01, bottom construction 05 is set.Described bottom construction 05 is containing insulating mat 6, cushion blocking 7.
In enforcement, venetian blinds can be set at described upper strata first air outlet 011 and air outlet 012 place, upper strata second (see Fig. 3).When the right evaporation fan 3 of the left evaporation fan in upper strata 1 and upper strata is opened, under the effect of blast, described louver is opened, and realizes upper strata and ventilates.When needing the air-conditioning stopping imperial, the right evaporation fan 3 of the left evaporation fan in upper strata 1 and upper strata stops, and corresponding compressor 9 is also shut down; At this moment, described louver is closed under the effect of himself gravity, can not form the situation of wind-fall stream.Closed condition is in because upper strata evaporates air port 07, air pressure in the railway carriage of upper strata can be lower than the air pressure in lower floor railway carriage, and in lower deck compartment, have return air to enter evaporator return air inlet 010(see Fig. 2), therefore, the wind in imperial can not be back in lower floor's railway carriage.
When the utility model back-positioned type air conditioner for electric motor coach is installed, one section of vibration being flexible coupling to reduce air-conditioning should be arranged to transfer on vehicle body in the junction in air-conditioning and vehicle body air channel and the wind noise eliminated and cause because a part of air-flow flows fast can be played, the traveling comfort that raising electrobus is ridden.
The utility model back-positioned type air conditioner for electric motor coach, to the air-conditioning of electrobus, is especially significant to double-layer electric coach air conditioner and topological design thereof, and its Social benefit and economic benefit is very significant.
