Detailed description of the invention
A kind of air conditioner for electric motor coach adopting Electronic Valve, it comprises two cover evaporator assemblys, a set of condenser assembly, two cover fully-closed vortex compressors, pipeline assembly and controller composition, it also comprises the electric expansion valve being arranged on compressor outlet, the front and back of electric expansion valve all arrange device for drying and filtering, described electric expansion valve comprises valve body 9, as shown in Figure 3, valve body 9 lower end arranges needle-valve 8, what be connected with needle-valve 8 has a levelling pipe and a VERTICAL TUBE, valve body 9 upper end arranges magneto-electric machine 10, magneto-electric machine 10 surrounding arranges at least 4 coils 11, during refrigerating operaton, refrigerant enters from levelling pipe, VERTICAL TUBE flows out, enter from VERTICAL TUBE during heating operation, levelling pipe flows out.
Described evaporator assembly and condenser assembly are installed on Che great Ding, and unit freezes and heats shared a set of pipeline system.Adopt two air return structure, shorten entire length, reduce unit weight.This interior environment system normally can work in the voltage range of the main car power supply DC300V-700V of access, meets the demand of vehicle cooling in summer, winter heating, for passenger provides comfortable environment by bus.
As shown in Figure 1, 2, the utility model air-conditioning assembly comprises the parts such as evaporative condenser assembly, compressor, four-way cock, electric expansion valve, pipeline, and these parts are positioned at enclosure interior.Rear streamlined reefer housing 1, condensation fan 2, blower fan cover plate 3, air intake grid 4, right cap 5, former dome 6 and left cap 7 form the external structure of air-conditioner set, adopting blower fan cover plate 3 and condensation fan 2 directly to leak outside form to reduce air-conditioning total weight, saving condenser caps.
The import and export of compressor are connected with evaporator, condenser respectively, carry out reducing pressure by regulating flow by electric expansion valve, in system operation, control electric expansion valve by compressor exhaust temperature, make it automatically regulate the cold medium flux participating in systemic circulation.In refrigerating/heating operational process, share a set of pipeline system.Wherein, in systemic circulation process, filling coolant quantity is generally as the criterion with during refrigerating operaton, when a/c system operation of heat pump, the circulating refrigerant amount of demand can reduce, now can in gas-liquid separator storage compartment refrigerant, and gas-liquid separator also can prevent compressor liquid hammer, ensure the reliability of compressor, device for drying and filtering is bidirectional flow, saves installing space, reduces Maintenance and Repair, structure is compacter.
As shown in Figure 2, during refrigerating operaton, as shown in " ▼ " in figure, the high-temperature high-pressure refrigerant gas of discharging from compressor enters condenser core through four-way cock, the refrigerant gas of warm high pressure in becoming with external environment heat exchange under the effect of condensation fan, because the spool of electric expansion valve is less, electric expansion valve is easily caused to block if there is foreign matter to enter, therefore at refrigerant gas after moisture impurity etc. removed by device for drying and filtering, enter the battery tube of electric expansion valve again, by flowing out from VERTICAL TUBE after electric expansion valve throttling cooling, then evaporation core body is entered, the gas of low-temp low-pressure is flashed in evaporation core body, thus reduce the temperature of surrounding air environment, air channel into the car under the effect of evaporation fan, reach the effect reducing vehicle interior temperature, thus meet the refrigerant impression by bus of passenger.Get back to four-way cock from evaporator low temperature low pressure gas out, enter compressor through gas-liquid separator and again circulate.During heating operation, as shown in " ▽ " in figure, the high-temperature high-pressure refrigerant gas got rid of from compressor enters evaporator core through four-way cock, the refrigerant gas of warm high pressure in becoming with external environment heat exchange under the effect of evaporation fan, air after temperature raises by evaporation fan sends into air channel, improve the ambient temperature in car, thus reach the object of winter heating.Then air removes through device for drying and filtering the VERTICAL TUBE entering electric expansion valve after moisture impurity etc., flow out from levelling pipe after electric expansion valve throttling cooling, enter condensation core body, the gas of low-temp low-pressure is flashed under condensation fan effect, get back to four-way cock from condenser low temperature low pressure gas out, enter compressor through gas-liquid separator and again circulate.
