Detailed description of the invention
As shown in accompanying drawing 1-2, a kind of pure electric coach air-conditioning being provided with electric expansion valve, comprise air-conditioner housing 1, evaporation fan 2, evaporator core 3 and air-conditioning lid 13, described evaporator core 3 is connected with electric expansion valve 4, electric expansion valve 4 is connected with four-way change-over valve 5, four-way change-over valve 5 also respectively with gas-liquid separator 7, compressor 10 is connected with condenser core 13, the gas vent of gas-liquid separator 7 is also connected with the air entry of compressor 10, the gas outlet of compressor 10 is connected with condenser core 11, outdoor temperature sensor 8 is arranged at condenser air inlet, exhaust gas temperature sensor 9 is arranged on the gas exhaust piping of compressor 10, described electric expansion valve 4, outdoor temperature sensor 8 is all connected with electric-controlled box 6 with exhaust gas temperature sensor 9, other electrical connection is prior art.
Described electric expansion valve 4 is arranged in evaporimeter.
Described electric-controlled box 6 is arranged at evaporimeter return air inlet place.
The course of work of the present utility model is as follows: during refrigerating operaton, the high-temperature high-pressure refrigerant gas of discharging from compressor 10 enters condenser core 11 through four-way change-over valve 5, the refrigerant gas of warm high pressure in becoming with external environment heat exchange under the effect of condensation fan 12, enter electric expansion valve 4 again and flow out by its throttling cooling is rear, then evaporator core 3 is entered, the gas of low-temp low-pressure is flashed in evaporator core 3, thus reduce the temperature of evaporator core 3, under the effect of evaporation fan 2, air in cooled car is sent into air delivery duct in car, to reach the object reducing vehicle interior temperature.Get back to four-way change-over valve 5 from evaporator core 3 low temperature low pressure gas cold-producing medium out, enter compressor 10 through gas-liquid separator 7 and again circulate.During heating operation, the high-temperature high-pressure refrigerant gas got rid of from compressor 10 enters evaporator core 3 through four-way change-over valve 5, the refrigerant gas of warm high pressure in becoming with environment inside car heat exchange under the effect of evaporation fan 2, thus improve the temperature of evaporator core 3, under the effect of evaporation fan 2, air in the car be warmed is sent into air delivery duct in car, to reach the object promoting vehicle interior temperature.The cold-producing medium of gaseous state enters electric expansion valve 4 and flows out by its throttling cooling is rear afterwards, enter condenser core 11, under condensation fan 12 acts on, flash to the gas refrigerant of low-temp low-pressure and get back to four-way change-over valve, then enter compressor 10 through gas-liquid separator 7 and again circulate.
Described electric expansion valve 4 is driven by electric-controlled box 6, its opening value can adjust according to the detected value of the detected value of the outdoor temperature sensor 8 in air-conditioning system and compressor exhaust temperature sensor 9, and then the cold medium flux that can realize in air-conditioning system running in adjustment System pipeline, with the running status making system all be in higher energy efficiency under various operating mode.Thus the power consumption of the seasonal energy efficiency of elevator system, reduction air-conditioning system, increase the course continuation mileage of electric motor coach.Because the Adjustment effect of system cold medium flux could reflected from the outlet air temperature of compressor after certain operation circulation, thus judge whether the adjustment of this electronic valve is suitable for, thus the adjustment of electronic valve is not carried out constantly, but has the timing adjustment in a time interval.
The beneficial effects of the utility model:
(1) in system operation, control electric expansion valve by compressor exhaust temperature, make it automatically regulate the cold medium flux participating in systemic circulation, make system be in optimal operational condition, improve system seasonal energy efficiency ratio (seer).
(2) regulate the aperture of electric expansion valve by timing, can ensure air-conditioning system in the winter time in heating operations condenser core outlet temperature higher than 0 DEG C, reduce system defrost number of times, improve heating capacity, save main car electric energy.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for a person skilled in the art, under the prerequisite not departing from the utility model general idea; can also make some changes and improvements, these also should be considered as protection domain of the present utility model.
