Description
Technical field
The utility model belongs to motor train compartment equipment, specifically compartment air supply air-conditioner equipment and electric power system operation scheme technical field.
Background technology
Motor train unit air-conditioning unit is to regulate air themperature, humidity, air-flow velocity, the isoparametric visual plant of cleanliness in the motor train unit car, is the important composition that directly affects motor train unit vehicle indoor comfort.
Existing CRH2 EMUs 1 joint two ends at the bottom of car, compartment are symmetrically installed with two small-sized, lightweight interior environment systems.The air outlet of interior environment system is communicated with the air delivery duct that is arranged on bottom, floor, guest room, and is communicated with the air outlet of top board position; Return air inlet is connected with the air return duct of air in the inhalation vehicle.During summer condition, air mixes in blending bin with the fresh outer gas of sending into by the air delivery duct from fresh wind port in the guest room that air return duct sucks, by being arranged on the compartment filter of interior environment system return air inlet, carry out interchange of heat at indoor heat converter, be cooled to cold air, send into the guest room from car body both sides duct outlet, provide cold wind to the passenger.During winter condition, during from the air return duct air amount, mix with fresh outer gas equally, by being arranged on the filter of interior environment system return air inlet, by the electric heater heating, the path by identical with cold air provides warm braw to the passenger.
The deficiency that existing motor train unit air-conditioning unit exists is mainly reflected in: (1) is present, and the motor train unit electric apparatus mounted on vehicle is powered fully from supply network, all come from the conventional energy resources generating, and high speed train all adopts the totally enclosed compartment.Yet, because the problem of the aspects such as contact system space structure size, electrical connection, insulation causes the supply network system failure to take place frequently; Simultaneously, because the pantograph structure has dynamo-electric unification, outdoor layout, dynamic duty, does not have the characteristics such as for subsequent use, in case so railway power supply net et out of order will directly affect the normal operation of train traction electric power system, and then affect the normal operation of other electrical equipments of train.In addition, conditioning unit self also is prone to fault.Since China's high ferro is started, in operation, occur tens of times because the supply network fault causes the motor train unit outage, vehicle load equipment quits work.Especially when breaking down summer, vehicle interior temperature sharply raises, and passenger's traveling comfort reduces greatly, even the symptoms such as uncomfortable in chest, heatstroke appear in the part passenger.(2) horsepower input is 20KW during CRH2 motor train unit air conditioner refrigerating, horsepower input is 22KW when heating, be train maximum load equipment of power consumption except traction, accounted for 70% of vehicular electrical equipment total energy consumption, train energy-saving also becomes the important directions of technological improvement.
The utility model content
Above deficiency in view of prior art, the purpose of this utility model provides one and is embedded with the generating of motor train unit roof photovoltaic array as working power, the work of assist train a/c system is kept the airiness in the train passenger compartment and is regulated to ensure the conditioning unit of motor train unit vehicle indoor comfort to reach energy-conserving action when power supply trouble or breakdown of equipment under normal operation.
The purpose of this utility model is to realize by following means.
Motor train unit solar power auxiliary air conditioner, reach main fresh wind port 2, H Exch 5 and air outlet 7 by successively series connection setting by compression refrigeration equipment 4 and consist of compartment air-conditioning branch road, arrange one by the auxiliary air conditioner supply air system of assisting fresh wind port 8, assisting new wind air delivery duct 9 and air conditioner unit 3 and return air blending bin 6 to consist of; Be provided with pneumatic and heat exchange equipment in the described air conditioner unit 3; The electrical source of power of described auxiliary air conditioner supply air system adopts and is arranged on motor train unit carriage roof photovoltaic array.
The principle of work of motor train unit solar airconditioning is: the photovoltaic array 1 of roof obtains driving the power supply of solar air-conditioner system work by opto-electronic conversion, new wind is inhaled into from auxiliary fresh wind port 8, and by assisting new wind air-supply passage 9 to send into air conditioner unit 3, in air conditioner unit 3, carry out interchange of heat (refrigeration or heating), send into again new wind and return air blending bin 6, with suck from return air inlet 7 and mix by the return air that return air channel is sent into, then enter H Exch 5 and carry out interchange of heat, the air after obtaining processing is sent in the guest room again.
Compare with prime mover group air-conditioning unit, the advantage of the utility model motor train unit solar airconditioning has:
The newly-increased two groups of air conditioner units 3 in one joint compartment, without any change, the utility model changes little to body construction to the original a/c system structure of motor train unit, and technological requirement is low, reduces improvement cost.
The new wind that newly-increased air conditioner unit 3 just sucks fresh wind port is sent into first the air element processing by air supplying hose and is sent into blending bin again, actual is the state that has changed new wind, on the original a/c system mode of operation of motor train unit and not impact of control, principle is simple, is easy to realize.
Newly-increased air conditioner unit 3 can freeze and heats new wind, can satisfy summer and winter two kinds of operating modes, and practicality is stronger.
The a/c system that increases as its working power, has reduced motor train unit electrical equipment load with the generating of roof photovoltaic array, has greatly played energy-conservation effect, and research is learnt and can be made motor train unit Energy Intensity Reduction about 20%.
The photovoltaic array generating is as newly-increased a/c system working power, even power supply trouble or breakdown of equipment occur, also can ensure the normal operation of solar air-conditioner system, blower fan 12 in the air conditioner unit also can start, guarantee the airiness in the guest room, guaranteed to a certain extent the traveling comfort in the guest room.
